Description

A split LED light source

technical field

The utility model relates to a split type LED light source.

Background technique

With the development of science and technology, LED solid-state lighting sources are widely used, and more and more of them are used as lighting sources. Existing LED light sources generally make the driver and the LED substrate into a structure that is not disassembled. Therefore, when the light source or a part of the driver is damaged, it is impossible to repair or replace some parts, and the entire light source can only be scrapped, which has caused a certain degree of damage. Waste, especially for high-power light sources, the cost is high, and the overall scrapping causes the use cost to be too high; in addition, the drive circuit of the existing LED light source is close to the heat sink, and the heat generated by the LED will affect the components of the drive circuit. For example, if the temperature is too high, the life of the capacitor will be shortened, resulting in a reduction in the life of the entire light source; in addition, for the existing lawn lights with the structure of R7s or RX7s lamp caps, due to the limitation of the housing space of the lamps, holding the light source in hand It is inconvenient to install and replace.
