Abstract: A surface mounted LED light structure has a V-shaped channel with opposed legs and a flat central portion. A flat base strip is attached to each leg. The strips each have a pair of electrically conductive traces. A plurality of LEDs is arrayed along the base strips and electrically connected to the traces. A diffuser is disposed over the LEDs. A spacer sleeve holds the diffuser over the channel central portion. A driver is mounted adjacent the channel and is connected to the conductive traces and to the power source.

Abstract: In a first aspect of the subject invention, an LED light assembly is provided comprising: a housing; and, a plurality of LED light modules coupled together in axial end-to-end fashion so as to define an elongated lighting strip, each said light module including at least one heat dissipation block and at least one LED element, wherein, said lighting strip is secured to said housing.

Abstract: A LED light fixture is provided herein for mounting into a troffer housing. The light fixture includes a carrier plate dimensioned to fit within the troffer housing, the carrier plate having a generally flat first portion, a generally flat second portion, and an outwardly indented portion located therebetween. The first and second portions are generally coplanar in a common plane. At least one LED is mounted to the first portion. A driver is electrically coupled to the at least one LED and disposed within the indented portion without extending through the common plane with the driver being fixed to the carrier plate. At least two lead wires are electrically coupled to the driver, and extending therefrom, configured to allow electrical power to pass therethrough to the driver. Advantageously, a LED light fixture is provided herein which is a unitary construction that can be efficiently mounted in a troffer housing.

Abstract: A dimming control and driver for an LED luminaire comprises a shutdown relay connected between an AC source and the driver circuit. The shutdown relay will close above a predetermined control voltage, and will open below the predetermined voltage. The shutdown relay will eliminate parasitic loss by turning the power completely off when the LED luminaire is turned off.

Abstract: An adjustable bi-level lighting control is for use in connection with LED luminaires having an LED, a current control circuit, a driver circuit and an AC source. The LED luminaire is directed to illuminate an area having intermittent occupancy. The adjustable bi-level lighting control comprises a dimmer supplying a first control signal to the current control circuit, to control current flow to the LED. An occupancy sensor, responsive to an occupant entering the area, supplies a second electrical control signal to the dimmer. An adjustable control connected to the dimmer allows for selective adjustment of the first electrical control signal. Low and high level potentiometers selectively adjust the first electrical control signal to low and high levels, thereby selectively adjusting the LED to low and high levels of intensity, respectively.

Abstract: An LED-based luminaire employs an LED module mounted to a housing. The LED module is advantageously configured to transmit heat generated by the LEDs across and/or through the module and to the housing for dispersal to the environment. LED modules can be configured with conductive or non-conductive cores, and may be configured to evacuate heat from one or both faces of the LED module. Further, multiple heat paths can be defined from components on an LED module to the housing and to the environment.

Abstract: The present disclosure generally relates to several embodiments of a new illumination device using a plurality of LEDs, the device is designed to better diffuse heat produced from a heating driver circuitry and the LEDs in a way that allows for either the operating or equilibrium temperatures of the heat sensitive elements as part of the device to be subject to less stringent temperature increases and therefore improve the viability and energy performance of the device. The new design includes toroid-shaped external rings for the plurality of LEDs and a middle opening for the driver circuitry. The new design further includes fins and the use of different spaces and openings within the housing to help control the flow of heat by way of thermal conduction, thermal convection, or thermal irradiation.

Abstract: A light emitting diode (“LED”) illumination device includes a substantially rigid reflector cover having a plurality of open air reflectors, a circuit board having a plurality of LED packages and a plurality of thermal vias disposed in the circuit board in the vicinity of each LED package thereby defining a pressure zone, and a mounting bracket that functions as a heat sink The base of each open air reflector is dimensioned to cover at least a portion of the pressure zone. Fasteners are used to mechanically couple the reflector cover to the circuit board and the mounting bracket and to create pressure on the thermal vias in the pressure zone. In operation, heat created from operation of the LED illumination device is effectively dissipated into the atmosphere and is simultaneously pulled away from the LED packages through the plurality of thermal vias to the mounting bracket.
