????The electrodeless lamp from birth to the present, has been 100 years time. Long years, the long river, the three time points record world

On the development of the induction lamp technology.

????In 1 907, U.S. scientists PC.Hewitt apply the principle of induction lamp patent Thompson (JJThomson) Theis

Qin (Tesia) who invented the high-frequency induction lamp. However, due to restrictions on the level of the electronics technology, such lamps can only be in the experiment

Rooms exist, did not enter the market.downlight led

????In 1991, Japan s Panasonic first introduced the Everbright electrodeless fluorescent lamps and put into the Japanese market, then 27w of

Everbright electrodeless fluorescent light efficiency 37lm / w, the average life expectancy of 40,000 hours. In the same year, Philips QL electrodeless fluorescent lamps

Also put into the market. QL electrodeless fluorescent light efficiency reached 70lm / w, the average life expectancy of 60,000 hours.

????In 1994, GE launched GENURA electrodeless fluorescent lamps, a ballast and lamp integrate d compact electrodeless fluorescent

Similar structure with Philips QL electrodeless fluorescent lamps, similar to the shape and reflective type incandescent operating frequency selection of the 2.65 M light efficiency

Is 50lm / w, life is 15,000 hours. Osram Introduces then ENDURA electrodeless fluorescent. ENDURA electrodeless fluorescent lamps operating frequency

Rate is 300KHz, the luminous efficiency of 75lm / w, the average life expectancy of 60,000 hours.
