So, what is the "scoop" on LED signs?
A Light-Emitting Dode (LED) is a semiconductor diode device and it emits incoherent narrow-spectrum light when electrically biased in the forward direction.
So, what are some of the Advantages of using LEDs?
- LEDs are not sensitive to vibration and shocks, unlike incandescent and "discharge sources".
- LEDs have an extremely long life span: typically ten years, twice as long as the best fluorescent bulbs and twenty times longer than the best incandescent bulbs.
- LEDs DO NOT generate RF wavelengths that cause radio interference, or emit UV, Ultraviolet light (unless specified as a UV diode), so LEDs will not readily attract bugs and other insects.
- LEDs give off less heat than incandescent light bulbs with similar light output.
- LED signs use very little power (some of our LED signs specify 3w~7w max consumption).
So, what are the disadvantages of using LEDs?
In a LED sign with exposed LEDs, the sign will not be as bright when viewed from sharp side angles. LEDs are said to have a 30 degree viewing angle. Neon is equally bright when viewed from any angle, including side angles. When viewed from a direct "front view" and slight angles, LED signs are brighter than neon signs.
