Description

Technical Field

[0001] The utility model relates to a lamp, in particular to a lamp with high reliability. Background Art

[0002] In order to improve the heat dissipation effect of the lamp, a radiator is installed on the light source assembly. The radiator has multiple heat dissipation fins for heat dissipation. When it is necessary to install a power box or other structures on the radiator, connectors are usually directly driven into the power box or other structures and connected to the heat dissipation fins. However, due to the thin thickness of the heat dissipation fins, the mechanical strength is insufficient and the stress points are easy to fall off. The lamp assembled in this way has poor load-bearing strength and vibration resistance and low reliability. Therefore, a lamp with a more stable and reliable connection structure is urgently needed. Utility Model Content

When assembled with each other, the connecting piece passes through the heat sink 200 in the up and down directions, and the top end of the connecting piece is connected to the power box 100, and the bottom end of the connecting piece is connected to the light source assembly 300. At this time, the connecting piece is used to tighten the power box 100 and the light source assembly 300 and position them on the upper and lower sides of the heat sink 200. In this way, there is no need to drive a connecting structure into the heat sink 200 to form a connection force point.

During operation, the heat generated by the light source assembly 300 is transferred upward to the heat sink 220 through the base plate 210. The heat sink 220 is used to increase the heat exchange area with the air, and the air can pass through the heat dissipation gaps, thereby improving the heat dissipation efficiency of the light source assembly 300.
