INTRODUCTION:- A diode which are given light when it is forward bias is called LED. Led is the abbreviation of light emitting diode. Silicon or germanium are not used to made led. The other elements like as gallium and arsenic are used to made this type of diode. To produce different lights like as red, blue, green or yellow with different wavelengths, it is possible to varying the quantities of these elements which are used to made this type of diode. For example red light diode are manufactured by using gallium arsenide. Same as this method gallium phosphide are used to manufactured green colour led. ……
