Do you know the energy-saving principle of energy-saving lamps? Bona Fontaine tells you

Now every household has started to choose energy-saving lamps, but do you really understand the energy-saving principle of energy-saving lamps? Let Bonafontein and gojia.com tell you today.

The energy-saving lamp operates on the principle of gas discharge. Its name is called self-ballasted fluorescent lamp. In addition to white (cold light), there is still yellow (warm light). In general, under the same wattage, an energy-saving lamp is 80% more energy efficient than an incandescent lamp, with an average life expectancy of 8 times and heat radiation of only 20%. In a non-strict case, a 5 watt energy-saving lamp can be considered as an incandescent lamp equal to 25 watts, a 7-watt energy-saving lamp is about 40 watts, and a 9-watt is about 60 watts. The energy-saving lamp is also called compact fluorescent lamp (referred to as CFL lamp in foreign countries). It was first invented by foreign manufacturers in 1978. Because it has high luminous efficiency (5 times that of ordinary light bulb), it has obvious energy-saving effect and long life (it is ordinary light bulb). 8 times), small size, easy to use, etc., has been valued and welcomed by people of all countries and countries. In 1982, China first developed SL-type compact fluorescent lamps at the Institute of Electric Light Sources of Fudan University. Over the past 20 years, the output has grown rapidly. The quality has been steadily improved, and the country has promoted and used it as a national key energy-saving product (green lighting product). For quite a long period of time, some places and manufacturers blindly increased the energy-saving lamp project. Because of the lack of funds, technology, raw materials and processes, the product quality was not guaranteed. The imbalance of product quality, vicious bidding messed up the market, and did not produce according to the process requirements. The assembly plant used unqualified lamps and components to form a patchwork. The quality and price were low, which seriously damaged the reputation of energy-saving lamps and had low light efficiency. The short-lived life and poor consistency have caused the energy-saving lamps in the society to save energy and save money. This has brought about a great negative impact on the promotion of energy-saving lamps.

After nearly 20 years of continuous exploration and development, China's energy-saving lamp products have made great progress and improvement. Many products have approached or reached the advanced level of foreign countries. Due to the high quality and low price, the competitiveness in the international market is very high. Strong, but there are still a large number of energy-saving lamp manufacturers in the market. They ignore the laws and regulations of the country and disregard the interests of consumers. They are also producing a lot of energy-saving lamps that are not called "energy lamps" because of their quality and price. Low, each ex-factory price is only about 4~5 yuan. Consumers have limited identification of products. In rural areas and most cities, there is still a large part of the market, because most of the market in the market is occupied by low-end products. It makes it difficult for good energy-saving lamps to enter the market, which brings certain difficulties to the promotion of green lighting. However, with the improvement of residents' awareness of consumption and the understanding of energy-saving lamps, the market for good quality energy-saving lamps is in Every day, the market for energy-saving lamps with poor quality has shrunk day by day, which brings us hope and opportunity.

The energy-saving products we are talking about today are mainly for incandescent lamps. Ordinary incandescent lighting effects are about 10 lumens per watt, and the life expectancy is about 1000 hours. Its working principle is: when the light is connected into the circuit, the current flows through the filament, and the thermal effect of the current causes the incandescent lamp to emit continuous visible light and Infrared, this phenomenon can be noticed when the filament temperature rises to 700K. Because the filament temperature is high during operation, most of the energy is wasted in the form of infrared radiation. Because the filament temperature is high, evaporation is also fast, so the life is also Greatly shortened, about 1000 hours or so.

The energy-saving principle of the energy-saving lamp is mainly to heat the lamp filament through the ballast. At about 1160K, the filament starts to emit electrons (because some electron powder is coated on the filament), and the electron collides with the argon atom to produce an inelastic collision, argon. After the atom collision, the energy is absorbed and the mercury atom is struck. After the energy is absorbed, the mercury atom is ionized to emit ionization. 253.7nm ultraviolet light is emitted, and the ultraviolet light excites the phosphor to emit light. The temperature of the filament is about 1160K when the fluorescent lamp works, and the temperature is higher than that of the incandescent lamp. 2200K-2700K is much lower, so its life is also greatly improved, reaching more than 5,000 hours. Because it does not have the current thermal effect like incandescent lamps, the energy conversion efficiency of phosphors is also very high, reaching more than 50 lumens per watt.
