A clip provided by the present invention includes an insert portion that is inserted into an insertion hole formed in a flat-shaped chassis and that engages with the chassis, and a collar portion that is formed in a flat shape around the circumference of the insert portion. When the insert portion is inserted into the insertion hole, the collar portion and the chassis clamp at least one light emitting board that is positioned in contact with the chassis, and the thickness of the collar portion is set to be equal to or less than an amount of protrusion of a light emitting portion formed protrudingly from the light emitting board.

Clip and backlight assembly

In a projection apparatus projecting an image by using light of a light source contained in a housing, there is provided a light source mounting device in which when the light source in the housing is replaced, the light source is mounted and the light source is raised from a position of an opening used for taking in and out a light source to a normal position to make positioning, so that the light source in the housing can be simply replaced.

Projection apparatus

A display apparatus and its cooling method in which the optical assemblies can be prevented from being smudged by dust entered into the apparatus so that an excellent image can be obtained and the apparatus can be cooled sufficiently with the apparatus including a housing having a screen on its front surface and a closed structure, an optical block having a closed structure and coupled with the housing in a closed fashion allowing air to circulate between the housing and the optical block. Further, the display apparatus includes a light source, a first cooling device for cooling the light source and a second cooling device for cooling the optical block. At least the optical block is arranged to have a closed structure and is cooled by air circulation.
