Light source apparatus

Abstract

The invention provides laser projection equipment and a light source apparatus thereof. The light source apparatus comprises a light source, a fluorescent wheel and a reflective bowl; an excited light beam is projected to the fluorescent wheel to generate three primary lights with timing sequence; the three primary lights come to the interior of the reflective bowl; the inner side surface of the reflective bowl comprises a green light reflective region, a red light reflective region and a blue light reflective region; and the reflective bowl rotates according to the emergent timing sequence of the three primary lights to enable the three primary lights to come to the green light reflective region, the red light reflective region and the blue light reflective region respectively. In the light source apparatus, by virtue of the rotary reflective bowl, the three primary lights generated by the fluorescent wheel can be converged and color filtered, so that the microminiaturization development of the laser projection equipment can be facilitated.

Description

technical field [0001] The invention relates to the field of laser projection, in particular to a light source device. Background technique [0002] In the light source device technology of laser projection equipment, the laser is usually irradiated on the phosphor wheel coated with phosphor powder to form three primary colors. For example, if figure 1 A light source device is shown, which includes a laser 1 and a fluorescent wheel 2 . Laser 1 can be a blue laser. The fluorescent wheel 2 is coated with green fluorescent powder and yellow fluorescent powder. A fluorescent area and a laser transmission area are arranged on the fluorescent wheel 2, and as the fluorescent wheel rotates, the laser beam is periodically irradiated on the fluorescent area and the laser transmission area. [0003] The blue laser light is incident on the surface of the fluorescent wheel, and with the rotation of the fluorescent wheel, different fluorescent areas are irradiated by the laser light, ...

AI Technical Summary

Problems solved by technology

In the above-mentioned light source device, the number of optical path components is large and the optical path is long, resulting in a large volume of the entire light source device, which is not conducive to the miniaturization of the light source device.
