What is the difference between the power LED and high bright Normal LED ?
High bright normal LEDs are made from single chip while the power LEDs are made from multiple diodes in a single chip. The diodes are arranged in series and parallel, at the time of doping. The chip manufacturing of the single chip is always more economical, than an Integrated chip. Higher efficacies are achievable in single chip, compared to multi-diode LED. This is because of the fact that when a single LED is not performing, it can be segregated and rejected, while in a multi-diode, the average LED performance is taken. Thus, for the same basic technology, the multi diode LED has marginally less efficacy than the the single chip LED. In power LED higher heat dissipation takes place in a smaller area, compared to the total area available in a single chip LED. Thus, power LED always requires heat sink, while single chip LEDs normally do not require heat sink. The power LEDs have diodes in series and parallel internally, thus requiring higher voltage.
