## Background
BACKGROUND OF THE DISCLOSURE
a) Field of the Disclosure
The invention relates to a technology field of driving mice away, and more particularly, to a green-light device for driving mice away, wherein the device can emit light with specific wavelengths to interfere with visions of mice such that the mice cannot forage and thus can be driven away. The device is adaptively used in kitchen, homes, factories, offices and so on.
b) Brief Description of the Related Art
Mice are harmful animals that can destroy the furniture or crops, steal food and spread diseases. A variety of traps and rat poisoning agents are used to remove the harmful animals, while a device is designed for driving mice away.
With regards to the device for driving mice away, the device traditionally utilizing an oscillator circuit to produce ultrasonic frequencies is put at a specific place. The traditional device drives mice away by an acoustic wave that causes mice feel discomfort. However, even though the traditional technology and product employing a general single-frequency ultrasonic transducer is able to produce a strong sound pressure and only output a pattern of a sound wave with a single frequency, the effect on driving mice away is reduced because the mice get used to the device having been used for a certain period of time. According to scientific studies, mice are nocturnal harmful animal mainly relying on hearing and smelling for chaotic foods or actions, and compared to the sense of hearing and smelling, mice have relatively bad sense of sight, which only detects specific wavelengths of light to determine whether to go out for action. No device is developed in this way for driving mice away and thus the technology can be improved.
Accordingly, for customer advantages, the inventor is devoted to a green-light device for driving mice away, wherein the device can emit light with specific wavelengths to interfere with visions of mice such that the mice cannot forage and thus can be driven away. This is the purpose of the invention.

DETAILED DESCRIPTION OF THE INVENTION
Illustrative embodiments are now described. Other embodiments may be used in addition or instead. Details that may be apparent or unnecessary may be omitted to save space or for a more effective presentation. Conversely, some embodiments may be practiced without all of the details that are disclosed.
Referring to FIGS. 1, 2 and 2a, in accordance with the present invention, a green-light device 1 for driving mice away includes a casing, a power plug 11 is at a backside of the casing, a switch 12 and power socket 16 are at left and right sides of the casing, a control knob 13, transparent window 14 and speaker hole 15 are at a front surface of the casing, and a control circuit 3 including a power conversion circuit 31 is in the casing.
Referring to FIGS. 3 and 4, the power conversion circuit 31 comprises a voltage regulating integrated circuit (IC) 32, an amplifying circuit 33, multiple green-light emitting diodes (LED) 34, a control knob 13, an ultrasonic frequency oscillator circuit 36 and a logical-determination circuit 35.
The power conversion circuit 31 is mainly a bridge rectifier, composed of four diodes, which can convert an alternate current into a direct current. Next, the converted direct current can be regulated by the voltage regulating integrated circuit (IC) 32 and then be amplified by the amplifying circuit 33 so as to be utilized by the green-light emitting diodes (LED) 34. In this embodiment, the amplifying circuit 33 can be a Darlington amplifying circuit composed of two transistors, two resistors, a diode and a capacitor. The green-light emitting diodes 34 are diodes capable of emitting light with specific wavelengths and are controlled by the logical-determination circuit 35 to be automatically turned on or off or to have been turned on for a long period of time.
Besides, the control circuit 3 may further include a negative-ion purifier switched by the control knob 13 to operate for different functions. By means of the ultrasonic frequency oscillator circuit 36 producing high-power ultrasonic waves that reflect back and forth in the indoor air or of the green-light emitting diodes (LED) 34 emitting light with specific wavelengths, mice can be prevented from moving nearby. The device is used not only to drive mice away but to serve as a small night lamp for illumination. Besides, the negative-ion purifier can create negative ions to purify the air and to clean the air from foods or other odors and thus the probability of enticing mice to come nearby can be reduced.
Besides, when the green-light device 1 for driving mice away is plugged into a socket, another electric appliance can be plugged into the power socket 16 on the casing. Thereby, other electric appliances can also be used and thus practicality for supplying power is good.
Accordingly, in accordance with the present invention, the green-light device for driving mice away includes the green-light emitting diodes emitting light with specific wavelengths to interfere with mice's determination of day or night such that the mice cannot forage and thus can be driven away.
