Definitions
- the present invention relates to a lighting device, a display device including the lighting device, and a television receiver including the display device.
- a display device that does not emit light by itself for example, a display device that uses a liquid crystal display panel, is usually combined with a lighting device that illuminates the display panel from behind.
- Various types of light sources such as cold-cathode tubes and light-emitting elements are used as the light source of this type of lighting device.
- Light emitting elements include light emitting diodes (hereinafter referred to as “LEDs”), organic electroluminescent elements, inorganic electroluminescent elements, and the like, but LEDs are currently the mainstream.
- the light source of the illumination device described in Patent Document 1 is also an LED.
- an LED 122 is mounted on a mounting board 121 and a lens 124 that covers the LED 122 is attached to the mounting board 121 as shown in FIG.
- the mounting substrate 121, the LED 122, and the lens 124 constitute a light emitting module mj.
- the lens 124 is in the shape of a hemispherical dome having a uniform wall thickness, and transmits light emitted from the LED 122 without being refracted so much. Therefore, when the LED 122 is facing upward as shown in FIG. 12, the proportion of light traveling in a direction close to vertical increases.
- the light source is an LED.
- a plurality of LEDs are arranged on a substrate to form a surface light source, and the diffusion plate is irradiated with light emitted from the surface light source. Protrusions for supporting the diffusion plate are dotted on the substrate.
- the LEDs forming the surface light source are usually arranged in a grid pattern.
- the first possible arrangement position of the support pins is the center of the grid.
- FIG. 6 shows such an example. Although FIG. 6 is a plan view, only the support pin 101 is depicted as an image viewed from obliquely above. The support pins 101 are surrounded by LEDs 102 on all sides, and all of them are kept equidistant.
- FIG. 7 shows the luminance surface of the diffusion plate 103 illuminated by the LED 102 of FIG.

- the support pins 101 are surrounded by the LEDs 102 on all sides.
- a shadow 101 ⁇ / b> S extending in six directions appears on the luminance surface of the diffusion plate 103. If the density of the LEDs 102 is increased and the intervals in the row direction are reduced as shown in FIG. 10, a cross-shaped shadow 101S having a shape along a diagonal of the rectangle is generated as shown in FIG. In any case, such shadows cause luminance unevenness on the diffusion plate, and when the illumination device is used as a backlight of the display device, the display image quality is impaired. Therefore, it is necessary to eliminate it as much as possible.
- the present invention has been made in view of the above points.
- diffusion is performed.
- the object is to reduce the shadow cast by the support pins that support the plate on the diffuser plate and to make the uneven brightness of the diffuser plate less noticeable.

- the light emitting module includes a diffusing lens that covers the light emitting element.
- the diffuser lens is arranged so that the amount of light emitted from the light emitting element is increased in the lateral direction. If the diffuser lens is present, the shadow of the support pin is easily emphasized. According to the above, the shadow has a long and narrow area, and the luminance unevenness of the diffuser is less noticeable.
- the support pins are arranged at equidistant positions from the light emitting modules on both sides.
- a dark shadow is not formed only on one side of the support pin, and the shadow is not noticeable because the shadow has the same darkness on either side.
- a mounting board on which the light emitting element is mounted supports the support pins.
- the positional relationship between the light emitting module and the support pin can be set accurately, and the set positional relationship can be constantly maintained. Even if the mounting board can be attached to a chassis with different dimensions due to the model change, the positional relationship between the light emitting module and the support pin can be carried over to the chassis of a different model as it is, so there is no need to worry about the placement of the support pin. .
- At least a portion of the support pin that is irradiated with light emitted from the light emitting module has a surface with high light reflectance.
- the light emitted from the light emitting module is not easily absorbed by the support pins, so that the light emitted from the light emitting module can be fully used for the illumination of the diffusion plate.

- the light emitting element is an LED.
- a display device including the illumination device having the above-described configuration and a display panel that receives light from the illumination device is configured.

However, since it is inevitable that uneven brightness occurs if high-brightness LEDs are arranged sparsely, lenses with high light diffusion performance (such lenses are referred to as “diffuse lenses” in this specification). Are preferably used in combination.
- FIG. 13 is a graph showing how the illuminance (unit Lux) differs depending on the irradiation direction between a single LED and an LED with a diffusing lens.

- an LED with a diffusing lens it is possible to widen a region where illuminance of a certain level or more can be ensured and set the peak of illuminance at an angle different from the optical axis. It goes without saying that the illuminance pattern in the figure can be changed in any way by the design of the diffusing lens.
- FIG. 14 shows a collective image of the luminance of a plurality of LEDs.
- the solid line waveform represents the luminance of the LED with a diffusion lens
- the dotted line waveform represents the luminance of a single LED.
- the horizontal line in the waveform indicates the width of the waveform (half-value width) at a luminance that is half the peak value.
- each waveform can be widened, so that it is easy to make the luminance as a whole as a flat shape as shown by a solid line above the figure.
- each waveform has a height, while the width is narrow, and it is inevitable that a wave is generated in the luminance obtained by collecting them. As described above, an image having uneven brightness is not preferable. Therefore, the use of an LED with a diffusion lens is almost inevitable.

Due to the presence of the leg portion 24 a, a gap is generated between the mounting substrate 21 and the diffusion lens 24. The LED 22 is cooled by the airflow flowing through the gap. If the problem of heat dissipation can be solved, an integrally molded light emitting module in which LEDs are embedded in a diffusing lens can be used.
