Energy-saving lamp

How can the Ecodesign Directive be further developed to handle the RISKCYCLE-topic So far, pollution issues are involved in the context of product evaluation and the derivation of product standards, but rather in the sense of LCA to capture the energy side and the other relevant environmental indicators. The topic of mercury in compact fluorescent lamps (CFL) has made it clear that pollution issues can be quite important in the context of this Directive. However, relevant limits for energy saving lamps were first set by a waste-related regulation, namely the Annex of the WEEE Directive [7]. 

Lighting and lamp fittings, lamp bases of energy saving lamps... 

Luminescent materials have changed the world. Energy saving lamps, many kinds of displays and modern medical equipment all rely on luminescent materials and it is hardly imaginable that large scale application of luminescent materials started only slightly more than 100 years ago (for an overview see e.g. Ref [5.198]). 

In energy-saving lamps of the so called trichromatic type, the blue color comes from strontium phosphate, doped with europium, the red from a yttrium-europium mix-... 

Light emitting diode (LED) lamps show great promise as a future star of energy-saving lamps for general llghfing. 

PBT is applied in a wide range of products in the lighting industry. Well known is the lamp base of the energy saving lamp, where PBT is selected for a combination of properties heat resistance, dimensional stability, colour stability and laser markability. 

CFL (Compact Fluorescent Lamp) In lighting, CFL stands for compact fluorescent lamp, a type of light bulb that provides considerable energy savings over traditional incandescent light bulbs. 

Crystal fields of uneven (ungerade) symmetry are able to lift the parity selec- ion rule. The reader should not underestimate the importance of such a, seemingly-Kademic, statement there would be no color television, and no energy-.saving lumi-lescent lamps without uneven-symmetry crystal fields, as we will see later. 

The production of ketene by this method has no significant environmental impact. The off-gases from the ketene furnace are either circulated to the furnace and burned to save energy or led to a flare system. The reaction can also be carried out at 350—550°C in the presence of alkaH-exchanged zeoHte catalysts (54). Small quantities of ketene are prepared by pyrolysis of acetone [67-64-1] at 500—700°C in a commercially available ketene lamp (55,56).
