We’ve been hearing more and more recently about the idea of DOB solution LED lights, but in fact, this is not a brand new idea which has been proposed and used for several years. This technology has many forerunners in the industry like Seoul Semiconductor, Lynklabs, Texas Instruments, Exclara and Interlight, etc.

DOB means driver on board, but not means no driver. Actually it was improved and simplified by other technologies. 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 are as follows:

1. Ultrathin and ultralight, save the shipping costs.
2. Full-auto SMT, save the labor costs, reduce the rate of defective products.
3. Over temp protection, IC chips and LEDs are on the same PCB, prolong the LEDs lifespan.
4. Almost without electrolytic capacitor components, more stable, cost reduction.
5. Instant-on, more faster than traditional lights.

Now in LED field, the trend of development is simpler, compact and economic. Under this trend the IC solutions arises at this historic moment, DOB tech market’s growth over 200% every year. Base on continuous improvement of this technology, LONG SUN believe that in the future LED DOB tech light will be keep pace with led light with driver.
