With the development demand of the smart city, it is important to save energy and decrease the carbon dioxide emissions. The electrical energy consumption of street and outdoor lighting consti- tutes an important part of total energy consump- tion (Zotos et al. 2012). There are two important ways to save energy and decrease the carbon diox- ide emissions on the street and outdoor lighting: one way is to replace all the traditional lightings to the LED lightings, according to the statistics from TALQ consortium, if all the outdoor lightings in US are replaced to the LED lightings, then it could decrease the emissions of the CO2 as much as 90 million metric tons and save much energy, and the number of those outdoor lightings needed to replace in some districts are exemplified as follows: over 50 millions outdoor lightings in US, over 80 millions outdoor lightings in Europe and over 17 millions outdoor lightings in china (Jin & Nim 2014, TALQ Consortium 2015), so it is an impor- tant way and will be realized in the near future; the other way is to control the outdoor lighting systems intelligently, which will save energy and decrease the carbon dioxide emissions on outdoor lighting control systems through the adaptive and interop- erable controls (Mohsen et al. 2014, Siddiqui et al. 2012, Schaeper et al. 2013, SangCheol et al. 2013), so the outdoor lighting intelligent control system becomes an important part of the smart city, espe- cially to the LED outdoor lighting control system.
Lighting Control Panels
Published in Craig DiLouie, Lighting Controls Handbook, 2020
For the lighting control system to be able to communicate with the building automation system, a common language is needed. The most popular are BACnet and LonWorks. Devices designed according to these protocols can interact seamlessly with similarly designed devices. Or a gateway can be used, which is a device that acts as an interpreter between controls built to operate on different protocols.

For example, F. Tan et al. (2018) suggested a lighting control system, in which indoor lighting control was achieved with the use of occupancy and light sensor data to adapt artificial lighting in accordance with changing occupancy and daylight conditions. Anca D. Galasiu et al. (2007) conducted a field study in an open-plan office building equipped with suspended direct-indirect illuminates located centrally in cubicle workstations. They collected data from 86 workstations over a year to examine the energy savings by employing occupancy sensors and daylight sensors, as well as individual dimming control. Results indicate that the energy consumption was reduced by 67% to 69%, compared with the conventional fluorescent lighting system on neighboring floor.
