The Advantages of LED Traffic Lights

Currently, the super bright LED bulbs have replaced incandescent lamps as
traffic lights, warning lights, sign lights all over the world. Compared with
incandescent lamps, LED traffic lightshave the advantages of low power
consumption, long life span, and higher brightness, which makes them an ideal
light source for traffic signal lighting.

1. Good visibility:

LED traffic lights in continuous light, rain, dust and other harsh weather
conditions, can still maintain good visibility and performance. LED emit
monochromatic light, which does not require the use of color film to produce
red, yellow, green color signal; besides, the light emitted by LED has a
certain divergence angle and directivity , which can be used instead of the
traditional signal aspheric mirrors. These features of LED lights solve the
phantom (known as false shown) and color film fading problems in traditional
non-LED traffic lights and improve the light efficiency.

2. Saving energy:

Lower consumption, as the biggest advantage of energy saving in LED light
source makes big sense in lighting applications. Compared to incandescent bulbs
which offer 80% of a heat loss, only 20% of a visible light, LED traffic signal
offers almost 100% LED excitation energy as visible light.

3. Low thermal energy:

LED is driven by electrical energy directly into light, the heat generated is
very low, almost no heat. The cooled surface of LED traffic signal obtains a
longer life span and can protect people to avoid burns in maintenance.

4. Long life span:

Sometimes in freezing winter and sometimes in sultry summer, sometimes in sunny
days and sometimes in rainy days, the working environment for traffic lights is
relatively harsh, thus traffic lights has higher requirement for stability.
General lights with incandescent bulbs have an average life expectancy of 1,000
hours, while halogen light bulb have 2,000 hours, so the resulting maintenance
costs are high. LED traffic lights lifespan is about 80,000 hours and do not
suffer from damages caused by filament shocks or glass broken problems.

5. Fast response:

LED traffic lights response faster than halogen bulbs, therefore reducing
traffic accidents significantly.

Traffic signal lights play an important role in urban traffic, and a large
number of old or dead traffic lights need to be replaced or updated every year,
thus leading to a relatively large market. After all, high profits are
conducive to the development of manufactures and designers companies, and can
also stimulate the entire LED industry.
