摘要： Uneven brightness is less likely to occur in lighting devices at low cost. A backlight unit 12 includes LEDs 17, a chassis 14 having a bottom plate 14a and housing the LEDs 17, and an LED drive controller 24 controlling drive of the LEDs 17. The LEDs 17 are arranged in a matrix in row and column directions (X-axis direction and Y-axis direction) along the bottom plate 14a, forming respective LED groups 25 each along the row direction. The LED groups 25 include a middle LED group 28 and an end side LED group 29. The middle LED group 28 is located in a middle portion of the bottom plate 14a in the column direction group and the end side LED group 29 is located closer to an end of the bottom part from the middle portion group. The LED drive controller 24 controls light of at least one of the middle LED group 28 and the end side LED group 29 such that the end side LED group 29 has relatively high brightness and the middle LED group 28 has relatively low brightness.

摘要： Provided is an illumination apparatus which prevents variations in the distance between the light-receiving surface of a light guide plate and a light source. Also provided is a display device which incorporates the illumination apparatus. The light guide plate, which constitutes a backlight unit, receives light through a light-receiving surface with the light-receiving surface oriented toward the light being emitted. In the backlight unit, pillars extend to intersect the direction of emission from an LED and are thus brought into contact with a device-carrying board and the light guide plate, which are superposed one on the other, thereby securing the device-carrying board and the light guide plate.

摘要： A backlight unit 12 includes LEDs 16, light guide plates 18, an air layer AR and a scattering structures. Each light guide plate 18 has a light entrance surface 34 and a light exit surface 36. The light entrance surface 34 faces the corresponding LED 16 and light from the LED 16 enters through the light entrance surface 34. The light exit surface 36 through which light exits is arranged along an arrangement direction in which the LED 16 and the light entrance surface 34 are arranged. The light guide plates 18 are arranged in a parallel layout so as to be parallel to the light exit surface 36 and perpendicular to the arrangement direction. The air layer AR is provided between the adjacent light guide plates 18 and has a refraction index lower than that of the light guide plates 18. The scattering structures are provided in side-edge surfaces 31a that are interfaces between the light guide plates 18 and the air layer AR. The scattering structures are configured to scatter light inside the light guide plates 18. With this configuration, uneven brightness is less likely to occur.

摘要： A feeding apparatus for a wide metal strip, wherein a plurality of through-holes are formed with predetermined gaps in a length direction and a width direction, into a cutter and pulls narrow metal strips formed by cutting the wide metal strip between the through-holes in the length direction so that through-holes are formed along only the length direction. The feeding apparatus includes a feeding-in apparatus that is provided on an entrance side of the cutter that feeds the wide metal strip into the cutter and a pulling-out apparatus that is provided on an exit side of the cutter that pulls out the narrow metal strips, which have been cut out by the cutter. A linking member drives the feeding-in apparatus and the pulling-out apparatus in concert so that the wide metal strip is fed into the cutter together with the narrow metal strips out being pulled out from the cutter.
