In the current world the use of electrical appliances and
electronics devices are essential for daily living. In such a case the power
consumption of these devices and appliances are the only disadvantage other
than their useful advantages. The power consumption is also considered in case
of lighting systems. In earlier days the incandescent bulbs were used which
usually produced heat from 90% of energy supplied to it and produced light from
the remaining left over energy, this feature turns them into a low efficient
bulb.
The fluorescent bulbs are efficient then the incandescent
bulbs but not much when compared to the latest invention the LEDs. The LEDs are
light emitting diodes which utilize the maximum energy and remain to be highly
efficient light source. The combination of these light emitting diodes will
constitute a LED bar light.
The light emitting diodes are called solid state devices
since they don't have the vacuum chamber as in case of the incandescent bulbs
and the fluorescent bulbs. The LEDs on their earlier days where capable of
emitting only RED light and where eventually used in lab equipments and later
used in electronic home appliances.
The LEDs became cheap and where available in all sorts of
devices later. The experiments on LED and its properties led to discovery of
variety of colors obtainable from them and then led to the invention of high
light intensity LEDs. These LEDs are known as the light bar LEDs.
These light emitting diodes because of their flexible nature
and high efficiency in energy usage have the use in variety of applications.
The applications include the street traffic signal lights, ambulance, indicator
lights etc. One of the major usages of high intensity light emitting diodes is
their use in torch lights. These LEDs are highly capable of emitting high
intensity light source when compared to its predecessors the incandescent
bulbs.
These LEDs in the torch lights are capable of working for
more than 50,000 hours. These high intensity LEDs are used in LED bar lights.
These LED bar lights are therefore highly capable of illuminating larger areas.
The neon light which were used of decorative purpose in the streets are
nowadays replaced by these LED bar lights since they very little energy
compared to large energy consuming neon lights.
The main advantage of these Light Emitting Diode lighting
bars is that they are cost efficient and energy efficient. These LED light bars
consume the least amount of power compared to its other competitors in market
like the incandescent and fluorescent bulbs. Hence they are energy efficient
and since they consume less energy they help us save a lot of money compared
making them cost efficient.
The only disadvantage of these LED light bars is their cost.
Since the solid state devices are not readily available and they have to
manufacture from various sources the cost of these devices is high. But since
it's just a single time investment it's not a big issue compared to its merits.
The LED light bars haven't found their place in the current society yet.
