Abstract
The present invention relates to a wearable mining lamp with uniform auxiliary lights, comprising a main light source and a main lamp cup. The mining lamp further comprises auxiliary light sources and auxiliary lamp cups for mounting the auxiliary light sources; the side wall of the auxiliary lamp cup has a reflecting effect, the reflecting surfaces are flat surfaces, and the side wall is in the form of a rearward tapering horn. The miniature lamp cup structure disclosed by the present invention can regulate the low-beam projection in a predefined area to provide uniform illumination without light spots and shadow interferences, so as to provide a high-quality illumination environment for low-beam operation and meet the requirements of close-range observation or operation.
