Description

Light clock

Technical field

The utility model relates to the timing field, is specifically related to a kind of light clock with the electroluminescence device displaying time.

Background technology

Existing clock and watch comprise that mainly the parts such as clock body, clock dial, movement and pointer form, and clock dial is provided with time scale, drive pointer by movement and carry out persond eixis.

Just in order to overcome existing clock and watch need to can be checked by other lamp sources the time when night or light are darker problem, the light clock of electroluminescence device displaying time occurred using.For example the patent No. is the utility model patent of 95236624.X, a kind of light clock is disclosed, it includes clock body, clock dial, power supply, be provided with electronic circuit board in the clock body, be provided with on the clock dial show second, minute, the time electroluminescence device, be provided with on the wiring board to second, minute, the time electroluminescence device control circuit controlled.

Above-mentioned light clock is to come displaying time with the quantity of luminous electroluminescence device, although when night, can come the metering time by the amount of luminescence of calculating electroluminescence device, but also brought very large puzzlement to the user simultaneously, quantity when the user need to count first electroluminescence device and represents, count again quantity that electroluminescence device represents minute and second quantity, because divide with second 60 units are arranged all, so check the whole time, need to spend many time.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of light clock is provided, and adds the display module of direct displaying time numerical value on the basis of existing light clock at clock dial, to solve the problem described in the background technology.

In order to solve the problems of the technologies described above, a kind of light clock of the utility model comprises clock body, clock dial, power supply and is located at PCB circuit board in the clock body, is provided with when showing on the described clock dial, the led chip of minute, second and the display module of displaying time numerical value.

Described PCB circuit board is provided with when showing, the led chip of minute, second drives the control circuit of control, the display module of displaying time numerical value is driven the display circuit of demonstration, and be the power circuit that control circuit and display circuit are powered; Described control circuit when showing, the led chip of minute, second is electrically connected, described display circuit is electrically connected with the display module of displaying time numerical value, described power circuit, control circuit and display circuit are electrically connected in twos.Power circuit is control circuit, display circuit power supply, when control circuit drive to show, when the led chip of minute, second shows respectively, minute, second, simultaneously above-mentioned time value is transferred to display circuit, display circuit control display module shows above-mentioned time value.

Further, described display module is comprised of several LED surface-mount digital tubes.The LED surface-mount digital tube is packaged together by a plurality of light emitting diodes (LED) and forms the device of " 8 " font, and lead-in wire has connected in inside to be finished, and only need draw their each stroke, public electrode.The color of the LED of its use has many middle selections, such as red, green, blue, Huang etc.Therefore this display module has shown the numerical value time on the basis attractive in appearance that keeps former clock dial, brings advantage to the user.

The utility model adopts said structure, has following advantage:

1. add the display module of direct displaying time numerical value at clock dial, calculative puzzlement when the release user checks the time at every turn makes the user obtain fast, easily time numerical value;

2. the electroluminescence device of displaying time all adopts led chip to realize on the clock dial of the present utility model, and the internal characteristics of LED has determined that it has lot of advantages, such as: volume is little, power consumption is low, long service life, high brightness, low in calories, environmental protection and sturdy and durable etc., therefore light clock of the present utility model has lot of advantages, such as attractive in appearance, life-span length, energy-conserving and environment-protective etc.;

3. the led chip on the clock dial of light clock of the present utility model arrange to adopt aesthetics design, and overall appearance is generous, and has transformed traditional display format that pointer adds scale, and is novel, practical, attractive in appearance.

Description of drawings

Fig. 1 is the synoptic diagram of embodiment of the present utility model.

Embodiment

Now with embodiment the utility model is further specified by reference to the accompanying drawings.

As specific embodiment of the utility model, as shown in Figure 1, a kind of light clock, comprise clock body 1, clock dial 2, power supply (showing on the figure) and be located at PCB circuit board (showing on the figure) in the clock body 1, be provided with when showing on the described clock dial 2, the led chip 21 of minute, second and the display module 22 of displaying time numerical value.

Described PCB circuit board be provided with to the led chip 21 that shows Hour Minute Second drive control control circuit, the display module 22 of displaying time numerical value is driven the display circuit of demonstration and is the power circuit of control circuit and display circuit power supply.Described control circuit when showing, the led chip 21 of minute, second is electrically connected, described display circuit is electrically connected with the display module 22 of displaying time numerical value, described power circuit, control circuit, display circuit are electrically connected in twos.Wherein, power circuit is control circuit, display circuit power supply, when control circuit drive to show, when the led chip 21 of minute, second shows respectively, minute, second, simultaneously above-mentioned time value is transferred to display circuit, display circuit control display module 22 shows above-mentioned time value.

The position that described led chip 21 is located on the clock dial 2 is not determined, but User demand or Angel of Aesthetic come specific design.Led chip 21 in the present embodiment is evenly arranged into three concentric circless, and the circle of inner lane is the upper 12 LEDs chips that distribute evenly, represents 12 division of day and night, are evenly distributed with 60 LEDs chips on the circle of mesosphere and outer ring, represent 60 seconds/divide.For example, when displaying time is 10:27:35, there are 10 LEDs chips bright on the inner lane, represent at 10 o'clock, have 27 LEDs chips bright on the mesosphere, represent 27 minutes, have 35 LEDs chips bright on the outmost turns, represent 35 seconds.

Described display module 22 is comprised of several LED surface-mount digital tubes.The LED surface-mount digital tube is packaged together by a plurality of light emitting diodes (LED) and forms the device of " 8 " font, and lead-in wire has connected in inside to be finished, and only need draw their each stroke, public electrode.The color of the LED of its use has many middle selections, such as red, green, blue, Huang etc.Therefore this display module has shown the numerical value time on the basis attractive in appearance that keeps former clock dial, brings advantage to the user.As shown in the figure, the display module 22 in the present embodiment has 6 LED surface-mount digital tubes, wherein two when showing, two show minute, two show second.Therefore, the user can see the time intuitively, and does not need through counting light led chip on 3 concentric circless.
