The main luminescent material of energy-saving lamps is still tungsten wire. The principle is that after the tungsten wire is heated, it will generate electrons, and use certain technical means to accelerate the electrons. The tubes of energy-saving lamps are designed as a vacuum, filled with mercury, or mercury. The accelerated electrons interact with the evaporated mercury atoms to produce ultraviolet light. A fluorescent substance is coated in the energy-saving lamp tube, and ultraviolet light irradiates the fluorescent substance to generate light.
LED lamps are formed by connecting LED lamps in series or parallel. These LED lamps are composed of light-emitting diodes. Under the action of an integrated circuit chip, the AC 220V power supply is converted into direct current with voltage and current that can match the LED set. Meet the requirements of the LED lamp bead assembly, so that it can emit light normally.
The previous articles have mentioned the meaning of LED parameters, and the unit of measuring the brightness of the light source is called “luminous flux“.
Luminous flux: 1W LED lamp = 3W energy-saving lamp = 15W incandescent lamp.
Now the light effect of some superb LED lights can even reach 120Lm / W
It can be seen that the brightness (luminous flux) of LED lamps is much higher than that of energy-saving lamps and ordinary incandescent lamps.
3.Energy consumption comparison:
In the case of the same luminous flux, the energy consumption of an LED lamp is only 1/4 of that of an energy-saving lamp. This is because a small part of the energy consumed by energy-saving lamps will be converted into heat, and LED lamps do not have this problem. In daily use, the 10W LED lamp is used for 100 hours and consumes only 1 degree of electricity, which is far superior to energy-saving lamps.
Since the LED lamp does not have the problem of filament fuse, the life of the general LED lamp can be used for more than 20,000 hours (the light decay phenomenon will gradually occur when used for more than 20,000 hours), and the life of some special LED lamps can reach 50,000. hour. And the life span of general energy-saving lamps is about 5000 hours, and the highest ones are more than 8000 hours. Comparing the two, we can see that the life of the LED lamp is much longer than that of the energy-saving lamp, which also saves us the trouble of frequently changing the bulb.
5.Environmental protection comparison:
Energy-saving lamps are filled with mercury, mercury and other harmful substances. With the use of time, the sealing of energy-saving lamps will have gaps, and the mercury in them will evaporate into the air, causing environmental pollution. LED lights have no problems in this regard, and the materials used are safe and environmentally friendly.
As of now, LED technology is very mature, and the price is more expensive than traditional energy-saving lamps, but it is completely acceptable under the premise of long life and energy saving.
