An array of reflectors is arranged to approximately match the arrangement of a two-dimensional array of LEDs such as used in a 2-D bar code scanner. Each reflector has at least one reflecting wall for reflecting light from a respective LED, thus increasing the amount of LED light illuminating the target.

[ We claim:] [1.] A light director for use with non-contact bar code symbol readers of the type including a two-dimensional array of light sources for illuminating a two-dimensional field of view, comprising:a director body member including a two-dimensional array of light directing units, each of which directs light generated by a respective one of said light sources toward said two-dimensional field of view as a whole, each of said light directing units including:(i) a first open end for receiving light generated by a corresponding light source located in proximity thereto;(ii) a second open end through which light received into the corresponding first open end is able to pass out of said director; and(iii) a wall extending between said first and second open ends for increasing the fraction of light passing out of said second open end, wherein light passing from said second open end of each of said light directing units impinges in an overlapping manner onto said field of view as a whole, said illuminated field of view extending a predetermined distance from said light director.
