Claims

[Claims for Utility Model Registration] (1) A tubular light emitting source, a reflecting plate disposed at a constant interval from the tubular light emitting source and reflecting light from the tubular light emitting source, and the tubular light emitting source and the reflecting plate Semi-opaque films that are arranged facing each other at regular intervals and have shading so that the illuminance of the transmitted light is almost uniform, corresponding to the illuminance distribution of the direct light from the tubular light source and the reflected light from the reflector. or a uniform shielding sheet in which one or both of the shielding films for shielding light consisting of dots or lines are arranged on a transparent sheet, and a holding means for maintaining a constant distance between the uniform shielding sheet and the tubular light emitting source and the reflector. A uniform illumination unit comprising: and. (2) a tubular light emitting source, a reflecting plate disposed at a constant interval from the tubular light emitting source and reflecting light from the tubular light emitting source, and a reflecting plate disposed at a constant interval opposite to the tubular light emitting source and the reflecting plate; The light consists of a semi-opaque film, dots or lines having shading so that the illuminance of the transmitted light is almost uniform, corresponding to the illuminance distribution of the direct light from the tubular light source and the reflected light from the reflector. Either one or both of the shielding films to be shielded are arranged on a transparent sheet, a uniform shielding sheet, a diffuser plate disposed on the entire surface of the panel and diffusing at least the transmitted light that has passed through the uniform shielding sheet, and the tubular light emitting source. A lighting panel comprising a lighting panel body that covers a reflection plate and a uniform shielding sheet together with a diffusion plate, and configured to illuminate a transmitted light type film disposed in front of the diffusion plate, comprising: the tubular light emitting source; reflector and uniform shielding sheet,
An illumination panel comprising a uniform illumination unit comprising at least one of the tubular light emitting sources, a reflector, and a uniform shielding sheet.
