Abstract: A method and apparatus for collecting and projecting light into a specified target illuminance. A lens may be mounted or otherwise paired to a carrier to form a lens/carrier combination, which may then be mounted to a printed circuit board containing a light emitting diode (LED). The lens/carrier combination may establish an optimum optical relationship between the LED and the lens, such that a predetermined photometric distribution of the LED is collected by the lens, while the remaining photometric distribution of the LED is rejected by the carrier. The photometric distribution of neighboring LEDs, if any, may also be rejected by the carrier so that interference light may not be allowed into any lens. A diffuser may then spread the specified target illuminance into a beam pattern that may be compliant with specific standards (e.g., Department of Transportation or Economic Commission for Europe standards).

Abstract: A lens system including one or more insertable lenses that are secured from movement relative to a protective transparent media that itself is securable to a lighting enclosure with a light source in the lighting enclosure. The insertable lenses can be removable or alternately oriented to alter the distribution of light or the projection direction of light, respectively.

Abstract: A lighting fixture for protecting and mounting an array of light sources such as LED modules. The fixture includes a frame with a first surface that arcs or curves with an arc angle of between ten and fifty degrees and an arc length of between about ten to fifteen times the arc height. A plurality of LED modules including a lens and bonnet reflector are each functionally coupled against the first surface to direct a combination refracted and reflected beam pattern, the beam pattern of each LED module having a peak luminous intensity directed substantially normally from the first surface in front of and against which each LED module is functionally coupled. The peak luminous intensity of the combination refracted and reflected beam pattern associated with each LED module has a positive angle with respect to the combination refracted and reflected beam pattern from adjacently located LED modules.

Abstract: An LED lamp is placed in service on an automotive vehicle to enhance nighttime visual ability or anywhere where increased lighting is needed. The LED lamp utilizes a multi-stage power and control design, where the LED drive current is managed by an LED constant current controller that is coupled to a microprocessor that commands the intensity value of an LED array. The microprocessor manages the light intensity of the LED array using well known pulse-width modulation control methods. The microprocessor measures the voltage of the DC power source and to detect when DC power is removed. Once this detection has occurred, the microprocessor signals the LED current controller to change the current operational mode being delivered to the LED array to the next available operational mode, or alternatively, to the next appropriate operational mode to be used as determined by software stored within the microprocessor.

Abstract: A lighting fixture includes a plurality of light sources and an auxiliary component bay. The light sources and auxiliary component bay may be independently energized to cause one or more of the plurality of light fixtures to illuminate and/or to energize an auxiliary electronic component that is removably coupled to the auxiliary component bay. The auxiliary electronic component may include a camera, a battery pack, a work light or any other electronic device that may utilize operational power from a vehicle to perform a function. The auxiliary electronic component may include its own power converter which may accept a vehicular power signal to derive operation power therefrom. The lighting fixture may produce a beam pattern that is optimized for use when the auxiliary electronic component includes a camera. The auxiliary electronic component may be cooled by a thermoelectric device coupled to the component bay.
