1. Features.
LED color and Technology
1.Different manufacturing LED materials, can produce photons with different energies in order to control the wavelength of light emitted LED, that is, spectral or color.
2.History of the first LED material is used in arsenic (As) of gallium (Ga), the PN junction forward voltage drop (VF, can be understood as light or voltage) is 1.424V, issued light for the infrared spectrum. Another commonly used material for the LED phosphorus (P) of gallium (Ga), the PN junction forward voltage drop to 2.261V, issued for the green light.
3. Based on these two materials, the early use of LED industry GaAs1-xPx materials Tu-structure, in theory, can be produced until the green light from the infrared light of any wavelength within the LED, subscript X on behalf of phosphorus to replace the percentage of arsenic. Generally through the PN junction voltage drop can determine the wavelength of LED colors. Which typically have GaAs0.6P0.
4 red LED, GaAs0.35P0.65 orange light LED, GaAs0.14P0.86 the yellow LED and so on. Because of the manufacturing using gallium, arsenic, phosphorus three elements, so-called three elements of these LED light tubes. And GaN (gallium nitride) blue LED, GaP green light LED and GaAs infrared LED, LED known as the second element. The latest process is mixed with aluminum (Al), calcium (Ca), indium (In) and nitrogen (N) the four elements the four elements of materials AlGaInN the four elements of LED, you can cover all the visible and ultraviolet part of spectral range of light. Luminous intensity:
4. Luminous intensity measurement unit illumination units (lux Lux), luminous flux unit (lumen Lumen), luminous intensity unit (Candlelight Candle power)
