Abstract:
1. A mixed light apparatus comprising: a first light reflecting element having a first emanating point and a first focal point; a first light source disposed at the first focal point; a second light reflecting element having a second emanating point and a second focal point; a second light source disposed at the second focal point; a third light reflecting element having a third emanating point and a third focal point; and a third light source disposed at the third focal point; wherein the first light reflecting element, the second light reflecting element, and the third light reflecting element intersect with each other and form a light emitting surface at intersections between them; and wherein the first emanating point, the second emanating point, and the third emanating point overlap one another and are disposed on the light emitting surface; wherein the first emanating point and the first focal point are on a first axis, the second emanating point and the second focal point are on a second axis, and the third emanating point and the third focal point are on a third axis; the first axis and the light emitting surface define a first inclined angle ranging from about 40 degrees to about 70 degrees; the second axis and the light emitting surface define a second inclined angle ranging from about 40 degrees to about 70 degrees; the third axis and the light emitting surface define a third inclined angle ranging from about 40 degrees to about 70 degrees.
