Effective Application of Plasma Lighting Facility Based on Electrodeless Sulfur Lamp for Electrical Regeneration
EFFECTIVE APPLICATION OF PLASMA LIGHTING FACILITY BASED ON ELECTRODELESS SULFUR LAMP FOR ELECTRICAL REGENERATION Tetyana I. Frolova Kharkiv National University of Radio Electronics, 14 Nauky Ave., Kharkiv, 61166 UKRAINE Today, due to the intensive depletion of fossil resources on Earth, there is a need to use renewable energy sources. The most interesting is the photoelectric conversion of solar energy into electrical energy. Although the Sun is the largest source of energy on Earth and supplies 99.98% of the total energy of our planet, however, the intensity and spectral distribution of its radiation depends on geographical location, climatic, weather, and seasonal conditions, etc. Therefore, in the process of our life, artificial light sources are often used. Modern light sources must satisfy a number of parameters, combining high luminous efficiency and efficiency of generated radiation (a wide range of spectral distribution and color rendering), durability and environmental friendliness with low cost and variety of applications fields. The plasma lighting facility with a sulfur lamp is a powerful light source having a quasi-solar emission spectrum and providing light fluxes of 140 klm, and a color temperature of about 6400 K. Also the electrodeless lamp with microwave excitation has the ability to control the radiation power, which allows imitating the modes of sunrise and sunset. Electrodeless sulfur lamps can be used together with other electronic devices for creating the power energy-efficient lighting systems. It is proposed to use a lighting facility based on an electrodeless sulfur lamp with microwave excitation combine with solar batteries that are located indoors (for example, greenhouses). -

Printed Optics LED Light Bulb Technology Material Parameters of Optical Encapsulates Emission Characteristic & Efficiency
www.led-professional.com ISSN 1993-890X Review LpR The leading worldwide authority for LED & OLED lighting technology information Mar/Apr 2013 | Issue 36 Printed Optics LED Light Bulb Technology Material Parameters of Optical Encapsulates Emission Characteristic & Efficiency EDITORIAL 1 Challenge - Electronics The change from traditional light sources to LEDs is, in many ways, a big step. Manufacturers have to adapt their product portfolio and lighting designers and installers have to figure out how the new light source will behave. A lot of research, studies and tests are being done to gain more knowledge when it comes to dealing with semiconductor light. By the end of this decade there will be significant improvements that are concentrated on the parameters and implementation of the LED. This development is very important but the really big challenge, when looking at lighting installations in general, is ELECTRONICS. The reason for this is that the weakest element in a system limits its overall performance. The life-time of electronic drivers is mainly determined by the use of electrolytic capacitors. The temperature degradation of these components will often reduce life-time under real conditions below the 50,000 hours that are expected of LEDs. In addition, the failure rates of the electronic modules, consisting of 50 to 100 single components, are not equal to the failure rates of single LEDs or LED strings. Electronics are even being challenged on a system level. The number of electronic ballasts for fluorescent lamps that can be connected to a circuit breaker is well defined. The problem is that the inrush or start-up currents are much higher now and those limits don’t correspond properly with the electronic LED drivers. -

PASCAL MAUSSION M. GEORGES ZISSIS Rapporteurs : M. BABAK NAHID-MOBARAKEH, UNIVERSITÉ LORRAINE M. MOUNSIF ECH CHERIF EL KETTANI, UNIVERSITE DU HAVRE Membre(s) du jury : Mme BETTY SEMAIL, UNIVERSITE LILLE 1, Président M. GEORGES ZISSIS, UNIVERSITE TOULOUSE 3, Membre M. PASCAL DUPUIS, UNIVERSITE TOULOUSE 3, Membre M. PASCAL MAUSSION, INP TOULOUSE, Membre Abstract Metal halide lamp is one kind of the most compact high-performance light sources. Because of their good color rendering index and high luminous efficacy, these lamps are often preferred in locations where color and efficacy are important, such as supermarkets, gymnasiums, ice rinks and sporting arenas. Unfortunately, acoustic resonance phenomenon occurs in metal halide lamps and causes light flicker, lamp arc bending and rotation, lamp extinction and in the worst case, arc tube explosion, when the lamps are operated in high-frequency bands. This thesis takes place in the context of developing electronic ballasts with robust acoustic resonance detection and avoidance mechanisms. To this end, several envelope detection methods such as the multiplier circuit, rectifier circuit, and lock-in amplifier, are proposed to characterize fluctuations of acoustic resonance. Furthermore, statistical criteria based on the standard deviation of these fluctuations are proposed to assess acoustic resonance occurrence and classify its severity. -
