The control part is composed of a singlechip, resistance and a triode, wherein a signal output pin of the singlechip comprises a row control signal output pin and a column control signal output pin, and an internal control program controls the LED bulbs to be on and off. The meteor lamp has the advantages of simple circuitry, low failure rate and low cost.
Description
Affiliated technical field
The utility model relates to the decorative lighting field, particularly a kind of meteor lamp.
Background technology
The meteor lamp has another name called the lamp that drips, and has one bright section successively toward dirty in the inner a lot of bulb in energising back, produces similar meteor or raindrop phenomenon, is used for decorations such as road, trees, eaves more.This product mainly is made up of display part, control section and power supply in the market, and the display part comprises a lot of LED bulb; Control section comprises horizontal drive device and row drive unit, and display part and control section are distributed on the circuit board by the circuit requirement, outside cover layer of transparent plastic tube.Its control section is made up of multiple electronic component and a plurality of chip, the circuit complexity, and cost is higher, because meteor circuit for lamp plate width is narrower, requires each component size of control section necessary little, thereby makes that the production technology difficulty is bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of meteor lamp of simple and easy control circuit.
For achieving the above object, the technical scheme that the utility model adopted is: the meteor lamp, comprise display part and control section, and both are distributed on the circuit board by circuit relationships, and skin is with the transparent plastic cover, and is connected to power supply.The display part is that a matrix is arranged the LED bulb, and the LED bulb can be direct insertion, also can be SMD; Control section is made up of single-chip microcomputer, resistance, triode, the output pin of single-chip microcomputer comprises capable control signal output pin and row control signal output pin, all be connected to resistance and triode in proper order between each output pin and the LED bulb, another pin of triode extremely links to each other with power supply one.The built-in control program of single-chip microcomputer, the signal output of control signal output pin, promptly low level output makes the triode conducting, thereby makes the energising of LED bulb.
Compared with prior art, control section of the present utility model only is made up of single-chip microcomputer, resistance and triode.The signal output pin of single-chip microcomputer has comprised capable signal output pin and column signal output pin, and the built-in control program of single-chip microcomputer is controlled the signal output of each pin, and the driving by resistance and triode is switched on the LED bulb of display part on request again.Its circuit is simple, and fault rate reduces greatly, and cost also reduces.

The specific embodiment
With reference to Fig. 1, among the utility model embodiment, this meteor lamp mainly comprises display part (X) and control section (1, HK and LK). display part (X) is that a matrix is arranged the LED bulb, the LED bulb can be direct insertion, also can be SMD, constitute by 8 row and 16 row, each LED bulb capacitors connection in wherein every row, each LED positive pole in every row is in series. and control section is by single-chip microcomputer (1), resistance (2,3 and 4), triode (5) is formed, be divided into capable control section (HK) and row control section (LK), the row control section is by the capable signal output pin of single-chip microcomputer, two resistance (2,3) and triode (5) constitute, row signal output pin links to each other with resistance (3), resistance (3) links to each other with triode (5) one pins, two other pin of triode (5) links to each other with power cathode (6) with LED bulb negative pole respectively, being provided with a current-limiting resistance (2) between triode (5) pin and the LED bulb. row control section (LK) is similar with row control section (HK), by single-chip microcomputer column signal output pin, resistance (4) and triode (5) constitute, the column signal output pin links to each other with resistance (4), resistance (4) links to each other with triode (5) pin, two other pin of triode (5) links to each other with positive source (7) with the LED bulb is anodal respectively. in the present embodiment, make the 1st LED bulb (L1) shinny, then the 1st capable signal output pin (HJ1) of single-chip microcomputer exported a low level, make triode (5) conducting, thereby LED bulb negative pole and power cathode (6) are conducted; Low level of first column signal output pin (LJ1) output of single-chip microcomputer simultaneously, make triode (5) conducting, the LED bulb is anodal to be conducted with positive source (7) thereby make, like this, just begin shinny after the energising of LED (L1) both positive and negative polarity. according to this principle, the time of single-chip microcomputer capable signal pins of built-in control program control single chip computer and the output of column signal pin, thus it is bright to ending from beginning to control one section LED bulb, and repeat this operation.
Among Fig. 2, display part and control section are distributed on the circuit board by circuit relationships, and wherein the LED bulb of display part is in line on circuit board.
Among Fig. 3, the circuit board outside is with a transparent plastic cover (8), can play waterproof action, and be connected to a 5V constant voltage source (9).
