| titleOfInvention | A tunable white light source |
| abstract | A tunable white light source (1), comprising: at least one first light emitting diode (2) adapted to emit light of a first integrated color point; at least one second light emitting diode (3) adapted to emit light of a second integrated color point different from said first integrated color point, wherein said first and second integrated color points are selected such that the combined light output of the first and second light emitting diodes appears white in color; and a control unit (5) for tuning a color temperature of white light output by said tunable white light source by adjusting the relative light output between said at least one first light emitting diode (2) and said at least one second light emitting diode (3), wherein the control unit (5) is configured to restrict the color temperature of the white light output by the tunable white light source (1) to a tunable color temperature range (8) where both the at least one first light emitting diode (2) and the at least one second light emitting diode (3) emit light for all color temperatures in the tunable color temperature range. |
