Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not paying creative work premise, broadly fall into the scope of this utility model protection.
As depicted in figs. 1 and 2, a kind of permanent illuminance LED controller based on WiFi, including sensing unit and light modulation driver element, sensing unit is connected by WiFi with light modulation driver element, it is achieved the communication of data.Sensing unit for monitoring of environmental brightness value and set need brightness value, required brightness value by WiFi by sensing unit be sent to dim driver element, dim driver element according to required brightness value, regulate the brightness of corresponding LED.
Sensing unit includes illuminance transducer the 1, first single-chip microcomputer the 2, first WiFi module 3, reading mode button 4, display screen 5, brightness increase button 6 and luminance-reduction button 7, and illuminance transducer the 1, first WiFi module 3, reading mode button 4, display screen 5, brightness increase button 6 and is all connected with the first single-chip microcomputer 2 with luminance-reduction button 7.Typically, illuminance transducer 1 can be APDS9960, and illuminance transducer 1 monitors the brightness value in current environment.First single-chip microcomputer 2 is connected with illuminance transducer 1 by I2C interface, it is achieved be acquired the brightness value in environment, is then shown by display screen 5, carries out the reference of brightness for user, meanwhile, facilitates brightness value that is follow-up and that preset to compare.Reading mode button 4, brightness increase button 6 and the most corresponding preset brightness value of luminance-reduction button 7, after pressing corresponding button, dimming commands, according to the brightness value gathered, is sent to dim driver element by the first WiFi module 3, regulates the brightness of LED by the first single-chip microcomputer 2.The illuminance setting value of reading mode button 4 acquiescence is 400Lux, meets general reading requirement.Brightness increases button 6 and increases 50Lux brightness every time, and luminance-reduction button 7 reduces 50Lux brightness every time.Button 6 can be increased by brightness and increase setting brightness value, reduce setting value by luminance-reduction button 7, thus regulation sets brightness value freely.
Light modulation driver element includes that the second WiFi module 8, second singlechip 9 and LED drive chip 10, second singlechip 9 are connected with the second WiFi module 8 and LED drive chip 10.LED and light modulation driver element utility power adapter are as DC power supply.LED drive chip 10 and peripheral circuit thereof constitute PWM light adjusting circuit, and PWM light adjusting circuit is connected with power supply adaptor.Typically, LED drive chip 10 can be PAM2861.Second singlechip 9 resolves the dimming commands data that the second WiFi module 8 receives, and produces satisfactory pwm signal, and PWM light adjusting circuit is according to the brightness of this pwm signal regulation LED.
When the current illumination value that illuminance transducer 1 measures environment less than reading mode button 4 or increases the brightness value set by button 6 and luminance-reduction button 7 by brightness, first single-chip microcomputer 2 sends increase brightness value by serial ports to the first WiFi module 3 and instructs, order is forwarded on the second WiFi module 8 of dimming driver unit by the first WiFi module 3 by radio communication, second singlechip 9 completes the detection of order, increase the dutycycle 1% of PWM dim signal, PWM dim signal is sent to LED drive chip 10, and LED drive chip 10 regulates the brightness of LED；Otherwise, if the brightness value of illuminance transducer 1 current detection is higher than the brightness value set, first single-chip microcomputer 2 sends the instruction reducing brightness value, order is forwarded on the second WiFi module 8 of dimming driver unit by the first WiFi module 3 by radio communication, second singlechip 9 interpretation is the instruction reducing brightness value, reducing the dutycycle 1% of PWM dim signal, PWM dim signal is sent to LED drive chip 10, and LED drive chip 10 regulates the brightness of LED.Until illuminance transducer 1 detect the brightness value in environment be changed to set illumination 5% in the range of, sensing unit stop send dimming commands, sensing unit and light modulation driver element stopping communicate.Therefore, this utility model can carry out fine regulation by PWM dim signal to the power of LED, thus realizes its brightness is fine-tuned.Sensing unit can move flexibly, and user can be placed on wanting to realize on the desk desktop that permanent illumination controls, bedside cabinet is first-class, realizes the permanent illumination to specific region flexibly and controls.
Preferably, light modulation driver element can be provided with several, and light modulation driver element is connected with respective LED lamp bead respectively.One sensing unit can corresponding multiple light modulation driver elements, the dimming commands that i.e. sensing unit transmits is simultaneously sent to multiple light modulation driver element by the first WiFi module 3 with the pattern of broadcast, thus drive multiple different LED, it is achieved control while multiple LED.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
