Description

technical field [0001] The invention relates to a work lamp, in particular to a work lamp which adopts LED as a light source and is applied to an engineering vehicle, and belongs to the technical field of lighting. Background technique [0002] At present, the light sources of conventional engineering vehicle work lights are incandescent lamps, halogen lamps or xenon lamps. Work lights with this type of structure are simple in structure and cheap in price; High energy consumption is not conducive to energy conservation and environmental protection; moreover, on November 1, 2011, the National Development and Reform Commission, the Ministry of Commerce, the General Administration of Customs, the State Administration for Announcement on Incandescent Lamps, it was decided that from October 1, 2012, the import and sale of incandescent lamps for general lighting will be gradually banned in stages according to their power; Improvements have been made to the overall work lights. ...
