Abstract

一种色温可调的白光发光二极管,它包括有至少一个功率型发光二极管芯片和与它相配置的发光材料,至少一个有色可见光发光二极管芯片;发光二极管芯片的电极经电连接线与用于和外电源相连的电连结器相连,发光二极管芯片为可调节发光强度的发光二极管芯片,它们被用高热导率胶固定在一个高热导率的金属底座上;它具有出射光的光色、色温和显色指数可调、出射光的颜色随工作时间增加而发生的色漂移可补正、也可用于制造高显色指数的白光发光二极管等优点。可替代现有白光发光二极管,用于显示、照明和液晶显示背照明等。
The utility model discloses a color temperature adjustable white-light LED, including at least one power type LED chip, luminescent materials matched with the power type LED chip and at least one color visible LED chip. The electrode of the LED chip is connected with an electric connector used for connecting with an external power supply through an electric connecting line, and the LED chip is an LED chip with adjustable luminous intensity. These components are fixed on a high heat conductivity metallic socket through high heat conductivity glue. The utility model has the advantages of that the light color, the color temperature and the color rendering index of the emergent light are adjustable, the color dispersion of the emergent light following the increased operating time can be repaired and the color temperature adjustable white-light LED can be used for manufacturing the white light LED with high color rendering index, etc. The existing white light LED can be replaced, and the color temperature adjustable white-light LED can be used for displaying, lighting and back lighting of liquid crystal display, etc.
