When a conventional DC-LED is used for illumination or the like, an AC-DC converter must be used to convert AC power into DC power. However, in practical applications, the use of AC-DC converters has brought problems such as efficiency, cost, volume and electromagnetic compatibility. As a result, people turned to R&D LEDs (AC-LEDs) that are more compatible with traditional power supplies. AC-LED uses the principle of rectification circuit, although LED can work directly under AC power, but due to the periodic variation of AC power, LED will produce severe stroboscopic phenomenon when it emits light.
Xinli Light Source is based on the rare earth luminescent material with controllable afterglow time, and proposes a new generation of AC LED technology to creatively solve the stroboscopic problem that is common to AC LEDs. The AC LED bulb developed has a fluctuation depth of less than 40% under the condition of a power factor greater than 0.8, which makes LED lighting products more efficient, more reliable, safer, longer lasting, more cost-effective, and better for better propulsion. Industrial upgrading of the industry.
