Abstract

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 the LED chips can be effectively reduced.

Description

technical field [0001] Embodiments of the present invention relate to optoelectronic technology, in particular to a semiconductor light source industrial and mining lamp. Background technique [0002] High bay lamp is a kind of lighting equipment widely used in factory workshops, mine working surfaces and warehouses. Since the space height of these places is usually high, and there are certain special requirements for brightness and light irradiation direction, the power of high bay lights is usually high, and the light irradiation angle is small. The light source of traditional industrial and mining lamps usually uses incandescent lamps, tungsten halogen lamps or high-pressure gas discharge lamps. These lamps generally have the defects of high energy consumption and short service life. [0003] With the advent of the fourth-generation light source-semiconductor light source, the development of energy-saving lighting products has achieved a new leap. This kind of semicond...
