LED light source device

Abstract

The invention provides an LED light source device. The LED light source device comprises a substrate body formed as a piece shape; multiple through grooves are spaced in the connecting line direction of the outer peripheral edge of the substrate body and the center of the substrate body for dividing the substrate body into multiple connected substrate units; the lengths of the through grooves are smaller than the distance from the outer peripheral edge of the substrate body to the center of the substrate body; the substrate units have first surfaces; multiple LED light source sites are arranged on first surfaces of the multiple substrate units for placing LED light sources; the LED light sources are LED patch light sources; and each substrate unit can be randomly bent, so that an illumination surface irradiated by all the LED light sources is not lower than a maximum preset illumination surface. The LED light source device solves the illumination dead angle and cooling problems through the through groove and division technologies, and improves the circuit stability.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to an LED light source device. Background technique [0002] The new national standard for elevators requires the lighting of shafts, pits, and car tops to reach 20LUX in most areas of the shaft. Since the elevator shaft is a vertical structure, the illuminance in the shaft should reach all directions as far as possible, especially the illumination in the vertical direction, so as to achieve the lowest number of lights to cover the entire shaft. [0003] However, the existing LED lights generally adopt LED flat panel light sources. Since the maximum emission angle of the LED patch is generally 150°, the side light, especially the side light greater than 150°, cannot reach the front of the vertical plane. Therefore, the LED flat panel light source has problems such as lighting blind spots. In order to solve the problem of lighting dead angles, a method of increasing the n...

Problems solved by technology

[0004] The inventors of the present application found that the above-mentioned solutions to the lighting dead angle and heat dissipation problems cannot completely improve the lighting and heat dissipation performance of the LED lamp, and the root cause is that the substrate for the printed circuit board (PCB) has not been solved.

[0005] An object of the present invention is to provide an LED light source device to solve the problems of lighting dead angle and heat dissipation
