<p>An LED light source, including a heat dissipation base. The surface of the heat dissipation base is fixed thereon with a circuit base, the circuit base is fixed thereon with an LED, a lens is connected outside the heat dissipation base in a sealed way, a housing is fixed outside the lens, the front end of the housing and the front end of the lens are respectively connected to a light transparent cover, the light transparent cover is connected to the heat dissipation base in a sealed way, the circuit base and the LED are both located inside a first sealed cavity formed by the lens, the heat dissipation base and the light transparent cover. The heat dissipation base is further provided thereon with at least one channel, wherein each channel does not communicate with the first cavity and two opposite openings of each channel communicate with the exterior. It has good heat dissipation effects and is particularly applicable to large power LED illumination.</p> |
