Abstract

Lighting systems having unique configurations are provided. For instance, the lighting system may include a light source, a thermal management system and driver electronics, each contained within a housing structure. The light source is configured to provide illumination visible through an opening in the housing structure. The thermal management system includes a plurality of synthetic jets. The synthetic jets are arranged within the lighting system such that they are secured at contact points.

First claim

What is claimed is:

1. A method of manufacturing a lighting system, the method comprising:
providing a housing structure configured to house a light source and a thermal management system therein, the thermal management system comprising a plurality of synthetic jet devices;
mounting the plurality of synthetic jet devices within the housing structure such that the plurality of synthetic jet devices are positioned to provide cooling to the light source, wherein mounting the plurality of synthetic jet devices further comprises:
providing a base bracket configured to hold each of the plurality of synthetic jet devices within the housing structure;
positioning the plurality of synthetic jet devices on the base bracket; and
coupling a bridge to the housing structure such that each of the plurality of synthetic jet devices is retained between the bridge and the base bracket, wherein positioning the plurality of synthetic jet devices on the base bracket comprises sliding the plurality of synthetic jet devices into a plurality of slots formed in the base bracket, such that each of the plurality of synthetic jet devices is positioned in a pair of slots.

2. The method of claim 1 wherein the base bracket and the bridge hold the plurality of synthetic jet devices within the housing structure in a point contact configuration comprising a plurality of contact points.

3. The method of claim 1 wherein sliding a synthetic jet device into a respective pair of slots formed in the base bracket holds the synthetic jet device at two contact points.

4. The method of claim 1 wherein providing the base bracket comprises providing the base bracket having the plurality of slots molded into the base bracket.

5. The method of claim 1 wherein providing the base bracket comprises providing a base bracket molded integrally into the housing structure.

6. A method of manufacturing a lighting system, the method comprising: providing a housing structure configured to house a light source and a thermal management system therein, the thermal management system comprising a plurality of synthetic jet devices;
mounting the plurality of synthetic jet devices within the housing structure such that the plurality of synthetic jet devices are positioned to provide cooling to the light source, wherein mounting the plurality of synthetic jet devices further comprises:
providing a base bracket configured to hold each of the plurality of synthetic jet devices within the housing structure;
positioning the plurality of synthetic let devices on the base bracket; and coupling a bridge to the housing structure such that each of the plurality of synthetic jet devices is retained between the bridge and the base bracket wherein coupling the bridge to the housing structure comprises snapping the bridge into a slot formed in the housing structure; wherein coupling the bridge to the housing structure comprises snapping the bridge into a slot formed in the housing structure.

7. The method of claim 1 further comprising positioning a light source within the housing structure so as to provide illumination visible through an opening in the housing structure.

8. The method of claim 7 further comprising positioning a heat sink adjacent a backside of the light source, the heat sink comprising a base portion and a plurality of fins extending from the base portion so as to provide a plurality of air gaps therebetween.

9. The method of claim 8 wherein positioning the plurality of synthetic jet devices on the base bracket comprises positioning the plurality of synthetic jet devices such that the plurality of synthetic jet devices are positioned to produce an air flow path through the respective air gaps between the plurality of fins.

10. The method of claim 8 wherein the base bracket and the bridge hold the plurality of synthetic jet devices within the housing structure such that the plurality of synthetic jet devices are mounted independent from the heat sink so as to not be in contact with the heat sink.

11. The method of claim 1 further comprising positioning the light source within the housing structure, the light source comprising a light emitting diode (LED) light source comprising a plurality of LEDs.

12. A lighting system comprising a light source configured to provide illumination visible through an opening in a housing structure and a thermal management system configured to cool the light source, wherein the lighting system is formed by:
providing a light source configured to provide illumination;
positioning the light source within a housing structure, the housing structure configured to house both the light source and a thermal management system therein, the thermal management system comprising a plurality of synthetic jet devices;
mounting the plurality of synthetic jet devices within the housing structure such that the plurality of synthetic jet devices are positioned to provide cooling to the light source, wherein mounting the plurality of synthetic jet devices further comprises:
providing a base bracket configured to hold each of the plurality of synthetic jet devices within the housing structure;
positioning the plurality of synthetic jet devices on the base bracket; and coupling a bridge to the housing structure such that each of the plurality; of synthetic jet devices is retained between the bridge and the base bracket;

wherein the lighting system is further formed by sliding the plurality of synthetic jet devices into a plurality of slots formed in the base bracket, such that each of the plurality of synthetic jet devices is positioned in a pair of slots so as to be held at two contact points.

13. The lighting system of claim 12 wherein the plurality of synthetic jet devices are retained between the base bracket and the bridge in a point contact configuration comprising a plurality of contact points.

14. A lighting system comprising a light source configured to provide illumination visible through an opening in a housing structure and a thermal management system configured to cool the light source, wherein the lighting system is formed by:
providing a light source configured to provide illumination;
positioning the light source within a housing structure, the housing structure configured to house both the light source and a thermal management system therein, the thermal management system comprising a plurality of synthetic let devices;
mounting the plurality of synthetic jet devices within the housing structure such that the plurality of synthetic jet devices are positioned to provide cooling to the light source, wherein mounting the plurality of synthetic jet devices further comprises:
providing a base bracket configured to hold each of the plurality of synthetic jet devices within the housing structure;
positioning the plurality of synthetic jet devices on the base bracket; and coupling a bridge to the housing structure such that each of the plurality of synthetic jet devices is retained between the bridge and the base bracket, wherein the lighting system is further formed by snapping the bridge into a slot formed in the housing structure, so as to coupe the bridge to the housing structure.

15. The lighting system of claim 12 wherein, in providing the light source, the lighting system is further formed by providing a light emitting diode (LED) light source comprising a plurality of LEDs, the LED light source configured to provide at least 1500 lumens.

16. The lighting system of claim 15 wherein the lighting system is further formed by positioning a heat sink adjacent a backside of the LED light source, the heat sink compri
