Description

Technical Field

[0001] The present application relates to the technical field of lamps, and in particular to a lamp cup structure of a track spotlight. Background Art

[0002] Track spotlights are widely used for lighting in shopping malls, hotels, windows and other places. They are mostly aluminum alloy shells with built-in LED light sources. They are colorful, environmentally friendly and energy-saving, light and simple, and beautiful. When used, they are installed on tracks or directly on the ceiling or wall, which can solve the basic lighting and highlight the lighting requirements of key projection.

[0003] The existing track spotlight mainly includes a power box, a direction adjustment support rod arranged on the power box, and a spotlight body arranged on the direction adjustment support rod. The spotlight body includes a spotlight housing, a lamp cup built into the spotlight housing, a light source chip built into the spotlight housing and arranged at one end of the lamp cup, and a lens fixedly connected to the other end of the lamp cup. In the prior art, a heat dissipation hole connected to the inner cavity is provided on the spotlight housing. The light source chip generates heat while emitting light, and the heat is mainly dissipated by air or heat conduction. However, some heat will still accumulate in the lamp cup, which may easily cause the lamp cup to overheat. The inner wall of the lamp cup is coated with a reflective film, and its shape and structure will change, which may easily lead to a decrease in light uniformity. Therefore, further improvement is needed. Utility Model Content

[0004] In order to reduce the possibility of overheating of the lamp cup, the present application provides a lamp cup structure of a track spotlight.

[0008] Preferably, the first heat sink is fixedly connected to the inner peripheral wall of the cup holder.

[0009] By adopting the above technical solution, the first heat sink is fixed to the inner peripheral wall of the cup holder, which, on the one hand, improves the flatness of the appearance of the cup holder, and on the other hand, can achieve the purpose of anti-glare.

[0010] Preferably, the first heat sink is an arc-shaped fin.

[0011] By adopting the above technical solution, the first heat sink is an arc-shaped fin, which increases the area of ​​the first heat sink and improves the heat dissipation effect of the first heat sink.

[0012] Preferably, a limiting ring is coaxially fixed on the outer peripheral wall of the light-emitting end of the lamp cup body, and the cup holder includes a front ring sleeve that is clamped on the limiting ring and an extension ring sleeve that is fixedly connected to one end of the front ring sleeve away from the lamp cup body, the clamping groove is a recessed groove opened on the end surface of the front ring sleeve close to the lamp cup body, one end of the lens abuts against the inner wall of the extension ring sleeve close to the clamping groove, and the other end of the lens abuts against the end surface of the limiting ring, and the first heat sink is fixedly connected to the extension ring sleeve.

[0015] By adopting the above technical solution, when installing the cup holder, first slide the lens into the slot of the front ring sleeve, and then put the cup holder sleeve on the limiting ring. The limiting ring first abuts against the guiding inclined surface on the limiting clamping protrusion, thereby forcing the end of the buckle to elastically deform outward, thereby providing an escape space for the limiting ring. After the limiting ring is slid and inserted into the slot, the buckle is elastically reset, and the limiting clamping protrusion abuts against the end face of the limiting ring away from the lens, effectively preventing the limiting ring from sliding back and out of the slot, thereby achieving the fixation of the cup holder and the lamp cup body.

The lamp cup body 1 is arranged in a trumpet shape. The small end of the lamp cup body 1 is fixedly connected with a light source chip 3. The large end of the lamp cup body 1 is a light emitting end. The cup holder 2 is arranged at the light emitting end of the lamp cup body 1. In this embodiment, the lamp cup body 1 and the cup holder 2 are both made of aluminum alloy.

[0034] Reference Figure 2 , Figure 3 The outer peripheral wall of the light-emitting end of the lamp cup body 1 is integrally fixed with a limiting ring 11, and the limiting ring 11 is coaxial with the lamp cup body 1. The cup holder 2 includes a front ring sleeve 21 clamped on the limiting ring 11 and an extension ring sleeve 22 fixedly connected to the end of the front ring sleeve 21 away from the lamp cup body 1. The end surface of the front ring sleeve 21 close to the lamp cup body 1 is provided with a sink groove to form a clamping groove 23. The front ring sleeve 21 is provided with a lens 5 clamped in the clamping groove 23. One end of the lens 5 abuts against the inner wall of the clamping groove 23 close to the extension ring sleeve 22. The inner peripheral wall of the extension ring sleeve 22 is fixedly connected with a first heat sink 4. The first heat sink 4 is provided with a plurality of first heat sinks 4 and is spaced apart around the axis of the cup holder 2. In this embodiment, the first heat sink 4 is a straight sheet. In other embodiments, the first heat sink 4 can be an arc sheet.
