The registration for the "2017 (Eighth) High-Tech LED Golden Globe Awards" is currently in full progress. Many leading LED companies have actively responded and are participating in this prestigious competition. Among them, Shenzhen Shengdie Semiconductor Co., Ltd. (SDS) has officially submitted two award entries: 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 that delivers total harmonic distortion (THD) below 10%, meeting stringent fractional harmonic requirements. It has secured several patents and stands out with its advanced features:
1. Chip-to-chip constant current accuracy deviation of less than ±3%.
2. High power factor with minimal harmonic distortion.
3. Integrated over-temperature, over-voltage, and over-current protection.
4. Line voltage compensation function with adjustable amplitude.
5. PWM interface for smooth, segment, and intelligent dimming.
6. No EMI/EMC issues, simplifying compliance.
7. Simplified circuit design, reducing system cost.
In terms of market competitiveness, the SDS3537BS excels in five key areas:
1. Certified for 3C, Europe, and the U.S. markets.
2. Surge protection level increased by 160%.
3. Reduced surge protection costs by 50%.
4. Increased THD fractional harmonic margin by 40%.
5. Higher single-drive power capacity by 30%.
Compared to traditional LED drivers, the linear IC solution offers fewer components, more stable performance, longer lifespan, and lower production and storage costs. As a result, it has gained widespread adoption among downstream manufacturers, replacing switching power supplies in some applications.
Customers have praised the SDS3537BS for:
1. Excellent surge protection (over 4000V), ideal for high-power systems.
2. Solving THD certification challenges for exports to Europe and the U.S.
3. Reducing component count and saving costs while improving performance.
4. Simple design with intelligent dimming capabilities at an affordable price.
5. High integration, minimizing BOM and simplifying inventory management.
6. Flexible input voltage options.
7. Fewer peripheral components and extended lamp life.
8. No EMI/EMC issues, making certification straightforward.
9. Precise constant current control with line voltage compensation.
10. High power factor and low harmonic distortion.
**Participation 2: SDS3546S**
The SDS3546S is a groundbreaking linear constant current IC that enables RGB gradient dimming and color temperature adjustment. It’s an intelligent dimming solution with memory functionality and is the only product on the market with 1% dimming depth and light cutoff capability.
SDS pioneered this technology with multiple invention patents. The DoB-Driver-on-Board IC is highly integrated, cost-effective, and fully surface-mounted, offering high efficiency, no stroboscopic effect, high PFC, and no EMI/EMC interference. Its simple design makes it easy to certify and highly competitive in the market.
This year, the newly launched SDS3546S breaks through previous limitations with 1% dimming depth and improved shutdown performance, setting a new standard for the industry.
Customers have reported positive experiences with the SDS3546S, highlighting:
1. Solving long-standing dimming and shutdown issues.
2. Achieving 1% dimming depth for superior brightness.
3. Supporting up to 25W per channel, significantly reducing costs.
4. Simple design with intelligent dimming at a cost-effective price.
5. High integration, reducing BOM and streamlining material management.
6. Adjustable line voltage compensation.
7. High constant current accuracy, ensuring stable performance during grid fluctuations.
8. High power factor and low harmonic distortion.
