Many lights, indoor lights, outdoor
lights which are now and gradually replaced by LED lights, Streetlights is an indispensable
luminair in public lighting, with streetlights replaced by LED, we can greatly
save the electricity for public usage, which can be efficiently used to other
important areas.
Streetlight is an important part of
city’s illumination; traditional streetlight using HPSL (high pressure sodium
lamp) which beams 360°caused a great waste of energy by its waste of light. Nowadays,
the global environment is deteriorating, every country are developing clean
energy, the development of national economy prominent conflict between energy
supply and demand. The problem of electricity power shortage should be solved. High
efficient, energy saving, long lifespan, high color rendering index, and
environmental friendly LED streetlights are important replacement of
traditional HPSL, and significant role of modern metropolitan’s illumination.
Illumination is closely related to
people’s life, LED streetlights benefit people with its directional lighting,
low power consummation, high driving performance, prompt response, high shock
resistance capability, long using life ,green and environmental friendly cha.
It becomes the most suitable choice to better road and street illumination
conditions.
Below are some points which we normally
think LED light is better than other Lights:
1, the intrinsic characteristic of LED
streetlight—light beamed in a single direction, no diffusion and efficient.
.
2, specialized optical treatment
put the light to the targeted area, in a further way improved the light
efficiency and energy saving.
3, when we talk about the LED, the chip
should be mentioned. This is the most important part because without it the led
street light can’t give out light. Not to mention the theorized value of
250lm/w, we talk about the actual lumen, which calculates the light the LED
give out. Most factory will use110-130Lm/w, which belongs to better quality,
but it’s the one normal led street light will use.LED light beat the high
pressure sodium lamp on brightness, the disadvantage of HPSL is that the more
light needs more power.
3,LED can have a higher color rendering
index of 75 above, I said 75,because normal chips in the markets are in this
level, of cause, better chips will beat 80 above according different
manufacturers. The high CRI are an apparent advantage comparing with HPSL’
23ra, furthermore, LED can save 20% electricity to reach the same brightness as
HPSL’s.
4, luminous attenuation is an important
factor should be considered while choosing luminaire. Why some lamps give out lesser
and lesser light while you continue using? Because of its high light
attenuation, But for led, only 3‰ a year, 100times lower than HPSL.
5, Powered by low voltage DC current,
comparing with traditional high voltage AC current,Led Light is safe for using.
6, How long can you use traditional
incandescent lamp, fluorescent tubes? Maybe 4 or 5 years it will break down. But,
this not for LED,LED have an average lifespan of 50000hours,just calculating by
6 hours a day, it can use 20 years above.
7, LED light can be as easy as
traditional light to be installed on a pole, many manufacturers are using
screws, supporters, and something else, which are simple and easy to be fixed
safely without much effort.
8, Choosing a reliable
manufacturer and ask them to use high quality electrical components and add
independent over-current protection. Because, even the best light if you do not
fill the components good and right, it will fail. This happens on every kinds
lights, machines, LED have no exception. You will find LED light is very
reliable, when you get the good quality ones. We just consider LED lights are
more reliable than other lights based on they use same quality components.
9, LED do not contain mercury,
will not pollute our environment. But, HPSL have, it’s time to replace old HPSL
to LED for a better environment.
10, which good quality components
produced by good manufacturer, LED streetlight almost have zero maintenance
rate. Maybe, I should say directly LED streetlight have zero maintenance rate, because
every kinds goods if need to be used long, should have good quality. That’s the
common sense.
Some manufacturers produce LED
streetlights with a very cheap price, it’s useless to buy those products, because
they produce that for making money, not for the purpose of producing a real
piece of goods.
LED lights, especially LED streetlights should
always keep mentioned its quality standard. I know some people would say, even
the worst equipped led street light will use longer than traditional HPSL. I
will not doubt it; just think that LED should give out its real power, don’t make
its luster fade in its heyday.
