According to the machinery statistics by Ministry of Economy, Trade and Industry (METl), the total of domestic light bulb production in 2006 was 1,101 million (88.50/0 year-on-year). Production for general purpose illumination light bulbs and halogen light bulbs accounted for 122 million (99.2o/o y/y) and 45 million (96.30/o y/y), respectively. The total of fluorescent lamp production was 988 million (114.90/0) and the production of general purpose fluorescent lamps excluding backlights accounted for 367 million (1 O1 .70/0 y/y).Further, HID Iamp production was 10 million (106.30/o yly). What is noteworthy regarding such lamp production is that, similar to the previous year, the sales volume (amount) of lamps for general illumination exceeded 1000/o against the previous year, indicating a steady shift to high value added products. Major lighting exhibitions in 2006 included the Light + Building Trade Fair held in Frankfurt in April and the Light Fair International 2006 held in Las Vegas, U.S.A. in May, both of which demonstrated signs of acceleration toward energy saving, high efficiency and resource saving. As for incandescent lamps, products filled with larger atomic weight gases aiming at higher efficiency/longer life are becoming the mainstream. As for new technologies, it was experimenta[[y demonstrated that infrared radiation can be suppressed by processing micro cavities to metal plates made of tungsten, tantalum, etc. For fluorescent lamps, straight and circular f[uorescent lamps achieving a longer life/higher luminous flux maintenance factor continued to be widely developed/launched again this year. For compact fluorescent lamps, energy saving/high efficiency products, multifunctional type products combined with LED and new shaped products were launched. As to HID Iamps, ceramic metal halide lamps with high efficiency, improved color rendering, Ionger life and higher [uminous flux maintenance factor were commercialized one after another. Numerous studies and analyses, on discharge models were reported. Further, studies on ultra high-pressure mercury lamps as light sources for projeu tors are becoming the mainstream of HID Iamp refated researches. For highpressure sodium lamps, many studies on plant growing and pest control utilizing low insect attracting aspects were also reported in 2006. Additionally, for discharge lamps, the minimum sustaining electric power for arc tubes employed in electrode-less compact fluorescent lamps was investigated. For Hg-free raregas fluorescent lamps, a luminance of 10,000cd/m2 was attained by a I meter-long external duplex spiral eiectrode prototype using Xe/Ne barrier discharge. As to startup circuits, the commercialization of energy saving and high value added products mainly associated with fluorescent lamps and HID Iamps are becoming common. Further, the miniaturization of startup circuits for self electronic-ballasted lamps has advanced. Speaking of the overall light sources and startup circuits in 2006 and with the enforcement of ROHS in Europe in July, the momentum...
