Abstract
The utility model discloses a kind of LED string control loop of automobile meeting pedal, comprise power module, IC control chip and lamp string circuit, described lamp string circuit comprises the LED branch road be connected in parallel more than two, described LED branch road is provided with LED, and the triode of to connect with LED, the base stage of described triode connects the output of IC control chip, and the emitter of triode connects LED.LED string control loop of the present utility model is all provided with the triode as control switch on each group LED branch road, the base stage of the output connecting triode of IC control chip, the state that can control separately each group LED branch road changes, and do not affect other branch road, this design makes the state of single led lamp string more change, thus more lighting effects can be combined into, when being applied on automobile meeting pedal, there is better decorative effect.
Description
Technical field
The utility model relates to control circuit, particularly relates to the LED string control loop of automobile meeting pedal.
Background technology
LED has low in energy consumption, and the life-span is long, and volume is little, light utilization efficiency advantages of higher, and the advantages such as energy-conserving and environment-protective are called as forth generation green illumination light source.LED operationally requires constant current hold, and therefore, LED is generally configured with constant current driving device and drives.
LED string generally comprises the LED (group) of multiple parallel connection and/or series connection, and LED string is mainly used on decoration, as the decorative lamp etc. on the decorative chain of party, automobile.LED on existing automobile meeting pedal is ganged up lamp string forefront of being everlasting and is provided with an IC control chip, is provided with control assembly in IC control chip, and the LED (group) that can control lamp string opens or closes, and produces the effect of flicker thus.But this LED is ganged up and often can only be carried out open and close or flicker three kinds of states controls, changes little, when needing to produce complicated change, need multiple lamp string to coordinate and just can reach, circuit is complicated, and need to increase Assembly interface on automobile meeting pedal, use inconvenience.
Utility model content
Therefore, the utility model is for the technical problem of existing LED string decorative effect deficiency, and object is the LED string control loop providing a kind of automobile meeting pedal.
The technical scheme that the utility model adopts is:
The LED string control loop of automobile meeting pedal, comprise power module, IC control chip and lamp string circuit, described lamp string circuit comprises the LED branch road be connected in parallel more than two, described LED branch road is provided with LED, and the triode of to connect with LED, the base stage of described triode connects the output of IC control chip, and the emitter of triode connects LED.
As the further improvement to technique scheme, described LED branch road is provided with a LED.
As the further improvement to technique scheme, described LED branch road is provided with multiple LED be connected in series.
As the further improvement to technique scheme, described LED branch road is provided with divider resistance.
As the further improvement to technique scheme, described triode is NPN pipe.
As the further improvement to technique scheme, described IC control chip is provided with multiple control output ends mouth, and each control output end mouth connects one group of LED branch road.
As the further improvement to technique scheme, described IC control chip is SSOP20 packaged chip.
As the further improvement to technique scheme, described power module adopts 7805 stabilized voltage power supply chips.
The beneficial effects of the utility model are:
LED string control loop of the present utility model is all provided with the triode as control switch on each group LED branch road, the base stage of the output connecting triode of IC control chip, the state that can control separately each group LED branch road changes, and do not affect other branch road, this design makes the state of single led lamp string more change, thus more lighting effects can be combined into, when being applied on automobile meeting pedal, there is better decorative effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the circuit diagram of lamp string of the present utility model;
Fig. 2 is the circuit diagram of IC control chip of the present utility model;
