Blue light blocking LD laser light source module

Abstract

The invention relates to the technical field of illumination devices, and discloses a blue light blocking LD laser light source module which comprises an LD light source. Light emitted by the LD lightsource is blue light, and a laser connecting plate is arranged on a light emitting channel of the LD light source. The laser connecting plate is provided with light emitting through holes, wherein the size of the light emitting through holes is smaller than the diameter of light emitting beams of the LD light source on the laser connecting plate, and the light emitting through holes are used forlimiting the range of the beam diameter of the LD light source emitting light on the laser connecting plate. Compared with the prior art, the blue light blocking LD laser light source module limits the diameter range of the light emitting beams of the LD light source by forming the light emitting through holes in the laser connecting plate, and unnecessary or scattered blue light is prevented frompassing through the light emitting through holes, so that the blue light blocking LD laser light source module has the beneficial effects of more concentrated light emitting beams and better light emitting effect.

Description

technical field [0001] The present invention relates to the technical field of lighting devices, more specifically, to an LD laser light source module for blocking blue light. Background technique [0002] The English full name of LD is Laser diode, and the Chinese name is laser semiconductor, also known as laser diode. A laser is a device that amplifies light by inducing emission. Existing laser semiconductors are generally used in optical fiber communications, optical discs, laser printers, laser scanners, laser pointers (laser pointers) and other fields, while in the field of lighting, light source modules generally use LEDs as light-emitting media. Semiconductor light-emitting diodes; and lighting products that use LD laser light source modules as light sources are relatively rare. [0003] On the other hand, when the LD semiconductor laser diode is working, the light emitted is blue light, and at the same time, as Figure 4 As shown, the light size range value X emitt...
