Abstract

According to the lens and the light-emitting device, the first area of the top face of the lens comprises the inner refraction face which can transmit part of light rays emitted by a light source to the outside of the lens, and therefore the top face of the lens can emit light to illuminate the area above the lens, and the problem that a dark area is formed in the position where the lens is located is avoided. Meanwhile, the first area is also provided with the inner reflecting surface, and the inner reflecting surface can reflect part of light of the light source to the side surface of the lens to be emitted, so that the problem that the light right above the lens is too bright can be avoided, and the overall light emitting uniformity of the light-emitting device is improved.

Description

technical field [0001] The present invention relates to the field of optics, in particular to the field of light beam control, in particular to a lens and a light emitting device. Background technique [0002] In order to increase the light emitting angle, a wide-angle optical lens is installed in the light emitting device, and the wide-angle lens cover is arranged above the LED to change the optical path of the light emitted by the LED and allow the light emitted by the LED to spread in more directions. However, at present, the top surface of the wide-angle lens is usually a total reflection surface, which will cause almost no light to reach the top of the light emitting device, thereby forming a dark area at the position of the light emitting device, affecting the uniformity of light emission of the light emitting device. [0003] Therefore, how to solve the problem of uneven light emission of the light emitting device is an urgent problem to be solved at present. Conten...
