Abstract
The utility model discloses a light-controlled alarm clock which comprises an alarm clock body and a light-controlled circuit arranged in the alarm clock. An or-gate circuit and a photoresistor are connected with the light-controlled circuit. The photoresistor leads the circuit of the complete light-controlled alarm clock to conduct under the irradiation of external lights, electric current flows through the circuit, and an electric bell vibrates and makes a sound under the current-controlled action. Conversely, the alarm clock cannot alarm in the dark. The light-controlled alarm clock has the advantages of simple structure, light control, resource conservation, convenient use and strong practicability, and is beneficial for environmental protection.
Description
Technical field
The utility model relates to alarm clock, particularly light-operated alarm clock.
Background technology
Alarm clock is an instrument relatively commonly used during people live, and no matter is that study or work usually will be used alarm clock, it can be regularly and reminds people go to school on time or go to work.Now also of all kinds to the improvement of alarm clock, quartz alarm clock, multi-functional alarm clock, electronic alarm clock, mechanical alarm clock or the like are arranged, as the patent No. is the improved electronic alarm clock of 02294428.1 invention, it comprise be integrated with timing, demonstration, make a noise ring be provided with, making a noise to ring excites, makes a noise and ring the central control unit of control function, the battery of power supply is provided for central control unit, by the alarm clock responding device that the loudspeaker and the switch of mutual series connection setting are formed, described electronic alarm clock can also have the function of the illumination of turning on light when the alarm time of setting send ring tone.But described improved electronic alarm clock still relies on the conventional batteries energy, and the very important person regularly seems not too convenient for going, and forgets easily regularly.
The utility model content
Technical problem to be solved in the utility model is, a kind of light-operated alarm clock is provided, and utilizes light to control alarm clock, and is easy to use.
In order to address the above problem the technical solution of the utility model is such:
Light-operated alarm clock comprises an alarm clock and is arranged on the interior light-operated circuit of alarm clock that the quarter-bell of alarm clock is connected with light-operated circuit.
Be provided with a photoresistance in the described light-operated circuit, photoresistance can make the entire circuit conducting under the irradiation of light, and alarm clock sounds, and removes the off switch alarm clock that just breaks by the people then; When not having light, the circuit of alarm clock is in off-state.
Principle: when light brightened, it is big that the resistance of R becomes, and voltage nearly all is added on the R, and the electromotive force that A is ordered is 6V, and B point electromotive force is about 0V, and through an OR circuit, electric bell is sounded vibration.
The beneficial effects of the utility model are, utilize light to control alarm clock, regularly remind, need not be often regularly, and it only just can sound after daybreak, and is convenient and reliable.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the circuit theory diagrams of the light-operated alarm clock of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of light-operated alarm clock comprises the alarm clock body and is arranged on the interior light-operated circuit of alarm clock that the quarter-bell of alarm clock is connected with light-operated circuit.
Photoresistance R makes the overall optical control circuit just be able to conducting under the irradiation of light, and quarter-bell just sends the tinkle of bells until removed the off switch alarm clock that just breaks by the people under the effect of Current Control then, has played the effect of quarter-bell; Described photoresistance R is that existing technology can arrive realization, and a light-operated circuit is set then.
Principle: when light brightened, it is big that the resistance of photoresistance R becomes, and voltage nearly all is added on the photosensitive R, and the electromotive force that A is ordered is 6V, and B point electromotive force is about 0V, and through an AB OR circuit, electric bell is sounded vibration.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1, light-operated alarm clock comprises an alarm clock, it is characterized in that, is provided with the light-operated circuit that links to each other with quarter-bell in the described alarm clock, is connected with a photoresistance in the described light-operated circuit.
