取扱説明書

The NLH series have brightness equivalent to that of mercury lamps ranged between 250 W and 400 W. Combined use of aluminum body with heat radiation fins and plastic material realizes high heat dissipation, high rigidity and light weight. It achieved both energy saving and safety. The power supply and the LED light are separated for the purpose of thermal dispersion, and because of its waterproof performance (IP 67) it is active in various environments. In addition, the NLH series lights turn on more quickly than mercury lamps.

<Applications> Factory, refrigerated warehouse, road, gymnasium, indoor parking lot, etc.
* Please install the included falling prevention wire when installing.

Three Times or Greater International Standard

high lightning surge.

This product has surge protection devices(SPDs) inside, which quickly bypasses the induced lightning surge. International Standard (IEC61000-4-5) requires 2kV for differential mode and 4kV for common mode, respectively. This product withstands 15kV of high lightning surge.

Measures against flicker

Why constant current power supply required?
The cause of flicker is ripple

To ensure reliability by operating the LED within the maximum rated current. In the absence of a constant current power supply, the LED is driven by a current circuit using a resistor,
If the voltage fluctuates, the current flowing inside LED fluctuate, continued use exceeding the rated current will degrade the LED and reduce the illuminance.
In addition, even if the surge enters the power supply, the surge protection devices inside the power supply prevents from the LED broken.

The power supply input which mainly uses AC passes through the rectifiering and the smoothing circuits, but the AC component remains.

This is called ripple and causes flickering of LED, which induces fatigue and stress, so the power supply with less ripple is desired.
