Title:
DRIVE METHOD APPLIED TO LIGHT-EMITTING DIODE CHIP WITH SAME POWER BUT DIFFERENT VOLTAGE AND CURRENT SPECIFICATIONS
Document Type and Number:
WIPO Patent Application WO/2015/051590
Kind Code:
A1
Abstract:
A drive method applied to light-emitting diode chips with same power but different voltage and current specifications comprises the following steps: setting a preset power value; providing a light-emitting diode chip matching the preset power value; acquiring a working current value required by the light-emitting diode chip when the light-emitting diode chip satisfies the preset power value; inputting a drive current to the light-emitting diode chip, and enabling a current value of the drive current to maintain the working current value. In this way, the drive method can be used to drive any light-emitting diode chip with the same rate power but a different rated voltage and rated current specification.
