1. |
To save energy = to decrease CO2 emission |
| |
· |
Mercury vapor bulbs and high pressure sodium bulbs light with
360° viewing angle, so over 50% light output is wasted. |
| |
· |
LED lighting is directional with high light
output utilization rate.(A customized lens can even increase the
utilization rate) |
| |
· |
With the same illumination, LED light saves more than 50%~80%
energy than tradition light. |
| |
|
|
| |
2. |
To Decrease the consumption
of Earth Resources. |
| |
· |
Copper mines resource are decreasing , so the price of copper is
increasing, |
| |
· |
Using LED light saves more than 50% of energy, so using LED can
drastically decrease the use of copper in wires and the use of
energy. |
| |
· |
LED light has longer life span, so using LED light means
decreasing the consumption of manufacturing light bulb
resources. |
| |
|
|
| |
3. |
To Decrease Maintenance Cost |
| |
· |
LED technology is improving fast, and the life cycle of LED is 3
times longer than traditional lights. |
| |
· |
Using LED light can drastically reduce the maintenance fee, such
as the frequency of changing bulbs, consumption of materials and
labor cost. |
| |
· |
Changing Traffic light less frequently also reduced the hassles
of traffic problems caused by changing light bulbs. |
| |

4. |
To Protect Environment & to Reduce Light Pollution |
| |
· |
LED lighting consumes low energy, reduces CO2 emission, and
improves controlling green-housed effect. |
| |
· |
LED street lighting is mercury-free, so will not cause
heavy-metal pollution. |
| |
· |
LED street lighting is directional, and will only light on to
roads, instead of plants in the farms that are close to the
street lights. |
| |
· |
Lighting at night no to plants will confuse the biological clock
of them, and affect harvest timing. |
