Abstract
The utility model discloses an ice strip lamps control circuit in which the power supply of the control circuit is a direct current power supply which is connected with the power pins of the micro processor unit MCU after filtration, the input pins of the micro processor chip MCU are connected with the regulate switches of the ice strip lamps by an adjustable resistance VR1, and the output of signal from the output pins of the micro processor unit MCU is amplified to be sent to the lamps in the strip. The control circuit provided in the utility model adopts the direct current power supply to avoid flickering caused by voltage fluctuation, the differential input port of the micro processor unit MCU of the control circuit is connected with the adjustable resistance which is controlled by the regulate switch to facilitate the regulation of the flashing of the strip lamps to change the dynamic effect. The utility model is low in power consumption of the control circuit and with good safety.
Description
Technical field
The utility model relates to the decorative lighting technical field, is specifically related to a kind of control circuit of decorative chain of mutual series connection.
Background technology
Decorate with Color lamp string as a kind of red-letter day celebrating decorative lighting articles for use more and more be subjected to people's favor.In recent years, in order to increase the celebrating atmosphere of lamp string, people often furnish into various moulding with the lamp string, for example broken line type, circle, netted moulding or the like.The also installation and control circuit in the lamp string that has realizes that the brightness of different bulbs in the lamp string is switched, and increases dynamic effect.
At present the LED Color lamp string that uses generally adopts alternating current directly to connect with the lamp polyphone, thus the situation that causes the LED bulb often to occur glimmering because of alternating voltage, alternating current can make the LED bulb produce reverse voltage simultaneously, thus the reduction bulb life.
The disclosed lamp band that can multiple variation of Chinese patent CN03211402.8 patent " single line is controlled the lamp band of multiple variation ", be provided with some control circuits and luminous element in its plastic outer layer, some control circuits are controlled by a control line, luminous element and control circuit are formed a luminescence unit, the lamp band is made up of a plurality of luminescence units, a plurality of luminescence units are connected by three leads, two power lines wherein, a control line.Can realize that chasing of multichannel lamp flash, but this structure relative complex makes the energy consumption height of whole lamp band, also increased production cost, practicality is not strong.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, and is low in energy consumption and can realize the control circuit structure that the lamp string is dynamically beated.
The utility model is achieved through the following technical solutions:
Design a kind of ice bar lamp control circuit, the power supply of control circuit adopts DC power supply, power supply is connected to earlier the supply pin of little process chip MCU after resistance capacitance filtering, the input pin of little process chip MCU connects with the regulation and control button of ice bar lamp string by adjustable resistance VR1, and the signal of the output pin output of little process chip MCU connects with the bulb of lamp string after amplifying.
The utility model compared with prior art has following remarkable advantage:
Control circuit provided by the utility model, adopt DC power supply to avoid the situation that occurs glimmering because of voltage fluctuation, the differential input terminal of the little process chip MCU of control circuit connects the adjustable resistance of regulation and control button control, conveniently regulates the glittering of lamp string, changes its dynamic effect.The utility model control circuit low in energy consumption, safe.
Description of drawings
Fig. 1 is a circuit theory schematic diagram of the present utility model;
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
With reference to shown in Figure 1, a kind of ice bar lamp control circuit, the power supply that includes bulb and be connected with bulb, the power supply of control circuit adopt DC power supply VCC power supply, draw one road power supply signal and directly are connected to bulb L1, working power are provided for bulb L1.Another road power supply is attached to earlier the supply pin 1 of little process chip MCU after resistance R 1, R2 current limliting dividing potential drop, working power is provided for little process chip MCU.The signal that triggering signal end X sends is by the be added to supply pin of little process chip MCU of capacitor C 2, C3.
Connect adjustable resistance VR1 between the input pin 2 and 3 of little process chip MCU, the regulation and control button of adjustable resistance VR1 and ice bar lamp string is joining, the signal of output pin 5 outputs of little process chip MCU drives by controllable silicon Q7 and lights bulb L2 after triode Q3 amplifies.
During work, bulb L1 electrified light emitting is in normal bright state, microprocessor chip MCU supply pin is connected simultaneously, adjustable resistance VR1 is in certain position, when wanting to change the glittering state of lamp string, regulate the button that connects with adjustable resistance VR1, change input value between little process chip MCU differential input terminal 2,3, little process chip received signal is handled the signal after the back changes from output 5 outputs, and by being transported to controllable silicon Q7 after the triode Q3 amplification, controllable silicon Q7 conducting work, bulb L2 lights, and not conducting of controllable silicon bulb L2 goes out.Bulb L1 Chang Liang, bulb L2 is glittering, thereby forms dynamic effect.
Claims (2)
1, a kind of ice bar lamp control circuit, the power supply that includes bulb and be connected with bulb, it is characterized in that: also be provided with little process chip MCU between described power supply and the bulb, the regulation and control button of the input pin of little process chip MCU and ice bar lamp string links, and the signal of the output pin output of little process chip MCU connects with the bulb of lamp string after amplifying.
