Abstract
A LED light source, comprising a heat-dissipation base, a circuit base is fixed on the heat-dissipation base, and luminous LED(s) is fixed on the circuit base, a light-distribution lens is sealed connected outside the heat-dissipation base, a housing is fixed outside the light-distribution lens, and front ends of the housing and the light-distribution lens are separately fixed jointed to a light-transmitting cover, the light-transmitting cover is sealed connection with the heat-dissipation base, the circuit base and LEDs are located within a sealed first chamber formed by the heat-dissipation base, light-distribution lens and light-transmitting cover, at least a channel is further arranged on the heat-dissipation base, each channel is disconnected to the first chamber, and two opposite openings of each channel are connected to the exterior. The LED light source has a good heat-dissipation performance, particularly to be used for high-power LED illumination.
