Yes, a window is typically non-luminous because it does not emit light on its own. Its purpose is to allow light to pass through it into a space, rather than generate light itself.
It's non-luminous
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.

The Earth is non-luminous, meaning it does not produce its own light. The light we see on Earth comes from sources such as the Sun, the Moon, and artificial lighting.
Some tables may be painted with luminous paint. Most are not luminous.

If the bulb is switched off, then we would call it non-luminous.
the types of non-luminous are bulb,candles ect
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.

A flashlight can be both luminous and non-luminous at the same time if it is turned on in a well-lit room. The flashlight itself emits light (luminous) while the ambient light in the room also contributes to the overall illumination (non-luminous).
Bodies which emit light are luminous bodies and those who don't emit light are known as non luminous bodies Example - stars are luminous bodies while planets are non luminous bodies Tube light is a luminous body while a chair is non luminous
A flashlight is luminous when it is turned on and emitting light. It is non-luminous when it is turned off and not emitting any light. So, a flashlight can be both luminous and non-luminous at different times depending on its operational state.
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
The two flames that flicker both non-luminous and luminous are a candle flame and a gas stove flame. When burning normally, these flames emit light due to combustion. However, if they are disturbed or lack sufficient oxygen, they can flicker and may become non-luminous.
