  • Publication number: 20110203522
    Abstract: A system and method for depositing a phosphor composition onto a light emitting device improves manufacturing yield, simplifies conventional processes, and decreases costs. For example, a method of dispensing a phosphor composition onto a light emitting device includes dispensing a portion of the phosphor composition onto the light emitting device utilizing a plurality of colored phosphor dispensers each for dispensing a respective type of phosphor. Power is applied to the light emitting device to emit light, and a characteristic the light emitted by the light emitting device is detected. Phosphor mixing and phosphor dispensing are dynamically controlled. Therefore the color characteristics of phosphor dispensed on LEDs are consistent. The system and method may also reduce the difference between detected characteristic of the light and a desired characteristic of the light.
