Round Type Through Hole High Brightness 620-630nm Red 3mm Diffused LED

Description:

LEDs are available in a range of colours - red, green, orange, yellow, blue and even white. There are even more exotic colours such as turquoise, violet and ultra-violet but they are considerably more expensive than common reds & greens.

The housing of the LED is made from an epoxy resin. Whilst it has to be translucent to allow the light out, there are different types of translucency available. The most common is "diffuse" - this is the same colour as the device and looks cloudy, to help diffuse the light evenly from the speck of semiconductor (which would only be about 1mm square) into the top portion of the housing.

Next there are what are generally termed clear coloured (e.g. clear red). These have the colour but not the cloudiness of the diffuse types, and tend to be used for higher brightness devices. The tradeoff is they do not have such a wide viewing angle - if you're not looking almost head on, you'll not see much at all.

Finally there are totally transparent ones known as "water clear". Again the viewing angle is narrow, but these offer the greatest contrast between 'on' and 'off' especially in bright conditions.

Water-clear LED lenses are composed of a transparent plastic. They are a little brighter because the transparency of the lens does not allow for absorption or dispersion of the light. This type of lens is a light straightening lens, and is used in devices such as flashlights or traffic lights.

White diffused LED lenses are opaque, in that they are cloudy. These types of lenses act to disperse the light, thus making it possible to view from all sides. As opposed to the water-clear LED, the opaque lens absorbs the light and spreads it over a greater viewing angle. Common uses for white diffused lenses are for power and ready status.

Color diffused LED lenses are essentially the same as white diffused lenses, except they are tinted in a specific color. Therefore, colored lenses also spread the light consistently on all sides, but in a colored light.
