Method of making a light-emitting-diode lamp tube

摘要

An automatic production method of making a light-emitting-diode lamp tube is disclosed. The method includes providing a circuit board in a shape of a long strip, printing a bonding layer, mounting electronic inserts, heating up the circuit board, assembling a heat dissipation seat, assembling a translucent cover and assembling an end cap, thereby accomplishing the lamp tube. By the abovementioned steps, the light-emitting-diode lamp tube can be produced automatically, the manufacturing process can be simplified to reduce the labor cost, and the yield factor can be improved considerably.

1. A method of making a light-emitting-diode lamp tube, comprising following sequential steps orderly:
a step (A) for providing a circuit board in a shape of a long strip, wherein the circuit board is provided with an outbound circuit and an inbound circuit; a step (B) for printing a bonding layer on a surface of the outbound circuit and the inbound circuit of the circuit board; a step (C) for mounting electronic inserts, with that a connecting seat is disposed on the outbound circuit of the circuit board where the bonding layer is provided, and light emitting diodes are disposed on the inbound circuit of the circuit board where the bonding layer is provided, wherein the connecting seat is disposed at an end side of the circuit board; a step (D) for heating up the circuit board to melt down the bonding layer, enabling the connecting seat and the light emitting diodes to be fixed on the circuit board; a step (E) for providing a heat dissipation seat which is in a shape of a long strip and is provided with a straight fixing surface; a step (F) for conducting a first assembling step to assemble and fix the circuit board that has been loaded with the light emitting diodes in the step (D) on the straight fixing surface of the heat dissipation seat; after the step (F), a step (G) for providing a translucent cover which is a long strip of an arc-shaped unit; a step (H) for conducting a second assembling step to assemble and fix the translucent cover on the heat dissipation seat that has been completed in the step (F), and to shield the circuit board; after the step (H), a step (I) for providing an end cap which is a round body and is provided with a conductive terminal; and a step (J) for conducting a third assembling step to assemble and fix the end caps on two end sides of the semi-finished product that has been completed in the step (H), and to connect the conductive terminal with the connecting seat, thereby accomplishing the lamp tube.
