Lens and light source module

Abstract

The invention discloses a lens used for light distribution and a light source module. The lens comprises an optical area integrally extending and used for light distribution and a driving power supply containing area located on one side of the optical area and used for containing a driving power supply. A light source containing groove is formed in the optical area. A driving power supply containing groove is formed in the driving power supply containing area. A magnetic mounting element is further arranged on the lens. The lens has the optical area used for secondary light distribution so that under the situation that light emitting units are reduced, an illuminating area and the light emitting effect which are required for an illuminating lamp still can be achieved by enlarging the illuminating angle of a light source through the lens; and therefore, the light source module provided with the lens has the advantages of being low in cost and capable of achieving a certain illuminating area and light emitting effect.

Description

[0001] This application is a divisional application of Chinese Invention Patent Application No. 201510698098.7 submitted on October 23, 2015, and the name of the invention is lens and light source module. technical field [0002] The invention belongs to the technical field of semiconductor lighting, and in particular relates to a lens and a light source module used in a lighting device. Background technique [0003] With the rapid development of semiconductor lighting technology, LED lighting fixtures, such as LED ceiling lamps, are more and more used in indoor spaces. Lambert’s light distribution, because the full width of the illumination angle of Lambert’s light distribution is about 120 degrees, therefore, after the LED light emitting unit emits light, a bright spot is formed on the ceiling lamp mask, or the transition between light and dark is uneven. Therefore, the existing LED lighting units are densely arranged on the light source substrate of the light source modul...

AI Technical Summary

Problems solved by technology

[0005] In addition, most of the existing LED lighting fixtures are integrated, and the components inside are assembled into LED lighting fixtures and installed on the indoor ceiling. When the components in the LED lighting fixtures, such as the light source or driving power supply, are damaged and need to be replaced, the above components are not easy to replace. Disassemble from the housing of the LED lighting fixture and reassemble it into the housing
