Abstract

The invention provides a high-power flashlight. The high-power flashlight comprises a light emitting assembly and a battery assembly and further comprises a heat dissipation assembly arranged between the light emitting assembly and the battery assembly. The heat dissipation assembly is provided with an air inlet. An outer shell of a lamp body is provided with an air outlet, an LED lamp panel is provided with a plurality of vent holes. The heat dissipation assembly comprises a function bin, a drive plate and an air blowing device, wherein the drive plate is arranged inside the function bin and connected with a battery, the air blowing device is controlled by the drive plate, and the drive plate is provided with a temperature control switch. According to the high-power flashlight, a heat dissipation structure through which heat dissipation of a light source of the high-power flashlight can be facilitated is additionally arranged in a traditional high-power flashlight structure, the forced air convection can be achieved through the additionally arranged heat dissipation assembly to physically cool the LED lamp panel serving as the light source, and therefore an LED lamp chip cannot be burned out, and the high-power flashlight can be used for lighting in a high-power mode for a long time.

Description

technical field [0001] The high-power flashlight of the present invention particularly relates to a high-power flashlight with a fan. Background technique [0002] At present, high-power flashlights (such as flashlights above 10W) ​​are suitable for search and rescue, caving, hunting and daily lighting occasions, and these occasions need to provide high-power light for a long time. However, the problem of heat dissipation during high-power lighting is basically to rely on the heat dissipation ribs on the structure to dissipate heat through natural wind. Due to the space limitation of the flashlight, it is impossible to make large-area heat dissipation ribs, and there are no forced convection heat dissipation structures. Therefore, It cannot meet the heat dissipation requirements of high-power flashlights for a long time. Therefore, many high-power flashlights are equipped with high-power light-emitting gears. The high-power light of this kind of flashlight can only last for...
