Abstract
A light source unit is used in a multiply combined manner, and includes a light source element having a substrate and one or more light emitting elements disposed on the substrate. The light source unit is configured such that when a plurality of the light source units are arranged in cascade, the light source element in the light source unit comes to in electric connection with another light source element in an adjacent light source unit. Thereby, the plurality of light source units may emit light at the same time. Thus, the structure similar to rod-shaped light source such as CCFL is achieved.
Claims24
A light source unit used in a multiply combined manner, comprising:
- a light source element having a substrate and one or more light emitting elements disposed on the substrate, wherein
- the light source unit is configured such that when a plurality of the light source units are arranged in cascade, the light source element in the light source unit comes to in electric connection with another light source element in an adjacent light source unit.
A light source device comprising:
- a plurality of light source units, each having one or more light emitting elements and electrical connection portions, and
- an arrangement restriction structure restricting arrangement of the plurality of light source units so that the plurality of light source units are arranged in cascade, wherein
- the plurality of light source units are electrically connected to one another via the respective electrical connection portions of the light source units.
A display apparatus comprising:
- an illumination device;
- and
- a display section displaying an image with use of illumination light from the illumination device,
- wherein the illumination device has a plurality of rod-shaped light sources, each of the rod-shaped light sources having an optically transparent cylindrical tube with a hollow space inside thereof and having a plurality of light source units emitting light, and
- the light source units are arranged in cascade inside the optically transparent cylindrical tube, and the light source units adjacent to each other are electrically connected to each other.
