## Abstract

An illumination device capable of being controlled by blow includes a casing, a light emitting module, a driving circuit board and a blow sensing module. At least one air hole is formed on a periphery of the casing. The light emitting module is disposed on a top of the casing. The driving circuit board is disposed in the casing and electrically connected to the light emitting module. The blow sensing module is disposed in the casing, electrically connected to the driving circuit board and used for sensing blow through the at least one air hole. 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The illumination device of claim 1, wherein the casing is made of metal material, the cover is made of ceramic material, the casing contacts the cover partially so as to conduct heat generated by the light emitting module from the casing to the cover and then dissipate the heat out of the cover.

### Claim 3 (depends on 1)

The illumination device of claim 1, wherein the cover is transparent.

### Claim 4 (depends on 1)

The illumination device of claim 1, further comprising a power storage module disposed in the casing, electrically connected to the driving circuit board, and used for supply power to the driving circuit board during power failure.

### Claim 5 (depends on 4)

The illumination device of claim 4, wherein the driving circuit board switches on the light emitting module in full brightness or switches off the light emitting module according to the number of blows sensed by the blow sensing module during power failure.

### Claim 6 (depends on 1)

The illumination device of claim 1, further comprising a lamp socket fixed on a bottom of the casing.
