The stability of foot voltage.
The Schmidt trigger trigger characteristic that used time base chip 555 is constituted, input signal varying level can lead to output not
With the output signal of level.(Va is voltage at A points, and Vc is voltage at C points) at that time, when the 555 output letter of output pin 3 of base chip
Number end output high level, Q1 conducting;At that time, 555 output pin of base chip, 3 output signal end output signal remained unchanged when, Q1
It tends to remain on constant;At that time, 555 output pin of base chip, 3 output signal end exported low level, Q1 cut-offs when.Due to must
Must meet condition or when base chip signal output can just overturn, the conducting state of Q1 can just change.As shown in figure 4,
In the utility model embodiment, i.e., when natural lighting generating process causes or when, lamp condition can just change, and avoid road
Lamp because just light or other reasons caused by photo resistance RG be illuminated by the light intensity and change when, when 555 output pin 3 of base chip
Output signal end output state is overturn, and the phenomenon that cause LED lamp holder to flicker.
As shown in figure 4, control switch be one-way SCR Q1, the applying of forming of base chip 555 is close when ON-OFF control circuit is
When special trigger circuit, one-way SCR Q1 control terminals with when 555 signal output end (pin 3) of base chip between connect protection electricity
Road, the protection circuit include the first diode VD1 and the first current-limiting resistance R1, base chip when the first diode VD1 anodes connect
555 signal output end (pin 3), cathode are connected the control terminal of connection one-way SCR Q1 after the first current-limiting resistance R1.Control
Signal from when 555 signal output end of base chip be input to Q1 control terminals when, play the role of one-way conduction, and it is big to limit electric current
It is small, protect Q1;And electric current reverse breakdown is prevented, base chip 555 when protection.
Further, 555 power input shunt regulating circuit (not shown) of base chip, base core when which is when
555 positive voltage end of piece provides burning voltage.
Specifically, as shown in figure 4, regulator circuit be voltage-stabiliser tube regulator circuit, be made of voltage-stabiliser tube ZD1, voltage-stabiliser tube ZD1
555 power input of base chip when being connected in parallel on, voltage-stabiliser tube ZD1 anodes connect the power supply positive input terminal of LED module 130, and cathode connects
110 power supply positive output end of drive module is connect, base chip 555 provides burning voltage when being.
Further, the first filter capacitor C1 of the both ends voltage-stabiliser tube ZD1 parallel connection.
In a preferred embodiment, ZD1 is the voltage-stabiliser tube of 12V, 555 supply voltage of base chip when stablizing.
In a preferred embodiment, as shown in figure 4, when 555 positive voltage end of base chip with 110 power supply of drive module just
The second current-limiting resistance R2 of output end series connection.555 input voltage of base chip when limitation, avoids input current excessive, ensures control mould
Circuit element works normally in block 120.
Below by taking Fig. 4 as an example, the operation principle of the utility model Light control road lamp circuit is described in detail.
Circuit operation principle:When night no light, photo resistance RG is in high resistant, and A point voltages Va is relatively low, is designed as (Vc C
Point place voltage), constantly base chip 555 exports high level for this, and unidirectional silicon Q1 is connected, LED module 130 by drive module 110 and
The conducting circuit of unidirectional silicon Q1 compositions is electrically connected with city, and LED street lamp is bright.
It is disconnected at this time to LED module 130 and drive module 110, it is necessary to which the output state of base chip 555 occurs when meeting
Overturning, can just be such that Q1 ends, and disconnect the access of LED module 130 and drive module 110.
When dawn, since illumination increases, low-resistance is gradually presented in photo resistance RG, and Va gradually rises at this time, at that time, Shi Jixin
Piece 555 exports low level, unidirectional silicon Q1 cut-offs, and LED module 130 is disconnected with drive module 110, and street lamp extinguishes.
Foregoing description can be seen that just because of when 555 output signal output state of base chip overturning occurs must satisfy
Or this specific condition, so street lamp will not because just light or other reasons caused by intensity of illumination suffered by photo resistance RG occur
When variation, when base chip 555 output state overturn, the phenomenon that so as to cause LED lamp holder optical flare.
Above-mentioned Light control road lamp circuit adjusts illumination spot by the first variable resistance RP1, adapts it to the intensity of illumination of various regions
Change lamp condition, meanwhile, the Schmidt trigger constituted using base chip when 555 is connected with unidirectional silicon, controls lighting change
When change lamp condition, wherein only when lighting change reaches certain degree, lamp condition can just change, and avoid
The problem of critical flicker of street lamp.The control module of above-mentioned Light control road lamp circuit can be made into the module of an entirety, be applied directly to
Light-operated purpose is realized between drive module and LED module.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
