摘要： A lighting system is described. One embodiment of the lighting system includes a light guide, a first lighting device, and a second lighting device. The light guide receives light along a transmission interface. The first lighting device has a first plurality of lighting elements coupled to a first substrate between a first pair of reflector walls. The first substrate and the first pair of reflector walls define a first exposed side of the first lighting device. The second lighting device has a second plurality of lighting elements coupled to a second substrate between a second pair of reflector walls. The second substrate and the second pair of reflector walls define a second exposed side of the second lighting device configured to match the first exposed side of the first lighting device. Using lighting devices without sidewalls illuminates a diffusion panel so that there are no dark spots.

摘要： A control circuit having a drive circuit and a controller adapted for use in optical mice is disclosed. The drive circuit is connected between first and second ports and passes a current between those ports having an amplitude determined by a control signal that is generated by the controller. The first port is connected to an illumination device and the second port is connected to a power rail. The control circuit also includes a potential measuring circuit that generates a signal indicative of a drive circuit potential between the first and second ports. The controller records the drive circuit potential for a predetermined current when the first port is connected to an illumination device. The controller sets the control signal based on the recorded drive circuit potential. The control circuit can record the drive circuit potential when the controller is powered.
