Abstract

A light assembly to ground electronic elements, including a platform that supports a front part of the electronic elements; a housing that supports the electronic elements and the platform, the housing having an anchor that protrudes from the housing to support the platform, a plurality of ridges that protrudes from the housing to support a back part of the electronic elements, a back and a front reflective layers that cover the plurality of ridges and the anchor; and a connector that provides electrical connections between each electronic elements. The front and back reflective layers provide grounding for the electronic elements via the plurality of ridges and the anchor, the connector provides electrical connections between the electronic elements and the back reflective layer, and the platform support provides retaining of the electrical connections provided by the connector.

First claim

What is claimed is:

1. A light assembly to ground electronic elements, comprising:
a platform that provides support to a front part of the electronic elements;
a housing that provides support to the electronic elements and to the platform, the housing including:
an anchor that protrudes from the housing to support the platform, the anchor including
a seat that protrudes from the housing, and
a boss that protrudes from the seat,

a plurality of ridges that protrudes from the housing to support a back part of the electronic elements,
a back reflective layer that covers the anchor to reflect light, and
a front reflective layer connected to the back reflective layer that covers the plurality of ridges to reflect light; and

a connector that provides electrical connections between each electronic elements of the electronic elements,
wherein the front reflective layer further provides grounding for the electronic elements via the plurality of ridges,
wherein the back reflective layer further provides grounding for the electronic elements via the anchor,
wherein the connector further provides electrical connections between the electronic elements and the back reflective layer,
wherein the platform further provides maintaining of the electrical connections provided by the connector, and
wherein the seat further includes a crash ring that enhances a contact between the connector and the conductive layer.

2. The light assembly of claim 1 , wherein the crash ring includes an annulus that surrounds the boss and radial elements that radially extend through the annulus to enhance the contact.

3. The light assembly of claim 2 , wherein the annulus and the radial elements have heights between 0.1 mm and 1 mm.

4. The light assembly of claim 1 , wherein the seat further includes reinforcement legs placed radially around the seat that provides support for the seat.

5. A light assembly to ground electronic elements, comprising:
a platform that provides support to a front part of the electronic elements;
a housing that provides support to the electronic elements and to the platform, the housing including:
an anchor that protrudes from the housing to support the platform, the anchor including
a seat that protrudes from the housing, and
a boss that protrudes from the seat,

a plurality of ridges that protrudes from the housing to support a back part of the electronic elements,
a back reflective layer that covers the anchor to reflect light, and
a front reflective layer connected to the back reflective layer that covers the plurality of ridges to reflect light; and

a connector that provides electrical connections between each electronic elements of the electronic elements,
wherein the front reflective layer further provides grounding for the electronic elements via the plurality of ridges,
wherein the back reflective layer further provides grounding for the electronic elements via the anchor,
wherein the connector further provides electrical connections between the electronic elements and the back reflective layer,
wherein the platform further provides maintaining of the electrical connections provided by the connector, and
wherein the platform further includes
a bezel with an opening and
a fastening device to be inserted through the opening and threaded into a hole of the boss to fasten the platform on the anchor.

6. The light assembly of claim 5 , wherein the platform further includes a seal.

7. The light assembly of claim 5 , wherein the connector includes
a terminal that goes through the boss and contacts the seat,
plugs inserted onto the electronic elements, and
electrical wires that electrically connects the terminal and the plugs.

8. The light assembly of claim 7 , wherein the electrical wires includes ground wires that connect ground ports of the electronic elements to the terminal.

9. The light assembly of claim 8 , wherein the bezel presses the terminal against the seat via the fastening device.

10. The light assembly of claim 7 , wherein the boss has cylindrical shape and the terminal has an opening that matches the cylindrical shape.

11. The light assembly of claim 5 , wherein the seat further includes reinforcement legs placed radially around the seat that provides support for the seat.

12. A light assembly to ground electronic elements, comprising:
a platform that provides support to a front part of the electronic elements;
a housing that provides support to the electronic elements and to the platform, the housing including:
an anchor that protrudes from the housing to support the platform,
a plurality of ridges that protrudes from the housing to support a back part of the electronic elements, and
a reflective layer that covers the anchor and the plurality of ridges to reflect light; and

a connector that provides electrical connections between each electronic elements of the electronic elements,
wherein the reflective layer further provides grounding for the electronic elements,
wherein the connector further provides electrical connections between the electronic elements and the reflective layer,
wherein the platform further provides maintaining of the electrical connections provided by the connector,
wherein the anchor includes
a seat that protrudes from the housing, and
a boss that protrudes from the seat, and

wherein the platform further includes
a bezel with an opening and
a fastening device to be inserted through the opening and into a hole of the boss to fasten the platform on the anchor.

13. The light assembly of claim 12 , wherein the reflective layer is made of aluminum to reflect light and conduct electricity.

14. The light assembly of claim 13 , wherein the reflective layer further includes cut out sections to prevent electrical connections with lighting elements that are not supported by electronic elements.

15. The light assembly of claim 12 , wherein the connector includes
a terminal that goes through the boss and contacts the seat,
plugs inserted onto the electronic elements, and
electrical wires that electrically connects the terminal and the plugs.

16. The light assembly of claim 15 , wherein the electrical wires includes ground wires that connect ground ports of the electronic elements to the terminal.

17. The light assembly of claim 16 , wherein the bezel presses the terminal against the seat via the fastening device.
