The specific embodiment
Be described in further detail below in conjunction with the circuit and the circuit theory of accompanying drawing intelligent double-brightness impression LED lamp provided by the present invention.
As shown in Figure 2, be the circuit box schematic diagram of the double-brightness impression LED lamp by the control of the infrared and natural daylight of human body provided by the present invention.The circuit that constitutes this intelligent double-brightness impression LED lamp comprises: the light sensing circuit that is made of light sensing element 11 and the photosignal circuit 12 that is attached thereto, the infrared sensing circuit and the delay switch circuit 8 that are made of human-body infrared sensing element 9 and the infrared amplification circuit of electrical signal 10 that is attached thereto connect and compose state selecting circuit respectively with ternary input with door 5 respectively; Should connect and compose the electromagnetic relay control circuit with the trigger end of the output of door and the trigger switch 6 of control electromagnetic relay coil 13; The normal battle 17 of this electromagnetic relay and normally closed point 14 constitute the circuit of lighting respectively with auxilliary light-emitting component 15 and main light emission element 16, delay switch circuit 8 connects and composes the delay circuit of controlling main light emission element 16 with the 3rd input of above-mentioned three-state and door.
The operation principle of the circuit of above-mentioned double-brightness impression LED lamp by the control of the infrared and natural daylight of human body is:
---during daytime, send the photoinduction signal by light sensing element 11 and make low level of photosignal circuit 12 outputs, no matter have this moment unmanned by the stair corridor of this light fixture has been installed, be no matter infrared sensing circuit produces high level or low level, its ternary output with door is low level, this low level then can not trigger trigger switch 6 conductings, promptly constitutes the state that secondary light source that the LED lamp of the minimum power of floodlight circuit constitutes is in Chang Liang;
---at night, send the photoinduction signal by light sensitive component 11 and make high level of photosignal circuit 12 outputs, this moment as the people when the stair corridor of this light fixture has been installed, infrared sensing circuit then produces high level, delay circuit is set high level always, this moment, its ternary output with door then became high level, this high level triggers trigger switch 6 conductings, its normally closed point disconnects the normal closure of making war, the secondary light source that is made of low power LED that promptly constitutes the circuit of lighting is in the light-off state, and the main light source that is made of high-power LED that constitutes the circuit of lighting is in lighting lamp state, trigger the delay switch circuit timing and begin this moment, after the time of setting, delay switch circuit output low level signal then makes ternary output with door become low level, and trigger switch disconnects, the secondary light source lamp is bright thereby normal disconnection battle of control relay, main light source lamp are gone out.In this double-brightness impression LED lamp circuit, make secondary light source by low power LED lamp and can realize that the stair corridor has certain brightness at night, thereby reached the defective that overcomes owing to the too black fear that produces of corridor.
But above-mentioned double-brightness impression LED lamp circuit because low power LED lamp is in a kind of normal bright state, impairs its service life.As shown in Figure 3, second trigger switch 18 that is connected in series in the circuit of secondary light-emitting component 15 to be realizing the control to secondary light-emitting component, and the output of light sensing element 11 is connected through signal amplification circuit 19 in the trigger end of this second trigger switch 18 and the light sensing circuit.During daytime, send the photoinduction signal by low level of signal amplification circuit 19 outputs by light sensitive component 11, this low level is controlled second trigger switch, 18 section of being in line states, even electromagnetic relay is normally closed closed, lower powered secondary light source also is in and extinguishes state.Can solve the problem that lower powered secondary light source also is in normal bright state by day thus.
By meeting output waveform shape signal behind the infrared amplification circuit of electrical signal 10 of infrared waves signal process of human body generation, have only the crest value of this waveform signal and trough value to be only to trigger useful signal ternary and door, then can disturb ternary formation with door between the signal of crest value and trough value.In order to overcome this interference, the infrared sensing circuit that constitutes by human-body infrared sensing element 9 and infrared amplification circuit of electrical signal 10 with ternary with input between be connected by the output of the comparator 21,20 of two parallel connections respectively with or the two-way amplitude discriminator that connects and composes of the input of gating element 22.During work, after hot outer amplification circuit of electrical signal 10 output waveform signals, have only when signal during greater than VH with less than VL, two-way amplitude discriminator is just exported high level.
