ABSTRACT OF THE DISCLOSURE A lighting device such as a rear-spoiler stop lamp in which the percentage of utilization of the available light and the illuminating effect produced by the lamp are enhanced despite the convexity of the face lens of the lamp, and the entire face lens is uniformly irradiated with the light. The device includes a device body composed of a base and a face lens and includes a large number of juxtaposed light-emitting diodes. The face lens is convexly curved at a prescribed curvature. The inside surface of the face lens is formed with light control portions corresponding to respective ones of the light-emitting diodes arranged in such a manner that the rays of light emitted from the diodes are directed in prescribed directions by the light control portions. The intervals between the light-emitting diodes and the intervals between the respective light control portions are changed depending on the curvature of the face lens so that the intervals are a maximum at the center of the lens and gradually decrease toward both the two ends.
