All values shown are for illustration purposes only.

1A and 1B are two perspective views of an exemplary embodiment of the portable lighting device 10 according to the present device, respectively. 1C and 1D are two perspective views of an exemplary embodiment of a portable lighting device 10 according to the device having a mounting bracket 60. 2A to 2D are various views of the exemplary luminaire 10 of FIGS. 1A to 1D showing a swivel luminaire head 40 of the luminaire that has moved to various alternating positions. 3A to 3E are a side view, a top view, a bottom view, a front end view, and a rear end view of one of the exemplary lighting devices 10 of FIGS. 1A to 1D, respectively.

The portable illuminating device 10 includes a illuminating device body portion 20 and has a front end portion 12 and a rear end portion or a tail end portion 14, and is between the front end portion 12 and the tail end portion 14. Is defined as the longitudinal axis 16. The illuminator body 20 includes a housing 30 and a illuminator head 40 swivelably attached to the housing 30 by a hinge or swivel shaft 36 that includes one or more hinge pins or pivot pins 37. The housing 30 preferably has an internal cavity for accommodating a power source, eg, a battery, which battery can be accessed by removing the tail cap 24. The illuminating device body 20 also includes an actuator 22 for selectively controlling the light source of the illuminating device 10 or a plurality of light sources, has a lens 26 facing rearward, and has a rear end portion of the illuminating body 20. It has a removable tail cap 24 that closes 14.

The pressing actuator 22 on the illuminating device body 20 operates an electric switch inside the illuminating device 10, for example, inside the housing 30, so that when the illuminating device head 40 is directed forward. A first light source included in the illuminator head 40 is controlledly energized to generate light in the forward direction substantially parallel to the axis 16 and is behind the rearward facing lens 26. The light sources of 2 are controlledly energized to generate light in the rearward direction substantially parallel to the axis 16.

The illuminator head portion 40 includes a head portion housing 42 including two support arms 44. The two support arms 44 extend rearward from the head housing 42 for connection with a hinge or swivel shaft 36 so that the illuminator head 40 is swingable with respect to the illuminator housing 30. .. The illuminator head 40 rotates up and down, for example, at least about 90 degrees with respect to the illuminator housing 30 and the longitudinal axis 16. Illustrative alternating positions of the illuminator head 40 at about +45 degrees, about +90 degrees, about -45 degrees, and about -90 degrees of turning are shown, but the illuminator head 40 is about turning. It may move to and be placed in any desired alternative position between +90 degrees and about -90 degrees.

The lens 46 is provided at the front end portion 12 of the illuminating device head portion 40 in order to pass the light generated by the internal light source. The lens 46 is held by the lens ring 48 in the head housing 42. The lens ring 48 is threaded so that it can be removed or is permanently attached, for example by press fit, adhesive, ultrasonic welding, or other suitable means. The light emitted by the light source of the illuminator head 40, emitted through the lens 46, is usually an illumination beam, for example a relatively thin or spotted beam that is common in portable illuminators.

The lens 26 is located proximal to the rear end 14 of the illuminator 10 in order to allow the light produced by the light source in the housing 30 to pass generally backwards, eg, substantially parallel to the longitudinal axis 16. It is provided. In some applications, the light emitted rearward from the lens 26 provides a safety beam or beacon. The safety beam or beacon identifies the location of the illuminator 10, and thus the user and / or wearer of the illuminator 10. One common safety luminaire situation usually includes a firefighter with a blue safety beacon. Blue safety beacons are somewhat easier to identify in a fire and smoke environment, where the fire emits significant light at the edges of the red-orange-yellow spectrum. The light emitted through the lens 26 is preferably a relatively wide or radial beam, which allows the light to be visible over a relatively wide range and is optional. May be the desired color or multiple colors.

The clip 50, eg, the elongated clip 50, is provided so that the illuminator 10 can be attached to, for example, a clip on an object such as a pocket, belt, vest, tool carrier, structure, or other object. The clip 50 has an elongated clip arm 52 extending in the longitudinal direction along the outside of the illuminating device body 20, for example, the housing 30, with the clip end 52N closely adjacent to the illuminating body 20. The clip 50 is preferably made of an elastic or spring material, which allows the clip arm 52 to move out of the illuminator body 20 and, when released, with the clip arm 52. Any object between the illuminator body portion 20 tends to be pressed against the illuminator body portion 20, thereby attaching the illuminator 10 relatively firmly to the object.

Preferably, the clip 50 is configured to rotate around the illuminator body 20 and the longitudinal axis 16 over at least a limited rotation range. This limited range of rotation is, for example, a rotation of about 45 degrees or less, preferably from its central position, which is exactly the opposite of the actuator 22 and about 90 degrees from the axis of the hinge or pivot 36. It is about ± 22.5 degrees in either direction. In one exemplary embodiment, the clip 50 is rotatable around the housing 30 by about ± 15 degrees, and the end of the clip 50 is attached to a column at the front end of the housing 30. It is held on the housing by the end cap 34. Thus, when the clip 50 moves (rotates) with respect to the housing 30, the distal end 52N of the clip arm 52 moves along an arcuate path adjacent to the outer surface of the housing 30.

A significant advantage appears to be the result of providing two degrees of freedom for arranging the illuminator head 40 with respect to the housing 30. One degree of freedom is due to the swivelability of the illuminator head 40 with respect to the housing 30, and a second degree of freedom is due to the revolving flexibility of the clip 50 with respect to the housing 30.

For example, if the user clips the luminaire 10 into a pocket or other feature such that the luminaire body 20 is generally vertical in front of the user, the luminaire head 40 directs light forward or forward. -It may swivel up and down in the upward direction, eg, towards the work area, and in addition, the luminaire 10 uses the relative rotatability of the luminaire housing 30 and the clip 50. , May rotate left or right. Furthermore, when a light source that produces light through a rearward-facing lens 26 is energized with the illuminator 10 so clipped to a person, the light emitted through the lens 26 will stand up to the user. It is directed downwards to illuminate the surface of the lens, thereby improving the safety of movement.

The clamp or bracket 60 may be provided for use in the luminaire 10, whereby the luminaire 10 is attached to the edge of a hard object, such as a firefighter's helmet, another helmet, or a hard hat. May be worn or fitted. The mounting bracket 60 is preferably clamped into a clamp member 62 of a certain shape, for example, the edge of the object may be inserted and by tightening, for example, one or more clamp screws 63. Includes a C-shaped clamp member 62 that may have an open side. The clamp member 62 is preferably attached to or connected to the illuminator 10 at its end away from the clamp screw 63.

Thus, the luminaire 10 is supported by the object to which the mounting bracket 60 is attached. In normal use, the luminaire 10 is attached to the lower edge of a helmet or other headgear, usually at a position close to the side of the user's head, whereby the longitudinal axis 16 is generally Nearly horizontal, pointing forward and backward, so that the light emitted through the lens 46 is generally directed forward of the user and the light emitted through the lens 26 is generally directed backward of the user. There is.

A preferred embodiment of the clamp member 62 has a base 64 at its end distal to the clamp screw 63. A pair of bracket arms 66 extend outward from the base 64 to define a space or passage between them. There are grooves 67 on the inwardly facing surface of each bracket arm 66 near the intersection of each bracket arm 66 and the base 64. Both, the two grooves 67 define a space of size and shape that receives the elongated clip arm 52 of the clip 50, whereby the mounting bracket 60 slips onto the clip arm 52 and also the clip arm 52. The mounting bracket 60 and the luminaire 10 may be conveniently mounted and separated from the mounting bracket 60.

In normal use, the mounting bracket 60 is believed to be mounted to be held on a helmet or other headgear, while the luminaire 10 inserts the clip arm 52 of the clip 50 into the groove 67 of the bracket 60. It is attached by this and is removed by removing it from the groove 67. The clip arm 52 passes through a space between a relatively wide portion 52B that can be securely held in the groove 67 of the bracket 60 and the bracket arm 64, thereby allowing the clip 50 to be separated from it. It should be noted that it has a relatively thin end 52N which is designed to.

4A and 4B are exploded views of the exemplary luminaires of FIGS. 1A to 1D, showing various components of the luminaire. 4C to 4F are partially exploded perspective views of parts of the luminaire body portion, showing the attachment of the clip and the rotation of the attachment around the body portion of the illuminator. 5A to 5E are various cross-sectional views of the exemplary illuminators of FIGS. 1A to 1D, taken in different planes, respectively.

The housing 30, which is the main housing for the luminaire 10, is internal for receiving a power source, such as a CR-123 lithium battery, or a lithium ion battery of the type 18650, or a battery such as an AA alkaline battery. It has a cavity. The battery can be attached and detached through the rear end of the internal cavity when the tail cap 24 is removed, for example by turning it open. The seal ring 30S, such as the O-ring, is located in the circumferential groove 30G around the threaded end of the housing 30. The annular contact ring 30R is located behind the threaded end of the housing 30, eg, the housing 30, for electrical contact with the outer ring of the contact spring 24S that is located and held in the inner recess of the tail cap 24. Seated on the edge.

The circular opening in the circular feature 30C on the top of the housing 30 receives the switch plunger 22P covered by an elastic switch boot or cover 22C. The switch boot 22C is held in place by a holding ring 22R which may be fixed by adhesive, ultrasonic welding, or another suitable fixing means. When the switch boot 22C is pressed, the switch boot 22C and the plunger 22P move toward the inside of the housing 30 and press against the electric switch 208 mounted on the electric circuit board 200 in the housing 30. Activate.

An opening at the front end of the housing 30 provides access for insertion and assembly of various components into the housing 30. Among these, there is an electronic circuit board 200 that lies in a plane substantially parallel to the top of the housing 30 so that the switch 208 on the electronic circuit board 200 is activated by the switch plunger. It is arranged under 22P, and the light emitting diodes (LEDs) L1 and L2 are located at a desired position with respect to an optical element, for example, a reflector 26R. The reflector 26R resides behind the lens 26 located in the rear-facing opening of the D-shape on the housing 30. Normally, switches 22 and 208 serve to control all of the on / off and operation mode selections for the luminaire 10.

The connection between the circuit board 200 and the battery in the housing 30 is made via the conductors 202 and 210 attached to the respective contact pads on the circuit board 200, for example soldered or crimped. Will be. The front battery contact 202 has a C-shaped hook 202T at its apex. The C-shaped hook 202T is configured to be mounted near the front edge of the circuit board 200, for example, near the center of the edge, at which point the housing is soldered in place to the contact pad. It has a D-shaped center contact for electrical contact with the front terminals of the 30 batteries, eg, the positive electrode (+) of the battery, usually. The elongated conductor 210 has a C-shaped hook 210T at its front end. The C-shaped hook 210T is configured to be attached at the front edge of the circuit board 200, eg, a contact 202 near the center of the edge, but at an insulated portion, at this position. , Soldered in place. The elongated conductor 210 is slightly offset at its rear end 210R, which fits tightly between the contact ring 30R and the inner wall of the threaded end of the housing 30, and optionally solders. Attached or welded together. Thereby, when the battery is in the housing 30 and the tail cap 24 is fastened onto the housing 30, between the circuit board 200 and the rear terminal of the battery, for example, usually its negative electrode (-) terminal. , Conductor 210, contact ring 30R, and contact spring 24S provide electrical connectivity.

The housing 30 is arranged in a straight line facing each other to receive a fixing means 37, for example, a pivot pin 37, to provide a hinge or a swivel shaft 36 for rotatably supporting the illuminator head 40. It has a hole 36H. The pair of O-rings 36S provide both a seal and a source of friction for holding the illuminator head 40 in a desired pivot position swiveled relative to the housing 30 by the user. Each trim cap 37C snaps in place to cover the exposed end of the Axis pin 37, or is otherwise fixed in place by, for example, adhesive or ultrasonic welding.

Each of the pair of opposing conductors 204 has its own C-shaped hook 204T at its apex. The C-shaped hook 204T is configured to be mounted near the side edges of the circuit board 200, for example, near the front ends of the respective side edges, and at this position, each is, for example, in place. It is soldered. Each conductor 204 has a flat portion having an annular ring or hole inside that extends downward adjacent to the inner surface of the housing 30, where the annular ring or hole is a hole in the housing 30. It is in line with the portion 36H. When the Axis pins 37 are in place, each conductor 204 serves as one end of a slip ring connection with the corresponding annular ring and hole of each conductor 220. The conductor 220 extends rearward along the inner surface of the support arm 44 of the illuminator head housing 42. Each Axis pin 37 provides an electrical connection between the respective annular rings of the conductor 202 and the conductor 220, thereby providing a pair of slip ring electrical connections through the swivel shaft 36. As a result, electric power may be provided to the light source of the illuminator head 40 beyond those swivel axes 36.

The interface ring 39 fits into the opening in the front end of the housing 30 and receives the front end 38. Both the interface ring 39 and the front end 38 are held in the housing 30 by adhesive, ultrasonic welding, or another suitable fixing means, thereby the circuit board 200 and the components 202 of the circuit board 200, Holds 204, 210 in place in the housing 30. The housing end 38 has a pillar 38P located at the center of the annular mounting ring 54 of the clip 50 for receiving light. An O-ring 54S disposed in a groove surrounding the column 38P is supported against the annular mounting ring 54, thereby holding the clip 50 in a desired rotational position where the clip 50 is moved by the user. , It is designed to provide a force to suppress by friction. Grease or other lubricant may be applied to the O-ring 54S to allow it to move more easily while the frictional retention in place is maintained. The end cap 34 is secured to the front end 38 of the housing, for example by adhesive, ultrasonic welding, or another suitable fixing means, whereby the clip 50 is rotatable and rotatable over the housing 30. It is designed to be permanently held on the housing 30. In this way, the clip 50 is movable (rotatable) around the longitudinal axis 16 of the lighting device 10 with the elongated clip arm 52 of the clip 50 adjacent to the outer surface of the housing 30.

In a preferred embodiment, the rotational movement of the clip 50 is restricted by the shoulder 38S of the front housing end 38. The shoulder 38S limits the rotational movement of the short section 55 of the clip 50 that connects the annular mounting ring 54 to the elongated clip arm 52. The limit of rotational movement of the clip 50 can be in the range of more than about 90 degrees, but in normal embodiments, the rotation is about 45 degrees, or about 30 degrees, if desired. May even be limited to. The angle limitation is defined by the angular position of the shoulder 38S, and the permissible rotation angle may be substantially centered at a position rotated about 180 degrees from the top side of the housing 30 and the illuminator 10. Note that it is preferable.

Preferably, optionally, the rotational movement of the clip 50 around the housing 30 is relatively symmetrical in both directions around the center position. This central position is in the exact opposite position of the switch actuator 22 (eg, rotated about 180 degrees from the switch actuator 22), thereby pushing the actuator 22 when the lighting device 10 is attached to a person or object. This may cause the switch actuator 22 to be activated, eg, turned on and off, and placed in any available, programmable operating state. The actuator 22 is preferably a push button actuator that responds to being pushed radially toward the housing 30.

The illuminator head portion 40 includes a head portion housing 42 having a circular opening at its front end. A reflector 42R fits into this circular opening. The reflector 42R has a circular front end to which the lens ring 48 snap fits, but instead, for example, if the lens ring 48 has a male threaded portion on which it is attached by a threaded portion. There is. The annular lens cage and the seal 48R have a circumferential groove on the inner surface thereof. The lens 46 fits in this peripheral groove. For example, the lens 46 and the cage 48R are held inside the lens ring 48 at the front end of the lens ring 48 by an inner circular flange. The O-ring 46S provides a seal between the reflector 42R and the head housing 42.

The reflector 42R has a curved interior having a shape configured to shape the light produced by a light source 43, eg, an LED light source 43, usually centered at the base or at the rear end of the base. It has a reflective surface. The LED 43 is substantially located in the center of the LED circuit board 42L, which has a printed wiring conductor on top for electrically connecting each terminal of the LED 43 to the conductor 220. Each of the conductors 220 has a vent tab 220T at its front end. The vent tab 220T is electrically connected to the conductor of the LED circuit board 42L, for example, by soldering, and has a hole portion that is in line with the hole portion 44H and is close to the rear end portion thereof. ing. This hole is for providing slip ring contact between the outside of the illuminator housing 30 and the extension arm 44 of the illuminator head 40 to form an electrical connection to the Axis pin 37. ..

The LED circuit board 42L may have wide conductors on one or both sides, and may also have solder-filled through holes and / or other thermal conductive features, which may be present. As a result, the thermal conductivity between the front-facing surface of the LED circuit board 42L on which the LED 43 is mounted and the rear-facing surface of the LED circuit board 42L is improved. Contacting the rearward facing surface of the circuit board 42L is a thermal diffusivity 42H having a relatively high thermal conductivity to further assist in removing the heat generated by the LED 43. Further, the reflector 42R may be made of a material having a relatively high thermal conductivity to further assist in removing the heat generated by the LED 43. The fixing means 42F engages with a hole in the rear end of the reflector 42R to attach the LED circuit board 42L and the heat diffuser 42H to the rear surface of the reflector 42R. The rear surfaces of the reflector 42R are preferably generally flat and preferably in close contact with each other. At the interface between the LED circuit board 42L, the heat diffuser 42H, and the rear surface of the reflector 42R, for example, thermal grease, silicone, or other material to improve the thermal conductivity between them. Materials such as may be included.

With the circuit board 42L and the thermal diffuser 42H attached to the rear end of the reflector 42R and the lens ring 48 and lens 46 attached to the front end of the reflector 42R, the reflector 42R is of the conductor 220. The holes are inserted into the internal cavity of the head housing 42 in a state of being aligned with the respective holes 44H of the arm 44, and are also held in the internal cavity by the additional fixing means 42F2. The additional fixing means 42F2 passes through the holes in the circuit board 42L and the heat diffuser 42H, engages the holes in the rear surface of the reflector 42R, pulls the reflector 42R into the housing 42, and reflects. The vessel 42R is held in the housing 42. Optionally, the O-ring may be provided on each fixing means 42F2 as a seal.

Further details of the electrical connection of the slip ring of the swivel shaft 36 can be seen in the cross section. Here, each of the pivot pins 37 formed at the end of the shaft, for example, a metal pin 37, is inside the housing 30 so as to hold the pivot pin 37 in the swivel shaft 36, while the electric circuit board. Provided is an electrical connection between the conductor 202 connected to the 200 and the conductor 220 connected to the LED circuit board 42L. Also seen in the cross-sectional view are the arrangement of the contact ring 30R on the rear end of the housing 30 and the formation of the connection of the tail cap 24 with the contact spring 24S.

Specifically, the side sectional view shows the circuit board 200, the switch 208 on the circuit board 200, the position of the switch 208 with respect to the flexible cover 22C and the plunger 22P of the actuator 22, and an optical element, for example, a reflector. The internal configuration of the LEDs L1 and L2 on the circuit board 200 with respect to the 26R and the lens 26 in the housing 30 is shown. Preferably, the switch 208 and its actuator are adjacent to the plunger 22P and cover 22C and in a central position under the plunger 22P and cover 22C. It is also visible when the Hall effect sensor HS and the magnet 40M are relatively tightly aligned, when the illuminator head 40 turns to a forward rotation position, and when the illuminator head The positions of the Hall effect sensor or detector HS on the circuit board 200 and the magnets 40M on the rear wall of the illuminator head 40 when the unit 40 is rotated upward by about 90 degrees. And their relative positions. These features are described below. The configuration of the mounting bracket 60 mounted on the clip 50 is also visible in some figures and is described below.

6A and 6C are cross-sectional views of the exemplary luminaires of FIGS. 1A-1D showing exemplary embodiments of the features of the safety luminaire of the luminaire, with FIGS. 6B and 6D being the luminaires, respectively. It is an enlarged view of the details. The light generated by the LED 43 of the illuminator head 40 is directed in front of the illuminator head 40, generally along the longitudinal axis 16, and the illuminator head 40 is swiveled around a hinge or swivel shaft 36. At that time, it is raised to about ± 90 degrees with respect to the longitudinal axis 16. Further, this light is preferably a relatively high-intensity, relatively thin beam, for example, a spot beam, for generating irradiation light directed forward and in the direction in which the illuminator head 40 turns. is there. Further, the second light sources L1 and L2 are generated rearward, generally backwards, through an optical element, such as a lens 26, and as defined by, for example, the longitudinal axis 16.

Such backward-facing light is often generated to be a safety illuminator or safety beacon, thereby allowing a person behind the user of the illuminator 10 to see the safety beacon. The position of the user can be specified. Common uses for such safety beacons are to respond first to firefighters and emergencies when it is difficult to find such users due to smoke, haze, fog, and / or darkness. It is for others to do. For firefighter users, safety beacons are often a blue light. The reason for this is that blue is identifiable from the light produced by fire, which is largely at the edges of the yellow and red visible spectra. For other users, other colors of the safety beacon illuminator may be generated. This color is, for example, red if a color that does not interfere with night vision is desired, or only trackers with night vision equipment, such as strategic military personnel, can see the safety beacon. Is even infrared (IR) light, if desired.

For this reason, the illuminator 10 includes a light source that produces light of two different colors and / or intensities, and an optical element that directs the light backwards. In one exemplary embodiment, the illuminator 10 has a light source L1. The light source L1 is a method in which the light LB1 generated by the light source L1 is directed rearward toward the lens 26, and the light of the safety beacon is emitted in a direction generally rearward through the lens 26. It is mounted on the circuit board 200. The light source L1 is preferably an LED L1 packaged such that when mounted on the circuit board 200, its light LB1 is directed in a direction generally parallel to the surface on which the light source L1 is mounted. .. Most of this light passes through a space defined internally and onto the generally parabolic semireflector 26R, on the reflecting surface 26RS of the reflector 26R in order to deform the beam so that it is incident on the lens 26. The light from the LED L1 that goes unreliably but is incident on the reflective surface 26RS tends to be directed at the lens 26.

The lens portion of the lens 26 is D-shaped, eg, substantially semicircular, and has a series of concentric, partially annular grooves 26G, eg, on its inner surface. This inner surface scatters a beam of light produced by the LED L1 into a relatively well defined but wide light beam LB1 so that the safety beacon is at an angle behind the illuminator 10. It serves to ensure that the light converges to be visible over a relatively wide range. For this reason, the safety beacon LB1 is preferably, for example, basically a beam that is relatively radial rather than a narrow spot beam (as is the light beam LB2).

The annular groove 26G of the lens 26 serves to widen the respective light beams LB1 and LB2 from the LEDs L1 and L2, preferably forming a Fresnel lens or at least approximating a portion of the Fresnel lens. , It is arcuate in the horizontal direction. The partially annular groove 26G has a groove on one side or an arcuate surface, eg, an upward facing side or an arcuate surface, that is substantially perpendicular to a relatively steep slope, eg, the plane of the lens 26. Yes, on the other hand, the point where the other side or the annular surface, eg, the downward facing side or the annular surface, is tilted at an angle, eg, at various angles over a range of angles of about 40 to 50 degrees. Therefore, preferably, the cross section may be serrated, and the light passing through the lens 26 may be slightly concave so as to disperse and form desired beams LB1 and LB2.

The reflector 26R has a substantially semi-circular opening, eg, a D-shaped opening, at its wide end, and also has other curves that are semi-parabolic or less than circular. It may be referred to as a "semi-reflector" in terms of having a substantially defined reflecting surface 26RS. This configuration is interpreted to be spatially more efficient when used with a suitable light source and to ensure much of the high intensity light emitted by the LEDs. The reflector 26R also has a semi-cylindrical protrusion in the front and behind it, for example, when installed in the housing 30. The protrusion fits into the lens 26, the circuit board 200, and a complementary recess in the housing 30 for holding the reflector 26R in the desired position and orientation with respect to the LEDs L1 and L2 on the circuit board 200. ..

The second light source also preferably includes, for example, a second LED L2 mounted on the surface of the circuit board 200. In this mounting position, the second LED L2 is substantially at or near the focal point of the parabola 26RS', the reflective surface 26RS defining in part. The LED L2 produces light that is generally directed away from the circuit board 200 so that it is primarily incident on the reflective surface 26RS of the reflector 26R. The reflecting surface 26RS'is configured to receive the light emitted from the light source LED L2 and form the light into a beam. This beam, for example, when the illuminator 10 is held in the hand or mounted on the front side of a person, passes through the lens 26 rearward toward the lens 26 as a path for illuminating the radial beam. Is aimed at.

Preferably, the reflective surface 26RS of the reflector 26L defines a parabolic portion within the reflector 26R that has a focal point or convergence point on its surface outside of space, thereby adjacent to the reflector 26R on the circuit board. A light source mounted on the 200, such as an LED L2, emits light from a position substantially at or proximal to the convergence point of the parabolic reflective surface 26RS. The parabola is more fully illustrated by the surface 26RS and the dashed line 26RS', where the surface 26RS is part of the parabola 26RS' that forms the reflective surface of the reflector 26R. The reflector 26R has an opening near the base thereof, and the light generated by the LED L1 passes through the opening toward the lens 26.

The lens 26 can be held onto the housing 30 by any suitable fixing means, such as friction fitting, adhesives, ultrasonic welding and the like. Similarly, the reflector 26R can be held in its recess of the housing 30 by any suitable fixing means, such as friction fitting, adhesive, ultrasonic welding and the like.

In one exemplary embodiment, the safety beacon light source LED L1 produces blue light and at least operates when the illuminator head 40 produces irradiation light, but the light source 43 of the illuminator head 40. And the second light sources L1 and L2 may be individually controlled, programmed, and / or actuated, for example, by a modification of the pressing and releasing actuator 22. The internal light source LED L2 produces white light and the illuminator head 40 is preferably away from the clip 50 in a range of 90 degrees or less by a substantial angle, as shown in FIG. 6C. It may be activated when turning.

Preferably, the turning of the lighting device head 40 allows the light generating elements L1 and / or L2 to be activated and / or stopped at a predetermined turning angle. A predetermined angle, which does not need to be particularly accurate, responds to the strength of the magnet 40M, the relative position of the magnet 40M to the Hall effect detector HS, and the sensitivity of the detector HS. The strength of the magnet 40M, the relative position of the magnet 40M to the Hall effect detector HS, and the sensitivity of the detector HS each obtain such actuation and / or deactivation at a particular or desired angle. Can be adjusted at any time. A predetermined angle of turning between about 60 degrees and about 90 degrees is currently considered desirable.

When the illuminator head 40 is so arranged, the magnet 40M in the illuminator head 40 faces (ie, is sufficiently close) to the Hall effect sensor HS on the circuit board 200 in the housing 30. Therefore, for example, the magnetic field of the magnet 40M, as indicated by the field line MFL, acts on the Hall effect sensor HS. When the Hall effect sensor HS detects that such a magnetic field exceeds a predetermined threshold, the Hall effect sensor HS energizes the controller on the circuit board 200 to energize the white light source LED L2 and the blue light source LED L1. Responds to stop energization. When the illuminator head 40 turns away from its rotational position, the strength of the magnetic field in the Hall effect sensor HS is reduced until it falls below the detection threshold of the Hall effect sensor HS, on which the controller uses a white light source. The energization of the LED L2 is stopped, and the energization of the blue light source LED L1 is energized.

The above-mentioned feature is that the illuminating device head 40 is located at the top end of the illuminating device 10 and the tail cap 24 is located at the bottom of the illuminating device 10 by rotating 90 degrees counterclockwise so that the longitudinal axis 16 is vertical. It can be better understood by looking at FIG. 6C, which is located at the end. A person using the illuminating device 10 in this position either grips the housing 30 by hand or uses a clip 50 to attach the illuminating device 10 to himself. For example, the luminaire 10 is attached to the person's clothing or other clothing or equipment. In this orientation, the light generated by the illuminator head 40 is directed forward. For example, it is directed to the person's workplace or forward where the person may move. In addition, the white radial beam generated by the LED L2 and exiting through the lens 26 is directed directly downwards, thereby illuminating the path just in front of the person, thereby over the obstacle. It reduces the chances of passing through or getting into a hole.

Thus, the luminaire 10 has a role in which the luminaire 10 serves at least two different purposes and conditions, eg, as a light and safety light worn on a helmet, and secondly, worn on the body or by hand. It contains features that allow it to act as a flashlight. Further, changing the luminaire 10 from one purpose to the other is due to the fact that the luminaire 10 can be easily mounted and disengaged by engaging and disengaging the clip 50 with the mounting bracket 60. Be promoted. Further convenience is provided because the mounting bracket 60 can remain mounted on the helmet or other object while the luminaire 10 is removed and used for another purpose.

7A and 7B are perspective views showing an exemplary embodiment of a clamp bracket 60 attached to an exemplary clip 50 of an exemplary illuminator 10 of FIGS. 1A to 1D, respectively. 7C and 7D are enlarged views of an exemplary embodiment of the clamp bracket 60. 7E and 7F are perspective views of the clamp bracket 60 attached to the clip 50. FIG. 7G is a plan view of the exemplary clamp bracket 60. If the mounting bracket 60 or other accessory is permanently attached to the luminaire, the use of such luminaire may be restricted.

The illuminating device 10 avoids such restrictions by, for example, configuring the elongated clip 50 of the illuminating device 10 to receive a plurality of different accessories that are attachable and removable to the illuminating device 10. The reason for this is that a variety of different accessories utilize a common mounting configuration, thereby being interchangeable and interchangeable with each other. An example of a method in which such an accessory and the accessory and other accessories can be attached to and removed from the elongated clip 50 of the illuminating device 10 is described here. On the other hand, other examples are described below.

One example of such an accessory is a mounting bracket 60 that can be easily attached to and removed from the clip 50. The clip 50 includes an elongated clip arm 52 that is rotatable around the housing 30 and the longitudinal axis 16 to at least a limited range and preferably extends substantially parallel to the outer surface of the illuminator housing 30. .. The elongated clip arm 52 has a relatively thin portion 52N at its distal end and a relatively wide portion 52B in its central region. The distal end 52N of the clip arm 50 is formed to bend towards the housing 30, thereby providing a firmer clip motion, eg, on a belt or pocket, again. There may optionally be an opening into which a lanyard, rubber ring, clip, or other accessory can be attached.

The mounting bracket 60 includes a C-shaped clamp member 62. The clamp member 62 can be inserted with an object to which the mounting bracket 60 will be attached, such as a firefighter's helmet, a stiff hat, or the edge of another headgear, tool container or other work accessory. .. Such edges are clamped within the clamp member 62 by tightening a clamp fixing means 63, eg, a pair of screws 63 of one or more, to clamp the edges between the clamp anvil 62A and the fixing means 63. Is held in. The mounting bracket 60 defines a base 64 at the end of the clamp member 62 distal to the clamp fixing means 63 and also includes a pair of separated bracket arms 66 extending upward from the base 64. The bracket arms 66 define an opening between them, and the opposing inner surfaces of each bracket arm 66 have an internal groove 67 in the longitudinal direction, eg, in a direction substantially parallel to the base 64. doing.

The opposing grooves 67 are sized and spaced so that the relatively wide portion 52B of the clip arm 52 of the clip 50 is held internally, and the opposing inner surfaces of the bracket arm 66 are relatively wide of the clip arm 52. The clip arm 52 is separated by a distance that is shorter than the width of the portion 52B but larger than the width of the relatively narrow portion 52N of the clip arm 52, so that the narrow portion 52N passes between them. As a result, the bracket 60 can slip onto the clip arm 52 and be held by the clip arm 52, eg, the relatively wide portion 52B of the clip arm 52, and can be easily removed from the clip arm 52. .. Thus, the luminaire 10 can be easily converted from a hand-held or clip-held luminaire to a bracket-held luminaire, and again, the bracket-held luminaire. The device can be easily converted to a hand-held or clip-held luminaire.

Friction between the bracket 60 and the clip arm 52 and / or the luminaire housing 30 limits longitudinal movement in many applications and also places the bracket 60 on the clip arm 52, eg, the clip arm 52. While sufficient to hold on the base 64 of the upper bracket 60, the illuminator housing 30 and the bracket 60 may or may preferably have complementary features that engage more actively. is there. In one example, the surface of the bracket arm 66 that abuts on the housing 30 can be bent to substantially match the curvature of the housing 30, thereby friction between the surface of the bracket arm 66 and the housing 30. Is designed to increase.

Further, the surface of the bracket arm 66 in contact with the housing 30 can be curved and can have one or more ridges and / or grooves 65. The one or more ridges and / or grooves 65 are of a size and shape complementary to the ridges and / or grooves 32 around the housing 30, thereby engaging the respective ridges and / or grooves. Thus, the movement of the bracket 60 in the longitudinal direction with respect to the luminaire housing 30 is explicitly restricted. In all of the above alternatives, the elastic properties of the clip 50, which tends to urge the thinner end 52N towards the housing 30, preferably abut on the housing 30, further clip the bracket 62 to the clip 50. Holding on and keeping such features engaged if the bracket 60 and housing 30 have complementary grooves and / or ridges 26, 65 that engage. Helps.

Since the illuminator 10 has a clip 50 that is rotatable around the longitudinal axis 16 and the housing 30, and also has a illuminator head 40 that is widely rotatable with respect to the housing 30, the user The luminaire 10 has two freedoms of movement relating to directing the light generated from the luminaire head 40 when the luminaire 10 is attached to an object, such as a helmet or its person, clothing or equipment. It allows light to be directed over a wider range than a luminaire, which is fixedly mounted or offers only one degree of freedom of movement.

FIG. 8 is a schematic representation of an exemplary embodiment of an electronic circuit 300 suitable for use in the exemplary luminaire 10 of FIGS. 1A to 1D, which is referenced below. The electrical circuit 300 receives power at the connections M2 (B +) and M3 (B−) provided via the physical elements 202 and 24S, 210, respectively, where the power source is, for example, , A battery that provides voltage VBATT. The circuit 300 is arranged on the circuit board 200. For example, the LED 43 is preferably arranged in the lighting device head portion 40, and the circuit board 200 and the circuit 300 on the circuit board 200 have their respective physics. It is electrically connected by the target conductors 204 and 220.

The operation of the illuminator 10, including the light sources such as LEDs 43, L1 and L2, is controlled by controllers 320, U5, or microprocessors 320, U5. The controller 320, U5, or the microprocessors 320, U5 respond to a signal generated by the switch circuit 350 when the contact S1 of the electrical switch 208 opens and closes. Preferably, the processor 320, U5, or the controllers 320, U5, controls all the functions of the circuit 300. The main light source LED 43 is connected to the connection portions M4 (LED +) and M5 (LED−) of the circuit board 200 by the conductors 204 and 220, respectively.

The method in which the processor 320 responds to the signal from the switch circuit 350 may depend on the timing. For example, it depends on the number of times the switch is closed and / or opened in a given period of time, and / or how long the switch is closed. Such signaling schemes can be employed to generate various modes of operation or states. Various operating modes or states include, for example, off, continuous on and / or temporary on for each LED or combination of LEDs 43, L1, and L2, and, for example, any of LEDs 43, L1, and L2. Alternatively, there is a fixed time for the combination of LEDs 43, L1, and L2, white and / or non-white, flash, blinking, strobe, "Hi-Bright" (above normal brightness level). Includes duration of on and / or operating modes or states for other desired modes. When the "high brightness" feature is provided, the "high brightness" feature is because using the "high brightness" feature usually raises the drain of the battery and shortens the operating time. For example, it can be implemented as a temporary feature that is accessed by holding the actuator 22 pressed for a period of time for which a higher brightness light output is desired.

To energize the light source LED 43, the processor 320 allows the current adjusting DC converter circuit 310 to reduce the voltage VBATT to a voltage VBUCK where the current flowing through the LED 43 is at a predetermined level. The integrated circuit U1 controls the operation of the DC converter 310. The DC converter 310 is, for example, a pulse width modulated back converter having an inductor L1 and a capacitor C5 generated at its internal switch output pin SW to filter voltage pulses with a voltage close to VBATT. Feedback for detecting the current flowing through the LED 43 is provided by the resistor R6. The resistor R6 is directly proportional to the current of the LED 43 and also generates a feedback voltage VFB coupled to the feedback input VFB of the processor 320 via the resistor R5. The AN input that affects the whitening of the LED 43 can be added via the resistor R4.

The current levels of the various predetermined LEDs 43 can be selected by applying various control signals to the processor 320 to the voltage divider, including the resistors R4, R5, and the filtering capacitor C7, for example via DIMMING at the connection. is there. The signal applied at the connection DIMMING (or to another node in the feedback voltage divider) can be adopted to dimming or not dimming the light produced by the LED43 and / or through the LED43. Can be used to increase the flowing current above the normal "high brightness" level of light output.

When enabled and controlled by the CHARGE_PUMP_ENABLE signal, the current regulator circuit 330 receives the output of the voltage VBUCK from the DC converter 310 and also determines the current flowing through the LED L1, for example the blue safety light LED. Includes a charge pump type DC converter U4 configured to generate a voltage of, for example, about +5 VDC to control to the level of. When enabled and controlled by the CHARGE_PUMP_ENABLE signal, it is usually the case that the battery voltage VBATT is less than the voltage required to energize the LED L1. When the battery voltage is sufficient, the LED L1 is energized by the battery voltage VBATT. The current flowing through the LEDs L1 and D3 is controlled by the FET control transistor Q2-1 which bears the signal TAILLIGHT. The resistor R12 provides a voltage feedback signal proportional to the current in the LED L1 via the resistor R13 and the connection I_TAILLIGHT. The current of LED1 is controlled by the signal TAILLIGHT applied to the FET control transistor Q2-1.

For example, an OR circuit provided by a pair of diodes D2, such as a Schottky diode D2, operates for LED L1 from the higher of the battery voltage VBATT and the output voltage VOUT of the charge pump converter U4, for example about +5 VDC. It serves to provide current. Here, the LED L1 is a blue LED that normally requires a higher operating voltage than other LEDs. Normally, the battery voltage is sufficient for the blue LED L1. The voltage VOUT is, for example, about + 5 VDC, and the transistor Q2-1 is controlled by the signal TAILLIGHT from the processors 320, U5 in response to the current feedback signal I_TAILLIGHT, thereby the battery voltage VBATT when the battery is discharged. The LED L1 is adapted to operate at a predetermined current level regardless of whether the power is obtained from either the VBATT or the VOUT from the converter U4, even when the voltage drops.

The current regulator circuit 340 preferably receives power of voltage VBUCK from the DC converter 310 and, when enabled and controlled by the signal DOWNLIGHT, brings the current flowing through the LED L2, eg, the white LED, to a predetermined level. It is configured to control. The resistor R10 provides a voltage feedback signal proportional to the current in the LEDs L2, D1 via the connection I_DOWNLIGHT. The current of the LED L2 is controlled by the FET control transistor Q1. In this exemplary embodiment, no DC converter is required, because the voltage required to operate the relatively low power white LED L2 at the desired predetermined current is, for example, its predetermined current. This is because it is less than the voltage VBUCK required to operate the higher power white LED 43 at the level.

The switch circuit 350 provides a command signal to the processor 320 via the connection MODE_SWITCH. MODE_SWITCH is a relatively low voltage when the contact S1 is closed, for example the GND voltage, and a relatively high voltage when the switch contact S1 is open, for example the voltage of MODE_SWITCH_PULLUP_ENABLE. The contact S1 is opened and closed by pressing and releasing the switch actuator 22 of the lighting device 10.

The head swivel position detection circuit 360 includes a Hall effect sensor HS and a Hall effect detector HS when enabled by the application of an operating voltage in the connection SENSOR_ENABLE. When the Hall effect sensor HS and the Hall effect detector HS are sufficiently swiveled with respect to the lighting device housing 30 so as to raise the magnetic field strength in the Hall effect detector HS to a predetermined level with respect to the lighting device housing 30. When a magnetic field of a predetermined intensity such as a magnetic field generated by the magnet 40M in the lighting device head 40 is received, an output signal is generated in the connection HALL_EFFECT_SENSOR.

Auxiliary output supply circuit 324 produces an operating voltage VDD for processors 320, U5, and other elements of circuit 300.
