The purpose of the present invention is to provide an LED lighting device that allows luminous regions to be adjusted easily. This lighting device is provided with at least an LED light source (3) and an optically-transparent protective cover (1) spaced from the LED light source (3) and positioned so as to face light-emitting regions (33) of the LED light source (3), and is characterized in that a prism sheet (4), which is provided with prisms (42) internally or at least on one of the surfaces, is provided between the LED light source (3) and the protective cover (1). Due to this configuration of the LED lighting device, the light-emitting regions can be adjusted easily. |
