Abstract:
1. A light source adjusting device for a projection system, the projection system further comprising a light source module which is capable of providing a first beam with a first wavelength, the light source adjusting device comprising: a first angle selecting layer for receiving the first beam and allowing a first portion of the first beam to pass therethrough to form a second beam having the first wavelength, in which the first portion is a portion of the first beam that is less than an incident angle; a wavelength converting layer for receiving the second beam transmitted from the first angle selecting layer and converting the second beam having the first wavelength into a third beam having a second wavelength; and a second angle selecting layer for receiving the third beam and allowing a third portion of the third beam to pass therethrough to form a fourth beam having the second wavelength, in which the third portion is a portion of the third beam that is less than an emergence angle; and the light source module comprises:
