Abstract

The utility model discloses a light emitting diode (LED) clock. LED indicating lamps are evenly distributed on the LED clock. The number of the LED indicating lamps is 60. The LED indicating lamps are composed of 12 big lamps and 48 small lamps, wherein the big lamps are arranged on hour scales, and the small lamps are arranged on minute and second scales. The LED indicating lamps and a control circuit are connected to form a matrix with a drive function. The control circuit comprises a single chip microcomputer (SCM) and a clock chip. The clock chip and the LED matrix are respectively connected with an input/output (I/O) port of the SCM. The type of the SCM is STC125LE08S2, and the type of the clock chip is DS1302. The LED clock has no minute needles, hour needles and second needles, is noiseless in operation, achieves illuming or turning off according to a standard time through the SCM and a peripheral circuit, and is simple in structure, and low in cost.

Description

A kind of LED clock

Technical field

The utility model relates to a kind of LED clock, belongs to the technical field with the device of optical mode instruction time.

Background technology

The clock and watch of prior art adopt hour hands, minute hand and second hand instruction time mostly, and operation is got up and can ticktack be rung, and the clock and watch that replace hour hands, minute hand and second hand with the LED lamp is also arranged on the market, but have complex structure, cost high-technology defective.

The utility model content

The purpose of the utility model is to provide a kind of operation get up noiseless and LED clock simple in structure, that cost is low, solves the shortcoming that prior art exists.

The utility model adopts following technical scheme to realize:

A kind of LED clock is evenly distributed with LED light on this LED clock, and said LED light has 60; Form by 12 headlights and 48 lampets, wherein headlight be positioned at clock the time scale on, lampet is positioned on branch, second scale; It is characterized in that; LED light link to each other with control circuit form one have driving force matrix, said control circuit comprises single-chip microcomputer and clock chip, said clock chip and LED matrix are connected to the I/O mouth of single-chip microcomputer.

Further, the model of said single-chip microcomputer is STC125LE08S2, and the model of said clock chip is DS1302.

The LED clock that the utility model possesses does not have minute hand, hour hands and second hand, the operation noiseless of getting up, and can realize lighting or extinguishing according to the standard time through single-chip microcomputer and peripheral circuit thereof, simple in structure, with low cost.

Fig. 2 is the circuit block diagram of the utility model LED clock.

Embodiment

Through facing the description of embodiment down; To help public understanding the utility model more; But can't be regarded as restriction by the concrete embodiment that the applicant is given to the utility model technical scheme, any definition to parts or technical characterictic change and/or to one-piece construction do form but not the conversion of essence all should be regarded as the protection domain that technical scheme limited of the utility model.

The LED clock of the utility model as depicted in figs. 1 and 2 is evenly distributed with LED light on this LED clock, and said LED light has 60; Form by 12 headlights 1 and 48 lampets 2; Wherein headlight 1 be positioned at clock the time scale on, lampet 2 is positioned on branch, second scale, LED light link to each other with control circuit form one have driving force matrix; Said control circuit comprises single-chip microcomputer and clock chip; Said time module and LED matrix are connected to the I/O mouth of single-chip microcomputer, and the model of said single-chip microcomputer is STC125LE08S2, and the model of said clock chip is DS1302.When clock chip DS1302 produces, branch, second integrated circuit modules, be composed of program in the single-chip microcomputer STC125LE08S2, in real time the data of acquisition clock chip DS1302; Carrying out scan control shows 60 LED light location come; T1 is a triode amplifier among Fig. 2, and LS1 is the loudspeaker that give the correct time, lampet be positioned at branch, second scale on; The time lamp normal bright and per hour jump a time modulation position; The branch lamp is in the flicker shape and kept 60 seconds before jumping into next branch, a second lamp per second is jumped once, reaches demonstration time and the purpose of giving the correct time.

Certainly; The utility model can also have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
