An illuminator (10) includes a circuit board (12) having a planar board portion (44) and a board portion non-planar to said planar board portion (44). The board portion non-planar to said planar board portion (44) defines one of a board interface (14) and a reflector (50). A method for manufacturing an illuminator (10) is also disclosed.
Abstract:
The present invention comprises a printed circuit (30) having a three-dimensional surface capable of conforming to a contoured surface of a vehicle trim panel. Printed circuit (30) comprises a plurality of electrical conductors (34) and connectors (36) secured to a polymeric substrate (32). A convoluted region (58) of the printed circuit permits formation of the three-dimensional surface (60) in the printed circuit (30). The present invention further comprises a method of producing three-dimensional surface (60) and the printed circuit (30) by either thermoforming the printed circuit (30) or mechanically stretching the printed circuit (30) to produce the three-dimensional surface (60).
Abstract:
An apparatus and method for forming a conical or domed ring light (20) having a plurality of light sources (36) arranged at a desired angle with respect to the optical axis. The light sources are installed at desired locations on a first surface of the flexible circuit board (22) and are each coupled to a common electrical connector (37), having one or a plurality of power sources, to facilitate supplying electrical power to each one of the light sources. The circuit board is then folded into a conical or domed configuration (39), with the light sources facing inward, and each abutted end and lateral surfaces of the folded circuit board is suitably secured or fastened to one another to permanently retain the flexible circuit board in its folded state.
Abstract:
A highly accurate circuit pattern (14) in intimate contiguous relationship with a curved plastic body (12) and a method of manufacture thereof. In accordance with the present invention, circuit pattern (14) is detachably fixed to a flexible substrate (16) and is placed into a mold (20). A molding compound (22) is then forced into the mold pressing the circuit against the mold wall and filling all of the mold voids. The molded product is thereafter removed from the mold. The flexible substrate (16), on which the metallic circuit is printed, is removed from the molded product leaving the metallic circuit pattern (14) imbedded into the molded product.
Abstract:
An electronic module is provided for a power tool having an electric motor. The electronic module includes a printed circuit board (PCB) being substantially disc-shaped; power switches mounted on the PCB forming an inverter bridge circuit for driving the electric motor; a controller mounted on the PCB and configured to control a switching operation of the power switches; positional sensors mounted on the PCB substantially equidistantly from a center of the PCB within the control portion and in communication with the controller to provide positional signals related to a rotational position of the electric motor to the controller; and a module housing arranged to receive the PCB therein. The module housing includes a planar portion in parallel to the PCB and openings disposed in the planar portion angularly around a center of the module housing to receive the positional sensors therein.
Abstract:
A light emitting diode (LED) module includes a base that is conductive and is selectively covered with an insulative layer. The base can include a connecting flange and a light emitting region. Traces are provided on the insulative coating and can be used to connect LEDs positioned on the light emitting region to pads on the connecting flange. The connecting flange can be offset in angle and/or position from the base and can be configured to provide a contact shape suitable to mate with a connector in a polarized manner. The base can be shaped so as to provide the desired functionality.
