Throughout the years, "de-powering" has been a widely debated topic. In reality, the current market suggests that "de-powering" is not actually about removing power. Rather, it should be understood as a technical term known as "DOB," which is neither unfamiliar nor fully matured yet.
Currently, DOB technology is gradually gaining acceptance in the market, with performance indicators becoming increasingly refined. More and more LED manufacturers are starting to offer DOB-based products. The market size of DOB is already estimated to make up at least 30% of the total LED lighting market.
But what exactly is DOB? In essence, it's a type of carrier-based LED that integrates both the light source and the power supply solution onto a single carrier. This design creates a unified LED module tailored for specific lighting applications.
Xingguangbao has made significant strides in researching and developing DOB light engine technology, offering a range of DOB light engine series products to meet market demands. To date, they have launched several product lines, including the circular light-emitting surface (golden bowl) light engine, the integrated certified high-end light engine, and the 5054 super-large luminous surface light engine.
In the “2017 (8th) High-tech LED Golden Globe Awards,†Xingguangbao submitted its “DOB-Light Engine†product for the Innovation Product Award.
This product is a high-power (200W) large-luminous-surface flip-chip DOB light engine, developed to address common issues in the market such as unstable power supply schemes, limited voltage ranges, and poor lightning surge resistance.
The product features a flip-chip design along with a mature power and IC solution. Key features include:
- Large luminous surface
- Up to 200W per unit
- Wide voltage range: AC 180-300V
- Constant current accuracy: less than 2%
- Lightning surge resistance: up to 4000V
This innovative product effectively solves the instability issues of existing DOB power supply solutions. Its wide voltage compatibility allows it to meet diverse market requirements. With high current precision and strong lightning resistance, it's often referred to as the "never-extinguishing light source." Since its launch, the product has received positive market feedback, with zero customer complaints reported so far.
In addition to the DOB light engine, Xingguangbao also entered its innovative product, the "Built-in IC 5050RGB" light source, into the annual innovation product award competition for the Golden Globe Awards.
Most RGB products on the market use external ICs, where one IC controls multiple LED lamp beads. This setup can lead to stability issues—if one IC fails, all connected LEDs may stop working.
To address this problem, Xingguangbao developed the built-in IC 5050RGB lamp bead, which integrates the IC directly within the lamp bead during the packaging process. Each IC controls only one lamp bead, ensuring that if one fails, it only affects a single LED, leaving others unaffected.
A company representative explained that the built-in IC 5050RGB was launched in September of this year and has shown excellent stability, significantly reducing the risk of product defects and improving overall quality.
