Abstract

Lighting lamps includes lamp body. There are first space and secondary space in the lamp body. The radiating module is in the same first space, the secondary space is fully sealed space. So, dustproof, waterproof and antirust purpose are attained, and several luminous bodies are connected in the secondary space, as light source for illuminating. The luminous bodies are joined with radiating module of the first space, so radiating module can discharge the heat source generated from luminous bodies out of lamp body to reach the aim of heat exchange and radiating. So the service life of luminous body is prolonged.
