摘要： An LED CoB structure with the combination use of blue and red LED dies is used to achieve warm white light, with good quantum conversion efficiency at a reasonably low cost. Both the red and blue LED dies are fabricated on transparent substrates. The current density of the LED dies is designed to match the different degradation rate of each type of LED die. The methods used to achieve high efficiency include adjusting the power, wavelength, and/or position of the dies.
