LED Traffic Lights

1. Low power consumption
Compared to traditional lamp-house(such as incandescence light ), the lamp-house with LED have a lower power cost, and save energy sources.
2. Long longevity
LED'S longevity can reach to 50, 000 hours, Mwhich is 25 times than incandescence light. So it can save much fee of maintenance.
3. Steady signal colors
LED lamp-house emission homochromy light which the signal demand, and the lens don't need to add colors, so it will not have the limitation because of the fading lens.
4. Abstain artificial display
In order to have a better light display, the traditional lamp-house(such as incandescence light) need collocate glisten cup, and the lens need to add colors, so it may result in artificial display. And even misguiding the traffic actor to result in traffic accident. But the LED traffic signal light have not these abuses.

B: LED traffic signal light'S Technical capability

1. Work voltage: AC220V+10%(-10%) .
2. Power: Less than 15W
3. Luminance and angle accord to some rules of GB14887 .

4. Work temperature: Can work well during +80degrees to -40degrees
5. Wet-hot capability: Can work well less than 95% of the relative humidity
6. Electric security capability:
01. Insulated resistance: The insulated resistance is more than 10 M? between electrification parts and cover body.
02. Insulated intensity: It will not happen flashover and hit-broken when there load 1440V between electrification parts and cover body.

C. LED traffic signal light's characteristic

1. Apply the Gather-carbonic-acid-ester that is produced by Germany Baier company and America GE Company as crust, which has 10 years longevity and fetch up the flaws that the metal crust is easy corrodent by salt-fog.

2. Apply the Super high-luminance LED with four elements which are special in traffic signal light, reliable qulity, and have more than 50, 000 hours longevity.
3. Special circuit design. It apply Switch electrical source way for impulse power supply aiming to different lamp models, which is better and more stabilization than resistance way and the transformer way.
4. Special construction design, reliable intensity, beautiful figure, original unlocking equipment. Install simply, Maintenance convenient, and double airproof function, which can reach IP54 grade for dustproof and waterproof.
5. Legerity configuration, which choose the high grade plastic material and the weight is less than half of the metal crust lamp. It's safety and reliable to install in the cantalever.

6. Strict quality management, passing the ISO9001 international authentication. Rigorous demand to select material, there is strict quality controlling with all the material stock channel. Controlling a lesser alteration range among electron parts' technic parameter, and make sure there are more than one week's aging test before the products leave factory.
7. Series design and produce, holding several items of patents. Having variety of products, combination agility and convenien
