For problem above, this utility model provides a kind of automatic dimming circuit, can be adjusted according to light intensity automatically
Section lamplight brightness, it is easy for installation, and can be easy to use at any time, effectively can solve with manual-lock automatic dimming function
The certainly problem in background technology.
For achieving the above object, this utility model provides following technical scheme：A kind of automatic dimming circuit, including
AT89C51 single-chip microcomputers and illuminating lamp tube, the TA89C51 single-chip microcomputers are connected to signal adapter, brightness display screen, transformation
Device, external power supply and switch and manual locking switch, the signal adapter are connected with light sensor, and the transformator and
Illuminating lamp links together；The manual locking switch surface is respectively arranged with lock release button and is locked and closed button.
Used as a kind of preferred technical scheme of this utility model, the manual locking switch surface adopts phosphor
Material, and the corner of manual locking switch is respectively arranged with installation screw, and the quantity of the installation screw is 4.
Used as a kind of preferred technical scheme of this utility model, the illuminating lamp adopts LED electricity-saving lamps, and using detachable
Structure fixedly mount on the apparatus.
Used as a kind of preferred technical scheme of this utility model, the signal adapter is changed using AD5320 modulus signals
Device, the switch adopt audio-switch.
Compared with prior art, the beneficial effects of the utility model are：The automatic dimming circuit, by arranging light sensor
Device, automatic detection intensity of illumination, the signal that then AT89C51 single-chip microcomputers pass through to receive automatically adjust transformator, then pass through
The change of voltage carrys out the brightness of adjusting illuminating lamp, it is possible to achieve with an automatic light meter, while the switch of the device is easy for installation, using glimmering
Luminescent material is easy to headlamp switch is found when not turning on light at night, while the device can be when illuminating lamp reaches a certain brightness, handss
It is dynamic to close automatic dimming function, you can to make illuminating lamp keep a certain constant luminance, and the device can be complete using audio-switch
The control of illuminating lamp, practical and convenient in pairs.
