High-frequency non-electrode LED lamps – a new green light source with high energy efficiency in the 21st century. The general working principles of this lamp is coupling energy into the bulb through the high-frequency induction magnetic field energy; forming plasma within the bulb via avalanche ionization; when excited atoms return to the ground state, they will send out UV rays (254nm), which is also called spontaneous emission; the fluorescent powder stimulated by UV rays, they will send out invisible light. Lacking of electrode and filament makes non-electrode LED lamps immune to the lifetime restrictions caused by light sources. The average service life of high-frequency non-electrode LED lamps is more than 60,000 hours, with a power factor higher than 98%, instant start and re-start, the efficiency of the entire system is no less than 63lm/W, color temperature between 2700K to 6500K, with CRI larger than 80, normal working temperature of -25℃-50℃. High-frequency non-electrode LED lamps have really good performances in many optical parameters. Their high efficiency and lower power consumption can save more than 60% energy compared with other traditional lamps.
Because of using solid amalgam, these lamps will not cause damages to the environment. 99% can be recycled, no flicker, low heat generation, led advantage no light pollution, long service life, no maintenance and frequent replacement, which saves a lot of human and material resources. High-frequency non-electrode LED lamps are widely used in factories, shopping malls, offices, classrooms, streets, parking lots, gas stations, stadium management, bridges, etc., especially used as green light sources in tunnels, subways, billboards, cold storage and other places where maintenance works are rather difficult.
Non-electrode lamp is not a new invention. As early as 100 years ago, American scientists invented similar lighting technology. However, due to all kinds of restrictions in technologies at that moment, non-electrode lamp can only stayed in the laboratory for a long time. Recently, scientists felt interested in them again and tried to combine this technology with LED lighting source (the 4th generation light source).
According to statistics, 20% of energy consuming of our country is from the lighting industry. If 1/3 of our current light sources replaced by LED lighting applications, then more than 150 billion degrees electricity will be saved every year. Estimated in accordance with the existing power energy structure, this assumption will reduce the carbon dioxide emission by 25 million to 43.2 million tons.
