The transmitter 300 and blower fan 400 of output voltage, the radiation sensor 200 are arranged on the top of the display screen, the pick-up
Device 300 is arranged on below display screen, and the transmitter 300 connects the blower fan 400.
A kind of outdoor LCD energy-saving control systems of the present invention, it in LCD energy-saving control systems out of doors by setting one
For sensing the radiation sensor 200 of sunshine and the blower fan 400 of different wind speed can be controlled, under different sunlight intensities,
When radiation sensor 200 receives different solar radiation values, the outdoor LCD energy-saving control systems can be automatically according to different
Solar radiation value controls the running speed of blower fan 400 so that it can run at high speed in the case where sunshine is strong, at the cloudy day
Or low-speed running or closing in the case of night, so as to realize that intelligent control blower fan is operated, saved while display screen is protected
And the service life of extension blower fan.
In preferred embodiment, the radiation sensor 200 is solar radiation sensor.Sunshine has infrared ray, ultraviolet
The difference light such as line and x-ray, can pass through through AR glass and apply the anti reflection glass on display screen 100, and
Substantial amounts of heat is produced on display screen 100, accelerates the aging speed of display screen 100, service life is reduced.The present invention uses spoke
Penetrate sensor to collect solar radiation value, further control blower fan to operate by transmitter the solar radiation value of collection,
Realize that the operating of blower fan is directly proportional to the intensity of sunshine, realization automatically controls blower fan running speed, reduce the effect of energy consumption.
Specifically, transmitter is the conversion for the output signal of sensor being changed into the signal that can be recognized by controller
Device.Further, transmitter 300 of the present invention is DC voltage transmitter, and it uses direct current to ensure Electrical Safety,
And simple structure, outdoor advertisement machine can be facilitated to be used backwoodsman.Heretofore described radiation sensor and direct current
Transmitter together constitutes with the monitoring signals source for automatically controlling sunlight intensity, and it passes through the DC voltage transmitter internal power
Conversion, is converted into relay control signal by detected radiation value, the operating of blower fan is controlled by this signal, such
Rainy day, cloudy day or evening basic fan are inoperative, only can just be operated when there is sunlight, extend the service life of blower fan.
Preferably, blower fan 400 of the present invention is axial fan.Axial fan simple structure, its impeller peace
In cylindrical chassis, the arbor of motor is directly connected with impeller, when motor works, the impeller rotation of axial fan
Turn, air is sucked by air inlet, discharged by impeller and diffusion barrel.It is highly preferred that can also be after the display screen 100
Lower section sets a blower fan 400 again, can make its better heat-radiation effect.

In 1000r/min be middling speed state；When the rotating speed of blower fan is more than 1000r/min and is high speed shape less than or equal to 3000r/min
State.
Specifically, heretofore described outdoor LCD energy-saving control methods are controllable mode, i.e.,：When detecting the sun
When light radiation value is less than or equal to 50W/ squares, blower fan is closed；It it is 50 ~ 100W/ squares when detecting solar radiation value（Do not include
50W/ squares）Shi Fengji is low speed；It it is 100 ~ 150W/ squares when detecting solar radiation value（Do not include 100W/ squares）Wind
Machine is middling speed；It is rotation at full speed when detecting more than 150W/ squares blower fan of solar radiation value.
Certainly, the present invention can also realize the control to blower fan using switch form, i.e., make a reservation for certain sunshine in advance
Radiation value scope, when radiation sensor 200 detects the solar radiation value for falling into preset range, then controls blower fan 400
Switch, opens blower fan 400 and is operated, and when the solar radiation value detected does not fall within preset range, then closes blower fan
400, the operating that blower fan is controlled by plain mode is realized, so as to realize reduction power consumption, extends service life of fan, while can also
Protect the effect of display screen.
In summary, by a kind of outdoor LCD energy-saving control systems of the present invention and its control method, it passes through at family
