Lighting apparatus and lighting apparatus assembly using the same

摘要

A lighting apparatus (10) includes a light-emission unit (1) having plate shape; and a base unit (2) configured to be detachably attached thereto the light-emission unit (1). The base unit (2) has substantially rectangular shape. The base unit (2) includes a power supply rail (3) for supplying electricity to the light-emission unit (1) and a support section (20) supporting the light-emission unit (1). The power supply rail (3) has rail-shape and extending in a longitudinal direction of the base unit (2). The light-emission unit includes a luminescent panel (11), a control circuit configured to control lighting of the luminescent panel (11) and an electrically conductive connection terminal electrically connecting the control circuit to the power supply rail (3). The base unit (2) is formed so as to be capable of being attached thereto a plurality of the light-emission units along the longitudinal direction of the base unit (2). The connection terminal is connected to an arbitrary point of the rail-shaped power supply rail.
