Abstract
The utility model relates to a controller, in particular to an LED switch controller, which comprises a microphone pickup circuit, an amplifier circuit, a comparison delay circuit and an LED lamp driving circuit. Output signals of the microphone pickup circuit are sent to the LED lamp drive circuit through the amplifier circuit and the comparison delay circuit sequentially. Since the microphone pickup circuit, the amplifier circuit and the comparison delay circuit which are low-cost are utilized, the LED switch controller can control to swith on an LED lamp automatically when people walk in a dark corridor and make sounds or vibration during walking, and then control to switch off the LED lamp automatically after delaying. Accordingly, the LED switch controller is energy-saving, economical and practical and has effect of controlling lighting automatically.
Description
Technical field
The utility model relates to a kind of controller, and what be specifically related to is a kind of LED on-off controller.
Background technology
In public; Use on-off ratio wired or touch delay switch control lamp more common like corridor, less but the audio-switch on the existing market has opening or closing of vibration control LED lamp simultaneously, and its function singleness; Control is unstable; Expense is high, often causes waste of electric energy, therefore is necessary prior art is further improved.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of LED on-off controller is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of LED on-off controller; Comprise microphone pickup circuit, amplifying circuit, comparison delay circuit and LED lamp drive circuit, the output signal of said microphone pickup circuit is sent to the LED lamp drive circuit through amplifying circuit, comparison delay circuit successively.
Said microphone pickup circuit comprises resistance R 1, the capacitor C1 that microphone MIC and output thereof connect, resistance R 1 shunt capacitor C1.
Said amplifying circuit comprises the amplifier that transistor T 1-T6 constitutes.
Said relatively delay circuit adopts NE555 time-base circuit IC1.
Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: this controller adopts microphone pickup circuit, amplifier circuit, comparison circuit etc. cheaply, when people go to dark corridor, sounds or during the walking vibration; This controller can be opened automatically; After time-delay, close the LED lamp automatically, reach automatic control illumination, energy-conservation, economic, practical effect.
Description of drawings
Fig. 1 is the block diagram of the utility model;
Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2; A kind of LED on-off controller of the utility model; Comprise microphone pickup circuit 1, amplifying circuit 2, compare delay circuit 3 and LED lamp drive circuit 4; The output signal of said microphone pickup circuit 1 is sent to LED lamp drive circuit 4 through amplifying circuit 2, comparison delay circuit 3 successively, and said microphone pickup circuit 1 comprises resistance R 1, the capacitor C1 that microphone MIC and output thereof connect, resistance R 1 shunt capacitor C1; Amplifying circuit 2 comprises the amplifier that transistor T 1-T6 constitutes, and relatively delay circuit 3 adopts NE555 time-base circuit IC1.During at last corridor, when microphone MIC detects sound or vibration, just produce a signal of telecommunication as the people; This faint signal of telecommunication becomes direct voltage after transistor T 1～T6 amplification and rectification, voice signal the 4th pin at NE555 time-base circuit IC1 after changing generates the 12V direct voltage, makes the 3rd pin output the becoming high potential of NE555 time-base circuit IC1; Through resistance R 19 current limlitings; Make triode T7 conducting, relay J 1 adhesive, the closed LED mains lighting supply of connecting of its contact J1-1.When corridor nobody walks about; When microphone MIC also just detects less than walking sound or vibration, NE555 time-base circuit IC1 the 4th pin keep electronegative potential because of resistance R 13 ground connection, the 3rd pin output the becoming electronegative potential of NE555 time-base circuit IC1; Triode T7 is in cut-off state; Its contact J1 discharges, and the LED lamp is in and extinguishes state, realizes economize on electricity, convenient, practical, economic dispatch effect.
An above-described preferred embodiment that is merely the utility model can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
