a second light bending device surrounding at least a portion of the first light bending device, wherein the second light bending device receives the directed light rays from the first light bending device and direct the light rays in a second desired lighting pattern.
2. The lighting system according to claim 1 , wherein the second light bending device is a light pipe.
3. The lighting system according to claim 1 , wherein the second light bending device is a reflector.
4. The lighting system according to claim 1 , wherein the second light bending device is a light pipe having a substantially triangular cross-section.
5. A lighting system comprising:
a light source;
a first light bending device disposed adjacent the light source and receiving a substantial portion of light rays emitted therefrom, wherein the first light bending device includes a first portion and a second portion, the first portion having a substantially circular disk shape with an indentation formed therein for internally reflecting light in a substantially radially outward direction and the second portion disposed between the first portion and the light source, the second portion is a refractive lens having a generally dome shape with a curved first side and a second side having a cavity formed therein and disposed adjacent the light source to receive light emitted from the light source, whereby a curvature and a shape of the first side and the second side cooperate to provide a desirable refraction pattern in a substantially radially outward direction; and
a light pipe spaced from the first light bending device and surrounding at least a portion of the first light bending device, wherein the light pipe receives the directed light rays from the first light bending device and direct the light rays in a second desired lighting pattern.
6. The lighting system according to claim 5 , wherein the first light bending device substantially collimates the light rays emitted from the light source in a radially outward direction.
7. The lighting system according to claim 6 , wherein the light pipe receives the collimated light rays emitted from the first light bending device substantially uniformly across the light pipe.
8. The lighting system according to claim 5 , wherein the first light bending device focuses the light rays emitted from the light source in a substantially radially outward direction.
9. The lighting system according to claim 8 , wherein the light pipe receives the focused light rays emitted from the first light bending device substantially uniformly across the light pipe.
10. The lighting system according to claim 5 , wherein the light pipe has a substantially triangular cross-section.
11. The lighting system according to claim 5 , wherein at least a portion of the light emitted from the light source pass through the second portion of the first light bending device prior to passing through the first portion of the first light bending device.
12. A method for providing a lighting pattern, the method comprising the steps of:
providing a first light bending device disposed adjacent a light source and receiving a substantial portion of light rays emitted therefrom, wherein the first light bending device includes a first portion and a second portion, the first portion having a substantially circular disk shape with an indentation formed therein for internally reflecting light in a substantially radially outward direction and the second portion disposed between the first portion and the light source, the second portion is a refractive lens having a generally dome shape with a curved first side and a second side having a cavity formed therein, whereby a curvature and a shape of the first side and the second side cooperate to provide a desirable refraction pattern in a substantially radially outward direction;
spacing a second light bending device from the first light bending device, the second light bending device surrounding at least a portion of the first light bending device, wherein the second light bending device is receives the directed light rays from the first light bending device; and
directing at least a portion of the light rays emitted from the light source through the first light bending device and then the second light bending device to provide a second desired lighting pattern.
13. The method according to claim 12 , wherein the second light bending device is one of a reflector and a light pipe.
14. The method according to claim 12 , wherein the first light bending device includes a first portion and a second portion, the first portion having a substantially disk-like shape with a substantially parabolic indentation for reflecting light rays and the second portion adapted to refract light rays.
