LED luminaire assembly

摘要

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.

1. An illumination device, comprising:
a substrate; an electrical trace disposed on the substrate; a plurality of LED coupling points disposed on the substrate and electrically coupled to the electrical trace; and a multi-LED over-optic comprising a base surface and a plurality of discrete over-optics, wherein the base surface comprises one or more mounting posts, the one or more mounting posts being in contact with the substrate, wherein each of the plurality of discrete over-optics has a substantially concave shape defining a cavity, the cavity having a closed end defined by the discrete over-optic and an open end facing towards the substrate, the closed end of the cavity of the discrete over-optic extending from a top surface of the multi-LED over-optic in a direction away from the substrate, and wherein the open ends of two or more of the cavities are in fluid communication via an internal volume between the multi-LED over-optic and substrate.
