Abstract

The invention discloses an optical lens and a light-emitting device with the optical lens. The optical lens comprises a first lens part and a second lens part which are in overlapping connection with each other in a top-to-bottom direction, wherein the first lens is transparent; the second lens part is non-transparent; a light through hole is formed in the second lens part and passes through the top and the bottom of the second lens part; the light through hole is used for aligning a light source of the light-emitting device at the lower part; and the cross section area of the light through hole is smaller than or equal to the light-emitting area of the light source. Through the technical scheme, the universality of the optical lens applied to the light-emitting device can be improved.

Description

technical field [0001] The invention relates to the technical field of light emitting devices, in particular to an optical lens and a light emitting device. Background technique [0002] In the currently commonly used point light sources, especially LEDs, an optical lens is usually required to convert the point light source into a surface light source. However, in the current design of optical lenses, due to the differences in the near-field optical distribution of different types of LEDs, the optical lenses used to match LEDs are also different, that is, a certain type of LED can only be used with the same Corresponding optical lenses with a specific optical path are matched and used, which makes matching between LEDs and optical lenses difficult, and the versatility of optical lenses is low. Contents of the invention [0003] The main purpose of the present invention is to provide an optical lens, aiming at improving the versatility of the optical lens used in light emi...
