    摘要: A lighting device includes a light source configured to radiate light toward a floor from a ceiling, a reflecting mirror provided around the light source, and shading angle setting element configured to define a range in which the light from the light source is radiated by setting a shading angle with respect to the light radiated from the light source. The light source, the reflecting mirror and the shading angle setting element are covered by a translucent cover. The translucent cover has an in-line transmittance. An in-line transmittance of the translucent cover of a position corresponding to an optical axis of the light source and an in-line transmittance of the translucent cover of a position deviated from the optical axis are different from each other.

    摘要: A fluorescent lamp lighting apparatus according to the present invention comprises an initial illuminance correction control circuit which sets a fluorescent lamp to an initial illuminance correction control lighting mode, a switching portion which changes the fluorescent lamp from the initial illuminance correction control lighting mode to an external control dimming mode when a predetermined external dimming signal is detected, and a control portion which gradually dimming so as to achieve a dimming level of a switched mode when switching the initial illuminance correction control lighting mode and the external control dimming mode, and control so as to achieve a dimming level corresponding to a cumulative lighting time of the fluorescent lamp when the changed mode is the initial illuminance correction control lighting mode.
