The idea is that when you walk into the room, your phone will sense your presence there, and your house will adjust the lighting accordingly. Google sees this as the first step towards IP enabled full home automation.
Lighting Science Group, a Florida-based lighting firm calls it “intelligent LED lighting,” and announced it during Google's keynote presentation at its I/O developer conference in San Francisco. The first product, a 60-watt equivalent bulb, is a combination of Lighting Science’s knowledge of light geometry and Google’s connected software know-how.
An Internet-connected LED bulb? Yes. With a little help from your home’s Wi-Fi network, you can dim or turn off lights remotely — or to program them to do so. Better still, the LED bulbs can leverage your smartphone’s GPS and proximity sensors, turning on lights when you walk into a room with the phone in your pocket. Google has always occupied the home area network space, but this is the first time it has addressed a specific appliance in the home.
