Abstract

The present invention is suitable for the technical field of image display devices, and provides a projection device. The projection device comprises a housing and a light source device, a color separation device, a light modulation device, an image combination device and an optical projection device which are arranged in the housing. The light source device comprises one or more than one quasi natural light LED light sources which emit quasi natural light, the relative spectrum power of the red light in the quasi natural light is larger than 0.60, the relative spectrum power of the cyan lightin the quasi natural light is larger than 0.30, the relative spectrum power of the blue light in the quasi natural light is smaller than 0.75, the blue light colour index is smaller than 5.7%, and the color rendering index of the quasi natural light is larger than 95. The projection device employs the natural light LED light sources to form a light source module arranged in the housing to providea comfortable and pleasant luminous environment being closer to the sunlight, improves the contrast and the saturability after the image combination, reduces the blue light relative spectrum power, improves the color rendering index and can effectively reduce the damaging of the blue light for human bodies' eyes.

Description

technical field [0001] The invention belongs to the technical field of image display devices, and in particular relates to a projection device. Background technique [0002] Projection equipment is an optical instrument that uses optical components to enlarge the outline of an image and project it onto a video screen. It is currently widely used in homes, offices, schools and entertainment venues. According to different working methods, there are CRT, LCD, DLP and other different types. The working principle of the projection equipment is to separate the mixed white light of the white light source into three primary colors (R, G, B) through optical elements, corresponding to the characteristics of each pixel on the image, and the light of the three colors passes through the light modulation device to form corresponding characteristics The image is magnified by the projection device and projected onto the screen. [0003] Although the current projection equipment has high b...
