LEDs are the most advanced standard in traffic signals, mainly due to the Energy Policy Act of 2005 which set minimum standards for energy efficiency in traffic signal and pedestrian modules. The “Vehicle Traffic Control Signal Heads: Light Emitting Diode (LED) Circular Signal Supplement” specification effectively addresses the physical, mechanical, photometric, & electrical requirements for LEDs, encompassing environmental requirements for protecting LEDs from dust and moisture intrusion, including blowing rain. One of the unintended consequences of the transition to LED module traffic signals lenses/indications is the fact that LEDs do not generate heat to the traffic signal lens or face of the traffic signal display. Therefore, LEDs do not provide a “melting” element to traffic signals in the northern climates that experience snow and ice conditions.
Although LEDs typically have a much higher purchase price, they are far more energy-efficient and longer lasting than their conventional counterparts which leads to lower total costs when factoring in electricity savings and reduced maintenance and disposal costs. When compared to available alternatives, LED traffic signal modules are often the best cost value choice because they offer improved visibility; low power consumption, infrequent maintenance and replacement, and, unlike HPS and other mercury-containing street lights, contain no hazardous components that require special care.
Traffic management professionals around the world are leaving maintenance intensive and energy hungry incandescent lamps by the curb and heading for the robust, high-reliability advantages that LED signal head offer. With up to 90 percent energy savings and a long-rated life, LED signals outshine incandescent traffic signals and offer significant advantages in dealing with sun phantom, light uniformity and color washout issues. Designed for direct retrofit or OEM applications, LED traffic signals are available in designs that can meet current ITE, Caltrans and other key geographic standards.
Sometimes in freezing winter and sometimes in sultry summer, sometimes in sunny days and sometimes in rainy days, the working environment for traffic lights is relatively harsh, thus traffic lights has higher requirement for stability. General lights with incandescent bulbs have an average life expectancy of 1,000 hours, while halogen light bulb have 2,000 hours, so the resulting maintenance costs are high. LED traffic lights lifespan is about 80,000 hours and do not suffer from damages caused by filament shocks or glass broken problems.
From every perspective LED traffic signals are the best option – be it for a busy traffic junction or lesser one. They will definitely create a new revolution in the traffic lighting industry in the near future.
Have you ever though how LED signage work, but could not comprehend all the technicalities that majority of the LED signage firms use to explain them? Do need to be worried! It is not that tough as you used to believe.
LED Module: Well, Modules are composed of LED, PCB, IC, resistors, capacitors, connectors, covers and other components by special techniques Modules have matrix of 8×8, 8×16, 16×16, 16×32 and so on, and the corresponding pixels are 64/128/256/512. Pixel pitch is the distance between two adjacent pixels from the center point, such as PH4.75, PH6, PH10, PH16, PH20, and so on. You can see modules are extensively used in 
LED light is the modern technology, which is very beneficial in the traffic signals because of it incandescent light and uniformity in color. 
Some of the features and benefits of LED traffic modules
Traffic Modules around the world use more than 3 billion kilowatt-hours of electrical energy every year. The energy consumption can be significantly reduced by the use of LED in traffic signal modules that promise to be the best replacement for the traditional traffic modules based on incandescent lamps. Many developed nations have already started to replace the traditional traffic signal modules with the LED signal modules and are enjoying the benefits of LEDs.
There is another great reason for using LED in traffic signal modules instead of incandescent lamps. When the weather conditions are not the best, the visibility can often become poor due to the dust. 
Today, LED lights have become the prime sources to light together after they attach to any panel comprised of a particular shape. You will find many shapes categorized under LED panels, whose functions vary largely. In this article, you will get details about applications of LED lights in the form of LED traffic modules and LED powered traffic signal heads.
• The product has proved to be an innovative optical technology to allow drastic savings on both maintenance and energy costs.
LED lights are the light emitting diodes and they are now being used in different things as the benefits of these LED lights are very high and hence more and more people are using these LED lights for their uses. One such use of these LED lights is that these LED lights are used in the 
These traffic signals are having modules of very high quality in order to provide the better quality to the traffic signals. And to make this possible, instead of using cheap lights, LED lights are now being used in these 
Traffic Signals are something which are really important for the proper functioning of the traffic as this is because of the traffic lights only that the traffic is avoided and the traffic runs smoothly. The traffic signal consists of three basic colors and these colors are red, green and yellow. The meanings of the colors are explained to the people right from their school time only and there are really strict rules which are made by the government to follow the traffic signals. This is because when people follow the traffic signals correctly the traffic jam is avoided. Basically these traffic signals consist of the 
You must have seen that in a traffic signal the light turns from red to green, green to yellow and yellow to red and this keeps on going continuously. Whenever when color is started the other one is switched off automatically and all these activities which are being done in a traffic signal are being done on a 
The three lights ‘RED’, ‘GREEN’ and ‘YELLOW’ work as traffic lights. These colours are bright and are visible from far and we see them at every traffic signal. ‘RED’ stands for ‘STOP’, ‘YELLOW’ for ‘GETTING READY’ and ‘GREEN’ for ‘GO’. The lights are either arranged vertically at the post for the vehicles to notice from far and usually the when the lights turn ‘red’, the cars are supposed to stop.
The Look and Utility Of The LED Module Traffic Head
For such a long time the biggest terror of primary LED adopters was the technology would rapidly become expired. With the introduction and enhancement of the LED module this’s no longer a problem. The module podium has unlocked new promises for the lengthy utilization of LED in a diversity of surroundings encompassing hospitality, traffic, retail, advertising, aviation, decorative illumination and even digital gadgets. This approach offers all the advantages of employing LED light alongside the aptitude to influence ongoing enhancements & technological revolutions.
Another advantage of 
While crossing the road, we are always taught to look both sides and nowadays we are asked to watch the Traffic signal. The Traffic Signal is a very important element of any road be it a highway or a busy lane. The Traffic Signal has three lights namely, ‘RED’ for ‘STOP’, ‘YELLOW’ for ‘WAIT’ or ‘BE READY’ and GREEN for ‘GO’. The lights are arranged vertically in the order or ‘RED’, ‘YELLOW’ and ‘GREEN’. The three lights appear for the vehicles and when it is ‘RED’, people are supposed to cross the roads.
The signals are installed within one black vertical box containing colour LED lights usually Circular in shapes and this box is attached to a high pole so that the Drivers can notice the signals and follow them from a far distance. The usual count for the lights remains for 1 minute or 2 covering the three lights. On an average of every 5 minute, the light changes from ‘Green’ to ‘Red’. Nowadays, signals show human figures instead of simple lights. When the Human walking figure is ‘Red’, the vehicles move while when the same figure shows ‘Green’, the people cross the street or the road. The boxes can thus be vertical rectangle, or a horizontal rectangle or a square even. Henc, the
