Abstract
The utility model relates to an induction type luminous watch, wherein, corresponding twelve time points of a watch plate are provided with light emitting diodes; an hour hand, a minute hand and a second hand of the watch are respectively provided with a coil whose both ends are connected with light emitting diodes; the coil induction generates electric voltage driving light emitting diodes by the high-frequency oscillation of a multivibrator which generates electromagnetic field near the other coil. Figures and hands on the watch plate of the luminous watch can emit light at night.
Description
The utility model relates to the induction type Luminous Timekeeper that the numeral of a kind of its pointer and dial plate all can be luminous in the dark, particularly is used to make the digital luminous driving circuit of above-mentioned pointer and dial plate
Most of clock and watch night can not instruction time reading, the numeral that some clock and watch is made dial plate with light emitting diode shows, thus can be at display dial reading at night, but the pointer of clock and watch (hour hands, minute and second hand) is not luminous at night, so time for reading is convenient inadequately; Also the pointer of some clock and watch is coated in the fluorescent material that sends radiomaterial and makes it at noctilucence on the pointer, but there is the shortcoming that radiomaterial is harmful and fluorescent material lost efficacy gradually, under the situation that adopts lead to connect, if use the diode displaying pointer, because the rotation of pointer can make lead twine, therefore simple diode displaying is display dial numeral and pointer both.
The purpose of this utility model is exactly to propose a kind of induction type Luminous Timekeeper of doing the demonstration of dial plate numeral and pointer with light emitting diode for the above-mentioned deficiency that overcomes prior art.Realize above-mentioned purpose like this: the light emitting diode of pointer is not connected with the circuit of the light emitting diode that drives the display dial numeral by lead and changes the lumination of light emitting diode that makes display pointer with the magnetic flux of coil-induced circuit generation into, 12 light emitting diodes of position of sound production in corresponding 12 moment of dial plate, like this, the dial digital of induction type Luminous Timekeeper of the present utility model and pointer can both overcome the above-mentioned deficiency of prior art at noctilucence.
Below describe the utility model in detail referring to accompanying drawing.
Fig. 1 is the electrical schematic diagram that is used to drive the driving circuit of above-mentioned lumination of light emitting diode.
As shown in the figure, the 220V alternating current becomes direct current again after diode D1-D4 full-bridge rectification behind resistance R 1, capacitor C 1 resistance-capacitance depressurization, direct current directly drives 12 serial connection LED 1-LED12 that are placed in corresponding 12 moment positions of dial plate after resistance R 2 current limlitings, make it luminous. Direct current also through resistance R 5 current limliting rear drives by triode BG1, BG2, resistance R 3, R4, the multivibrator that capacitor C 2, C3, C4 and inductance L 1 consist of, the higher-order of oscillation of multivibrator is coil L1's Near set up electromagnetic field, the coil L2-L4(on the clock pointers respectively corresponding to the time, minute, second pointer coil) respond to this electromagnetic field, produce voltage at coil L2-L4 two ends, make the light emitting diode DL2-DL4 that is connected the coil two ends luminous. By the figure finding, this multivibrator is typical circuit structure, between the colelctor electrode that resistance capacitance R3, C3 in parallel and R4, C4 are connected on respectively triode BG1 and the base stage of triode BG2 and between the base stage of the colelctor electrode of BG2 and BG1, one output of the common-emitter of BG1, BG2 and diode full bridge rectifier be connected the electrode of the last diode of 12 light emitting diodes of serial connection and be connected, coil L1 and capacitor C 2 are connected on triode BG1, BG2 colelctor electrode two ends.
For the littler clock and watch of dial plate, for saving the space, the indication of dial plate is not adopted aforesaid light emitting diode and is only used a light emitting diode, lead the light of light emitting diode with the photoconduction transmitting fiber tow, optical fiber is distributed in the position in corresponding 12 moment, light emitting diode is at the dial plate back side, and the light that sends is blocked by dial plate.
In an embodiment of the present utility model, oscillator coil L1 is with the two-wire of line footpath φ 0.25 and in the mould of 8 millimeters * 2 millimeters of φ, and the number of turns is the 30-40 circle, and the fixing back demoulding of perfusion coagulating agent gets final product, and the inductance value of the coil that so makes is about 370 microhenrys.Three pointer coils are decided according to the size of clock and watch table column diameter, but these three coils are close as far as possible, coil are annotated the centre at the indicator jack when making indicator.
Claims (1)
1, a kind of induction type Luminous Timekeeper, it is characterized in that light emitting diode LBD1-LBD12 being set in the position in corresponding 12 moment of dial plate, above-mentioned diode is luminous by driven, the voltage of driven for emitting lights diode also drives a multivibrator, the higher-order of oscillation of multivibrator drives and is connected on the triode BG1 in the above-mentioned multivibrator, the coil L1 at BG2 collector two ends, clock and watch the time, the minute, second pin is provided with the coil L2-L4 that two ends are connected with light emitting diode DL2-DL4, the electromagnetic field of coil L2-L4 inductive coil L1.
