LED power supply is a kind of supporting equipment of LED lamps. LED ultra-thin waterproof power supply, as the name suggests, ultra-thin, thin thickness, can adapt to a smaller installation space; Waterproof, the better quality power supply on the market generally uses IP67 waterproof grade, used for outdoor rain weather is enough to demand. LED ultra-thin waterproof power supply is mostly used in outdoor places, of course, indoor can also be installed and used, can be very good insect and dustproof.
LED power supply is the power supply into a specific voltage to drive the LED light voltage converter, LED power supply has a constant voltage source and a constant current source, today here about the constant voltage source, usually: LED power supply input high voltage power frequency AC (that is, mains), through the LED power supply conversion output specific voltage value.
Next, I will introduce the matters needing attention when purchasing LED ultra-thin waterproof power supply. A good driving power supply should meet these requirements:
1. High reliability is especially like the driving power supply of LED street lamps. It is installed at high altitude, so it is inconvenient to maintain and the maintenance cost is high.
2. High efficiency LED is an energy-saving product, and the efficiency of the driving power supply is high. For the structure of the power supply installed in the lamp, it is particularly important. Because the luminous efficiency of LED decreases with the increase of LED temperature, the heat dissipation of LED is very important. The efficiency of the power supply is high, its loss of power is small, and the heat is small in the lamp, which reduces the temperature rise of the lamp. It is beneficial to delay the light decay of LED.
3. High power factor: power factor is the load requirement of the power grid. General 70 watts below the use of electrical appliances, without mandatory indicators. Although the power factor of a single electrical appliance with small power is a little low, the influence on the power grid is not big, but at night when people light the lights, the same kind of load is too concentrated, will produce more serious pollution to the power grid.
4. Surge protection: the ability of LED to resist surges is relatively poor, especially the ability to resist reverse voltage. It is also important to strengthen protection in this area. Some LED lights are installed outdoors, such as LED street lamps. Due to the power grid load and the induction of lightning strikes, various surges will be invaded from the power grid system, and some surges will cause the damage of LED. Therefore, the LED driving power supply should have the ability to inhibit the invasion of the surge and protect the LED from being damaged.
6. Protection function: the general quality of the middle to high-end LED ultra-thin waterproof power supply has protection function, such as the D series ultra-thin waterproof power supply of Yashoda Technology has built-in over-voltage protection, overload protection, short-circuit protection and over-temperature protection function.
7. The life of the LED power supply should be matched with the life of the LED. The life of the general LED lamps is longer, but this is not the actual service life. Good quality LED power supply, especially with anti-surge ability of the LED power supply can effectively extend the actual service life of LED lamps.
8. Comply with safety regulations and electromagnetic compatibility requirements.
So LED ultra-thin waterproof power supply, high reliability is the key.
