Yiguang Technology

After one year of hard work by technical personnel from Shenzhen Yiguang Technology Co., Ltd., we have developed the second-generation LP series LED driver power supplies with small size, high efficiency, and economy, including 12W, 20W, 25W, 35W, 40W, 50W, 75W, and 96W. This is the second generation of low-cost products with constant current and constant voltage, following the LPS series, LAG series, and LY series UL certified products, which enhances the competitiveness of Yiguang's products. To meet the low-cost requirements of LED constant current driving power supply.

The LP series LED power supply adopts QR technology and PSR technology, achieving an energy conversion efficiency of up to 91% for power products in the 12W-50W power range, significantly reducing size, lowering costs, reducing internal temperature rise, and improving product lifespan.

The high efficiency and low temperature rise of LP series LED power supply make the lifespan of this series of products more than 1.5 times that of similar LED products.

The power density of the LP series LED power supply reaches 0.35W/cm3, which is twice that of the first generation products of the same power level. Significantly reduced the cost of the product's casing, glue filling, and other major components.

The LP 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 LP series LED power supply adopts a plastic shell and is sealed with thermal conductive silicone. Reduced the internal temperature rise and failure rate of the product.

The LP series LED power supply is designed with uniform temperature, ensuring a lifespan of over 100000 hours and a maximum lifespan of 175000 hours.

The LP 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 startup time is less than 1 second, the THD is less than 15%, and it meets the DLC standard.

The LP series LED power supply has 8 series, namely LP12W LP20W、LP25W、LP35W、LP40W、LP50W、LP75W、LP96W。 Among them, LP75W and LP96W are three wire inputs with a fixed grounding wire. The ability to withstand industrial grade instantaneous lightning surge of 6KV (EN61000-4-5) is suitable for outdoor lighting applications.

LP series LED power supply, maximum output current 8.33A, maximum output voltage: 285V. There are constant current and constant pressure types.

The LP series LED power supply uses natural cooling technology to operate in the temperature range of -30 ℃ to 60 ℃. Meet the requirements of indoor and outdoor working environments for users around the world.

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

The LP series LED power supply has obtained UL/CUL certification and complies with 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.
