摘要:
An object of the present invention is to stably fix a light source board without using any screw. A backlight unit 12 according to the present invention includes an LED board 18 including an LED 17 as a light source, a chassis 14 that stores the LED board 18 and has an opening 14b through which light from the LED 17 exits, and a holding member 20 that extends in at least one direction along a plate surface of the LED board 18 and is fixed to the chassis 14 so as to hold the LED board 18 together with the chassis between the holding member 20 and the chassis 14.

A lamp clip 18 includes a main body 27, a lamp gripping portion 28, a first mounting portion 30 and a second mounting portion 31. The main body 27 is mounted to a chassis 14 that houses a plurality of tubular cold cathode tubes 17. The lamp gripping portion 28 is provided on a surface of the main body 27 opposing the cold cathode tube 17 so as to grip the cold cathode tube 17. The first mounting portion 30 protrudes from the main body 27 so as to extend toward the chassis 14 and to be in a first mounting hole 32 formed in the chassis 14 so that a rim of the first mounting hole 32 is sandwiched between the first mounting portion 30 and the main body 27. The second mounting portion 31 protrudes from the main body 27 so as to extend toward the chassis 14 and to be inserted in a second mounting hole 33 formed in the chassis 14 so that a rim of the second mounting hole 33 is sandwiches between the second mounting portion 31 and the main body 27. The second mounting portion 31 has a width different from a width of the first mounting portion 30 in a mounting direction to the chassis 14.

A backlight unit 12 includes a chassis 14, a plurality of cold cathode tubes 18, an optical member 16 and a plurality of support members 20. The chassis 14 has an opening on a light exit side. The cold cathode tubes 18 are light sources arranged in a parallel layout and housed in the chassis 14. The optical member 16 is arranged on the light exit side outer than the cold cathode tubes 18 so as to cover the opening of the chassis 14. The support members 20 are arranged in a parallel layout along a parallel arrangement direction of the cold cathode tubes 18. The support members 20 are formed such that support positions of the optical member 16 are relatively closer to the cold cathode tubes 18 around the center and relatively farter from the cold cathode tubes 18 near the edges. The cold cathode tubes 18 are arranged at relatively smaller intervals around the center and at relatively larger intervals near the edges.

A lighting apparatus (12) has a plurality of tubular light sources (17) arranged in parallel and a light reflective member (40) arranged at the opposite side of the light emission side of the tubular light sources. Arrangement of the tubular light sources is configured to have narrow interval sections (17A) with relatively narrow-spaced arrangement intervals and wide interval sections (17B) with relatively wide-spaced arrangement intervals. On the light reflective member, openings (50) are formed such that an aperture ratio equivalent to a formation ratio of the openings (50) to a whole area of the light reflective member (40) becomes greater in the narrow interval sections (17A) than in the wide interval sections (17B). The lighting apparatus is characterized by such a configuration.

A lighting device achieves cost reduction and suppression of power consumption with suppressing the occurrence of a lamp image. A lighting device 12 includes: a plurality of linear light sources 17 disposed in parallel; a chassis 14 housing the linear light sources 17 and having an opening 14b through which light from the linear light sources 17 exits; and an optical member 15a facing the linear light sources 17 and disposed to cover the opening 14b. The linear light sources 17 are arranged at relatively small intervals in a light source high-density region LH and arranged at relatively large intervals in a light source low-density region. An optical member 15a includes a light reflection portion 50 configured to reflect light from the linear light sources 17 at least in a portion overlapping with the light source low-density region LL.

The backlight unit (49) of a display device (69) having a liquid crystal display panel (59) is provided with a chassis (41), a diffuser plate (43) supported by means of the chassis, and a light source which irradiates the diffuser plate (43) with light. In the light source, a plurality of light emitting modules (MJ), each of which includes an LED (22), a diffusing lens (24) covering the LED, and a built-in reflecting sheet (11) disposed between a mounting substrate (21) and the diffusing lens, are disposed in matrix on the chassis which supports the diffuser plate. The built-in reflecting sheet has a light reflection ratio higher than that of the mounting substrate.

Lamp clips for holding lamps with different juxtaposition pitches can be disposed accurately and easily at positions corresponding to the lamps. Indexes 41 and 42 indicative of the locations of lamp clips 31 and 32 are formed on a chassis 11 where lamps 21 to 24 are juxtaposed with different juxtaposition pitches. The lamp clips 31 and 32 comprise: plate-like bases 311 and 321; holding portions 312, 312, 322 and 322, which are provided at one face of the bases 311 and 321, for holding the lamps 21 to 24; and markers 313 and 323 corresponding to the indexes 41 and 42. Since the operator disposes the lamp clips 31 and 32 with the markers 313 and 323 corresponding to the indexes 41 and 42, the lamp clips 31 and 32 can be arranged accurately and easily.

An LED unit U of the present invention includes an LED 17 that is a light source, a diffuser lens 19, a board reflection sheet 23 and a restriction member 27. The diffuser lens 19 is provided to face a light emitting surface 17a of the LED 17. The board reflection sheet 23 is provided to face a surface of the diffuser lens 19 that is closer to the LED 17 and is configured to reflect light. The restriction member 27 projects from the diffuser lens 19 toward the board reflection sheet 23 and restricts positional relationship between the diffuser lens 19 and the board reflection sheet 23.
