ABSTRACT:
A flash module has a first light-emitting diode (“LED”) optically coupled to a first lens having a first viewing angle, and a second LED optically coupled to a second lens having a second viewing angle. The second viewing angle is greater than the first viewing angle. A first control signal line coupled to the first LED allows selectively activating the first LED. A second control signal line coupled to the second LED activates the second LED.
