The LED lamp beads used in the explosion-proof lamp of the utility model have long service life, low energy consumption, large heat dissipation area of the heat dissipation plate, and good thermal conductivity; , the LED lamp bead is in a non-energized state. When the environment is insufficiently illuminated under natural conditions, the LED lamp bead is in a power-on state, thereby realizing the automatic switch of the LED lamp bead lighting, and under the premise of ensuring the light that meets the environmental needs, The pulse power supply circuit is preferred, so that only half of the LED lamp beads are allowed to emit light at the same time, and work alternately according to the pulse frequency, which reduces the total heat generation of the lamp body; in addition, the temperature of the cooling plate is collected in real time through the temperature sensor. When the temperature exceeds the limit, the explosion-proof intelligent fan will be activated immediately to speed up the air flow in the light box, super cooling the cooling plate, and returning the temperature in the box to the set level. circuit to reduce the total heat generation of the lamp body.

The explosion-proof lamp of the utility model is convenient to use, has a long service life, is low in energy consumption and is safe, and has good self-adaptive control effects on environmental illumination and temperature state changes.
