LED tube light is application of a new type of LED lighting light source on the basis of traditional tube light of the development of improved products, compared with traditional tube light has the following advantages: energy saving, low carbon, long life, good color rendering and fast response.LED tube light, a design more beautiful light, installation to keep building decoration of the overall unity and perfect, does not destroy the set of lamps and lanterns, light hidden inside the building decoration, light source is not exposed, no glare, the visual effect of soft and uniform.
P-n junction terminal voltage constitute a certain potential barrier, when the positive bias voltage drop time base, P and N the majority carrier diffusion to the other party.Due to the electron mobility is much bigger than hole mobility, so there will be a large number of electronic spreading P area, constitute of P area of minority carrier injection.These electrons and valence with hole composite, composite when the energy in the form of light energy to release out.This is the principle of PN junction glow.

Ministry of Industry and Information Technology website February 28 news, the Ministry of Industry and Information Technology, Ministry of Finance and National Standards Commission recently released the "Accelerate the development of sensors and intelligent instrumentation industry development action plan" (action plan).
According to the plan, the overall development level of the industry by 2015 should be significantly improved; the independent design, development and industrialization of a group of high-precision meters and new sensors should be completed, focusing on strategic emerging industries, industrial networking, environmental protection and food safety. , cultural heritage protection and inheritance and other fields; establish an industry common technical service platform.
In 2025, the overall level of China's sensor and intelligent instrumentation industry will enter the world's advanced ranks. The sensors and intelligent instrumentation required for national defense and key industry safety and major projects will be autonomously manufactured and autonomously controlled, with high-end products and Service market share increased to more than 50%.
The action plan pointed out that enterprises should be encouraged and supported to cultivate industry leaders with output value exceeding 1 billion yuan and “small (medium), fine, specialized, and specialized enterprises with output value exceeding 50 million yuan through means such as merger and reorganization, joint stock reform and listing, and technological transformation. Specialized and strong "innovative enterprise.
In particular, the plan proposes that enterprises that have met the relevant policy conditions may be granted relevant preferential tax policies according to regulations.
