Mass production of Seoul Semiconductor 100 lm/W AC LED
Seoul Semiconductor's AC LED product Acriche has been mass-produced in Q1 2010 and does not require additional converters.
Diode TVS (Transient Voltage Suppressor), also known as Transient suppression diodes, is widely used a new type of high efficient circuit protection device, it has a fast response time (the nanosecond) and high surge absorbing ability.When it ends of stand moments of high energy shock, TVS can bring the two ends at high rate from high impedance to a low impedance between impedance values, to absorb a large current moment, put it at both ends of the voltage restraint on a predetermined value, thus protecting the back of the circuit components are not affected by the impact of the transient high pressure spikes.

At present, the efficiency of the 100 lm/W Acriche has increased by 25%, reaching the same level as conventional products using AC-DC converters. The company claims that by integrating several 10 small-sized lighting units onto one LED chip, it can be powered by high-voltage alternating current. The LED bulb products made with such chips are 10 times brighter than incandescent lamps.
In addition, the AC-powered Acriche makes it possible to switch on twice in one cycle (1 Hz), and the operating characteristics are as efficient as multiplying the frequency. At 60 Hz AC, its operating frequency is 120 Hz, so the flicker observed at 80 Hz or lower can generally be avoided.
Seoul Semiconductor stated that it will continue to develop more applications that meet customer needs based on Acriche's patented technology.
