Subject: Automotive LED-use a transparent GaP substrate material
2010-01-22




Over the past AlGaInP the LED, the substrate materials used for the GaAs, ran a black surface of the pn junction GaAs so that half of the light emitted was blocked absorbed, resulting in a waste of light, so do use a transparent GaP substrate material. Another example is Japan's Nichia Chemical Industries (Nichia) in GaN The LED in the p-type electrode (p type) made part of the reticulate-like (Mesh Pattern), in order to increase the transparency of the p pole to reduce obstacles and increase the optical light flux.
