Seoul Semiconductor held a press conference in Korea, the US and China yesterday (August 26th) to introduce its Acriche A4, a new LED product with luminous efficiency up to 75lm/W.
According to Seoul Semiconductor, the new Acriche A4 product is capable to satisfy both CRI and brightness. The past requirement of lowering luminous efficiency by several tens of percent is overcome by the A4. The A4 devices have a color temperature of 3000K and include multiple new technologies provide excellent efficiency of 75 lumens per watt (lm/W) with a High CRI of 85.
Alternating Current (AC) LED’s with better luminous efficiency than LED’s with Direct Current (DC) for the first time is very significant, according to company.
Significant advantages of the Acriche A4 series include:
▲It is possible to use Acriche products on AC power freely between 100V and 230V without additional conversion. Only a simple, inexpensive diode bridge is required.
▲Different than other Acriche products (such as the popular A2 and A3 series), the A4 uses 50Vrms per package and 110V-220V can be achieved by connecting multiple devices in whatever manner is needed.
▲Whether used in light bulbs or light structures with arrays of LED’s, the best suitable design is guaranteed due to the degree of freedom of placement and configuration of the A4.
