Abstract

Retention members for securing LED boards to substrates while permitting light from the LEDs to be emitted unobstructed. The present retention members may be in the form of clips that are designed to span an LED board and attach to a substrate so as to trap the LED board between a retention member and the substrate. The retention members described herein may include one or more retention features that may interface with a corresponding mounting feature formed on the substrate to secure the retention member and thus the LED board to a substrate.

First claim

What is claimed is:

1. A retention member for securing a light emitting diode (LED) board to a substrate, wherein the LED board comprises a width and at least one row of LEDs, and wherein the retention member comprises a width greater than the width of the LED board and:
a. a retention member body configured to extend across the width of the LED board between LEDs within the at least one row of LEDs, wherein the retention member body comprises a recess formed on an underside of the retention member body configured to receive the LED board;
b. a first retention wing integral with the retention member body and comprising a first protrusion configured to engage a first aperture defined by the substrate; and
c. a second retention wing integral with the retention member body and comprising a second protrusion configured to engage a second aperture defined by the substrates wherein:
at least a portion of a bottom surface of each of the first retention wing and the second retention wing is positioned against a top surface of the substrate;
each of the first protrusion and the second protrusion is configured to extend through a respective one of the first aperture and the second aperture such that each protrusion contacts a bottom surface of the substrate.

2. The retention member of claim 1 , wherein:
the retention member body defines at least one aperture configured to receive at least one LED within the at least one row of LEDs.

3. The retention member of claim 1 , wherein:
the retention member is configured to snap fit onto the substrate so as to trap the LED board between the retention member and the substrate.

4. The retention member of claim 1 , wherein:
the retention member body extends in a plane; and
the first retention wing and the second retention wing each extends in a plane offset from the plane of the retention member body.

5. The retention member of claim 1 , wherein:
the recess comprises a height that is substantially the same as a height of the LED board.

6. The retention member of claim 5 , wherein:
the recess comprises a width that is substantially the same as a width of the LED board.

7. The retention member of claim 1 , wherein:
the retention member comprises an electrically non-conductive material.

8. The retention member of claim 1 , wherein:
the retention member body has a thickness that is less than or equal to a height of at least one LED within the at least one row of LEDs.

9. The system of claim 8 , wherein:
the at least one row of LEDs comprises a first row of LEDs and a second row of LEDs;
LEDs within the first row of LEDs are staggered relative to LEDs within the second row of LEDs; and
the retention member body defines an aperture, wherein at least one LED of the first row of LEDS is positioned within the aperture and wherein the retention member body extends between adjacent LEDs within the second row of LEDs.

10. The system of claim 8 , wherein:
the at least one row of LEDs comprises a first row of LEDs and a second row of LEDs;
LEDs within the first row of LEDs are in a symmetric and parallel arrangement relative to LEDs within the second row of LEDs;
the retention member body defines a first aperture configured to receive an LED of the first row of LEDS; and
the retention member body defines a second aperture configured to receive an LED of the second row of LEDS.

11. The system of claim 10 , wherein:
the at least one row of LEDs further comprises a third row of LEDs interposed between, and staggered relative to, the first and second rows of LEDs; and
the retention member body extends between adjacent LEDs within the third row of LEDs.

12. The system of claim 8 , wherein:
the recess comprises a height that is substantially the same as a height of the LED board.

13. The system of claim 12 , wherein:
the recess comprises a width that is substantially the same as a width of the LED board.

14. The system for securing a light emitting diode (LED) board to a substrate of claim 8 , wherein:
the retention member comprises an electrically non-conductive material.

15. A system for securing a light emitting diode (LED) board to a substrate, the system comprising:
a substrate defining a plurality of apertures;
an LED board positioned on the substrate and comprising a plurality of LEDs provided in at least one LED row along a length of the LED board; and
at least one retention member comprising:
a retention member body extending across the width of the LED board and between LEDs within the at least one row of LEDs, the retention member body comprising a recess formed on an underside of the retention member body, wherein the LED board is positioned at least partially within the recess;
a first retention wing integral with the retention member body and comprising a first protrusion engaged with one of the plurality of apertures on the substrate such that the first protrusion contacts a bottom surface of the substrate; and
a second retention wing integral with the retention member body and comprising a second protrusion engaged with another of the plurality of apertures on the substrate such that the second protrusion contacts the bottom surface of the substrate,

wherein at least a portion of a bottom surface of each of the first retention wing and the second retention wing is positioned against a top surface of the substrate.

16. A method a securing an LED board to a substrate, wherein the LED board comprises at least one row of LEDs and the substrate comprises a plurality of apertures, the method comprising:
positioning the LED board on the substrate;
positioning a retention member across the LED board such that the LED board is positioned between a body of the retention member and the substrate and such that the body of the retention member extends between LEDs within the at least one row of LEDs, the retention member further comprising a first retention wing integral with the body and a second retention wing integral with the body, wherein at least a portion of a bottom surface of each of the first retention wing and the second retention wing is positioned against a top surface of the substrate;
securing a first protrusion provided on the first retention wing with one of the plurality of apertures on the substrate such that the first protrusion extends through the one of the plurality of apertures and contacts a bottom surface of the substrate; and
securing a second protrusion provided on the second retention wing with another one of the plurality of apertures on the substrate such that the second protrusion extends through the another of the plurality of apertures and contacts the bottom surface of the substrate.

17. The method of claim 16 , wherein:
the at least one row of LEDs comprises a first row of LEDs and a second row of LEDs;
LEDs within the first row of LEDs are staggered relative to LEDs within the second row of LEDs;
the body of the retention member defines an aperture; and
positioning the retention member across the LED board further comprises positioning the body of the retention member on the LED board such that at least one LED within the first row of LEDs is positioned within the aperture.
