Problems solved by technology

However, due to the limitation of the optical characteristics of traditional LEDs and the way they scatter light in all directions, such existing projectors using traditional LEDs as light source devices not only have a high degree of color saturation and vividness of their images The

Embodiment Construction

[0013] The above and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0014] Please refer to FIG. 1 , which is a schematic diagram of the light path of the first preferred embodiment of the projector using the laser LED as the light source device of the present invention. Wherein, the projector mainly includes: at least one laser LED (Laser Light Emitting Diode) light source 10, at least one beam expanding component 20, a light combining device (Cross Type Color Filter) 30, a light guide component 40, a prism group 50 , a digital micro mirror display device DMD (Digital Micromirror Device) 60 and a projection lens group 70 are combined.

[0015] In this embodiment, the laser LED light source 10 includes three sets of laser LEDs (10a, 10b, 10c) that can generate three primary colors of red, green, and blue (R, G, B) with different spectra. Due to the unique light-emitting char...

Abstract

This invention is a sort of single-disc panel projection which uses the laser LED to be the power, it consists of a laser LED power at least, a extender groupware at least, a composing light set, a leading light groupware, a prism group, a figure micro-lens display unit, and a projection lens group. It uses the small diameter laser bean of primary colors with the red, the green, and the blue which is produced by the laser LED, after the laser bean is to be magnified, combined the light, and transmitted the light by the extender groupware, the combining light set, and the leading set. It makes the bean of light to cast to the display unit of the numeral micro-lens by the prism group, after the image of the display unit of the numeral micro-lens is refracted to the projection lens and fabricated, it is cast to the outside. This invention attains this excellence in that: its image quality is sharper, its image is more vivid, its color is more saturated, its bulk is small, its power consumption is few, its feedback is fast, its life-span is long, and its efficiency is high, and so on by the laser LED.

Description

technical field [0001] The invention relates to a projector and a light source device thereof, in particular to a laser LED as a light source, and a beam expander assembly is used to expand the beam to a certain extent when the laser beam passes through the beam expander assembly. It can also be used in a single-chip panel projector as its light source device. Background technique [0002] With the rapid development of the technological era, all kinds of information and electronic products and equipment have been created, and all kinds of product components are moving towards the goal of being light, thin and short. How to make products more user-friendly and more portable Due to engineering, it is one of the main issues in the current market to meet the needs of consumers' convenience. [0003] The vigorous development of optoelectronics industry in my country over the past ten years has established a solid experience and technology in optical design, simulation, process, ...
