Beschreibung
Zusammenfassung:	A small LED mining lamp comprises a shell, an LED light source, lamp cups and a battery. The LED light source is provided with a main light source and a pair of auxiliary light sources. The main light source and the auxiliary light sources are independent of one another and separated from one another. The main light source and the auxiliary light sources are provided with the independent main lamp cup and the independent auxiliary lamp cups correspondingly. The front end face of the main light cup is circular. The front end faces of the auxiliary lamp cups are ovals with the eccentricity being 0.4-0.9. The front surface of the main lamp cup is a smooth reflecting surface. The front surfaces of the auxiliary lamp cups are rough reflecting surfaces. Circular holes formed in the bottom of each auxiliary lamp cup and surrounding the corresponding light source deform in a non-equal-proportional mode to form the oval end face of the auxiliary lamp cup. The mining lamp provided by the invention pursues high safety,
