Embodiment Construction

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0013] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present.

[0014] Unless otherwise defined, all technical and scientific terms used here...

Abstract

The invention provides a solid-state light source device which comprises a light source group, a light combining device and a light guide assembly. The light source group comprises a laser light source, a scattering mirror and a fluorescent scattering mirror, a laser beam generated by the laser light source is divided into two beams, one laser beam irradiates the scattering mirror to generate thefirst color light, and the other laser beam irradiates the fluorescent scattering mirror to generate the second color light. The scattering mirror and the fluorescent scattering mirror are located inthe light combining device, the light combining device is a semi-elliptical hollow reflecting mirror, and the light combining device mixes and condenses the first color light and the second color light and then projects the first color light and the second color light into the light guide assembly. The solid-state light source device is simple in structure, and the lumen brightness of a projectorcan be effectively improved.

Description

technical field [0001] The invention relates to a light source device for a projector, in particular to a solid-state light source device with a simplified structure. Background technique [0002] Laser projector is a new type of projection equipment, because the projected image has a larger color gamut, higher brightness, contrast and color saturation, it has been widely concerned by people. [0003] The light beam of the first color emitted by the light source of the existing laser projector light source device, the light beam of the first color is projected to a fluorescent color wheel after being reflected by a two-way dichroic mirror, and then a light beam of the second color will be generated and A light beam of a third color, a light beam of a second color and a light beam of a third color are reflected by the fluorescent color wheel and then pass through the dichroic mirror; and part of the light beam of the first color passes through the fluorescent color wheel The...
