Embodiment Construction
[0010] figure 1 A perspective view illustrating an optical system 100 that may be used with a compact light source, such as a light emitting diode (LED) 102 , in accordance with one embodiment of the present invention. It can be seen that the optical system 100 has a narrow aspect ratio, for example 3:1, but this can be changed as desired. figure 2 and 3 are respectively along the major axis 101 of the optical system 100 long and minor axis 101 short side view. Long axis 101 long and minor axis 101 short orthogonal to each other. The optical system 100 causes the light emitted from the light source to be distributed substantially uniformly throughout the exit window 106 of the optical system 100 and to be strictly collimated, ie directed in a direction substantially perpendicular to the plane of the exit window 106 . It is widely understood in the art that collimated light is not perfectly collimated, but may have some degree of angular spread.
