Patent ID: 8523362

Claim:
An illumination system, comprising: a chip package, comprising: a first light-emitting chip capable of emitting a first light beam; a second light-emitting chip capable of emitting a second light beam; and a third light-emitting chip capable of emitting a third light beam, wherein the first light-emitting chip, the second light-emitting chip, and the third light-emitting chip are arranged in a row, and the first light beam, the second light beam, and the third light beam have mutually different colors; a first dichroic film disposed in the light paths of the first light beam, the second light beam, and the third light beam; a second dichroic film disposed in the light paths of the second light beam and the third light beam; and a third dichroic film disposed in the light path of the third light beam, wherein the first dichroic film, the second dichroic film, and the third dichroic film are numbered for the proximity to the chip package, are not parallel to each other, and do not cross each other, and the first dichroic film is capable of reflecting the first light beam and transmitting the second light beam, the second dichroic film is capable of reflecting the second light beam, the first dichroic film and the second dichroic film are capable of transmitting the third light beam, the third dichroic film is capable of reflecting the third light beam, and the first light beam, the second light beam, and the third light beam form an illumination light beam as the first light beam, the second light beam, and the third light beam respectively leaving the first dichroic film, the second dichroic film, and the third dichroic film, and wherein the light paths of the first, the second, and the third light beams respectively are parallel to each other as the first, the second, and the third light beams are in the process of leaving the first, the second, and the third dichroic films.
