How can you distinguish the cobweb or clear lens of traffic lights in NOBLE

There are two lens of most of NOBLE’s traffic lights. One is clear lens, other is cobweb lens. They are designed for the favor and demand of different countries.

Clear lens traffic lights only with one lens, it can be seen very clear inside the lights. The quantity of LEDs in clear lens traffic light is more that the cobweb lens traffic lights. So, its’ illumination brightness is great!

Cobweb lens traffic lights with two lenses, it’s unable to see LEDs inside the light head. Though the quantity of the cobweb light is less than clear lens, but its’ liminescence uniformity is better. And it looks more comfortable.

Both of them have their own advantages. You can select the different lenses of traffic lights according to your requirement.

Pedestrian push button for road crossing

The pedestrian controller is an independent intersection control system. It is mainly suitable for the arterial streets,and streets with fewer pedestrian.

This product is friendly designed, and has a broad market with social efficient. The whole system consists with one controller,two pedestrian buttons. The buttons are used in single lane,and menu 18 of “NOBLE” controller is for the button function. The controller is the hard core,when it run menu 18, can examine the pedestrian button signal, the vehicle traffic signals and the pedestrian traffic signals.

The pedestrian buttons are separately installed on the lampposts. This button is made of plastic with an indicating lamp,as well as a Fresnel lens.

The indicating lamp is usually on, when the pedestrian need to pass the street, he or she have to move in front of the Fresnel lens on the button within 80cm, until the body’s infrared be captured by the pyroelectric infrared sensor,in this case, the indicating lamp will be off once, means triggered successfully. If press the button,it will produce the same effect（triggered successfully）.

Once triggered successfully, if the vehicle traffic lights countdown below 38 seconds,it will turn yellow flashing immediately, run 3seconds; then turn red 30seconds,and the pedestrian light turn green,run 30 seconds to allow pedestrian pass through. If the vehicle traffic lights countdown above 38 seconds, it won’ t turn yellow flashing immediately until the time below 38 seconds,then it begin to turn yellow flashing 3seconds, red 30seconds, and then pedestrian light turn green,run 30seconds. If there is no triggered,the vehicle traffic lights will keep green all the time.

Blind clock for pedestrian walking safety

Blind clock sounds the walking alarm within green man signal period, the walking alarm points toward crosswalk.

Application: the blind clock is widely used crossing for people.

Easy design：Non destruction installation exist in the present traffic light system, it doesn’t need to change any line, and it keeps in line with the existed light casing .

Applicable object：any traffic light system in other city, and it improves the taste and the image of the city.

Product using：It can not only be regarded as accessory product with the manufacturer of traffic light, but also it can be installed directly to improve the exist function of the traffic light system

Voice customization：

Ø It can change the voice according to the change of the traffic light, it can be a word or some music；

Ø It can play two warning tone，red light and green light will play one song separately and circularly

Ø The key of voice can be adjusted，UP is defaulted as decrease, the indicator light will be off.（The below operation will be effective under the lift of the key）

（1）Pressing 4 to 5 seconds to change it into ADD, the key of indicator light will be ON. Under this situation short pressing means ADD the volume；

（2）Re-pressing 4 to 5 seconds then it change into decrease, the key of the indicator light will be off. Under this situation short pressing means decreasing the volume；

（3）Re-pressing 4 to 5 seconds and turning back to

Ø According to the different signal, it can change the warning tone automatically, when the green light is flashing(5s), the power will not be cut off.

Ø It supports two format MP3 and WAV

Ø The biggest volume is between 100-120DB

How to choose the best LED traffic light

Led traffic light is used on the intersection or other special site,used for indicating the driver and the pedestrian’s action. From the definition, we can see traffic lights quality and people's lives, travel are closely related, and safety issues related to drivers and pedestrians. So the LED traffic light quality is the most important factor for judging on whether the project good or not.

So how to choose the best quality of LED traffic light ? After several years experience, i have some advise as follows:

1. First , need assess traffic light factory qualifications.

In china, Traffic lights manufacturer concentrated in Guangdong, Jiangsu, Zhejiang, Shandong and Jiangxi area, truly qualified and scale manufacturers not more than 30. So, buy traffic lights, we can begin to look for from these places. In regard to quality, the ranking should be in front of factory in Shenzhen, especially while doing exit lighting manufacturers.

After find the factory, you should check the company information,such as whether the factory is special in led traffic light. Whether they have international test report. Whether they have export to your local city.

2. Second, need to know the quality and price

When looking at the factory, quality control need be critical, you can take a look at the electrostatic protection, employees are strictly required to wear an antistatic wrist strap, grounding equipment if there is work to do.

Further wave, angle cutter, grounding and inspection of the soldering iron should concern because of the machinery, equipment or tools to live a long time, and are prone to leaking, so the usual protection and detection work is important. Ask LED light intensity test equipment, high and low temperature aging equipment, salt spray test equipment, etc situation. Check the led brand hip, the pc housing IP rate, the warranty, the luminance. The watts etc.

Hope this can work for you!

Thanks!
