Description

It is a kind of to gather the quartz clock that automatic photoinduction dims and LED display second points are run

Technical field

Quartz clock field is the utility model is related to, more particularly to a kind of automatic photoinduction light modulation of set and LED show the second The quartz clock that point is run.

Background technology

Quartz clock is very common in daily life, the electronic clock shown compared to new LCD, and quartz clock retains The rotating mechanical aesthetic feeling of pointer, still there is a good occupation rate of market.But quartzy hand of a clock operation can not jump a second drive Minute hand, minute hand drive this rule of hour hands, and almost all of quartz analog clock can only do text in appearance in quartz clock Chapter, such as replace shell or replace clock face or replace clock hand, for the no more novel processing side of mode when walking of quartz clock Formula.For this problem, with reference to current existing scientific and technological level, in the effect of running of second, generation, are made by the flicker of LED light For the effect of the display second of second hand, minute hand and hour hands can be thus left behind, makes product renewing grain husk, more fashion.

Second effect of running shown usually using the form of running lamp, i.e., the effect that 60 LED lamps are shown in turn. Analyzed from technical standpoint that is, thering is a LED lamp is lasting to light on quartz clock always.This can bring three problems, and one It is the superelevation power consumption problem that LED light is persistently lighted, can strongly reduces the service life of battery；Second, LED light is persistently lighted pair The fatigue problem of vision, can make user sense of discomfort occur when observing whole quartz clock；Third, 60 LED lamps are to resource and cost Influence.For these problems, with reference to current existing scientific and technological level, dodged by improving the flash pattern of LED for every five seconds for example A lamp is sparkled, so as to reach the effect that LED light runs the second.

The mode of traditional lightening LED lamp, is as the signal lighted directly using a lasting level to LED light.But Lasting lightening LED lamp has substantial amounts of electric energy loss, this is this usually only using conventional dry cell for quartz clock, and does not have Other useful power supplys are a very big tests as the product of support.It should ensure the brightness of lighting of LED light, ensure again The service life of dry cell.It is special by using control IC outputs with reference to current existing scientific and technological level for this problem Different signal, this signal are high-frequency Sasser, are known as PWM outputs, and this waveform can reach significant power saving effect, again LED can be made to send the brightness for meeting display effect.

Automatic photoinduction is applied on the public system such as street lamp or corridor lamp, in fact, part hommization Family with greater need for coordinate photoinduction technology.Such as ambient brightness than relatively low, will seem and pierce very much when using TV or computer Eye；And when using mobile phone, the brightness of screen can change with the change of ambient brightness, be more suitable for brightness.For This problem, with reference to current existing scientific and technological level, by using the design on photosensitive sensor and hardware circuit, so that it may To realize that quartz clock carries night dimming function so that LED light seems not dazzling at night, and can be shown in the daytime High brightness.
