Advantages of Waterproof LED Power Supplies
1. Moisture and Water Resistance: Designed to withstand water, moisture, and humidity, making them
suitable for outdoor environments, damp areas (like bathrooms,
kitchens), or locations prone to splashes.
2. Durability in Harsh Conditions: Resistant to dust, dirt, and corrosion, ensuring stable
performance even in challenging weather (rain, snow, high humidity)
or industrial settings.
3. Enhanced Safety: Reduce the risk of short circuits, electric shocks, or equipment
damage caused by water exposure, providing reliable protection for
both the power supply and connected LED systems.
4. Extended Lifespan: Protected from water and environmental contaminants, they maintain
consistent operation over a longer period compared to
non-waterproof alternatives, minimizing replacement needs.
5. Versatile Applications: Compatible with outdoor LED lighting (streetlights, landscape
lights, signage), marine lighting, and indoor damp-area lighting,
offering flexibility in installation scenarios.
6. Stable Performance: Maintain stable voltage and current output even in wet conditions,
ensuring the connected LED modules or fixtures work efficiently
without flickering or failure.
7. Weatherproof Ratings: Typically come with IP (Ingress Protection) ratings (e.g., IP67,
IP68) that clearly indicate their level of water and dust
resistance, helping users choose the right product for specific
environments.
Characteristics of LED Power supplies
- 1.High Reliability: Especially for the driving power supplies of LED street lights,
which are installed at high altitudes. This makes maintenance
inconvenient and relatively more costly.
- 2.High Efficiency: LEDs are energy-saving products, so the driving power supply
needs to be highly efficient. In this case, the structure of the
power supply installed inside the LED luminaire is particularly
important.
- 3.High Power Factor: Power factor is a requirement imposed by the power grid on loads.
Generally, there are no mandatory standards for electrical
appliances with a power rating below 70 watts.
- 4.Surge Protection Function: LEDs have poor resistance to surges, especially reverse voltage.
Therefore, it is necessary to enhance protection in this aspect.
- 5.Protection Functions: In addition to conventional protection functions, it is advisable
to add LED temperature negative feedback to the constant current
output to prevent LEDs from overheating.
