| Abstract: | To study illumination of power-LED,different batches of blue and white power-LEDS were tested.We tested the relative intensity,luminous flux and luminous efficacy change with current,and observed the relationship of light wavelength and current.Meanwhile,we tested luminous flux,luminous efficacy and color coordinates.There is a preliminary study in this paper,the results will provide a reference to the lighting of power-LED and for the further study. |
