The new traffic signal bulbs use Light Emitting Diodes (LED), rather than incandescent halogen bulbs. The LEDs are small, individual electronic lights created using applied voltage to a semiconductor chip and reflector inside a small colored lens or outer casing.
In contrast, the incandescent traffic bulb depends on a colored filter to produce the appropriate color. While the cost of the filter is cheap to produce, it is a very inefficient way to light the traffic signal. The red filter on a traditional incandescent signal bulb, for example, blocks 80 percent of the glow and wastes electricity.
The energy saving for the LED signal is significant. The LED traffic signal bulb uses approximately fifteen watts of power, compared to the average of one hundred watts of power used by the traditional incandescent halogen bulb.
Each traffic signal operates twenty four-hours per day, every day of the year. The cost to power a single one hundred -watt incandescent red bulb each day is about fifteen cents.
Many cities around the world are adopting LED displays in their intelligent transportation system. These versatile displays are commonly used as roadway & highway messaging, overhead traffic signs, tollbooth queuing guidance etc. They can be used in almost any display function along a roadway.
The Global LED traffic sign display market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
NSE traffic LED displays are being used in intelligent transportation systems in a number of locations across the world.
These multipurpose displays are often used for roadway and highway messages, overhead traffic signs, tollbooth queuing information, and many more. Almost every sort of roadside can benefit from traffic LED displays.
Traffic LED display programs can be updated remotely. There is no need to deploy workers to modify the LED display on-site, which saves money on running costs.
With increased visibility and strong brightness traffic LED displays both day and night are more effective than any other form of sign. NSE high-quality traffic LED displays can meet all of the traffic signage requirements.
