Ninth Elements To Give You A Quick Understanding Of Led Traffic Light

　　Once you grasp the key points ,many knotty problems will smoothly solved at any time. And element which is the basic unit of things is the the key point when you try to discover the law of their existence and movement .
　　

        The Brand Story Of BBM LED Traffic Light will takes a look at ninth elements of LED traffic signs light and give prominent annotations to help you get a quick understanding of led traffic signals light.
　　
        We are probably the first look at what are the main optical parameters:Color，LED Q.ty,Light Intensit，Wave Length，Power Factor，Viewing Angle,Power，Working Voltage，Housing Material.
　　
        Color : we know that the led traffic warning sign has three main colors: red, yellow and green. But the same color in fact vary widely. Take green for example, the green in my eyes may be not the green in your eyes. Green can be divided into pale green, kelly green and blue-green. In fact it can be further subdivided into more .
　　

        LED Q.ty: led quantity of led traffic signal module depends on the brightness of the single LED and the required total brightness of the led traffic signal light core. If the power of a single LED is smaller,more led will be needed to maintain the same brightness. Due to different technologies ,luminous efficiency of led is made to different.
　　
         Light Intensit: the brightness of the led traffic signal heads is very important. People can barely see clearly the led traffic signal light bulbs from a distance in the case of low brightness . It will be dangerous especially when the drivers in the distance can't see the led traffic signal and don’t have time to stop timely . And it will be dazzling if it is too bright. So the Intensit Light of led traffic signal heads is made to in accordance with visible distance .
　　
          Wave Length: As noted above in Color ,although people cannot be identical to the resolution of same color of light, the wavelengths of light can be determined. So we use Wave Length to identify the color.
　　
        Power Factor : power factor refers to the utilization of power, the lower the power factor , the more waste.
　　

        Viewing Angle : The light led emit possesses the directional properties with direction and angle. Viewing the image from the angle of view, the brightness will be satisfactory. If not, the brightness is not enough. The requirements of the Angle Viewing is different for different circumstances. Familiar examples are TV screens, computer monitors. Usually the larger Angle Viewing is, the better visual experience is. The larger the more expensive. It will be hard to see clearly the displaying content when viewing from the side.
　　
         Power: power is an important parameter of electrical equipment.The greater that of the power ,the more power consumption per unit time .
　　
         Working Voltage: the Working Voltage here is actually the rated voltage and is referred to standard working voltage of traffic signal module. Actual voltage is allowed fluctuates based on rated voltage in a range from 0-10％。Rated voltage may differ in different countries.
　　

          Housing Material:the housing of traffic sign light module has waterproofing and dustproof design requirements . The housing material can be classified into two types : Metal housing and nonmetallic housing .For example, in BBM the housing of 100mm led traffic signal is made of metal with painting/Aluminum/Stainless,while 200mm and 300mm traffic sign light are PC.
