“…The LS radiation parameters may be controlled using signals transferred to input of the microcon- The network in our lighting system is based on IEEE802.15.4 standard and its ZigBee specification [20,21]. Low signal-to-noise ratio allows the signals to co-exist successfully with alternative sources of radiation at the same frequency (Wi-Fi, Bluetooth).…”

The work is devoted to the creation and study of high-power AlGaInN LED source with emission wavelengths (460–480) nm for pumping of solid-state lasers. The electrical, spectral, power and thermal characteristics were studied in a wide range of currents, continuous and pulsed modes. The design of LED matrices, which provides a tight “packing” of LEDs, their electrical commutation, efficient heat removal and a power supply for a wide pulse range has been proposed. The developed emitter comprises the most powerful and efficient to date LE Q8W (Osram) LEDs and is intended primarily for pumping Ti:Sapphire laser, the absorption band of which is well matched with the emission spectrum of the used LEDs. The achieved optical pumping power density in the pulsed mode is ~25 W/mm2, which corresponds to the lasing threshold.

“…They have not justified this additional network cost in terms of convenience and power savings, thus leaving this area open for further improvement. Andre Gloria et al have carried out a performance analysis of various communication protocols that are currently available for use in sensor networks [10]. It is clear from their work that the IEEE 802.15.4-based ZigBee protocol is the best choice for an indoor building automation application.…”

ZigBee standard is the popular communication protocol for wireless sensor networks (WSN) and Internet of Things (IoT) networks. An energy efficient WSN technology is a good choice for an IoT based lighting control technology. This article is a comparative analysis for finding the quality of service parameters provided by the different topologies of ZigBee for a wireless networked lighting control system. In order to estimate the energy consumption in ZigBee topologies for lighting automation, this work analyses the star, mesh, and tree topology-based WSN with two routing protocols Adhoc on-demand distance vector (AODV) and dynamic source routing (DSR). Lighting automation using wireless control networks with sensor-actuator nodes in a laboratory is considered as the test scenario. The applicability of ZigBee topologies for IoT-based lighting automation is discussed by the evaluation of performance parameters like average jitter, throughput, end-to-end delay, and energy model.
