Abstract
A kind of incremental dimming device, includes：Light modulation button group -- for being input into light modulation signal of intent；Controller -- for the light modulation signal of intent of light modulation button group input is converted into corresponding switching pulse signal；Zero passage switch -- the switching pulse signal for exporting controller is converted into LED power brightness control signal.Its advantage is using MCU controls, makes the big simplification of circuit, is not likely to produce false triggering, need to only click on and once can just realize 6 grades of light modulations.
Description
Technical field
This utility model relates to the circuit arrangement of general electric light source, is related to the control of electric light source, espespecially a kind of classification
Light modulating device.
Background technology
With the development of science and technology, semiconductor lighting is each because being widely used in the features such as energy-saving and environmental protection, life-span length
Individual field, particularly high-powered LED lamp.During the use of LED, sometimes light can be too strong or dark and has influence on photograph
Obvious results fruit, needs to be dimmed.The brightness of illumination of current LED is fixed mostly, although also have some light adjusting systems, but
Existing light adjusting system is usually relatively complex and price is high, therefore can not meet the demand of a variety of applied environments.China
Patent of invention ZL200510072474.8 discloses a kind of fluorescent lamp ballast of incremental dimming, and describing one kind can be by opening
Close the fluorescent lamp ballast of light modulation.But the fluorescent lamp ballast cannot be directly used to LED.
Prior art also has incremental dimming, uses mechanical switch to trigger dimmer for light control, such as five-part form, from
100% brightness is transferred to 5% brightness and is accomplished by switching 5 times, takes and incremental dimming device can only circulate light modulation, can only plus can not
When subtracting, easy false triggering more than number of operations, and switching, power surges electric current is big, serious to electric network pollution.
Content of the invention
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of grading automatical light modulating device.
This utility model solves the technical scheme adopted by its technical problem：A kind of grading automatical light modulating device is provided,
It is characterized in that including：
Light modulation button group -- for being input into light modulation signal of intent；
Controller -- for the light modulation signal of intent of light modulation button group input is converted into corresponding switching pulse signal；
Zero passage switch -- the switching pulse signal for exporting controller is converted into the brilliance control letter of LED power
Number.
Preferably：
The light modulation button group includes multiple mechanical types or touch-key.
The controller adopts STM32F103_48Pin ic circuits.
The switching pulse signal is：Single low level pulse signal, pulsewidth is 100mS.
The beneficial effects of the utility model are：Using MCU controls, the big simplification of circuit is made, false triggering is not likely to produce, is only needed a little
Hit.
Description of the drawings
The utility model will be further described below in conjunction with the accompanying drawings.
Fig. 1 is electrical structure block diagram of the present utility model.
Fig. 2 is electrical structure schematic diagram of the present utility model.
Fig. 3 is that this utility model is used for the power principle figure to system power supply.
Fig. 4 is that this utility model mode of operation journey fills schematic diagram.
Specific embodiment
Referring to accompanying drawing 1, a kind of incremental dimming device of this utility model, it is characterised in that include：
Light modulation button group 1-- is used for being input into light modulation signal of intent；
Controller 2-- is used for for the light modulation signal of intent that light modulation button group 1 is input into being converted into corresponding switching pulse letter
Number；
Zero passage switch 3-- is used for the brilliance control that the switching pulse signal that controller 2 is exported is converted into LED power 4
Signal.
In embodiment of the present utility model：
The light modulation button group includes 7 mechanical types or touch-key K1--K7.
The controller 2 adopts STM32F103_48Pin ic circuits.
Dimming operation state is referring to Fig. 4.
