description A lighting fixture includes a heat sink having a first mounting portion attached to a housing. A first circuit board containing LEDs is mounted to a first side of a second mounting portion of the heat sink. A second circuit board include an LED 5 control circuit is mounted to a second side of the second mounting portion. A multi layer circuit board includes a heat-dissipating core bonded to first and second dielectric substrates, which are bonded to first and second electrically conductive layers. An electrical conductor extends through a through-hole in the board to electrically connect the first and second conductive layers. An electrical insulator inside the through-hole 10 electrically isolates the core from the conductor. A transparent cover is shaped to cause downwardly projecting light rays emitted from the LEDs to be refracted more than upwardly projecting light rays. The cover also includes vertically extending projections for horizontally refracting light. 14 1 0FIG--,2
