Abstract

The invention provides a light-emitting device light guiding lens and a light-emitting device and relates to the technical field of semiconductor devices. By means of a first hammer light guiding groove and a second light guiding groove arranged in the circumferential direction, light emitted by a light source can be distributed, and refraction or total reflection of light occurs at an interface of the light guiding lens, so that the original propagation direction of the light changes, the coverage range of the light radiated from the light-emitting device light guiding lens is wider, and theillumination range of the light source is larger. The light-emitting device light guiding lens is simple in structure, low in manufacturing cost, and beneficial to miniaturization and ultra-thinness of the light source.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a light guide lens of a light emitting device and a light emitting device. Background technique [0002] In modern lighting applications, light-emitting diode (LED) light sources are gradually replacing traditional light sources due to their advantages of energy saving, high efficiency, and good stability. need. However, when optical devices such as reflectors or lenses are added to control the light emitted by LEDs, the overall device needs to occupy a large space, which is not conducive to the development of miniaturization and ultra-thinning of lamps. Contents of the invention [0003] In view of this, the present invention provides a light guide lens for a light emitting device and a light emitting device, which have a simple structure and can achieve better control over light emitted by a light source. [0004] The technical scheme provided by the invention is as ...
