The trend of the transformation of cities in smart cities is picking up pace. The power consumption, renewable energy, and emerging technologies are contributing to the introduction of the idea of intelligent and automated cities. The smart lighting application is expected to play a vital role in achieving sustainability and saving energy. The smart cities are expected to offer lucrative opportunities for lighting solutions, since the smart city revolution is spreading rapidly. The cities which have adopted the intelligent lighting technology and are reaping its benefits have been willingly recommending other cities on how to implement a smart city strategy that would be beneficial in the coming years in terms of increasing energy efficiency and reducing energy cost, maintenance cost, and carbon emissions.

Urbanization is taking place at a faster rate in APAC; both developed and developing countries in the region are looking to adopt smart city technologies. The Middle Eastern countries, as well as India and China, are particularly adopting the concept of smart lighting for developing smart cities. Lighting accounts for a major portion of the total energy consumption across lighting applications. Lighting is a critical concern for public authorities in developing countries because of its strategic importance for economic and social stability. Inefficient lighting solutions waste significant financial resources each year, and poor lighting creates unsafe conditions. To overcome these issues, various countries are planning or implementing smart lighting projects. For instance, Jakarta, Indonesia, has plans of replacing over 90,000 lights with LED lighting systems, thereby targeting to achieve about 70% energy savings. Moreover, in March 2019, Shanghai Municipality partnered with Signify (Philips Lighting) (Netherlands) to illuminate the Bund in Shanghai with tunable white LEDs, which would help Chinese cities to develop more eco-friendly business and tourist landmarks by using connected LED lighting to reduce energy use and minimize operating costs.

Increasing use of LED lights and luminaries in outdoor lighting applications

One of the key reasons for installing LEDs over conventional lights is energy and cost savings. LEDs are replacing conventional light sources such as fluorescent, high-intensity discharge (HID), incandescent, and high-pressure sodium lamps in outdoor lighting applications. Outdoor lighting applications, primarily include highways, roadways, public places, and stadiums. LED lights and luminaries are more energy more efficient than the conventional lighting sources. Therefore, increasing use of LED lights would lead to decreased energy consumption, thereby reducing energy requirements. According to the US Department of Energy (DOE), LED lighting would represent 86% of all lighting sales by 2035 due to the benefits offered by LED lights over its conventional counterparts.

Although LED light sources are energy efficient, over 30% of lighting energy consumption would be wasted if the appropriate controls are not used. Best lighting control systems combined with LEDs would increase the life span of an LED light source, which would minimize the maintenance costs, thereby further reducing the duration of payback periods. Hence, LED lighting solutions equipped with a dynamic lighting control solution would reduce the amount of lighting energy consumed. All these advantages have encouraged construction enterprises associated with building highways and stadiums to deploy LED lighting systems.

Government initiatives and policies for energy savings

Increasing use of energy sources is resulting in the rising level of energy dissipation and carbon emissions, which creates the need for sustainable and efficient use of energy. Power production accounts for nearly a quarter of the greenhouse gases. Rising concerns over global warming and ozone depletion have accelerated the efforts by the governments of developed and developing nations to control their carbon footprint. Governments from all over the world are imposing strict regulations to limit the carbon release. According to the Electric Power Research Institute (EPRI), the integration of renewable energy sources in smart grids could reduce the greenhouse gas (GHG) emissions by 19–37 million metric tons (MMT) Co2e/year by 2030. Therefore, rising concerns to reduce GHG emissions have driven the transformation of traditional utility grids into smart grids, which make use of renewable sources of energy generation.

Several laws and regulations across the world aimed at reducing energy consumption and spreading awareness regarding energy conservation has been enacted by regional governments across the world.

The lighting control system is an intelligent network based on a lighting control solution that incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. A communication protocol is a set of standard rules—syntax, semantics, and synchronization—for communicating over a computer network or a lighting control systems or both. The protocol defines the methods for data representation, signalling, authentication, and error detection to ensure control or enables the connection, communication, and data transfer between computing or control endpoints. The introduction of communication protocol has led to the growth of the best lighting control systems space. Currently, wireless communication technologies have started gaining momentum in the lighting control systems market as they reduce the usage of wires, thereby offering convenience to the end-users.

The growth of the lighting control systems market is largely governed by the availability of specialized solutions to address the varied requirements of different end-users. Each of the aforementioned industry segments has varied bandwidth requirements depending on the amount of data to be transmitted, the coverage area, and the data load. Thus, it is essential to explore different technologies available and ensure the effective utilization of relevant technology for specific applications in a cost-effective manner.

Wired

The wired communication protocol of the lighting control systems space includes Digital Addressable Lighting Interface (DALI), Powerline Communication (PLC), Power over Ethernet (PoE), various wired hybrid protocols, and others, which include various company-specific proprietary protocols.

1. Digital Addressable Lighting Interface (DALI) - DALI provides centralized control daylighting and occupant control capabilities, enables application flexibility, and provides significant energy savings.DALI can be used for scene selection and for getting feedback regarding faulty light sources, which makes this protocol useful in cases, where remote supervising is required. A DALI system could be as small as a single luminaire but is scalable to multiple systems across a building or more, where DALI systems can be connected using lighting hubs/routers. DALI facilitates interchangeability between products of different vendors and enables consistent performance across manufacturers. DALI uses a distributed system, in which each controller operates as a master and controls communication on the control line; and the ballasts and drivers are slaves, which react at the request of the DALI control device.
2. Powerline Communication (PLC) - Powerline Communication (PLC) is a wired technology that uses electric power for data transmission. In PLC, the signal transmitted via a coupler is incorporated into a transmitting device and then into a power cable. The receiving device or the PLC modem then converts and receives the data signal, thereby establishing the communication. PLC uses a conductor to carry the data, which is used simultaneously for the transmission of AC electric power. A PLC adapter extracts the data signal on the division of overlapping signals. PLC technology transforms wall power outlets into information outlets, thus enabling the convenient building of a universal in-home networking system.
3. Power over Ethernet (PoE) - Power over Ethernet is a technology, which enables the power required for operating devices such as lighting, VoIP phones, wireless access points, and IP cameras to be supplied through data cables instead of power cables. The use of POE with lighting systems offers several benefits such as it removes the need for connecting lighting devices with separate cables, and it provides flexibility in the design of the best lighting control systems where it makes the systems portable. With the rise in the adoption of LED luminaries and lights due to their capabilities of offering higher efficiencies than traditional lighting and also, they require less power, which thereby, drive the demand for PoE lighting control systems.
4. Hybrid -Wired hybrid protocols refer to those protocols that combine the advantages of proactive and reactive routing of data and instructions. The routing is initialized using proactively determined routes and is then satisfied with the help of reactive flooding, based on the demand from the activated nodes.
5. KNX and LonWorks - Konnex (KNX) is a worldwide communication standard for home and building controls. The use of KNX lighting control applications helps to control energy usage in residential and commercial buildings. The use of KNX for lighting control helps to reduce energy usage and also helps to control the carbon footprint.LonWorks protocol has its major application for devices used in building automation, HVAC and lighting. This protocol can also be used for outdoor lighting applications. LonWorks allows many manufacturers to produce high-end hardware as well as software products.

Wireless

Wireless communication protocols are needed for communication between the evolving technologies. This section includes wireless protocols such as ZigBee, Bluetooth, EnOcean, Wi-Fi, and 6LoWPAN. The lighting control systems market is flourishing, which has attracted other wireless technology vendors.

1. ZigBee - ZigBee is the language of connected lighting in homes and businesses. It provides consumers with an easy-to-use control over all their LED fixtures, light bulbs, and remotes and switches. Products based on ZigBee wireless protocols allow consumers to change lighting remotely to reflect ambience, task or season while managing the energy use and making their homes greener.
2. Bluetooth - Bluetooth is the third-generation networking technology that eliminates disturbing cables that limit the mobility of a user. It aims to make daily lives more comfortable, safer, and more energy-efficient by focusing on infrastructure-based applications such as automation, control, security, and energy management. The Bluetooth network protocol strikes a balance between range, power consumption, reliability, bandwidth, and cost. It ensures interoperability and increases consumer confidence, creates value for both the end-user and the service aggregator.
3. EnOcean - EnOcean wireless technology uses a combination of energy harvesting and very low power wireless communications, which enables virtually indefinite communications to be maintained without the need for recharging. EnOcean modules combine micro energy converters with ultra-low-power electronics and facilitate wireless communication between wireless sensors, switches, controllers, and gateways. This wireless technology eliminates the need to install wires between the switch and controlled devices. EnOcean technology is a simple, fast, and value-added alternative to cabling, breaking, and other time-consuming and expensive renovation activities. It allows a quick installation of lighting control and management systems and helps promote wireless solutions in building services and other sectors.
4. Wi-Fi - Wi-Fi enables devices to connect directly to each other or to broader networks to deliver information, thus proving to be a key technology that drives the lighting control and management systems. It operates in the frequency of 2.4 GHz and has five channels (there are slight modifications in operating frequencies and standards in various countries). Wi-Fi can be accessed through various devices such as video-game consoles, smart appliances, and a few types of digital cameras, personal computers, tablet computers, and digital audio players. These devices can connect to the Internet through a wireless access point.
5. 6LoWPAN - 6LoWPAN is an acronym for all IPv6 protocols that cover Low Power Wireless Personal Area Networks. 6LoWPAN protocols have pre-defined mechanisms for encapsulation and header compression, which allow for sending and receiving of IPv6 packets over IEEE 802.15.4-based networks.
6. Hybrid - Wireless hybrid protocols are similar to wired hybrid protocols in the process that combines the advantages of proactive and reactive routing of data and instructions. The routing is initialized using proactively determined routes and is then satisfied with the help of reactive flooding according to the demand from the activated nodes.
