| Abstract: | Combined with its excellent performance and intelligent control system,LED is increasingly used in indoor and outdoor lighting situations,however,correlated color temperature(CCT),color rendering index(CRI)are required.To meet this challenge,a novel color temperature tunable(CTT)LED is presented,high-power LED chips and metal substrate are used to package CTT LED with warm white and high CRI,luminescent spectrum,CCT and CRI are measured with the changing of current,it is shown that there are there peaks,the... |
