A circuit board provided with a receiving circuit built in the frame, which reproduces a video signal and an audio signal, a liquid crystal screen for a television provided in front of the frame, and the liquid crystal screen facing substantially the same direction as the liquid crystal screen. And a speaker provided on the machine frame, wherein a perpendicular line of the liquid crystal screen is inclined upward with respect to a bottom portion of the machine frame at least within a range of a viewing angle of the liquid crystal screen. It is a portable lighting device arranged as follows.

A second aspect of the present invention is the portable illuminating device according to the first aspect, wherein a vertical line of the liquid crystal screen is arranged to be inclined upward by 10 to 20 degrees with respect to a bottom portion of the machine frame.

[0007] Further, a portable lighting device according to claim 1, wherein a hood for the liquid crystal screen is provided around the liquid crystal screen.

[0008]

According to the above-mentioned structure, the lighting device and the television can be compactly combined, so that the lighting function of the lighting device body and the audiovisual information of the television receiver can be combined. In addition, when the bottom portion is set on a table or the like, the visibility of the liquid crystal screen is considerably reduced outside the range of the viewing angle, for example, the screen appears to be whitened. Since the liquid crystal screen is arranged to be inclined upward at least within the range of the viewing angle of the liquid crystal screen with respect to the bottom surface, the range of the viewing angle shifts upward by that amount, and the portable lighting device is moved by the bottom portion. Even if the liquid crystal screen is viewed obliquely from above and installed, since the viewpoint is within the range of the viewing angle of the liquid crystal screen, the phenomenon that the liquid crystal screen looks white and the like does not occur.

[0009] In particular, by arranging the perpendicular line of the liquid crystal screen at an angle of 10 to 20 degrees upward with respect to the bottom portion of the machine frame, the viewpoint for observing the liquid crystal screen from obliquely above is more reliably obtained. Since the viewing angle is within the range of the viewing angle of the liquid crystal screen, the visibility can be made more suitable.

Further, by providing the hood of the liquid crystal screen around the liquid crystal screen, the visibility of the liquid crystal screen is not deteriorated by external light.
