Abstract
A lighting device has an LED light source and a lens. The lens includes a light emitting surface arranged substantially parallel to a wall of a container when the device is attached to the wall, and a first light receiving surface. The first light receiving surface receives light that is emitted from the LED light source in a direction slanted with respect to the light emitting surface, and takes a concave surface configured such that a distance of the first light receiving surface to the light emitting surface increases from one end to the other end of the lens. The LED light source is disposed while being confronted with one end part of the lens.
