Title: Light-source support mechanism, lighting device, and liquid-crystal display device
Inventor: TERAKAWA DAISUKE
IPC: F21V19/00
Filed: 2007-09-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a light-source support mechanism in which the occurrence of dark spaces is suppressed by reducing low-temperature parts of linear light-sources during start-up, and also to provide a lighting device in which optical unevenness during start-up is reduced, and a liquid-crystal display device.  <P>SOLUTION: The light-source support mechanism is provided with line support stands 26 respectively having a top part 26a further upwardly protruding than the lower end of a cold cathode tube 21 so that each line 27 is hung on the top parts 26a of the line support stands 26. Each line 27 is provided while alternately contacting with each top part 26a of each line support stand 26 and the lower end of the cold cathode tube 21 along an alignment direction of the line support stands 26. By configuring in such a manner, a tensile force of each line 27 is applied to the cold cathode tube 21. Vibration or noise breakout of the cold cathode tube 21 is suppressed thereby. Since a contact area between each line 27 and the cold cathode tube 21 is small, it prevents heat transfer from the cold cathode tube 21, thereby suppressing the occurrence of low-temperature parts, particularly, immediately after start-up. The occurrence of dark spaces is then suppressed.  <P>COPYRIGHT: (C)2009,JPO&INPIT
