Description

Outdoor LED lights with good heat dissipation and waterproof performance

technical field

The invention relates to an outdoor LED lamp, in particular to an outdoor LED lamp with good heat dissipation and waterproof performance.

Background technique

The products of outdoor LED lights are diverse, including street lights, wall washers, projection lights, camping lights, etc. Among them, the projection lamp and the wall washer are generally installed outdoors for a long time, so the requirements for waterproofing are very high. The existing projection lamp and wall washer structure includes a lamp housing, which is provided with a lighting cavity for installing LED light source components and a power supply cavity for placing a power module. In order to improve waterproof performance, both the lighting cavity and the power supply cavity Fully sealed to prevent rainwater from penetrating into the lamp. However, the fully sealed structure hinders the circulation of the gas inside the lamp and the outside world. When the lamp is in working state, the heat is not easy to dissipate to the outside, and the accumulated heat affects the life of the LED light source components; at the same time, the gas in the lamp expands due to heat. If the power is too high, the glass cover will be blown due to excessive gas expansion. In order to prevent accidents, the power of existing outdoor projection lights and wall washers is limited to a small range and cannot be made larger. Power outdoor spotlights and wall washers.
