Title: LED STREET LAMP
Abstract:
The invention relates to an LED street lamp (1), at least comprising a socket (2) in the form of a closed cassette, an electrical supply unit (3) coupled to the socket, and a roof (4), which covers the socket (2) and is spaced apart from the socket. The socket (2), which comprises at least one hermetically isolated module (2.1), is designed in a multifunctional manner as a heat sink and as part of an optical unit, which optical unit comprises at least one reflector (2.2), one LED (2.3) having an associated controller, and one transparent cover (2.4). The socket (2) comprises channels (2.8) or air slots (2.8), which extend between the front side (2.6) and the back side (2.7) in the region of the wall (2.5) of the socket, i.e., over the entire height of the socket, and which produce, in interaction with cooling fins (2.9) arranged on the outer faces of the socket and/or on the inner faces of the socket (2) facing the socket interior, a suction or chimney effect or convection, which nearly completely removes the heat produced in the socket interior by the operation of the LEDs (2.3).
