Abstract
A method and apparatus for illuminating a heated area on a cooktop panel includes a light ring peripherally aligned about a burner under the cooktop panel, a gasket for resiliently retaining the tube beneath the cooktop panel and a support for resiliently engaging the gasket against the panel. Preferably, the light ring is a tube recessed within the gasket to avoid direct contact with the cooktop panel surface. The gasket may also restrict illumination to a channel portion of the gasket. Alternatively, the tube can be coated to avoid illumination in directions other than the area exposed to the panel. The gasket forms a convenient masking tool for delineating the surface area of the tube that is to be exposed while shielding other exterior surfaces of the tube. Both the illuminator and the method for illuminating the burner are simplified when the gasket includes a support flange beneath the tube retaining socket.
