[0028] Figure 1 This is a schematic diagram of the electronic circuit for a lamp base control circuit that is compatible with various TV remote control switches. Detailed Implementation
[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.
[0030] like Figure 1 As shown, a lamp base control circuit adapted to various TV remote control switches includes a power supply circuit, a relay, an infrared receiver module, a control circuit, and a lighting lamp LAMP1, wherein:
[0031] The functions and connections of each circuit module are as follows:
[0032] The power supply circuit is connected to the relay, the infrared receiving module, and the control circuit respectively.
[0033] The infrared receiving module is used to receive external key commands and send corresponding control signals to control the control circuit according to the commands. The infrared receiving module U1 adopts KS1837.
[0034] The control circuit is equipped with multiple transistors. The control circuit receives the control signal from the infrared module and controls the multiple transistors to turn on and off.

[0036] The relay is connected to the lighting lamp LAMP1 and is used to control the switching on and off of the lighting lamp LAMP1.
[0037] Specifically, the power supply circuit includes a step-down circuit, a bridge rectifier circuit, a first filter circuit, a voltage divider circuit, and a voltage regulator circuit connected in sequence.
[0038] The step-down circuit includes capacitor C2, one end of which is connected to 220V AC mains, and the other end is connected to a bridge rectifier circuit. A discharge resistor R1 is connected in parallel with capacitor C2. The bridge rectifier circuit consists of diodes D1, D2, D3, and D4. The first filter circuit includes parallel capacitors C3 and C4, one end of which is connected to the bridge rectifier circuit, and the other end is connected to relay RELAY 1 for filtering, thus powering the relay. The voltage regulator circuit includes diodes ZD1 and C5 connected in parallel for voltage regulation, providing 5.1VDC power to the remote control receiver and control circuit. The voltage regulator circuit is connected to the bridge rectifier circuit through resistor R6, and is also connected in parallel across the infrared receiver module. Resistor R2 is also connected in parallel across the voltage regulator circuit. Resistors R2 and R6 form a voltage divider circuit to ensure that the reverse breakdown current of diode ZD1 is less than its rated value.
[0039] When the power supply circuit is working, the 220V mains power is stepped down by the step-down circuit, then rectified by the bridge rectifier circuit and connected to the relay to provide power to the relay;
[0040] The 220V AC mains power is stepped down by a step-down circuit, then rectified by a bridge rectifier circuit, filtered by a first filter circuit, divided by a voltage divider circuit, and regulated by a voltage regulator circuit to obtain a 5.1V DC voltage, which powers the infrared receiver module and control circuit.
[0041] Specifically, the control circuit includes a coupling circuit, a second filter circuit, a third filter circuit, a fourth filter circuit, a fifth filter circuit, a transistor Q1, a transistor Q2, a transistor Q3, and a transistor Q4;
[0042] The coupling circuit is connected to the output port of the infrared receiving module. The coupling circuit, the second filter circuit, transistor Q1, the third filter circuit, transistor Q2, the fourth filter circuit, transistor Q4, the fifth filter circuit, and transistor Q3 are connected sequentially via electrical signals.
[0043] The output of transistor Q3 is connected to relay RELAY 1 via LED1; the coupling circuit includes a resistor R3 and a capacitor C6 connected in series. The output of the infrared receiving module is connected to resistor R3, and the other end of capacitor C6 is connected to the base of transistor Q1; the second filter circuit includes capacitors C7 and C8, which are used to filter and absorb narrow-amplitude pulses before inputting the output signal to the base of transistor Q1; the third filter circuit includes a capacitor C9 and a resistor R9 connected in parallel. The collector of transistor Q1, diode D5, resistor R8, and the third filter circuit are connected to the base of transistor Q2; the fourth filter circuit includes a capacitor C9 connected in parallel... The transistor Q2 has a capacitor C10 and a resistor R10 connected in parallel between the emitter and collector of the transistor Q2. The collector of the transistor Q2 is connected to the base of the transistor Q4. The base of the transistor Q4 is connected to the collector of the transistor Q3, and the collector of the transistor Q4 is also connected to the base of the transistor Q3. The fifth filter circuit includes a capacitor C11 and a capacitor C12. The capacitor C11 is connected between the base and emitter of the transistor Q4, and the capacitor C12 is connected between the base and emitter of the transistor Q3.
[0044] When U1 receives the signal from the infrared remote control, it outputs a series of continuously looping pulse group waveforms with varying pulse widths. These pulse group waveforms are coupled to the base of transistor Q1 via R3 and C6, and then output from the collector of Q1. Since some narrow-amplitude pulses are filtered and absorbed by capacitors C7 and C8 of the second filter circuit before being input to the base of Q1, the narrow-amplitude signal output by the infrared receiver module due to interference from other signals can be resisted. At the same time, the second filter circuit C7 and C8 can also filter out grid interference signals under normal circumstances from entering the base of Q1, ensuring that this invention has stable anti-interference performance.
[0045] The process and circuit principle of turning off the lights using any TV remote control are as follows:
[0046] A short press of the infrared remote control button, such as a brief (less than 1 second) click followed immediately by releasing the "volume +" button (equivalent to a light switch button), sends a control signal via infrared. The infrared receiving module of this invention receives the control signal from the remote control and outputs a pulse group waveform from the collector of Q1. This waveform then passes through resistor R7 to the base of transistor Q4, causing Q4 to conduct. This conducts Q3, which in turn conducts, LED1, and consequently, relay RELAY 1, turning off the light LAMP1.
[0047] During this process, although D5 in series with R8 also transmits the pulse group signal of the collector of Q1, the charging and filtering through capacitor C9 and R9 in the third filter circuit prevents the base of Q2 from obtaining sufficient conduction voltage under the condition of "clicking once and then releasing the remote control for a short time". Therefore, Q2 does not conduct, and has no effect on the conduction state of Q4 and Q3.
[0048] In the fourth filter circuit, capacitor C10 and resistor R10 absorb power grid interference, ensuring that transistors Q4 and Q3 are not easily turned on by power grid interference. The connection between transistors Q4 and Q3 is similar to that of a unidirectional thyristor, exhibiting a self-locking conduction state. This means that once Q4 turns on, causing Q3 to also turn on, the transistors will remain on even if the pulse group signal output from the collector of Q1 is removed.
[0049] The fifth filter circuit, C11 and C12, is used to improve the anti-interference capability of transistors Q4 and Q3 through filtering.
[0050] The process and circuit principle of turning on the lights using any TV remote control are as follows:
[0051] Press and hold the button on the infrared remote control for more than 1 second. The pulse group waveform output from the collector of Q1 will pass through resistor R7 and enter the base of transistor Q4, causing Q4 to conduct. This will turn on Q3, and thus relay RELAY 1 will conduct, turning off lamp LAMP1.
[0052] If Q4 was already on and in the off state, the lights will remain off for 1 second until the following happens after 1 second:
[0053] Since D5 in series with R8 also transmits the pulse group signal of the collector of Q1, after being charged and filtered by capacitor C9 and R9 of the third filter, the voltage continues to rise, eventually enabling the base of Q2 to obtain sufficient conduction voltage and base current, thus making the collector and emitter of Q2 conduct. At this time, the base and emitter of Q4 are short-circuited, causing Q4 to exit the conduction state, Q3 also becomes cut off, LED1 goes out, the relay is de-energized and pops open, and the lighting lamp LAMP1 lights up.
[0054] This utility model is equipped with an infrared receiving module. Through the cooperation of the infrared receiving module, control circuit and relay, home lighting fixtures can be remotely controlled by any TV remote control, greatly improving the convenience of using home lighting fixtures. At the same time, this utility model can be used with any model of TV remote control, which is conducive to market promotion.
