Abstract
An LED package having an anodized insulation layer which increases heat radiation effect to prolong the lifetime LEDs and maintains high luminance and high output, and a method therefor. The LED package includes an Al substrate having a reflecting region and a light source mounted on the substrate and connected to patterned electrodes. The package also includes an anodized insulation layer formed between the patterned electrodes and the substrate and a lens covering over the light source of the substrate. The Al substrate provides superior heat radiation effect of the LED, thereby significantly increasing the lifetime and light emission efficiency of the LED.
