It has long been known that the electrodeless lamp has the advantages of long life, high Energy Saving and no light pollution. It is a truly green light source, but it is puzzling that such a good product is hard to find in the home lighting market. What? With such questions, the reporter visited Mr. Huang Weizhong, Chairman of Shenzhen Zhonghuixing Electrode Lamp Co., Ltd. and Mianyang Zhonghuixing Optoelectronics Technology Co., Ltd.
Why is the high frequency electrodeless lamp born?
As an electric light to replace the traditional flame-type luminaire, the emergence of incandescent lamps is a fly-by and revolution in the history of human lighting. There is no need to talk about its benefits, but its disadvantages are often overlooked. Huang Weizhong first introduced to reporters some of the problems and current status of lighting products commonly used by people in lighting technology. He said that looking back at the 1930s and 1940s, especially in the vast rural areas, kerosene lamps and even soybean oil lamps are the most commonly used lighting tools. Although these light sources are original, there is no stroboscopic flash for 50 weeks of AC power, and there is no glare of glare. Everyone has good eyesight. Since the emergence of tungsten incandescent lamps and later new light sources such as Fluorescent Lamps, sodium lamps, and metal halide lamps, children have been exposed to light pollution such as stroboscopic and glare since the day of birth. When they were in elementary school at the age of six or seven, many people The vision has been compromised. This is why many middle and primary school students have poor eyesight and wear glasses. This is unimaginable for people born in the 1930s and 1940s. Therefore, in order to obtain a high luminous rate, high color rendering, high stability, long life, no stroboscopic, no glare, the real green light source, people began to explore and search infinitely, in this tide, High-frequency electrodeless lamps came into being.
True green lighting
Huang Weizhong introduced the working principle and characteristics of the electrodeless lamp to the reporter. The high-frequency electrodeless lamp is composed of a high-frequency power source, a power coupler and a bulb body. The high-frequency power generated by the power source is transmitted to the power coupler via the feeder, and the power coupler outputs an electromagnetic field to ionize the gas in the bulb to form a plasma. The plasma excites the three primary color phosphors on the bulb to emit visible light after being subjected to an electromagnetic field. Since the high-frequency electrodeless lamp has no filament or electrode, it is not directly powered by AC 50-week mains, but is converted from high-frequency power of 2.65 MHz to the induction lamp, which gives it many advantages.
First, the induction lamp has no 50-week stroboscopic light, the phosphor light is soft, the color rendering index is greater than 80, close to the sunlight, so there is no light pollution. Second, we usually have this experience when using incandescent lamps, incandescent The filament of the lamp is easy to blow, and once the filament is broken, the whole bulb is also scrapped, and the electrodeless lamp has no filament and electrode, which makes it have a service life of up to 60000H; the third is excellent circuit design, which makes the electrodeless lamp high. Power factor (≥0.98), low heat consumption, high luminous efficiency, etc., therefore, the safety hazard to the power supply system is small, electromagnetic interference is small, and power is saved. An 85W induction lamp, the lighting effect is equivalent to 500W incandescent lamp, saving 80%; Fourth, there is no liquid mercury in the electrodeless lamp that harms the human body and the environment. Numerous of these advantages add up to make the electrodeless lamp a quality environmentally friendly, true green lighting solution.
