smart bulb
Smart Bulb stands for intelligent light bulb. It is an LED light equipped with a radio module that can be controlled in various functions via a smartphone. Smart Bulbs expand the possibilities of Smart Lighting by automatically and remotely adjusting brightness and color temperature.
To enable Smart Bulbs to cover a wide range of colors, they consist of three-color LEDs for red, green, blue( RGB). The RGB color model allows the color temperature to be changed between extremely warm tones with color temperatures of about 2,500 K, to extremely cold colors with 8,500 K. In addition to these basic functions, which include on/off, timed control and dimming, smart bulbs support streaming audio that they can distribute throughout the home and geofencing, which is supported by the GPS system in the smartphone. Geofencing can be used to control lighting and always turn the lights on or off in the room the user is currently in.
WiFi, Bluetooth and other short-range technologies are available as wireless systems. They are controlled via an app from a smartphone or tablet, and can also be controlled from a central smart home hub. Depending on the app, individual smart bulbs or even groups can be controlled.
