Abstract
A white multi-wavelength LED and its manufacturing process has bonded at the bottom of a light emitting chip in a given color a first non-conductive material containing phosphor in a corresponding color to that of the chip to become a die unit; the first non-conductive material functioning as the position where the die unit is bonded to a carrier; golden plated wire constituting the circuit connection of the chip; a second non-conductive material containing phosphor in a color corresponding to that of the chip being injected to cover up the top of the chip to emit the expected white light and effectively promote the luminance performance of the LED.

A white multi-wavelength LED manufacturing process includes the following steps.
- a. Prepare a light emitting chip in a given color;
- b. A die unit is prepared by having a first non-conductive material containing phosphor in a color corresponding to that of the light emitting chip bonded to the bottom of the light emitting chip;
- c. Bond the die unit to a carrier with an encapsulating material;
- d. Inject a second non-conductive material containing phosphor in a color corresponding to that of the light emitting chip into the carrier to cover up the light emitting chip;
- e. Finish with the baking process.
