How to Face the Design Challenge of LED Dimmable Driver?

With the increased emphasis on energy problems, many countries use LED chips to replace traditional lighting source, which has become an obvious trend. LED illumination lamps don’t need to change its basic components, it can be used directly with a good business prospect. Form many traditional lamps, MR16 is a representative product. It is widely used in markets, homes, hospitals, etc. It is well known that MR16 has small dimension and needs use transformer with dimmer to dim the light, which gives design challenge for LED dimmable driver.

First, let’s see a representative MR16 dimming system as below.

High voltage 220V transforms low voltage 12V via the transformer, which gives power to LED dimmable driver. We must fully consider the technologies of LED dimmable driver: dimming compatibility, dimension, cost, etc.
