If the lamp for an oven were in a cool location, away from the oven's heat, and the light from said lamp were conveyed to the inside of the oven through a fiber optic wire, then it would be possible for the oven's lamp to be a compact fluorescent or an LED -- something not normally possible in an oven,
because those types of lights are heat sensitive.
glowing potatos?

However, there is a existing piece of technology which might be utilised to provide a simpler and cheaper solution; it's called a "mirror" ... |
|
|
When you say "a" mirror, do you mean an air filled tube, lined with mirrors to prevent the walls of the tube from absorbing the light? |
|
|
I'm not necessarily against that solution, but will it be as effective at preventing the oven's heat from reaching the lamp? |
|
|
Air is generally a better insulator than glass, but only if convection can be prevented. |
|
|
And while air is free, and mirrors are cheap, a mirrored tube may require quite a few mirrors... plus, it will take up more bulk than an optical fiber. |

Would it not be simpler to just cook luminous food? |
|
|
//luminous food// Feasable, probably <link> I was hoping,
though, for a luminous version of shoefly pie called firefly
pie. |

it would never ever pay off financially or in terms of energy. |
|
|
Um, but doesn't a traditional oven lamp's Tungston filament glow at around 250 oC (500F)?

from the perspective of the bulb it is no more than a moderately hot day. enclosures and other lighting components are designed to get very hot. A 425* oven is well within design tolerances for the bulb itself. The base and the wiring are likely much cooler, insulted from the direct heat of the element and able to radiate into the airspace of the casement. |
