Abstract
The invention discloses an LED lamp control circuit and a control method thereof. The LED lamp control circuit comprises a controller used for controlling the on-off and the brightness of an LED lamp, an infrared ray sensor used for detecting whether a person exists within a certain range or not and sending a signal to the controller when a person is detected, a photosensitive sensor used for detecting an environmental brightness value and transmitting information to the controller, a sound sensor used for detecting decibels and transmitting information to the controller, and a smog sensor used for sending a signal to the controller in case of a fire. The LED lamp is enabled to change the brightness value according to the environmental brightness value, people can increase the brightness value of the LED lamp through sounds, and the LED lamp flickers for warning in case of a fire.
Description
Technical field
The present invention relates to a kind of LED lamp control circuit and control method.
Background technology
The LED of street, corridor and stair etc. can be in dark and there is people to automatically turn on through out-of-date, thus both
The purpose of illumination can be reached, improve the utilization ratio of illuminating lamp, the most do not waste electric energy.But, the function that LED automatically turns on after the most only having in people walks about certain limit at present, it also cannot send different illumination brightness according to the ambient brightness of different time sections, and the illumination brightness of LED also cannot be controlled by people, more inconvenience.
Summary of the invention
The technical problem to be solved is, a kind of LED lamp control circuit is provided, it makes LED can change its brightness value according to ambient brightness value, and people can make LED increase brightness value by sound, and during breaking out of fire, LED flashes to play warning function.
For solving above-mentioned technical problem, the LED lamp control circuit that the present invention provides, it includes:
One controller, for controlling keying and the brightness of LED；
One infrared ray sensor, whether around certain limit in have people, and transmit a signal to controller when people having been detected if being used for detecting；
One light sensor, is used for detecting ambient brightness value and transmitting information to controller；
One sound transducer, is used for detecting sound decibel and transmitting information to controller；
One Smoke Sensor, for transmitting a signal to controller when breaking out of fire.
The invention also discloses a kind of LED lamp control method:
When infrared ray sensor detects and around has people, transmitting a signal to controller, controller controls LED and opens；
And ambient brightness value now is transmitted to controller by light sensor, and controller controls the brightness value of LED according to ambient brightness value so that the brightness value of LED and ambient brightness value sum are 5000 cd/m；
And after LED is opened, if sound transducer detects the sound more than A decibel, controller controls the brightness value of LED and increases 1000cd/m；
And when Smoke Sensor detects breaking out of fire, Smoke Sensor transmits a signal to controller, controller controls LED flicker.
After using above structures and methods, the present invention compared with prior art, has the advantage that
The invention enables LED can change its brightness value according to ambient brightness value, that is when daytime is brighter, when LED is opened, brightness value is relatively low, when evening is dark, when LED is opened, brightness value is higher, and people can make LED increase brightness value by sound, when that is needing to make LED increase brightness, people can send the sound of bigger decibel, so that LED increases brightness value so that can conveniently control LED brightness value；
And the invention enables when breaking out of fire, LED can flash, and plays warning function, so that people can find fire in time, escape in time.
Accompanying drawing explanation
Fig. 1 is the electrical block diagram of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in more detail below in conjunction with the accompanying drawings.
As shown in Figure 1, LED lamp control circuit of the present invention includes a controller, an infrared ray sensor, a light sensor, a sound transducer and a Smoke Sensor.
Controller is for controlling keying and the brightness of LED.
Whether infrared ray sensor is used for detecting around has people in certain limit, and transmits a signal to controller when people having been detected.
Light sensor is used for detecting ambient brightness value and transmitting information to controller.
Sound transducer is used for detecting sound decibel and transmitting information to controller.
The signal output part of Smoke Sensor electrically connects with the signal input part of controller, for transmitting a signal to controller when breaking out of fire.
The control method of above-mentioned LED lamp control circuit is as follows:
Embodiment one
When infrared ray sensor detects and around has people, transmitting a signal to controller, controller controls LED and opens.
And ambient brightness value now is transmitted to controller by light sensor, and controller controls the brightness value of LED according to ambient brightness value so that the brightness value of LED and ambient brightness value sum are 5000 cd/m.
And after LED is opened, if sound transducer detects the sound more than 40 decibels, controller controls the brightness value of LED and increases 1000cd/m.
And when Smoke Sensor detects breaking out of fire, Smoke Sensor transmits a signal to controller, controller controls LED flicker.
Embodiment two
When infrared ray sensor detects and around has people, transmitting a signal to controller, controller controls LED and opens.
And ambient brightness value now is transmitted to controller by light sensor, and controller controls the brightness value of LED according to ambient brightness value so that the brightness value of LED and ambient brightness value sum are 5000 cd/m.
And after LED is opened, if sound transducer detects the sound more than 50 decibels, controller controls the brightness value of LED and increases 1000cd/m.
And when Smoke Sensor detects breaking out of fire, Smoke Sensor transmits a signal to controller, controller controls LED flicker.
Embodiment three
When infrared ray sensor detects and around has people, transmitting a signal to controller, controller controls LED and opens.
And ambient brightness value now is transmitted to controller by light sensor, and controller controls the brightness value of LED according to ambient brightness value so that the brightness value of LED and ambient brightness value sum are 5000 cd/m.
And after LED is opened, if sound transducer detects the sound more than 60 decibels, controller controls the brightness value of LED and increases 1000cd/m.
And when Smoke Sensor detects breaking out of fire, Smoke Sensor transmits a signal to controller, controller controls LED flicker.
Below only applying preferably example to be made that explanation with regard to the present invention, but be not to be construed as limitations on claims, the structure of the present invention can have other to change, and is not limited to said structure.In a word, all various changes made in the protection domain of the independent claims of the present invention are the most within the scope of the present invention.
