DEVELOPMENT AND RESEARCH OF SPECIAL LUMINAIRE SYSTEMS Relevance of the research When Lithuania were joined into the European Community it has become necessary to use lighting devices corresponding to requirements of the European Community – ENEC norms. Taking into account the specificity of given devices in Lithuania and other new EU countries they should be steady against low temperatures, humidity, acts of vandalism, to be suitable for the illumination of industrial buildings and to fulfil the requirements of low prices of the new incorporated countries. Recently new comprehensive ENEC norms (EN European Norms, EC Electrical Certification) for luminaires were drawn up and effectively introduced by the European Union. As a result, the production of a wide range of electrical operating equipment was discontinued due to the inconsistency between technical parameters of produced equipment and new norms. Such equipments were not allowed to be marketed. Therefore it has become necessary to develop luminaires capable to fulfil the increased quality requirements of the European Union. Their development should also taken into account due to the targets of product responsibility (§ 22) laid down in the Act for Promoting Closed Substance Cycle Waste Management and Ensuring Environmentally Compatible Waste Disposal introduced in 1996 also should be taken into account extensively the aspects of ecological efficiency. In the past, plastic luminaire systems belonging to a higher... [to full text]
