Abstract

The light source unit and the projector device ensure a certain amount of light by improving the light utilization efficiency, thereby achieving miniaturization. The light source unit includes: a reflection mirror having an opening for accommodating a lamp and an opening for radiating light, the reflection mirror having an inner surface which is mirror-finished to form a polynomial curved surface shape; The electrodes of the bulb are introduced into the light source of the unit, wherein the bulb is inserted into the reflector from the opening for receiving the lamp, and the bulb is arranged so that light emitted from the bulb is the focusing position of the light reflected by the inner wall is not located on the electrode introducing unit; and a converging lens for converging the light emitted from the reflecting mirror, wherein the converging lens is arranged to be located on the light source from the light source on the optical axis of the emitted light.

Description

technical field [0001] The present invention generally relates to a light source unit and a projector device equipped with the same, and more particularly, to a light source unit that is downsized without reducing the utilization efficiency of light emitted from the light source, and a projector device equipped with the light source unit. Background technique [0002] The projector device is configured to display an image on a screen by making the light emitted from the light source unit incident into a mirror tunnel after passing through a color wheel so that the light has a uniform intensity distribution, and by A micro mirror device, a liquid crystal display device, etc. switch the amount of light at each pixel to project the light. [0003] As shown in Figure 9, the light source unit 50 includes a light source 51 for radiating light, a convex lens 52 and a mirror tunnel 53, wherein the convex lens 52 is placed on the optical axis K for converging the light emitted from t...
