| Title: |
Light Source |
| Abstract: |
The invention concerns a light source utilizing an array (20, 50) of light
emitting elements (22). The elements may be light emitting diodes. A
fresnel prism (32, 56) is disposed in front of the array to receive light
from it. The prism serves to divert light from the array along a
direction (28, 54) oblique to the array, the diverted light forming an
output beam. The array has a depth. The output beam from the prism has a
depth which, measured in the same plane as the array depth but
perpendicular to the beam direction, is smaller than the depth of the
array. Hence a deep array provides a shallower output light beam in a
manner which is convenient with regard to packaging requirements.
