What do we know about
LED and what are its benefits?
lights have 10 times higher efficiency (luminosity/output) than light bulbs and
two times higher efficiency than fluor tubes (the most advanced ones over 100
lm/W) which is particulary effective in the devices supplied by batteries or energy-efficient
deliver light in a required colour without using complicated colour filters
- A LED
light cover can be designed to focus light to a certain spot. Light bulbs and
fluorescent tubes do usually need outer optical scheme to focus light.
the facilities where light dimming is needed, LED lights stay the same colour
after the power supply has been lowered, unlike classic light bulbs which give
off a slighly more yellow light after dimmed.
resistant to tremors and vibrations
- Is resistant
to cold weathers
ideal to make use of at those facilities where lights are turned on and off
frequently unlike regular light bulbs especially flood lights which are prone
to explosion when turned on and off too often. Fluor tubes are even more
sensitive to this which can lead to overheating of one of the filaments
benefits from its lifespan are, as argued by LED manufacturers, between
100 000 and 1 000 000 hours (doesn´t apply to high-power LED
whose values drop considerably). The lifespan of fluor tubes and light bulbs is
from 6 000 to 12 000 hours and 1 000 to 2 000 respectively.
often seen cause of failure of LED lights is a steady decrease in brightness
unlike light bulbs which over time are subject to a filament snap.
only takes a short while for the light to go on. A typical LED indicator light
starts glowing in the time frame of microseconds. The time needed for LED
lights to go on especially at telecommunication facilities is even shorter.
LED lights are conveniently small and can be planted onto printed circuit
not contain mercury (unlike lamps).
