Light fixture with edgelit optical element for direct downlighting applications
Various light fixtures are provided for mounting within and below suspended grid ceilings incorporating T-bars and ceiling panels. The light fixtures comprise a double or single edgelit planar or wedge shaped optical element that functions simultaneously as an outcoupling TIR light guide and a light scatterer or direct throughput lens. It provides a number of benefits because of its edgelit design including; thin forms and shallow depth, extended emitting area and controlled lighting distributions from one or two light guide faces. Additionally, areas typically dedicated to bezels or edge reflectors can be greatly reduced or eliminated due to decreased hotspotting to provide a fixture face with very high percentage of light emitting area. Embodiments are described for direct, indirect, and direct indirect configurations. The embodiments provide increased light output, uniformity of brightness and color and controlled direct and indirect lighting distributions and with single or dual off axis intensity peaks. Such light distributions are particularly useful in applications such as direct illumination of offices, schools, hospitals, retail or commercial spaces and table tops or work surfaces or indirect illumination of ceilings, wall washing and surface area lighting as well as other lighting applications.

A optically transmissive component is configured within a light fixture to provide benefits in brightness uniformity and visual appearance with the use of a light scattering extension portion that provides light scattering of light emitted from near an input edge of a light guide or other edgelit optical element. The sequential propagation of light through both the extension portion and main portion of the optically transmissive component significantly reduces the higher brightness and uneven “hotspotting” type visual defects typically produced near the input edge of an edgelit optical system. With appearance constraints removed or reduced, edgelit light fixtures with higher output, higher efficacy, and/or simplified edgelit optical components are enabled. Embodiments include the use of the extension portion of the optically transmissive component extension to mechanically position and retain an edgelit optical element within a light fixture.
A light fixture delivering electrically controlled lighting distributions for mounting within an installed panel system typically used in ceiling and wall constructions and incorporating acoustic, drywall or wood panels. The light fixture can provide low-glare or wide spread “batwing” ambient light or more directional wall wash, task and accent lighting. The light fixture comprises one or more LED boards and an optical element which can be back-lit or edge-lit. The light fixture body is configurable, comprising a 3-dimensional extruded elongate body with its ends cut at a configured angle. The body typically comprises additional side support features that support and enclose the edge of installed panels. In the case of a T-bar based ceiling grid system the side support features may also replicate the function and appearance of T-bar horizontal and vertical portions. The body comprises features to retain and align LED boards, reflectors and a back-lit or edge-lit optical element. In the edge-lit configuration the optical element may also be a light guide. The edge-lit design also enables the height of the lighting assembly body to be equivalent to or less than the height of T-bar main beams or cross tees. This is very important in applications where there is zero or little available plenum space above the ceiling grid. Because the lighting assembly can also provide structural support within the installed panel system it can replace one or more T-bars and can also be used to connect one or more T-bars or other structural grid elements. The lighting fixture can be mounted at an oblique or diagonal angle to the typical square grid layouts, or in a corner of a ceiling grid T-bar cell at the intersection of one or more T-bars. Additionally, more than one elongate bodies can be connected to form square, crosses, curves or arcs or more complex shapes. The electrical power may additionally be configured to control lighting distributions of the fixtures independently of one another.

Disclosed is a lighting assembly for providing electrically configured light distributions and illumination patterns. The light distributions can be pre-configured and stored in a memory device or adjusted once installed in an environment by use of a wired or wireless controller or control device. The lighting assembly comprises at least one primary transmissive optical element and multiple light sources arranged in two or more independently addressed electrical channels spatially arranged on a common plane of the lighting assembly housing. Each light source channel is both physically separated and electrically adjustable in order to control light input into the optical element and subsequently adjust the light distribution output of the lighting assembly. The lighting assembly can be used to provide a wide range of symmetric and asymmetric lighting distributions for direct or indirect lighting as well as focusing or defocusing a projected beam in a spotlight or downlight configuration. The lighting assembly is therefore useful in a wide range of typical indoor and outdoor lighting applications including downlighting, spotlighting, wall washing, cove lighting, retail lighting, warehouse lighting. It is also possible to produce useful tunable white or color related lighting effects wherein different color temperature variants of white or different colors, such as red, green or blue might have different lighting distributions.
A lighting assembly includes at least one light source array provided in a housing and a light scattering primary transmissive optical element having at least one focal region positioned substantially parallel or concentric with the light source array. Lens features of the optical element may include a Fresnel lens pattern to produce at least one focal region. An auxiliary transmissive optical element may be provided to further control light distribution and brightness uniformity.
A single edge lit lighting module is disclosed which produces tailored light distributions valuable in many illumination applications. The lighting module comprises a unique light scattering optical element which is aligned with one or more LED light sources along one of its edges and works in combination with configured reflective surfaces. Light distributions attainable using the invention include, but are not limited to, symmetric and asymmetric bi-lobed “batwing” distributions for wide area direct and indirect lighting, and tilted or asymmetric distributions for perimeter lighting. It is also possible to achieve more rounded and symmetric distributions by an additional diffuser as a cover lens. The invention's unique single edge lit construction provides the means for achieving the lighting distributions without the need for conventional two lit edges and within a compact form factor with narrow width. The invention is particularly well-suited for linear lighting fixtures that are surface mounted, suspended or recessed. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by controlling the input signals to the LED board included in the assembly.
