LD laser light source module

Abstract

The invention relates to the technical field of illumination parts, and discloses an LD laser light source module. The LD laser light source module includes an LD light source, a reflection componentand a powder piece which are successively arranged in the light radiating the direction of the LD light source; and lights radiated by the LD light source are blue rays, the powder piece and the LD light source are arranged in a parallel mode, the powder piece is coated with yellow phosphor powders which are combined with the blue rays to be white lights, the reflection component is used for reflecting the lights radiated by the LD light source to the powder piece, and then the lights are reflected off through the powder piece. Compared with the prior arts, the LD laser light source module hasthe beneficial effects that the luminous power is high, the brightness is high, the definition is high, the luminous distance is long, and the size is small.

Description

technical field [0001] The present invention relates to the technical field of lighting devices, and more specifically, to an LD laser light source module. 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. In the flashlight lighting market, lighting products that use LD laser light source modules as light sources are relatively rare. Only traditional LED or metal halide lamps are used as light-emitting media, which makes the types of light-emitting media in the lighting industry relatively single, which cannot...
