LED is actually a light-emitting diode. Its main component is a semiconductor that converts electrical energy into light energy, connects it to a circuit board with silver wires or gold wires, and is surrounded by an epoxy seal.
The main luminescent material for energy-saving lamps is still tungsten wire. Its working principle is that when the tungsten wire is energized, it will generate heat. At this time, electrons will be generated, and then a certain technical means will be used to accelerate the electrons. The lamp of the CFL is designed as a vacuum filled with mercury, ie mercury. The accelerated electrons interact with the vaporized mercury atoms, thus producing ultraviolet light. A fluorescent substance is coated in the CFL tube, and when ultraviolet light is irradiated onto the fluorescent substance, light is emitted.
The difference between LED lights and CFL is different from the principle of lighting, and there are also many differences in environmental protection, energy saving, service life, and stability. Compared with CFL, LEDs are energy efficient. The energy consumed by LEDs is one-fourth that of CFL. This is because ordinary CFL still need to consume a part of the energy, which can be converted into heat, while LED lamps do not need to do so.
LED lights are more environmentally friendly. Mercury is one of the indispensable luminescent materials in energy-saving lamps. If it is used for a long time, there will be gaps in the sealing performance of CFL. Mercury will be volatilized into the air, causing pollution to the air and affecting human health. LED lights do not have such problems, it is safer and more environmentally friendly.
From the perspective of service life, LED lamps to have a longer service life. The quality of qualified LED bulbs produced by regular manufacturers can reach 50,000 to 80,000 hours. If it is an energy-saving lamp, its service life is only 6000 to 10,000 hours. LED lights are stronger than CFL in terms of seismic and lightning protection. Continuous switches caused by voltage instability have far less impact on LED lights than CFL. If the CFL is switched frequently, it will reduce its service life.
