Optical waveguide

An optical waveguide for use in converting the distribution pattern of light from an LED source, the optical waveguide comprising:

• a guide having at least two ends;
• a collection optic positioned at one end of the guide for channeling light from said LED source into said guide;
• a distribution optic positioned at a second end of the guide for receiving the light channeled through the guide by the collection optic,
• said distribution optic including at least a first optical surface and a second optical surface, wherein at least a portion of said first optical surface is reflective so as to reflect at least a portion of the light channeled through the guide to the second optical surface, which distributes the light in a rotationally symmetric distribution pattern.

A method for transforming the distribution pattern of light from an LED source, said method comprising the steps of:

• collecting light from the LED source through a collection optic into a guide;
• channeling the light through the guide to a distribution optic, said distribution optic including at least a first optical surface and a second optical surface, wherein at least a portion of said first optical surface is reflective;
• reflecting at least a portion of the channeled light off of the first optical surface toward the second optical surface;
• emitting a light distribution pattern from said second optical surface of the distribution optic which is distinct from the distribution pattern of the LED source.

An optical system for transforming the light distributed from a limited output source, said optical system comprising:

• a light source;
• a primary optic coupled to the light source, said primary optic including
• a collection optic positioned proximate to the light source for channeling light from said light source;
• a distribution optic oriented to receive the channeled light from said collection optic, said distribution optic outputting the channeled light into a distribution pattern distinct from that emitted from the light source;
• a secondary optic coupled to the primary optic, said secondary optic including at least one optical surface for transmitting the light emitted from the primary optic through the secondary optic to a surrounding environment.

A warning light for use in combination with a warning barricade device, said warning light comprising:

• a light source coupled to a power source;
• a primary optic positioned proximate to the light source, said primary optic including
• a collection optic for channeling light from said light source;
• a distribution optic oriented to receive the channeled light from said collection optic, said distribution optic including at least a first optical surface and a second optical surface, wherein at least a portion of said first optical surface is reflective SO as to reflect at least a portion of the light channeled through the guide to the second optical surface, which emits a distribution pattern distinct from the distribution pattern of the LED source;
• and
• a secondary optic coupled to the primary optic, said secondary optic including at least one optical surface for transmitting the light emitted from the primary optic through the secondary optic to the surrounding environment to render the warning light visible for use.

A warning barricade apparatus for restricting vehicular and pedestrian access to a particular area, said warning barricade apparatus comprising:

• a barricade member;
• a warning light associated with said barricade member;
• said warning light including a light source coupled to a power source;
• a primary optic positioned proximate to the light source, said primary optic including
• a collection optic for channeling light from said light source;
• a distribution optic oriented to receive the channeled light from said collection optic, said distribution optic including at least a first optical surface and a second optical surface, wherein at least a portion of said first optical surface is reflective so as to reflect at least a portion of the light channeled through the guide to the second optical surface, which emits a distribution pattern distinct from the distribution pattern of the LED source;
• and
• a secondary optic coupled to the primary optic, said secondary optic including at least one optical surface for transmitting the light emitted from the primary optic through the secondary optic to the surrounding environment to render the warning light visible for use.
