PROBLEM TO BE SOLVED: To provide a lighting apparatus usually acting as a lighting device, assuring lighting enabling a countermeasure action for a short time when a power loss occurs at a power failure at night and the like and subsequently having an indicator function for confirmation of its position by phosphorescent of luminous function material.SOLUTION: This invention relates to a light guide plate type lighting apparatus having luminous function in which salient protrusions 3 for taking out light from a light guide plate are formed into semi-spherical lens shape, and light from the light guide plate is collected to a luminous function layer to increase illumination intensity of exciting light for luminous material. A luminous light dispersion reflection sheet 2 is of 2-layers structure of a luminous material containing organic resin layer having luminous function and a dispersion reflection layer containing particles dispersed and reflected that are arranged in sequence from a side of light from the light source 15 incident to the reflection sheet 2.SELECTED DRAWING: Figure 11 |
