Problems solved by technology

However, since the light source is generally a halogen bulb or an LED lamp, the collimation of emitted light is not good, and the projection direction of part of the light cannot be accurately controlled and cannot be projected onto the micromirror device without being utilized. Low

Embodiment Construction

[0011] Such as Figure 1-2 As shown, a light source system 100 provided by an embodiment of the present invention includes a first prism 10 , a second prism 20 , a first laser source 30 , a second laser source 40 and a third laser source 50 . The first monochromatic beam emitted by the first laser source 30, the second monochromatic beam emitted by the second laser source 40, and the third monochromatic beam emitted by the third laser source 50 are mixed into a white beam .

[0012] The first prism 10 is in the shape of a triangular prism, and its cross-section is an isosceles triangle. The first prism 10 is made of glass material, and its refractive index is n 1 . The first prism 10 includes a first incident surface 11, a first outgoing surface 12 connected to the first incident surface 11, and a first incident surface 11 connected to the first outgoing surface 12 between the first bottom surface 13. The cross sections of the first incident surface 11 and the first outgo...

Abstract

The invention provides a light source system which comprises a first prism, a second prism, a first laser source, a second laser source and a third laser source. A first single-color light beam emitted by the first laser source is reflected by the first prism and then combined with a second single-color light beam which is emitted by the second laser source and refracted by the first prism to form a mixed light beam, and the mixed light beam emits from the first prism. A third single-color light beam emitted by the third laser source is reflected by the second prism and then combined with the mixed light beam emitted from the first prism and refracted by the second prism to form a white light beam, and the white light beam emits from the second prism. By using laser as a light source, utilization rate of the light projected from the light source system is guaranteed.

Description

technical field [0001] The invention relates to a light source system, in particular to a light source system using laser light as a light source. Background technique [0002] A traditional projector includes a light source, a color wheel, and a micromirror device. The light projected by the light source passes through the color wheel and then projects to the micromirror device, and the micromirror device is controlled by an image signal. The light modulates the signal light and reflects it. However, since the light source is generally a halogen bulb or an LED lamp, the collimation of emitted light is not good, and the projection direction of part of the light cannot be accurately controlled and cannot be projected onto the micromirror device without being utilized. Low. Contents of the invention [0003] In view of this, it is necessary to provide a light source system with high light utilization efficiency. [0004] A light source system includes a first prism, a sec...
