Publication number: 20100103683Abstract: A diffusing lens is described. The diffusing lens includes an emitting plane and an incident surface including two first refraction portions and two third refraction portions. The two first refraction portions are symmetrically arranged on both sides of the diffusing lens on opposite sides of a central axis of the diffusing lens. The two third refraction portions are symmetrically arranged near the central axis of the diffusing lens and on opposite sides of the central axis of the diffusing lens. The angle between the first refraction portion and the emitting plane is larger than the angle between the third refraction portion and the emitting plane. Thus, by directing some more of the central axis light beams away from the central axis, the light is more uniform after passing through the diffusing lens.Type: ApplicationFiled: February 20, 2009Publication date: April 29, 2010Applicant: CHI MEI COMMUNICATION SYSTEMS, INC.Inventor: CHING-SEN TSAI
