A lighting fixture and method of providing lighting is provided herein that utilizes both direct and indirect light sources. The direct and indirect light sources can be provided in arrays of light emitting diodes (LEDs) oriented along desired axes. In some versions, the light fixtures described herein include a direct lighting array having one or more LEDs oriented to project light downwardly and an indirect lighting array having a plurality of LEDs oriented to project light in a transverse direction. Further, the light fixtures can include an indirect lighting member configured to be illuminated by the plurality of LEDs of the indirect lighting array. Additionally, or alternatively, the light fixtures described herein can include one or more controllers that are configured to independently operate the direct and indirect lighting arrays. Moreover, the indirect lighting array can be configured to emit light in a plurality of colors to visually convey information.

A strip light has a lamp holder, a light source module, an optical assembly, and two end cover assemblies. The first end cover assembly has an outer cover fixedly connected with the end of the strip-shaped lamp holder and a male socket electrically connected with the light source module, the second end cover assembly has an outer cover fixedly connected with the end of the strip-shaped lamp holder and a female socket electrically connected with the light source module, and the male socket is provided with at least two contact pins. The outer cover is provided with a jack for accommodating the contact pin, a separation part for separating the contact pin is arranged in the jack, the tail end of the contact pin is positioned on the inner side of the tail end of the separation part, and a safe distance is formed between the two tail ends.

A grow light for providing light to one or more plants in a grow area, includes a first light source and a second light source. A first energy conversion component is disposed over the first light source and a second energy conversion component is disposed over the second light source. A power supply is configured to provide power to the first and the second light sources. A controller is configured to control the power supply to provide power to either the first light source or the second light source at a given time. The first energy conversion component converts light received from the first light source into a light having first spectrum and the second energy conversion component converts light received from the second light source into a light having second spectrum different from the first spectrum.

A heat sink for use in a lighting assembly and including a hexagonal body extending a length. The body including an outer surface, an inner surface opposite the outer surface, a lumen defined by the inner surface, at least one hole extending through the hexagonal body from the inner surface to the outer surface, first, second, third, fourth, fifth, and sixth body portions extending the length. The first, second, and third body portions including planar surfaces extending the length. Each of the first, second, and third body portions configured to support an LED strip thereon. The fourth, fifth, and sixth body portions including fins extending outward therefrom. The inner surface including a plurality of fins extending inward and positioned around a perimeter thereof.

The present invention includes a pane unit (1), which comprises a frame structure (2), an illuminable pane (4), a lighting element (5), and a receptacle (8) therefor, wherein a homogeneous light field is generated by the lighting, with, e.g. the lighting element (5), of at least one narrow side (7) of the illuminable pane (4).

According to an aspect of the present disclosure, a luminaire comprises a plurality of waveguides, a light source arranged to direct light into the plurality of waveguides, and a plurality of extraction feature patterns. The luminaire contemplated by the present disclosure is arranged with the plurality of waveguides are aligned such that an extraction feature pattern extracts light out of a first waveguide of the plurality of waveguides and a second extraction feature pattern extracts light out of a second waveguide of the plurality of waveguides. Further, in accordance with this aspect, the light extracted out of the first waveguide is directed through the second waveguide to develop an appearance of depth.

A ceiling lamp, an LED light source module, and a light source assembly are provided. The light source assembly includes a plastic heat-dissipating member and a metal substrate for mounting LED light sources of the ceiling lamp. The plastic heat-dissipating member includes an embedding groove, and the metal substrate is embedded in the embedding groove and is in contact with groove walls of the embedding groove. The light source assembly can effectively balance safety, performance and cost.

The present invention discloses a light emitting device. The light emitting device includes a housing, a first light emitting module and a second light emitting module. The first light emitting module is provided with a first light emitting area and is disposed on the housing. The second light emitting module is provided with a second light emitting area and is disposed on the housing and surrounds the first light emitting module.
