A linkable linear light emitting diode (LED) system provides apparatus and methods for mechanically, optically, and electrically linking multiple LED modules disposed over a wide and separated area of a ceiling system. Openings can be cut in ceiling tiles of a drop ceiling system and the LED lighting modules are coupled to the tile through the opening, with the tile being sandwiched between different portions of the module. A remote driver system is placed within the drop ceiling above the tiles and provides multiple connectors for powering a multitude of lighting modules. Certain of the LED lighting modules include both input and output connectors for both receiving power or data and providing power or data to other modules. In this manner, some of the modules act as master LED lighting modules and those receiving power and/or data therefrom are act as slave modules.

A light emitting diode (LED) module having a configurable LED substrate capable of receiving varying numbers and layouts of LEDs are described herein. The LED substrate includes LED coupling points for receiving the LEDs and electrical traces etched into the substrate for routing power to the LEDs. The LED module can include a multi-LED over-optic having multiple over-optics that are configured to match the number and configuration of the LEDs positioned on the substrate. The LED coupling points and over-optics can be arranged symmetrically to enable the LED module to be rotated to adjust the light output distribution and direction. The LED module can include a power connection mechanism, for example located at the center of the substrate, that also allows the LED module to be rotated. One or more of the LED modules may be mounted on a heat sink and incorporated into a light fixture.

LED luminaire assembly

A linear light emitting diode ('LED') light fixture includes LED modules that interface with one another to provide a substantially continuous array of LED's. This continuous array allows for substantially uniform light output from the LED light fixture. The LED modules can interface with one another via one or more connectors, which allow two or more LED modules to be electrically and mechanically coupled together. The connectors may be disposed beneath the LED's so that the connectors are not visible when the LED modules are coupled together. The connectors may be disposed along opposite ends of the modules to allow for end-to-end configurations of the modules and/or along side ends of the modules to allow for angled or curved configurations of the modules. The LED modules can be powered via one or more wires, magnets, or clips, which are coupled to a power source.

A multiple waveguide edge lit structure includes a frame structure. The multiple waveguide edge lit structure also includes a circuit board including a first plurality of light emitting diodes (LEDs) and a second plurality of LEDs. The multiple waveguide edge lit structure further includes a first waveguide and a second waveguide. A light receiving edge of the first waveguide is positioned proximal to the first plurality of LEDs, and a light receiving edge of the second waveguide is positioned proximal to the second plurality of LEDs. The multiple waveguide edge lit structure also includes a pair of attachment structures configured to keep the first waveguide and the second waveguide attached to the frame structure.

A lighting system is disclosed herein. The lighting system can include at least two power switches that receive power from a power source, and a power supply. The lighting system can include at least one light-emitting diode (LED) light source electrically coupled to the power supply. The lighting system can further include a dimming interface module electrically coupled to the power supply and to the at least two power switches, where the dimming interface module generates a dimming control level within a range of dimming control levels, where the dimming control level corresponds to a position of each power switch of the at least two power switches. The dimming control level can be used by the power supply to generate a dimming signal, where the dimming signal is sent by the power supply to the at least one LED light source.

Dimming interface module

In general, the disclosure relates to setting current output of an LED driver. In one embodiment, an external control module for setting a current output of an LED driver includes a plurality of voltage referenced elements. The external module also includes a plurality of switches. Each switch of the plurality of switches is coupled to a corresponding voltage referenced element of the plurality of voltage referenced elements. The external control module further includes an enclosure covering the plurality of switches, wherein the enclosure substantially prevents adjustment of switch positions of the plurality of switches. The external control module can be adjusted to set the desired output current prior to enclosing the external control module in the enclosure in connection with the assembly of a light fixture.

A multiple waveguide edge lit structure includes a frame structure including a first heat sink and a second heat sink. The multiple waveguide edge lit structure also includes a circuit board including a first plurality of light emitting diodes (LEDs) and a second plurality of LEDs, where a portion of the circuit board is sandwiched between the first heat sink and the second heat sink. The multiple waveguide edge lit structure further includes a first waveguide and a second waveguide. A light receiving edge of the first waveguide is positioned proximal to the first plurality of LEDs, and a light receiving edge of the second waveguide is positioned proximal to the second plurality of LEDs. The multiple waveguide edge lit structure also includes a pair of attachment structures configured to keep the first waveguide and the second waveguide attached to the frame structure.

A light fixture includes multiple LED modules where each LED module includes a substrate on which one or more LED's are disposed. The LED modules can interface with one another in a variety of different configurations, such that when adjacent LED modules interface with one another, there is a substantially continuous array of LED's across the LED modules. Electrical connectors or other means for powering the LED modules are disposed such that they do not impact the continuity of light across adjacent LED modules.
