Thermal design is one of the most important issues in the development of compact self—ballasted fluorescent lamps as the demand for small yet powerful lamps is mounting. This paper proposes a simulation method that is based on a thermal network model for which a set of equations are developed. Some of the coefficients of the thermal network equations were determined experimentally using a simulated model lamp. The calculated temperatures are in good agreement with the measured temperatures. The work illustrates the usefulness of the proposed methodology in the design of compact self—ballasted fluorescent lamps.

The influence of artificial classroom light source’s colour temperature to students’ learning efficiency and physiology rhythm is the focus of this study. An experiment compares a subjects’ learning efficiency, asthenopia and brain fag under different luminance level of three typical colour temperatures from T5 fluorescent lamps and LED. Using comprehensive index ε and norm identification Ψ for quantitative evaluation and testing under different lighting environments, we determined the best colour temperature of two experimental light sources. We also determined the best combinations of illuminance value and the colour temperature that should be avoided in classroom lighting. Experiment shows that spectrum difference obviously effects comprehensive index ε and norm identification Ψ. For learning efficiency and health of people, there need to be improvement in the spectrum of fluorescent lamps and LEDs

Abstract Spent fluorescent lamps(SFLs) such as linear type lamp, compact type lamp and U-type lamp are used to estimate mercury distribution in the components of lamps. Determination of mercury concentration in the components of spent fluorescent lamp is performed by the DMA method. Mercury concentration in the components of spent fluorescent lamp can be varied with the manufactures of lamp. Mercury portion in phosphor powder and glass from any types of spent fluorescent lamp is estimated to be higher than 99% by the analysis of mercury distribution. Through mercury distribution in the components for SFLs, the mercury concentration in phosphor powder is much higher than that in other components regardless of the type of lamp. Hence, it is desirable that phosphor powder of spent fluorescent lamps should be controlled separately and safely.

Industrialized component wastes, regularly discarded by the society, are increasingly contributing to the environmental pollution. The glass of these lamps is contaminated with mercury, which a serious hazard due to conventional recycling by melting with other glasses. A possible solution could be its incorporation into a clay body to fabricate common fired ceramics such as bricks and tiles. The objective of this work is to characterize a type of glass to be incorporated into a clayey ceramic. The glass analyzed was obtained from fluorescent lamps, which was passed through mercury decontamination process and ground into powder. This glass powder was tested for X-ray fluorescence, DTA/DTG, optical microscopy, scanning electron microscopy and optical dilatometry. The results showed that the glass presents sintering and softening points around 650 °C and 800 °C, respectively. The chemical analysis indicated the presence of impurities in considerable amounts in the composition of the fluorescent lamp glass waste.

The increase amount of industrial wastes is becoming a serious worldwide environmental problem, which is aggravated by wastes containing toxic substances. This is the case of fluorescent lamps that use mercury vapor for light emission. At the end of their operational life these lamps should not be directly disposed to avoid the Hg toxic effects. Decontamination procedures take the Hg away but leave the other parts of the lamp as solid wastes. The mains part is the lamp glass, which finds many ways to be recycled. In the present work a fluorescent lamp glass waste was investigated as a possible material to be incorporated into a cement matrix as part of a civil construction concrete. Different amounts of waste up to 20 wt% were mixed with sand, gravel and cement to prepare concrete samples that were tested for the mechanical strength and water absorption in intervals of time until complete cure at 28 days. Although the waste failed to show pozzolanic activity, the incorporated concretes attended the required technical specifications.

Compact Fluorescent Lamp

<p><em>L</em><em>ighting is one of the human basic needs that must be fullfiled. Compact fluorescent lamps is the most used lamp as source of lighting. However, they contain mercury, which is classified as heavy metals, that can potentially harm the environment. Even as mercury container, many people didn't know that. Many people don't know the method to handle the broken or used compact fluorescent lamp. They just dispose the broken compact fluorescent lamp to trash without considering the effect of mercury contained.</em></p><p><em>Inverse Manufacturing concept is about designing product life cycle that aims to repair and reuse product components so that the negative impact can be reduced and minimized. In this research, the concept of Inverse Manufacturing is applied on handling the compact fluorescent lamp product in Bandung, West Java. The study is begun with designing the Inverse Manufacturing concept’s model by adding the step of collecting back (two scenarios), sorting, repairing, remanufacturing, and recycling into the life cycle of compact fluorescent lamp. The results of recycling rates of 15 Watt compact fluorescent lamp  (about 234 grams) starts from the lowest value,  and the maximum value are 27,51 % (64,366 grams),  and 27,61 % (64,609 grams). By applying this concept, the result are the reduction on the amount of compact fluorescent lamp waste dumped into the environment and the achievement of  the conservation of natural resources through the reuse of used components.</em></p>

<p>ABSTRACT<br />Lift net fishermen usually use fluorescent lamp as attractor to lure fish. As price of fuel rise, fishermen are forced to find another option to change their attractor into some much lower cost and more energy-save lamp, or in other words, to change into LED lamp. This research are providing evidence that sunked LED lamps can be utilized as a helper tools, and also determined the best time for catching fish in the lift net. Two lift net used in this research, one of them used sunked LED lamps and the other used ordinary fluorescent lamps. Lift net are operated as long as 20 nights, with four catching times per night, between 18.00-21.00, 21.00-00.00, 00.00-03.00, and 03.00-06.00. Results showed that LED lamps give a better result with 11 organisms successfully catch (287,6 kg), compared to ordinary fluorescent lamps with only six organisms (238,3 kg). The best time for catching with LED lamps are between 18.00-21.00 (121 kg), while between 21.00-00.00 (67,4 kg), 00.00-03.00 (46,9 kg) and 03.00-06.00 (52,3 kg).<br />Key words: fluorescent lamp, lift net, light emitting diode, Palabuhanratu,sunked lights</p><p>-------</p><p><br />ABSTRAK<br />Nelayan bagan biasa menggunakan lampu fluorescent sebagai atraktor untuk memanggil ikan.

The article is devoted to the description of experimental studies on the assessment of the hygienic efficiency of lighting conditions with light emitting diodes (LEDs) of the first and second generations when performing industrial work. In the course of the research work, an experimental lighting installation (ELI) was developed and installed, able to implement lighting options with LEDs and fluorescent lamps (FL). The state of the accommodative-muscular apparatus, the retina and the central link of the organ of vision was assessed; integral indicators of visual performance were studied. It was found that the illumination with LEDs does not have a negative effect on the organ of vision, the human body as a whole or indicators of visual performance. Changes in the functional indicators of the organ of vision occurring during the performance of visual work are within the corresponding boundaries of physiological fluctuations and are reversible. It was revealed that second generation LEDs create a more favourable light environment for performing visual work of a production nature. The practical significance of the results obtained was shown.
