The production of light with LEDs differs essentially
from
conventional light production technology in the following ways:
Advantages of LED
-
LEDs (Light-Emitting Diodes) have
resistance to shock and vibration.
-
LEDs last for up to 100,000 hrs.
LED required practically no maintenance.
-
LEDs is able to withstand input voltage
of + 25% without change in light output
-
The emitted light has no infrared
in UV components.
-
LEDs emit directional light, and
Intensity differs for different colors.
-
Luminous efficacy at present ranges
between 20-30 lm/W. Whereas light color are constant and independent
of temperature.
-
LEDs are instantaneously dimmable
and switchable in all frequencies.
-
LEDs can be combined in any form
of complex LED lamp configuration.
-
We can develop custom made lightly
through LED's through specific uses.
