SUPERNOVA
ELECTRONICS has introduced LED Based Road Traffic Signals
Lamp Head with viable optical intensity and minimum
power consumption. The AlInGap or InGaN technology of
LED emits bright and homogeneous light and is lifelong
(i.e. minimum life expectancy 11 years.) compare to
the conventional bulb. These lamps are benefited over
the conventional incandescent bulb signal lamps.

| LED
VS LIGHT BULBS |
|
Light
bulbs produce light over a wide spectrum with only a small
fraction, being visible light, the remainder is heat. This
inefficiency is eliminated with LED. LEDs produce monochrome
radiant in the visible spectrum, thus saving energy, which
would normally be used as heat.
|
|
| BENEFITS |
|
Major
problem in cities is electricity, & it's consumption.
Incandescent lamps have comparatively low life and need maintenance.
In some of the region power cuts are very frequent, which
leads to traffic jam as UPS (uninterrupted power supplies)
System / Solar based System are uneconomical for incandescent
Lamp Based Traffic Signals due to heavy electric consumption.
Where as, in LED Based Traffic Signals, it is possible and
very easy. Just by replacing bulbs from signal heads in the
crossing with SUPERNOVA LED kits. Now the total consumption
of crossing including SUPERNOVA traffic controller is less
than 0.2 KVA. From 2.0 KVA, thus Solar system's can be installed,
leading to continuous running of traffic signals in case of
no electricity.

| CIRCUIT
DESCRIPTION: |
|
LED's
are soldered in Glass Epoxy PCB. The LED's are operated in
a multi channel series/parallel matrix and are multiplexed
pulse operated at high frequency, high intensity and low duty
cycle to obtain maximum visible brightness at minimum POWER
consumption. The electronic circuit is built in the unit itself.
With tinted lens for protection in a Sealed beam type plastic
housing
|
| |
| How
does it work? |
|
The
SUPERNOVA LED KIT convinces with its bright and homogenous
light distribution. The LED's are evenly Arranged and grouped
in parallel chains on the LED board. In front of each led
plate there is lens that protects it from outside dust. The
light passes through the tinted or plain lens (as per customer
choice) front lens, which is precisely harmonized with the
LED Wavelength. This system creates a very homogeneous lit
aspect surface, and by using filter (optional) the individual
LED's are no longer Perceived as dots O/P intensity is reduced
by a fraction. Also comes with auto dimmer that further reduces
the power "consumption in night time (optional).

Features |
- Led
Traffic Signals USE 80~90 percent less electricity than
traditional incandescent traffic signals
- Led
Traffic Signals last 5~10 times longer. This longer life
translates into substantial maintenance
- Led
Traffic Signals increase visibility due to high light intensity
technology. (applying AIInGP or InGan Leds).
