Description

Technical Field

[0001] The utility model relates to the field of industrial and mining lamps, in particular to an energy-saving industrial and mining lamp with good heat dissipation effect. Background Art

[0002] Industrial and mining lamps are a general term for lamps used in factories, mines, warehouses, and high-bay production areas. General lighting lamps are usually evenly arranged above or on the side walls of the work area to illuminate the entire work surface. They require high-power incandescent lamps, halogen tungsten lamps, high-intensity gas discharge lamps, or a large number of fluorescent lamps. In addition, there are also relatively energy-saving high-power LED industrial and mining lamps.

[0003] In the prior art, the places where mining lamps are used generally need to remain bright for a long time, and the mining lamps need to be illuminated for a long time. However, long-term operation will increase the temperature of the LED light-emitting components in the lamp body, thereby reducing the service life of the mining lamp. Conventional mining lamps will be evenly spaced to provide some heat dissipation fins to improve the heat dissipation effect of the mining lamps. However, for mining lamps that are used for a long time or high-power mining lamps, the heat dissipation effect still cannot meet the demand, which not only easily leads to a decline in the performance of the mining lamps, but may even cause malfunctions and damage.

[0004] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0031] like Figure 1 and Figure 3As shown, the backlight surface of the LED chip 5 is connected to the heat sink 7 through the thermally conductive base 6. A through hole 70 for assembling the thermally conductive base 6 is provided in the middle of the heat sink 7. The thermally conductive base 6 is used to absorb the heat generated by the LED chip 5 and transfer it to the heat sink 7. The heat sink 7 is provided with a plurality of heat dissipation fins 71 arranged at intervals along the circumferential direction. An air guide gap 711 is formed between two adjacent heat dissipation fins 71. The heat dissipation fan 8 is provided at one side end of the heat sink 7 away from the LED chip 5.
