Description

Technical Field

[0001] The invention relates to an intelligent LED lighting control panel and belongs to the field of lamps. Background Art

[0002] Smart LED lighting refers to the integration of LED with sensing technology and control technology. It not only saves energy and reduces emissions and has a long lifespan, but also can use smart terminals to remotely control smart LED lighting fixtures wirelessly. For example, remote control can be used to turn lights on and off, and to adjust the brightness and color of LED lighting. Remote control provides people with great convenience and interactivity, so the market prospects for smart LED lighting are very huge.

[0003] In the prior art, smart LED lighting fixtures are connected to smart terminals via Bluetooth or Wi-Fi. However, in actual applications, smart LED lighting fixtures may need to change the way they are connected to smart terminals according to the on-site environment. For example, some environments only support Wi-Fi access, in which case you can only use Wi-Fi to access smart LED fixtures, or some environments only support Bluetooth access, in which case you can only use Bluetooth to access smart LED fixtures. This undoubtedly brings some inconvenience to the production, sales or use of smart LED lighting fixtures; or in some situations where both Bluetooth or Wi-Fi access methods can be supported at the same time but the control requirements are relatively high, the Bluetooth access method weakens the signal due to the influence of distance and obstacles, resulting in control failure. Although smart LED lighting fixtures accessed via Wi-Fi have high control accuracy, they are expensive and not easy to popularize. Summary of the invention

[0013] Correspondingly, the touch switch module is further used to receive a wake-up enable signal sent by the main control module, and send a reset signal generated according to the wake-up enable signal to the main control module.

[0014] Furthermore, the control board also includes a boost module, which is electrically connected to the LED driving module and is used to boost the input voltage to a preset voltage value.

[0015] Wherein, the boost module is a DCDC boost module.

[0016] Wherein, a plurality of groups of LED light strips in the LED light circuit module are connected in parallel, and the LED lights in each group of LED light strips are connected in series.

[0021] Furthermore, the main control module, touch switch module, infrared sensor module and LED driving module are all arranged in the center of the disk, and the LED light path module is arranged on the outer circle of the outer edge of the disk.

[0022] The beneficial effects of the present invention are:

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, actual examples are given here and further explained with reference to the accompanying drawings.

[0036] See also Figure 1 , an embodiment of the present invention provides an intelligent LED lighting control board, including a main control module 11, a touch switch module 12, an infrared sensing module 13, an LED light circuit module 14 and an LED driving module 15;

[0037] The main control module 11 is electrically connected to the touch switch module 12 and the infrared sensing module 13, respectively, and is used to receive the light-on or light-off command sent by the touch switch module 12, and trigger the infrared sensing module 13 according to the light-on or light-off command; the main control module 11 is integrated with WIFI, Bluetooth, zigbee and other transmission methods;

[0038] The touch switch module 12 is used to send the received light on or light off command to the main control module 11;

[0039] The infrared sensing module 13 is used to perform corresponding operations on the LED light path module 14 through infrared sensing after being triggered by the main control module 11;

[0040] The LED driving module 15 is electrically connected to the main control module 11 and the LED light path module 14 respectively, and is used to convert the voltage of the input power supply under the control of the main control module 11, and provide the converted voltage to the LED light path module 14;

[0041] The LED light circuit module 14 is used to realize LED lighting under the driving of the LED driving module 15 and the sensing of the infrared sensing module 13 .

[0042] Furthermore, the control board also includes a reset circuit, which is electrically connected to the main control module and is used to restore the circuit to an initial state under the control of the main control module.

[0043] Furthermore, the main control module 11 is also used to receive a light-off instruction sent by the touch switch module 12 to maintain low power consumption mode operation; receive a light-on instruction sent by the touch switch module 12, and send a wake-up enable signal to the touch switch module 12; and receive a reset signal sent by the touch switch module 12 to maintain normal mode operation;

[0044] Correspondingly, the touch switch module 12 is also used to receive the wake-up enable signal sent by the main control module 11, generate a reset signal according to the wake-up enable signal, and send the reset signal to the main control module 11, so that the main control module 11 maintains normal mode operation.

[0045] For example, when the main control module 11 maintains low power consumption mode, the current of the main control module 11 is about 5 microamperes. Adding the current of other modules, the total current of the control board can be less than about 8 milliamperes, which greatly saves power resources.

[0046] Figure 2 is a circuit diagram of a main control module provided by an embodiment of the present invention, Figure 2 In the figure, the main control module is the ESP8266-12S chip, BR1 and BC1 form a power-on reset module, the chip pin 3 is connected in series with BR2 to VCC to make the chip effective, the chip pin 4 is the DCDC boost module power enable control pin PWEN, the 5th pin is the touch switch detection pin touch pin, the 6th pin is the infrared sensor switch detection pin GY pin, the 7th and 10th pins are the serial port pins for communicating with the LED constant current driver chip, the 11th and 12th pins are the chip configuration pins for downloading and starting, the 13th pin is the infrared sensor module power control pin, the 14th pin is the touch switch to wake up the main control chip from sleep and enable the control pin, the 15th and 16th pins are the serial port pins for program downloading.

[0047] Figure 3 is a circuit diagram of a touch switch module provided by an embodiment of the present invention, Figure 3 TTP232-CA6 is a capacitive touch chip, BP2 is a metal touch sheet, and the 1-pin TOUCH port outputs a high level to indicate no touch. When the metal touch sheet is touched by hand, the 1-pin outputs a low level, which can be detected by the main control module to see if the switch is pressed. 74HC1G32 is an "AND" operation chip, which is used to enable the touch switch module to wake up the main control module from sleep. IMP811 is used to connect the chip reset port and reset signal.

[0048] When the touch switch module 12 receives the light-on instruction, the touch switch module 12 sends the generated reset signal to the reset pin of the main control module 11 through the logic interaction with the main control module, wakes up the main control module 11, and makes the main control module 11 keep running in normal mode. For example, when the touch switch module 12 receives the light-on instruction, the TOUCH pin changes from high level to low level, so that the output of the "AND" logic chip 74HC1G32 changes from high level to low level, generating a reset signal, and this reset signal is sent to the reset pin of the main control module 11 through the reset chip IMP811, thereby waking up the main control module 11.

The compared signal is sent to the main control module.

Pins 18 and 19 are used to receive the serial port data for light color adjustment sent from the main control module.

[0051] Furthermore, the embodiment of the present invention also includes: a boost module, electrically connected to the LED driving module, for boosting the input voltage to a preset voltage value and reserving a specified voltage for the LED driving module, thereby ensuring the stability of the output constant current.

[0052] The boost module in the embodiment of the present invention is specifically a DCDC boost module, and each group of constant current sources is connected in series with two LED chips. Figure 6 The DCDC boost module provides a DCDC boost module that increases the voltage of a 3.7V lithium battery to 7.2V, with a boost efficiency of 95%, and then reserves more than 1V of voltage to supply the LED drive module, thereby ensuring the output constant current stability.

From left to right, the LED light circuit module is red, blue, green, and white. The 7.4 volt voltage output is connected to four parallel red, blue, green, and white light strips. Take the blue LED light strip as an example. Since the forward conduction voltage of the blue LED light strip is about 3.2 volts, two LEDs are connected in series, and the remaining 7.4-3.2-3.2=1 volt is sent to the output port of the LED driver module. Since the rated current of the LED used is 20 mA, and the constant current output of the LED driver module is 300 mA, 10 groups of blue LEDs are connected in parallel, each group consisting of two blue LEDs connected in series, and the LED light strips of other colors are arranged in the same way.

[0058] Furthermore, the control panel adopts a disk shape, the main control module, the touch switch module, the infrared sensing module and the LED driving module are all arranged in the center of the disk, and the LED light path module is arranged in the outer ring of the outer edge of the disk, which has a higher heat dissipation effect and is convenient for the manufacture of disk-type lamps.
