20130069522 | WAY OF REDUCING LED'S COLOR TEMPERATURE AND COLOR COORDINATES DRIFTING - The present invention relates to a way of reducing LED's color temperature and color coordinates drifting, more particularly to a phosphor-converted LED with blue ray light emitting body so that the influence of LED's heat dissipation on color performance can be minimized. | 03-21-2013 |
20130257265 | PHOSPHOR-CONVERTED WHITE LED WITH LOW DEVIATION OF CORRELATED COLOR TEMPERATURE AND COLOR COORDINATES AND METHOD OF PREPARING THE SAME - A light emitting device is provided to produce white light with a stable correlated color temperature and stable color coordinates. The light emitting device includes a blue LED chip and a yellow phosphor. The blue LED chip has a peak wavelength X slightly smaller than the peak wavelength Y of the phosphor such that when the light emitting device is subjected to a predetermined operating current, the phosphor decays due to thermal effect, and the LED chip has its emission spectrum red-shifted to substantially match with the excitation spectrum of the phosphor. At this time, the excitation ability of the LED chip is increased and causes an increase of yellow power output from the phosphor that substantially compensates a decrease of yellow light output caused by the phosphor. | 10-03-2013 |
