Embodiment

The utility model is further described with reference to embodiment.

As shown in figs 1-9, a kind of LED intelligent dimming devices suitable for voltage light modulation, including detection module, hand-held remote control Module, dimming controlling module and LED, the detection module connect LED with hand-held remote control module by dimming controlling module Lamp, wherein：

The detection module includes the first potentiometer, the second potentiometer, infrared sensor, the first single-chip microcomputer and the first radio frequency Chip, a photo resistance is also included in the detection module, and the photo resistance connects the first single-chip microcomputer, first current potential The first knob is provided with device, the first knob is used for the resistance for adjusting slide rheostat on the first potentiometer, second current potential The second knob is provided with device, the second knob is used for the resistance for adjusting slide rheostat on the second potentiometer；

The key-press module includes switch key and light level button；The light level button include one-level button, Two level button, three-level button and level Four button.

The first knob is provided with outside first potentiometer, the first knob can control the slip variable resistance on the first potentiometer Device resistance, it is lighting time corresponding to the slide rheostat resistance（Time threshold）, i.e. adjusting knob can set lighting time, Had when adjusting the first knob a corresponding magnitude of voltage by inside ADC be transformed into digital quantity be transmitted to potentiometer detect End.

The second knob is provided with outside second potentiometer, the second knob can control slide rheostat on the second potentiometer Resistance, be the delay time that people think setting corresponding to the slide rheostat resistance, i.e. adjusting knob is regulating delay time, A corresponding magnitude of voltage is had when adjusting the second knob can equally be transformed into digital quantity and be transmitted to current potential by the ADC of inside Device test side, then delay function is achieved by the timer inside the first single-chip microcomputer.

People is in user-defined light threshold value（When turned on light into needs）Interior entrance is turned on light automatically.Whether detect light Reach threshold data, if the infrared sensor reached in threshold value and control box detects that someone enters, and pass through photo resistance Whether detection light reaches light threshold value, and signal can be transmitted in dimming controlling module by the first single-chip microcomputer by the first radio frequency chip The 3rd single-chip microcomputer, so as to control the light on and off of LED, be specially：Potentiometer can reflect ambient by the change of voltage Strong and weak change, when voltage reaches threshold value, magnitude of voltage is changed into data signal and passes through the first radio frequency chip by its internal ADC conversion Send dimming controlling module to, realize the control to LED switch.

3rd single-chip microcomputer is connected with low pass filter by the 3rd single-chip microcomputer pin, then likewise, peripheral LED circuit It is connected by the 3rd single-chip microcomputer pin.

Peripheral LED circuit is exactly to be connected with the 3rd single-chip microcomputer in dimming controlling module with the relation of dimming controlling module, 3rd single-chip microcomputer can export 0 or 1,0 and go out 1 bright control LED peripheral circuits, and how dim, then passes through the photograph at hand-held remote controller end Bright rank button carrys out the dutycycle of control single chip computer output square wave, and due to suspenopsia effect, people can be appreciated that LED is different degrees of It is bright weak.

User according to the needs of oneself setting when people enter it is fashionable needs turn on light walked with people after need delay how long Automatically turn off the light, setting means is：The knob of turn first and second, a potentiometer is all corresponded to inside two knobs respectively （3296W-103 10K）, adjusting knob can change inside resistance, change resistance after, have a corresponding electricity Pressure value, pass through the first single-chip microcomputer（MSP430）ADC conversions after corresponding data signal be time threshold and light threshold value.

When ambient reaches the threshold value of user's setting, system starts light data acquisition, such as Fig. 9 light data Local circuit is gathered, the power of light can change the resistance size of photo resistance, and corresponding magnitude of voltage can also change simultaneously Become, magnitude of voltage can equally pass through the first single-chip microcomputer（MSP430）ADC be converted into data signal and pass through the first radio frequency chip （PL1167）Send dimming controlling module to.

When people enters room, infrared ray sensor（LF5038F）It can detect.When ambient reaches user's given threshold Descendant enters room, the first radio frequency chip（PL1167）Data signal can be sent to dimming controlling module.Dimming controlling module In the first radio frequency chip（PL1167）The 3rd single-chip microcomputer is passed to by input after receiving（STM32F103）, the 3rd is single Piece machine gives one high level of LED peripheral drive circuits immediately, and LED is bright.

When people feels dissatisfied to indoor light, the power of light, remote control appliance are can adjust using hand-held remote control module Body running mode is：When 1 in the bright weak button that people triggers regulation light, 2,3,4 button, second singlechip （TMS370C256A）Minimum system receives a high level, and the second radio frequency chip (PL1167) is launched to dimming controlling module to be believed Number, after reception signal, shone by its 3rd internal single-chip microcomputer (STM32F103) minimum system and low pass filter effect control Bright circuit, so as to complete to dim work.

When people withdraws from a room, infrared sensor（LF5038F）It can equally detect, now first in detection module Single-chip microcomputer（MSP430）Start timing, when reaching the time threshold of user's setting, likewise, voltage signal can be single by first ADC conversions inside piece machine are become data signal and send dimming controlling module to by the first radio frequency chip PL1167 again, are adjusted After radio frequency chip PL1167 reception signals in photocontrol module, driven by the 3rd single-chip microcomputer (STM32F103) to LED peripheries One low level of dynamic circuit, LED are gone out.

Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
