Abstract
A method of manufacturing a lamp comprising forming a first sheet segment (48) into a first shell portion (110) after forming a first electrically conductive trace (70) on the first sheet segment (48) and after placing a first plurality of LEDs (90) on the first sheet segment (48); forming a second sheet segment (50) into a second shell portion (120) after forming a second electrically conductive trace (80) on the second plastic segment (50) and after placing a second plurality of LEDs (90) on the second sheet segment (50); and joining the first shell portion (110) and the second shell portion (120) into a bulb enclosure (40) defining an interior region (42) therein. The first and second sheet segments (48, 50) are preferably thermoformed and may be connected by a web (60).
