Accumulation Technology provides complete DC and AC dimming solutions

The 19th Guangzhou International Lighting Exhibition was successfully held at the China Import and Export Fair Complex in Guangzhou from June 9th to 12th. Accumulation Technology is also involved in this largest and most influential lighting and LED industry event.

LED driver chip market share ranked second in the world (according to the 2013 IHS report) Accumulation Technology currently has the industry's most complete dimming solution. With the fierce competition in the LED lighting market, lighting products have evolved from specifications and cost competition to impose more stringent requirements on product value. Product reliability, service life, and performance in environmental protection, energy saving, intelligent control, etc. have become the primary consideration for users, especially the need for dimming functions of LED lamps. "Dimming" not only achieves energy-saving purposes by adjusting the brightness of the light source, but also changes the color temperature according to personal preference, creating a different mood environment such as warmth, comfort, and brightness; jumping off the habits of existing lamps, making the light effect configuration more human. Turn.

Compared with traditional light sources, LEDs have the advantages of "controllable and adjustable" in addition to low energy consumption, long life and no pollution. The current common "dimming" requirements can be divided into three categories:

First, functional adjustment light source: such as conference rooms, to help participants concentrate, and to ensure that various briefing media can be clearly played.

Second, enhance the quality of life: through the interaction of light and dark light, cool and warm color temperature, to achieve home lighting and atmosphere.

Third, energy saving and security: adjust the light level of the area in response to public places, such as parking lots, shopping malls, and roads.

Accumulation Technology's dimming solution enhances product differentiation with simple regulation and control, and provides different application scenarios to help customers enhance the value of LED lighting products.

1. Automatic brightness adjustment: The driver chip MBI6911 can increase the intensity of the light source, adjust the amount of light, and reduce energy waste by adding a light sensing resistor in the circuit.

2, temperature automatic balance control: drive chip MBI6911 for high temperature environment and closed luminaire design, add NTC on the drive circuit, can sense whether the temperature of the lamp is too high, progressively reduce the brightness of the lamp, make the temperature drop, help to extend Overall lamp life.

3, manual dimming control: second-order dimming driver chip MBI6804, fourth-order dimming driver chip MBI6904 can be used in the conference room situation, according to different weather conditions and briefing media, manually select the appropriate brightness; in addition, applied to the home situation The light function switches the cool white light to a warm white light source.

4. Mobile sensing: This application has been widely used in parking lots. When the vehicle enters the parking lot, once the sensor is sensed, the original 30% brightness can be changed to the full bright 100% mode. Through the simple power line control (Power Line Control), there is no need to adjust the original wiring, and the construction is convenient.

In this exhibition, Accumulation Technology demonstrated the above dimming solution in the finished product, and also exhibited the driver chip MBI6662 for stage lamps, which features an anode connected to the LED lamp bead to simplify wiring to reduce costs; Decorative lighting driver chip MBI6034: Once the LED is open, shorted, and disconnected during transmission, it is not necessary to send personnel to detect errors through the "human eye". The original data transmission line can be used to obtain error messages, greatly reducing maintenance. People cost.

Accumulation Technology arranged a tea reception during the exhibition. Visitors tasted Taiwan's unique snacks while listening to the product director of the Accumulation Technology Marketing Department to explain the current "lighting", "smart lighting" trends in the LED lighting market and the corresponding solutions for accumulating technology. And research and development technology. During the four-day exhibition, the accumulation technology booth attracted a wave of people to stop and negotiate.
