Embodiment Construction

[0051] The advantages and spirit of the present invention can be further understood through the following detailed description of the invention together with the accompanying drawings.

[0052] Referring to Fig. 3, the projector of the present invention includes a light source device 32, a non-visible light filter (UV / IR filter) 34, a color wheel (color wheel) 36, an integration rod (integration rod) 38 and other structures components.

[0053] The light source device 32 is used to provide light, and includes a bulb 3202 and a reflective lampshade 3204 . The light bulb 3202 is used to provide light, and the reflector cover 3204 is used to guide the light provided by the light bulb 3202 to a predetermined direction to form a predetermined light path.

[0054] The non-visible light filter 34 is disposed on the light path emitted by the light source device 32 to allow the visible light to pass and reflect the non-visible light.

[0055] The color wheel 36 is arranged on the opt...

Abstract

The invention relates to a projector that includes a light source device a color wheel, a color wheel reflecting guiding device. The invention designs part of the projector to tilted position state to guide a great deal of light emitting out of the light source device to solve the high temperature problem of the light source device.

Description

[technical field] [0001] The present invention relates to a projector, in particular to an integrated design of optics, heat transfer and mechanism used in the projector to reduce the temperature of the light source device. [Background technique] [0002] Referring to FIG. 1 , a conventional projector 2 includes a light source device 4 , an invisible light filter 6 , a color wheel 8 , an integrating column 10 , a light valve 12 , a projection lens 14 . . . and other components. [0003] Further please refer to FIG. 2 . FIG. 2 is a schematic diagram of an optical path of a conventional light source device 4 . The light source device 4 includes a light bulb 402 and a reflective lampshade 404 . Light is provided by the light bulb 402 of the light source device 4 , and the light provided by the light bulb 402 is guided forward by the reflector 404 to pass through a non-visible light filter (UV / IR filter) 6 . Wherein, the non-visible light filter 6 can allow the visible light t...
