  • Wheel Size Vs Tyre Size: Which Tyre Size Best Or Suitable For Your Sport Rim Width? – Saiz Tayar Dan Rim Sesuai
  • LED TRAFFIC LIGHT VS HIGH POWER LED TRAFFIC LIGHT VS EKO STOPLIGHT/ TRAFFIC LIGHT VS SOLAR TRAFFIC LIGHT VS SAND GLASS TRAFFIC LIGHT

    Traffic lights, which may also be known as stoplights, traffic lamps, traffic signals and stop-and-go lights are signaling devices positioned at road intersections, pedestrian crossings and other locations to control competing flows of traffic. Traffic lights have been installed in most cities around the world. They assign the right of way to road users by the use of lights in standard colors (red – yellow – green), using a universal color code (and a precise sequence to enable comprehension by those who are color blind).

    Typically traffic lights consist of a set of three colored lights:
    RED > STOP
    AMBER/YELLOW > PREPARE TO STOP
    GREEN > GO

    But in Malaysia due to bad driving attitude of some Malaysians, it will be quite different, Green is the same – that means “Go”, but amber and red are different. Amber means “Go like hell” and red means “Stop if there is traffic coming in the other direction or if there is a policeman on the corner”. Otherwise red means the same as green. Note that for buses, red lights do not take effect until five seconds after the light has changed.Do you agree?

    LED TRAFFIC LIGHT

    The new traffic lights you are seeing are made out of arrays of light emitting diodes (LEDs). These are tiny, purely electronic lights that are extremely energy efficient and have a very long life. Each LED is about the size of a pencil eraser, so hundreds of them are used together in an array. The LEDs are replacing the old-style incandescent halogen bulbs rated at between 50 and 150 watts.

    LED Traffic Light three big advantages:

    LEDs are brighter. The LED arrays fill the entire “hole” and have equal brightness across the entire surface, making them brighter overall.
    LED bulbs last for years, while halogen bulbs last for months. Replacing bulbs costs money for the trucks and people who do the work, and it also ties up traffic. Increasing the replacement interval can save a city big dollars.
    LED bulbs save a lot of energy.

    The energy savings of LED lights can be huge. Assume that a traffic light uses 100-watt bulbs today. The light is on 24 hours a day, so it uses 2.4 kilowatt-hours per day. If you assume power costs 8 cents per kilowatt-hour, it means that one traffic signal costs about 20 cents a day to operate, or about RM73 per year. There are perhaps eight signals per intersection, so that’s almost RM600 per year in power per intersection. A big city has thousands of intersections, so it can cost millions of dollars just to power all the traffic lights. LED bulbs might consume 15 or 20 watts instead of 100, so the power consumption drops by a factor of five or six. A city can easily save a million Ringgits a year by replacing all of the bulbs with LED units.

    ======================

    HIGH POWER LED TRAFFIC LIGHT

    High Power LED traffic signal will soon be replacing current LED traffic light.

    High Power LED traffic light provides the following advantages:

    No Black Spot > Unlike normal LED traffic signal, High Power traffic signal is covered by dual diffuse lenses. Thus even some LED was burnt, we can’t see any black spot on it.Energy Saving > Only 4-18 pcs High Power LED is used with our High Power LED traffic signal, thus providing better energy saving.
    Even Brightness > Our High Power LED traffic signal consist of dual lense that provide uniform lighting output.
    Retrofit > High Power LED traffic signal is completely retrofit into existing traffic signal housing.
    Lifespan > LED traffic signal has longer lifespan compare to halogen bulb.Provides Up to 3 years No Failure Warranty.Thus reduce maintenance cost.

    ======================

    EKO STOPLIGHT/ TRAFFIC LIGHT

    Damjan Stankovi? has designed a useful and clever concept called the Eko stoplight. It is a traffic light that comes with a timer, counting down the time you have before the green light. So if there’s long wait you can turn off the engine and turn back on when it’s about time.

    ======================

    SOLAR TRAFFIC LIGHT

    The Solar Traffic Light is designed by three designers Cheng-Tsung Feng, Yao-Chieh Lin and Bo-Jin Wang. The Traffic Light is equipped with Discolor LED (Light Emitting Diode) technology, hosting all the three colors of the lights (Red, Amber and Green) within a single unit. It is powered by its own solar panel that is built on top of it.

    ======================

    SAND GLASS TRAFFIC LIGHT

    What you’re looking at above is the Sand Glass LED traffic light concept from designer Thanva Tivawong.
