An oven having an illumination device for illuminating an oven cavity, the illumination device, comprising:
- a light source having a printed circuit board (PCB) arranged exterior to the oven cavity;
- a light guide extending from the PCB to direct light into the oven cavity via an inlet defined in the frame;
- and
- a metal cylinder surrounding the light guide at the inlet to protect the PCB from microwave leakage.
A light device for illuminating an oven cavity, the light device, comprising:
- a light emitting diode (LED) in communication with a printed circuit board (PCB) arranged exterior to a frame defining the oven cavity;
- a light guide extending from the LED to direct light into the oven cavity via an inlet defined in the frame;
- and
- a cylinder surrounding the light guide at the inlet to protect the PCB against microwave leakage.
A blocking cylinder for covering an inlet for a light device illuminating an oven cavity configured to block exposure to leaking microwaves, the blocking cylinder, comprising:
- a first portion configured to receive a distal end of a light guide, the first portion having a cylindrical shape and a first diameter;
- and
- a second portion extending from the first portion and configured to receive a gasket for further receiving the light guide, the second portion having a cylindrical shape and a second diameter.
