Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a track light with a quick-change reflector. Background Technology

[0002] Track lights are adjustable lighting fixtures installed on a track, widely used in commercial shops, showrooms, living rooms, and other places. Their core feature is the ability to flexibly move and adjust the angle of the lights through a track system, meeting diverse lighting needs.

[0003] Traditional track lights typically use a fixed structure for their internal optical components, making it impossible to quickly replace them and unsuitable for various usage scenarios. In another type of track light, the front ring uses a threaded knob for installation, making it very inconvenient to replace the light source components.

[0004] Therefore, improvements are needed. Utility Model Content

[0005] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a track light with a quickly replaceable reflector cup, thereby resolving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a track light with a quickly replaceable reflector, comprising: a track head, wherein a hanging rod is provided on the track head; a heat sink, wherein an installation space is provided inside the heat sink, the upper end of the heat sink is connected to the hanging rod, and the lower end of the heat sink is provided with a connecting structure; a light source assembly, wherein the light source assembly is installed inside the heat sink and provides illumination; a reflector, wherein the reflector is disposed inside the heat sink, the upper end of the reflector abuts against the light source assembly, and the lower end of the reflector is provided with glass; and a front ring, wherein the front ring is assembled to the connecting structure and the front ring confines the glass and the reflector within the heat sink.

[0007] Furthermore, the connecting structure is a slot recessed along the inner wall of the radiator; the front ring is engaged in the slot to fix the glass and the reflector cup.

[0008] Furthermore, the outer periphery of the front ring is provided with a flange that matches the slot.

[0009] Furthermore, the front ring is made of silicone material.

[0010] Furthermore, the light source assembly includes a COB light source and a light source bracket, wherein the light source bracket secures the COB light source within the heat sink using fasteners.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Optimized installation structure: A slot-type connection structure replaces the traditional threaded knob solution, simplifying the installation and removal process of the reflector cup from "multiple turns of knob adjustment" to "single-step snap-fit ​​fixing". The silicone front ring provides sufficient elastic deformation to achieve reliable snap-fit.

[0013] Replaceable design: With the front ring reflector design, users can quickly replace the reflector with different reflective angles (such as 15° / 24° / 36°) to meet the needs of different usage scenarios. Attached Figure Description

[0022] In view of the technical problems described in the background art, as shown in the figure, a track light with a quickly replaceable reflector cup 5 is provided, comprising: a track head 1, on which a hanging rod 2 is provided; a heat sink 3, which has an installation space inside, the upper end of which is connected to the hanging rod 2, and the lower end of which is provided with a connecting structure; a light source assembly 4, which is installed inside the heat sink 3 and provides illumination; a reflector cup 5, which is disposed inside the heat sink 3, the upper end of which abuts against the light source assembly 4, and the lower end of which is provided with glass 6; and a front ring 7, which is assembled to the connecting structure and limits the glass 6 and the reflector cup 5 within the heat sink 3.

[0023] This utility model provides a track light with a quick-change reflector cup 5, which mainly includes a track head 1, a heat sink 3, a light source assembly 4, a reflector cup 5, a glass 6, and a front ring 7.

[0024] The track head 1 is used to move and adjust its position in conjunction with the track, and the hanger 2 is hinged to the radiator 3, so that the radiator 3 can rotate and adjust its position relative to the hanger 2.

[0025] The heat sink 3 is typically made of die-cast aluminum alloy or extruded profile, with internal mounting space for optical and electrical components. The upper end of the heat sink 3 is fixedly connected to the suspension rod 2 below the track head 1 via screws or clips, preferably using screws. The track head 1 is used to mount the entire luminaire on an external power rail. The lower opening of the heat sink 3 has a connecting structure on its inner wall, which is used in conjunction with the front ring 7.

[0026] The light source assembly 4 is installed in the upper part of the mounting space inside the heat sink 3.

[0027] A reflector 5 is housed inside the heat sink 3. The reflector 5 has a funnel-shaped structure and is located below the light source assembly 4. The upper opening edge of the reflector 5 abuts against the lower surface of the COB light source or the light source bracket to ensure efficient light reflection. A piece of glass 6 is placed at the lower opening of the reflector 5. This glass 6 can be transparent glass 6, frosted glass 6, or anti-glare glass 6, etc.

[0028] The front ring 7 is ring-shaped, and its circumferential edge is assembled with the connecting structure to fix the glass 6 and the reflector cup 5 inside the radiator 3.

[0029] As shown in the figure, the connecting structure is a groove 8 recessed along the inner wall of the heat sink 3; the front ring 7 is engaged in the groove 8 to fix the glass 6 and the reflector 5. The outer periphery of the front ring 7 is provided with a flange 9 that matches the groove 8.

[0030] In a preferred embodiment, the inner wall of the lower opening of the radiator 3 is radially recessed. In this embodiment, the connection structure is specifically manifested as an annular groove 8. The front ring 7 has a radially outwardly protruding annular flange 9 on its outer circumference. The inner diameter of the front ring 7 is slightly smaller than the outer diameter of the glass 65.

[0031] Preferably, the front ring 7 is made of silicone. It has a certain degree of elasticity, making it easy to install and disassemble.

[0032] Preferably, the light source assembly 4 includes a COB light source and a light source bracket, wherein the light source bracket fixes the COB light source inside the heat sink 3 by fasteners.

[0033] The light source assembly 4 specifically includes a COB light source and a light source bracket. The light source bracket is typically made of metal or high-temperature resistant plastic. The light source bracket, together with the COB light source 31, is fixed to the bottom plane of the heat sink 3 using fasteners (such as screws) to facilitate heat dissipation.

[0034] The specific usage process is as follows: During assembly, first place the reflector cup 5 into the heat sink 3, then place the glass 6 at the bottom of the reflector cup 5. Finally, align the silicone front ring 7 with the slot 8 at the lower port of the heat sink 3 and insert it. Due to the elasticity of the silicone, the operator can easily push the front ring 7 inward into the port of the heat sink 3 with a little force. After being compressed and deformed, the flange 9 on the outer periphery of the front ring 7 slides into the slot 8 on the inner wall of the heat sink 3. When the flange 9 is fully inserted into the slot 8, it will be locked in the slot 8 by the elasticity of the silicone, achieving axial locking. At this time, the inner edge of the front ring 7 contacts the surface of the glass 6, forming a stable optical component module.

[0035] Replacement procedure: When the user needs to replace a different reflector cup 5, simply pull the flange 9 of the front ring 7 out of the slot 8 to remove the front ring 7. Then, remove the glass 6 and the old reflector cup 5 in sequence. Insert the new reflector cup 5 and glass 6, and then reattach the front ring 7 to complete the replacement. The entire process can be completed in tens of seconds, making it extremely convenient.

[0036] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
