The invention discloses a color-temperature-adjustable high-color-rendering
light source module, which comprises a base plate and an LED (
light emitting diode)
chip, wherein a
solid crystal region and public circuits are arranged on the base plate, and the LED
chip is fixedly arranged on the
solid crystal region and is connected with the public circuits. The high-color-rendering
light source module is characterized in that the
solid crystal region is divided into at least two integral regions, the public circuits are integral
metal plates and are in corresponding arrangement with the integral regions, the two adjacent public circuits are mutually insulated and have opposite electrodes, and the LED
chip is connected onto the two adjacent public circuits. A fluorescent
powder layer is arranged on the solid crystal region and is divided into at least one cold
color temperature high-color-rendering
light source region and at least one warm high-color-rendering light source region, according to the color addition principle, colors of two kinds or several kinds are added according to different distribution proportions, and an intermediate color is obtained. The light source
color temperature regulation is realized through regulating and controlling the current of the cold
color temperature high-color-rendering light source region and the warm high-color-rendering light source region, and the finally desired high-quality
white light after the mixing of light sources at each color temperature section is realized.
