STREETLIGHT

A streetlight comprises at least one lighting unit (1) which has a housing (2) equipped with a light source (3), a partially translucent bottom cover (4), a top cover (5), and a fixture (6). The light source (3) is composed of at least one LED module (7) which comprises the LEDs (8) and the controlling and supplying means mounted on a printed circuit board (9). The lighting unit (1) has a void pocket (10) bounded by front wall (11) and lateral walls (12) of the housing (2) and the top cover (5), wherein at least one heat sink module (13) is fixed with thermal connection to the housing. The number of the heat sink modules is adjusted to the number of the LED modules, preferably it is an integer proportional to aggregated power of the LED modules. The LED modules are arranged in a rectangular array (14), and then the number of the heat sink modules is adjusted, preferably proportional, to the area of the rectangular array. The lighting unit has a movement sensor (15) and/or an infrared sensor (16), and/or at least one light sensor (17). If a photovoltaic panel (23) is attached directly to the lighting unit, then the number of additional heat sink modules installed in the void pocket is an integer proportional to the heating power produced by the photovoltaic panel. The fixture of the streetlight has a means, preferably an actuator, to adjust the longitudinal tilt angle (±), and the transversal tilt angle (²). The streetlight may comprise two or more lighting units connected to common fixture (6Y, 6T).
