Couple with described sampling module and base modules respectively, for comparing sampled voltage and reference voltage, when sampled voltage is more than
Output drive signal after reference voltage, illuminates lamp module and is controlled by described drive signal control illuminating lamp work.
By adopting above-mentioned technical proposal, illuminating lamp work is controlled after automatically display circuit detects dark, entered
Row illumination, makes one convenient when measurement of length is carried out, and the distance of measurement will not be can't see because sight line is bad.
The utility model can be further arranged to, and described illuminating lamp is fixed on the top of the stainless steel rule.
Positioned at stainless steel rule top the light of illuminating lamp can be made more preferable by adopting above-mentioned technical proposal, illuminating lamp
Diverging, reaches the effect being illuminated to stainless steel rule.
The utility model can be further arranged to, and described base modules include the first reference resistance, the second reference resistance
With the 3rd reference resistance, described the first reference resistance and the node of second reference resistance couple the comparison module, institute
The 3rd reference resistance stated is connected ground connection with the second described reference resistance.
By adopting above-mentioned technical proposal, dividing by the first reference resistance, the second reference resistance and the 3rd reference resistance
Pressure is reached for the purpose that comparison module provides reference voltage.
The utility model can be further arranged to, and described 3rd resistor is variable resistor.
By adopting above-mentioned technical proposal, by adjusting variable-resistance resistance and then reaching the mesh for adjusting reference voltage
, the floor of light intensity is can adjust, make illuminating lamp be illuminated work under suitable light.
The utility model can be further arranged to, and described illumination lamp module is provided with protective resistance with described illuminating lamp
Concatenation.
The utility model can be further arranged to, and protective resistance has the effect that partial pressure is protected, and prevent illuminating lamp because wink
When voltage it is excessive and damage.
In sum, the utility model has the advantages that：
Illuminating lamp work is controlled after automatically display circuit detects dark, is illuminated, make one carrying out length
Measurement when it is convenient, the distance of measurement will not be can't see because sight line is bad, it is straight that illuminating lamp is fixed on the stainless steel
The top of chi, illuminating lamp can be such that the light of illuminating lamp preferably dissipates positioned at stainless steel rule top, reach straight to stainless steel
The effect that chi is illuminated.
