发明名称 Low-Profile Outdoor Lighting Module With Light Emitting Diodes
摘要 A low-profile lighting module with light-emitting diodes (LEDs) has a water-tight seal between a molded-plastic cover and a printed circuit board (PCB). A substrate with the LEDs fits up into an indentation in the lower surface of the PCB. Landing pads on the top of the substrate attach to contact pads in the indentation that are extensions of a conductor of the PCB which is electrically coupled through the landing pads to the LEDs. A lens with a curved optical portion surrounded by a flat lip fits into another indentation on the upper surface of the PCB. A highly reflective sheet is disposed between the planar lower surface of the lens and bottom of the indentation in the upper surface. A double-sided adhesive sheet is disposed under the inside surface of the molded-plastic cover and over both the upper surface of the PCB and the flat lip of the lens.

主权项 1. A device comprising: a light emitting diode (LED) die; a substrate with a top surface and a bottom surface, wherein the LED die is disposed on the top surface of the substrate; a landing pad disposed on the top surface of the substrate; a printed circuit board having a conductor, a lower surface, a lower indentation in the lower surface, an upper surface, and an upper indentation in the upper surface, wherein the substrate fits into the lower indentation such that the conductor is electrically coupled through the landing pad to the LED die, and wherein the lower surface of the printed circuit board and the bottom surface of the substrate are substantially coplanar; a highly reflective sheet; a lens with a planar lower surface and a lip, wherein the highly reflective sheet is disposed between the lower surface of the lens and the upper indentation; a double-sided adhesive sheet; and a cover of molded plastic with an inside surface, wherein the adhesive sheet is disposed under the inside surface of the cover and over both the upper surface of the printed circuit board and the lip of the lens.
