Beschreibung
Zusammenfassung:	The invention discloses a semiconductor light source mining lamp. The lamp comprises a radiating device and an aluminum substrate, wherein the surface of the aluminum substrate is provided with light emitting diode (LED) chips; the radiating device comprises a phase change heat transfer cylinder which forms a sealed cavity; the sealed cavity is filled with liquid working medium which is subjected to phase change when heated; the outer wall of the phase change heat transfer cylinder is provided with radiating fins; and the phase change heat transfer cylinder is arranged on the surface of the aluminum substrate and is away from the LED chips. In the lamp, a technical means of phase change heat transfer is adopted; and a phase change process of the liquid working medium is utilized to quickly, uninterruptedly and circularly transfer heat, and the heat produced by the LED chips is quickly transferred to a shell of the phase change heat transfer cylinder and the radiating fins, so that the junction temperature of
