Patent ID: 8680753

Claim:
A spotlight for outdoor use, the spotlight comprising: a base for connecting to an electrical socket; a housing shaped for sealing engagement with a mains voltage PAR38 style outdoor lamp holder to protect the electrical contact area of the based and the socket from water; a step-down device for reducing an incoming mains voltage to an LED voltage, the step-down device being sealed within the housing to protect the step-down device from water; an LED chamber containing one or more LEDs powered by the LED voltage, the LEDs having a combined light output equivalent to a PAR38 reflector lamp; spacers extending from the housing to the LED chamber, the spacers defining an air gap separating the step-down device from the LED chamber, the air gap allowing free-flowing ambient cooling air to flow between the step-down device and the LED chamber, wherein the spacers are integral with a lid over the step-down device and contain passages which provide paths for leads from the step-down device to the LEDs; and one or more heat-sink elements in contact with the LED chamber and the air gap for conducting heat away from the LEDs, whereby the spotlight is a substitute for a PAR38 reflector lamp; wherein a lower portion of the LED chamber has in its protected centre a vent opening which provides ventilation to inhibit condensation in the chamber.
