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 optical controls.

First claim

What is claimed is:

1. A system for optically controlling a light pattern comprising
a substrate with a substrate length;
at least one light source positioned on a center panel of the substrate, wherein the at least one light source is configured to emit light on an area of distribution;
first bends extending along a longitudinal axis of the substrate on both sides of the at least one light source, the first bends having a first angle;
first panels on the substrate having first ends positioned adjacent to the first bends, the first panels having a first length and a first height, wherein a first distance from the first bends to second ends of the first panels determine the area of distribution of light emitted from the at least one light source, the first height being a vertical distances from the substrate to the seconds ends, wherein the first height impacts a mechanical strength of the system, wherein the first angle and the first height are modified based in part on the substrate length.

2. The system of claim 1 , further comprising:
second bends extending along a longitudinal axis of the substrate on the second ends of the first panels, the second bends having a second angle, the second bends being positioned on the second ends of the first panels;
second panels having first ends positioned adjacent to the second bends, the second panels having a second length, wherein a second distance from the first bends to second ends of the second panels determine the area of distribution of light emitted from the at least one light source.

3. The system of claim 2 , wherein when the first length is greater than the second length then the first panel has a larger impact on the distribution of light emitted from the at least one light source than the second panel, and when the first angle is greater than the second angle then the first bend has a larger impact on the distribution of light emitted from the at least one light source than the second bend.

4. The system of claim 1 , wherein the substrate is tinned.

5. The system of claim 1 , wherein reflectors are adhered to the substrate.

6. The system of claim 1 , wherein the at least one light sources are symmetrically positioned with respect to the first panels to create a symmetrical light distribution pattern.

7. The system of claim 1 , wherein the at least one light sources are asymmetrically positioned with respect to the first panels to create an asymmetrical light distribution pattern.

8. The system of claim 1 , wherein a subtended angle from the first bends to second ends of the first panels determine a level of optical control of the system.

9. The system of claim 8 , wherein the level of optical control determines at least one of a light intensity, uniformity, spread, and pattern.

10. The system of claim 9 , wherein increasing the subtended angle increases the level of optical control.

11. A method for optically controlling a light pattern for a system, comprising:
positioning at least one light source positioned on a center panel of a substrate;
creating first bends that extend along a longitudinal axis of the substrate on both sides of the at least one light source, the first bends having a first angle;
determining an area of distribution of light emitted from the at least one light source;
determining a substrate length of the substrate;
forming first panels on the substrate when creating the bends, the first panels having first ends positioned adjacent to the first bends, the first panels having a first length and a first height, wherein a first distance from the first bends to second ends of the first panels, the first height being a vertical distances from the substrate to the seconds ends, wherein the first height impacts a mechanical strength of the system;
increasing the first length to increase an effect of the light emitted from the at least one light source on the area of distribution; and
modifying the first angle to change the first height based in part on the substrate length.

12. The method of claim 11 , further comprising:
forming second bends extending along a longitudinal axis of the substrate on the second ends of the first panels, the second bends having a second angle, the second bends being positioned on the second ends of the first panels;
forming second panels having first ends positioned adjacent to the second bends, the second panels having a second length, wherein a second distance from the first bends to second ends of the second panels determine the area of distribution of light emitted from the at least one light source.

13. The method of claim 11 , wherein when the first length is greater than the second length then the first panel has a larger impact on the distribution of light emitted from the at least one light source than the second panel, and when the first angle is greater than the second angle then the first bend has a larger impact on the distribution of light emitted from the at least one light source than the second bend.

14. The method of claim 11 , wherein the substrate is tinned.

15. The method of claim 11 , further comprising:
adhering reflectors to the substrate.

16. The method of claim 11 , wherein the at least one light sources are symmetrically positioned with respect to the first panels to create a symmetrical light distribution pattern.

17. The method of claim 11 , wherein the at least one light sources are asymmetrically positioned with respect to the first panels to create an asymmetrical light distribution pattern.

18. The method of claim 11 , further comprising:
determining a level of optical control or the system based on a subtended angle from the first bends to second ends of the first panels.

19. The method of claim 18 , wherein the level of optical control determines at least one of a light intensity, uniformity, spread, and pattern.

20. A system for optically controlling a light pattern
a substrate with a substrate length;
at least one light source positioned on the substrate, wherein the at least one light source is configured to emit light on an area of distribution;
first bends extending along a longitudinal axis of the substrate on both sides of the at least one light source, the first bends having a first angle;
first panels on the substrate having first ends positioned adjacent to the first bends, the first panels having a first length and a first height, wherein a first distance from the first bends to second ends of the first panels determine the area of distribution of light emitted from the at least one light source, the first height being a vertical distances from the substrate to the seconds ends, wherein the first height impacts a mechanical strength of the system.
