Однако известньте электронные часы имеют недостаточную контрастность при индикации показаний.However, know the electronic clock has insufficient contrast when displaying readings.

Из звестных наручных часов наиболее близкими по техшгческой сущности к предлагаемым вл ютс электронные часы, содержащие задающий генератор, блок делени частоты, логический блок и блок выделени меток времени, включенные последовательно на выходе задающего генератора, индикатор на светодиодах и блок включени светодиодов 2).Of the known watches, the closest in technical essence to the proposed are electronic watches containing a master oscillator, a frequency dividing unit, a logic unit and a timestamp selection unit, connected in series at the output of the master oscillator, a LED indicator and a LED on unit 2).

Недостаток известных часов - значительный расход тока.The disadvantage of the known hours is a significant current consumption.

Цель изобретени - повысить экономичность часов по расходу тока.The purpose of the invention is to increase the economy of hours in terms of current consumption.

Claims

The clock contains a source Anan I, a master oscillator 2, a dividing unit 3, a logic device 4, -block 5 timestamps, a device 6 for turning on LEDs, a generator and) (pulsator 7, an indicator device 8 for LEDs, an amplitude level controller 9 pulses and photosensitive element 1O. The voltage of the power source 1 through the device enters the block 7, 1-de converts the direct current into the pulse. The pulse frequency is chosen, on the one hand, from the condition of the pulses maximum power gain, power, and Q is different, taking into account the chebwek's eye properties. Powering light emitting diodes with current pulses reduces the power consumption of a clock power supply, In the proposed scheme | amplitude, current pulses do not remain constant, but vary depending on the coverage in which readings of the indicator device are made. / This is a supplementary augment consisting of a photosensitive cell 10 and a pulse amplitude level regulator 9. The current at the output of the photosensitive element 10 is proportional to the Sata stream, which enters its input g, that is, proportional to the illumination in the place where the clock is currently located. This current influences the pulse amplitude level regulator 19, which, acting on the pulse generator 7, changes the amplitude of the pulses depending on the photocurrent value. The proposed scheme allows, depending on the illumination, aa changes which monitors the photosensitive element to change the brightness of the LED indicator, powering its impulse on the current itself of different amplitudes, which leads to an economical power consumption of the electronic wristwatch. a clock containing a master oscillator, a frequency division block, a logic block, and a time stamp selection block connected in series at the output of master clock 1, j indicator The LEDs and the LED turn-on unit, which are designed so that, in order to improve the efficiency of current consumption, they are equipped with a controlled pulse generator, a photosensitive element and an amplitude regulator, the output of the photosensitive element is connected to the input of the amplitude regulator The output of the amplitude controller is connected to the first input of the controlled generator, the output of which is connected to the indicator, and the second input of the controlled generator is connected to the output 1 of the LED turn on unit.
