Abstract
A low-voltage and high-power LED flame and explosion proof projection lamp comprises a flame-proof screen, a fixed frame, a lamp housing, LED lamp beads (or high-power LED luminescent modules), a heat dissipation body, a control power supply, a connecting wire, an input power lead, a fixing bracket, a cover body retaining screw, a lamp bead mounting circuit board and lenses. The projection lamp is characterized in that the flame-proof screen is arranged on the fixed frame; the fixed frame is fixed on the lamp housing via the cover body retaining screw; the LED lamp beads (or high-power LED luminescent modules) are welded on the lamp bead mounting circuit board; the lenses are arranged on the LED lamp beads; an LED lamp bead mounting plate is fixed inside a lamp shade via the fixing bracket; the heat dissipation body is arranged below the lamp bead mounting circuit board; the lamp bead mounting circuit board is connected with the control power supply via the connecting wire; and the input power lead is arranged at one end of the control power supply. The utility model has the beneficial effects that personal injury is totally prevented due to high safety performance, and the power is small and suitable for the operation under the condition of 3.5 v to 36 v AC&DC safe voltage; and the utility model has the advantages of safety, energy conservation, environmental protection and long service life.
Description
Technical field
The utility model relates to a kind of mine that is applicable to, the flame-proof explosion-proof of inflammable, explosive hazardous area illumination such as oil exploitation, smelting, chemical industry is thrown (general) light modulation, specifically a kind of low-voltage high-power LED flame-proof explosion-proof (general) light modulation.
Background technology
At present, flame-proof explosion-proof throwing (general) light modulation light emitting source in the technology is a conventional light bulb now, operating voltage height (220V), power consumption is big, and heating is high, the fault rate height, in case occur light fixture electric leakage or supply line's wearing and tearing in using, very easily cause personal injury accidents, and the power consumption height, maintenance cost is big, has also caused the waste of limited resources.
