Title:
LIGHTING APPARATUS AND IMAGE DISPLAY APPARATUS PROVIDED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2012/001998
Kind Code:
A1
Abstract:
Provided is a lighting apparatus and an image display apparatus provided therewith, wherein heat dissipation capability can be improved while maintaining structural strength, uneven brightness generated due to uneven heat distribution can be inhibited, and the image display apparatus can be made to be thinner. In a heat conductive member (6), a light-source holding section, which has a face facing a light-entering face of a light-guiding member, and a plate-formed section, which has a face facing a light-exiting face of the light-guiding member and a face facing a heat dissipation member (5), are formed adjacent to each other. At the light-source holding section, a light source (7) is arranged on the face facing the light-entering face of the light-guiding member, in a direction facing towards the light-entering face, and the face of the plate-formed section facing the heat dissipation member (5) is made to come in contact with the face of the heat dissipation member (5) facing the light-guiding member. At the plate-formed section, the center of gravity of the plate-formed section is biased in both a direction parallel to the light-entering face and a direction parallel to the light-exiting face.
