A light source apparatus

A light source apparatus for providing an adjustable number of wavelength channels, the light source apparatus comprising:

• at least a first plurality of LED modules, each LED module comprising an LED, a housing which at least partially encloses the LED, and a light director attachable to said housing for directing light emitted by the LED;
• the first plurality of LED modules being attached to a support structure in a first arrangement via attachment means;
• wherein, in the first arrangement, light emitted by each LED of the first plurality of LEDs is directed along a first optical axis;
• and
• the light source apparatus further comprising a plurality of driver PCBs and a controller PCB, each driver PCB of the plurality of driver PCBs being coupled to the controller PCB, and each LED module of the first plurality of LED modules being coupled to a first driver PCB of the plurality of driver PCBs;
• wherein the controller PCB is configured to provide control signals to each of the driver PCBs, and wherein each driver PCB is configured to provide drive signals to any LED module coupled with it.

A method of manufacturing a light source apparatus, the method comprising:

• providing at least a first plurality of LED modules, each respective LED module comprising a housing enclosing an LED and a light director attachable to said housing for directing light emitted by the LED;
• attaching the first plurality of LED modules to a support structure in a first arrangement via attachment means such that light emitted by each LED is directed along a first optical axis;
• and
• the method further comprising providing a plurality of driver PCBs including a first driver PCB, each driver PCB being configured to provide drive signals to LED modules coupled thereto;
• coupling each LED module of the first plurality of LED modules to the first driver PCB;
• and
• coupling each driver PCB of the plurality of driver PCBs to a controller PCB, the controller PCB being configured to provide control signals to each of the driver PCBs to control the drive signals sent to each LED module.
