Abstract:
There is herein described a method for forming a circuit board comprising: (a) obtaining a substrate of a first formable polymer material, the substrate having at least one electrical conductor on a surface; (b) laminating a coverlay of a second formable polymer material to the substrate to form a flexible circuit board wherein the at least one electrical conductor is disposed between the coverlay and the substrate, the coverlay having a plurality of holes exposing at least a portion of the at least one electrical conductor; (c) electrically connecting light emitting diodes (LEDs) to exposed portions of the at least one electrical conductor; (d) heating the circuit board while applying a force to cause the circuit board to bend and adopt a shape having arcuate cross section; (e) cooling the circuit board until the shape becomes fixed whereby a thermoformed circuit board having an arcuate cross section is formed.
Abstract:
An edge assembly (108, 108') comprising at least a first edge component (110A, HOB, 110), flexible substrate (102) and a compression retainer component (118) attaching the first edge component (110A, HOB, 110) to the flexible substrate (102). The first edge component (HOA, HOB, 110) includes at least one conductor (112A, 112B, 112) to mate with one or more conductors (104) on a surface of a flexible substrate (102) after the first edge component (HOA, HOB, 110) is affixed to an edge of the flexible substrate (102) by the compression retainer component (118). The edge assembly (108, 108') may also comprises a second edge component (116), wherein the flexible substrate (102) may be compressed between the first and second edge components (106) and held in place by the compression retainer component (118). The first edge component (HOA, HOB, 110) further comprises an extension (114), including the at least one conductor (112A, 112B, 112), that is used to convey power from a power source (404) to the flexible substrate (102). The extension (114) is accessible from outside the flexible substrate (102) via a port (124) in the compression retainer component (118).
Abstract:
There is herein described a lamp (100) for providing white light com¬ prising a plurality of light sources (110) positioned on a substrate (120). Each of said light sources comprises a blue light emitting diode (140) (LED) and a dome (160) that substantially covers said LED. A first portion of said blue light from said LEDs is transmitted through said domes and a second portion of said blue light is converted into a red light by a first phosphor (161) contained in said domes. A cover (180) is disposed over all of said light sources that transmits at least a portion of said red and blue light emitted by said light sources. The cover contains a second phosphor (162) that emits a yellow light in response to said blue light. The red, blue and yellow light combining to form the white light and the white light having a color rendering in¬ dex (CRI) of at least about 80.
Abstract:
A method of manufacturing a curved component of a lamp or luminaire comprising forming a sheet segment into a curved portion after forming an electrically conductive trace on the sheet segment and after placing a plurality of LEDs on the sheet segment is described. A luminaire provided by the method of manufacturing is also described herein.
Abstract:
There is described an edge assembly for attaching to flexible substrates. An example assembly may comprise at least a first edge component and a compression retainer component. The first edge component may include at least one conductor to mate with one or more conductors on a surface of a flexible substrate after the first edge component is affixed to an edge of the flexible substrate by the compression retainer component. The edge assembly may also comprise a second edge component, wherein the flexible substrate may be compressed between the first and second edge components and held in place by the compression retainer component. The first edge component may further comprise an extension, including the at least one conductor, that may be used to convey power from a power source to the flexible substrate. The extension is accessible from outside the flexible substrate via a port in the compression retainer component.
