Intelligent illuminating COB (Chip On Board) LED (Light Emitting Diode) light source device

Abstract

The invention discloses an intelligent illuminating COB (Chip On Board) LED (Light Emitting Diode) light source device, which comprises red, blue and green light emitting areas, wherein the red, blue and green light emitting areas are discretely distributed at interval, i.e., a green light emitting area is distributed at interval between red and blue light emitting areas; the green light emitting area is distributed around the red and blue light emitting areas to form integrally interconnected areas; an area above the red, blue and green light emitting areas consists of plane lenses and curved lenses on the plane lenses, and the curved lenses are located above a blue light emitting area. The interconnected areas form closely adjacent RGB all-color areas, any adjacent red and blue light emitting areas are a public reused area and the fewest RGB areas are used to form the most all-color areas. Since the blue light emitting area uses the curved lenses with a reflector respectively, the mistaken excitation of green fluorescent powder in the green light emitting area caused by a blue light chip installed therein is substantially avoided, the improvement of the color purity of the blue light emitting area is realized and the color range of the RGB COB device is increased.

Description

technical field [0001] The invention relates to the technical field of LED light source devices, in particular to an LED light source device for an intelligent lighting COB. Background technique [0002] RGB devices can realize free transformation of any color, and can be intelligently controlled according to the scene. They are very important smart lighting devices. At present, the realization of smart lighting devices is mostly composed of discrete RGB devices through patch combination, and the discrete devices are point light-emitting devices. , a specific color needs to be formed by the mixing of adjacent RGB devices. If the RGB devices are scattered, it is easy to cause color separation. The COB LED device is a surface-emitting LED device that can improve the uniformity of the lighting effect and is widely used in the field of white light lighting, but the products of intelligent lighting COB devices are very scarce. On the one hand, smart lighting COB devices need to ...
