Problems solved by technology

The main function of the currently used color wheel device is to filter and separate the light from the light source or to reflect the required color light when it is excited. It does not have its own heat dissipation device, so it completely relies on the heat dissipation device in the projector system to assist in heat dissipation. cooling performance without any help

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] see figure 1 As shown, it is a schematic diagram of the light path of the projector color wheel device of the present invention. The color wheel device 10 is arranged in the light path formed by a laser light source 20 and a lens group 30, and the color wheel device 10 is located in the laser light path. On one side of the light source 20 , the lens group 30 is located at the front end of the color wheel device 10 . The laser light source 20 mainly provides a laser beam and projects it to the lens group 30 , and the lens group 30 guides the laser light source 20 to irradiate the color wheel device 10 . The color wheel device 10 includes a motor 12 and a color wheel 14 . The lens group 30 at the front end of the color wheel 14 has a two-way dichroic mirror 32 and two lenses 34, 36, and the two lenses 34, 36 are respectively located on both sides of the two-wa...

Abstract

The invention provides a color wheel device of a projector. The color wheel device comprises one motor and one color disk, wherein a motor is coupled with the color disk and drives the color disk to rotate; the color disk is provided with one illumination zone and one non-illumination zone; the illumination zone is located on the outer circumference of the color disk and provided with at least one fluorescent layer; and the non-illumination zone is located on the inner edge of the color disk and provided with a plurality of fan blades. According to the color wheel device of the projector, by means of the fan blades on the color disk, cooled air flows can be produced during rotation, and the heat dissipation efficiency of the color wheel device is improved.

Description

technical field [0001] The invention relates to a projector color wheel device, in particular to a projector color wheel device provided with fan blades. Background technique [0002] The light sources used in general projectors, such as tungsten-halogen lamps, metal halide lamps, ultra-high pressure mercury lamps, xenon lamps, etc., have common characteristics such as overheating, high power consumption, low bulb life, large size, light weight and Not easy to carry. Especially the part that generates high temperature needs to be dissipated by cooling device to maintain the normal operation of the projector. In recent years, the development of electronic products has developed in the trend of "light, thin, short, small, and low cost", and optical projector products are no exception. They are used in the light source part for relatively low power consumption, less heat generation, and smaller size And long life light emitting diode (LED) or laser light is used as the light ...
