Embodiment Construction

[0018] In the manufacture and assembly of lighting systems having light emitting diodes (LEDs), LEDs and / or other optical components such as optical lenses and / or reflectors are often mounted on a substrate such as a printed wiring assembly (board). For example, PCT Application Publication No. WO 2010 / 027823 (which is incorporated by reference in this application as if fully set forth herein) discloses an LED lighting system that mounts multiple LEDs directly to a chassis. Various installation methods are disclosed herein such as, for example, the use of spring pushed rivets. However, the use of heat riveting may provide different advantages over the methods of installation disclosed herein.

[0019] In assemblies containing LEDs mounted on a submount and optical components such as lenses, magnifiers, covers, filters, diffusers, and / or reflectors, the optical performance of the LEDs depends on the reproducible dimensional consistency of the optical components sex. Variations...

Abstract

A method and system for fastening an optical component having one or more thermoplastic stakes extending therefrom to a substrate is shown. The method and system include providing and inserting the thermoplastic stakes through openings in the substrate. An elastomeric compensator, such as a sheet, a washer, an o-ring, or other gasket not like piece, is then disposed around one or more of the thermoplastic stakes. The thermoplastic stakes are then heated and molded to form rivet-like heads and pressure is applied to compress the elastomeric compensators between the rivet-like heads and the substrate to pull the optical component against the substrate.

Description

[0001] Cross references to related applications [0002] This patent application claims priority from US Provisional Patent Application No. 61 / 331139, filed May 4, 2010, the entire disclosure of which is incorporated by reference for any purpose. technical field [0003] The present invention relates generally to systems and methods for mounting components to substrates using thermoplastic stakes, and more particularly, but not limited to, to mounting optical lens and / or optical mirror components to substrates using thermoplastic stakes underlying systems and methods. Background technique [0004] In the assembly of many manufactured items, fastening together several components must be done quickly, efficiently, and under varying conditions. Various methods have been used to fasten these components together. These methods include fastening with adhesives, metal dust, bolts, rivets, or riveting. Riveting is the process of joining two elements by creating an interference fi...
