Abstract
The present invention provides a method, system and structure for maintaining light characteristics from a multi-chip LED package. This may be done by selecting a desired light output and restricting light from a plurality of light emitting diodes in the multi-chip LED package. It may also be done by measuring the restricted light, comparing the measured output light to the desired light and by adjusting current to LEDs in the multi-chip LED package based on the measured light.
