A lighting device (5) is disclosed. The lighting device (5) comprises a plurality of light-emitting filaments (10), wherein each of the light-emitting filaments (10) comprises a plurality of solid-state light sources mounted on a carrier along a longitudinal axis of the light-emitting filament (10). The light-emitting filaments (10) are arranged in a planar configuration, and the lighting device (5) has a main direction of illumination (I) perpendicularly away from a plane (P) defined by the planar configuration. The longitudinal axes (L1, L2) of at least two light-emitting filaments (10) are non-parallel to each other. A luminaire comprising the lighting device is also disclosed. The lighting device (5) can be produced in a cost-efficient manner.

A modular light emitting diode (LED) mounting configuration is provided including a light source module having a plurality of pre-packaged LEDs arranged in a serial array. The module includes a heat conductive body portion adapted to conduct heat generated by the LEDs to an adjacent heat sink. As a result, the LEDs are able to be operated with a higher current than normally allowed. Thus, brightness and performance of the LEDs is increased without decreasing the life expectancy of the LEDs. The LED modules can be used in a variety of illumination applications employing one or more modules.

The present disclosure provides a multi-directional light fixture having a single orientation light source. The multi-directional light fixture includes a light source orientated towards a semi-reflective lens. The semi-reflective lens allows a portion of the light it receives from the light source to be reflected upwards, providing uplight from the light fixture. The lens also allows a portion of the light it receives from the light source to be transmitted therethrough, providing downlight from the light fixture. Thus, the light fixture provides both uplight and downlight while the light source is oriented downwards.

A lighting fixture includes a housing channel and a heat sink assembly coupled to the housing channel. The heat sink assembly includes a heat sink base and a heat sink clamp that are coupled together via a fastener to retain a waveguide to the lighting fixture. In particular, the fastener is disposed at an acute angle relative to the respective waveguide. Further, the lighting fixture includes one or more light sources coupled to the heat sink base and oriented such that light emitted by the one or more light sources enters an edge of the waveguide. Furthermore, the lighting fixture includes an end cap that covers an open lateral end of the housing channel. Further, the end cap operates as an alignment bracket to couple the lighting fixture to a second lighting fixture adjacent the open lateral end of the housing channel of the lighting fixture.

A lighting assembly comprising a light source operable to emit light, a first primary optic, and a second primary optic. Each of the first primary optic and the second primary optic are configured so as to reflect light incident thereupon to be emitted by the lighting assembly. Additionally, each of the first primary optic and the second primary optic are positioned such that a first portion of light emitted by the light source is incident upon the first primary optic and a second portion of light emitted by the light source is incident upon the second primary optic. At least one of the first primary optic and the second primary optic is operable to me rotated to change the relative position thereof with respect to the light source.

A luminaire can comprise at a light source, a lightguide, and a reflective surface. The lightguide can comprise two major surfaces, for example two faces of a panel of optical material. The light source can couple light into the lightguide through an edge of the lightguide. The coupled light can exit the lightguide through the major faces of the lightguide. The reflective surface can be oriented to receive and redirect the light emitted from the lightguide. Via this redirection, the luminaire can emit illumination in direction that is different from the light source's emissions. For example, the light source can emit light upward and into the lightguide, the lightguide can emit and distribute that light outward, and the reflective surface can redirect the light downward.
