Hey there! As a supplier of 2mm Dip LEDs, I often get asked about the luminous intensity of these little light - emitting wonders. So, let's dive right in and break it down.
First off, what exactly is luminous intensity? Well, in simple terms, it's a measure of the amount of light a source emits in a particular direction. It's measured in candelas (cd). For a 2mm Dip LED, the luminous intensity can vary quite a bit depending on a bunch of factors.
One of the main factors is the color of the LED. Different colors have different characteristics when it comes to light emission. For instance, 2mm White LED typically have a wide range of luminous intensities. White LEDs are often used in applications where general illumination is needed, like in small indicator lights or backlighting. The luminous intensity of a 2mm white Dip LED can range from around 10 millicandelas (mcd) to several hundred mcd. This variation depends on the quality of the semiconductor materials used, the manufacturing process, and the specific design of the LED.
On the other hand, 2mm Blue Tower Led have their own unique luminous intensity profile. Blue LEDs are known for their high - energy light emission. They usually have a relatively high luminous intensity compared to some other colors. A 2mm blue tower LED might have a luminous intensity starting from around 50 mcd and can go up to a few thousand mcd in high - performance models. This high intensity makes them great for applications such as signage, where they need to stand out even in well - lit environments.
Now, let's talk about the 1.8mm tower top led. Although it's slightly different in size, it's still related to our 2mm Dip LED family. Amber LEDs, like the ones in the 1.8mm tower top design, have a warm - colored light. Their luminous intensity is often in the range of 20 - 200 mcd. This makes them suitable for applications where a softer, more attention - grabbing light is required, such as in automotive dashboard indicators or small decorative lighting.
Another factor that affects the luminous intensity of a 2mm Dip LED is the forward current. The forward current is the amount of electrical current flowing through the LED. Generally, as the forward current increases, the luminous intensity also increases. However, there's a limit to how much current you can apply. Applying too much current can cause the LED to overheat, which not only reduces its lifespan but can also lead to a decrease in luminous intensity over time. Most 2mm Dip LEDs are designed to operate at a forward current of around 20 milliamperes (mA), but this can vary depending on the specific model.
The viewing angle of the LED also plays a role in the perceived luminous intensity. LEDs with a narrow viewing angle will appear brighter in the direction they're pointed because the light is concentrated in a smaller area. In contrast, LEDs with a wide viewing angle spread the light over a larger area, so the perceived brightness in any one direction is lower. For 2mm Dip LEDs, the viewing angle can range from 15 degrees (narrow) to 120 degrees (wide).
When it comes to choosing the right 2mm Dip LED for your project, understanding the luminous intensity is crucial. If you're working on a project that requires a bright, focused light, like a laser - pointer - style application, you'll want to choose an LED with a high luminous intensity and a narrow viewing angle. On the other hand, if you need a more diffused light for general illumination, an LED with a lower luminous intensity and a wide viewing angle might be the way to go.
As a supplier, I've seen all sorts of projects that use 2mm Dip LEDs. From DIY electronics enthusiasts creating their own gadgets to large - scale manufacturers producing consumer electronics. The versatility of these LEDs is really amazing. They're small, energy - efficient, and come in a wide range of colors and luminous intensities.
