Abstract

The utility model relates to a civil electronic quartz clock, which comprises a clock body and a clock plate. The quartz clock is characterized in that LEDs are uniformly distributed at the edge part of the clock plate; a light emitting circuit is arranged in the clock body; the circuit is a closed loop formed in a mode that the parallel LEDs are connected in series with a capacitor, a resistor and alternating current. The quartz clock has the utility model of simple structure, low cost and low power consumption and has the advantages that the quartz clock emits soft green light rays at night; the quartz clock can be observed with time display as well as can provide illumination, and can also not influence people's sleep.

Description

Quartz clock

The utility model belongs to civil electronic crystal clock technical field, particularly a kind of crystal clock that can be when showing night.

At present, the crystal clock kind of selling on China's production and the market is more, and can be divided into following several substantially: a kind of is common electronic quartz clock; Another kind is can be with the crystal clock of getting ready and music is given the correct time (comprising light-operated).This crystal clock especially night musical sound seem very big, also bigger to sleeper influence; Having a kind of again is to have the crystal clock of going through Presentation Function even-numbered days; Also having a kind of in addition is the crystal clock that has annular daylight lamp, and this crystal clock power consumption is big, and night, light seemed dazzling especially, and it is sleeping to influence people, and cost is higher.Up to the present, lower and crystal clock function when having night illumination and showing of a kind of price does not also appear on the market.

It is a kind of cheap that the purpose of this utility model is to provide, and has the crystal clock that night illumination shows time function.

The purpose of this utility model is achieved in that it includes clock body, clock dial etc., edge at clock dial is evenly distributed with 6～24 light emitting diodes, one illuminating circuit that makes lumination of light emitting diode is arranged in the clock body, and this illuminating circuit is meant that light emitting diode in parallel connect with an electric capacity, resistance and the closed-loop path of alternating current composition.As long as circuit communication, can send at night a kind ofly both can provide illumination the demonstration time, did not influence the light that people sleep again during use.

The utility model can be on the basis that does not change original crystal clock function, and changing a little to increase functions of use, so cost is lower, and this structure adopts ac power supply method, and power consumption is extremely low.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

Referring to Fig. 1, a kind of concrete structure of the present utility model is: it comprises existing crystal clock clock body 1, clock dial 2, on 12 time figure relative positions of clock dial 2, be evenly distributed with 12 light emitting diodes 3,12 light emitting diodes are in parallel to connect with an electric capacity (C=02 μ F), resistance (R=120 Ω) again to be connected in alternating current and to form a closed-loop path (Fig. 2).In use, continuous 24 hours power consumption of 12 light emitting diodes is minimum, and (ammeter is almost motionless) sends a kind of soft green light at night, both can see time showing in night, also can provide illumination, do not influence people's sleep again.

Claims

1, a kind of civil electronic crystal clock, it includes clock body, clock dial, it is characterized in that: the edge at clock dial is evenly distributed with 6～24 light emitting diodes, and an illuminating circuit that makes lumination of light emitting diode is arranged in the clock body.

2, civil electronic crystal clock according to claim 1 is characterized in that: illuminating circuit is meant the closed-loop path that light emitting diode in parallel is connected with an electric capacity, resistance and alternating current is formed.
