Abstract
The invention belongs to the technical field of illumination equipment, and particularly relates to an LED light emitting device and a site project lamp. The LED light emitting device comprises a light source module and a lens module; the light source module comprises a PCB and a plurality of LED light emitting units, and all the LED light emitting units are laid out on the PCB in an arrayed mode;the lens module comprises a transparent cover plate and a plurality of lenses, and all the lenses are laid out on the PCB in the arrayed mode; the bottoms of all the lenses are all sunken to form cavities, and all the cavities directly face all the LED light emitting units correspondingly; and compound eye structures are formed on the bottom faces of all the cavities correspondingly. The bottomsof all the lenses are sunken to form the cavities, the compound eye structures are formed at the bottoms of the cavities, thus single light beams emitted by the LED light emitting units can be dividedinto a plurality of fine light beams which are mutually crossed and superimposed, all the fine light beams compensate micro unevenness of the fine light beams, thus the LED light emitting device is good in light color processing, and a light spot center and peripheral yellow spots which are irradiated by the light beams of the LED light emitting device are eliminated.
Description
technical field [0001] The invention belongs to the technical field of lighting equipment, and in particular relates to an LED lighting device and a site floodlight. Background technique [0002] As more energy-saving and environmentally friendly lamps, LED lamps also have relatively good lighting effects. They have gradually replaced traditional light source lamps and have been promoted and used in places with high lighting requirements such as gymnasiums. [0003] In the prior art, although LED lamps can meet the lighting requirements of gymnasiums and other places, there are still yellow spots on the edges of the light spots emitted by them, which will affect the lighting effect, resulting in uneven darkness and mottled colors in the lighting place. Contents of the invention [0004] The object of the present invention is to provide an LED light emitting device and a venue floodlight, aiming to solve the technical problems of the yellow spots in the light spots emitted ...
