Embodiment Construction

[0059] based on Figure 1 to Figure 5 and Figure 8 One embodiment of the present invention will be described below.

[0060] figure 2 The perspective view which shows the lamp unit 1 which concerns on this embodiment. lamp unit 1 with Figure 6 The lamp unit 24 described also includes cold cathode tubes 41 , 41 . In addition, there may be other than two cold cathode tubes, and the number is arbitrary. The lamp unit 1 is roughly a unit in which components are supported on a resin holder 44 extending along the tube axis direction of the cold cathode tubes 41 , 41 , and both ends of the cold cathode tubes 41 , 41 are held by holders 40 , 40 . Furthermore, the lamp unit can be configured such that the cold cathode tube is held at the lead end without the resin holder. The holder 40 is made of rubber, for example. The resin holder 44 holds the reflector 42 of the lamp unit 1 inside. The resin holder 44 also covers the outer side of the lamp unit 1 in the tube axis directi...

Abstract

In a lamp unit (1), a layer structure of a reflective member (42) is directly led out to the light emission side of the lamp unit (1) from square U-shaped one end of that portion of the reflective member (42) that is closest to that side of the reflective member (42) from which electric power is supplied to the lamp unit (1). The led-out portion is turned back 180 degrees in the direction of leading out of the layer structure, and this forms a conductive section (2). The conductive section (2) has a screw hole (2a) for connecting the reflective member to another object. Even if the reflectivemember is fixed for electrical conduction to another object by a screw, a reflection layer is less likely to peel off.

Description

technical field [0001] The present invention relates to a lamp unit used as a light source unit of a device, and a lighting device and a display device including the lamp unit. Background technique [0002] image 3 A perspective view of a conventional transmissive liquid crystal display device 100 viewed from the rear side is shown. However, the illustration of the outer casing of the liquid crystal display device 100 is omitted. In this figure, a lamp unit 24 serving as a backlight is inserted into an inner space along one end 100 a of the liquid crystal display device 100 . Figure 5 A schematic cross-sectional view (A-A line cross-sectional view) is shown when the liquid crystal display device 100 is cut along a plane perpendicular to the side end portion 100a. [0003] This cross-sectional structure includes a backlight unit 20 and a liquid crystal panel 25 as lighting devices. The backlight unit 20 is provided on the rear side of the liquid crystal display device 10...
