Whats the difference between a clear LED and a diffused LED?

Not a whole lot


LED鈥檚 are available in a range of viewing angles. The bright ones typically have narrower beam width.


The wide angles ones are the ones with the diffuser; it helps to reduce the annoyance.


LED鈥檚 are monochromatic it means they emit only one color. This is what makes them annoying.


The diffuser reduces the luminous output to some extent.

The actual silicon (doped in various ways) produces a fairly narrow beam.





Clear LED can have can have a higher intensity in a narrower beam.

The end user has to view somewhere in that ~+/-15 degree perpendicular to the chip inside the plastic capsule. These were commonly used to illuminate the end of a light pipe or behind a silk screened icon in consumer electronics then diffused at the viewer end.





Diffused LED spread the beam out but absorb some of the output.

A much wider viewing angle is possible but you may not be able to notice it from a long distance. Often used in displays viewed up close.Whats the difference between a clear LED and a diffused LED?
A clear LED has a clear plastic that encapsoles the physical parts of the LED. A point source, it may radiate differently over a 360 degree radius. (2 pi) By making the plastic a diffuser, the pattern may be made more uniform.
Clear: you can see all inner features distinctly. When lit, you can see the glow at the internal junction.





Diffuse: the plastic is somewhat cloudy, and the whole surface glows.





Kind of like the difference between a frosted and an unfrosted incandescent bulb - the unfrosted, you can see the filament.
Light scatters in diffused LED.
