“…The system architecture, requirements, and implementation of a light control system for entertainment and media production were discussed in [4]. In [5], the authors considered light control for individual activities assuming that each user carries a wireless illumination sensor. Most of the above works use illumination sensors to provide feedback for light control.…”

“…Illuminator provides a systematic process to obtain this information via a light characterization phase. In [27], the authors used a similar approach to ours, in that the light is controlled in a closed-loop fashion. However, sensor locations are assumed to be fixed at grids, infeasible in most real cases.…”

We present the design and implementation of a unique sensing and actuation application-the Illuminator: a sensor network-based intelligent light control system for entertainment and media production. Unlike most sensor network applications, which focus on sensing alone, a distinctive aspect of the Illuminator is that it closes the loop from light sensing to lighting control. We describe the Illuminator's design requirements, system architecture, algorithms, implementation and experimental results. The system uses the Illumimote, a multi-modal and high fidelity light sensor module well-suited for wireless sensor networks, to satisfy the high-performance light sensing requirements of entertainment and media production applications. The Illuminator system is a toolset to characterize the illumination profile of a deployed set of fixed position lights, generate desired lighting effects for moving targets (actors, scenic elements, etc.) based on user constraints expressed in a formal language, and to assist in the set up of lights to achieve the same illumination profile in multiple venues. After characterizing deployed lights, the Illuminator computes optimal light settings at run-time to achieve a user-specified actuation profile, using an optimization framework based on a genetic algorithm. Uniquely, it can use deployed sensors to incorporate changing ambient lighting conditions and moving targets into actuation. Experimental results demonstrate that the Illuminator handles various high-level user requirements and generates an optimal light actuation profile. These results suggest that the Illuminator system supports entertainment and media production applications.

“…There are many papers describing occupancy-based adaptive control systems monitoring the illuminance distribution resulting from the luminaire output and incident daylight, combined. The output of the luminaires is then adjusted in order to achieve a desired target illuminance [8][9][10][11][12][13] . Such smart lighting clearly has major advantages in terms of efficiency, lighting quality and controllability by the user.…”

“…There are many papers describing occupancy-based adaptive control systems monitoring the illuminance distribution resulting from the luminaire output and incident daylight, combined. [6][7][8][9][10][11] In all of these cases, the total output of the individual light sources is controlled. Modern light utilisation research is epitomised by innovations in software, rather than inventing hardware to achieve similar or improved functionality.…”

Countless approaches to optimise lighting conditions for indoor and outdoor applications are described in the literature by adaptive dimming schemes or control algorithms. Those methods rely on adapting the emitted flux of individual luminaires in order to adjust lighting conditions to varying circumstances. Complex illumination requirements are tackled by controlling the output of every independent luminaire. In this case, the innovation is rather in software than in hardware, and such approaches are limited by how the LED fixtures can be manipulated. Lighting fixtures with a tuneable radiation pattern are rare, or these fixtures are rather large. This paper introduces a compact lighting system with a collimated light beam of which the beam direction and beam divergence can be adjusted electronically. To realise this optical functionality, a focus tuneable lens and rotatable mirror are combined with two custom-made aplanatic lenses in front of a compact, high-brightness LED. This paper elaborates the optical design of this novel illumination system and discusses the experimental performance of the realised demonstrator. The system functionality is validated by comparing the experimental lighting performance to optical simulations conducted with ray-tracing software. With the proposed system, a fast and flexible adaptation of the generated illumination distribution is possible.
