Light up outdoor power supply protection

Are hue outdoor lights waterproof?

CONNECT YOUR OUTDOOR LIGHTS - Connect multiple Hue low-voltage outdoor lights up to a total of 100W. WEATHERPROOF - These fixtures are specially designed for use in outdoor environments and have undergone rigorous tests to ensure performance. They are IP44 rated which means they're protected against water splashed from any direction.

Can SMPS be used in outdoor LED lighting?

SMPSs are not typically used in outdoor settings, so there are a number of special considerations for their use in outdoor LED lighting applications. One particular area of concern is the SMPS front end. Here, the most immediate threat is overvoltage failures.

Do LED lights need circuit protection?

In any LED lighting application, there are several areas where effective circuit protection will increase reliability. Those areas include the AC portion of the circuit prior to DC rectification, a DC section, and protection for the LEDs themselves. The first line of defense is the AC line fuse in the SMPS front-end.

What is a typical protection device for overvoltage?

The typical protection devices for overvoltages include MOVs (metal oxide varistors) or solid-state devices. With energy ratings from 0.1 to 10,000 joules and typical peak current ratings from 40A to 70kA (based on standard 8x20 test waveforms), MOVs divert transient currents to ground and away from sensitive circuits.

What is open led protection?

With wide operating temperature ranges, from -40 to +150C, open LED protection can be used in extreme environments often with minimal derating. Recall that one of the biggest concerns in LED operation are thermal conditions. Open LED protection devices usually have low on-state voltage, typically 1.5V, and a low off-state current.

How do I select an open led protector?

Properly selecting an open LED protector requires that the compliance voltage is known. This is the open-circuit voltage of the constant current source. When an LED fails, the compliance voltage will appear as a voltage drop across the failed LED.
