A lighting device (10) is disclosed comprising a glass housing (20) delimiting an optical chamber (21), wherein at least one solid state lighting (SSL) element (30) is mounted within the optical chamber. The optical chamber (21) further comprises a light exit window (50) mounted in an aperture (23) of the optical chamber opposite the at least one solid state lighting element, the light exit window comprising a sealing plate sealed to the glass housing by a glass seal (51); and a light-transmissive thermal barrier (40) extending across the optical chamber in between the sealing plate and the at least one solid state lighting element, which protects the at least one SSL element (30) from thermal damage during the formation of the glass seal (51). Also disclosed are a luminaire including such a lighting device and a method of manufacturing such a lighting device.

Various aspects and embodiments of under-hood luminaires are described. In one example, an under-hood luminaire includes a luminaire frame assembly. The luminaire frame assembly includes support braces and a number of cross members secured to the support braces in a spaced-apart configuration. The cross members include mounting surfaces, and light strips are secured to the mounting surfaces. The luminaire also includes a contraction hook assembly that can be used to secure the under-hood luminaire to the hood of an automobile. The luminaire can be relied upon to uniformly illuminate the engine compartment of the automobile, helping to eliminate lost productivity and frustration for mechanics.

A wall pack light fixture including a front cover having a front surface, a top wall, and two side walls, the top and side walls extending rearward from the front surface and defining a recess with an inner contact surface, a light element in the front cover, a rear enclosure having a forward-facing front edge, and a hinge having a first portion connected to the front cover and a second portion pivotably coupled to the first portion, the second portion connected to the rear enclosure, wherein the front cover is rotatable about the hinge between a closed configuration, in which the forward-facing front edge is within the recess and against the inner contact surface, and an open configuration, wherein the top wall of the front cover is a continuous surface which, in the closed configuration, extends over a top portion of the forward-facing front edge of the rear enclosure.

A LED lamp for use in a lamp housing of a vehicle comprises a bulb body and a base. The bulb body comprises one or more light-emitting diodes. The base comprises a mounting portion and a heatsink portion. The mounting portion comprises a collar configured to attachably accept one end of the bulb body, and one or more mounting tabs configured to engage with the lamp housing to secure the LED lamp in place within the lamp housing. The mounting portion is integrally formed with the heatsink portion, and the bulb body is configured to be rotatable within the collar about a longitudinal axis of the LED lamp.

A apparatus to cover a lighting apparatus is provided. The apparatus includes a flexible material couplable to a lighting apparatus. A portion of the flexible material to cover a light-emitting surface of the lighting apparatus is transparent.

The present disclosure discloses a mounting assembly for an optical element of a lighting lamp, including a base, a top frame and at least two side frames, one end of each of the at least two side frames is connected to the base and the other end is connected to the top frame; the at least two side frames, the base and the top frame enclose a mounting space for fixing the optical element, and the at least two side frames are configured to be distributed around the optical element and are configured to be connected to a side edge of the optical element. The present disclosure further discloses a light source module and a lighting lamp.

A lighting fixture includes a first housing portion and a second housing portion. The first housing portion includes a base and a wall extending outwardly from substantially the perimeter of the base. A top portion of the wall includes one or more hinges extending outwardly therefrom. The second housing portion includes a front panel and a side panel extending outwardly from substantially the perimeter of the front panel. A top portion of the front panel includes at least one slot. The second housing is coupled to the first housing in an open position when the hinge is inserted into the slot and the front panel is disposed elevationally above the base. The second housing is coupled to the first housing in an operational position when the hinge is inserted into the slot and the front panel covers the base.

Accessories for LED lamp systems and methods of attaching accessories to illumination sources (e.g., LED lamps) are disclosed. A beam shaping accessories mechanically affixed to the LED lamp. The lens is designed to adapt to a first fixture that is mechanically attached to the lens. Accessories are designed to have a second fixture for mating to the first fixture such that the first fixture and the second fixture are configured to produce a retaining force between the first accessory and the lens. The retaining force is a mechanical force that is accomplished by mechanical mating of mechanical fixtures, or the retaining force is a magnetic force and is accomplished by magnetic fixtures configured to have attracting magnetic forces. In some embodiments, the accessory is treated to modulate an emanated light pattern (e.g., a rectangular, or square, or oval, or circular or diffused emanated light pattern). A USB connector is also provided.

A method for manufacturing a light guide plate (LGP) positioning block thereof includes providing a positioning block body of a LGP positioning block and filling and sealing a liquid in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.
