First, a brief history of the development of electric light source In 1879, the United States Edison invented a practical use of carbon filament incandescent lamp, so that humans enter the era of electro-optical lighting from the long fire lighting era.
In 1907, the first tungsten incandescent lamp appeared.
Inflatable incandescent lamps appeared in 1912, and their luminous efficacy and life were higher than those of non-inflatable incandescent lamps.
In 1932, Philips launched a low pressure sodium lamp.
In 1938, Philips produced the first fluorescent lamp. Its luminous efficacy and lifespan were more than three times that of incandescent lamps. This was a major breakthrough in electric light source technology.
In the 1940s, high-pressure mercury lamps entered the practical stage.
In the 1950s, the introduction of tungsten halogen lamps with small volume and light decay changed the state of slow progress in the development of thermal radiation light sources. This is another major breakthrough in electric light source technology.
In the 1960s, neon lights, metal halide lamps, and high pressure sodium lamps appeared one after another.
In 1972, Philips launched the second generation of thin-tube (T8) energy-saving fluorescent lamps and fluorescent high-frequency electronic ballasts. Afterwards, compact and compact fluorescent lamps, ultra-low-mercury energy-saving fluorescent lamps, low-power high-pressure sodium lamps, low-power metal halide lamps, neon lamps, high-brightness light-emitting diodes, ultra-thin tube cold-cathode tubes, and multi-functional electronic ballasts have been successively It emerged and it flooded into the market, making electric light sources compact and highly efficient. A new era of energy conservation, environmental protection, standardization, and electronics.
In the past two years, with the advent of ultra-high brightness white LEDs, the application of LEDs in the lighting field has become possible. In the context of rising global energy shortage worries, the prospects of LED in the lighting market have attracted worldwide attention. According to forecasts of international authoritative organizations, in the next 10 years, LED will become the most promising new light source to replace incandescent lamps, halogen lamps, and energy-saving fluorescent lamps. In the 21st century, it will enter the era of new lighting sources represented by LEDs (called the first Four generations of new light source era). It has also been pointed out that high-brightness LEDs will be one of the greatest inventions of mankind after Edison invented incandescent light bulbs.
China's electric light source industry is developing rapidly. At present, China's electric light source production has leapt to the top in the world, and its quality has also rapidly increased. International standards have been adopted or equivalently adopted. Many electric light source products, such as metal halide lamps, high pressure sodium lamps, T5T8 fluorescent lamps, ring fluorescent lamps, compact energy-saving compact fluorescent lamps, double spiral lamps, cold cathode fluorescent lamps, tungsten halogen lamps, tungsten halogen automotive lamps, PAR series lamps High-brightness light-emitting diodes and supporting raw materials, components, lamps, lamps, filaments, etc. have reached or approached the world's advanced level, and a large number of exports around the world.
