Problems solved by technology

Although this way of opening the slot can completely transmit the blue laser light without reducing the efficiency of the light source, however, this way of opening the slot to allow the blue laser to transmit is prone to wind shear due to the high-speed rotation of the color wheel. Noise, for example, its noise level may be as high as 80 to 90 decibels

Abstract

The present invention provides an optical color wheel component and an optical color wheel thereof. The optical color wheel comprises a base unit, a light-transmitting unit, and a fluorescent unit. The base unit comprises a central hole, a central axis, a light-transmitting region, and a reflective region. The central hole is arranged along the central axis. The light-transmitting region and the reflective region are connected to go around the central axis. The light-transmitting region is provided with a through hole. The light-transmitting unit is arranged in the through hole and is surrounded by the through hole. The fluorescent unit is arranged on the reflective region and goes around the central axis. The invention also provides an optical color wheel component.

Description

technical field [0001] The invention relates to an optical color wheel assembly and the optical color wheel thereof, in particular to an optical color wheel assembly and the optical color wheel used in a projection device. Background technique [0002] One of the characteristics of the projector is that it is not limited by the size of the screen because it does not require a fixed screen. As long as there is a flat surface available for projecting images, large-size images can be easily projected. Therefore, it has been widely used in various fields, such as using a projector to enlarge the picture to be projected in large-scale conference speeches, or being used in a home theater group. [0003] Currently common projectors use a color wheel (color filter or color wheel) driven by a high-speed motor inside the projector to separate and process colors. However, in the traditional color wheel structure, the part used for the transmission of the blue laser light source is mos...
