A linear light fixture can include a housing that includes at least one wall that forms a cavity. The linear light fixture can also a light board having multiple light sources disposed thereon, where the light sources are arranged in a linear fashion with respect to each other on the light board, where the light board is disposed within the cavity of the housing. The linear light fixture can further include a lens slidably disposed within a receiving feature of the housing. The linear light fixture can also include a first auxiliary optical member disposed within cavity of the housing, where the first auxiliary optical member includes a first body having a first end and a second end, where the first body includes a light diffusion film. The first auxiliary optical member can fill a first gap between the lens and a first side wall of the housing.

A lighting fixture includes one or more drivers and a mounting surface. The lighting fixture can include a clamping bracket configured to secure the one or more drivers to the mounting surface. The clamping bracket can include a body. The clamping bracket can further include a first arm and a second arm. The first arm and the second arm can each extend from the body. Furthermore, the first arm and the second arm can each be bent relative to the body when the one or more drivers are secured to the mounting surface via the clamping bracket.

A backlight module and a display device are provided. The backlight module includes a back plate, a carrying member, a light guide plate, at least one optical film and a light source. The carrying member is disposed on the back plate, in which the carrying member includes a first step portion and a second step portion, and the first step portion is elevated higher than the second step portion. The light guide plate is disposed on the back plate. The at least one optical film is disposed above the light guide plate, in which the at least one optical film is held on the second step portion. The light source is disposed on the back plate, in which the light source is disposed adjacent to a light-incident surface of the light guide plate.

A luminaire comprises an optical element. The optical element comprises a coupling portion that comprises a coupling cavity that extends along a length of the optical element. The coupling cavity is configured to receive at least one light emitting diode. The optical element further comprises first and second sections extending away from the coupling portion of the optical element along the length of the coupling cavity. The first section comprises a first thickness closer to the coupling portion and a second thickness further from the coupling portion. The first thickness is greater than the second thickness. The second section comprises a third thickness closer to the coupling portion and a fourth thickness further from the coupling portion. The third thickness is greater than the fourth thickness. Light is extracted out of extraction features of opposing sides of at least one section.

A lantern system is disclosed. The lantern system can include a lantern base and a lantern shade. The lantern shade can have at least one side wall and a fastener. The at least one side wall can have at least one portion with light diffusing properties and at least one portion with light concentrating properties. The lantern shade can be removably coupled the base via the fastener. The lantern base can include at least one leg to attach a strap of a headlamp to the lantern base.

Provided is a lamp assembly, including: a housing including a bottom portion and side wall portions forming a light source mount portion in a longitudinal direction, a flange portion being connected to each front end of the side wall portions and forming a first insertion portion with an inner side surface thereof being open, and a second insertion portion provided on a bottom surface of the first insertion portion; a lampshade provided therein with a light source, and coupled to the mount portion; a translucent panel slidably coupled to the first insertion portion; a packing fitted in the second insertion portion; and a press bar being inserted in the first insertion portion between an upper surface of the flange portion and the translucent panel and pressing the translucent panel and the packing, thereby fixing the translucent panel and endowing the packing with watertightness.

An embodiment of the present invention relates to a phosphor plate, which is a plate-shaped photo-conversion structure in which a phosphor is dispersed inside of a glass matrix, and has an uneven surface comprising at least one type of pattern, formed on at least one surface of the both surfaces of the plate, wherein the pattern occupies 70-95% of the area of the one surface.

The present invention relates to different embodiments of lighting fixtures, such as troffers. A lens can be placed between a light engine and a reflector and secured in place by crimping portions of the light engine, reflector, or both to prevent the lens from moving. Troffers according to the present invention can lack a dedicated heat sink, instead sufficiently dissipating heat through the light engine. This can significantly reduce the weight of the troffer. Emitter panels can be directly mounted on a light engine inner surface, or on an internal reflector within the light engine.
