How LED bulb are made

So, if you have wondered why LED light bulbs are so expensive today, How LED Light Bulbs Are Made article gives explanation of how they are manufactured and how that compares to the manufacture of traditional light bulbs should help. However, it also reveals why the cost will fall pretty dramatically over the next few years. Just as the cost of manufacturing other semiconductor-based products has fallen dramatically due to standardization, automation and other key steps along the manufacturing learning curve, the same inexorable forces will drive down the costs of LED light bulb production.
