- Operating System: Smart home systems network devices for the home and turn a smartphone or tablet into a universal remote, giving users control over their smart home devices and other systems. They can be integrated with other smart devices and systems to remotely control locks, lights, thermostats, cameras, and sensors, either with a tap or a voice command.
- Smart Device Apps: To use a smart operating system, users need to download the corresponding app on their smart device. This makes it possible to control lighting on a phone or tablet from any location. Using an app, lights can be set to switch on gradually in the morning to simulate sunrise or dim gradually at night when the user goes to bed. Bulbs can also be grouped into rooms on the app so that the user can switch the lights on or off in entire rooms or even floors at once, either with a tap or a voice command.
- Smart/Li-Fi Bulbs: There are many options for LED smart bulbs. There can be turned on and off, dimmed, or even change color via voice control or smartphone apps and integrate with smart home devices and home operating systems. Some bulbs use light fidelity (Li-Fi) technology, which creates fast wireless communications.
- Smart Wall Plugins: Some smart home lighting systems don’t use smart bulbs; they use smart wall Wi-Fi outlets, plugs, power strips, and plugins. With this technology, users can turn devices on and off remotely from anywhere with an Internet connection, set automation rules for intelligent usage habits, and monitor power consumption in real-time.
- Smart Sensors: Almost all smart lighting systems use sensors, consisting of a detector (heat, light, motion, sound), an electronic control unit, and a controllable switch/relay. The detector can tell when there are occupants in a house or room. It also has a timer that signals the electronic control unit after a set period of inactivity. The control unit uses this signal to activate the switch/relay to turn equipment on or off.
Smart Home Lighting Systems: Conserves Energy
In 2016, total global energy came from 80% of fossil fuels (coal, natural gas, and petroleum). The main fossil fuel being used is natural gas (32%), coal (30%), and petroleum (1%). Processing all three forms have numerous damaging environmental impacts, such as air and water pollution, soil contamination, etc. 6% of greenhouse emissions in the world derive from energy used for lighting. Globally, 19% of electricity use is for commercial and residential lighting. With new smart lighting, residential energy use will decline by more than 50% in the range of 1,000 kW hours per household per year from 2012 to 2040. A typical lamp using a traditional light bulb consumes 60 watts of power, and a compact fluorescent lamp emits the same amount of light while using only 13 watts. [1,2] However, smart lighting using light-emitting diode (LED) bulbs consumes only 10 watts to give off the same amount of light. Besides conserving energy, smart lighting systems enabled with the Internet of things (IoT) technology can save people money by allowing them to remotely control their lighting, which lowers their energy use and saves them money. According to a report, new lighting technologies can reduce lighting energy by up to 75%. Also, by using LED lights, which are more energy-efficient and last up to 10 years, smart home lighting systems lower energy bills over time.  Smart Lighting Systems Technology To design a smart lighting system, several products need to be purchased and installed. The first step is to install smart bulbs or wall plugins. The next step is to install smart sensors and integrate them with the technology used for the bulbs or plugins with an operating system. The related app needs to be downloaded to a smart device to operate the system. Below are more details about the technology that’s needed for setting up a new smart lighting system:
