The miner's lamp is a general name of a mine lamp or a mine lamp, namely a special lighting lamp used in a mine. Because of different use scenes, the use requirements of the light beams of the miner's lamps are different. For the searching operation, the irradiation range of the miner lamp is required to be as large as possible, and a large enough visual range is ensured; when the mine lamp is used for specific operation, the mine lamp is required to have stronger focusing brightness.
As shown in fig. 1, the present embodiment provides a lamp head that can be used for illumination in a mine. The lamp holder includes top shell 1 and drain pan 2 that can interconnect and sets up the light source subassembly 3 in top shell 1 and the drain pan 2 of connecting, and here is connected including connection methods such as lock and bonding. Specifically, in order to realize the connection between the top shell 1 and the bottom shell 2, a glue groove 101 is formed in the top shell 1, a protrusion 102 is formed in the bottom shell 2, and the top shell 1 is bonded with the bottom shell 2. In other embodiments, the top case 1 may be provided with a protrusion 102, the bottom case 2 may be provided with a glue groove 101, and the top case 1 and the bottom case 2 are adhered to each other. Besides the above scheme, the top shell 1 and the bottom shell 2 can be provided with the glue groove 101 and the protrusion 102, and the top shell 1 is bonded with the bottom shell 2. Compared with the technical scheme of thread assembly of the miner lamp in the prior art, the thread assembly method is characterized in that internal threads are arranged on the top shell 1, and external threads are arranged on the bottom shell 2; or the top shell 1 is provided with an external thread, and the bottom shell 2 is provided with an internal thread, the top shell 1 and the bottom shell 2 of the lamp cap 103 are bonded and sealed through the glue groove 101 to form an integral structure, and the problems of complex assembly structure and high cost in the prior art are solved.
Optionally, in other embodiments, in order to connect the top case 1 and the bottom case 2, the top case 1 and the bottom case 2 may be clamped, for example, if a snap ring is further disposed on the top case 1, a snap protrusion is further disposed on the bottom case 2, and/or a snap protrusion is disposed on the top case 1, a snap ring is disposed on the bottom case 2, and the snap ring is clamped with the snap ring, so that the top case 1 and the bottom case 2 are fixed more firmly. Optionally, in order to ensure the connection reliability between the top shell 1 and the bottom shell 2, in other embodiments, the top shell 1 and the bottom shell 2 are connected while being clamped, that is, the top shell 1 and the bottom shell 2 have a rubber groove protrusion pair and a clamping protrusion snap ring pair at the same time. When the top shell 1 and the bottom shell 2 which are provided with the glue groove protrusion pair and the clamping protrusion snap ring pair simultaneously are installed, glue is coated in the glue groove 101 firstly, then the top shell 1 and the bottom shell 2 are just buckled, the protrusion 102 is bonded on the glue groove 101, the clamping protrusion and the snap ring are clamped simultaneously, and then the assembly of the top shell 1 and the bottom shell 2 is realized.
Optionally, the top case 1 and the bottom case 2 are made of PC + ABS, and the PC + ABS is thermoplastic plastic compounded by Polycarbonate (Polycarbonate) and acrylonitrile-butadiene-styrene copolymer (ABS), and combines excellent characteristics of the two materials, such as moldability of the ABS material and mechanical properties, impact strength, temperature resistance, Ultraviolet (UV) resistance, and the like of the PC.
In order to obtain a large wide angle of illumination, in the prior art, the miner's lamp is usually provided with a light reflecting table right in front of the light source in the light illumination direction, and the top surface of the light reflecting table is opposite to the light source. The light beam emitted by the light source is reflected by the reflecting table and then is diffused in a larger range, so that the wide irradiation angle is enlarged. This scheme is because the existence of reflection of light platform for there is the shadow in the light beam center all the time, has influenced the in-service use effect. In addition, in the prior art, a power mechanism is arranged on the miner lamp and drives and adjusts the light shielding plate in the lamp shell through the power mechanism, so that the irradiation angle of the light shielding plate is enlarged, and the scheme of enlarging the wide irradiation angle is realized; the scheme for driving the light screen in the lamp housing through the power mechanism is complex in structure and high in cost.
Therefore, the embodiment of the invention provides a lamp cap, which uses the annular lens 12 to replace a reflecting table, a power mechanism and a shading plate in the prior art, so as to achieve the effect of enlarging or gathering the irradiated light. The lens 12 and the top shell 1 are integrally formed by injection molding, the cost is low, the structure is simple, and the contradiction between the change of the irradiation wide angle and the existence of beam shadows in the prior technical scheme is solved.
With continued reference to fig. 1, the top case 1 includes a light emitting surface 11, a lens 12 and a top case 13, and the light emitting surface 11, the lens 12 and the top case 13 are integrally injection-molded. The top shell 1 prepared by the method solves the problems of complex assembly structure and high cost of the top shell 1 in the prior art. In addition, the service environment of the miner's lamp is generally worse and more dust is generated. In the use process of the miner lamp, dust easily enters the interior of the miner lamp from the connecting gap of the parts and is accumulated on the inner surfaces of the light-emitting surface 11 and the lens 12, and finally the illumination effect of the miner lamp is influenced, so that light-emitting shadows are caused. The integral injection molding method has better sealing effect, can effectively reduce dust from entering the interior of the miner lamp, and prolongs the service life of the miner lamp. Optionally, the outer surface of the top case 1 is sprayed with a dust-proof paint to further prevent dust accumulation.
In this embodiment, the light emitting surface 11 is a transparent sheet. Optionally, for convenience of manufacturing, the light emitting surface 11, the lens 12 and the top case 13 are made of the same material, and may be made of thermoplastic plastics compounded by Polycarbonate (Polycarbonate) and Acrylonitrile Butadiene Styrene (ABS). The difference is that the light emitting surface 11 and the lens 12 need to be penetrated by the light source, so the color is transparent, and the top case 13 needs to be colored usually, so as to reduce the light source penetrating from the side of the light source 1 and reduce the brightness.
The lens 12 is annular and is disposed between the light emitting surface 11 and the top case 13. It should be noted that the inner and outer edges refer to the inner and outer rims of the ring lens 12, respectively, rather than the inner and outer surfaces of the lens 12. The ring shape of the lens 12 may be a circular ring shape, a square ring shape, a triangular ring shape, or even a special-shaped ring shape, according to different usage scenarios. Further specifically, the lens 12 may be a convex lens or a concave lens, and referring to fig. 1, when the lens 12 is a concave lens, the lens 12 plays a role of divergence, can expand a wide irradiation angle, is suitable for search operation, expands the irradiation range of the miner's lamp, and ensures a sufficiently large visible range; illustratively, as shown in FIG. 1, when no lens is provided, the irradiation angle is 90 °, and by providing a concave lens, the light is diffused outward by the diverging action of the concave lens, and the angle is enlarged by 20 °, so that the wide angle of irradiation of the lamp head is increased to 130 °
As shown in fig. 2, when the lens 12 is a convex lens, the lens 12 has a converging function, can focus light beams, is suitable for specific operations, and ensures that the miner's lamp has strong focusing brightness. The arrangement can ensure that no light-emitting shadow exists on the light-emitting surface 11, and the lens 12 can be used for expanding or converging light beams. Alternatively, the material of the lens 12 generally includes both plastic lens and glass lens, the plastic lens has lower cost and light weight, and the glass lens has higher cost but better imaging effect. In the present embodiment, the material of the lens 12 is a plastic lens.
The light source assembly 3 in this embodiment includes a light source 31, an abutment post 32, a reflective cup 33 and a circuit board 34. The reflector cup 33 is a reflector for condensing and illuminating a point light source, and is generally a cup type, and is commonly referred to as a reflector cup. The materials of the reflector cup generally include: plastic reflective cups, metal reflective cups and glass reflective cups. Optionally, the metal reflective cup in this embodiment is manufactured by stamping and polishing a metal plate, and has moderate cost and good temperature resistance. The bottom of the reflective cup 33 is provided with a through hole, the light source 31 is disposed in the through hole to ensure that the light source 31 can emit light beams toward the light emitting surface 11 and the lens 12, and the light source 31 is disposed coaxially with the lens 12. In detail, in the present embodiment, the axes coaxially arranged are all the central axes 100. The light source 31 and the lens 12 are coaxially arranged, so that light beams emitted by the light source 31 reach the lens 12 more uniformly and symmetrically, and the illumination effect is balanced. Further, the light source 31 and the reflector cup 33 are coaxially disposed, and at this time, the reflector cup 33 and the lens 12 are also coaxially disposed, that is, the lens 12, the light source 31 and the reflector cup 33 are coaxially disposed. Optionally, in this embodiment, the light source 31 selects an LED lamp as the point light source. In the embodiment, the disclosed lamp holder is circular, convenient to carry and good in light condensation effect. Be provided with an LED lamp in the lamp holder, to some occasions that need higher luminance, can set up a plurality of LED lamps, the mode of setting up of a plurality of LED lamps can be the straight line, be the matrix, be the circumference and arrange, wherein be a plurality of LED lamps of circumference and anti-light cup 33 and lens 12 coaxial, guarantee that the light-emitting effect is more even. Further optionally, the light source 31 is electrically connected to the circuit board 34, the circuit board 34 is used to control the on/off, brightness, and the like of the light source 31, and when a plurality of LED lamps are used in the lamp head, a person skilled in the art can control the overall brightness of the lamp head by controlling the on/off of a plurality of LED lamps according to the brightness required by a use scene. The control method is the prior art and is not described herein again.
Specifically, as shown in fig. 2-3, in order to connect the reflective cup 33 and the circuit board 34, a trapezoidal fastener 331 is disposed at the bottom of the reflective cup 33, a mounting hole (not shown) is disposed on the circuit board 34, and the trapezoidal fastener 331 can be fastened in the mounting hole. The arrangement improves the connection stability of the circuit board 34 and the reflection cup 33, thereby ensuring the central polymerization degree of the light source 31 and the reflection cup 33 and improving the light-emitting effect. Trapezoidal buckle 331 is provided with a plurality ofly, and a plurality of trapezoidal buckles 331 evenly set up along anti-light cup 33 circumference, and the joint is more stable. Preferably, as shown in fig. 4, the reflective cup 33 is further provided with a hollow hole 332, and the hollow hole 332 is located outside the trapezoidal fastener 331 and is arranged in one-to-one correspondence with the trapezoidal fastener 331. The hollow hole 332 can provide a deformation space for the trapezoidal buckle 331, which is beneficial to elastic deformation and restoration when the trapezoidal buckle 331 is clamped with the circuit board 34.
A gap is designed between the open end of the reflector cup 33 and the light-emitting surface 11, and the gap can ensure that the light beam emitted from the light source 31 can pass through the gap to irradiate the lens 12 and cover the whole area of the lens 12 and the light-emitting surface 11. The lens 12 can function as a condenser or diffuser to achieve the effect of enlarging the wide angle of illumination or focusing the beam. Specifically, a part of the light beam emitted by the light source 31 directly irradiates the outside of the lamp through the light exit surface 11, and another part of the light beam irradiates the reflective cup 33, and after the first reflection of the reflective cup 33, the light beam is emitted to the light exit surface 11 and the lens 12. After this process, part of the light beam will be reflected by the lens 12 to the reflective cup 33 for the second time, and at this time, the reflective cup 33 performs three reflections, so as to ensure that most of the energy of the light source 31 is irradiated to the outside of the lamp.
Further, since the temperature inside the lamp is increased and maintained at a high temperature when the light source 31 emits light, the circuit board 34 further includes a heat dissipation member, which can enhance the heat dissipation effect of the light source assembly 3 and improve the reliability of the product. Alternatively, the heat sink may be a fan, a heat sink, or a heat sink coating applied directly to the circuit board 34.
In order to fix the light source assembly 3 in the top case 1 and the bottom case 2, the lower portion of the light source assembly 3 is connected to the top case 1 or the bottom case 2 (the connection structure is not shown in the figure), so that the light source assembly 3 is limited to move towards the direction close to the bottom case 2, and the connection mode is not limited here. Illustratively, the lower side of the light source assembly 3 may abut against the top case 1 or the bottom case 2 through the abutment post 32. Or top shell 1 or drain pan 2 are equipped with the spread groove again, and light source subassembly 3 inserts and is connected with top shell 1 or drain pan 2 in the spread groove. Illustratively, in the present embodiment, the light source assemblies 3 are connected to the bottom case 2 through the circuit board 34. It should be noted that, when the heat dissipation member is a heat dissipation plate, the circuit board 34 may be connected to the bottom chassis 2 through the heat dissipation plate, so as to dissipate heat while achieving the installation. Three possible embodiments have been listed so far, and the rest of the more embodiments are not listed.
With continued reference to fig. 2 and 3, in order to further limit the movement of the light source assembly 3 toward the top case 1, when the top case 1 is locked on the bottom case 2, the light source assembly 3 is also abutted against the top case 1. In this embodiment, for realizing the butt of light source subassembly 3 and top shell 1, be equipped with at least three butt post 32 on the light source subassembly 3, butt post 32 and top shell 1 butt to better fixed light source subassembly 3 makes the light source 31 light-emitting on the light source subassembly 3 more steady. Preferably, the abutment post 32 is designed as a rigid cylinder of transparent material, the shape of which is not particularly limited, but the minimum width of the radial cross section of the cylinder is generally greater than the thickness of the reflector cup 33 to ensure the abutment strength. The abutting column 32 is made of transparent materials and is integrally injection-molded with the reflection cup 33, and the structure is simple. This arrangement ensures that the abutment post 32 does not interfere with the beam emitted by the light source 31 and the reflected beam from the lens 12 and does not form an illumination shadow.
As shown in fig. 5, in the second embodiment, a stepped surface 131 facing the bottom case 2 is provided on the inner side of the top case 13. Light source subassembly 3 and step face 131 butt to restriction light source subassembly 3 removes to the direction that is close to top shell 1, better fixed light source subassembly 3, thereby make the light source 31 light-emitting on the light source subassembly 3 steady more and have sufficient light-emitting distance. Preferably, the light reflecting cup 33 in the light source assembly 3 abuts against the stepped surface 131. Compared with the previous embodiment, the light emitting effect of the embodiment is better because the interference of the abutting column to the light is reduced.
As shown in fig. 6, in the third embodiment, the protruding ring 132 is disposed on the inner side of the top housing 13, and the light source assembly 3 abuts against one surface of the protruding ring 132 close to the bottom housing 2 to limit the light source assembly 3 to move toward the direction close to the top housing 1, so as to better fix the light source assembly 3, and thus the light emitted from the light source 31 on the light source assembly 3 is more stable. Preferably, the light reflecting cup 33 in the light source assembly 3 abuts against a surface of the convex ring 132 close to the bottom case 2. In a similar way, compared with the first embodiment, the light emitting effect of the embodiment is relatively better because the interference of the abutting column to the light is reduced.
It should be noted that the light source assembly 3 and the top case 1 are both abutted by the opening side of the reflective cup 33 and the top case 1. Specifically, an outwardly extending tray body is disposed on one side of the opening of the reflective cup 33, the tray body is perpendicular to the top housing 13, and the abutment column 32 is vertically disposed on the tray body. In the second embodiment, the disc body of the reflective cup 33 abuts against the stepped surface 131; in the third embodiment, the disc body of the reflective cup 33 abuts against the convex ring 132.
The lamp holder mounting process is as follows: the circuit board 34 is provided with the light source 31, and the light reflecting cup 33 is clamped with the circuit board 34 through the trapezoidal buckle 331 after the light source 31 is arranged in the through hole. With circuit board 34 through the radiating piece butt in drain pan 2, then connect top shell 1 and drain pan 2 to make anti-light cup 33 and top shell 1 butt, guarantee that light source subassembly 3 is fixed in the inner space of top shell 1 and drain pan 2. The lens 12, the light source 31 and the reflecting cup 33 after being installed are coaxial, and therefore stable and uniform light emitting of the lamp cap is guaranteed.
