摘要:
The present disclosure provides an LED luminaire capable of providing full cutoff illumination in a base configuration, without the addition of reflectors or refractors. The LED luminaire is also interchangeably couplable to one or more different reflectors and refractors. In certain example embodiments, the present disclosure provides a dusk to dawn luminaire operable as a full cutoff luminaire in a base configuration and which is also compatible with an American Nation Standards Institute (ANSI) dusk to dawn reflector/refractor assembly. In an example embodiment, the LED luminaire also includes a housing with a front pivoting door configured to swing away from a mounting structure when opened.

A light diffuser having a holder device and an inflatable, at least partially light-transmissive box that can be attached to the holder device. The holder device includes an adapter ring formed by a light-transmissive disc, in particular a glass disc, for fastening to a spotlight and for connecting the inflatable box in a substantially airtight manner. The end of the inflatable box can be connected to the adapter ring which is surrounded by an airtight fastening ring that can be tensioned against a radially extending sealing surface on the adapter ring by at least three quick-closures, distributed about the circumference.

An exemplary lamp includes a first member, a second member, and buckle assemblies securing the first member on the second member. Each buckle assembly includes a connecting member having an end thereof pivotally connected to the second member, a buckle having an end thereof pivotally connected to an opposite end of the connecting member and having an opposite end thereof clasping the first member to the second member, and a knob. Each buckle assembly has a dead point. When the buckle is flapped towards the connecting member and a pivoted end between the buckle and the connecting member passes through the dead point to get close to the second member, the knob extends through the buckle. Then the knob is rotated along a predetermined direction to press on the buckle, thereby preventing the pivoted end from moving away from the second member.

A lighting assembly for a vehicle headlight, said assembly comprising: a reflector (1) defining a recess (12) serving to receive a lamp; a cover glass (2) having a back face (21) facing the reflector and a front face (22); and a cover glass support part (3) secured to the reflector (1), said support part being provided with fixing means (4, 35) for holding the cover glass (2) securely in place on said support part (3); said lighting assembly being characterized in that the fixing means (4, 35) comprise at least one member (4) forming a pressing contact portion (41) and an actuator portion (42) so as to bring the pressing contact portion into pressed contact against the cover glass (2) by moving the actuator portion, the support part (3) forming an abutment surface (or abutment points) against which the cover glass rests on its front face, the pressing contact portion coming into pressed contact against the back face of the cover glass so as to push the cover glass against the abutment surface or points of the support part. Advantageously, the assembly is provided with two members disposed, for example, in diametrically opposite manner.

A roadway luminaire is provided which includes a mast mount docking station securable to an end of a pole mast. The mast mount docking station includes a power plug electrically coupled to the power conductors. The luminaire includes a corresponding power plug which is electrically and mechanically coupled to the mast mount docking station via a twist-lock feature including mating keys and keyways in the docking station and luminaire, respectively. The luminaire includes several plug-in components such as a plug-in photoelectric cell, a plug-in starter and a capacitor press-fit into a molded cavity in the luminaire. The power plug of the luminaire is adaptable to be used with all international voltages. The twist-lock feature provides for a fool-proof mechanical and electrical connection to ensure that the correctly rated luminaire is connected to the supply voltage.

A flood light fixture for pivotable mounting to a pole or tenon is disclosed. The fixture includes a hollow mounting arm pivotably mounted to the fixture having a relieved portion defining a mounting wall. A transverse mounting bracket is slideably retained in a pair of grooves internally of the fixture housing and receives a thread fastener extending through a mounting boss on the mounting arm. A photoelectric sensor is mounted with the hollow mounting arm. Novel hinge assemblies comprising an arcuate shaped clip fastened to a flange on the housing encircles a pin on the housing cover providing for retention and pivotable movement of the cover, and a pair of wire formed latches are attached to the housing and clamp the cover to the housing.
