| 摘要 |
The present invention proposes an LED dimming module (10) comprising two LED strings (1,2), the first LED string (1) comprising at least one color converted blue or UV LED (1a) and the second LED string (2) comprising at least one amber light emitting LED (2a), the LED module further comprising control means (3) connected to the first and second LED string (1,2), said control means (3) being designed to selectively vary a current provided to the first LED string (1) such that a non-linear dimming curve (13b) of the resulting emitted light is obtained, said dimming curve (13b) approaching the planckian curve (9) on the CIE chromaticity diagram. |
