Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamps, in particular to a spotlight radiator structure. Background Art
[0002] Spotlights are a typical modern style of lighting without a main light and a fixed scale. They can create an indoor lighting atmosphere. Spotlights can be placed around the ceiling or on the top of furniture, inside the wall, in the wall skirt or skirting. The light is directly shone on the household objects that need to be emphasized, so as to highlight the subjective aesthetic effect and achieve an artistic effect with prominent key points, unique environment, rich layers, strong atmosphere and colorful colors.
[0003] The working time of a spotlight is generally long, and a lot of heat will be generated inside it when working for a long time. The heat of existing spotlights is generally dissipated through heat dissipation ports, and some spotlights are radiated through heat dissipation fins installed on the outer shell, which cannot achieve a good heat dissipation effect. The heat generated by the spotlight when working for a long time is relatively large. As time goes by, the heat that cannot be dissipated in time accumulates in the outer shell, resulting in high internal heat, which seriously affects the service life of the spotlight. The spotlight is prone to malfunction during long-term work. The radiator of the existing spotlight is installed in the spotlight. When replacing the spotlight, the outer shell and the radiator need to be disassembled separately, and then the spotlight needs to be replaced. The operation is very complicated. For this reason, we propose a spotlight radiator structure. Utility Model Content

[0022] The radiator assembly 2 includes a connecting shell 4 and cooling fins 6. The connecting shell 4 is fixedly connected to the top of the spotlight body 1. A cooling hole 16 is opened in the center of the top of the connecting shell 4. Strip cooling holes 15 are opened at equal distances on the outside of the cooling hole 16 at the top of the connecting shell 4. Strip mounting holes are opened at equal distances on the outside of the connecting shell 4, and cooling fins 6 are fixedly connected in the strip mounting holes.
[0023] It should be noted that when the present invention is used, the L-shaped fixing plate 13 is first fixed to the spotlight installation position by bolts, and then the convex plate 9 on the outside of the spotlight body 1 is matched with the convex plate 9 on the connecting shell 4, and the two are fixedly connected by screws. When the spotlight is working, part of the heat generated is dissipated through the strip heat dissipation port 15 and the heat dissipation passage 16, and the other part is transmitted to the outside through the heat dissipation fins 6. At the same time, the fan 10 works to blow air to the heat dissipation fins 6 through the air outlet 12, so that the heat dissipation fins 6 are quickly cooled, thereby achieving a better heat dissipation effect. When the spotlight works for a long time, part of the heat cannot be discharged in time and accumulates inside the connecting shell 4. The temperature sensor 17 detects a signal and transmits the signal to the internal controller.

[0027] It should be noted that when the spotlight is working, the heat inside the connecting shell 4 can be conducted to the outside through the heat dissipation fins 6. At the same time, the fan 10 works to blow air to the heat dissipation fins 6 through the air outlet 12, so that the heat dissipation fins 6 are quickly cooled down, and then the heat inside the connecting shell 4 can be efficiently conducted out, thereby accelerating the heat dissipation inside the connecting shell 4.

The L-shaped fixing plate 13 has a certain height. After installation, there is a certain distance between the top of the connecting shell 4 and the installation surface, so that the heat inside the connecting shell 4 can be quickly dissipated through the strip heat dissipation port 15 and the heat dissipation vent 16.
