LED lighting revolution, semiconductor lamp life 50 years

In the United States 100 years ago, Edison invented the incandescent light bulb, lead humanity into the new era of lighting; now Chinese in Nanjing, a returning doctor is full of passion, to promote the industrial application of domestic semiconductor lighting, general manager of the Nanjing Henderson Semiconductor Lighting Co., Ltd Liang Bingwen.

Liang Bingwen, Henderson semiconductor lighting technology research to chip and industrial applications, the goal is to make the first brand China semiconductor lighting".

Committed to the development of energy-efficient lighting, a lamp with a lifetime

Liang Bingwen's desk with two lamps, from the appearance is not what special, two times but the two lamp stands for lighting technology, one is relying on the electric incandescent lamp heating wire light, the other is a semiconductor lamp manufacturing henderson. Semiconductor lamp uses efficient LED (semiconductor light-emitting diode) as a new light source, there is no traditional lamp bulb, the light of the "organ" is the semiconductor chip, the electronic directly into the photon. Under the same brightness, the power consumption of the semiconductor lamp is only 1/10 of the ordinary incandescent lamp, but the life span has been extended by more than 100 times. Liang Bingwen said that such a lamp can be used for 50 years, almost a lifetime.

Located in Jiangning Henderson Science Park opened in 2002, a total investment of 120 million yuan, specializes in high power semiconductor lighting technology and application of downstream products R & D, production and sales of high-tech fields into a broad market prospects, leading the development of the domestic semiconductor lighting technology. This research goal is the development of Henderson semiconductor lighting company, 3W 3W and above power products, to build a new production line, its production efficiency and automation level has reached the international advanced level.

A number of patents in hand, the lamp can be made into ceiling

In 1993 his PhD degree in electrical engineering in the United States Liang Bingwen, after returning home in 2004 to become group leader of the national semiconductor lighting industry technology development strategy research experts, responsible for the development of semiconductor lighting industry in the national long-term technology development plan.

Liang Bingwen currently holds 5 US patents, 11 patents Chinese, under his auspices, Nanjing Henderson last year applied for 16 patents, these patents are currently in the domestic leading position, research and some even ahead of their American counterparts. One dimensional semiconductor light source light source technology, can be done in a flat sheet, this "flat light" is not used in the grille on the ceiling, the ceiling directly and as a whole, the future can even have different colors, the user can adjust the color according to the mood.

It is reported that the current domestic semiconductor lighting products are imported from abroad, such as a 1W lamp, the import price of about $5, while mastering the patented technology, domestic prices will be reduced by at least half.

Semiconductor lighting is expected to enter the family, the main market in the future abroad

According to estimates, assuming that only 1/3 of the incandescent lamp replaced by semiconductor light, every year will be able to save nearly 100 billion of electricity, equivalent to a generating capacity of the Three Gorges Project; if by 2025 half of the ordinary light source was replaced by semiconductor lighting, it means the world every years will save electricity and reduce the $100 billion, 3.5 million tons of carbon dioxide emissions.

City lighting is the largest market for domestic semiconductor lighting at Jiangning stadium is used to Henderson semiconductor lamp, Liang Bingwen said, two or three years later, energy saving and environmental protection of the semiconductor lamp will be entered into the ordinary family.

Liang Bingwen said that Henderson semiconductor lighting annual sales revenue of 8% - 10% for research and development, grasp the autonomous technology, its development perspective is already on the international market, to become the first brand of domestic lighting at the same time, there will be 80% - 90% of the products to enter the international market.
