It realizes, needs to acquire a certain number of data and compare again by software control light modulation, while needing to match preparation controller, at
This height, low efficiency.The utility model provides a kind of non-pole light regulating circuit system for rainshed signal lamp, and hardware may be implemented
Light modulation in real time regulates and controls without software, efficiency is improved while reducing costs.
Utility model content
The purpose of the utility model is to provide a kind of non-pole light regulating circuit systems for rainshed signal lamp.
Above-mentioned purpose is realized by following technical scheme:
A kind of non-pole light regulating circuit system for rainshed signal lamp, composition includes: rectification reduction voltage circuit, and described is whole
It flows reduction voltage circuit and connects regulating circuit, feed circuit, the regulating circuit connection feed circuit.
A kind of non-pole light regulating circuit system for rainshed signal lamp, input voltage is exported through resistance R1, defeated
Outlet is connected with resistance R2 and resistance R3 and is grounded again, three-terminal voltage-stabilizing pipe plus earth, and cathode connects voltage output end, sampling end access
The resistance R2 and the resistance R3 connecting node, light probe and filter capacitor C1 are incorporated to the resistance R3.
The utility model has the advantages that
1. the utility model is a kind of non-pole light regulating circuit system for rainshed signal lamp, simple with circuit structure,
The advantages that practical.The feed circuit for devising corresponding function simultaneously, improves the practicability of circuit system, it is ensured that system
The stability of circuit.
2. the utility model is suitable for the adjusting of rainshed signal lamp brightness, non-pole light regulating is realized by hardware light probe, is adjusted

Specific embodiment
Embodiment 1:
A kind of non-pole light regulating circuit system for rainshed signal lamp, composition includes: rectification reduction voltage circuit, and described is whole
It flows reduction voltage circuit and connects regulating circuit, feed circuit, the regulating circuit connection feed circuit.
Embodiment 2:
According to a kind of non-pole light regulating circuit system for rainshed signal lamp described in embodiment 1, input voltage is through resistance
R1 output, connects with resistance R2 and resistance R3 in output end and is grounded again, three-terminal voltage-stabilizing pipe plus earth, cathode connects voltage output
End, the sampling end access resistance R2 and the resistance R3 connecting node, light probe and filter capacitor C1 are incorporated to described
Resistance R3.
Embodiment 3:
A kind of non-pole light regulating circuit system for rainshed signal lamp, the resistance according to Examples 1 and 2
R2 is as upper biasing resistor, and the resistance R3 is as below-center offset resistance.Since the three-terminal voltage-stabilizing pipe sampling end voltage is solid
It is fixed constant, when the light probe variation of resistance value occurs with the variation of external environment brightness, with the resistance R3 group
At parallel circuit entirety resistance value can also change, since the resistance R2 and the resistance R3 connecting node voltage are protected
Hold constant, then output voltage changes with the variation that ambient light is shone, to realize non-pole light regulating.
The above descriptions are merely preferred embodiments of the present invention, is not limited to utility model.In embodiment
It is only the working principle for illustrating the utility model by taking the non-pole light regulating circuit system of rainshed signal lamp as an example, is not limited in rain
The non-pole light regulating circuit system of canopy signal lamp.All spirit in utility model within principle, equally replace by made any modification
It changes, improve, should be included within the protection scope of utility model.
