A lighting fixture arranged and configured for use in an anti-ligature or ligature resistant environment or facility is disclosed. In one embodiment, the lighting fixture includes an inset door The lighting fixture includes an angled or beveled edge, wall, or surface along an outer periphery of the inset door so that a beveled, enlarged triangular opening is formed between the inset door and the enclosure of the lighting fixture. In use, the beveled opening eliminates any channel or access point between the inset door and the enclosure in which an object may be wedged.

The invention provides an assembly comprising a locking element and a plug module (20) connected to a socket (30); the locking element (10) comprising: a fastening means (12) configured to constrain a rotation of the locking element around the centerline of the socket; a main body (13) comprising a circumference; at least one spring plate (11) coupled to the main body and freely extending along a part of said circumference; wherein the at least one spring plate is deflectable between an initial position and a deflected position, wherein in the initial position the at least one spring plate protrudes in the axial direction of the centerline, the at least one spring plate being configured to engage a base surface of the plug module and to deflect away from said initial position into the deflected position, thus enabling the rotational movement of the plug module in the first rotational direction.

A luminaire (100) has an elongate tubular shell (1) and an elongate internal chassis (2) within the shell dividing space within the shell between a first compartment for electrical components and a second compartment for optical components (7, 6). The luminaire has a sealing cap (3, 4) at each end, and at least one of which supports an auxiliary active component for an application such as emergency lighting or car parking management. The shell (1) has features 1(a) for desired optical properties. The only seals are at the ends, between the end caps and the shell, and these are via sealing rings (17).

A light emitting diode luminaire with effective heat dissipation. The luminaire includes a luminaire housing, an LED light module having at least one LED mounted to a circuit board, a first thermal interface, and a second thermal interface. At least a portion of the first thermal interface is interposed between the circuit board and the second thermal interface. At least a portion of the second thermal interface is interposed between the first thermal interface and the luminaire housing. The first thermal interface and the second thermal interface provide a conductive path for heat from the circuit board to the luminaire housing.

A laser light decorative lighting apparatus. The laser light decorative lighting apparatus including a laser light source generating a light and a motion assembly. The motion assembly including an articulating optical element disposed in a path of the light being generated by the laser light source and a motor coupled to the articulating element such that a movement generated by the motor drives the articulating optical element. The motion assembly being configured such that the movement driving the articulating optical element by the motor causes the light to move across a surface onto which the light is being projected in a pattern.

A streetlight apparatus and method involves use of an anti-theft material for deterring theft of electrical wiring from a streetlight. The anti-theft material includes a stack of rings encircling the electrical wiring in the chamber of the base of the streetlight, where each ring of the stack of rings may include a plurality of ring segments that are each individually insertable through an access opening of the base of the streetlight and positioned around the electrical wiring.
