Show corresponding numeral.
Logical transition circuit is converted to intensity level signal the logical signal of numeral method numeral, charactron driving electricity
Road drives numeral method, and numeral method module shows corresponding intensity level.
Intensity monitor instrument described in the utility model perceives optical signal by light sensor, and completes optical signal to telecommunications
Number conversion.Signal comparator compares the electric signal and default level value that represent light intensity, determines intensity level, sets five
Intensity level.LED post lights corresponding LED numbers according to intensity level, the different conditions of four LEDs, goes out entirely, one bright three
Go out, two bright two go out, three bright one going out, all light corresponds to light intensity and grown from weak to strong five grades respectively.Logical transition circuit is by intensity level
Signal is converted to the logical signal of numeral method numeral.Nixie tube drive circuit drives charactron using logic level.It is digital
Pipe display module shows corresponding intensity level under drive circuit driving, display numeral 0,1,2,3 and 4 correspond to respectively light intensity by
It is weak to arrive strong five grades.
Described above is only, to preferred embodiments of the present utility model, not scope of the present utility model to be defined, therefore
On the premise of the utility model design spirit is not departed from, this area ordinary skill technical staff is to structure described in the utility model
Make, the equivalence changes that feature and principle are made or decoration, all should fall into protection domain of the present utility model.
