An LED luminaire with reduced glare provides a polar arrayed light gradient on a diffuser lens and replicates the appearance of a filament or tube lamp. The luminaire includes a housing having an opening, a diffuser lens extending across the opening, and a plurality of LEDs positioned within the housing behind the diffuser lens. The plurality of LEDs are arranged to generate a composite light pattern having a polar arrayed light gradient across an aperture of the diffuser lens. The polar arrayed light gradient has a light intensity that decreases concentrically with increasing radius.

The present disclosure provides an LED based light unit that produces an output lighting pattern that meets desired lighting characteristics using a reduced number of LED elements. The present disclosure provides a number of point sources that are directed into a desired direction such that, when combined with other point sources, a synthesized light output is provided that minimizes the LED headcount.

A ceiling light LED retrofit kit is provided. The kit is configured for attachment to an existing, installed linear fluorescent tube lighting fixture. The kit includes a light panel, a first profile extending along a first longitudinal side of the existing fluorescent light fixture, and a second profile extending along a second longitudinal side of an existing light fixture. The retrofit kit light panel includes light emitting diodes. A raceway may be defined between the retrofit kit and the previously-installed fixture, in which wiring and other components may reside away from you.

The present invention provides a display device having a direct-lit type light guide plate with a curved surface, including a light guide plate with a curved surface. The curved surface of the light guide plate with a curved surface is formed by a plurality of strip-shaped sections connected in parallel with each other.

In addition, a plurality of direct-type light sources are included, the direct-type light sources arranged in more than one row, and each row of the direct type lights corresponds to each of the strip-shaped grooves.

An intelligent type lamp and a vehicle lamp apparatus are disclosed. The lamp includes a first substrate, a second substrate disposed on the first substrate, and a plurality of light sources disposed on the second substrate, wherein the light sources are grouped into at least one light source array, in each of which the light sources are disposed in a line, and the at least one light source array includes neighboring first and second light source arrays electrically isolated and individually driven. The light sources of the first light source array may be electrically isolated and individually driven, and the light sources of the second light source array may be electrically isolated and individually driven. Alternatively, the light sources of the first light source array may be electrically isolated and individually driven, and the light sources of the second light source array may be electrically connected and simultaneously driven.

There is disclosed alighting device (8) comprising: at least one light-emitting filament comprising (12) a plurality of solid-state light sources (14); and an elongated reflector (9) arranged to reflect light emitted by the light-emitting filament (12), wherein the reflector (9) has a longitudinal groove (11) in which the light-emitting filament (12) is arranged such that the reflector (9) and the at least one light-emitting filament (12) extend longitudinally along a common path, and wherein said path is curved in three dimensions. A light bulb (5) comprising the lighting device (8) and a luminaire (1) comprising the lighting device (8) are also disclosed. The lighting device (8) can be produced cost-efficiently and adapted to conform well to a predetermined emission pattern.

A lighting engine, system and method of fabrication are described. The system contains a flexible printed circuit (FPC) shaped as a loop. LEDs are mounted on the FPC to emit light toward a center of the loop. A light guide positioned in an interior of the loop receives light emitted by the LEDs through an edge of the light guide. The light guide has slots formed therein that receive locator pins to limit thermal displacement of the light guide towards the LEDs. Other apparatuses, systems, and methods are also disclosed.

A lighting device is disclosed in the present disclosure. The lighting device includes a support assembly, an illuminant assembly, and a switch assembly. The illuminant assembly is connected to the support assembly and capable of being rotated to the support assembly. When the illuminant assembly is rotated to a position at which an angle between the illuminant assembly and the support assembly is less than or equal to a first angle threshold, the switch assembly turns to an on-state. In this way, the lighting device has a function of a switch.

This disclosure discloses a light-emitting bulb. The light-emitting bulb includes a cover, an electrical associated with the cover, a board arranged between the cover and the electrical connector, and a first light-emitting device disposed on the board. The first light-emitting device includes a carrier having a first side and a second side, a first electrode part disposed near the first side and extending to the second side, a bended part disposed near to the second side and spaced apart from the first electrode part, and a second electrode part extending from the bended part to the first side. No light-emitting diode unit is arranged on the second electrode part.

Arc modular light devices, systems, and methods. In at least one exemplary embodiment of a module system of the present disclosure, the module system comprises a plurality of LED modules, each LED module comprising an outer housing, a light source positioned within the outer housing, and a lens positioned so that light from the light source can be emitted through the lens; and a plate configured to couple to each of the plurality of LED modules; wherein the module system is configured to focus light from the LED modules inward when the plate has a concave curvature; and wherein the module system is configured to spread light from the LED modules outward when the plate has a convex curvature.
