LED DRIVER, LIGHTING SYSTEM AND DRIVING METHOD WITH PROLONGED LIFETIME OF LUMINOUS OUTPUT. |
| 摘要 |
An LED driver implements a first constant-current drive scheme for a first range of sensed voltages up to a threshold voltage. After this, a second drive scheme is implemented with a current lower than the constant current of the first drive scheme. |
