Abstract:
A lighting apparatus has an at least partially optically transmissive enclosure and a light source located in the enclosure that is operable to emit light when energized through an electrical path. A connector is secured to the base and is configured to receive a control module for providing control information to the LED light source. The control module is rotatably mounted relative to the enclosure. The control module may comprise a sensor that turns the light source off and on, changes the color of the light source or dims the light source upon detection of the stimulus. The enclosure has a bottom member and a mounting portion secured to the bottom support where the connector is located between the mounting portion and the bottom support.
Abstract:
A method of configuring a plurality of installed lighting units (110) comprises determining that a first installed lighting unit (110) should remain a member of a first logical group, and that a second installed lighting unit (110) should switch to a second logical group. The method further comprises interrupting a supply of electric power to the first installed lighting unit (110), e.g. via a suitable an interrupter (310), whereby the first installed lighting unit (110) is incapable of receiving a command from a controller of at least the first and second installed lighting units. The method further comprises broadcasting, from the controller, to at least the first and second installed lighting units (110), a command arranged to cause any suitable lighting unit (110) which receives it to join the second logical group, thereby causing the second installed lighting unit (110) to switch to the second logical group. The method further comprises resuming the supply of electric power to the first installed lighting unit (110) whereby it becomes operable to receive and react to commands from the controller.

Abstract:
A sealed optical street luminaire having a luminaire housing fitted with a clear, flat lens and provided with an LED light source assembly mounted in the housing. The light source assembly has a heat dissipating LED support member secured to a heat conductive adapter for securement in the luminaire housing. A reflector is secured in the luminaire housing behind the lens which is sealingly positioned about the reflector. The LED support member supports LED modules at a predetermined angle and orientation relative to an inner reflective surface of the circumferential wall of the reflector. The heat dissipating LED support member and the heat conductive adapter dissipate heat through the luminaire housing.
Abstract:
A positioning structure of an electrical element of a light emitting diode (LED) lamp for is disposed inside a lamp to clip the electrical element. The electrical element can be a power supply of the lamp or a transformer. The positioning structure includes: a base portion fixed inside the lamp, two spring arms standing upright and extending from two ends of the base portion respectively, and two clipping portions disposed on the two spring arms respectively. The two clipping portions are disposed toward each other to form a concave shape, thereby forming a contact portion in contact with the electrical element and applying a clipping force to the electrical element via the two spring arms.

Abstract:
A light emitting diode (LED) lighting arrangement for a lighting fixture includes: a lighting strip comprising a plurality of light emitting diodes (LEDs) arranged along a length of the lighting strip; a first multi-faceted side wall reflector extending from a first side of the lighting strip at an angle such that the first multi-faceted side wall reflector extends along an entire length of the lighting strip and away from a bottom portion of a light emitting portion of each of the light emitting diodes (LEDs); and a second multi-faceted side wall reflector extending from a second, opposite side of the lighting strip at an angle such that the second multi-faceted side wall reflector extends along an entire length of the lighting strip away from the bottom portion of the light emitting portion of each of the light emitting diodes (LEDs). The first and second multi-faceted side wall reflectors cause light produced by the plurality of light emitting diodes (LEDs) to be amplified and formed into a uniform beam.
Abstract:
An LED light fixture includes an integrally formed unitary housing having a first portion and second portion laterally adjacent to one another. The first and second portions at least partially define separate illuminating and wiring compartments. The illuminating compartment houses a plurality of light emitting diodes and a reflector. The illuminating compartment is partially defined by a frame and a lens mounted to the first portion of the housing. The wiring compartment has at least one wall defined by a door. The door is pivotably attached to the housing. A driver for the plurality of light emitting diodes is mounted to the door for movement with the door.
Abstract:
Provided is a detection system for a luminaire fixture including a sensor and a laser meter to allow positioning of a sensor for precise positioning toward a viewing area. The sensor includes a sensor mount to attach the detection system to an existing luminaire, a sensor lens to perceive a viewing area, and a sensor housing to protect the sensor lens. The laser meter includes a laser to project a focused light path for positioning, and a laser housing to protect the laser.

An LED light fixture including a housing, a heat sink secured with respect to the housing and an LED illuminator secured with respect to the heat sink. The heat sink includes central and peripheral portions. The central portion has an LED-supporting surface and forward, rearward and lateral sides, the LED illuminator being at the LED-supporting surface. The peripheral portion extends laterally from the lateral sides. The central portion of the heat sink has downwardly-extending shield members at the lateral sides thereof configured and dimensioned to block upward illumination. In embodiments where the optical member is configured for directing emitter light predominantly toward the forward side, the central heat-sink portion has a downwardly-extending shield member at the rearward side thereof configured and dimensioned to block rearward illumination.
