reflection conditions within the led housing a second reflection surface of the reflector may be aligned with the increased exit angle of the total internal reflection light component because the angle is higher than that of light escaping sideways from the led housing the second reflector surface appears as a step back in the first reflection surface and does not degrade the first surface 39 s ability to redirect the sideways escaping light component the extra materials cost of the reflector 23 is recouped be the lowered number of leds 8 required and the lower operating costs due to reduced energy consumption the reflector s may be configured around individual leds or clusters of leds a channel shaped reflector 23 allows a limited cross over of the light emitted between nearby leds lessening the change to the display aspect if one or more of the individual leds fails the size of the pcb 5 may be determined by the smallest circle rectangle or other shape that will encompass the desired led pattern thus saving material costs by minimizing the size of the pcb 5 where arrow symbols are being displayed the arrow form may be cut from a bulk pcb panel 22 cut out as shown in fig6.
