Dimming LED Driver

When you try to purchase the LED Power Supply for your LED Lights, you’ve come across the terms constant current and constant voltage, if you are not a professional guy, you will no clue what those terms mean. In this post, we will clarify the confusion between constant current and constant voltage.

Constant Current Dimmable LED Driver

Constant Current LED Drivers

A Constant Current Driver that the output current is a steady value, which is always used to an LED or LED Array to maximize the lifespan because the LEDs have a power-limiting device in order to prevent LEDs from being overdriven. if the working current is not regulated, the brightness of LEDs can fluctuate and the life span will be shortened. the Constant Current LED Drivers always is used for the LED Lights that require a stable output current and operate within a range of voltages. if you are searching for a driver for the LED Strips with a constant current design or to replace the broken driver, it’s important to verify the output current and working voltage before you purchase one.

 

Constant Voltage Power Supplies

This type of Power Supply with a stable output voltage can be used to light up the LED Lights that have resistors or constant-current drivers. the products with these current-regulating devices might require working with a constant voltage power supply if the working voltage is not AC110V or AC220V, the LED Strips working always working in DC5V, DC12V or DC24V, you can not connect them to the public power system so that you need an AC DC converter that converts the voltage to the correct voltage. if the working voltage not matched, maybe the LED Lights will be damaged or shorten the lifespan.

 

if you have working voltage or working current issues with the LED Lights, please do not hesitate to contact us. we will be glad to help you to solve it asap.

12V Or 24V LED Lights? Which One Better For You?

As a newbie of LED Lights, when we browse the LED Light products on the internet, we find that the working voltage has 12VDC and 24VDC, so, what’s the difference between them? which one is better for me? today let’s check.

24V COB LED Strips

When we select the LED Lights we have many factors that need to think about, colors, waterproof or not, length or quantity, but about the working voltage, 12V or 24V, which one is better for us, we think it’s a question to most of the newbies. the answer is that comes to your project. we know the working voltage less than 36V is safe for humans and animals, so both working voltages are safe for your kids and pets. each voltage is better suited for specific applications, when we choose the working voltage for the LED Strips, the 24VDC is less susceptible to voltage drop, so that it can illuminate a strip more consistently over a greater distance, but for 12VDC, if the length over 5meters, the brightness will become weak from beginning to end slowly. so if you want to run a long length of the LED Strips, the 24V will be a better choice. also good for the high densities COB LED Strips.

12V LED Lights

On the other hand, if you want to run many LED Strips for your lighting project, we will recommend connecting the LED Strips to the Power Supply in parallel to avoid the voltage drop issue, or not connecting them one by one, whatever 12VDC or 24VDC LED Strips.

Before you try to light up the LED Lights, you should check carefully the working voltage of your LED Lights and accessories. if the unmatch working voltage maybe damage them. for example, if the LED Strips work in 24V, then the output voltage of the Power Supply should be 24V, if you want to add a Dimmer or Controller, the working voltage should be 24V.

the word “Max Run” means the maximum continuous length of LED Strips to a single Power Supply. the limit is not related to the maximum electrical power of the circuit, but instead is determined by establishing an acceptable amount of voltage drop, it depends on the number of LEDs and working voltage. the additional power suppliers or amplifiers mounted mid-run can drastically increase the run length, because the extra power inputs spread across the run help to decrease voltage drop. for some high-density Addressable LED Strips, we will recommend adding the same voltage every 5 meters to avoid the voltage drop issue.
