Claims

[Scope of utility model registration request]

A device body with an opening on the lower surface, a linear lamp having one or more mutually parallel light-emitting shafts attached to the device body so as to be exposed at the opening, and a lower part of the lamp. One louver element, which is a flat plate, is arranged parallel to the axis of the light emitting part of the lamp, and the other louver element, which is formed in the same shape as this louver element and is orthogonal to the louver element, is used to open the opening in the main body of the appliance. a louver that partitions the area into grids and allows the lamp to face each grid, and a specular reflector that is installed directly above the louver element parallel to the axis of the lamp light emitting part so as to be parallel to the louver element. The specular reflector has a shape formed by a part of a parabola whose focus is the axis of the light emitting part of the lamp closest to the specular reflector and whose axis is tilted downward by 35° to 55°. , A lighting fixture with a louver, characterized in that the louver has a light shielding angle of 30 degrees or less and has a matte finish on the surface.
