LED light is mostly monochromatic – it is made up of one single colour only. Multicoloured LED lights are made by incorporating two or more different colour chips, in a single package. White light is a mixture of the three primary colours – red, green and blue, in the correct proportions. White LED lights are either of the three-chip (RGB) type, or the new high brightness devices, which use a phosphor that emits white light when illuminated by a blue or ultraviolet LED chip. LED chips are generally packaged in an epoxy bulb which acts as a lens to focus the light emitting from the chip. A narrow viewing angle LED will have a more focused beam of light and this will therefore appear brighter when looked at head on than an LED which has a wider viewing angle.
