On June 6, 2011, the EU Ecolabelling Committee issued a new â€œFlower of Ecologyâ€ labeling regulation for light bulbs (2011/331/EU). This regulation applies to all sources of light with a luminous flux of â‰¥ 60 lumens and â‰¤ 12 000 lumens for general illumination, with the exception of the following:
The new regulations determine the â€œecological flowerâ€ standard for light bulbs in terms of light performance, longevity, mercury content, and hazardous substance content. Some of the requirements are as follows:
Single-ended Double ended efficiency 10% better than the lumen per watt value according to Class A 10% better than the lumen per watt value according to Class A Life (hours) 15 000 20 000 Lumen maintenance 80 % at 9 000 hours 80 % at 9 000 Mercury content (mg) < 1,5 < 3,0 Switching cycle Greater than the life of the lamp (in hours) Color rendering index Greater than 85 Color tolerance 3
In addition, the regulations also specify the requirements for hazardous substances, plastic parts, packaging, user manuals, etc. Companies that apply for eco-labels must also comply with social responsibility regulations.
TÃœV SÃœD, a well-known testing and certification organization, offers a wide range of testing and certification services for different markets in the world. For the EU market, TÃœV SÃœD can provide companies with a complete solution for ERP directives and help companies apply for the â€œEco Flowerâ€ label and the UK â€œESTRâ€ label. For the US market, TÃœV SÃœD is an Energy Star certification body accredited by the US Environmental Protection Agency (EPA) to provide ENERGY STAR certification services for LED lighting products. In addition, TÃœV SÃœD can provide testing and certification services for California Energy Efficiency Regulations (CEC).
TÃœV SÃœD has introduced world-class optical testing equipment such as Labsphere and Bentham in the United Kingdom. It is equipped with an integrating sphere system, a distributed photometer system, an optical radiation safety system and various other auxiliary equipment. Product manufacturers provide one-stop optical performance testing services, including light and color parameters such as luminous flux, efficacy, light distribution, chromaticity coordinates, color temperature, color rendering index, color space distribution, etc., and according to IEC 62471 Photobiological safety testing.
These controllers eliminated the need for rewiring and adding additional hardware for each new configuration of logic.
The new system drastically increased the functionality of the controls while reducing the cabinet space that housed the logic.
The first PLC, model 084, was invented by Dick Morley in 1969.The first commercial successful PLC, the 184, was introduced in 1973 which was designed by Michael Greenberg.
