Method of power and temperature control for high brightness light emitting diodes |
| 摘要 |
Various embodiments relate to a method for driving a light emitting diode (LED) flash including: measuring a junction temperature of the LED by applying a test current to the LED and measuring the LED forward voltage; determining the drive current based upon the measured junction temperature and measured data characteristics of the LED; and applying the drive current to the LED for a specified length of time. |
