Abstract

Good lighting is fundamental to the success of any sporting event. Regardless of whether a sport is played indoor or outdoor be it a leisure activity or a world championship, at nighttime or in daylight, live telecast on TV or not - the primary demand for lighting remains the same. A consistent level of evenly spread illuminance across the full field of play is essential. Again the objects of observation (ball, puck, etc) move fast against a background of non uniform luminance, their angular sizes vary in a wide range, and the players, referees (who are observers of the objects) move in random directions. The direction of play is also important. According to these Groups, Classes and direction of play of different types of sports have different guidelines of lighting which are specified in CIE and IESNA. It is important that appropriate type and quality of lighting is used for three fundamental reasons. The reasons are to ensure the safety of the players and other people involved in the game; to provide better viewing for the spectators; to ensure that the significant amount of money spent on the installation has been utilized. The Inter- National Cricket Council (ICC) has its individual standards for cricket stadium lighting. The Board of Cricket Control in India (BCCI) follows those standards for cricket stadium lighting in India. These standards include lighting parameters, like Horizontal and Vertical Illumination, Uniformity, Glare Rating for cricket stadiums.

Keywords

Sports Lighting Criterion, BCCI Standards, Narrow and Medium Beam Angle Luminaires, Aiming of Luminaires, Switching Schemes.

Abstract

The primary function of road lighting is to keep the safety of the people. The road lights should provide good visibility condition and reduce potential hazards of accidents. Again the road lights glow from dusk to dawn through out the year consuming remarkable amount of energy. Thus this study on road lighting was done to make it more visually acceptable and energy efficient one. The standardization of Road Lighting has also been revisited here. Few quick fix recommendations are mentioned here for betterment of road lighting, maintaining energy saving aspect in metro cities like Kolkata.

Keywords

Road Lighting Standards, Mesopic Photometry, Energy Efficiency, Time Scheduling, Low Wattage Lamp, Roadway Classification.

Abstract

For the last two decades, technology growth has made it possible to bring 'Automation' in different spheres of life. This paper is basically an automation of Lighting Control. Lighting is the most valuable aspect of everyone's daily life and it consumes a big percent of electrical energy. So lighting engineers must look after good lighting as well as with less consumed power. Automation of lighting helps to reduce the use of unnecessary light as well as consumed power.

Keywords

Lighting Control, Automation of Lighting.

Abstract

To comfort today's severe energy crisis the demand-side management is the only solution today. The demand-side management actually means the most efficient application of electrical loads. This is the drive-force to haunt for energy efficient electrical loads, and to search for an energy efficient light source, idea of using a semi-conductor device as a light source named Light Emitting Diodes (LED) was originated. The acceptability of white LEDs for general purpose illumination increases with the introduction of high brightness white LEDs having better lumen output. This paper describes the techniques which have been adopted to increase the lumen output from a LED. The photometric measurement issues are still very crucial in case of LEDs because of lack of standardizations. This paper also discusses the applications point of view of LEDs, its lumen maintenance, life span and finally the scopes of further research & development of it.

Abstract

Indian market is now observing an intense penetration of High Frequency Electronics Ballasts (HFEB) in consumer applications for lighting like CFL & FTL lamps. The use of HFEB has been further enhanced manifold with popularity of T5 FTL lamps & its consumer fittings. This work reveals that majority of the consumer range HFEB are flouting the basic BIS/IEC safety norms. This study further points out that there is hardly any incremental cost or any high technology requirement to make a competitive, safe & socially accountable consumer range of HFEB.

Abstract

Lighting accounts for 17.5% of the total energy consumed in India as against 5% in developed countries. In recent years, electronic ballasts with fluorescent lamps and CFL lamps have attracted research interests because of considerable advantages if compared with the electromagnetic ballasts commonly in use. Due to ever-increasing requirement for power quality, international standard has been published and it provoked new research efforts worldwide.
