The Development Process On LED Light Lamps
LED light bulbs are built around solid-state semiconductor gadgets, so the production process most closely is identical to that used to make electronic products like Computer mother boards.
Let's consider the manufacturing steps for a typical LED light bulb meant to replace a standard incandescent bulb having an Edison Screw. You will find it is a very unique process from the highly computerized processes used to manufacture our common incandescent bulbs. And, regardless of what you might imagine, people are still very much a necessary part of manufacturing process, and not for examination and Quality Assurance only.
Once the more sheets of LED circuit boards have gone through a solder reflow oven (a hot air furnace that melts the solder paste), these are broken up into separate small circuit boards and power wires manually soldered on.
The small power supply housed in the body of the light bulb goes through a similar process, or can be delivered complete from an alternate factory. In any event, the manufacturing phases are the same; first the PCB passes through SMT lines, then it would go to a manual dual in-line package (DIP) setup line where a long row of factory workers add one component at a time. DIP refers to the two parallel rows of wires projecting from the edges of the package. DIP substances include all integral chips and chip sockets.
While LED lights burn several times longer than incandescent or CFLs and need less than half the power, they need some form of passive heatsink keep the high-power LEDs from overheating. The LED circuit board, which is made from 1.6-2mm thick light weight aluminum, will carry out the heat from the dozen or so LED components to the metallic heatsink frame and thus keep temperatures under control. Aluminum-backed PCBs are usually called "metal core printed circuit boards," and though made of a conductive material the white coating is electrically isolating. The aluminum PCB is actually screwed in place within the heatsink which shapes the lower half of the LED light bulb.
Shell setting up consists of safety locking the shell in place with screws. A plastic shell covers the power supply and hooks up with the metal heatsink and LED circuit board. Air flow holes are included to allow hot air to escape. Wiring assembly for plug socket requires soldering wires to the bulb plug. Then shell is joined.
Next, the final product LED , is sent to burn-in local testing and quality control. The burn-in test usually lasts for 30 minutes. The completed LED light bulb is then powered up to see if it is working properly and burned in for 30 minutes. There is also a high-voltage discharging and failure test and wattage and energy factor test. Samples from the production run are tried for high-voltage leakages, power consumption, and power factor (efficiency).
After a final check to make sure all the different aspects of the LED light are tightly held, then it is arranged into individual boxes, and bulbs are transported.
So, if you have wondered why LED light bulbs are so highly-priced today, this explanation of how they are manufactured and how that compares to the manufacture of traditional light bulbs should help. However, it also shows why the cost will drop pretty drastically over the next several years. Just as the cost of manufacturing other semiconductor-based merchandise has fallen considerably due to standardization, automation and other key steps along the manufacturing learning curve, identical inexorable forces will drive down the prices of LED light bulb production.
