On the morning of September 7, at the China International Optical Expo (CIOE) sub-forum in 2016, Huang Feng, director of Philips Interconnected Lighting, brought the latest speech, clearly analyzing the intelligent lighting of the Internet of Things in the field of smart homes, smart buildings and smart street lamps. How it developed and landed.
Huang Feng said that the growth of IoT devices will surpass Internet devices in an all-round way. Lighting is an important facility of the Internet of Things. The lighting industry is undergoing subversive changes: 1. From 2014 to 2015, LED lighting shipments have far exceeded Traditional lighting shipments; 2, LED is a semiconductor device, can be combined with electronic devices for good control, LED lighting control can achieve interconnection, interconnected lighting is the most typical Internet of Things applications.
Interconnected lighting 5 related technologies
Huang Feng gave the interconnection lighting technology road:
1, LED technology, including light quality, drive power reliability, lighting and heat dissipation issues, switching, dimming and adjusting color temperature;
2, sensor technology, sensors closely related to home life, including human-machine sensors, illuminance sensors, etc.;
3. Communication technology, instant interconnection technology. The first layer in the home, or in the building, how to make local connections to the lamps in the house or in the building; the second level will link the received signals with the remote end, using the current communication technology;
4. IT technology, after receiving these data, how to carry out background processing? Such as cloud computing, big data analysis, cross-border data analysis and sharing.
5. Control technology. The first light is the switch control, followed by the mobile APP control, and more technology is added.
Smart home lighting competition is fierce, interconnection is the key, ZigBee is the first choice
Huang Feng believes that smart home interconnect lighting will undergo three stages of development, from lighting control to automatic lighting control, and finally to the intelligent lighting stage. It is now in the stage of automatic control from lighting control to lighting.
That is, mobile phone control, switch panel control, voice control and gesture control are converted to automatic time control, sensing automatic control, and other systems (such as curtains, air conditioning control) linkage control. The final stage of the smart lighting phase, expected to be realized in 2020, is an on-demand lighting, healthy lighting, and people-oriented lighting.
At this stage, the choice of smart home interconnection protocol, the preferred is ZigBee or Thread. In early May of this year, the ZigBee Alliance teamed up with the ZigBee Alliance China team to officially launch ZigBee 3.0 at the Asian Consumer Electronics Show in Shanghai. The main task of ZigBee 3.0 is to unify ZigBee Home AutomaTIon (ZigBee HA), ZigBee Light Link (ZigBee) LL), ZigBee Building AutomaTIon (ZigBee BA), ZigBee Retail Services (ZigBee RS), ZigBee Health Care (ZigBee HC), ZigBee TelecommunicaTIon services (ZigBee TS) and other application layer protocols, to solve the interconnection between different application layer protocols Problems such as ORVIBO's intelligent switch using ZigBee HA3.0 can be interconnected with Philips Hue smart bulbs. Users can control any ZigBee3.0-based smart device from ZigBee 3.0 by purchasing any ZigBee 3.0 gateway.
