<P>PROBLEM TO BE SOLVED: To provide a light-emitting device in which a cold cathode tube is adopted as a lamp, and even if an inverter is adopted as a lighting device, countermeasures are made against heat generation at a low cost. <P>SOLUTION: A hollow device casing 2 having a diffusing plate 7 used in a state of standing up, a plurality of U-shape cold cathode tube lamps 11 to irradiate light to the diffused plate 7 is arranged in parallel in the interior of the device casing 2, and an inverter 4 to turn on the U-shape cold cathode tube lamps 11 is arranged, and the inverter 4 is arranged in the lower range of the inside of the device casing 2, and the U-shape cold cathode tube lamps 11 are arranged in inverse U-shape so as to make both end parts 11c-1, 11c-2 of the lamps provided with the electrode parts may become facing downward. <P>COPYRIGHT: (C)2004,JPO |
