PROBLEM TO BE SOLVED: To enable a lighting device to be adapted for a case in which light of light source is distributed above in view of a simple outside appearance and another case in which light is not distributed above, realize a low manufacturing cost and further enable a uniform feeling in design to be applied to a place where two different kinds of lighting devices under upward light distribution state.SOLUTION: A shading plate member 6A or a glass plate 6B acting as non-inflammable member is selectively adhered and arranged at an inner side surface of the second surface 32 of a cover 3 formed by a translucent resin plate covering an emergency light source 1 together with a main body 2. A predetermined clearance D1 is arranged between the first surface of the cover 3 and the emergency light source 1. When the shading plate member 6A is applied, light of the emergency light source 1 is not distributed above the lighting device 10. When the glass plate 6B is applied, light of the emergency light source 1 is distributed above the lighting device 10.SELECTED DRAWING: Figure 3 |
