Description

Technical Field

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

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

[0003] The existing integrated track spotlight includes a power supply box slidably connected to the track, a direction adjustment support rod arranged on the power supply box, and a spotlight body hinged to the direction adjustment support rod. The spotlight body includes a spotlight housing and a light source assembly built into the spotlight housing. The light source assembly is electrically connected to the power supply box. The spotlight housing is provided with heat dissipation holes connected to the inner cavity. The light source assembly generates heat while emitting light, and the heat is mainly dissipated by air or heat conduction.

[0004] However, during the use of the track spotlight, there is a possibility that the heat dissipation holes of the spotlight housing are facing the power box, causing the heat emitted from the heat dissipation holes to directly impact the power box. In addition, the electrical components in the power box themselves will also generate heat, causing the power box to overheat and reduce its service life. Therefore, further improvement is needed.

[0018] By adopting the above technical solution, a heat sink is added to the cup holder to increase the heat dissipation area of ​​the cup holder. The heat accumulated in the lamp cup can be conducted to the outside of the lamp cup through the heat sink on the cup holder and dissipated into the surrounding air, thereby reducing the possibility of overheating of the lamp cup.

[0019] Preferably, the heat sink is fixedly connected to the inner peripheral wall of the cup holder.

[0020] By adopting the above technical solution, the 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.

[0021] Preferably, the heat sink is an arc-shaped fin.
