How to choose LED Driver?

If you have an LED light, you may need an LED drive power supply to ensure that the LED operates normally. Do you feel annoyed because you don't know how to choose a led drive power supply? Below, we will discuss how to choose LED drive power from five aspects, I believe it can help you.
Voltage and current
First, consider whether the voltage and current of your lamp are compatible with the output voltage and current of the LED driver. Before purchasing the LED drive power supply, check the specifications of your LED products, refer to the specification requ irements, and purchase the LED drive power supply. If your LED light needs 12 volts to work, you need an LED drive power supply with an output voltage of 12 volts. At the same time, it is also necessary to refer to the voltage supply of the LED lamp. Different countries have different power supply standards, and there are differences in the power supply standards for households, businesses and enterprises. If you are not sure, it is best to consult an electrician. An LED lamp is used in 220 volt alternating current, it needs an input voltage range including 220 volt LED driving power.
When choosing a driving power source for a constant current LED, the output current of the LED must also be considered to ensure that the current requirements of the LED lamp are met. If the LEDs are connected in parallel, add all the current values while keeping the voltage range stable. If the LEDs are used in series, add all the voltage values, but keep the current of a single LED the same. In short, in order to ensure that the LED you buy can be used stably, the output voltage, output current and input voltage of the LED drive power supply must be within the specified range, that is, determine the power output. When you buy the LED drive power supply, provide the LED lamp parameters as detailed as possible, so that customer service can provide you with fast and accurate service.

Dimming
Constant current and constant voltage LED drive power supply can have dimming function. If your LEDs are dimmable and you want to change their brightness, choose a dimmable LED driver. The specifications of the LED drive power supply will list whether it is dimmable and the type of dimming. If dimming is not mentioned in the manual, then the product is not dimmable. The dimming types generally include SCR dimming, 0-10V dimming, PWM dimming, resistance dimming, and Dali dimming. These dimmable types have been introduced in previous articles.

Size
When choosing the LED driver power supply, pay attention to the size of the housing or installation area of the LED lamp. If you want to install an LED driver inside the product, the driver must be small enough to fit the internal space of the LED light. Similarly, if the driver or power supply is used outside the product enclosure, it should fit the installation area. Our company can provide various sizes of LED drive power or customized mold opening services to meet your needs.

Efficiency
Efficiency is the ratio of input active power to output active power. LED is an energy-saving product, so the efficiency of the drive power supply is higher. The efficiency of the power supply is high, 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 the LED. The efficiency of general LED drive power is about 80%-90% or even higher.

Safety
CE certification
CE certification refers to the basic safety requirements for products that do not endanger the safety of humans, animals and goods. The CE mark is a safety conformity mark. It is a mark that represents that the product has complied with European safety/health/environmental protection/sanitation standards and directives.
IP rating
The IP rating is the protection rating for the enclosure of electrical equipment against the intrusion of foreign objects.

digital	First digit-dustproof	First digit-waterproof
0	No protection	No protection
1	It can resist solid materials over 50mm.	Can withstand vertical drops of water
2	It can resist solid substances with a diameter exceeding 12mm and a length not exceeding 80mm	Can withstand the direct spray of water spray at a vertical angle of 15°
3	It can resist solid materials with a diameter of more than 2.5mm.	Can withstand the direct spray of spray at a vertical angle of 60°
4	It can resist solid materials with a diameter of more than 1.0mm.	Can withstand spray from any direction-allowing limited entry
