  • Cold Cathode Fluorescent Lamps (CCFLs)
    . For an understanding of 3.0mm diameter CCFLs, which are increasingly found in LCD display modules, and to aid in the selection of a lamp diameter for a particular application, a comparison of photometric, electrical, and temperature characteristics are given for a 3.0mm and a 6.5mm lamp. Results of experimentation
  • Comparative Field-Test
    In an independent comparison of OBB's Lamp Housing with elliptical reflector vs. a competitor's condenser (lens/reflector) housing, a 100 watt Hg lamp was mounted in the OBB Lamp Housing, and a 350 watt Hg lamp was mounted in the competitor's conventional lamp housing. Both lamps were focused
  • Visible LEDs Application Notes
    The features of LED lamps become clear by comparison with tungsten filament incandescent lamps and discharge tubes in their light emitting mechanisms and structures.
  • CO2 balance sheet: aluminum versus alumina ceramics
    of energy-relevant processing methods. Substituting aluminum with alumina ceramics reduces CO2 emissions into our atmosphere by roughly a factor of two using a volume comparison. When you consider the weight of the end product, aluminum contributes about three times the amount of CO2.
  • Liquid Lens Miniature Imaging System for Handsets
    phenomenon, the liquid lens uses two isodensity liquids; one is an insulator while the other is a conductor. The variation of voltage leads to a change of curvature of the liquid-liquid interface, which in turn leads to a change of the focal length of the lens. In comparison to conventional auto-focus
