What is DOB Driver Solution?

The driving power is the "heart" of LED lighting. The features of LED lighting fixtures - energy conservation, intelligence, and long service life - are basically achieved by relying on a good driving power. 

 LED drivers account for about 20% of the cost of lighting fixtures, which not only affects cost but also affects lighting efficiency and determines the lifespan of LED lights. Here, the author will introduce one LED driving method – DOB.

DOB means driver on board or driverless. Yet DOB solution does not mean no driver. It is improved and simplified on the basis of traditional driving solution. Cut some components such as electrolytic capacitors and transformers with relatively large volume, simplify the circuit design and device, reduce the volume, so that the smaller parts and LED light source packaging combined in an integrated way to package into a whole AC-LED on the PCB.

The main advantages of DOB are as follows:

1.    Thinner and lighter, save the shipping costs.

2.    Full-auto SMT, save the labor costs, reduce the rate of defective rates.

3.    IC chips and LEDs are on the same PCB, prolong the LEDs lifespan.

4.    Almost without electrolytic capacitor components, more stable.

5.    Uniform distribution of lamp beads, more equable shine.

All in all, in LED field, the trend of development is simpler, compact and economic. DOB tech market’s growth over 200% every year. With increasingly improvement of this technology, LED DOB tech light will be keep pace with traditional led light with driver in the future.
