Abstract: An LED illumination module including an LED lamp with a plurality of light emitting dies on a substrate in combination with an optic having a single focus. The light emitting dies include a single center light emitting die centered on an optical axis and peripheral dies arranged around the center die. The illumination module includes a beam forming optic having a single focus arranged over the LED lamp with the focus on the optical axis of the center die. Light emitted from the center die is substantially collimated by the optic in a focused “spot” emission pattern. Light emitted from the peripheral dies results in a more dispersed or divergent “flood” emission pattern. The center die and peripheral dies are independently controlled and the power delivered to the dies can be varied independently to generate different light emission patterns using the same optic.

Abstract: A beam forming optic for use with an LED having an optical axis. The beam forming optic includes a first light entry surface cooperating with a first light emission surface and a second light entry surface cooperating with an internal reflecting surface and a second light emission surface to redirect a portion of the light emitted by the LED divergent from the optical axis into a direction substantially parallel with the optical axis. A polygonal periphery extends from the internal reflecting surface to the second light emission surface. A void is defined by a lateral channel and a longitudinal gap extending from the second light emission surface towards the first light emission surface. A portion of the light emitted from the LED passes through the void.

Abstract: An asymmetrical optical assembly employs reflecting surfaces and a lens to combine the light from a plurality of LED lamps into an illumination pattern useful in a floodlight or work light. The reflecting surfaces and lens optical element are not symmetrical with respect to a plane bisecting the optical assembly and including the optical axes of the LED light sources. Some light from the LED light sources is redirected from its emitted trajectory into the desired illumination pattern, while a significant portion of the light from the LED light sources is permitted to exit the optical assembly without redirection. Minimizing the number of optical elements employed and the redirection of light enhances the efficiency of the resulting light assembly.

Abstract: An LED optical assembly includes an optic having first and second light entry surfaces configured to cooperate respectively with a first light emission surface and an internal reflective surface to redirect substantially all light emitted from an LED into a direction substantially parallel with the optical axis. A polygonal periphery extends from the internal reflecting surface to a second light emission surface. Substantially all of the light emitted from the LED incident on the second light entry surface is incident on the internal reflecting surface. The first light entry surface and the second light entry surface cooperate to prevent the light emitted from the LED from contacting the polygonal periphery.

Abstract: An LED optical assembly including an LED, a lens, and a reflector. The lens is made up of a light entry surface and a light emission surface rotated about a rotational axis. The reflector has a pair of first reflecting surfaces and a pair of second reflecting surfaces. The first reflecting surfaces are defined by a first curve rotated about the rotational axis. The second reflecting surfaces are defined by a second curve projected along the rotational axis. The lens and reflector cooperate to redirect light emitted by the LED into a vertically collimated wide angle beam of light.

Abstract: Beam forming optics having non-circular peripheral shapes are disclosed. The polygonal periphery of the disclosed beam forming optics interrupt surfaces of rotation used to define reflecting surfaces that collimate wide angle light emitted from an LED. The periphery of the lens handling narrow angle light is modified to permit light to fill the non-circular reflecting surface. The illustrated beam forming optics are configured to ensure that light emitted from the LED is handled only by surfaces configured to form the desired collimated beam.

Abstract: A light assembly comprises an LED light source, a reflector, and an optical element assembly. The LED light source comprises a light emitting die and has an optical axis which extends from the light emitting die and perpendicular to a first plane. The reflector defines an optical cavity and has a reflective surface oriented to reflect light emitted by the light source incident to the reflective surface along a range of reflected angles. The optical element assembly comprises an optical element disposed in the path of the light emitted from the light source. The optical element is supported within the optical cavity by a connector arm, which has first and second ends. The first end is connected to the optical element and the second end supports the optical element assembly from behind the reflector.

Abstract: An LED optical assembly includes a linear array of LEDs, longitudinal reflecting surfaces along each side of the array and medial reflecting surfaces between the LEDs. The medial reflecting surfaces are configured to redirect light oriented along the linear array into directions that will contribute to a light emission pattern from a warning, signaling or illumination light employing the LED optical assembly. The medial reflecting surfaces cooperate with other reflectors and/or lenses to integrate the redirected light into an intended light emission pattern.
