ILLUMINATION DEVICE, DISPLAY DEVICE, AND TELEVISION RECEPTION DEVICE

摘要

A backlight device 12 includes: a chassis having a bottom plate and side plates that stand towards the front of the bottom plate from the edges of the bottom plate, the face on one side of the bottom plate being a light-output part; an LED substrate disposed on the front surface of the bottom plate; LEDs 24 arranged on a plate face oriented toward the light-output part of the LED substrate and arranged so that the light-output part is on the light-emitting side thereof; a plurality of diffusion lenses 27 for covering the light-emitting side of the plurality of LEDs and diffusing the light from the LEDs 24; a first reflecting sheet 29 provided with light source insertion holes through which the LEDs 24 are inserted at positions corresponding to the LEDs 24, the first reflecting sheet being laid over the front surface of the bottom plate and over the LED substrate; and a second reflecting sheet 30 arranged so as to protrude in the direction in which the side plates rise, the ends of the second reflecting sheet 30 being held between the first reflecting sheet 29 and the plurality of diffusion lenses 27, the second reflecting sheet 30 being held over the first reflecting sheet 29 by coming in contact with the diffusion lenses 27 and the first reflecting sheet 29.

主权项

1. An illumination device, comprising:
a chassis having a plate-shaped portion and side plates that rise up from edges of the plate-shaped portion on one surface thereof; a plurality of light source substrates disposed on the one surface of the plate-shaped portion; a plurality of light sources disposed on the light source substrates, the light sources outputting light in a direction of light output; a plurality of diffusion lenses respectively covering the plurality of light sources to diffuse light from the light sources; a reflective sheet disposed on the one surface of the plate-shaped portion and the light source substrates, the reflective sheet having light source insertion holes that correspond in position to the light sources to insert the light sources therethrough; and a flat spring member over the reflective sheet, the flat spring member generally protruding outward from a plane defined by the reflective sheet and having a pair of ends that oppose each other, one of the ends being held by the reflective sheet and one of the plurality of diffusion lenses, another end of the flat spring member being held by the reflective sheet and another of the diffusion lenses so that the ends of the flat spring member are respectively in contact with said one and another diffusion lenses and the reflective sheet to secure the reflective sheet onto the light source substrates, the flat spring member being reflective.
