The "2017 (eighth) high-tech LED Golden Globe Awards" registration work is in full swing. At present, many LED companies have responded positively and participated in the selection of the high-tech LED Golden Globe Award. Among them, Shenzhen Shengdie Semiconductor Co., Ltd. (hereinafter referred to as “SDSâ€) has officially registered two awards: “SDS3537BS†Impact Innovation Product Award and “SDS3546S†Impact Innovation Technology Award.
Participation 1: SDS3537BS
SDS3537BS is the only linear constant current IC in the market with a total harmonic less than 10% and meeting the requirements of each fractional harmonic. It has obtained relevant patents. The innovation and advancement of this product are mainly reflected in the following aspects:
1. The constant current accuracy deviation between chips is <+/-3%;
2. High power factor and low harmonic distortion;
3. With over temperature, over voltage, over current protection;
4. With line voltage compensation function, the compensation amplitude can be set;
5. With PWM interface, it can realize stepless dimming, segment dimming, and intelligent dimming function;
6. The application system has no EMI/EMC problems;
7. The line is simple and the power system cost is low;
In addition, SDS3537BS is highly competitive in the market, mainly in the following five aspects:
1, 3C / European and American certification;
2. The surge level is doubled (+160%);
3. The surge protection cost is greatly reduced (-50%);
4. THD fractional harmonic margin increases (+40%);
5. Single drive power is increased (+30%).
Compared with the traditional LED driver power supply, the linear IC solution has the advantages of less peripheral components, more stable lamp performance, long service life, and lower cost of processing and storage.
Based on the above advantages, the linear IC solution has gradually been adopted by the majority of LED lighting downstream application manufacturers, replacing the switching power supply in some product solutions. SDS3537BS products from SDS (SDS) have been introduced to the market for less than one year, and have been well received by customers. The following are some customer reviews:
1. Surge protection level over 4000V, it is advantageous to do high power;
2. Solved the problem of THD certification for export to Europe and the United States, and domestic 3C certification can also be passed;
3. Do high-power products, patch technology, save a lot of components, save a lot of cost and improve performance;
4. The whole line is simple, and it can realize intelligent dimming, which is cost-effective;
5. Highly integrated, less BOM raw materials, convenient storage and management of raw materials;
6. One IC input voltage selection, practical;
7. There are few peripheral components and the whole lamp has a long service life;
8. No EMI/EMC problems, certification is easy and simple;
9. With line voltage compensation function, the compensation amplitude can be set and the constant current precision is high. When the power grid fluctuates, the power fluctuation is small (1% fluctuation per 10V power);
10. High power factor and low harmonic distortion;
Participation 2: SDS3546S
SDS3546S is a linear constant current IC that realizes RGB gradient dimming color temperature. It is an RGB linear constant current driving IC technology. It is an intelligent dimming solution with memory function. It is also the only one on the market. Linear constant current IC technology with light cutoff and dimming depth of 1%.
It is understood that SDS is the first to develop and award a number of invention patents. The linear constant current digital drive IC is a DoB-Driver on Board. Its components are simple, low cost and full patch. Production and processing, high efficiency, and can also achieve intelligent dimming, no stroboscopic, high PFC, no EMI / EMC interference.
The linear constant current digital driver IC can be easily and easily certified, and is a competitive and cost-effective product on the market. This year, SDS's newly launched SDS3546S breaks the dimming shutdown and dimming depth of 1%. It will once again lead the linear constant current drive IC industry.
In the LED industry, the share of driver ICs is not large, and attention is not too much, and the technical content is not low. Strictly speaking, the driver IC is more biased towards semiconductors, and it is also one of the most critical aspects of achieving intelligent lighting. The SDS3546S technology has been highly recognized by customers since its launch. The following are some of the customer's evaluations:
1. Solve the dimming and shutting down problem that has been plagued all the time;
2, the dimming depth reaches 1%, it is very bright;
3, a single can achieve 25W, saving a lot of costs;
3, the whole line is simple, can also achieve intelligent dimming, cost-effective;
4, highly integrated, less BOM raw materials, convenient storage and management of raw materials;
5, with line voltage compensation function, the compensation amplitude can be set;
6. Constant current accuracy is high. When the power grid fluctuates, the power fluctuation is small;
7, high power factor and low harmonic distortion.
