Worklights are lamps used for various outdoor applications such as construction lighting. They are usually installed around the construction site or on large equipment such as strangers and cranes for lighting at night or when the line of sight is poor. The work of the prior art The lights are all light source (LED, Light-emitted Diode) as the light source. Because of the high brightness of white light, it can clearly illuminate the surrounding of the work site, but also because of the high brightness and the intensity reflected from the obstacles. Strong, when the fog at the work site is diffused, the white light is reflected back from most of the light sources that are emitted, and it is not easy to penetrate the fog layer, creating a smoggy scene; in other words, white light is in a field with low visibility such as fog and windy sand. In the domain, its penetration is not ideal, and it can not effectively improve the visibility of work.
