Yiguang Technology

After one year of hard work by technical personnel from Shenzhen Yiguang Technology Co., Ltd., we have developed a new generation of high-power, high-density, high-efficiency, and long-life LY series LED driver power supplies for 50W, 60W, 75W, 90W, 100W, 120W, 150W, and 200W. This is a new series of low-cost products launched after the LD series and LG series UL certified products, completing Yiguang's low-cost LED power supply series in the high-power range. To meet the low-cost demand for high-power LED street lighting.

The LY series LED power supply adopts QR technology and LLC technology, and integrates LLC technology with the sixth generation COOLMOS new devices and modules, resulting in an energy conversion efficiency of up to 95%, significantly reducing the internal temperature rise of the product and improving its lifespan.

The LY series LED power supply adopts ultra-high frequency 330KHZ resonance and full wave rectification design technology, achieving the level of no output electrolytic capacitor design, making the lifespan of this series of products more than 1.5 times that of similar LED products.

The LY series LED power supply has a volume of only 350cm3 and a power density of 0.62W/cm3, which is twice that of similar products. Significantly reduced the cost of the product's casing, glue filling, and other major components.

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

The LY series LED power supply adopts a metal aluminum shell and is sealed with thermal conductive black glue. Reduced the internal temperature rise and failure rate of the product.

The LY series LED power supply is designed with uniform temperature, ensuring a lifespan of over 100000 hours for the products.

The LY series LED power supply adopts a two-stage surge absorption circuit and a first stage lightning arrester, which enables the product to withstand industrial grade instantaneous lightning surge of 4KV (EN61000-4-5), suitable for the needs of outdoor lighting applications.

The LY series LED power supply 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 LY series LED power supply has three series, namely LY50W LY60W、LY75W、LY90W、LY100W、LY120W、LY150W、LY200W。 Allowing a wide range of output voltages, with a maximum output voltage of 445V.

The LY series LED power supply has five types, namely: fixed constant current type, fixed constant voltage type, 0-10VDC dimming type, PWM dimming type, and RD potentiometer dimming type. Dimming products, add - DD- PD、-RD。 Dimming products will add two control lines.

The LY series LED power supply uses natural cooling technology to operate within a temperature range of -40 ℃ to 60 ℃. Meet the requirements of indoor and outdoor working environments for users around the world.

The LY series LED power supply is equipped with short-circuit protection, overload protection, overvoltage protection, and overcurrent protection. The LY series LED power supply has applied for UL/CHUL/CQC/CE certification and adopts safety standards such as UL8750, EN61347-1, EN61347-2-13, as well as EMC CLASS B. 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.

The external dimensions of LY series products are: 126mm (length) x 59mm (width) x 36mm (height) (50W-75W)

The external dimensions of LY series products are: 150mm (length) x 59mm (width) x 36mm (height) (90W-100W)

The external dimensions of LY series products are 170mm (length) × 59mm (width) × 36mm (height) (120W-200W)
