In addition to water, air, and food supplies, human life has always affected people's daily life. It has always been a sunrise and a sunset. Until 1879 Edison invented the light bulb (incandescent lamp), its principle is: When the light enters the circuit, the thermal effect of the current flowing through the filament causes the incandescent lamp to emit continuous visible light and infrared rays. This phenomenon rises to 700K at the filament temperature. It can be noticed that most of the energy is wasted in the form of infrared radiation due to the high temperature of the filament at work; at the same time, since the temperature of the filament is very high and the evaporation is rapid, the life is greatly shortened, about 2200 hours. Light efficiency is around 12 (Lm) per watt. In the past, the lighting system only paid attention to quantity, but today it has gradually become sophisticated and energy-efficient. Due to the widespread use of lighting technology and lighting fixtures, people's living standards have generally been raised, the demand for lighting equipment has increased dramatically, and the power consumption has also been expanded. Therefore, attention has been paid to the development of high-efficiency and high-quality lighting equipment. The electronic energy-saving lamp is mainly used to heat the lamp filament through a ballast. At about 1160K, the filament starts to emit electrons (a certain amount of electronic powder is fixed on the filament). The electronic collision collides with the elastic collision of argon atoms. After argon atom collision, it is obtained. After the energy hits the mercury atom, it absorbs energy, and the transition produces ionization; it emits ultraviolet light of 253.7nm, and the ultraviolet ray excites the phosphor. When the fluorescent lamp is working, the temperature of the filament is about 1160K, which is lower than the working temperature of incandescent lamp 2200K~2700K, so it The lifespan is also greatly increased to more than 8000 hours, and because it does not have the current thermal effect of incandescent lamps, it can reach 60 (lm) lumens per watt.

The size of the energy-saving lamp is similar to that of an incandescent lamp, and the interface with the lamp socket is also the same as that of the incandescent lamp. Therefore, the incandescent lamp can be directly replaced. The official name of the energy-saving lamp is a rare-earth trichromatic compact fluorescent lamp, which was born in the Netherlands in the 1970s. It was incorporated into the 863 promotion plan by the country and was first promoted in Shandong's Jiaodong Peninsula. The two factories that were the earliest to respond were Weihai Beiyang and Qixia Lamp Factory. However, due to the relatively high cost of the early stage, the promotion was more difficult. Guangdong, relying on its superior geographical location and relying on the country’s policy support, mass-produces energy-saving lamps with low-cost raw materials and sells them throughout the country. Because the early concept of energy-saving lamps was relatively ambiguous, the cost of energy-saving halogen-burning lamps produced in Guangdong was relatively low, and the price of the energy-saving lamps sold in the market was relatively low. Currently, 80% of the energy-saving lamps are produced in Guangdong, and 80% of them are in the energy-saving lamps. Zhongshan Guzhen production.
This kind of light source can only consume 1/5 to 1/4 of the power of an ordinary incandescent lamp under the premise of achieving the same output of light energy, which can save a lot of lighting power and costs, and is therefore called an energy-saving lamp.

The energy-saving lamp is actually a compact fluorescent lamp with a self-contained ballast. When the energy-saving lamp is ignited, the electronic ballast is first used to heat the lamp filament, and the filament starts emitting electrons (because some electronic powder is coated on the filament). The electron collision fills the argon atoms in the lamp tube. When the argon atoms collide, they gain energy and hit the internal mercury atoms. After the mercury atoms absorb energy, they transition to produce ionization, and the lamp tubes form a plasma state.
The voltage across the lamp is directly connected to the plasma and emits 253.7nm of ultraviolet light. The UV irradiates the phosphor. Since the temperature of the filament when the fluorescent lamp is working is about 1160K, it is much lower than the operating temperature of the incandescent lamp 2200K-2700K. Its life is also greatly improved, reaching more than 5,000 hours, due to its use of high-efficiency electronic ballasts, and the absence of current-thermal effects such as incandescent lamps, phosphors with high energy conversion efficiency, reaching more than 50 lumens per watt, so Save energy.
