High mount stop lamp with printed circuit board
First Claim
1. A method of manufacturing an automotive lamp comprising a lens, a printed circuit board having at least one of LED, and a lamp housing, the method comprising the steps of:
- a. fixing the lens to the printed circuit board to form a PCB subassembly, the fixed relationship between the lens and the printed circuit board thereby securing a proper alignment between the lens and the at least one LED on the printed circuit board; and
b. fixing the PCB subassembly to the lamp housing;
c. wherein the lens is fixed to the printed circuit board by first contacting the lens and the printed circuit board such that a plurality of stakes, mounted on the lens, extend through a plurality of associated holes in the circuit board, and then melting the plurality of stakes extending through the plurality of holes; and
d. wherein the PCB subassembly is fixed to the lamp housing by first contacting the PCB subassembly and the lamp housing such that a plurality of stakes, mounted on the housing, extend through a plurality of associated holes in the circuit board, and then melting the plurality of stakes extending through the plurality of holes.

Abstract
A thin automobile lamp assembly is manufactured by first fixing an elongated printed circuit board (PCB) having a plurality of LEDs to an elongated inner lens before the inner lens and PCB are joined to any other parts. The inner lens is fixed to the PCB by contacting the inner lens and the PCB such that a plurality of stakes on the inner lens extend through a plurality of associated holes on the PCB. The stakes extending through the holes are then melted by a process such as heat staking to fix the PCB to the inner lens. The fixed relationship between the inner lens and the PCB board secures a proper alignment between the lens and the plurality of LEDs on the PCB. Next, the PCB and lens subassembly is joined to a lamp housing, and the entire assembly is secured to an automobile.
