白光發光二極體結構及其製造方法

The present invention provides a white light LED structure and manufacturing method thereof, providing a substrate, provided thereon with a plurality of LED chips, spraying the phosphor powder onto the LED chips, and LED chip is, using a temporary adhesive, adhered to the temporary substrate. The substrate bottom is polished, and a plurality of indentation grooves is cut out on the substrate bottom, and the substrate is formed thereon with the reflective layer. Subsequently, after the temporary adhesive and the temporary substrate are removed, the LED chip is separated to form a substrate provided with an inclined surface each on both sides. The substrate's outer layer is plated with a reflective layer, and the substrate is provided with an LED chip with spraying phosphor. The present invention can make the light reflection homogenized, and excite the LED chip's phosphor to let the white light LED uniformly shine the white light.
