A light fixture with a single edge lit optical assembly produces various light distributions which provide targeted control of light output with peak intensity that is non-normal to the light guide output face. The compact form factor and modular design of the light fixture embodiments having narrow width are particularly well-suited for use in linear lighting applications requiring suspended, surface and recessed installations typically used to illuminate walls, floors and/or ceilings. The light fixture can also be selectively configured and oriented during assembly and installation to achieve various lighting distributions. Optical components within the light fixture are typically positioned and retained in optical alignment with internal support features of a linear housing. The optical assembly typically includes LED board, light guide, and one or more reflective surfaces. Additionally an optically transmitting component further provides a fixture assembler a range of design choices. A variety of light distributions can be achieved including asymmetrical and symmetrical with one or more peak intensities. Further embodiments utilize selective alignment of light guide with one or more reflectors to achieve different light distributions.

Disclosed is an outdoor light fixture assembly having a housing and a lens module. The lens module is removable from the housing for servicing. The removable lens module includes a socket for one or more light sources and a lens. The outdoor light fixture further includes engagement structures for installing and removing the lens module from the housing without the use of tools.

A downlight structure includes a light body and a light source (5). The light body includes a support (1), a movable light holder assembly (2), a base (3), and a supporting ring (4). The movable light holder assembly (2) is movably connected to a top of the support (1). The base (3) is arranged at a bottom of the support (1) after connected to the supporting ring (4). The light source (5) is arranged on the movable light holder assembly (2), and moves longitudinally or horizontally in the light with the movable light holder assembly (2). Through delicate design of the structure of the light body and the light source (5) of the downlight, the present disclosure provides a convenient solution for replacing the light source of the downlight with bare hands, and also provides a feasible solution for standardization of the downlight industry.

The present disclosure relates to a method of manufacturing a tamper proof light emitting module comprising the steps of (a) pre-assembling the light emitting module into a testing configuration including a housing and one or more light emitting elements mounted within the housing, the housing including first and second housing components connected together using at least one removable fastener connecting the first and second housing components; (b) testing the light emitting module to confirm the light emitting elements are operable; (c) after step (b), removing the removable fastener; (d) replacing the removable fastener removed in step (c) with at least one breakaway fastener; and (e) tightening the breakaway fastener(s) until the head of the breakaway fastener(s) breaks off so that the breakaway fastener(s) is no longer removable, thereby creating a final, tamper proof configuration of the light emitting module.

A luminaire, including a shade, a mounting base, a first end cap, a second end cap, a light source module and a drive power source. The shade has two first folded edges opposite to each other, and the mounting base has two second folded edges opposite to each other; the first folded edges are in snap-fit with the second folded edges; the luminaire further includes a shade pushing assembly, and the shade pushing assembly includes a force-exerting key and a pushing piece; one end of the force-exerting key is connected to the pushing piece, and the other end of the force-exerting key extends out of the mounting base; the pushing piece abuts against a first end face of at least one of the first folded edges.

A recessed light fixture has a heat sink and a removable light engine assembly. A thermally conductive base of the light engine assembly has an LED and has a thermal interface adapted for thermal coupling to a thermal interface of the heat sink. A mechanical connector in the enclosure can connect the base of the light engine assembly to the heat sink and couple the thermal interfaces of the light engine assembly and heat sink. The base of the light engine assembly is insertable through an opening in the ceiling aligned and can be urged into connected and disconnected states, from within the room, with a minimal clearance between the opening in the ceiling and the base, whereby the light engine assembly can be replaced or serviced from within the room without disturbing the ceiling and without the use of a large diameter trim.
