Abstract
The white light emitting diodes (W-LEDs) were fabricated by using InGaN-based blue LED chip as primary light source and YAG phosphors as luminescence conversion materials. The current illumination characteristic of W-LED, the power efficiency of the integrated lighting source were studied and discussed for the practical application. Luminance performances of the W-LED lamp integrated in series were studied. The preferable applied qualifications are supplied as follows: the uniformity of the W-LED devices and the stable current supplied by drive circuit are should be guaranteed, showing that the W-LED lamp processes much lower power consumption and longer lifetime.
