Abstract
The present invention discloses a wide angle backlight lens which consists of lens mounting plate and lens body. Further, the upper outer surface of lens body is fixedly connected with the central position of the lower outer surface of lens mounting plate. Four sets of lens stands are installed near four corners of the upper outer surface of said lens mounting plate. Each set of said lens stands consists of two assembling stands. The luminous slot (4) is installed in the central position of the lower outer surface of said lens body (2) and lamp mounting slot (5) and reflective aperture (6) are installed in the central position of the upper outer surface of said lens mounting plate (1). A wide angle backlight lens described in the present invention is available for convergence and divergence of light rays according to actual needs, to improve the range of light diffusion and luminous intensity, hence realizing a higher uniformity of flares. Further, in respect of assembly, it could reduce the width of PCB, and direction detection is not required when the lens is travelling along the vibration plate rail, hence improving lens mounting efficiency and bringing a better application pros…
