According to the latest research results of Mr. Qian Zongming, China conceived LEDs in the Eastern Jin Dynasty. There is such a description in the collection of the mysterious novels of Wang Jia in the Eastern Jin Dynasty:
The first emperor was a good god, and there were people of Wanqu, who came by the boat. The boat is shaped like a snail, sinking under the sea, and the water is not immersed, a "chopper boat." The country’s people are ten feet long, and the hair of the birds and beasts is shaped. The first emperor and the language, and the beginning of the heavens and the earth, as a relative.曰 “ “ “ “ “ “ “ “ 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣 臣On a sunny day, the sky suddenly bursts, and if it is Jiang Han. There is a black dragon in the black dragon, slamming down. And the night, burning stone in the sun. This stone is burning the mountain, its earth and stone are all from the light, buckle Then it is broken, like a millet, and a grain of radiance is reflected. The dynasty dynasty began to change into raw food, and this fire is also used. The Chinese people present this stone. Or they cast their stones in the stream, then the boiling water flows in dozens of miles, the name of the water For Jiao Yuan.
The “Wanqu Country†mentioned above not only has the “chopper boat†like the current submarine, but also the “Ranshan Stone†with the shape of the grain. This kind of illuminant with only the grain size can be used only one grain. If you are thrown into the river, you will "boiling in a few dozen miles."
Mr. Qian Zongming explained that the illuminant of the Eastern Jin Dynasty Wang Jia was as large as a rice grain, a illuminating one, and boiling in the water, just like today's lighting source LED, and its technology even surpasses modern technology, maybe it No power supply, no need to drive, no heat dissipation system, and its light efficiency is even higher than our modern high-power chips.
The surreal scientific fantasy of the ancients really admired us. However, we Chinese have indeed discovered an LED - OLED. "The father of OLED" Deng Qingyun was born in Hong Kong. He worked as a research scientist at the Kodak Lab in Rochester, New York, and discovered OLED in 1979. In 2011, Deng Qingyun and the two colleagues jointly won the Wolff Chemistry Prize, which is the international award after the Nobel Prize in the field of chemistry.
The superiority of LED as a new light source has been recognized by most people. However, recently, in Europe, LEDs have been resisted by traditional light sources.
Continue RoHS waiver
On October 29th, the European lighting industry sent a written request to the European Commission to approve the continued RoHS (European Union directive on the restriction of the use of hazardous substances in electrical and electronic equipment) for fluorescent and high-intensity discharge (HID) lighting equipment categories. Exemption. The exemption consists of 29 products covering products containing mercury, lead, copper alloys, cadmium and hexavalent chromium.
The consultation on the request has ended on October 16 and it is expected that the European Commission will make a decision by the end of 2016.
At the same time, environmental NGOs are emphasizing the committee's disregard for industry demand and urging it to limit sales of compact fluorescent lamps (CFLs). “CFLs can be replaced by safer and more energy-efficient mercury-free light-emitting diode (LED) lamps,†said Elena Lymberidi-Settimo, manager of the Zero Mercury Project at the European Environment Agency (EEB). For other lighting categories, NGOs want to implement lower mercury limits within two years of the current RoHS directive.
Delayed implementation of halogen bulb ban for two years
Regulation No. 2015/1428 of the European Commission (EC) will be implemented in the EU countries on February 27, 2016 to amend the environmental design rules applicable to lighting products (including household bulbs). After reviewing Regulation No. 244/2009, the Commission found that the “Sixth Phase†restriction on Schedule 1 of Regulation No. 244/2009 (ie the maximum rated power for a given luminous flux), the manufacturer is required to It is not economically feasible to develop and deliver luminaires that meet the restrictions from September 1st. In fact, after the European Commission has estimated that the lighting technology with better energy efficiency is expected to develop, it is considered that the above-mentioned limitation is better implemented on September 1, 2018.
As early as April 17, 2015, the EU Environmental Design Regulatory Commission passed a resolution with only a few micro-vouchers to postpone the phase-out of halogen bulbs from 2016 to 2018, due to the strong lobbying of the lighting industry to the European Commission and EU member states indicate that LED technology is not yet ready. It is generally believed that once halogen lamps are completely eliminated, LED technology will be replaced.
Fluorescent lamp tube sockets are not compatible led
In the European and American markets, the retention rate of fluorescent sockets is quite high, which is very large because the specifications of fluorescent sockets are quite different. If consumers want to replace the original fluorescent tube with an LED tube, it is often difficult to determine which LED tube should be used, and replacing the fluorescent socket together greatly increases the replacement cost. The problems of service life and safety caused by incompatible LED lamp replacement have become the main obstacles for LED replacement of fluorescent lamps.
The OneTLed technology just acquired by Op Lighting is expected to solve the above compatibility problems. On October 28th, Op Lighting signed a technical cooperation agreement with Seaborough, based in Amsterdam. The signing of this agreement marks the first step in the official launch of the world's first universal LED tube, oneTLed.
Developed by Seaborough and the world's leading scientists, OneTLed technology is a combination of hardware and software that can be incorporated into any LED tube. OneTLed is compatible with all types of ballasts and is inexpensive. A LED lamp can be safely loaded oneTLed art ballasts use energy savings led lamp tube socket TL any transformation. This groundbreaking result has always been expected by the market.
Currently, there are an estimated 12 billion sockets worldwide, and the sustainable energy-saving LED tubes with oneTLed technology will save half of the electricity, which will accelerate the energy saving process. If the LED tube replaces all the fluorescent tubes, the energy saved is equivalent to the power generated by more than 100 medium-sized power plants. In addition, oneTLed is very environmentally friendly, free of mercury or any other toxic chemicals. With an average service life of more than 8 years, oneTLed will also significantly reduce costs and reduce wastewater discharge.
European traditional lighting for LED's resistance and attempt to "restore", we can not help but surprise. It seems that the industrialization of LED still has a long way.
