Direct current multi-purpose large-power LED lighting energy-saving lamp of microcomputer

Abstract

The invention relates to a direct current multi-purpose large-power LED lighting energy-saving lamp of a microcomputer, belonging to the field of power lighting. The lamp comprises a lamp body (1), a control circuit board (5), an LED light emitting device (8) and a reflecting cover body (9) and the like; the positive electrode and the negative electrode of a power line (2) are connected with the positive electrode and the negative electrode of a direct current power supply; the other end of the power line (2) is connected with the control circuit board (5); the LED light emitting device (8) is arranged on a radiating plate (6); a temperature sensor (12) is arranged at the back of the control circuit board (5); the control circuit board (5) and the radiating plate (6) are arranged in a shell (4) at interval; the reflecting cover body (9) is arranged at the lower end of the radiating plate (6); and the waterproof transparent cover (10) is arranged at the bottom end of the shell (4). The lamp has energy-saving efficiency, can save energy by 80 percent compared with the incandescent lamp under the condition of equal lighting effect, and has long service life which is 33.3 times as that of the incandescent lamp under the environment of equal power energy use, and the like.

Description

technical field [0001] Microcomputer DC multi-purpose high-power LED lighting energy-saving lamps. It belongs to the field of electric lighting. Background technique [0002] At present, at home and abroad, when the AC power fails, or in the absence of AC power, the multi-purpose lighting lamps used mainly include: DC inverter AC circuit to convert the DC voltage of the battery into AC voltage for power supply. The incandescent lamps with tungsten filaments, or the energy-saving lamps with tungsten filaments that start phosphors to emit light, and the energy-saving lamps with tricolor phosphors that emit light. Their common feature is the use of tungsten filament luminescent material and luminescent technology. The power supply adopts DC inverter AC technology. Its disadvantage is that the tungsten filament luminescent material converts 90-97% of the electric energy into heat consumption and waste, and at the same time, the DC inverter equipment also generates a large amo...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the tungsten filament luminescent material converts 90-97% of the electric energy into heat consumption and waste, and at the same time, the DC inverter equipment also generates a large amount of heat dissipation and waste.

As a result, the battery needs a large capacity, large volume, and many charging times, which consumes and wastes scarce power resources

[0003] To sum up, at present, all kinds of multi-purpose lighting lamps have low efficiency of electric energy conversion, high power consumption, large battery loss, and short service life, resulting in a large amount of waste of power resources and waste of battery materials.
