Problems solved by technology

However, the lens of the light source in the prior art is directly installed in the lamp holder, and the lens is fixedly installed on the lamp holder, and its angle and height cannot be adjusted. The light source of the height or angle of the lens must be equipped with some external regulators to achieve height adjustment. This type of structure is complex, troublesome, and often has a large volume, which does not meet modern life and needs.

Abstract

The invention discloses a light source capable of adjusting a light-emitting angle. The light source capable of adjusting the light-emitting angle comprises a lamp base, a chip on board (COB) light source installed on the lamp base and a lens installed and matched with the lamp base and located above the COB; the lamp base is provided with a lens cup installed and matched with the lens; the COB is installed on the bottom of the lens cup; and the lens can be upwards and downwards moved relative to the lens cup so as to adjust the height distance of the lens. The light source capable of adjusting the light-emitting angle is capable of adjusting the height distance between the lens and the COB light source through rotating the lens, changing the light-emitting angle, and changing the illumination lighting effect; and after the height of the lens is adjusted, the connection between the lens and the lamp base is stable and is not easily loosened.

Description

technical field [0001] The invention relates to a light source with adjustable light emitting angle, in particular to a light source with adjustable light emitting angle which realizes adjusting the light emitting angle by adjusting the height of a lens and a COB light source. Background technique [0002] Existing COB light sources generally have the advantages of high brightness and wide irradiation angle, and are increasingly popularized and used. However, the lens of the light source in the prior art is directly installed in the lamp holder, and the lens is fixedly installed on the lamp holder, and its angle and height cannot be adjusted. The light source with lens height or angle must be equipped with some external regulators to achieve height adjustment. This type of structure is complex, troublesome, and often bulky, which does not meet modern life and needs. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the p...
