Control circuitry of infrared light source for light module e.g. headlight of vehicle, has switching unit that is provided to alternately connect parallel light modules with operation apparatus

摘要

The control circuitry has an operation apparatus (101) that controls power supply to the light modules (105-107) including white LEDs (103) and infrared LEDs (104) which are provided in series arrangement. The flux voltage of the light modules is controlled such that the flux voltage corresponds with each other and a switching unit (102) is provided to alternately connect the parallel light modules with the operation apparatus. Independent claims are included for the following: (1) method for operating light module; and (2) light source.
