What are led light bulbs made of?
LED is the smallest form of light source available and constructed to a diameter of around 0.25 inch. Various combinations of semiconductor material like gallium-arsenide, gallium-nitride, and indium-gallium-nitride are used to construct its solid state assembly. These materials emit light of different wavelength that makes a variety of color emission possible through LED.
The chips formed by these materials are then encapsulated in transparent or color molded plastic shells that give it the final commercial touch.
Color emitting theory of LED
What makes LED stochkholm light so popular is its availability in every possible pleasing color. You can have any color of your choice to enlighten your surroundings. Now, what's the science behind it? As we already know; color emission will be depend upon the wavelength of light emitted by LED's semiconductor material. So material and technique differ to obtain the color of choice. Some examples for you are:
White light: There are two ways to obtain a white light; either coating ultra violet chip with phosphor or by RGB (Red, Green, and Blue) system in which light from multiple LED is mixed to results in a white light. The color quality produced by white LED makes it the best alternative for traditional bulbs and CFL lights.
