Through the smart phone with bluetooth function, you can start the relevant modes of indoor LED lights: general mode or constant light mode. The general mode is to adjust the switch and brightness of the light; When the external light intensity is greater than this value, the LED light will be turned off. On the contrary, when the external light intensity is less than this value, the LED light will automatically turn on the supplementary light mode, so that the overall light intensity of the environment tends to the set threshold.

When the LED light is on, the light sensor will detect whether there is anyone in the environment in real time. When the infrared light source is not detected, it will notify the control module that the person has left. At this time, the control module will change the output PWM duty cycle ( At this time, it is zero), and the LED driver module is controlled to turn off the LED light. When there is no one in the range of the LED light, it will automatically turn off the LED light to save power.

detailed description

Provide specific embodiment below in conjunction with accompanying drawing, further illustrate how the utility model is realized.

As shown in Figure 1, the utility model is an indoor LED lighting system controlled by smart phone Bluetooth. The system adopts a modular design and includes two parts: an LED control terminal and a remote control terminal. The LED control terminal mainly includes a control module, a Bluetooth module, an LED driver module, a light sensor module, an infrared sensor module, a power supply module, and a crystal oscillator module. Module, power module, crystal oscillator module are connected, and described LED driver module is also connected with LED light, realizes that control module receives adjustment signal through bluetooth module, controls to LED light; remote control end mainly includes control module, bluetooth module, switch button, The power module, the crystal oscillator module and the mobile phone bluetooth are characterized in that: the control module is connected with the bluetooth module, the switch button, the power supply module and the crystal oscillator module respectively, so as to realize the dimming signal sent by the switch button through the bluetooth module (or directly through the mobile phone client).

Through the smart phone with bluetooth function, you can start the related modes of LED lights indoors: general mode or constant light mode. The general mode is to adjust the switch and brightness of the light; the constant light mode is to set an ambient light intensity threshold through the mobile phone , when the external light intensity is greater than this value, the LED light will not light up. When the external light intensity is less than this value, the LED light will automatically turn on the supplementary light mode, so that the overall light intensity of the environment tends to the set threshold. Specifically, the mobile phone client sends out a dimming request. After receiving the signal, the Bluetooth module at the LED control end transmits it to the control module. adjustment.

The flow chart of the constant light mode adjustment program is shown in Figure 2. The adjustment method is as follows: when the light sensor module detects the ambient light intensity, it first compares it with the set light threshold to obtain the signal that needs to be adjusted. That is, when the data is greater (less than) the set value, the PWM duty cycle will be reduced (increased), and after a delay of 180ms (the sensor reflection time interval), the illumination information will be collected again and analyzed. If the data is still greater than (less than) the threshold, Repeat the above operations until the light intensity value reaches (or approaches) the set threshold value. Otherwise, it will delay for 5 seconds, and then detect the light intensity. When the data matches the set threshold value range, the system enters the bottom cycle operation state, otherwise it will Enter the dimming mode (this process is more important, if the system program does not have this part, the LED module will not emit light stably).

When the LED light is on, the light sensor will detect whether there is anyone in the environment in real time. When the infrared light source is not detected, it will notify the control module that the person has left. At this time, the control module will change the output PWM duty cycle ( At this time, it is zero), and the LED driver module is controlled to turn off the LED light. Realize the function of automatically turning off the LED light when there is no one in the irradiation range of the LED light, so as to save power.

When the system is separated from the mobile phone, all the functions controlled by the mobile phone can be realized through the switch buttons on the remote control terminal. When the button on the remote control terminal is touched, the control module will send a signal to the LED control terminal through the Bluetooth module. When the LED control terminal receives this signal, it will control the output voltage of the LED driver module by changing the output PWM duty cycle. LED lights or adjust the brightness.

Because the utility model adopts the above-mentioned structure, the measuring device has simple structure, low measurement cost and high degree of integration, and can conveniently use the mobile terminal to control the mode and parameters of the indoor LED lights, and at the same time, it can also be controlled wirelessly through the remote control terminal. LED lights. It has wide application value and market prospect.

In summary, the above specific embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. All based on the above-mentioned basic ideas and within the spirit and scope of the invention shall belong to the disclosure of the utility model. scope.
