Illumination device capable of being controlled by blow

An illumination device capable of being controlled by blow comprising:

• a casing, at least one air hole being formed on a periphery of the casing;
• a light emitting module disposed on a top of the casing;
• a driving circuit board disposed in the casing and electrically connected to the light emitting module;
• a blow sensing module disposed in the casing, electrically connected to the driving circuit board, and used for sensing blow through the at least one air hole;
• and
• a cover having an opening, the casing being disposed in the cover and a part of the casing being exposed within the opening, such that the at least one air hole is located within the cover and exposed within the opening;
• wherein the driving circuit board controls the light emitting module to emit light in different brightness according to a number of blows sensed by the blow sensing module.
