“…However, most of these works are based on powerful PCs and servers. For example, the work of Wang et al [31] presents a system for a digitally-controlled ballast for ultraviolet lamps based on a ZigBee DALI bridge module that connects to a PC. Such systems, although powerful, do not have the flexibility and variability of applications provided by embedded microcontroller-based control architectures like the system proposed in this research.…”

Light emitting diodes (LEDs) as an efficient low-consumption lighting technology are being used increasingly in many applications. The move to LED lighting is also changing the way the lighting control systems are designed. Currently, most electronic ballasts and other digital lighting devices implement the Digital Addressable Lighting Interface (DALI) standard. This paper presents a low-cost, low-power effective DALI LED driver controller, based on open-source Raspberry Pi3 microcontroller prototyping platform. The control software is developed as a Linux kernel module under UBUNTU 18.04.2 LTS patched with PREEMPT_RT (Preemptive Real-time) for real-time processing. This dynamically loaded kernel module performs all the processing, communication and control operations of the Raspberry Pi3-based DALI controller with the DALI LED driver and LED luminaire. Software applications written in C and Python were developed for performance testing purposes. The experimental results showed that the proposed system could efficiently and effectively manage DALI LED drivers and perform lighting operations (e.g. dimming). The system can be used for a variety of purposes from personal lighting control needs and experimental research in control of electronic ballasts and other control gears, devices and sensors, to advanced requirements in professional buildings, including energy management, lighting maintenance and usage.

“…For instance, to reduce the energy consumption of the public lighting and at the same time increase the power efficiency and lighting quality level, in [19] is presented an advanced control system. Whereas for the communication of the lighting modules, in [20] is explained the development of an electronic system using ZigBee module with DALI protocol to send and receive commands. As can be seen, there are many works that proposes equipment or even algorithms for street lighting applications.…”

Smart lighting applications are designed to provide management and control of the whole interconnected system, ensuring reliability, cost saving and high efficiency. In this work is proposed a simple intelligent module to be connected in the street lighting system in order to simultaneously control and measure the lamp's parameters. All the data transmission procedure was developed based on the mesh network topology. By taking advantage of the communication structure used for the smart lighting system and coupling sensors to the module, it's possible to gather data regarding the power grid as well. Moreover, for experiments purposes, it was also developed a specific driver capable to communicate by DALI protocol in order to receive and send information from the smart module to the lamp. The results have proven the efficiency, flexibility and interoperability of the proposed smart device.

“…The control system captures an image, performs on board image analysis, transfers the image transformed data for further processing and calculates the appropriate light output levels, which are transmitted to the luminaires through the DALI [17,46,47] controller ( Figure 1). Significant energy savings can be achieved in lighting without sacrificing productivity [48,49]. Microcontrollers can contribute towards this direction since they are characterized by low cost and sharp application design and implementation.…”

Embedded Microcontroller with a CCD Camera as a Digital Lighting Control System

Although with the advent of the LEDs the energy consumption in buildings can be reduced by 50%, there exists a potential for energy savings due to lighting controls. Moreover, lighting controls can ensure that the near zero energy requirements by EU can be achieved for near zero energy buildings (nZEBs). For this reason, more sophisticated lighting controls must be proposed in order to take full advantage of LEDs and their flexibility concerning dimming. This paper proposes the architecture of an embedded computer camera controller for monitoring and management of image data, which is applied in various control cases, and particularly in digitally controlled lighting devices. The proposed system deals with real-time monitoring and management of a GigE camera input. An in-house developed algorithm using MATLAB enables the identification of areas in luminance values. The embedded microcontroller is part of a complete lighting control system with an imaging sensor in order to measure and control the illumination of several working areas of a room. The power consumption of the proposed lighting system was measured and was compared with the power consumption of a typical photosensor. The functional performance and operation of the proposed camera control system architecture was evaluated based upon a BeagleBone Black microcontroller board.
