The "2017 (Eighth) High-Tech LED Golden Globe Awards" registration is currently in full progress. Many leading LED companies have already responded positively and are participating in this prestigious event. Among them, Shenzhen Shengdie Semiconductor Co., Ltd. (SDS) has officially submitted two award applications: the "SDS3537BS" Impact Innovation Product Award and the "SDS3546S" Impact Innovation Technology Award.
**Participation 1: SDS3537BS**
The SDS3537BS is a unique linear constant current IC in the market that delivers total harmonic distortion (THD) below 10% and meets all fractional harmonic requirements. It has been granted several patents. The innovation of this product lies in its advanced features:
1. Constant current accuracy deviation between chips is less than ±3%.
2. High power factor with low harmonic distortion.
3. Integrated over-temperature, over-voltage, and over-current protection.
4. Line voltage compensation function with adjustable amplitude.
5. PWM interface for seamless dimming, segment dimming, and intelligent dimming.
6. No EMI/EMC issues in the application system.
7. Simplified wiring and lower power system costs.
In terms of market competitiveness, the SDS3537BS stands out in five key areas:
1. 3C and European/American certifications.
2. Surge level increased by 160%.
3. Surge protection cost reduced by 50%.
4. THD harmonic margin improved by 40%.
5. Single drive power increased by 30%.
Compared to traditional LED drivers, the linear IC solution offers fewer peripheral components, more stable lamp performance, longer lifespan, and lower processing and storage costs. As a result, it's increasingly adopted by LED lighting manufacturers, replacing switching power supplies in certain applications.
Since its launch, the SDS3537BS has gained positive feedback from customers. Some of the testimonials include:
1. Surge protection level exceeding 4000V, ideal for high-power applications.
2. Solves THD certification issues for exports to Europe and the U.S., and also passes domestic 3C certification.
3. Enables high-power products using SMT technology, reducing component count and cost while improving performance.
4. Simple circuit design supports intelligent dimming at a cost-effective price.
5. Highly integrated, reducing BOM materials and simplifying raw material management.
6. One IC input voltage selection option is practical.
7. Fewer peripheral components lead to longer lamp life.
8. No EMI/EMC issues, making certification easier.
9. Line voltage compensation with adjustable amplitude ensures high constant current accuracy. Even with grid fluctuations, power variation is minimal (1% per 10V).
10. High power factor and low harmonic distortion.
**Participation 2: SDS3546S**
The SDS3546S is a linear constant current IC designed for RGB gradient dimming and color temperature control. It’s an RGB linear constant current driver IC that provides an intelligent dimming solution with memory functionality. It is the only linear constant current IC on the market with a light cutoff and a dimming depth of 1%.
SDS was the first to develop and patent this invention. The linear constant current digital driver IC is a DoB-Driver-on-Board solution. It features a simple structure, low cost, and full SMT production, ensuring high efficiency and intelligent dimming without stroboscopic effects, high PFC, and no EMI/EMC interference.
This IC is easy to certify and is highly competitive in the market due to its cost-effectiveness. This year, SDS launched the SDS3546S, which breaks through the limitations of dimming shutdown and achieves a dimming depth of 1%, once again leading the linear constant current driver IC industry.
In the LED industry, driver ICs may not be the most visible component, but they play a critical role in achieving intelligent lighting. The technical content is high, and the driver IC sector is more semiconductor-focused. Since its release, the SDS3546S has received strong recognition from customers. Feedback includes:
1. Solving long-standing issues with dimming and shutdown.
2. Achieving a dimming depth of 1%, providing excellent brightness.
3. A single chip can support up to 25W, significantly reducing costs.
4. Simple wiring allows for intelligent dimming at a low cost.
5. Highly integrated design reduces BOM materials and improves raw material management.
6. Line voltage compensation with adjustable amplitude.
7. High constant current accuracy, with minimal power fluctuation during grid instability.
8. High power factor and low harmonic distortion.
