Smart street lighting initiatives are becoming increasingly popular as hardware costs and ROI fall. LEDs are directional light sources that pay for themselves in eight to ten years. IoT-enabled lamps also offer a 30% cost savings over the bulb’s lifetime. While the initial costs of connected lighting may be a little higher than those of LEDs, the long-term savings are significant. Additionally, connected street lighting initiatives improve road safety and reduce maintenance costs.
LEDs are directional light sources
There are many benefits to LEDs for smart street lighting. LEDs can be dimmed using pulse-width modulation, unlike incandescent, fluorescent, and high-intensity discharge (HID) lamps. and LEDs emit only directional light and are not capable of generating a spherical glow. LEDs are generally used in downward or hanging streetlights. Because of these advantages, they are considered well-suited for outdoor lighting. LEDs also have a wide range of operating temperatures, making them a great choice for flood zones.
The earliest LEDs were developed by Italian physicist Alberto Barbieri, who was on leave from RCA Laboratories. In 1972, he demonstrated a blue LED, using zinc-doped gallium nitride. The trio also collaborated with Jacques Pankove and Ed Miller to demonstrate the first blue electroluminescence. This led to the issuance of U.S. Patent US3819974 A for this development.
Intelligent street lighting systems are self-adaptive distributed networks
Intelligent street lighting systems provide advanced dimming and scheduling capabilities. They utilize sensors and control mechanisms to create a self-adaptive distributed network that can respond to varying road conditions. The wireless radio modules in these systems typically operate as a mesh network, ensuring high levels of reliability. The network is capable of supporting a variety of smart devices. Smart lighting systems can be integrated into citywide infrastructures for improved connectivity and livability.
The benefits of an adaptive lighting system can vary from place to place and are highly dependent on the number of lights, the environment, and behavior. One study in the UK showed that smart streetlights could save PS3.2 million annually in energy costs. It is anticipated that the energy savings will exceed 60% in the city after the new system is installed. The overall energy savings are projected to total PS54 million over the next 20 years.
They can enhance road safety
The latest developments in smart street lighting have the potential to improve road safety and reduce carbon emissions. These technologies include embedded microprocessors, wireless transmitters and sensors. These technologies can also perform functions such as detecting air pollution and haze, which could lead to fewer traffic accidents and criminal activity. Furthermore, these technologies can help cities reduce maintenance costs. By integrating these technologies, cities can create a safe environment for their citizens and improve their public safety at the same time.
Some studies have shown that bright, broad-spectrum road lighting can reduce the number of car-versus-pedestrian collisions. However, it has not been proven yet whether or not whitening street lighting can prevent road traffic collisions. Other research, such as a pilot study conducted in London, suggests that such street lighting has a significant impact on road safety. However, these findings require large datasets to assess the actual benefits of smart street lighting.
They can reduce costs in maintenance
If your city’s streetlights are old-fashioned, it’s time to upgrade. But LED lighting alone will not bring you any real intelligence. A smart street lighting system can predict lamp failures and schedule maintenance tasks ahead of time, reducing maintenance expenses. Additionally, it can support solar power capabilities, digital signage, and environmental condition monitoring. Additionally, these lights can transmit data to the city’s cloud-based light sensor network to support a wide range of city services and initiatives.
While smart street lighting can reduce maintenance costs, the implementation of these solutions will require training and specific maintenance procedures. Furthermore, government officials should develop tools to measure the solution’s performance. Moreover, because these features are typically developed for other applications, they are difficult to maintain on a large scale. To address these challenges, the government should invest in a comprehensive monitoring system and the tools necessary to optimize and manage them. Smart street lighting systems also offer benefits to cities that want to implement the newest technologies.
They can contain built-in speakers
For public safety and security, smart street lights can contain built-in speakers, cameras, and sensors. These devices send real-time data to authorities or emergency personnel, triggering a swift response. Smart street lighting systems can also be combined with CCTV, speakers, and charging stations for electric vehicles. They may also contain audio features like MP3 players. But what are the benefits of smart street lighting systems? Here are some of them:
One of the benefits of smart street lighting is that it can play music and be controlled by sensors, which can be turned on and off. They also have the benefit of being able to communicate with each other in various languages, enabling two-way communication. In addition to providing increased safety, smart street lights can enhance the nightlife experience and improve demand management. The city of San Diego has partnered with Global Green Lighting to install smart lights in the urban core.
