Abstract:
A multiple-ply solid state light fixture is disclosed. A panelized, solid state light fixture includes combined layers of material chemically bonded together without a traditional mechanical housing and with relatively few or no fasteners. In example embodiments, the solid state light fixture includes an LED mounting substrate, a thermal material on a non-LED side of the LED mounting substrate, and an optical material on the LED side of the LED mounting substrate. A plurality of LEDs are disposed or mounted, with or without additional packaging, on the LED side of the LED mounting substrate. A chemical bond is created between the substrate and the other layers. This chemical bond can be created, for example, through use of applied fluid or gelatinous compounds that are then solidified, or through the use of adhesives.
Abstract:
A mounting and locking system for a lighting apparatus is provided. The system is configured to be attached to an electrical junction box connected to a ceiling or a wall. A mounting plate that is attachable to the junction box has extension members extending from a bottom face of the mounting plate. A lighting apparatus has an upper housing assembly and at least one additional housing assembly. The upper housing assembly has a top wall and at least one sidewall. The top wall includes a mounting portion with mounting brackets that are configured to attach to respective extension members when the lighting apparatus is rotated into a locking arrangement with the mounting plate.
Abstract:
A lamp comprises an enclosure comprising a reflector and a lens where the reflector is made of thermally conductive material. A base is coupled to the enclosure. An LED is located in the enclosure and emits light when energized through an electrical path from the base. A heat sink comprises a heat dissipating portion that may be at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the LED. The reflector is thermally coupled to the heat sink and is exposed to the exterior of the lamp such that heat from the heat sink may be dissipated to the ambient environment at least partially through the reflector.
Abstract:
A lamp has an optically transmissive enclosure and a base defining a longitudinal axis of the lamp extending from the base to the free end of the enclosure. A heat sink is at least partially located in the enclosure and includes a tower that extends along the longitudinal axis of the lamp. An LED assembly is positioned in the optically transmissive enclosure. The LED assembly comprises a lead frame circuit or a flex circuit where LEDs are attached to the circuits. The lead frame and flex circuit are formed into a three-dimensional shape and are thermally coupled to the tower.
Abstract:
In one embodiment, a lamp comprises an optically transmissive enclosure. An LED array is disposed in the optically transmissive enclosure operable to emit light when energized through an electrical connection. A gas is contained in the enclosure to provide thermal coupling to the LED array. The gas may include oxygen.
Abstract:
A driver module is configured to generate the drive signals necessary to drive an LED or an array of LEDs of one or more LED luminaires. The driver module may, but need not, be located remotely from the LED luminaires. Since the driver module provides the drive signals, the LED luminaires do not need to have their own driver electronics, and as such, can be rendered in a more aesthetically pleasing and cost effective manner. As an example, the driver module may be located within a junction box or escutcheon plate associated with a light fixture and the LED luminaires can be mounted in the existing sockets of the light fixture. The internal wiring of the light fixture may be used to carry the drive signals provided by the driver module to the LED luminaires via the sockets of the light fixture.
Abstract:
A fixture comprising a light sensor and an actuator for assigning the fixture to at least one zone. A fixture comprising a light source, a motion sensor and a light sensor. A fixture comprising a motion sensor, a light sensor and a wireless transmitter (optionally also a wireless receiver). A fixture configured to detect light brightness values over a time-span, and identify a period of time with smallest average brightness. A fixture configured to dim at a first rate when a motion sensor senses no motion for a designated period of time, and optionally also configured to brighten at a second rate when the motion sensor detects motion. A fixture configured to dim to not less than a designated percentage unless motion is detected during the dimming. A lighting control system, comprising fixtures and an actuator configured to assign fixtures to zones. Also, other lighting control systems and methods.
