LED energy-saving lamp knowledge extension

Simply put, lamps with different illumination principles have different efficiency in converting electrical energy into light energy, so the power consumption is different.

The working principle of incandescent lamp is to convert electric energy into heat energy, and then radiate light energy by heat energy. Its working process is to heat the temperature of the filament to 2000 °C or higher by current, just like the red iron can emit light. Come. In this process, a large amount of electrical energy is converted into heat and wasted, and only about 10% of the electrical energy can be converted into useful light energy.

The working principle of the fluorescent lamp is: in a closed gas discharge tube containing argon (or krypton) gas and mercury, the temperature of the filament is heated to about 1000 ° C by electric current, and the filament coated with the electronic powder starts to emit electrons and collide with argon. The atom acquires energy, and the argon atom collides with the mercury atom to cause ionization. The ultraviolet ray excites the phosphor coated on the wall of the gas discharge tube to emit white light. The electro-optical conversion efficiency of the fluorescent lamp is about 25%, which is about the same power tungsten lamp. double.

LED illumination, ie LED illumination, is a semiconductor device that can directly convert electrical energy into light energy. After power-on, it converts 90% of the electrical energy into light energy. The remaining part of the electrical energy generates a small amount of thermal energy when the semiconductor device is working, and the electro-optical conversion efficiency Up to 90%. In short, the LED does not need filament heating, is a cold light source, distinguishes the working principle that the other lamps are inevitably heated, and abandons the process of converting electrical energy into thermal energy and then converting it into light energy, directly converting electrical energy into light energy, in the case of generating the same brightness. The least energy is consumed. Therefore, LED energy-saving lamps are more energy efficient than other lamps.
