One of the factors affecting the life of LED products-LED driver

September 14, 2022

Several key factors affecting Led Lighting products are heat dissipation, driver, and light source. At the same time, heat dissipation is particularly important. The heat dissipation effect directly affects the life quality of lighting products, as well as the life of the driver itself. The stability of the output current and voltage also has a great impact on the overall life quality of the product. The light source is the core part of the whole product. Today, I will introduce the driver to you.
1. What is an LED driver power supply?
The LED driver converts the power into a specific voltage and current to drive the LED lighting voltage converter. Usually, the input of LED driver includes high-voltage power frequency AC (ie, mains electricity), low-voltage DC, high-voltage DC, and low-voltage high-frequency. Alternating current (such as the output of an electronic transformer). The output of the LED driver is mostly a constant current source, which changes the voltage with the change of the forward voltage drop of the LED, such as LED Linear Light, Light Trunking System and so on. And our customized Led Grow Light Kit for customers uses a constant voltage drive. Because the four light bars need to be switched separately. This is a custom-made product.
2, LED drive power features
(1) High reliability
It is especially like the driving power of LED street lights. It is installed at high altitude, it is inconvenient to maintain, and the maintenance cost is also large.
(2) High efficiency
LEDs are energy-saving products, and the efficiency of driving power supplies is high. It is very important to dissipate heat from the power supply installed in the fixture. The power supply has high efficiency, its power consumption is small, and the heat generated in the lamp is small, which reduces the temperature rise of the lamp. It is beneficial to delay the light decay of LEDs.
(3) High power factor
The power factor is the grid's load requirements. Generally, there are no mandatory indicators for electrical appliances below 70 watts. Although the power factor of a single power consumer with low power has little effect on the power grid, the amount of lighting used at night is large, and the similar load is too concentrated, which will cause serious pollution to the power grid. For 30 watts to 40 watts of LED driver power, it is said that in the near future, there may be certain indicators for power factors.
(4) Surge protection
The ability of LEDs to withstand surges is relatively poor, especially against reverse voltage capability. It is also important to strengthen protection in this area. Some LED lights are installed outdoors, such as LED street lights. Due to the start of the grid load and the induction of lightning strikes, various surges will be invaded from the grid system, and some surges will cause LED damage. Therefore, the drive power supply should have a certain lack of surge protection, and as the power supply and lamps are frequently replaced, the LED drive power supply must have the ability to suppress the intrusion of surges and protect the LED from damage.
(5) Protection function
In addition to the conventional protection function, the power supply preferably increases the LED temperature negative feedback in the constant current output to prevent the LED temperature from being too high; it must meet the requirements of safety regulations and electromagnetic compatibility.

LiteHome LED lighting adopts the power supply of international big brands. Such as OSRAM, BOKE, Philips and other certified drivers. So the quality of our Modern Linear Light Fixture is very guaranteed.
