Embodiment Construction

[0016] 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.

[0017] 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.

[0018] Unless otherwise defined, all technical and scientific terms used here...

Abstract

The invention provides a solid-state light source device which comprises at least one light source group, a conversion device, at least one light combining device and a light guide assembly. The lightsource group is used for projecting the monochromatic light with high intensity to the conversion device, the conversion device converts the monochromatic light into the white mixed light, and the light combining device is an oval reflecting mirror. The conversion device is arranged on a first focus of the light combining device, the light guide assembly is arranged on a second focus of the lightcombining device, and the white mixed light converted by the conversion device is transmitted from the first focus of the light combining device, is mixed and condensed by the light combining deviceand then is projected into the light guide assembly at the second focus. The solid-state light source device is simple in structure, and the lumen brightness of a projector can 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...
