Dimmable LED Driver with Sound Sensor

Imagine you are driving your car down the entrance ramp to the underground parking garage. All you see is pitch darkness down there. So you need to get off the car, fumbling for the light switch on the garage wall. What a daunting task it would be to just park your car.

It is time for the parking garage to have a sound sensor that detects sound when the car is approaching. To save electricity, you might also consider buying LED lights which means the LED driver is a must as well.

In that case, our dimmable LED driver with sound sensor would be an ideal fit for the occasion. It uses the sound sensor to control the output DC current supplied to LED light. When cars or people make sounds higher than 50dB, the dimmable driver will allow maximum output current to flow to the LED light.

The light would keep on lighting at its maximum capacity for one minute. After the surroundings quiet down, the dimmable LED driver would automatically return to the state of low current output.

This LED power source eliminates the need for manual handling task by using the sound sensor. It also helps save a large amount of energy.

Beyond the parking lot, our dimmable LED power supply also can be installed in the passageway, passenger conveyor, toilet, and other public places.

Specifications of the Dimmable LED Driver
1. Built in active PFC, PF≥0.95
2. Efficiency >87%
3. Terminal Block Connection System
4. Power: 12W
5. Output DC voltage:50-80V, customizable
6. Output DC current: 150mA (when the sound level exceeds 50dB), 20mA (when the sound level is below 50dB). Upon your request, we can custom design the LED driver to have a maximum output current of 500mA.
7. Size: 110×25×18mm (L×W×H)

Advantages
1. This dimmable LED driver uses 2w of electrical power when operating at the current of 20mA. It would consume 12W for 60 seconds if operating at full load.
2. Jumper is used for current control.
3. Sound sensitivity can be changed via the potentiometer.
4. High-quality components are used to ensure minimal heat build-up, small temperature increase, and constant current output.
5. The capacitors can last for more than 6000hours at a high operating temperature of 105℃.
6. Our LED driver can be customized according to your detailed requirements.
