Abstract

A lighting assembly 1 for a street light has a plurality of lighting elements such as LEDs connected to a circuit board 3, the circuit board being removably attached to a heat sink. The circuit board may be in thermal communication with the heat sink and attached by a fixing element such as a screw that extends through an aperture in the circuit board. The circuit board and the fixing element may be electrically insulated from the heat sink by an insulating locating element 12 configured to receive the fixing element. The locating element may be located in a recess in the heat sink. There may be an electrically insulating silicone layer 15â between the heat sink and the circuit board. The heat sink may have a curved surface and thermally conductive projections, pads and vanes. An electrical connector connects the circuit board to a street light power supply.
