EnOcean-based wireless and passive intelligent bathroom lighting system

Abstract

The invention relates to an EnOcean-based wireless and passive intelligent bathroom lighting system. The system comprises a lighting controller, an EnOcean wireless and passive rocker switch, waterproof light emitting diodes (LEDs) and an illuminance sensor, wherein the lighting controller comprises a microcontroller, an EnOcean wireless transceiving module, an LED driver, LED driving universal serial bus (USB) interfaces, an LED driving pin, an illuminance sensor interface, a piezoresistor, an USB interface module, an universal asynchronous receiver / transmitter (UART) converted to USB module and a power supply module.

Description

technical field [0001] The invention relates to a bathroom lighting system, in particular to an intelligent bathroom lighting system. Background technique [0002] With the development of IoT technology and lighting technology, wireless technology WIFI, Zigbee, Bluetooth and other technologies are applied to indoor lighting technology, resulting in an indoor intelligent lighting system. It is promising to replace wired switches with wireless switches to avoid wiring, but this method has the problem that wireless switches need to be replaced regularly, which consumes energy and brings inconvenience to users. In the design of indoor intelligent lighting system, the design of bathroom lighting system has become a difficult point, because the bathroom has the characteristics of small space and high humidity. It is difficult for the existing intelligent lighting system to meet the requirements of high safety and long service life while realizing intelligent lighting. . In the p...

AI Technical Summary

Problems solved by technology

However, the wireless switch needs to replace the battery regularly, which is inconvenient and increases energy consumption, and cannot guarantee the safety and service life of the device in the high humidity environment of the bathroom, so it cannot be used in the bathroom

[0003] Chinese patent document CN201410007651.3 discloses a building lighting control network based on EnOcean, which has the advantage of being able to achieve wide coverage of wireless networks, but first the networking method used in this patent is through terminals and repeaters , sub-network controller, sub-network control unit and remote control unit, the system is too complex and not suitable for intelligent lighting system design in small spaces such as bathrooms. Secondly, the patented technical solution does not mention the use of lighting drivers. For bathrooms For this occasion, there are special requirements for the lighting driver, and the effect of ordinary lighting drivers is difficult to guarantee the lighting effect

And this patent can only adjust the brightness, and the bathroom intelligent lighting system often needs lighting with different color temperature and brightness under different usage conditions
