At present, whether it is household electricity, industrial and commercial electricity or public electricity, almost all of them are powered by alternating current. When traditional DC-LEDs are used for lighting, etc., AC-DC converters must be used to convert AC power into DC power. The advantage of this power supply mode is that the DC power is stable and the LED can continuously emit light.
However, in practical applications, the use of AC-DC converters has brought many other problems. The AC-LED uses the principle of a rectifying circuit to enable the LED to operate directly under AC power. However, since the alternating current is periodically changed, the LED may be strobed when it emits light.
The reporter learned that "stroboscopic" is an inherent flaw in AC-LED lighting. At present, the AC-LED scheme using integrated circuit technology makes the illuminating unit and the electronic circuit very small, and is not noticed by the human eye when the alternating current is lower than the forward voltage (VF) value, that is, the LED is not bright. However, this method cannot fundamentally solve the "stroboscopic" phenomenon of the AC LED.
Recently, Sichuan Xinli Light Source Co., Ltd. (hereinafter referred to as Xinli Light Source) has effectively solved the problem of AC-LED by using the newly developed phosphor. When the current period changes, the delay variation of the brightness of the phosphor can be used to effectively compensate for the stroboscopic flash. Technical problems.
“Light engine and intelligent control system are another innovation of Xinli AC-LED lighting products.†Zhao Kun, director of Xinli Light Source R&D Center, revealed that Xinli Light Source integrates LED chip and its driving circuit on the same substrate through system-level packaging technology. In addition, combined with phosphor technology, thermal management design and lighting optical design, etc., made a standard light engine product.
Zhao Kun said that Xinli Light Source has produced a new generation of AC LED lighting products through self-developed AC-LED phosphor technology, which effectively solves the reliability problem caused by the driving power supply and solves the "strobe" of the AC LED. The phenomenon broke through the international patent blockade. At present, Xinli Light Source has applied for 156 LED patents, including 28 domestic invention patents, 5 authorized products, 18 international invention patents and 10 authorized products.
In addition to participating in the 2012 High-tech LED Exhibition, Xinli Light Source will hold a new LED light source LED technology conference on the morning of August 17th at 10:30-11:30 in the D meeting room on the third floor of the Poly World Trade Center in Guangzhou.
