Brightness-adjustable LED mining lamp

Abstract

The invention discloses a brightness-adjustable LED mining lamp. The brightness-adjustable LED mining lamp comprises a mining lamp body and a driving power supply, wherein the driving power supply isarranged inside the mining lamp body. The mining lamp body comprises a mining lamp shell, a light-emitting device, a heat dissipation device, an adjusting device and a protection device, wherein the interior of the mining lamp shell is provided with a heat dissipation cavity for containing the heat dissipation device and a driving cavity for containing the driving power supply, the side, back on to the driving power supply, of the heat dissipation device is connected with the light-emitting device, and the adjusting device is connected with the light-emitting device and the driving cavity; andthe driving power supply is electrically connected with the light-emitting device, the heat dissipation device and the adjusting device. The brightness of the LED mining lamp during working can be improved, the intensity of the illumination can be automatically adjusted when the temperature is too high so as to decrease the temperature of the LED mining lamp, cooling can be carried out in real time, and elements in the LED mining lamp are prevented from damage; and when the voltage is unstable or short circuit occurs, a controller controls the LED mining lamp to stop working, so that the personal injury is prevented, the service life of the LED mining lamp is prolonged, and the LED mining lamp is convenient to use.

Description

technical field [0001] The invention relates to the technical field of lighting tools, in particular to an LED industrial and mining lamp with adjustable brightness. Background technique [0002] People who work in large factories will use a series of lighting tools. The lighting tools used in many factories are traditional incandescent lamps, high-pressure sodium lamps, etc., but these lighting tools consume a lot of energy and consume a lot of unnecessary energy. And the lifespan is short. With the continuous development of lighting technology, LED technology is also continuously applied in lighting tools. At present, many factories use LED technology lighting tools in operation, but the existing LED lamps have poor heat dissipation performance during use. If the temperature is too high, there will be no protection function to damage the original components such as the LED lamp and the driving power supply, and the brightness of the LED lamp cannot be increased, and many...

And the lifespan is short. With the continuous development of lighting technology, LED technology is also continuously applied in lighting tools. At present, many factories use LED technology lighting tools in operation, but the existing LED lamps have poor heat dissipation performance during use. If the temperature is too high, there will be no protection function to damage the original components such as the LED lamp and the driving power supply, and the brightness of the LED lamp cannot be increased, and many LED lamps are too concentrated to emit light, have poor uniformity, and are overweight.
