1. high power LED downlight definition

High power LED downlight is the high-power LED lighting as a light, it belongs to a type of directional lighting, embedded and non-embedded forms, compared with ordinary lamps, its light is focused, relatively strong chiaroscuro.

High power LED tube lamp above 80%, life expectancy is more than 10 times of ordinary lamps, is virtually maintenance-free, must be frequently replaced is not an issue, about half down costs can in Exchange for cost savings. Green semiconductor light source, light, soft, spectrally pure, eye protection and health in favour of people, cool on the cold light source giving the Visual feel, helps to focus and improve efficiency.

2. high power LED lamp light works:

Fixed voltage of PN junction constitutes a barrier, when Jiazheng times base bias voltage drop the p-and n-proliferation of majority carriers toward each other. Because the electron mobility is much larger than the hole mobility, so there will be a large number of electrons from p diffusion, constitute p areas of minority-carrier injection. These electrons and the valence band holes of composite, compound the energy released as light. This is the high power LED downlight PN junction light principle.
