An Investigation On The Lighting Systems Of The Manufacturing Floor In Electronics Industry

Kamoy, Leyla 01 January 2010 (has links) (PDF)
Required illumination levels in an electronics manufacturing facility were studied in order to provide feedback for architects and engineers. The study was carried out for the production floor of an electronics company in Ankara. The space considered was a Printed Circuit Board Assembly (PCBA) and Surface Mount Device (SMD) production department. The selected area was subdivided into different areas according to required illumination levels for each year. These levels were determined according to the specific work types over the total area according to each individual department. Data compiled by the field survey was analyzed and evaluated for investigating the relation of the potential effectiveness of the lighting systems regarding time, together with illumination levels needed for specific work areas. Changes in the sizes of areas needing various illuminance levels over past years were analyzed. It was found that there had been a decrease in the total required illumination levels.

The Design and Manufacture of a Light Emitting Diode Package for General Lighting

Krist, Michael S 01 January 2010 (has links)
Lighting technologies have evolved over the years to become higher quality, more efficient sources of light. LEDs are poised to become the market standard for general lighting because they are the most power efficient form of lighting and do not contain hazardous materials. Unfortunately, LEDs pose unique problems because advanced thermal management is required to remove the high heat fluxes generated by such relatively small devices. These problems have already been overcome with complex packaging and exotic materials, but high costs are preventing this technology from displacing current lighting technologies. The purpose of this study is to develop a low-cost LED lighting package capable of successfully managing heat. Several designs were created and analyzed based on cost, thermal performance, ease of manufacturing, and reliability. A unique design was created which meet these requirements. This design was eventually assembled as a prototype and initial testing was conducted. This thesis reviews the design process and eventual results of the LED package design.

Světový trh s osvětlovací technikou a pozice ČR na tomto trhu / Global lighting market and a position of the Czech Republic in this market

Šimetková, Tereza January 2015 (has links)
This thesis is focused on the analysis of the global lighting market and the assessment of the current position of the Czech Republic in this market. The first part is devoted to the theoretical introduction in the field of lighting technology. Furthermore, the thesis deals with the relation between lighting market and energy sector, especially with regard to energy efficiency policy. The market analysis is concentrated primarily on general lighting, which forms the largest and the most important lighting market segment. The development of the Czech lighting market is then discussed in the context of the global as well as the European market. Additionally, the thesis includes analysis of current trends in lighting technology and research conducted among manufacturers of lighting.
