[Text|High- tech LED reporter Long Zonghui] Recently, Taiwan Accumulation Technology announced that it will launch the 2014 high-tech Golden Globe Award with the original two-stage dimming product MBI6804.
This product is targeted at special occasions and focuses on the use of projectors in the conference room or parking lot market. “Normally, when the projector is used in the conference room, the light is turned off, but our MBI6804 can be used to directly adjust the brightness to the second order. The second-order brightness can be set according to the usage requirements.†He Yi, Director of Accumulation Technology Lighting Products Rui said.
It is understood that there are also three-stage dimming and four-stage dimming on the market. The brightness of the second and third sections of this scheme is fixed, and the accumulation scheme is set by an external resistor, and the range is 20%- Between 50%.
Some luminaire manufacturers use the MBI6804 for parking applications, which is very simple. Especially in the parking lot application, the sensor and the relay are together. When the sensor senses the object, the trigger action can be performed via the power line, and the second-order conversion is performed on the basis of the original dimming. Typical commercially available solutions require additional wiring, while the MBI6804 solution is not required.
"In addition to this, this product also has quasi-resonant function." He Yirui said that there is no quasi-resonant function generally adopts the hard switching method, and the quasi-resonant mode increases the voltage fluctuation on the switch when the output current is cut off. When the voltage is low, the MOS tube switching voltage loss will be relatively small, the efficiency is naturally high, and the EMI performance is also better.
After testing, the MBI6804 with active PFC control, the PF value is easier to maintain at the high water level. The full voltage can easily achieve a PF value of 0.9 or higher. For a specific input voltage, the PF value can be more than 0.99.
“This solution adds dimming function based on the cost of almost the same as non-dimming products. The lamps with dimming function are often expected to sell at a higher price than lamps without dimming, which invisibly improves the manufacture of lamps. The profit of the business.†He Yirui said that customers are welcome to sample and support the MBI6804 of the accumulation technology in the Golden Globe Awards.
At present, the 2014 (5th) High-tech Golden Globe Award - the annual LED good product selection has entered the WeChat voting stage: August 8 - September 30.
