Compared with traditional lightings, such as HID,Metal halide, HPS lamps, LED Lighting’s most advantage is energy saving. It needs only 30%-50% power to produce the same or better lighting effect. What is worth mentioning is that we can also use dimming sensor(microwave sensor) to save more energy.

Fireflier lighting have perfect solution of dimming sensor for most of our led high bays.

How do dimming sensor of led high bay works?

The MC601V innovative and active motion detectors with HF system 5.8GHz. Motion can be detected through plastic, glass and thin non-metal materials. The sensors allow energy saving without compromising comfort. When used in combination with 1-10V dimmable LED drivers or ballasts, they can achieve 3-step dimming function, which is perfect for use in some areas that requires a light change notice before totally switch off. Also, the 1-10V interface in the sensors can match up with Merrytek stand-alone daylight sensor MS01, and implement daylight harvesting, means the lighting system has automated controls that either turn off or dim artificial light in response to the available daylight in the space. As it uses the third generation Merrytek technology, normal 5.8GHz microwave module can easily reach high mounting high up to 15m and long detection area 10m in radius.

3-step dimming function

Lamps in corridor are controlled by several sensors. Once any motion is detected by one of sensors, the motion signal will be transmitted to other sensors connected together. Then, all lamps switch on at the same time, instead of switching on the lamps in the area where motion is detected.

ON -OFF Function

Motion sensor MC601V + LED driver or ballast (Any brand)

MC601V is an innovative motion sensor, switch on the light on detection of movement, and switch off after a hold time when there is no motion detected. As built-in daylight sensor can read brightness value, the sensor does not switch on the light if with sufficient natural light.

Daylight Harvesting

When used in combination with Merrytek daylight sensor MS01, the system has automated controls that either turn off or dim artificial light in response to the available daylight in the space.
