[Light-emitting module] 

The light emitting module 10 is, for example, an LED module that emits predetermined light, and is disposed in the inner space of the glove 30 . The light emitting module 10 emits light based on a detection signal from the sensor unit 80 . the

As shown in FIGS. 2 and 3 , the light emitting module 10 in this embodiment includes: a mounting substrate 11 , a plurality of semiconductor light emitting elements 12 mounted on the mounting substrate 11 , and a plurality of semiconductor light emitting elements 12 disposed on the The package 13 on the substrate 11 is mounted. the

The mounting substrate 11 is, for example, a ceramic substrate made of alumina or the like. The mounting substrate 11 in the present embodiment is a substantially annular substrate having a substantially circular hole in the center, and has a tongue portion 14 extending from one position on the inner peripheral edge of the hole toward the center of the hole. the

The front end of the tongue portion 14 is provided with a connector 15 connected to the electrical connection wiring 40a and 40b of the circuit unit 40. By connecting the electrical connection wiring 40a and 40b to the connector 15, the light emitting module 10 and the circuit unit 40 are electrically connected. connect.

Each of the plurality of semiconductor light emitting elements 12 is mounted with a main emission direction facing forward of the light source for illumination. In addition, the semiconductor light emitting element 12 may not be an LED, and for example, a semiconductor laser, an organic EL element, or an inorganic EL element may be used. the

The semiconductor light emitting element 12 is provided so as to surround the insulating case 50. In this embodiment, as shown in FIG. More specifically, two semiconductor light emitting elements 12 arranged in the radial direction of the mounting substrate 11 are arranged in a ring shape at equal intervals along the circumferential direction of the mounting substrate 11 . The semiconductor light emitting elements 12 are sealed in a group unit by a substantially rectangular parallelepiped-shaped package 13 . Therefore, in this embodiment, there are 16 packages 13 in total. The longitudinal direction of each package 13 coincides with the radial direction of the mounting substrate 11, and each package 13 is radially arranged around the lamp axis J when viewed from the front side along the lamp axis J (planar view). . the

In addition, the number of semiconductor light emitting elements 12 is not limited to a plurality, and may be one. In addition, the posture of the semiconductor light emitting elements 12 does not necessarily have to be such that all of the semiconductor light emitting elements 12 are oriented in the direction along the lamp axis J, and some of them may be tilted with respect to the lamp axis J, and may be placed in the posture of facing the inclined direction. Install. According to this, since it is possible to improve the control performance of the light distribution angle of the lamp, it is possible to perform fine adjustments so as to obtain desired light distribution characteristics. the

The package body 13 is mainly composed of a light-transmitting material. When it is necessary to convert the wavelength of light emitted from the semiconductor light emitting element 12 into a predetermined wavelength, a wavelength conversion material for converting the wavelength of light can be mixed into the Translucent material. As the translucent material, for example, silicone resin can be used. In addition, phosphor particles can be used as the wavelength conversion material, for example. Accordingly, the package body 13 can be configured as a phosphor-containing resin. the

In this embodiment, as the semiconductor light-emitting element 12, a blue LED that emits blue light is used, and as the package 13, phosphor particles that convert the wavelength of blue light into yellow light and a light-transmitting LED in which the phosphor particles are mixed are used. permanent resin material. Accordingly, part of the blue light emitted from the semiconductor light emitting element 12 is wavelength-converted into yellow light by the package body 13, and the wavelength-converted yellow light is mixed with the unconverted blue light to generate white light, which is emitted from the light emitting module 10. . the

Furthermore, the light-emitting module 10 can also be realized, for example, by combining a semiconductor light-emitting element that emits ultraviolet rays and phosphor particles of each color that emit light of three primary colors (red, green, and blue). Furthermore, as the wavelength converting material, a material containing a substance capable of absorbing light of a certain wavelength and emitting light of a wavelength different from the absorbed light, such as a semiconductor, a metal complex, an organic dye, or a pigment, may be used. the

[Abutment]

The base 20 is a light source mounting member for mounting the light emitting module 10 . The light-emitting module 10 is disposed on the front surface of the base 20 and fixed to the base 20 by, for example, fixing members, screws, adhesive, or the like. the

The base 20 in this embodiment has a through-hole 20a, has a generally thin cylindrical shape, and is arranged in a posture in which the cylinder axis coincides with the lamp axis J. As shown in FIG. In addition, the light emitting module 10 is placed on the front surface of the base 20 with the main emission direction of each of the semiconductor light emitting elements 12 facing forward. Since the through-hole 20a is provided in the base 20, the weight of the light source 1 for illumination can be reduced. Furthermore, since a part of the circuit unit 40 is arranged in the through hole 20 a and in the glove 30 via the through hole 20 a, the light source 1 for illumination can be downsized. the

Furthermore, the base 20 in the present embodiment is made of, for example, a metal material. As the metal material, for example, Al, Ag, Au, Ni, Rh, Pd, or an alloy composed of two or more of these metal materials, or an alloy of Cu and Ag, etc. are conceivable. Since these metal materials have good thermal conductivity, heat generated in the light emitting module 10 can be efficiently conducted to the housing 60 . For example, the base 20 can be formed into a substantially disk-shaped metal substrate by aluminum die-casting. In this way, by constituting the base 20 with a metal material, the base 20 can function as a radiator that conducts heat generated by the light emitting module 10 to the housing 60 . the

[Dome cover]

The dome cover 30 is a hemispherical translucent cover for emitting light emitted from the light emitting module 10 to the outside of the lamp.

Cover side opening. the

In addition, it is preferable that the globe cover 30 is subjected to diffusion treatment so as to diffuse the light emitted from the light emitting module 10 . For example, the glove 30 can have a light-diffusing function by forming a light-diffusing film (light-diffusing layer) on the inner surface or the outer surface of the glove 30 . Specifically, the light-diffusing film is formed by coating the entire inner or outer surface of the glove 30 with a resin containing a light-diffusing material such as silica or calcium carbonate, or a white pigment. Alternatively, the glove 30 may have a light-diffusing function by forming light-diffusing dots on the glove 30 . For example, by processing the surface of the resin glove 30 to form a plurality of dots, minute depressions (dimples) can be formed so that the glove 30 can have a light diffusion function. In addition, the spherical cover 30 may be provided with a light-diffusing function by performing surface texture processing. the

In this way, by giving the glove 30 a light diffusing function, the light incident on the glove 30 from the light emitting module 10 can be diffused, and thus the light distribution angle of the light source for illumination can be enlarged. the

In addition, in this embodiment, it is not limited to the shape imitating the A-type light bulb, and other shapes may be used. For example, the shape of the spherical cap 30 may be a spheroid or a partial spheroid. Furthermore, as the material of the glove 30, resin materials such as glass material and synthetic resin can be used, and the glove 30 is formed of polycarbonate in the present embodiment. the

The circuit board 41 is arranged with its principal surface parallel to the lamp axis J. As shown in FIG. In this way, the circuit unit 40 can be accommodated in a small space in the insulating case 50 . Furthermore, in the circuit unit 40 , electronic components with poor heat resistance are arranged at a position away from the light emitting module 10 , and electronic components with high heat resistance are arranged at a position close to the light emitting module 10 . In this way, it is possible to reduce destruction of electronic components having poor heat resistance by heat generated by the light emitting module 10 . the

The circuit unit 40 and the base 70 are electrically connected by electrical connection wirings (leads) 40c and 40d. The electrical connection wiring 40 c is connected to the case portion 71 of the base 70 through the through hole 50 a provided in the insulating case 50 . The electrical connection wiring 40 d is connected to the contact piece portion 73 of the base 70 through the opening on the base side of the insulating case 50 . the

Specifically, as will be described later, the plate-shaped top portion of the third case portion 53 of the insulating case 50 serves as a partition. the

The insulating case 50 is preferably formed of an insulating material such as resin, for example. In addition, the insulating case 50 preferably functions as a thermal barrier between the sensor unit 80 and the circuit unit 40, and may be made of a material with low thermal conductivity. In this embodiment, the insulating case 50 is made of polybutylene terephthalate (PBT) having a thermal conductivity of about 0.18 to 0.29 (W/m·°C). the

Moreover, the material of the insulating case 50 is not limited to PBT, but may also be polyethylene terephthalate (PET), LCP (liquid crystal polymer), amorphous thermoplastic polyetherimide (ULTEM resin), or polyimide. Other resin materials with high heat-resistant temperature such as imine, etc. the

In addition, the insulating case 50 in this embodiment is composed of a cylindrical first case portion (large diameter portion) 51, a cylindrical second case portion (small diameter portion) 51 having substantially the same shape as the base 70, and a third cylindrical case portion (small diameter portion) 51. The shell portion 53 is constituted, and the third shell portion 53 is a bottomed cylindrical cover member whose globe side is closed and the base side is opened. the

The second case part 52 is provided on the lamp cap side of the first case part 51 , and the lamp cap 70 is externally fitted in the second case part 52 . Accordingly, the opening on the base side of the insulating case 50 is blocked. the

The third case portion 53 is accommodated in the glove 30 and is provided at the end portion of the first case portion 51 on the glove side. The third case portion 53 is composed of a first cover portion whose diameter gradually decreases toward the glove side, and a second cover portion that has a cylindrical shape with the same diameter in the vertical direction. the

The top surface (bottom) of the first cover portion in the third case portion 53 is formed in a circular plate shape and serves as a partition between the sensor portion 80 (mounting board 81 ) and the circuit unit 40 . The sensor unit 80 is spatially separated from the circuit unit 40 by the third case unit 53 (partition plate). In this way, the sensor unit 80 and the circuit unit 40 are arranged so as not to be in contact with each other. the

In addition, the side peripheral surface of the third case portion 53 can function as a light reflection surface. In this case, the light from the light emitting module 10 is reflected by the side peripheral surface of the third case portion 53 and reaches the inner surface of the glove 30 . In this way, the insulating case 50 (third case portion 53 ) can function as a member that adjusts the light distribution characteristics (light distribution angle) of the illumination light source 1 . Furthermore, in order to improve the reflectivity of the third case portion 53 , the surface of the third case portion 53 may be mirror-finished. the

A through hole 50 b is provided at a position corresponding to the tongue portion 14 of the light emitting module 10 on the insulating case 50 .

Therefore, it is possible to suppress conduction of heat generated in the light emitting module 10 to the insulating case 50 . In this way, since the temperature rise of the insulating case 50 can be suppressed, it is possible to suppress the circuit unit 40 from being damaged by heat. the

The base 20 and the opening-side end of the glove 30 are housed in an opening (first opening) on the glove side of the frame 60 , and the frame 60 is fixed to the base 20 by caulking, for example. Furthermore, the frame body 60 can also be fixed to the base 20 by flowing an adhesive into the space 60a surrounded by the frame body 60, the base 20, and the globe cover 30. the

The shape of the outer peripheral edge of the base side end part of the base 20 corresponds to the shape of the inner peripheral surface of the frame body 60, and is tapered. The tapered surface of the base 20 is in surface contact with the inner peripheral surface of the frame 60 , and the heat conducted from the light emitting module 10 to the base 20 can be more easily conducted to the frame 60 . Accordingly, the heat generated in the semiconductor light emitting element 12 is mainly conducted to the lamp base 70 through the base 20 and the frame body 60, and further via the second case portion 52 of the insulating case 50, and then from the lamp base 70 to the lighting fixture (not shown) side.

Accordingly, the frame body 60 functions as a heat sink, and the heat generated by the light emitting module 10 and the circuit unit 40 can be efficiently dissipated to the outside of the illumination light source 1 through the frame body 60 . As the metal material of the frame body 60, for example, Al, Ag, Au, Ni, Rh, Pd, or an alloy composed of two or more of these metals, or an alloy of Cu and Ag may be considered. Since these metal materials have good thermal conductivity, the heat conducted to the frame body 60 can be efficiently transferred to the side of the lamp head. Therefore, the heat generated by the light emitting module 10 and the circuit unit 40 can also be dissipated to the side of the lighting fixture via the base 70 . In this embodiment, the frame body 60 is made of an aluminum alloy material. In addition, in order to increase the heat emissivity of the frame body 60, the surface of the frame body 60 may be treated with an aluminum oxide film. In addition, the material of the frame body 60 is not limited to metal, and may be resin. For example, the frame body 60 can be formed of resin with high thermal conductivity or the like. the

[lamp holder]

The base 70 is a power receiving unit that receives alternating current through two contacts, and is attached to, for example, a lamp socket of a lighting fixture. In this case, when the lighting light source 1 is turned on, the base 70 receives electric power from the socket of the lighting fixture. Then, the electric power received by the base 70 is input to the electric power input part of the circuit unit 40 via the electric connection wirings 40c and 40d. the

The base 70 includes a case portion 71 having a substantially cylindrical shape with a male thread on its outer peripheral surface, and a contact piece portion 73 attached to the case portion 71 via an insulating portion 72 .

In this way, the sensor unit 80 and the circuit unit 40 are spatially separated by the insulating case 50 , and are configured so as not to be in direct contact due to the existence of the insulating case 50 . That is, the sensor unit 80 and the circuit unit 40 are brought into a non-contact state by the insulating case 50 . the

More specifically, the mounting board 81 of the sensor unit 80 and the circuit board 41 of the circuit unit 40 are not in direct contact with each other. the

[Light guide parts]

The light guide member 90 is an optical member for guiding light to the light receiving surface of the sensor body 82 . The light guide member 90 in this embodiment is a convex lens, and is configured to condense infrared rays radiated from a person on a light receiving surface. As the light guide member 90, for example, a Fresnel lens can be used. the

Furthermore, as shown in FIG. 3 , the light guide member 90 is arranged so as to overlap the sensor unit 80 in plan view. That is, the light guide member 90 is arranged above the sensor unit 80 . In addition, the light guide member 90 is arranged such that the lens center axis coincides with the lamp axis J. As shown in FIG. the

In the present embodiment, the light guide member 90 is fitted into an opening provided in the glove 30 and protrudes from the outer surface of the glove 30 . The light guide member 90 can be formed using a translucent material such as glass or resin, and is formed of polyethylene in this embodiment. the

The illumination light source 1 according to Embodiment 1 of the present invention having such a configuration operates as follows. the

First, when a person enters the detection range of the sensor unit 80 when the illumination light source 1 is turned off, the sensor unit 80 (sensor body 82 ) detects infrared rays radiated from the person. Next, the sensor unit 80 (control circuit) outputs a signal indicating that a person has been detected to the circuit unit 40 . The circuit unit 40 having obtained the detection signal from the sensor unit 80 supplies predetermined electric power to the light emitting module 10 . Thereby, the light emitting module 10 emits light, and the light source 1 for illumination becomes a lighting state. In this way, when a person enters the lighting area and the presence of the person is detected by the sensor unit 80, the light source 1 for lighting is automatically turned on. the

In addition, when the illumination light source 1 is turned on, the circuit unit 40 stops supplying power to the light emitting module 10 when the infrared intensity does not change for a certain period of time due to a person coming out of the detection range of the sensor unit 80 . In this way, since the light emitting module 10 is in a non-light emitting state, the light source 1 for illumination is in an off state. In this way, when the sensor unit 80 detects the absence of a human being for a certain period of time, the light source 1 for illumination is automatically turned off. the

In summary, with the light source 1 for illumination according to Embodiment 1 of the present invention, the sensor unit 80 and the circuit unit 40 are arranged in the peripheral without contacting each other, and the sensor unit 80 and the circuit unit 40 become A structure that is not mechanically connected. Specifically, the sensor unit 80 and the circuit unit 40 are spatially separated by a partition that is a part of the insulating case 50 . Accordingly, since the sensor unit 80 is not easily affected by the heat generated by the circuit unit 40 , it is possible to suppress fluctuations in the output of the sensor unit 80 due to heat. Therefore, it is possible to reduce malfunction of the light source 1 for illumination due to fluctuations in the output of the sensor unit 80 . the

(implementation mode 2)

Next, the structure of the light source 2 for illumination which concerns on Embodiment 2 of this invention is demonstrated using FIG. 4. FIG. 4 is a cross-sectional view of a light source for illumination according to Embodiment 2 of the present invention. In addition, the same symbols as in Embodiment 1 are given to the same components as in Embodiment 1. FIG. the

The light source 2 for illumination according to this embodiment differs from the light source 1 for illumination according to Embodiment 1 in the configuration of the light guide member. That is, the light guide member 290 in this embodiment is the same as Embodiment 1 in that it guides light (infrared rays) to the sensor unit 80 , but it is different from Embodiment 1 in that it is formed into a cover shape so as to cover the sensor unit 80 . . the

In the present embodiment, the light guide member 290 is an optical member that has an opening on one side and is closed on the other side. The closed portion of the light guide member 290 is configured to guide light (infrared rays) to the light receiving surface of the sensor body 82 and function as a condensing lens. Furthermore, the opening portion of the light guide member 290 is in contact with the upper surface of the third case portion 53 of the insulating case 50 . the

The light guide member 290 is arranged to cover the entire sensor unit 80 and is fixed to the insulating case 50 . Furthermore, in the present embodiment, the light guide member 290 is arranged such that its central axis coincides with the lamp axis J. As shown in FIG. the

In addition, in this embodiment, a part of the light guide member 290 protrudes from the outer surface of the glove 30 , and the closed portion (lens portion) of the light guide member 290 goes outward from the opening provided in the glove 30 . The protruding form is provided on the insulating case 50 . In addition, the light guide member 290 and the glove 30 have a gap, and are arranged so as not to be in contact with the glove 30 . Accordingly, damage to the glove 30 due to the light guide member 290 during assembly or the like can be suppressed. the

Furthermore, the light guide member 290 can be formed of a light-transmitting material such as glass or resin, as in the first embodiment, and is also formed of polyethylene in this embodiment. Furthermore, as in the first embodiment, a Fresnel lens can be used for the light guide member 290 . In addition, although the light guide member 290 is arranged not to be in contact with the glove 30 , it may be in contact with the glove 30 . the

The illumination light source 2 having such a configuration performs the same operation as that of the illumination light source 1 according to the first embodiment. That is, when a person enters the lighting area, the presence of the person is detected by the sensor part 80, so that the light source 2 (light emitting module 10) for lighting is automatically turned on; After a certain time elapses from the start of existence, the light source 2 for illumination (light emitting module 10 ) is automatically turned off. the

In summary, according to the light source 2 for illumination according to the second embodiment of the present invention, the sensor unit 80 and the circuit unit 40 are spatially separated by the insulating case 50 (partition plate) as in the first embodiment. , are configured in a non-contact state. Accordingly, the sensor unit 80 is not easily affected by the heat generated by the circuit unit 40 . Therefore, it is possible to suppress the fluctuation of the output of the sensor unit 80 due to heat, and to reduce the malfunction of the light source 2 for illumination. the

Furthermore, in the light source 2 for illumination according to the present embodiment, the light guide member 290 is also fixed to the insulating case 50 in addition to the sensor unit 80 . Thereby, the focus shift of the light guide member 290 with respect to the sensor part 80 (sensor main body 82) can be reduced, and the fall of the sensitivity of the sensor part 80 (sensor main body 82) can be suppressed. the

That is, when the sensor unit and the light guide member are respectively fixed at different positions, the sensor unit and the light guide member may deviate from the predetermined positions during the manufacturing process or transportation of the light source for illumination, and the sensitivity of the sensor unit may deteriorate. Lowering the problem. For example, if the light guide member 90 is fixed to the glove 30 as in Embodiment 1, the accuracy of the alignment (focus) between the sensor unit 80 and the light guide member 90 needs to be determined by the positional alignment between the glove 30 and the housing 60 . The alignment of the light guide member 90 and the sensor unit 80 (sensor body 82 ) is difficult to be determined by determining the alignment of the housing 60 and the insulating case 50 . On the other hand, in this embodiment, since the sensor unit 80 and the light guide member 290 are fixed to the insulating case 50, it is easy to align the focus of the light guide member 290 on the sensor unit 80 (sensor body 82), thereby suppressing the The sensitivity of the sensor unit 80 decreases due to the out of focus of the light guide member 290 . the

Furthermore, in the present embodiment, since the light guide member 290 is not fixed to the glove 30 but is fixed to the insulating case 50 , the breakage of the glove 30 can be reduced. the

That is, as in the first embodiment, in the method of mechanically fixing the light guide member 90 to the glove 30 , the glove 30 may be broken when the light guide member 90 is fixed to the glove 30 . In particular, the glove 30 made of polycarbonate material is easily broken, and therefore, when the light guide member 90 is fixed to the glove 30 , the glove 30 is likely to break. On the other hand, in this embodiment, since the light guide member 290 is fixed not to the glove 30 but to the insulating case 50 , it is possible to reduce breakage of the glove 30 when the light guide member 290 is attached. the

Furthermore, in this embodiment, it is preferable that the light guide member 290 contains a thermally conductive substance. In this case, the thermal conductivity of the light guide member 290 as a whole is preferably higher than the thermal conductivity of the mounting substrate 81 of the sensor unit 80 . Accordingly, the heat conducted to the circuit unit 40 of the insulating case 50 is more easily conducted to the side of the light guide member 290 than the sensor unit 80, and therefore, the heat of the circuit unit 40 can be conducted to the light guide member 290 to dissipate heat. To the outside (in the atmosphere) of the light source 1 for illumination. In this way, the sensor unit 80 is less likely to be affected by the heat from the circuit unit 40 , and it is possible to further suppress fluctuations in the output of the sensor unit 80 due to heat. the

(implementation mode 3)

Next, the structure of the light source 3 for illumination which concerns on Embodiment 3 of this invention is demonstrated using FIG. 5. FIG. 5 is a cross-sectional view of a light source for illumination according to Embodiment 3 of the present invention. In addition, the same symbols are assigned to the same components as in Embodiment 1. FIG. the

The light source 3 for illumination according to this embodiment differs from the light source 1 for illumination according to Embodiment 1 in the configuration of the light guide member. That is, light guide member 390 in this embodiment is the same as Embodiment 1 in that it guides light (infrared rays) to sensor unit 80 , and it is different from Embodiment 1 in that it is formed into a cover shape so as to cover sensor unit 80 . the

In the present embodiment, the light guide member 390 is an optical member that has an opening on one side and is closed on the other side, as in the second embodiment. The light guide member 390 is configured such that the closed portion guides light (infrared rays) to the light receiving surface of the sensor body 82 and functions as a condensing lens. Furthermore, the opening portion of the light guide member 390 is in contact with the upper surface of the mounting substrate 81 of the sensor unit 80 . the

The light guide member 390 is arranged to cover the entire sensor unit 80 and is fixed to the mounting substrate 81 of the sensor unit 80 . Moreover, in this embodiment, the light guide member 390 is arranged so that the center axis thereof coincides with the lamp axis J. As shown in FIG. the

In addition, in this embodiment, a part of the light guide member 390 protrudes from the outer surface of the glove 30 , and the light guide member 390 protrudes outward from an opening provided in the glove 30 with its closed portion (lens portion). are disposed on the mounting substrate 81 in a manner. Furthermore, as in Embodiment 2, the light guide member 390 is arranged so as not to be in contact with the glove 30 with a gap left between the glove 30 and the glove 30 . Accordingly, damage to the glove 30 due to the light guide member 390 during assembly can be reduced. the

Furthermore, the light guide member 390 can be formed of a light-transmitting material such as glass or resin, as in the first embodiment, and is also formed of polyethylene in this embodiment. Furthermore, as in the first embodiment, a Fresnel lens can be used for the light guide member 390 . In addition, although the light guide member 390 is arranged not to be in contact with the glove 30 , it may be in contact with the glove 30 . the

The illumination light source 3 having such a configuration performs the same operation as the illumination light sources 1 and 2 according to the first and second embodiments. That is, when a person enters the lighting area, the presence of the person is detected by the sensor part 80, so that the light source 3 (light emitting module 10) for lighting is automatically turned on; After a certain time elapses from the start of existence, the light source 3 for illumination (light emitting module 10 ) is automatically turned off. the

As described above, according to the light source 3 for illumination according to Embodiment 3 of the present invention, similarly to Embodiment 1, the sensor unit 80 and the circuit unit 40 are spatially separated by the insulating case 50 (partition plate), and arranged into a non-contact state. In this way, the sensor unit 80 is not easily affected by the heat generated by the circuit unit 40 . Therefore, fluctuations in the output of the sensor unit 80 due to heat can be suppressed, and malfunction of the light source 3 for illumination can be reduced. the

Furthermore, in the illumination light source 3 according to the present embodiment, the light guide member 390 is fixed to the mounting substrate 81 of the sensor unit 80 . In this way, since the focus misalignment between the light guide member 290 and the sensor unit 80 (sensor body 82 ) can be reduced, it is possible to suppress a decrease in the sensitivity of the sensor unit 80 (sensor body 82 ). the

That is, if the light guide member is fixed at a position different from that of the sensor unit, the sensor unit and the light guide member will deviate from a predetermined position during the manufacturing process or transportation of the light source for illumination, thereby degrading the sensitivity of the sensor unit. For example, when the light guide member 90 is fixed to the glove 30 as in Embodiment 1, the accuracy of the alignment (focus) between the sensor unit 80 and the light guide member 90 needs to be adjusted by the glove 30 and the housing 60 . The alignment position of the light guide member 90 and the alignment position of the frame body 60 and the insulating case 50 are determined, so that it is difficult to align the focus of the light guide member 90 with the sensor unit 80 (sensor body 82 ). In contrast, in this embodiment, since the light guide member 390 is fixed to the mounting substrate 81 of the sensor unit 80 , the focus of the light guide member 390 is easily aligned with the sensor unit 80 (sensor body 82 ). For example, in this embodiment, the positions of the light guide member 390 and the sensor unit 80 can be aligned at the same time as the light guide member 390 is attached. In this way, it is possible to suppress a decrease in the sensitivity of the sensor unit 80 due to out-of-focus of the light guide member 390 . the

Furthermore, in the present embodiment, since the light guide member 390 is not fixed to the glove 30 but is fixed to the sensor unit 80 (mounting board 81 ), the breakage of the glove 30 can be reduced. the

That is, in the method of mechanically fixing the light guide member 90 to the glove 30 as in Embodiment 1, the glove 30 may be broken when the light guide member 90 is fixed to the glove 30 . In particular, the glove 30 made of polycarbonate material is easily broken, and therefore the glove 30 is likely to break when the light guide member 90 is fixed to the glove 30 . On the other hand, in this embodiment, since the light guide member 390 is not fixed to the glove 30, but is fixed to the sensor part 80 (mounting substrate 81), it is possible to reduce the load on the glove 30 when the light guide member 390 is attached. rupture. the

Furthermore, in this embodiment, it is preferable that the light guide member 390 contains a thermally conductive substance. In this case, the thermal conductivity of the light guide member 390 as a whole is preferably higher than the thermal conductivity of the mounting substrate 81 of the sensor unit 80 . Accordingly, the heat conducted to the circuit unit 40 of the mounting substrate 81 of the sensor unit 80 can also be conducted to the light guide member 290 to dissipate heat to the outside of the illumination light source 1 (atmosphere). Therefore, the sensor unit 80 is less likely to receive heat from the circuit unit 40 , and it is possible to further suppress fluctuations in the output of the sensor unit 80 due to heat. the

Furthermore, in the present embodiment, although the light guide member 390 is fixed to the mounting substrate 81 of the sensor unit 80 , it may be fixed to the sensor main body 82 . the

(Implementation 4)

FIG. 6 is a cross-sectional view of a light source for illumination according to Embodiment 4 of the present invention. In addition, the same symbols as in Embodiment 1 are given to the same components as in Embodiment 3. FIG. the

Compared with the light source 3 for illumination according to Embodiment 3, the light source 4 for illumination according to the present embodiment is further provided with a heat dissipation member 490 . the

The heat dissipation member 490 is a member for dissipating heat from the sensor unit 80 , and is provided between the light guide member 390 and the sensor unit 80 . The heat dissipation member 490 can be made of a light-transmitting material containing a thermally conductive substance, and in this embodiment, it is formed by filling a space between the light guide member 390 and the sensor unit 80 with a transparent resin containing a thermally conductive substance. As such a translucent material, polyethylene can be used, for example. As the thermally conductive substance, a material having higher thermal conductivity than the translucent material can be used. the

Furthermore, in the present embodiment, the heat dissipation member 490 is configured to condense light (infrared rays) to the sensor unit 80 together with the light guide member 390 . That is, the heat dissipation member 490 can also function as a light guide member. the

The illumination light source 4 having such a configuration performs the same operation as that of the illumination light source 3 according to the third embodiment. That is, when a person enters the lighting area, the presence of the person is detected by the sensor unit 80, and the light source 4 (light emitting module 10) for lighting is automatically turned on; After a certain period of time has elapsed since the existence of the light source, the light source 4 (light emitting module 10) for illumination is automatically turned off. the

In summary, with the light source 4 for illumination according to the fourth embodiment of the present invention, the same effect as that of the third embodiment can be achieved. That is, according to the present embodiment, the sensor unit 80 and the circuit unit 40 are spatially separated by the insulating case 50 (partition plate), and are arranged in a state where they are not in contact with each other. Accordingly, it is possible to suppress fluctuations in the output of the sensor unit 80 due to heat, and it is possible to reduce malfunction of the light source 4 for illumination. In addition, since the light guide member 390 is fixed to the mounting substrate 81 of the sensor unit 80, it is possible to reduce the deviation of the focus of the light guide member 290 from the sensor unit 80 (sensor main body 82), thereby suppressing the sensor unit 80 (sensor main body 82). decrease in sensitivity. Furthermore, since the light guide member 390 is not fixed to the glove 30 but is fixed to the sensor unit 80 (mounting substrate 81 ), it is possible to reduce the breakage of the glove 30 . the

Moreover, in this embodiment, since the heat dissipation member 490 is provided between the sensor unit 80 and the light guide member 390 , the heat conducted to the circuit unit 40 on the mounting substrate 81 of the sensor unit 80 can be dissipated via the heat dissipation member 490 . The heat is actively dissipated to the outside (in the air) of the light source 1 for illumination. Therefore, the sensor unit 80 is less likely to be affected by heat from the circuit unit 40 , and it is possible to further suppress fluctuations in the output of the sensor unit 80 due to heat. the

Also in this embodiment, the light guide member 390 is fixed to the mounting substrate 81 of the sensor unit 80 in the same manner, but may be fixed to the sensor main body 82 . Furthermore, this embodiment can also be applied to Embodiments 1 and 2. the

As mentioned above, although the light source for illumination which concerns on this invention was demonstrated based on embodiment, this invention is not limited to these embodiment. the

For example, although the light guide member is used in all the above-mentioned embodiments, the light source for illumination may be configured without the light guide member. the

In addition, in the above-described embodiment, a part of the insulating case 50 is used as a partition plate that spatially separates the sensor unit 80 and the circuit unit 40 , but the present invention is not limited thereto. For example, a separate partition may be provided between the sensor unit 80 and the circuit unit 40 regardless of the insulating case 50 . In this case, the separator is preferably made of insulating material with low thermal conductivity. the

In addition, in the above-mentioned embodiment, although the sensor unit 80 is provided in the insulating case 50, the sensor unit 80 may be arranged in the insulating case 50 as long as the sensor unit 80 and the circuit unit 40 are arranged in a state where they are not in contact with each other. outside the location. For example, the sensor unit 80 may be fixed to the housing 60 , or the sensor unit 80 may be disposed between the circuit unit 40 and the housing 60 . In this case, the light guide member may be appropriately provided according to the arrangement position of the sensor unit 80 . the

In addition, in the above-mentioned embodiment, although the light source for illumination of an E-type base was demonstrated, it is not limited to this. For example, the present invention can also be applied to other lamp holders such as GX53 type. the

In addition, in the above-mentioned embodiment, although a COB (Chip On Board: chip on board) type in which an LED chip (bare chip) is mounted on a mounting substrate is used as the LED structure in the light emitting module, it is not limited thereto. For example, the present invention can also be applied to a surface mount (Surface Mounted Device: SMD) type in which an LED chip is packaged to form an LED element, and this LED element is mounted on a mounting substrate. the

Furthermore, the present invention can also be realized as a lighting device including the above-mentioned light source for lighting. For example, the configuration shown in FIG. 7 may be used, and the lighting device 100 according to the present invention includes the above-mentioned lighting light source 1 and a lighting fixture (lighting fixture) 110 to which the lighting light source 1 is attached. In this case, the lighting fixture 110 turns off and turns on the light source 1 for illumination, and includes, for example, a fixture main body 111 attached to the ceiling and a globe 112 covering the light source 1 for illumination. The device main body 111 is attached with the base 70 of the light source 1 for illumination, and has a socket 111 a for supplying power to the light source 1 for illumination. In addition, a light-transmitting plate may be provided at the opening of the globe 112 . the
