Abstract

Systems and methods for mounting optics to an LED lighting module include a retainer engageable with the lighting module and a removable upper plate for securing the optics in the retainer.

Claims

1. A system for mounting optics to an LED lighting module comprising one or more LEDs connected thereto and circuitry for the one or more LEDs, the system comprising:

a retainer engageable with the lighting module and comprising at least one retention region configured to retain at least one optical element in a fixed configuration with respect to the at least one LEDs; and

a removable upper plate for securing the at least one optical element in the retainer without contacting the circuitry.

2. The system of claim 1, wherein the retainer is engageable to a heat sink of the LED lighting module, the heat sink being disposed below the one or more LEDs.

3. The system of claim 2, further comprising a thermally conductive material applied in a gap between the retainer and the heat sink for efficiently dissipating waste heat.

4. The system of claim 1, wherein the retainer comprises a plurality of retention collars each retainably accommodating a geometry of an individual optical element.

5. The system of claim 4, wherein the retention collar comprises a retention element protruding therefrom for retaining the optical element.

6. The system of claim 4, wherein an inner surface of the retention collar frictionally engages the optical element.

7. The system of claim 1, further comprising means for facilitating removable clamping of the upper plate to the retainer.

8. The system of claim 1, further comprising an adjustment element for adjusting a position of the optical element in the fixed configuration.

9. A method of mounting at least one optical element to an LED lighting module comprising a plurality of LEDs, the method comprising:

positioning the at least one optical element in a retainer at a desired position relative to at least one of the plurality of LEDs; and

removably securing the retainer to the lighting module such that the optical element is fixedly retained at the desired position without contact with any circuitry.

10. The method of claim 9, wherein the optical element is secured to the retainer by an upper plate engageable with the retainer.

11. The method of claim 9, wherein the optical element is retained in the retainer by an element protruding therefrom.

12. The method of claim 9, wherein an inner surface of the retention collar frictionally engages the optical element.

13. The method of claim 9, further comprising adjusting the optical elements in the retainer using an adjustment element.

14. The method of claim 9, wherein the retainer is removably secured by an upper plate.
