Definitions

the present invention relates to a method of assembling a light bulb, and more particularly to a method of assembling an airtight LED light bulb.
a conventional LED light bulb has a heat-sink housing 60, an LED device, a bulb envelope 70, a stem device and a cap 80.
the heat-sink housing 60 is made of metal, has a top edge and is used to dissipate heat generated from the LED device.
the bulb envelope 70 is securely combined with the top edge of the heat-sink housing 60.
the LED device is mounted in the heat-sink housing 60 and the bulb envelope 70.
the stem device is securely connected with the LED device and is detachably mounted in the heat-sink housing 60.
the cap 80 is mounted securely around the stem device.
the conventional LED light bulb has following drawbacks.
the present invention tends to provide a method of assembling an airtight LED light bulb to obviate the aforementioned problems.
the main objective of the invention is to provide a method of assembling an airtight LED light bulb.
a method of assembling an airtight LED light bulb has steps of: connecting a stem device with an LED device, drying the LED device, connecting a stem device with a bulb envelope, extracting air in the bulb envelope via a pipe, filling the bulb envelope with nitrogen or inert gas via the pipe, sealing an opening of the pipe which is located outside the bulb envelope to make the bulb envelope completely airtight and connecting a cap with the bulb envelope. Because the bulb envelope is airtight, the moisture in the environment can not damage the LED device and the steps of extracting air in the bulb envelope via the pipe and filling the bulb envelope with nitrogen or inert gas via the pipe are feasible. Consequently, the LED device will not easily be oxidized or dampened, so the lifespan of the LED light bulb can be prolonged.
a method of assembling an airtight LED light bulb in accordance with the present invention comprises following steps:
the wires 12 are respectively mounted though the base 11 and each wire 12 has a supporting end 121 and a connecting end 122.
the supporting ends 121 of the wires 12 are mounted outside and securely on the first end of the base 11 and are made of steel.
the connecting ends 122 of the wires 12 are adjacent to the flange 111.
the pipe 13 is made of glass, is securely mounted in and protrudes out from the base 11 and has two opposite openings.
the LED device 20 is mounted securely on and electrically connected with the supporting ends 121 of the wires 12 and has at least one LED. Because the supporting ends 121 are made of steel, the wires 12 can support the LED device 20 stably. Drying the LED device 20:
time of drying the LED device 20 ranges from 10 to 15 minutes and the temperature of drying the LED device 20 ranges from 120 to 125 degree Celsius.
the bulb envelope 30 is stood and the torch F is tilted downwards slightly.
the flame F1 aims at the flange 111 (assuming the flame F1 is straight jetted out along a line which the torch F is located).
a flame angle ⁇ is defined as an angle between the flame F1 and a horizontal line at which the flange 111 is located.
the flame angle ⁇ ranges from 5°to 15°. Because the flame F1 is tilted downwards, a temperature distribution of the bulb envelope 30 and the stem device 10 is changed to prevent the LED device 20 from being burnt out.
the bulb envelope 30 is stood upside down and the torch F is mounted latitudinally, and the flame F1 aims at the flange 111.
the flame F1 melts the flange 111
air in the bulb envelope 30 is also heated up. Accordingly, air in the upside-down bulb envelope 30 will not convect to flow toward and damage the LED device 20.
Air in bulb envelope 30 is extracted via the pipe 13.
