“…During experimentation it is found that once again the LED tube lights give the highest efficacy among all tube lights t the tune of 84 to 118 lumens / watt as compared to just 26 and 30 lm/W by earlier technology fluorescent lamps. The specifications from the various manufacturers ie s theoretical values and compared with the values that observed during testing of the lighting fixtures, it is found that the actual vales differ from the rated values as shown in above tables (2)(3)(4)(5)(6) and graphs (3)(4)(5).…”

This study involves the various indoor illumination systems used in an engineering institution in the coastal town of Karnataka, India. The various types of illumination systems used currently are incandescent lamps, CFL lamps and fluorescent tube lights. Incandescent lamps are being used in washrooms of college building, CFLs in hostel corridors, hostel toilets and tube lights in offices, class rooms, laboratories and hostel rooms. For the experimental study a test rig was prepared with the luminaries currently used in the institution. Incandescent lamps of 10 W, 40W, 60 W, 100 W and 200 W, CFL of 9 W, 11 W, 15 W, 20 W, 35 W and LED bulbs of 4.7 W, 9 W, 10 W, 12W, 23 W were used in the test rig. Tube lights used are electronic choke, T8 of 36 W, T 12 of 40 W and LED tube lights of 4 W, 8 W, 20 W, and 22 W were used. This institution has 3 academic blocks A, B and C as well as two hostel buildings one for boys and the other for girls. The total installed illumination systems found are as follows. A block 5600 W, B Block 1464 W, C block 1,440 W, Boys hostel 3,200 W, Girls hostel 1,994 W and hence the total installed illumination systems used are of 11,710 W. As the institution is located in rural place the voltage variation was observed to be from 218 V to 245 V during the study. The incandescent lamps were found consuming 50% more power than the rated wattage, CFL were consuming 37% more power than rated wattage and LED lamps 7 % more power than rated power. The study concludes that by using new technology luminaries, we can conserve energy, environment with a simple payback period of less than an annum. The illumination equipment was bought during commencement of the institution during 2012 and have lost efficacy over the years.

“…In [8], they mentioned that the factors affecting are sky conditions and weather, numbers and location of the sensors, type of use and occupancy. Apart from the abovementioned, the design illuminance level is also one of the main factors of these as results finding in [2,47,48].…”

“…Based on this fact, the energy consumption needs to be reduced for economic and environmental benefits. There are several strategies can be considered: converting low energy efficient lamp technologies to high energy efficient lamp technologies, such as light emitting diode (LED) [2], occupancybased control and daylight-based control [3] and scheduling-based control [4]. In literature, LED lamp technology has a prominent energy efficient lamp among other lamp technologies due to its special characteristic: high color temperature and efficacy as well as less power consumption [5,6].…”

<p>Artificial lighting consumed significant amount of electrical energy in commercial buildings. Therefore, intelligent control strategies are widely implemented to reduce the lighting energy consumption. This paper presents comprehensive review of the current sensing-based strategies (i.e. occupancy, daylight and mixed), sensors placement methods (i.e. occupancy and light) and factors affecting the performance of the lighting control strategies. Based on literature survey, the sensors placement methods can be categorized into three approaches: fixed, mathematical equation and optimization. The state-of-the-art of these approaches are discusses in details. It found that, the optimization-based approach capable to find the optimal sensor placement (numbers and positions) effectively. Moreover, the mixed strategy can be produced the highest energy savings up to 95% compared with other strategies. The occupancy pattern and building characteristics are the main factors to contribute higher energy savings of sensing-based strategies in commercial buildings. </p>

“…Only ESLs will be used in future smart lighting systems, then there is an increasing interest in studying the new devices in their large applications. The optimal lighting system design in different indoor applications of ESLs have been investigated by considering several constraints and objectives: cost saving, energy efficiency and management, functional suitability, system integration, people satisfaction, and quality of lighting [31][32][33][34][35][36][37][38]. Moreover, it is important to point out the different innovative solutions in the modern agriculture consist on the development of facilities LED lighting technology.…”

Energy-saving lamps are equipped with converters enabling high energy efficiency at the cost of injecting very distorted currents on the mains. The problem is more complex in the emerging smart-lighting scenario where these lamps are also used to perform additional tasks. Harmonics mitigation at the lamp level is expensive; consequently, an optimal lighting system design aiming at reducing both costs and current distortion of the whole lighting system is necessary. A tool able to emulate the current drawn from the lamps is necessary for optimal design. Such a tool has also to consider the fluctuations of the voltage on the mains that usually occur throughout the day. In this perspective, a parametric PSpice circuit is proposed and the netlist is reported in this work. Moreover, the simple procedure to be adopted for computing the parameters is also described. The validation has confirmed the ability of the proposed circuit in emulating the current drawn from various CFLs and LED lamps under different supplying voltage.
