A method for manufacturing white light source includes the steps of providing an ultra-violet light as radiation source; and preparing two kinds of phosphors each receiving the ultra-violet light and emitting light of different wavelength. One phosphor is designated to emit light covering two wavelength regimes of three primitive colors, i.e., red light (585-640 nm), green light (500-570 nm) and blue light (430-490 nm), and another phosphor is designated to emit light covering remaining wavelength regime of the three primitive colors. The phosphors are mixed in predetermined ratio such that the lights of different wavelength are combined to provide a white light.

Provided an LED display suitable for attaching to the printed circuit board together with other surface mounted devices by surface mounting process. This LED display may sustain the high temperature of the heating oven without the warping of the reflector. The reflector of the display is made from polycyclohexylene terephalate (PCT) and this reflector is undergone a heat treatment right after the reflector is injecting molded. By this heat treatment, the molecular connections of the plastic material become more perfect. Accordingly, the reflector is inherited with excellent stability and remains this stability during the post processes and at the high temperature of the surface mounting process.
