The invention relates to an illumination system (10) for illuminating outdoor regions (5), such as a sports ground, for example. The illumination system (10) comprises a plurality of lamps (10) comprising a plurality of illumination elements (20), arranged in a non-co-planar manner on a frame (50) or in at least one housing (11), for generating a plurality of light beams (25) having an optical axis (23) substantially in the direction of the outdoor regions (5) and at least one shielding element (21) arranged in an upper region (22) of the plurality of illumination elements (20), arranged so as to shield at least one part of the plurality of light beams (25) in the direction of the horizon (8) and thereabove away from the ground.

The invention relates to an illumination device comprising a domeshaped, cylindrical lens (7) having an optical focal line (19) and a plurality of light sources (3) arranged along the focal line and configured to emit light during operation. Said lens being disposed to receive and to deflect said light as a light beam having an angle y in a transverse direction, wherein 0′<=.sub.7<=30′. In transversal cross section the cylindrical lens comprises a central portion (21) flanked by a first side portion (23) and a second side portion (25). The illumination device further comprises an axially extending screen (27) disposed adjacent to the first side portion; and an axially extending diffuser (33) provided at the second side portion.

A power tool includes an output assembly, a housing, and an illumination device. The housing includes a main body, a grip, and a power supply connection portion. The power supply connection portion is configured to connect a power supply device. The main body and the power supply connection portion are respectively disposed at two ends of the grip. The illumination device is mounted to the power supply connection portion and includes a light-emitting element and a shield covering the light-emitting element. The shield has a light emission surface allowing light to be emitted therethrough. The power tool has a central plane, and a ratio of a size of the light emission surface in a width direction perpendicular to the central plane to a size of the power supply connection portion in the width direction is greater than or equal to 0.5 and less than or equal to 1.
