1. the simulation of daylight under this utility model can realize underground activities environment so that underground activities personnel's
Biological clock is consistent with normal bio clock, and the health to staff that lacks reducing underground environment daylight causes not
Good impact；
Circuit structure the most of the present utility model is simple, and cost is relatively low, can promote and make in underground activities environment
With.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of bionical illuminator of LED, including touch screen, microprocessor, power subsystem,
PWM dimming unit and LED light source unit, described touch screen, clock unit and sensor unit are all with micro-
Processor input connects, and described power subsystem is connected with LED light source unit by LED drive unit,
PWM dimming unit input is connected with power subsystem, and outfan connects with the simulation light modulation of LED drive unit
Mouth connects.
Described power subsystem is for powering for LED drive unit.
Preferably, described LED drive unit includes LED constant-current driver, for obtaining from microprocessor
Energy, output current value.
Preferably, described PWM dimming unit includes that switch element, current generating unit and electric current output are single
Unit, described switch element, current generating unit and current output unit are sequentially connected in series.Institute's current generating unit
For producing electric current, described circuit output unit when switching means conductive, it is used for accessing current generating unit
The electric current of output, and described electric current is exported to LED drive unit.
Work process is as follows:
Sensor unit gathers ambient light illumination, and transmits ambient light illumination information to microprocessor, clock
Unit provides clock information, microprocessor integrated environment illuminance information and clock information, described clock information
With the time consistency on ground, and clock information and ambient light illumination information are shown by touch screen, use
Family inputs control signal by touch screen to microprocessor, and described control signal inputs to microprocessor, micro-place
Reason device receives control signal, and is converted to control signal drive signal, drives Signal Regulation LED light source list
The illuminance of unit, meanwhile, described PWM dimming unit outfan connects with the dimming interface of LED drive unit
Connecing, PWM dimming unit includes switch element, current generating unit and current output unit, switch element
Producing electric current during conducting, circuit output unit accesses the electric current of current generating unit output, and by described electric current
Output is to LED drive unit, and then regulation LED drive unit output current value, and microprocessor is by LED
The current value of driver element output carries out data process, and is converted to drive signal by the result that data process,
And then microprocessor is by driving signal to control the illuminance of LED light source unit, this utility model passes through micro-place
Reason device and PWM dimming unit carry out the regulation of illuminance jointly to LED light source unit so that LED light
The light that source unit sends is close to daylight, and under different clocks, the illuminance sent is different, to meet people
The requirement of body biological clock.
Although detailed description of the invention of the present utility model is described by the above-mentioned accompanying drawing that combines, but not to this
The restriction of utility model protection scope, one of ordinary skill in the art should be understood that in technology of the present utility model
On the basis of scheme, those skilled in the art need not to pay various amendments that creative work can make or
Deformation is still within protection domain of the present utility model.
