Abstract

The utility model discloses a ceiling-absorbing spotlight with good heat dissipation, which can be divided into two parts, namely a lamp body assembly and a ceiling-absorbing plate assembly. The utility model can reduce the use of other auxiliary installation tools through the shrapnel design and the internal and external thread design, thereby facilitating installation and disassembly, and is also beneficial to daily inspection and maintenance. In addition, the bracket plate is driven to connect the lighting main body with the circular lamp tube and the ceiling plate assembly. Compared with the lamps on the market that are only installed sequentially inside, the utility model has a certain strength and is not affected by impacts such as collisions. Parts are not easy to fall off or collide with each other. It is worth mentioning the technical heat dissipation. The heat sink is finned, and its heat sink can be made thinner, so that the heat dissipation area can be expanded to the greatest extent. The inner cavity of the heat sink is installed with a COB light source, and the top is close to the driver. The power supply can effectively dissipate the heat generated by these two working electrical devices. In addition, there are multiple holes on the ceiling plate. In addition to being used for installation and leading out wires, they can also be used as heat dissipation holes and cooperate with radiators. Its cooling effect is better.
