Snow Scoop on traffic signal tunnel visors

　　 Presumably ,a snow-covered red light is a key factor in a fatal auto accident.BBM traffic signal lamps are studying the issues that potential of snow blocks drivers’ view as LEDs used in traffic signals don’t radiate enough heat to melt snow accumulating in the sun visor that surrounds each signal light ,and trying to solve the problem .

　　 They put forward idea of designing more scientific and powerful led traffic light visor which will effectively prevent snow’s adhesion and accumulation, making low energy of led traffic signal lamps is no longer a disadvantage.

   In fact,the snowy LED issue is not a new problem.The Colorado Department of Transportation realized the potential danger five years ago, and sought a solution. Such transportation departments are reluctant to give up the cost savings associated with LED traffic lights, and a simple Snow Scoop from McCain Inc (see below) can inexpensively mitigate the problem.
　　
   LEDs offer significant savings to transportation departments. According to the research of BBM led traffic ligts ,a 69W incandescent bulb is replaced by an LED version that dissipates only 11W – an 84% savings. Early on, LED signal heads cost two or three times more that the traditional incandescent heads. Today the premium is in the 60 to 80% range. But the LED signal heads last ten times longer so the savings are substantial when you add up energy cost, the cost of the signal heads, and the labor required replacing failed signal heads.
　　

   The city saves about $100,000 per year on electricity powering 4,000 LED-based signals. Clearly, the city would like to stick with LEDs and preserve that savings. The motivation has been sufficiently strong that transportation workers in Iowa have manually tapped signals to release trapped snow when conditions were problematic.
　　
   Colorado, meanwhile has satisfactorily deployed the aforementioned Snow Scoop Tunnel Visor. McCain VP of Manufacturing Greg Johnson describes the visor "like an air scoop on a hot rod." According to Johnson, the Snow Scoop design utilizes the same force – wind – that causes the problem in the first place. It's wind that blows snow into the visor. Johnson stated, "With snow there is usually wind and we figured that we could use a louver to allow the wind to clear the snow from the visor." The scoop in the design extends upward at an angle from the cylindrical visor and drives wind through a louver slot underneath the scoop on the top of the visor. The cylindrical visor also has a lengthwise slot at the bottom of the design that allows the snow to fall out.
　　

  The image at left shows the air scoop and the louver slot through whic wind enters the visor, as well as the slot at the bottom where snow exits.And It turns out that the new visor offers a very economical solution to the problem。

Will Internet Of Things Bringing An End To Traffic Sign Light?

　　 What would the transportation be like when car are becoming more and more of automated driving which controlled by computer according to vehicle and road status analyzed in the cloud?
　　
    The imagination and prediction of the transportation in future of Traffic lights Research Department of BBM Technology Co. Ltd will provides us a glimpse of what transportation might look like in the future .
　　
    BBM, a professional LED Traffic signal lights manufacturer, supplier and exporter devoted to  developing, manufacturing and marketing believes that the innovative company not only  need excellent professional knowledge, but also need innovative thinking, bold vision and close attention of industry trends.
　　

    By all indications ,the transportation industry tends to be intelligent,and Internet of things will change our lives.The emergence of automatic driving technology will certainly led to the progress and evolution of transportation as the coevolutionary mechanisms between them.
　　
    Once the Internet of things beginning to be deployed and the car was connected to the Internet,our car will be in control of the computer .Hence,  will we not need led traffic signal light any longer? Or more intelligent led traffic sign light will be in need? Or  Internet of things will bringing an end to traffic sign light?
　　
    In the future,traffic flow is dominated and decided by computer calculation instead of default behavior in the human brain:there exist a control center in charge of the transportation across the country,which make the traffic rule ,Red for stop and green for go ,that we have know when we were in our childhood inapplicable. The speed and direction of all vehicles will be determined by the computing center, and the concept of traffic will turn into a constant flow the rate of which exceed the expectations of human drivers. Generally the future transportation will be a system engineering involving people and cars,cars and roads,roads and environment and the user experience .
　　

    Recently Austin's artificial intelligence laboratory of University of Texas is researching in autonomous intersection control (AIM) in the guidance of this concept. Self driving cars aren't going to stop at a red traffic light but to adjust the speed to control the time of passing through intersections in real time.
　　
    This project is not only aimed at eliminate the waiting time of the intersection,but also reducing fuel consumption and emissions. "Many of the emissions and fuel consumption are caused by the acceleration, and our system will allow the car running at a more constant speed.Although the AIM system is complex, it is superior to the traffic warning light for guarantee of the safety of the intersection.”Project director Stone Peter said.
　　
    “There are thirty percent of the fatal traffic accident  taking place at the intersection ,which proves it is dangerous when driving at the intersection. In condition of automated driving,the situation will be greatly improved even keeping all cars passing through the intersection at the same time.
　　

     Meanwhile , a new idea coming with the Internet of Vehicles interests us.What can people do in the car after freeing their hands? We believe what they could do will not be confined to sleeping or texting .
　　
     In future inside the cars will be full of diverse interactive devices for recreation and entertainment.what’s more,the  pressure sensing touch technology will also be applied to the automotive sector.,which will open up a whole new area of human computer interaction.
　　

     This Big Data has been the top words between traditional industry and manufacturing giant .They provide partners and consumers with images of the future and various possibilities in the world of big data . You can view this as the marketing gimmick,but you have to admit the fact that Big Data and Internet are providing power and tools for industrial giants  in an unprecedented way.

International Trade Experts To Decipher How To Choose Suppliers of Traffic lights

　　 International trade is more intricate and complex than domestic trade, in addition ,the asymmetry of information makes oversea buyer of led traffic signal light invest a serious mount of time and effort to gather information and find out the optimal suppliers.What’s worse ,once you make the wrong purchasing decisions you may suffer loss more than money,especially when the traffic signals light are applied to municipal projects .
　
   Next, the international trade experts will give you a detailed analysis about how to choose the high quality suppliers of led traffic sign light.
　　

   First let’s analyze the demand of oversea buyer in international trade.
　　
   As an overseas traffic light buyers, they prefer to go straight to cooperate with manufacturer to avoid intermediate agencies and extra fees.The advantage of having technical resources allow the manufacturer to make technical improvement and upgrading in time according to your customer's need. Meanwhile the manufacturer can directly control the production cycle and costs. In conclusion all this means that the manufacturer can provide a better price and service.
　　
  Quality is always the first especially in Western Europe and the United States.Due to the contract culture and rigorous legal system of Europe, traffic lamp of poor quality cannot be accepted by the market.Once a problem occurs, the products will be be unconditional recalled, and the sellers have to pay an amount of compensation. So the quality for Europe and the United States market and buyers is the core and soul.
　　
  Naturally there is another questions followed : what kind of traffic signals light manufacturers will be able to ensure product quality?
　　
   First of all ,examine manufacturers' qualifications and background of exporting.
　　

   You’d better check the status of the supplier's credit and enterprise qualifications,such as national high-tech enterprise certification. Next make sure it is a professional traffic signal lamp manufacturers . Do not blindly trust some large enterprises which Scope of business cover a wide range not only including led traffic signal lamp, but also poles, monitoring, electronic police... This companies may be either integrators or shell companies .
　　
   Secondly, only with good certification standards, management systems, production processes, as well as inspection mechanisms can manufacturer ensure the quality.
　　
   Traffic signals light exported to foreign country need to achieve the quality inspection and provide a test report of the relevant country.As regional standards are different in different country, the requirements of the test report is not the same. Based on this,to confirm how many markets manufacturer has entered and its sales record in the relevant target market is an important aspect for overseas buyers to evaluating the providers .Sales record in the target market is a valid certificate of product quality, production process, applicable standards, trademarks and brand access,and so on.
　　

   Take BBM Technology Co., Ltd.in Shenzhen which has been enjoying a good reputation as professional intelligent traffic lights production for example.BBM have been certified as 'High Tech. Enterprise’ and all of their products are approved with kinds of quality standards such as RoHS, CE, FCC and IP65 TUV, ISO9001-2008 and so on.Relying on excellent product quality and excellent after-sales service,their business coverage European and American regions, with traffic signals light exporting to all over the world.
　　
  Inspection of manufacturer's production equipment and production process is necessary. Take wave soldering for example, in addition to the brand which will lead to product differentiation, the maximum diameter of the PCB supported by wave soldering is also an impact factor. The price of wave soldering supported 400mm PCB is 5-10 million more than conventional size. In addition, consumption of tin used to operates the wave soldering is also more than conventional one. Some enterprises in order to save costs buy a can in wave soldering with diameter of 300, and then accompany a hand Baptist tin stoves, tin is not large, 400 a smooth lamp they tend to adopt leaching first half, and then dip the other half of the processing, product quality greatly reduced.
　　

  Thirdly, investigate whether the traffic signs light manufacturers have the potential to provide large-scale products.Export volume and sales of the manufacturer objectively represent the value of its products how much, how wide range of consumer products, as well as the potential market can be opened up how deep. In addition, overseas grass dog is very clear that the supplier can not position its production. If the production scale is small, it will be unable to meet the needs of orders. Once the progress of orders for other buyers to catch up with the situation, it will delay the delivery period. This is not acceptable to most buyers. So we should choose a traffic light manufacturer with the capacity of mass production to maintain the stability and reliability of the supply chain.
