Foregoing control device 3 comprising an interface circuit 30 (Interface circuit), a microprocessor 31 (MCU) and
One power management supply 32, the interface circuit 30 is electrically connected with the fan 20, OPTICAL SENSORS 41 and microprocessor 31, and
It is the medium that microprocessor 31, OPTICAL SENSORS 41 and fan 20 were transformed into each other and transmitted signal, such as signal of OPTICAL SENSORS 41
For analog signal through interface circuit 30 be converted into the microprocessor 31 can computing digital signals.
Aforementioned microprocessor 31 produces one to control signal according to the optical sense signal, is sent to the power management supply
32, that is, microprocessor 31 receives optical sense signal by interface circuit 30, to learn the brightness of each LED unit, and
The control signal is produced after computing is done to optical sense signal simultaneously, the power management supply 32 is sent to, power management is supplied
Device 32 is answered according to the brightness of the control signal adjustment control LED unit 10 for receiving, effectively to allow each LED unit 10 to tie up
Hold in identical brightness, and then effectively reach the effect of brightness uniformity.
The power management supply 32 is electrically connected with the microprocessor 31, fan 20, the input electricity of LED unit 10 and
Source, and its be used to supply respectively power supply to fan 20 and LED unit 10 outside, in turn can be according to the control signal for receiving, control
System adjustment output reaches the brightness of adjustment LED unit 10 to the voltage or switching frequency of LED unit 10.
Again refering to shown in Fig. 2, the microprocessor 31 is with more the function that gives a warning, that is, microprocessor 31 is according to light sensing
Signal learns the brightness of each LED unit 10, and the brightness of each LED unit 10 is right compared with its interior setting brightness value,
If the brightness of a certain LED unit 10 is less than the setting brightness value, one first telltale signal to the terminal for linking is sent immediately
Device 6, makes terminal installation 6 learn that the LED unit 10 in somewhere occurs abnormal (as damaged) from the first telltale signal for receiving, so as to
Maintenance process is done immediately.
Therefore, it is integrated into setting together by the LED unit 10 of the present invention, fan 20, OPTICAL SENSORS 41 and control device 3
Meter so that effectively control each LED unit 10 to maintain identical brightness, and then effectively make LED modules 1 reach brightness uniformity it
Effect.
Refering to shown in Fig. 3,4, second preferred embodiment of the present invention, the embodiment substantially with foregoing first preferred embodiment
Identical, something in common no longer superfluous words is at difference in the second preferred embodiment：The automatic control system further includes at least one temperature
Degree sensor 42, the temperature-sensitive sticker 42 is arranged at the adjacent position of fan 20, and is electrically connected with the interface circuit 30, and temperature
The temperature of the matching correspondence fan 20 of sensor 42, detecting ambient temperature and the surrounding environment of each fan 20, to produce one
Temperature sensing signal, sends the control device 3 to.
Another person is aided with refering to Fig. 4, and user can set according to space in light-emitting device 5 and outward appearance in advance when specific implementation
The demand of meter, light-emitting device 5 is installed in by fan 20 together with foregoing OPTICAL SENSORS 41, temperature-sensitive sticker 42 and LED unit 10
It is interior, that is, the side of each LED unit 10 each fan 20 of correspondence in the light-emitting device 5, and each OPTICAL SENSORS 41 is adjacent
Correspondence each LED unit 10, and each temperature-sensitive sticker 42 is then adjacent to should each fan 20.
And person, the optical sense signal that aforementioned microprocessor 31 is transmitted according to interface circuit 30 is transported with temperature sensing signal
Calculate, to produce foregoing control signal respectively and one drive signal, the driving signal feasible to be embodied as PWM signals, microprocessor one
Device 31 produces the driving signal according to temperature sensing signal, and adjusts the pwm value of the driving signal, and then adjusts fan 20
Rotating speed.
Specifically, the microprocessor 31 receives optical sense signal, temperature sensing signal respectively by interface circuit 30, and
The brightness of each LED unit 10 is learnt from optical sense signal, while the control signal is produced after computing is done to optical sense signal,
Send the power management supply 32 to, make power management supply 32 according to the control signal adjustment control LED for receiving
The brightness of unit 10.
Then, the microprocessor 31 learns temperature (the i.e. foregoing external environment temperature at each position from temperature sensing signal again
The temperature of degree and the surrounding environment of each fan 20), and the driving signal is produced after doing computing to temperature sensing signal simultaneously, connect
And transmit the driving signal to fan 20 through the interface circuit 30, to control the rotating speed of each fan 20, and then appropriate adjustment control
The air quantity that each fan 20 each LED unit 10 of correspondence is discharged is made, therefore so that on the one hand can make each LED unit
10 maintain identical operating temperature and roughly the same attenuation, and the effect of Homogeneouslly-radiating, the opposing party are effectively reached in turn
Face then effectively allows each LED unit 10 to maintain identical brightness, and then effectively reaches the effect of brightness uniformity.
Furthermore, again refering to shown in Fig. 4, the microprocessor 31 has with more the function that gives a warning, the function that gives a warning
Following two aspects:
Wherein the first aspect is that microprocessor 31 learns the brightness of each LED unit 10 according to optical sense signal, and by every LED
The brightness of unit 10 is right compared with the setting brightness value in it, if the brightness of a certain LED unit 10 is less than the setting brightness value,
Foregoing first telltale signal to the terminal installation 6 for linking is sent immediately, terminal installation 6 is learnt from the first telltale signal for receiving
There is abnormal (as damaged) in the LED unit 10 in somewhere, soon to do maintenance process.
Second aspect is that microprocessor 31 learns the temperature at each position according to temperature sensing signal, and by each position
Temperature is right compared with its interior design temperature (such as design temperature is 70 degree), if a part temperature exceedes the design temperature, sends out
Terminal installation 6 of one second telltale signal to linking is sent, terminal installation 6 is learnt this position temperature from the second telltale signal for receiving
There is exception in degree, and then understand that the fan 20 at this position of correspondence may be in damaged condition, soon to repair.
The above, by the LED unit 10 of the present invention, fan 20, OPTICAL SENSORS 41, temperature-sensitive sticker 42, control dress
Put 3 and be integrated into design together so that not only identical work temperature can be maintained with each LED unit 10 of appropriate Boiler pressure control
Degree, and maintaining outside roughly the same attenuation, and can control each LED unit 10 and maintain identical brightness, and then effectively
LED modules 1 are made to reach the effect of radiating and brightness uniformity.
In sum, the present invention compared to known with following advantages:
1. there is the effect for reaching brightness uniformity；
2. have and reach the uniform effect of radiating；
3. each LED unit is maintained identical brightness；
4. each LED unit is maintained the roughly the same attenuation of identical operating temperature.
Only the above, the only preferably feasible embodiment of the present invention, such as using method, the shape that the present invention is above-mentioned
Shape, construction, device change for it, should all be contained in the interest field of this case.
