LED design appeared to break the design methods and ideas of traditional light sources, there are three new design. 1. Scenario Lighting: 2008 presented by Philips scene lighting, demand environment to design lamps. Scene lighting in place as a starting point, intended to create a beautiful, brilliant light environment, to heighten the effect of the scene, people feel there is a scene atmosphere. 2. mood lighting: 2009 proposed by the COSIO mood lighting, people's needs to design lamps. Mood lighting is human emotion as the starting point, from a human point of view to create a mood like light conditions. Mood lighting and scene lighting is different, mood lighting is dynamic, lighting the way to meet people's spiritual needs, people feel a mood; and scene lighting is static LED lighting mirror, it only emphasizes the needs of the scene illumination, And people can not express emotions, a sense LED lighting, mood lighting scene lighting cover. Mood lighting includes four aspects: First, green energy, the second is healthy, the third is intelligent, four is humane. LED lighting LED lighting principle is Ⅲ-Ⅳ compounds, such as GaAs (gallium arsenide), GaP (Gallium Phosphide), GaAsP (gallium arsenide phosphorus) and other semiconductor made of LED lighting manufacturers, and its core is the PN junction . IN feature so that it has a general PN junction that is forward, reverse blocking, breakdown characteristics. In addition, under certain conditions, it also has luminescent properties. In the forward voltage, electrons from the N zone injection P area, hole injection from the P District N District. Into other areas of minority carriers (minority) part of the majority carriers (many children) composite and light. Assume emitting occurred in the P region, the injected electrons and valence band holes direct composite and light, or light-emitting center was first captured, then with the hole recombination. In addition to this light-emitting compound, some electrons are (between the center of the conduction band, dielectric belt near the middle) non-luminescent center to capture, and then with the hole recombination, each time the energy released is not, can not form visible. Emitting composite volume relative to non-emitting composite volume ratio greater LED lighting Guinness, higher quantum efficiency. Since the compound is in the minority carrier diffusion area glowing, so light produces only near PN junction within several μm. Theory and Practice shows that the peak wavelength λ of the light band gap semiconductor material emitting region Eg about that λ≈1240 / Eg (mm) where Eg units of electron volts (eV). If you can produce visible light (wavelength of 380nm violet ~ 780nm red), Eg of semiconductor materials should be between 3.26 ~ 1.63eV. Longer wavelength than the red light to infrared light. Now there are infrared, red, yellow, green and blue light-emitting diodes, but blue-light LED cost, the price is high, use not common.
