Yiguang Technology

Shenzhen Yiguang Technology Co., Ltd. has launched the second-generation 20W, 25W, 30W, 35W, 40W, 50W, 60W high-efficiency and economical LS series LED driver power supply, which is an improved version of the LPS series 0-10V dimming product. It adopts a new hybrid technology and dedicated integrated IC specifically for 0-10V dimming, which is the first in the field of LED driving. The main feature of the second-generation 0-10V dimming product launched is to reduce costs and improve performance, in order to enhance the competitiveness of Yiguang Company's products.

The LS series LED driver adopts QR technology, PSR technology, and reverse down conversion hybrid technology, and improves QR technology to adapt to stable dimming from 0-10V. When the dimming ratio is greater than 80%, the product operates in QR mode to ensure high efficiency and improve EMC; The dimming ratio is less than 80%, and the product operates in DCM mode. As the dimming ratio further decreases, the operating frequency also decreases to ensure dimming stability.

This new hybrid technology reduces the minimum dimming from 10% to 3%, while the actual product specification claims to be 5%. The dimming ratio has been expanded from 10:1 to 20:1, resulting in a significant decrease in dimming depth and a more ideal user experience.

The LS series, due to the use of dedicated integrated ICs and hybrid technology, has reduced the number of product components by more than 30% (compared to the original LPS series), improved product consistency, higher stability, and significantly reduced costs. By adopting this hybrid technology, the efficiency of 0-10V dimming products can reach over 90%, reducing the internal temperature rise of the products and improving their lifespan.

The LS series LED driver, due to the improvement of integration, has a 10% increase in MTBF compared to the LPS series, and the average time between failures of the product is significantly extended.

The LS series LED driver adopts active PFC (Active PFC) power factor correction technology. Under full load conditions, the power factor reaches 99% at 120V input, 97% at 230V input, and 95% at 277V input, with a total harmonic THD distortion of less than 15% @ 277V.

The LS series LED driver adopts the same plastic shell and size as the LPS series, and is encapsulated with thermal conductive silicone. Reduced the internal temperature rise and failure rate of the product.

The LS series LED driver has an ultra wide input voltage range of 90-305V, meeting the application requirements of 277V ± 10% commercial single-phase electricity in North America. The startup time is less than 1 second, the THD is less than 15%, and it meets the DLC standard.

LS series LED driver, with 7 series, namely LS20W LS25W、LS30W、LS35W、LS40W、LS50W、LS60W。 The ability to withstand industrial grade instantaneous lightning surge of 2KV (EN61000-4-5) is suitable for outdoor lighting applications.

The LS series LED driver adopts natural cooling technology and operates in the temperature range of -30 ℃ to 60 ℃. Meet the requirements of indoor and outdoor working environments for users around the world.

The LS series LED driver is equipped with short-circuit protection, overload protection, overvoltage protection, overcurrent protection, and soft start function. Ensure the reliable use of the product.

The LS series LED driver has obtained UL/CUL certification and complies with safety standards such as UL8750, EN61347-1, EN61347-2-13, as well as FCC CLASS B, EN55015, and other standards. This product is applied to LED street lights, LED tunnel lights, LED projection lights, outdoor LED electronic billboards, LED decorative light sources, indoor and outdoor LED lighting, etc. In addition, this product is very suitable for industrial outdoor applications that require dust and high humidity resistance.
