A lot of us have gone through the period of employing incandescent light lamps. Many probably don’t know that even though the incandescent bulbs release massive volume of lighting, they aren’t quite convenient source of energy since they required to be substituted quite often. Another lighting option you must have idea about is the fluorescent one. People favor this form of lighting source since they don’t require to be substituted quite often but they come with their cons as well as, for example steady dimming can be noticed with continuous usage. Furthermore, this form of lighting is also considered as a threat to the atmosphere since they feature heavy metals like mercury & harmful phosphates which can be risky to the wellbeing of plants and animals which eventually have an effect on our environment.
However most of the above mentioned problems can be ignored with the employment of lighting sources that employ LEDs. LEDs are small lamps and energy is discharged when electrons shake at a particular frequency, therefore LEDs don’t employ filament. A tiny LED lamp varies in terms of dimension from 3mm to 8mm, therefore it releases considerable sum of lighting but not enough that proves to be pretty useful. Therefore many LEDs are placed on a panel and collectively adequate light is emitted. The panel can be shaped according to need but there are some popular designs which have gotten a specific name such as LED Bars, LED Tubes, LED Flex and LED Modules.
Well, LED traffic light modules are generally round in shape and available in different sizes. They generally employ aluminum as a holder that seizes the panels. Aluminum is favored since it’s affordable, and it feature reflective surface this light can be easily reflected from the module. The panels in LED module can hold up to 100 LEDs; therefore they are quite useful when it comes to traffic led light. They are in fact used as traffic light core to a great extent.
Apart from round shape, LED modules can be also purchased in other diverse shapes. Sizes and shapes are variables aspects but color of light is another crucial aspect that a lot of people ponder on before purchasing. LED modules are also accessible in Green, Blue Yellow and RED which make the ideal for traffic lighting. Today you can easily come across traffic light manufacturer that use the LED module technology to their best effect.
It cannot be denied that LED (light emitting diode) lighting is very useful not only to people but also to social groups and big businesses. Stands for light emitting diode, LED itself is a semiconductor light supply & since 1992, it has been widely adapted for different kinds of equipment to cater many purposes that need illumination. Nowadays, LED lighting is extensively employed for diverse purposes, for example, in traffic signals, automotive lighting, outdoor lighting and in aviation as well. LED lamps are recognized to be dependable because of its narrow bandwidth, adjustable switching speed, and compact size among others.
There are several benefits of modern LED lights, credits to their smart design, flexibility and dependability. They have proven to be quite energy competent when it is about power consumption, especial in the traffic intersections. In your city now you can notice the wide use of 
Traffic light manufactured in various places at India by plenty of companies in different scale. Along with traffic light, companies are work for smoothening in many other parameters like optimum visibility, energy saving etc. In traffic light manufacturing, companies have major challenge to maintain variety because huge number of notations present in traffic monitoring system.
LED lights have instant on/off startup times so it can easily operate in solar energy module also. Red , Green , Yellow LED lamps unlike white lights beaming through a colored lens filter have sharp and clear colour.LED light core has different colors (blue, whitish red, green, amber or yellow) and size(100mm-300mm and more)these are common now a days. In streetlights and traffic light these core are encapsulate and form various shapes.
Traffic is one of the biggest problems being faced by the world. The population is increasing and along with the population the number of vehicles is also increasing rapidly. Many people are there who are having even more than two vehicles at their home. This has resulted to a problem of high traffic at a lot of places and hence it is really difficult to maintain the whole traffic and this task of maintaining the traffic and also looking after the free flow of traffic is done by the traffic signals. These traffic signals are actually really helpful in smooth functioning of the traffic. People follow these traffic signals to avoid any kind of problems while driving and hence these traffic signals are one of the most important things that can be found on the streets.
Now, you must be curious to know about the manufacturers who make these traffic lights. So there are a lot of different companies in the world who are manufacturing these traffic lights. Different countries have their different 
Every year, approximately 4 millions of total traffic lights consume about 3 billion KW of total electricity available. Thus, switching to LED light fixtures offered by reputed 
LED light fixtures are capable of producing light only in required colors, which include green, red and yellow, which make them ideal products for traffic lights. In this type of product, users do not require filtering of the light by using lenses.
Today, LED lighting systems poised to transform almost every form of lighting, as they give plenty of benefits as compared to fluorescent and incandescent light bulbs. Selection and acquisition of LED lights compulsorily require every buyer to collect information about latest terminologies and consider key factors while purchasing of lighting systems for commercial purposes. With the help of this article, experts have guided individuals working in traffic control and traffic light sector in selection of right 
Along with the overview on LED powered lighting systems, it is essential for you to stay aware of its mechanism before approaching any traffic light manufacturer. Whenever electricity passes from any traffic light system powered by LED, it emits energy as a beam of light. LEDs are semiconductors, which come with injected or doped chemicals to determine lights of specific colors.
Light emitting diode lamps or LED lamps use light emitting diodes as a major light source. Here, the light emitted by an LED is of relatively less than any other compact fluorescent and incandescent bulbs. Hence, most of the traffic light manufacturers nowadays put large numbers of LEDs all together to create suitable LED lamps.
Manufacturers of LED lighting systems perceive that most of the LED lights give competitive benefits as compared to several other types of lights. These include
The other advantage is that the devices require just small amount of power to work; therefore, you spend less on your electricity. The reason why they require just small amount of power is because their efficiency is very high. This is why LEDs are termed as the best alternative as far as 
People know traffic lights with different names, like spotlights and traffic signals. These play major role to control the road traffic. Initially, these lights comprise of only two lamps i.e. a green and a red color, which has still found its usage in many countries. However, in case of those traffic lights, there was no way to operate changing of lights automatically; instead, individuals have to change or operate it manually. In other words, traffic officers have to remain present to turn the lantern for making sure of facing right light for the traffic.
Yellow color is mainly found in between green and red, which indicates vehicle drivers to be ready for activation of green color and finally on displaying of green color, one has to move ahead or cross the road. Interestingly, green and red colored lights mostly last for relatively long hours than yellow one. In some special cases, you have to stay at stop light for about 5 minutes or even more whenever you found shinning of red light. This type of situation takes place whenever construction work takes place across the road.
