Optic panel, LED lighting system, and luminaire
First Claim
1. A luminaire, comprisinga housing;
- an LED lighting system carried by the housing; and
a driver to drive the LED lighting system from an electrical power source;
wherein the LED lighting system further comprises;
a light emitting diode;
a primary optic coupled to the light emitting diode to receive and transmit light from the light emitting diode; and
a secondary optic panel having a secondary optic that covers the primary optic to receive light transmitted from the primary optic and transmit the light, wherein the secondary optic panel comprises;
a base plate having a cutout, wherein the base plate fixes the secondary optic over the primary optic;
the secondary optic disposed in the cutout and coupled to the base plate, the secondary optic comprising a collector and a light pipe extending upwardly from the collector, wherein the light pipe has a distal end spaced from the collector, and light collected by the collector is focused outwardly by the light pipe; and
a plurality of supports, each support extending from the base plate to the light pipe, wherein the supports fix the secondary optic to the base plate;
wherein each support engages the light pipe at only a single contact point and a gap is disposed between the support and all other portions of the secondary optic.

Abstract
An optic panel, an LED lighting system including the optic panel, and a luminaire including the LED lighting system are described. The optic panel includes an optic disposed within a cut out of a base plate, and one or more supports fixedly couple the optic with the base plate. Each support preferably touches the optic at only a single location. In some aspects, the supports provide sufficient support to the optic such that the entire optic panel can be molded as a single, monolithic mass and the supports do not or only minimally interfere with the desired total internal reflection of the optics because of the minimal engagement with the supports and/or the placement of the engagement with the supports. The optic panel may be incorporated into the LED lighting system, for example, forming a secondary optics for the LED lighting system.

18. A method of manufacturing a luminaire, comprising:
-
assembling an LED lighting system; and fixing the LED lighting system and a driver to drive the LED lighting system within a housing; wherein assembling an LED lighting system comprises; fixing a light emitting diode with a primary optic, the primary optic covering the light emitting diode and configured such that the primary optic receives and transmits light from the light emitting diode; assembling a secondary optic panel comprising a secondary optic; and covering the primary optic with the secondary optic such that the secondary optic receives and transmits the light from the primary optic; wherein assembling the secondary optic panel comprises; cutting a cutout from a base plate; disposing in the cutout the secondary optic, the secondary optic comprising a collector and a light pipe extending upwardly from the collector, wherein the light pipe has a distal end spaced from the collector, and light collected by the collector is focused outwardly by the light pipe; and fixing the secondary optic to the base plate using a plurality of supports, each support extending from the base plate to the light pipe, wherein fixing the secondary optic to the base plate comprises engaging the light pipe with the support at only a single contact point such that a gap is disposed between the support and all other portions of the secondary optic. - View Dependent Claims (19, 20)
