[0002] When using lights, COB light sources are usually used. COB light sources can provide better lighting and have the advantage of energy saving. For example, CN206449431U, an anti-glare COB downlight disclosed on the Chinese patent website, has the advantage of anti-glare. Although the device can be arranged on the optical lens in a concentric circle manner through an annular frosted layer, so that direct light is diffusely reflected on the annular frosted layer, which not only ensures the light transmittance, but also avoids eye discomfort caused by glare caused by direct viewing of the COB light source by the user, but when the COB downlight is irradiated, the light will scatter from all sides and cannot play a gathering role. Therefore, a constant current monochromatic COB light source is proposed to solve the problems mentioned in the above background. Utility Model Content
