2 LED Traffic Signals Best Alternative Up Until Now LED (Light Emitting Diode) traffic signals are an effective, efficient and safe alternative to traditional incandescent signals. Effective Energy Saving LED traffic signals use 80 to 90 percent less energy and last 5 to 10 times longer than the traditional incandescent bulbs. Typical Signal Wattages Signal Incan. LED Savings 12 Red 135 W 10 W 93% 8 Green 69 W 9 W 87% Pedestrian 69 W 7 W 90% Maintenance Cost Saving Due to the extended lifetime of LED signals, re-lamping can be conducted every five years, instead of every year. Increased replacement interval substantially reduces the maintenance costs and potential safety hazards for maintenance personnel. Enhanced Safety LED traffic signals are brighter, as the LED arrays fill the entire hole and have equal brightness across the entire surface. LED signals are very unlikely to fail all at once as they are comprised of many individual LEDs. (Conventional incandescent signals often fail without warning, resulting in intersections that can be hazardous for drivers, pedestrians and maintenance workers alike.) LED traffic signals can use a battery backup during power outages, providing additional safety. Hundreds of localities throughout the United States and Canada replaced their traffic lights to LED. Some of the success stories are: The city of Syracuse, N.Y., changed traffic signals at 299 intersections to LED traffic lights, as of This measure is saving the city over $225,000 annually. With the installation of LED traffic lights at 2,900 intersections, Chicago is saving $2.55 million in energy costs and $100,000 in materials, annually.

However LED traffic signals cannot melt snow One of the great advantages of LED traffic signals is that they do not waste energy by producing heat.

This advantage, however, could act adversely in some snowy scenarios as the LED signals are unable to melt away accumulated snow.

They cannot navigate safely when LED traffic lights are obscured by snow. Numerous accidents have been reported.

3 However LED traffic signals cannot melt snow One of the great advantages of LED traffic signals is that they do not waste energy by producing heat. The surface temperature of LED traffic signals mark between 10 to 20 degrees Celsius (50 to 68 Fahrenheit), while incandescent lamps hover near 45 degrees Celsius (113 degrees Fahrenheit). This advantage, however, could act adversely in some snowy scenarios as the LED signals are unable to melt away accumulated snow. Oswego, Illinois Heavy snow storms have taken a toll on the new LED signals Snow-covered traffic signals pose great safety threat to motorist and pedestrian. They cannot navigate safely when LED traffic lights are obscured by snow. Numerous accidents have been reported. Most cities resolved to manually clean off the snow, posing safety hazards to work crews as well. Also, snow removal job requires additional cost. Labor intensive, time consuming and waste of budget. Call for New Technology Numerous attempts have been made worldwide to solve the shortcoming of LED traffic lights. They include changing the shapes of the lenses, attaching additional covers, and applying special surface coatings. But none of them has provided definitive solution so far. Cleveland city, Ohio

5 Melt Smart, Your New Solution Snow Melting LED Traffic Signals by ZITEK To resolve the issues with accumulated snow, and provide ALL WEATHER energy-saving alternative to incandescent bulbs, ZITEK has developed Melt Smart, the snow melting LED traffic signals. Regular LED signal Melt Smart LED traffic signals maintain the same basic structure and function of the regular LED traffic signals. Not affecting the efficient circuit of the traffic signal, thus keeping all the benefits of LED signals, newly added Melt Smar technology effectively melts snow from the lenses with high-tech configuration. Melt Smart LED signal Key Features of the Melt Smart LED Traffic Signals Smart Sensors Multiple photoelectric and thermo sensors are embedded in the LED module of the traffic signal. With minimal electricity (0.1W), the sensors detect the snow accreted to the surface of the lamp and sets the heating element in motion. To avoid any false operation of the heater, photoelectric sensors and thermo sensors analyze the condition of the surroundings and controls the operation of the heater. Patented Heating Element Nichrome heating wire is securely embedded in the polycarbonate lenses of the lamps. Receiving the signals from the smart sensors, the heating element increases the surface temperature of the lamp until the accreted snow melts away. With patented technology, the element does not cause any deformation of the lens while emitting high-temperature heat and guarantees the same level of brightness.

7 Melt Smart, the Smart Choice Weather-Proof, More Effective Even during heavy snow, Melt Smart LED traffic signals are clearly visible. Snow does not accrete to the surface of the lamps because the heating element prompted by the smart sensors starts to melt it immediately (within 3 seconds). Melt Smart LED Snow starts to accumulate Regular LED Safe Melt Smart LED traffic signals immediately melts snow away providing drivers and pedestrian with clear visibility of the signals. Traffic accidents and possible loss of life could be avoided. After 25 minutes in the snow Efficient and Cost Saving After 45 minutes in the snow Smart, Error-proof configuration With the dual action of photo and thermo sensors, the Melt Smart operates the heater smartly. Certain preset conditions of snow coverage (photo sensors) and ambient temperature (thermo sensor) have to be met to turn on the heater and control its temperature. This guarantees economic usage of electricity because Melt Smart would work only when it is needed. By avoiding possible traffic disturbance and accidents caused by invisible traffic signals in the snow, huge cost is saved. With Melt Smart LED traffic signals, there is less need to send out crews for emergency snow removal, allowing for potential liability savings. Also, this allows maintenance staff to focus on other projects and lowers the cost to state and local government. Versatile Technology Melt Smar technology can be utilized in various fields including LED signals for automobile traffic, railroad traffic and airport control facilities wherever inclement weather disturbs efficiency of LED signals. ZITEK provides custom manufacturing solutions to clients throughout the world. We can manufacture various types and models of Melt Smart LED signals meeting any specification and regulations.
