Smart Lighting System with Brightness and Color Temperature Tunable

Indoor smart lighting gradually comes into our home with the development of internet of things. Based on Jen Net-IP protocol, a smart lighting system with brightness and color temperature tunable is present. Each node in this system processes an IPv6 address, which enables every node be accessed and controlled remotely. Warm white cool white LED combination method to adjust color temperature is adopted in this system. Chip-on-board package structure to integrate different color temperature LEDs is also adopted. Every node in this system composes a JN5168 IEEE802.15.4 wireless microcontroller. A method to adjust brightness and color temperature respectively is proposed. Experimental results show that remote control unit, gateway and bulb can form a stable system which could satisfy the requirement for the indoor lighting.

I. Introduction

Solid-State Lighting (SSL) is one of the best choices for indoor lighting because of its various advantages such as low power consumption and long lifetime, etc. The requirement for higher quality of life brings higher demand for indoor lighting, including more intelligent and more convenient to operate and providing more comfortable light. The development of the Internet of things and Solid-State Lighting has promoted smart lighting coming into our lives.
