Claims

[Scope of utility model registration request]

A casing that houses an electronic circuit, an air filter attached to an air intake port of the casing, a light emitting circuit that generates light, and a light emitting circuit that is provided on the opposite side of the light emitting circuit and that generates the light through the air filter. A photosensitive circuit that generates a clogging detection signal when the clogging detection signal is less than a predetermined value, a switching circuit that generates a lighting current when the clogging detection signal is supplied, and a lighting circuit that lights the lighting when the lighting current is supplied. An air-cooled electronic device comprising: a clogging detection section having a clogging detection section;
