Systems and Methods for Lighting Fixtures

Abstract

Examples of the present disclosure are related to systems and methods for lighting fixtures. More particularly, embodiments disclose lighting fixtures utilizing metal core PCB (MCPCB) for thermal, mechanical, and/or optical controls.

What is claimed is: 
     
         1 . A light fixture, comprising:
 a plurality of light bars, wherein each light bar comprises:
 a substrate having at least one bend extending along a longitudinal axis of the light bar from a first end to a second end; and 
 a plurality of light sources directly embedded on the substrate; 
   a first rail connected to the first end of each of the plurality of light bars; and   a second rail connected to the second end of each of the plurality of light bars.   
     
     
         2 . The light fixture of  claim 1 , wherein the substrate comprises a metal core printed circuit board. 
     
     
         3 . The light fixture of  claim 1 , wherein the at least one bend is configured to direct heat generated by the plurality of light sources around a distal end of the least one bend and above the light bar. 
     
     
         4 . The light fixture of  claim 1 , wherein the at least one bend is configured to reflect light generated by the plurality of light sources to an area below the light bar. 
     
     
         5 . The light fixture of  claim 1 , wherein the substrate further comprises:
 an upper surface, wherein the plurality of light sources is directly embedded on the upper surface; and   two bends, each bend located on either side of the upper surface.   
     
     
         6 . The light fixture of  claim 5 , wherein the substrate further comprises a flat and planar surface positioned on a distal end of each of the two bends, wherein the upper surface and the flat and planar surface are positioned in parallel to each other at different vertical offsets. 
     
     
         7 . The light fixture of  claim 6 , wherein the first rail is connected to the upper surface and the flat and planar surface of each light bar via coupling mechanisms. 
     
     
         8 . The light fixture of  claim 1 , wherein the first rail and the second rail each comprise a hollow channel, wherein each of the plurality of light bars may slide along a length of the first rail and second rail via the hollow channel. 
     
     
         9 . The light fixture of  claim 1 , wherein the first rail further comprises electrical wiring that provides an electrical connection to each of the plurality of light bars. 
     
     
         10 . The light fixture of  claim 1 , wherein the first rail and the second rail are orthogonal to the plurality of light bars. 
     
     
         11 . A lighting system, comprising:
 a first light fixture according to  claim 1 ;   a second light fixture according to  claim 1 ;   a first hinge that connects the first rail of the first light fixture to the first rail of the second light fixture; and   a second hinge that connects the second rail of the first light fixture to the second rail of the second light fixture.   
     
     
         12 . The lighting system of  claim 11 , further comprising:
 a power supply that provides power to the first light fixture and the second light fixture.   
     
     
         13 . The lighting system of  claim 12 , wherein the power supply provides power to the light bars in the first light fixture and the second light fixture via electrical wiring in the first rail of the first light fixture and the first rail of the second light fixture. 
     
     
         14 . The lighting system of  claim 11 , wherein in a use mode the first hinge and the second hinge are extended such that the first light fixture is positioned in a same plane as the second light fixture. 
     
     
         15 . The lighting system of  claim 11 , wherein in a transportation mode the first hinge and the second hinge are folded such that the first light fixture is positioned adjacent and parallel to the second light fixture. 
     
     
         16 . The lighting system of  claim 11 , wherein the first light fixture comprises a first number of light bars and the second light fixture comprises a second number of light bars different from the first number.
