Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and specifically relates to a track lamp. Background Technique

[0002] A track lamp is a lighting fixture that can be installed on the ceiling or wall. It mainly installs the track lamp on a fixed guide rail set on the ceiling or wall, so that the track lamp can move on the guide rail. With the development of technology, existing track lamps often ignore the glare problem in order to pursue high luminous flux. If the luminous flux is too high, it means more light output. If the light source is too concentrated or the lamp design is unreasonable at this time, it is very easy to cause serious glare. How to make the track lamp meet the high luminous flux while solving the glare problem, so that the track lamp can achieve both bright and soft and comfortable lighting effects at the same time, is a technical problem that the entire industry needs to solve urgently.

The lens bracket and the plurality of lens bodies are integrally formed. The lens bracket is fixedly connected to the aluminum substrate, and a pair of LED light source groups are correspondingly clamped in one lens body;

[0008] The anti-glare assembly is arranged on the back plate. The anti-glare assembly includes an anti-glare cover and a plurality of anti-glare cups. The anti-glare cover and the plurality of anti-glare cups are integrally formed. The anti-glare cover is fixedly connected to the back plate. One lens body is correspondingly clamped in one anti-glare cup. The anti-glare cup is a cover body surrounded by four inclined surfaces. The outer side of the cover body gradually expands into a trumpet shape. The connection between the inclined surfaces adopts an arc surface design for smooth transition. The inner peripheral surface of the anti-glare cup is provided with a grid optical surface, and each grid surface of the grid optical surface is an outwardly convex curved surface.

[0009] Preferably, a guide groove is provided inside the track, and a plurality of conductive metal wires are embedded in the guide groove.

Both ends of the fixing post are fixedly connected to the housing. A through hole is provided on the fixing post, and the position of the through hole corresponds to the position of the avoidance hole one by one. The power supply connection component is arranged inside the fixing post. The power supply connection component has a fixed end fixed to the fixing post and a free end that contracts inside the fixing post under its own elastic force. The free end of the power supply connection component can move out of the fixing post through the through hole and at the same time move out of the housing through the avoidance hole under the push of an external force.

[0036] Embodiment

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 which is the overall structural schematic diagram of the present utility model, Figure 2 and

[0038] Please refer to Figure 3 , Figure 3The utility model is an exploded schematic diagram. The rail head 2 includes a housing 21 and a lamp connecting component 22 disposed in the housing 21. The lamp connecting component 22 includes a disc-shaped mounting seat and a cylindrical body. The outer surface of the body is provided with threads. An arc-shaped avoidance groove 211 is provided at the bottom of the housing 21. The lamp connecting component 22 is clamped in the avoidance groove 211. More specifically, the disc-shaped mounting seat is clamped in the avoidance groove 211. Such a design facilitates the later replacement of the lamp connecting component 22. The lamp 3 is screwed to the cylindrical body. The lamp 3 includes a back plate 31. The back plate 31 is provided with a mounting hole. The inner wall of the mounting hole is provided with threads. The lamp 3 is screwed to the cylindrical body of the lamp connecting component 22 through the mounting hole. Such a design allows for flexible disassembly and installation of the lamp 3.

[0039] See also Figure 2 The track 1 is provided with a guide groove inside, and a plurality of conductive metal wires 11 are embedded in the guide groove. The conductive metal wires 11 are specifically copper wires in this embodiment. Figure 4 , Figure 4 The figure is a schematic diagram of the explosion of the rail head of the utility model. The rail head 2 is also provided with avoidance holes 212 on both sides of the outer shell 21. The outer shell 21 is also provided with a fixing column 23, a power supply connection component 24 and a driving power supply 25. Designing the driving power supply 25 in the outer shell 21 of the rail head 2 not only reduces the number of external connection cables, making the system more neat and beautiful, but also simplifies the installation process, and there is no need to consider the wiring problem. At the same time, the built-in driving power supply 25 can also reduce the risk of electric shock. The two ends of the fixing column 23 are fixedly connected to the outer shell 21. The fixing column 23 is provided with a through hole, and the position of the through hole corresponds to the position of the avoidance hole 212. The power supply connection component 24 is arranged inside the fixing column 23. It is a metal spring sheet, such as a copper sheet, which has a conductive function. The power supply connection component 24 has a fixed end fixed to the fixed column 23, and a free end that shrinks inside the fixed column 23 under its own elastic action. The free end of the power supply connection component 24 can be moved to the outside of the fixed column 23 through the through hole under the action of external force and at the same time moved to the outside of the shell 21 through the avoidance hole 212. After the free end of the power supply connection component 24 passes through the through hole and the avoidance hole 212, it is finally overlapped with the conductive metal wire. The overlapping method can be specifically welding, crimping or screw fixing, etc., and conductivity is achieved through overlapping. The lamp 3 and the power supply connection component 24 are both electrically connected to the driving power supply 25.

[0040] See also Figure 3 The lamp 3 further includes an aluminum substrate 32, a lens assembly 33 and an anti-glare assembly 34. The aluminum substrate 32 is disposed on the back plate 31. At least two LED light source groups 321 are disposed on the aluminum substrate 32; see Figure 5 , Figure 5This is an enlarged view of the LED light source group of the present utility model. Each LED light source group 321 includes at least two LED lamp beads, preferably fourteen. These fourteen LED lamp beads are arranged in a 3-4-4-3 formation, making the entire arrangement formation approach a circular shape. This circular-approaching arrangement formation is more conducive to the light being more evenly dispersed within the lens assembly to avoid the generation of light spots. The LED lamp beads are fixed on the aluminum substrate 12 and are all electrically connected to the driving power supply 25; the lens assembly 33 is arranged on the aluminum substrate 32. The lens assembly 33 includes a lens bracket 331 and a plurality of hemispherical lens bodies 332. The outer surface of the lens body 332 is smooth, and the inner surface is uniformly provided with reflective scales. The light emitted by multiple LED lamp beads undergoes a reflection and mixing effect through the reflective scales of the lens body, making the light source more uniform after emerging from the lens. The lens bracket 331 and the plurality of lens bodies 332 are integrally formed, which can save installation time. The lens bracket 331 is fixedly connected to the aluminum substrate 32 by screws. A pair of LED light source groups 321 are correspondingly clamped within one lens body 332. By clamping multiple LED lamp beads within each hemispherical lens body, not only can the luminous efficiency of the entire track light be improved, but also the light spots or shadows that may appear in a single LED lamp bead can be eliminated; the anti-glare component 34 is arranged on the back plate 31. The anti-glare component 34 includes an anti-glare cover and a plurality of anti-glare cups. The anti-glare cover and the plurality of anti-glare cups are integrally formed. This modular and integrally formed design is conducive to improving the assembly efficiency of the track light and is also very convenient for later maintenance. The anti-glare cover is fixedly connected to the back plate 31. The lens assembly 33 and the anti-glare cover can be made of any one of polymethyl methacrylate, polycarbonate, and silicone. These materials have the advantages of high light transmittance and easy processing and forming; one lens body 332 is correspondingly clamped within one anti-glare cup 342. The anti-glare cup 342 is a cover body surrounded by four inclined surfaces. The outer side of the cover body gradually expands into a horn shape. The connection between the inclined surfaces is designed with a smooth arc transition. The anti-glare cup 342 designed in this way can confine the light beam angle of the LED light source group within the range of 60~90°, thereby reducing the URG value of the track light; the inner peripheral surface of the anti-glare cup 342 is provided with a grid optical surface. Each grid surface of the grid optical surface is an outwardly convex curved surface, and the outwardly convex curved surface satisfies the equation , where z is the sagittal height of the curved surface and z>0, c is the curvature of the curved surface and c>0, k is the quadratic surface coefficient, r is the radial height, and m is a non-negative integer. The anti-glare cup 342 is also provided with a spark pattern light-transmitting film or a sawtooth pattern light-transmitting film on the outwardly convex curved surface. The outwardly convex curved surface can further adjust the divergence angle of the light. In combination with the use of the spark pattern light-transmitting film or the sawtooth pattern light-transmitting film, the light effect is made softer and the track light is prevented from generating glare.

[0041] In order to improve the heat dissipation performance of the track light and extend the service life of the track light, in this embodiment, a heat sink is further provided on the aluminum substrate 32. The heat sink can be heat dissipation fins or a heat conduction pad. The setting of heat dissipation fins or a heat conduction pad on the aluminum substrate 32 is prior art and will not be elaborated here; graphene heat dissipation films are provided on both the back plate 31 and the anti-glare cover on the side facing the aluminum substrate 32.

[0042] The above are only the embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model.
