Description

Intelligent lamp and standby control method thereof, intelligent lighting system

Technical field

The present invention relates to the field of intelligent lighting, and in particular to an intelligent lamp, a standby control method thereof, and an intelligent lighting system.

Background technique

Smart lamps currently on the market all have standby and standby wake-up functions. Users can control the lamp with a mobile phone APP or remote control to realize the standby function of the lamp. After standby, the lamp turns off. At the necessary time, the user can use the mobile phone APP or remote control to wake up the lamp from standby.

However, during use, users often find that after some lamps are put on standby at night, even if they should be in a state where the power is turned off and the lights are off, the light-emitting area of the lamps will still flash or be slightly bright, and this The luminescence phenomenon obviously does not fall within the functional scope defined at the beginning of product design. The luminescence after standby at night will also greatly affect the user's experience. In addition, since any lamp that emits light indicates that there is current flowing through the luminous area, therefore, the luminescence after standby will also greatly affect the user experience. The phenomenon of luminescence also means that there is uncontrolled current in the lamp, which can easily cause safety hazards.

Please see Figure 1. Figure 1 is a circuit diagram of a smart LED lamp commonly used in the prior art. As shown in the figure, L is the live wire of the lamp, N is the neutral line of the lamp, and the microcontroller outputs the STB signal to control the standby control circuit. After receiving the STB standby signal, the standby control circuit turns off the live wire of the lamp in the driver. After the live wire of the lamp is turned off, the back-end circuit no longer works.

With the above solution, when users install lamps in fixed locations indoors, they often fail to confirm the corresponding connection methods between the live wire L and neutral wire N in the room and the live wire L and neutral wire N marked on the lamp, causing the problem. The indoor live wire L is connected to the position marked N on the lamp, and the indoor neutral wire N is connected to the position marked L on the lamp (ie reverse connection):

If the user uses a mobile phone APP or remote control to control the lamp to realize the standby function of the lamp, the standby control circuit actually disconnects the neutral line N of the lamp, the live wire L of the lamp connected to the indoor lamp is not disconnected, and the LED lamp beads pass through the lamp panel and lamp shell. The capacitance coupled to the ground is large, and the induced current flowing through the LED lamp bead is large at this time. Due to the existence of the induced current, the constant current driving LED current will be slightly bright or flashing. At night, after the lamp is put on standby, some lamps will see the light-emitting area appear faintly bright or flashing.

The current solution to this problem is generally to add a standby control circuit on the basis of the above technical solution. The structural diagram is shown in Figure 2. This greatly increases the cost of materials and takes up more packaging space. PCB area.

Therefore, finding a method to eliminate the problem of faint brightness and flashing after the lamp is on standby is an urgent problem that needs to be solved by those skilled in the art.

At the same time, it is ensured that the fuse of the driving power supply of the smart lamp is connected to the live wire of the lamp, further improving the safety of the smart lamp.

On the basis of the first embodiment, the detection circuit 100 is further limited to obtain the second embodiment. The structural diagram of the voltage detection circuit 100 is shown in Figure 4, including the detection circuit 100, a microcontroller 200, a standby The control circuit 300, the rectifier circuit 400, the filter circuit 500 and the lamp live wire and the lamp neutral wire between the rectifier circuit 400 and the filter circuit 500;

The microcontroller 200 is connected to the standby control circuit 300, and the standby control circuit 300 controls the on and off of the live wire of the lamp;

The difference between this specific implementation mode and the above-mentioned specific implementation mode is that the specific structure of the voltage detection circuit 100 is given in this specific implementation mode. The other structures are the same as the above-mentioned specific implementation mode and will not be described again here.

Combined with Figure 4, V2 is the voltage obtained by V1 through the first resistor R3. It should be noted that the following PWM signal is the signal sent by the detection circuit 100 to the microcontroller 200. The U2 chip (i.e., the zero-crossing There is a threshold voltage V inside the detection chip). When V2>V, the VCC pin voltage at U2 charges the driving capacitor C3 to V3 through the Reset pin. The light-emitting diode inside the optocoupler chip U3 does not receive a signal. The transistor is in the cut-off state, so that the output PWM signal is high level and the voltage is VDD. When the voltage V2<V, the energy V3 stored in the C3 capacitor is released through the light-emitting diode inside the optocoupler chip U3, the Reset pin and the GND pin at U2 to the negative electrode of C3. The light-emitting diode inside the optocoupler chip U3 receives a signal and drives the transistor inside the optocoupler chip U3 to conduct, causing the output PWM signal to be low level.

The working flow of the voltage detection circuit 100 in this specific embodiment is described in detail below:

1) When the smart lamp is normally lit, regardless of whether the neutral line of the lamp is reversely connected or not, the situation in the circuit is the same. Specifically, due to the input potential alternating current, when the V1 signal voltage is at a higher value, the first The voltage V2 of the resistor R3 needs the Zener diode ZD1 to be stable within the working power supply voltage range of U2, V2>V, and the PWM signal is high level; when the V1 signal voltage drops to near zero, the voltage V2 passing through the first resistor R3< V, the PWM signal is low level. The V1 signal is a 50HZ voltage waveform. The voltage changes from high to near zero every 20ms. The PWM outputs high and low pulse signals and generates a low-level pulse signal every 20ms. When the microcontroller 200 receives the above signal, it always causes the standby control circuit 300 to conduct the live wire of the lamp to keep the smart lamp emitting light normally.

2) When the smart lamp receives the standby signal, and the neutral line of the lamp and the live wire of the lamp are correctly connected to the external circuit, the V1 signal voltage is always near zero, so that the voltage V2 through the first resistor R3 <V, C3 stores After the energy is released, the PWM signal outputs a low pulse voltage, and after the energy stored in C3 is released, the PWM output is always a high-level signal. The microcontroller 200 that has always detected a high-level signal can determine that the neutral line of the lamp and the live line of the lamp are correctly connected to the external circuit. At this time, the smart lamp is in a normal standby state.

3) When the smart lamp receives the standby signal, and the neutral line of the lamp and the live wire of the lamp are reversely connected to the external circuit, when the V1 signal voltage is at a higher value, the voltage V2 passing through the first resistor R3 needs to be stabilized. When diode ZD1 stabilizes within the working power supply voltage range of U2, V2>V, the PWM signal is high level; when the V1 signal voltage drops to near zero, the voltage through the first resistor R3 is V2<V, and the PWM signal is low level. . The V1 signal is a 50HZ voltage waveform. The voltage changes from high to near zero every 20ms. The PWM outputs high and low pulse signals and generates a low-level pulse signal every 20ms. That is to say, after receiving the standby signal, the microcontroller 200 can still receive a low-level pulse signal with a fixed frequency, which means that the zero line of the lamp and the live line of the lamp are connected to the external circuit at this time. If the connection is reversed, the user needs to be reminded to reconnect the live wire and the neutral wire of the lamp. The microcontroller 200 can drive the standby control circuit 300 so that the light-emitting unit emits light according to the preset alarm mode (such as controlling The light-emitting unit performs a light-off cycle), and can also send out alarm information through the alarm device mentioned above.

The present invention also provides a standby control method for smart lamps. The flow diagram of one specific implementation mode is shown in Figure 5, which is called the third specific implementation mode. The smart lamps are as described in any one of the above.

Step S103: When the micro-control module receives the reverse connection signal, the micro-control module controls the standby control circuit to cause the smart lamp to emit light according to a preset alarm mode.

When the intelligent lamp receives a standby signal, the detection circuit determines the status of the intelligent lamp. The voltage signal of the positive pole of the rectifier bridge; when the voltage signal is a high or low pulse signal, the detection circuit sends a reverse connection signal to the micro control module; when the micro control module receives the reverse connection signal, the The microcontrol module controls the standby control circuit so that the smart lamp emits light according to a preset alarm mode. By adding the detection circuit to the smart lamp, the present invention can confirm whether the neutral line of the lamp and the live wire of the lamp are reversely connected through the rectifier bridge after the smart lamp receives the standby command. When the reverse connection is confirmed, the micro-controller The controller can control the standby control circuit to make the lamp light up according to the preset alarm mode, reminding the user that the neutral line of the smart lamp and the live wire of the lamp need to be connected reversely, and the direction of the plug needs to be changed to reconnect the lamp. The neutral line and the live wire of the lamp avoid the reverse connection between the neutral line of the lamp and the live wire of the lamp, so that the standby control circuit clearly corresponds to the live wire of the lamp of the external circuit, that is, the external current must first be controlled on and off by the standby control circuit. The area then reaches the light-emitting unit of the smart lamp, so that the light-emitting unit does not have induction power after entering standby mode, which fundamentally avoids the problem that the light-emitting unit will still emit light after entering standby mode, and at the same time ensures that the The fuse of the driving power supply of the smart lamp is connected to the live wire of the lamp, further improving the safety of the smart lamp.
