Patio light NLH200U series
Patio lights specially designed for use in low temperature environments. -30℃ working environment is very suitable for refrigerated warehouse lighting.
It has the same brightness as 800W mercury lamp.
The lamp body is composed of large-area aluminum alloy fins and resin material to achieve high heat dissipation, high sturdiness and lightweight, making it both energy-saving and safe.
The power supply is separated for heat dissipation and has an IP65 waterproof protection level, making it adaptable to a variety of environments.
In addition, compared with mercury lamps, it can meet the demand for instant lighting.
Applicable
Factories, refrigerated warehouses, stadiums, parking lots, etc.
※Be sure to install anti-falling steel cables during installation.

Lightning strike protection ability
Use lightning protection design to prevent lightning surges, thereby protecting the lamps from damage caused by lightning. (The burst waveform may cause a discharge of 10KA within 8/20μs)
If a direct lightning strike or induced lightning strike occurs, surge waves may be conducted by wires, causing damage to electronic machinery. This lighting product contains a lightning surge protection circuit.
The line withstand is ±6kV
3 times
the international standard
Withstand ±15kV to ground
3.75
times the international standard
SPD (lightning arrester)
Protect LED floodlights by limiting the instantaneous fluctuation current (surge) generated by lightning.
A general lightning strike will cause an electric shock of tens of kV or more, but this LED lamp has an SPD between the power supply and the ground, so when an electric shock occurs, the surge will pass through the SPD and the ground, and discharge current back to the ground.
※When using this lamp, be sure to connect it to ground.
Flicker Countermeasures
Reasons why "constant current" is needed
The cause of the flickering is "ripples"
Constant current can prevent excessive current and maintain illumination stability. In the case of a constant current, once the voltage increases, the current flowing through the LED will also increase, and the illumination will become brighter. However, excessive current will cause the LED to deteriorate, resulting in reduced brightness and poor quality.
Furthermore, when the current value changes, the luminous brightness will also change accordingly. To maintain the lighting quality, a constant current drive is required.
In addition, the constant current power supply is designed with an electric shock protection circuit, and the LED will not be damaged even if an electric shock enters the power supply.
In addition, the input voltage of the constant current power supply is alternating current. Therefore, after passing through the rectifier circuit, it will also pass through the smoothing circuit, leaving only a very small amount of AC voltage change.
We call these AC voltage components stroboscopic. Flicker can causeLED flashing, thus causing fatigue and stress, so our products use very little power flickering.
