The world's first LED solid light bulb come out of Langfang

LED (light emitting diode) lighting energy saving and environmental protection, but the effect of single light illumination effect, become the bottleneck of traditional technology to replace the light bulb. Developed by Hebei Langfang Segotep, the world's first semiconductor photoelectric light bulb on the polyhedral solid appearance before the "2009 China (Beijing) International Lighting Fair tenth".

Light from the present, through the incandescent lamp, fluorescent lamp, semiconductor lighting, stage. The biggest disadvantage of incandescent lamps is the waste of energy, because most of its electricity will be converted into heat loss. Fluorescent lamp is a fluorescent lamp, which is more energy efficient than incandescent lamp, but it has harmful effects on the vision, and the pollution of the environment due to mercury vapor. LED (semiconductor light emitting diode) is a kind of "green light", which does not need tungsten filament and does not need a lamp tube".

Chinese academician of the Academy of Engineering Chen Lianghui considered such an account: "if the incandescent lamp is the national 1/3 semiconductor lamp replaced per year for the country save 100 billion kwh, equivalent to an annual generating capacity of the Three Gorges project. However, the current market for LED light bulbs for two-dimensional distribution, subject to the limitations of the area, become a technical problem into the homes of ordinary people.

Segotep Langfang Development Zone photoelectric company lasted 4 years, successfully developed LED polyhedral solid light bulb, light for 360 degree three-dimensional light distribution is close to the natural light. The lamp life is equivalent to 35 times the incandescent lamp, energy consumption is only 1/6, and no pollution. The new product has obtained the independent intellectual property rights and the domestic and foreign technical patent.
