The use of LEDs
as street lamps can be regarded as a new technology. People are starting to
recognize this light since the LED light is produced on a large scale. In fact
the LED lights are also preferred because the community has a big advantage for
the environment. So the city streets are now filled with LED street lights. However there may be some areas that do not use
them. In Indonesia, the government plans to change all street lights will be
replaced with LEDs. Moreover, some of the largest lighting companies such as
Philips and Panasonic began producing it.

The advantages
of LED street lights are
cost-effective and environmentally friendly electricity. This type of lamp
started receiving a lot of people because it is more durable when compared to
bulbs. Actually LEDs had long been found. You can find it when you turn on the
computer, speakers, televisions and other electronic furniture. When you turn
on the device, there is a small light as a 'ON' sign. The small light emitting
diode is familiar called LED. LED is a semiconductor that converts electrical
energy into light when an electric current is passed by.
The use of LED street lights is chosen because it
has the following advantages:
•
LED lives longer than the regular bulbs. It can
reach up to 30.000 hours
•
LED does not produce UV light, so it is not hot
•
LED’s light does not distort the colors
•
It has 80%-90% efficiency than the other light.
LED supports the low power supply voltage
•
It has not mercury (environmentally friendly)
•
It is small, so it is more practical
Disadvantages
Like other
product generally, LEDs have several shortcomings that still makes people to
use it. It seems that some of the following deficiencies also affect the
Government's consistent use of LED
street lights.
•
Its prices are too expensive
•
Light intensity is small,
•
Its influence affect the lifespan of LED lamp
However, the
weaknesses in the LED do not make a lot of parties including the government to
use the LED street lights. Because
of the effectiveness, the LED is superior to other lamps. Even the 8 watt LED
lamp will light up brighter than ordinary 20 watts bulbs or fluorescent lamp
power. It seems that plan of LED street lamp replacement is not just an issue.
Even, many countries have applied this kind of lamp for their street lamp.

ReplyDeleteThe power supply in an LED bulb has a full wave bridge rectifier and a small amount of filtering and a current regulator. If one half of the bridge rectifier is open or if the filter capacitor is open or missing there will be pulsating direct current feeding the LED’s in the bulb. The LED’s are connected in series and fed with a constant current by the regulator. If the pulsating DC goes to zero for more than a millisecond or two, you will notice flicker because the current regulator cannot compensate for zero and the LED’s will go dark for a few milliseconds during each cycle. led strip manufacturers
