Three time points

    Endless lights from the birth to the present, has been through more than 100 years of time. In the long years, there are three major points of time to record the development of the world's most pole lamp technology.

    In 1907, the United States scientists PC.Hewitt application of the principle of the principle of the induction of non polar light, Thompson (J.J.Thomson), Teski (Tesia), who invented the high-frequency non polar light. However, due to the limitations of the level of electronics technology, the lights can only exist in the laboratory, did not enter the market.

    In 1991, the Japanese Panasonic Corp first introduced the Everbright fluorescent lamp and put into the Japanese market, at that time the Everbright 27W fluorescent light efficiency is 37lm/w, the average life expectancy is 40000 hours. In the same year, QL company's Philips fluorescent lamp is also put into the market. QL fluorescent lighting effect reached 70lm/w, the average life expectancy is 60000 hours.

    1994, Ge launched a GENURA electrodeless fluorescent lamp with, which is an integration of ballast and lamp compact electrodeless fluorescent lamp and its structure and Philips QL no electrodeless fluorescent lamp is similar, similar to the shape and reflectance type incandescent lamp, working frequency also use the 2.65M light effect of the is 50lm/w. Life is 15000 hours. Then Osram company launched the ENDURA fluorescent lamp. The working frequency of the ENDURA fluorescent lamp is 300KHz, and the light efficiency is 75lm/w, the average life span is 60000 hours.

    Chinese enterprises from the water to the scale of the use of

    1998, Hebei gem group in the laboratory to light up the country's first non polar lights. Subsequently, the gem Group officially entered the field of high frequency nonpolar lamp production. This is no polar lights for the first time from the laboratory to the marketplace, is no pole lamp "single spark". Who would have thought, this spark Liaoyuanzhishi, is ten years later.

    In 2003, Shanghai Hongyuan Lighting Electrical Appliance Co., Ltd. to large-scale IC integrated circuit techniques are applied to the light source manufacturing, succeeded in inventing the LVD low-frequency electrodeless lamp. Followed by the Shanghai Hongyuan active LVD low frequency electrodeless lamp market, began the process of water market.

    In 2005, the electronic information technology and System Research Institute of Zhejiang University, with the development of the radio frequency technology of the enterprise, the cost of the development of the radio frequency technology, so that the cost of the pole lamp is greatly reduced. This is an attempt to reform the technology of the endless lamp, and in the market to continue to verify. Because of Yuan Guangde, sdanda enterprises again and again on the market of the enlightenment, again and again for no pole lamp to drum up support promotion, only the electrodeless lamp has gradually become Liaoyuanzhishi today.

    After 2007, with Zhengxin group, Shun Cheung company has entered the area of non polar lights, no pole lamp market promotion, brand promotion has become the trend of the times, electrodeless lamp as light source market to be reckoned with.

    Nowadays, there are two major schools in the development of the non polar lamp manufacturing enterprises, which are divided into schools: the low frequency and the high frequency and the high frequency. Shanghai Hongyuan lighting, Jiangsu Zhengxin group are low frequency electrodeless lamp school representatives, and Hebei gem group, Shenzhen gelinlai lighting are high-frequency electrodeless lamp and outstanding enterprises. The high frequency and low frequency lamp adopts the built-in magnetic field induction principle, while the low frequency and the low frequency lamp adopt the principle of external magnetic field induction. The main difference between the two is the heat radiation and the magnetic field frequency is different.

    There was no significant difference between the pole lamp and LED
