The internal light loop of the utility model displays changed colors, and the minute and the second light loops are changed in sequence in a period. The utility model has the advantages of innervation of the appearance and accurate timing.

Description

Light spot timer

The utility model belongs to a kind of electronic clock, and specifically a kind of light-emitting component by the control of time base shift register group is formed the timer of time indication dial plate.

Present timer majority is that pointer-type is with digital, pointer-type timer advantage is that sense directly perceived is strong, relatively more traditional, its shortcoming is to show and the reading out of true, and digital timer is to develop a big class timer on the advances in electronic technology basis, its advantage is that timing shows accurately, but a little less than the sense directly perceived, and along with the change of social consumption custom, for timer, it is decorated people and artistic effect has higher pursuit, thereby digital timer more can not adapt to this needs.

The utility model is based on the digital and electronic sequential circuit, a kind of arrangement and the variation of state light spot timer of showing the time with luminous point disclosed, its advantage is that sense directly perceived is strong, show accurately, the environment dark at light can show the time clearly, card has innervation, is rich in sight and decorative effect.

The utility model is made up of dial plate and one group of electronic clock logical circuit, described circuit comprises that one group is exported 1 respectively, the time base circuit of 100HZ clock signal, one group respectively on time, minute, second is the ring shift holding circuit of cycle period, one group of disappear equalizing network and time adjusting circuit, it is characterized in that described dial plate comprises at least by luminescent diode component is arranged in three concentric rings of light, the ring of light when ring of light is respectively from the inside to the outside, divide the ring of light, second ring of light, when the adjacent light-emitting component of each ring of light is represented respectively, chronomere of minute, second.Form each corresponding register output terminal that each light-emitting component of respectively indicating the ring of light is connected to the time shift registers group in proper order, the semiconductor light-emitting elements of the indication ring of light is the variable color light emitting diode during composition.

Below with reference to embodiment description of drawings technical scheme details:

Fig. 1 is the time base circuit figure of the utility model circuit part

Fig. 2 is the utility model other parts circuit diagram except that Fig. 1

Fig. 3 is the floor plan of card.

Time base circuit (as shown in Figure 1) at first produces high stable 1MHZ clock signal by the 1MHZ crystal oscillator, clock signal through six 10 frequency dividing circuit 74LS390 generation 1HZ, the clock signal that simultaneously picks out 100HZ at the 4th 74LS390 output terminal is used to the equalizing network that disappears, circulation holding circuit group, branch circulation holding circuit group, second circulation holding circuit group when the ring shift holding circuit is divided into, each holding circuit group all is to be made of d type flip flop 74LS175.Second indicating circuit is totally six ten d type flip flops, and label is S ₁-S ₆₀, divide indicating circuit to have 60 d type flip flops equally, label is M ₁-M ₆₀, by that analogy, the time indicating circuit 12 d type flip flops are arranged, label is H ₁-H ₁₂, it is identical that each cycling circuit is formed with principle of work, only with second cycling circuit be that example illustrates the course of work.After powering on, S ₁-S ₆₀, M ₁-M ₆₀, H ₁-H ₆₀Q end be all low level, corresponding pilot lamp does not work, because S ₁Input end be connected on S ₆₀Q, when the 1HZ clock of doing arrives, S ₁-S ₆₀Trigger all move, make S ₁-S ₆₀Q end when 60 time clock of first time clock to the arrive, become high level successively, all be high level during by 60 seconds, the light emitting diode that is connected in the d type flip flop output terminal of correspondence brightens.So S ₆₀Q as the common clock of minute cyclic shift circuits, realize with 60 seconds i.e. carries of one minute.And the Q of M60 holds cyclic shift circuits clock signal when being in the branch indicating circuit, realizes 60 minutes i.e. carries of 1 hour, and the equalizing network that disappears is made up of the ternary control gates of three 74LS125, and the input end unification meets 100H _zThe steady pulse that disappears, control end meets S respectively ₆₀, M ₆₀, H ₁₂Q end, output connect respectively second, branch, the time cyclic shift circuits clock end.Time adjusting circuit is made up of 555 integrated circuit, realizes setting, resistance R to hour, minute respectively ₁₄₇, R ₁₄₅, R ₁₄₆And capacitor C ₁Be the circuit peripheral cell, output terminal by keyboard button and parallel circuit, the time circuit clock signal join.

Dial plate is the utility model major technique feature place, three concentric rings of light that are arranged in by semiconductor light-emitting elements are arranged on the dial plate, second ring with divide ring each forms by 60 luminous points, the time ring forms by 12 luminous points, the time 12 luminous points encircling are employing variable color light emitting diodes.

After powering on, second, ring and branch ring were lighted at the luminotron and the round dot place luminotron in this moment of indication, other luminotron does not work and encircle upward, and time ring at this luminotron constantly of indication between the initial point luminotron being a kind of color, and all the other pipes are another kind of color, the photoelectricity state of above-mentioned luminotron changes in time and in proper order, dial plate produces figure and change color is rich dynamic, and especially at the dark place, it is more clear that clock shows, timing is directly perceived, accuracy of reading, the dial plate design is easy to generate the Handicraft decorative effect, more multiple design can be arranged for large-scale clock and watch especially, the timer cost of manufacture is low, and element failure rate is little.
