Abstract:
An LED based light and a method of providing power to the LED are disclosed. The LED based light includes at least one LED and at least one thermoelectric generator having a first side and a second side. The first side is thermally coupled to the at least one LED such that heat generated by the at least one LED is conducted to the at least one thermoelectric generator, producing a temperature differential between the first side and second side. The at least one thermoelectric generator is configured to produce electrical energy from the temperature differential.
Abstract:
Disclosed herein is a replacement light for a fluorescent tube usable in a fluorescent fixture. The light includes a housing having a first end and a second end opposite the first end. A support structure is disposed within the housing. At least one LED is positioned within the housing and is arranged on the support structure. A first seal has at least one aperture and is disposed within the first end of the housing. The first seal is configured to conform to an inner circumference of the first end of the housing. At least one electrical connector extends through the at least one aperture is and connectable to the fluorescent fixture.
Abstract:
An LED-based light can include a highly thermally conductive base having multiple radially outward projecting nodes. The nodes can be spaced apart in an axial and circumferential directions of the base. An electrical connector and at least one LED can be attached to the base, and a light transmitting bulb can be attached to the base and can cover the at least one LED. The geometry of the base can promote heat dissipation, which can allow the at least one LED to use enough power to produce an amount of luminosity that allows the LED-based light to replicate, for example, an incandescent light without overheating.
Abstract:
A lighting and communication system for use in a standardized light fixture is provided. The lighting and communication system includes a light source and a communication apparatus including at least one of an audio device and a camera. At least one electrical connector configured for physical and electrical connection to the standardized light fixture is included, and the at least one electrical connector is electrically connected to the light source and the communication apparatus.
Abstract:
An emergency lighting system for a building includes at least one LED-based light. An emergency detector is operable to detect an emergency. The emergency detector produces an emergency signal in response to the emergency. A controller is operable to control the at least one LED-based light in response to the emergency signal.
Abstract:
An LED-based light for replacing a conventional fluorescent tube in a fixture is provided. The LED-based light includes an elongate light transmitting rod defining a bore and at least one LED positioned at one or both ends of the rod and oriented to produce light longitudinally into a portion of the rod radially outward of the bore. At least one connector is physically coupled to an end of the rod and electrically coupled to the at least one LED. The at least one connector is adapted for physical and electrical connection to the fixture. In operation, the directional light produced by the at least one LED is dispersed by way of reflection, refraction, and/or diffusion while traveling longitudinally through the rod to reduce the appearance of bright spots.
Abstract:
An LED-based light includes a support structure. At least one oscillator is connected to the support structure. At least one LED is coupled to each oscillator. The oscillator can oscillate the LED to produce a light blurring effect.
Abstract:
Disclosed herein are embodiments of a LED fluorescent tube replacement lamp and lighting modules from which the lamp is constructed. One embodiment of a replacement lamp includes a plurality of interchangeable lighting modules that are configured to be electrically connected to adjacent modules. The interchangeable lighting modules can include end modules each having an end cap with pin connectors, at least one of the end modules includes electrical circuitry connected to the pin connectors for powering the modules. The lighting modules can also be center unit modules having LEDs mounted to a circuit board. The replacement lamps can be made from conceivable configurations of the lighting modules, requiring removal of only one module for repair or replacement.
Abstract:
An LED based light comprises a base, a light structure, a heat dissipating structure, and at least one LED. The light structure is adjacent to the base and extends along a longitudinal axis of the light. The light structure includes an inner surface and an outer surface and defines a cavity, and the heat dissipating structure extends into the cavity. At least one LED is mounted in thermally conductive relation to the heat dissipating structure. In one version, the light structure is an annular flange, and an organic LED is mounted to the outer surface. In another version, the light structure is a light pipe configured to distribute a light produced by the at least one LED in a predetermined light distribution.
