A reproducing apparatus for reproducing data recorded on an optical record carrier is provided having an improved lifetime of the laser light source used to read the data. The reproducing apparatus includes a laser driver unit that is adapted to drive the light output of the laser light source to change from a reading mode, in which data recorded in the optical disc is being read for being reproduced, into a laser lifetime extension mode when an operation of reading said data is paused. In the laser lifetime extension mode, the laser light source is driven to emit a pulsed light output, therefore, the amount of time in which the laser light source is on without being needed is reduced and the lifetime of the laser light source is improved.

Methods and apparatus for lighting control. One or more properties of light output of one or more LEDs (124A, 124B, 124C, 124N) of an LED node (120A, 120B, 120C, 120N) of an LED-based lighting unit (110) are controlled to extend the lifetime of the LED-based lighting unit. For example, an LED node controller controlling an LED may determine whether the LED will be operated in the active light emitting state based on an LED activation probability. Thus, based on the LED activation probability the LED may at some times be in the active light emitting state and provide light output and may at other times be prevented from being in the active light emitting state and prevented from providing light output.
