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 an 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 electronics package includes an electronic component having a light emitting diode (LED) and a protective case encapsulating the electronic component. An optical system is arranged between the electronic component and the protective case. The optical system is maneuvered to one of multiple positions via an actuator that is coupled to the optical system, where the actuator is accessible external to the protective case by the user of the electronics package. A first position of the optical system allows the light generated by the LED to be collected and/or controlled by the optical system. A second position of the optical system allows the light generated by the LED to be unaffected by the optical system. A third position of the optical system allows at least a portion of the light generated by the LED to be collected and/or controlled by the optical system and the remaining portion to be unaffected.
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.
