LED driver the key components in the LED lighting produts. LED driver fail, the Whole LED light fixture will fail. It is like the heart of a person. So choose the right and the reliable LED driver is the most important for a LED lighting products. This blog will bring you know more about the LED driver knowledge.

Features of LED power driver supply
- high reliability
Especially the driving power of the LED street lamp is installed at a high altitude, so the maintenance is not convenient, and the cost of maintenance is also large.
- high efficiency
LED is an energy-saving product, and the efficiency of driving power is high. It is very important for the power to be installed in the luminaire. The power supply’s efficiency is high, but the power consumption is small, and the heat in the luminaire is small, so the temperature rise of the lamp is also reduced. As a result, delaying LED attenuation is advantageous.
- high power factors
The power factor is the power grid’s demand for the load. In general, there are no mandatory indicators for electrical appliances with a power rating of fewer than 70 watts. Although the power factor of a single electric appliance is low, it has little influence on the power grid; however, in the evening, the power grid will be seriously polluted by a large amount of lighting and the concentration of the same kind of load. There may be some index requirements for power factors for the 30 watts-40 watts LED driver in the near future.
- driving mode
Now there are two kinds of traffic: one is a constant voltage source for multiple constant current sources, and each constant current source is supplied to each LED individually. In this way, the combination is flexible, and all the LED failures do not affect the work of other LEDs, but the cost will be slightly higher. The other is the direct constant current power supply, that is, the drive mode of “Keke Hui Bao”, which is driven by LED in series or parallel operation. It has the advantage of low cost but poor flexibility, and it also does not affect other LED operation problems when solving an LED failure. The two forms coexist in a period of time. The way of multi-way constant current output power will be better in terms of cost and performance. Maybe it’s the main direction in the future.
- surge protection
The ability of LED to resist surge is relatively poor, especially the ability to resist reverse voltage. It is also important to strengthen the protection in this area. Some LED lights are outdoors, such as LED street lights. Because of the load shedding and lightning induction, all kinds of surges will be invaded from the power grid, and some surges will cause LED damage. Therefore, the analysis of the driving power of “Zhongke Hui Bao” should be deficient in surge protection. As for the frequent replacement of power and lamps, the LED driver should have the ability to suppress the surge and protect the LED from being damaged.
- protection function
To meet the requirements of safety and electromagnetic compatibility, it is best to increase the LED temperature negative feedback in the constant current output, in addition to the conventional protection.
What is an LED driver
LED driver is a component that used to controls the power of an LED or multiple-layer LED PCBs. In short, it’s a vital part of an LED circuit. Thus, operating without an LED driver means doom for an LED system.
LED driver types
LED driver is a component that used to controls the power of an LED or multiple-layer LED PCBs. In short, it’s a vital part of an LED circuit. Thus, operating without an LED driver means doom for an LED system. But LED drivers could be a tricky technology because there are various types. And it’s a bit overwhelming most times. Many people know a little about LED driver but not full. This blog will be helpful for you to understand about it.
2.1 AC LED driver
AC LED driver is also called high voltage LED driver or Off-Line LED driver which takes line voltage, either low line (100-120VAC) or high line (200-240VAC). Using off-line drivers cuts out the need for a switching power supply like you would need when using low voltage (DC input) LED drivers. AC LED drivers take power from your line source and output a DC voltage range while keeping your LEDs at a constant drive current. The widely ued AC LED driver includes 100W LED driver, 30W LED DRIVER, 50 watt led driver. It ranges from 10W to 500W.
2.2 DC LED driver
DC LED driver is a low voltage LED driver. DC Input or Low Voltage LED drivers take DC voltage from a battery or switching power supply and output a constant current so as to keep the LED safe. This way, when the LED’s electrical characteristics change due to heat, the LED will stay at a safe driving current, while the voltage can vary depending on the LEDs needs.
12V LED DRIVER: 12V LED driver power supply or 12V DC Power supply is one of the most commonly used power supplies currently in use. It means the power supply transfer from 120V or 240V high input voltage to low DC 12 Voltage.
24V LED DRIVER: 12V LED driver power supply or 24V DC Power supply is one of the most commonly used power supplies currently in use. It means the power supply transfer from 120V or 240V high input voltage to low DC 24 Voltage.
2.3 Constant Current LED driver
According to the driving mode, the common market-led lamp driver is divided into two kinds. One is constant current drive. The characteristic of a constant current drive is that the output current is constant. The output voltage is changed in one range. So we often see that the driving shell is marked out (output: DC**V – **V * * * mA+-5%) in the market. This means that the output voltage is in one of the output voltages. The range, the current is how many ma.
2.4 Constant Voltage LED driver
And the other is the constant voltage drive. The constant voltage driving characteristic is that the output voltage is fixed, and the current is limited to the maximum value with the change of the lamps and lanterns. In this case, the shell usually indicates (output: DC**V **A) the voltage of the output fixed volt, and how many maximum output currents are available. The most common output voltages in the led market are 5V, 12V, 24V, and so on.
2.5 Dimmable LED driver.
A dimmable driver is a kind of equipment that changes the brightness, color or color temperature of LED light by external signals acting on the dimming module inside the led driver and then changing the output voltage and current. The Dimmable LED driver has different types.
