Hey there! As a supplier of 2835 620NM SMD LEDs, I often get asked about the constant - voltage driver for these little guys. So, I thought I'd write this blog to share what I know and help you understand this topic better.
First off, let's talk about what a 2835 620NM SMD LED is. The "2835" refers to the size of the LED package, which is 2.8mm by 3.5mm. It's a popular size because it's relatively small and can be used in a wide range of applications. The "620NM" indicates the wavelength of the light emitted by the LED. In this case, 620 nanometers falls in the red part of the visible light spectrum. These LEDs are commonly used in things like horticultural lighting, indicator lights, and some decorative lighting applications.
Now, let's dive into the constant - voltage driver. A constant - voltage driver is an essential component when it comes to powering 2835 620NM SMD LEDs. You see, LEDs are sensitive to changes in voltage. If the voltage supplied to them is too high, they can burn out; if it's too low, they won't emit light as brightly as they should. That's where the constant - voltage driver comes in.
The main job of a constant - voltage driver is to provide a stable and consistent voltage to the LEDs. It takes the input voltage (usually from a power source like a wall outlet) and converts it into a specific, steady voltage that the LEDs can handle. For 2835 620NM SMD LEDs, the typical operating voltage is around 2 - 3 volts, depending on the specific model and manufacturer.
There are a few key features to look for in a good constant - voltage driver for these LEDs. One important thing is efficiency. An efficient driver will convert the input power into usable power for the LEDs with minimal loss. This not only saves energy but also reduces heat generation, which can extend the lifespan of both the driver and the LEDs.
Another feature is reliability. You want a driver that can operate continuously without failing. Look for drivers with good quality components and proper protection mechanisms, such as over - voltage protection, over - current protection, and short - circuit protection. These protections can prevent damage to the LEDs and the driver itself in case of any electrical glitches.
When choosing a constant - voltage driver, you also need to consider the power rating. The power rating of the driver should match the power requirements of your LED setup. To calculate the power requirements of your 2835 620NM SMD LEDs, you need to know the forward voltage (Vf) and the forward current (If) of each LED. Multiply the Vf by the If to get the power consumption of a single LED. Then, multiply that by the number of LEDs in your circuit to get the total power requirement. Make sure to choose a driver with a power rating that is slightly higher than your total LED power requirement to allow for some margin of safety.
Let's talk a bit about the different types of constant - voltage drivers available. There are linear drivers and switching drivers. Linear drivers are relatively simple and inexpensive. They work by dissipating the excess voltage as heat. However, they are not very efficient, especially when there is a large difference between the input voltage and the output voltage.
Switching drivers, on the other hand, are more complex but much more efficient. They use a switching mechanism to convert the input voltage to the desired output voltage. This results in less power loss and less heat generation. Switching drivers are generally a better choice for larger LED installations or applications where energy efficiency is a priority.
