  • Publication number: 20150111319
    Abstract: Disclosed are a method and system for eliminating yellow ring phenomenon occurring on the white light emitting diode (LED) based on a blue light chip exciting yellow phosphor powders and having a packaging surface enclosing thereon. Lightspot images are repeatedly acquired outside the white LED, and then each analyzed to see if the yellow ring still exists on a lightspot. If yes, a further atomization process is performed on the packaging surface of white LED, until the acquired and analyzed image shows no yellow ring exists. A lightspot-by-lightspot basis is used in the yellow ring elimination task. In the image analysis, a look up table may be provided in advanced or established at the same time simultaneously with the yellow ring elimination task. The atomization performed on the lightspot may also consider a width issue.
