Problems solved by technology

[0004] However, when the light source module 100 is assembled in an optical projection device, for example, the reflector 140 of the light source module 100 may not be located at the expected best reflection position due to factors such as structural tolerances, assembly tolerances, or optical tolerances.
Therefore, the optical path of the light beam recycled through the multiple penetrations or reflections of the beam splitter 130, the reflector 140, and the lamps 110, 120 will deviate from the pre-designed optical path, making the collection efficiency of the light source module 100 poor.

Abstract

The invention provides an optical element adjustable device, which is used for an optical projection device. The optical element adjustable device comprises a reflecting part, an elastic part and an adjusting screw. The reflecting part is suitable for rotating correspondingly to the first axis line; furthermore, the reflecting part is arranged on a transmission path of a light beam emitted by thelight source of the optical projection device. The reflecting part is suitable for reflecting light beams. The elastic part is coupled with the reflecting part; furthermore, the elastic part applies afirst moment on the reflecting part. The adjusting screw is provided with a cone which is provided with a conical surface which is provided with a coupling reflecting part. The cone applies a secondmoment on the reflecting part; furthermore, the direction of the first moment is opposite to the direction of the second moment.

Description

technical field [0001] The invention relates to an adjustment device and a light source module, and in particular to an optical element adjustment device and a light source module using the adjustment device. Background technique [0002] Please refer to figure 1 , which shows a schematic diagram of a conventional light source module. The light source module 100 is, for example, used in an optical projection device (not shown). The existing light source module 100 includes a lamp 110 , a lamp 120 , a light splitter 130 and a reflector 140 . The lamp 110 includes a wick 112 and a parabolic reflector 114 adapted to form a light beam 116 from the light emitted by the wick 112 . The lamp 120 includes a wick 122 and a parabolic reflector 124 , the parabolic reflector 124 is adapted to form a light beam 126 from the light emitted by the wick 122 . The beam splitter 130 is disposed in front of the entire light emitting section 118 , 128 of the lamps 110 , 120 , and the reflecto...
