The existing halogen lamp control circuit directly lights the halogen lamp after being powered on, so that the halogen lamp is impacted to a certain extent at the moment of being powered on, and the service life of the halogen lamp is shortened. The impact comprises thermal shock generated by the rapid temperature rise of the filament from room temperature to 2000 ℃ at the moment of the cold state power on of the halogen lamp, and the thermal shock easily fuses the filament, so that the light source fails. Since the filament heating process of the halogen lamp is also a resistance change process, the cold state resistance is usually only a fraction of the steady state, so the impact also comprises the load impact of the halogen lamp on the power supply due to the load resistance change at the moment when the halogen lamp is powered on in a cold state.
In view of the above problems, the present embodiment provides a halogen lamp control circuit, as shown in fig. 1, including a first rectifying module 100, a current limiting module 101, a second rectifying module 102, a charge-discharge module 103, and a switching module 104. The first rectifying module 100 is electrically connected to the current limiting module 101, the charge and discharge module 103, and the switching module 104, respectively. The current limiting module 101 is electrically connected to the switching module 104. The second rectifying module 102 is electrically connected to the charge and discharge module 103 and the switching module 104, respectively. The current limiting module 101 is also used for electrical connection with one end of the halogen LAMP. The second rectifying block 102 is also used for electrical connection with the other end of the halogen LAMP.
Specifically, when the halogen lamp control circuit is turned on the power supply 110, the first rectifying module 100 is configured to rectify the power supply voltage signal and output a first voltage signal to the current limiting module 101. The current limiting module 101 is configured to output a first current signal from small to large according to the first voltage signal, so that the halogen LAMP is gradually turned on according to the first current signal. The halogen LAMP control circuit provided by the embodiment of the application gradually lights the halogen LAMP through the first rectifying module 100 and the current limiting module 101 after the power supply 110 is switched on, so that the impact of the halogen LAMP in the moment of switching on the power supply 110 is avoided.
The second rectifying module 102 is configured to rectify the power voltage signal and output a second voltage signal to the charge/discharge module 103. The charging and discharging module 103 is configured to charge according to the second voltage signal, and when the voltage signal on the charging and discharging module 103 reaches the preset voltage signal, the switch module 104 is turned on, and the halogen LAMP is completely turned on. The halogen LAMP control circuit provided in the embodiment of the present application makes the switch module 104 delay on by using the charging process of the charging and discharging module 103 when gradually lighting the halogen LAMP, further, the time for completely lighting the halogen LAMP LAMP is delayed, the impact of the halogen LAMP LAMP at the moment of switching on the power supply is avoided, and the service life of the halogen LAMP LAMP is prolonged.
In summary, the halogen LAMP control circuit provided in the embodiment of the present application gradually lights the halogen LAMP after the power supply 110 is turned on, and then completely lights the halogen LAMP, the impact caused by the halogen LAMP LAMP at the moment of switching on the power supply 110 is avoided, and the service life of the halogen LAMP LAMP is prolonged.
The power supply 110 is a 220V ac power supply.
As shown in fig. 3, the first rectifying module 100 includes a first diode D1. The anode of the first diode D1 is electrically connected to the charge/discharge module 103 and the switch module 104, respectively, and the cathode of the first diode D1 is electrically connected to the current limiting module 101.
Specifically, after the halogen lamp control circuit is powered on, the first diode D1 is configured to rectify the power voltage to obtain a first voltage signal, and transmit the first voltage signal to the current limiting module 101.
As shown in fig. 3, the current limiting module 101 includes a first resistor R1. The first end of the first resistor R1 is electrically connected to the first rectifying module 100, the second end of the first resistor R1 is electrically connected to the switching module 104, and the second end of the first resistor R1 is also electrically connected to one end of the halogen LAMP. As can be seen from fig. 3, the first end of the first resistor R1 is electrically connected to the cathode of the first diode D1 in the first rectifying module 100.
Specifically, the first resistor R1 is configured to output a first current signal from small to large according to the first voltage signal output by the first diode D1 in the first rectifying module 100, so that the halogen LAMP is gradually turned on according to the first current signal.
Wherein the first resistor R1 is a negative thermistor. The first resistor R1 has a relatively large cold state resistance before the halogen lamp control circuit is turned on the power supply 110. The halogen lamp control circuit has a large surge current at the moment of turning on the power supply 110, and may damage the element, and the surge current can be suppressed by the first resistor R1. Under a sufficiently large current load, the resistance of the first resistor R1 is reduced to 1/(10 to 50) by self-heating, and the power consumed thereby is also reduced. Therefore, the present application limits the current flowing through the halogen LAMP by the first resistor R1, and gradually turns on the halogen LAMP from small to large.
When the first resistor R1 is used, the halogen lamp control circuit cannot be frequently turned on and off, and after the halogen lamp control circuit is turned off, the power supply 110 must be turned on again only after the first resistor R1 is completely restored from the high-temperature low-resistance state to the normal-temperature high-resistance state, so that the surge current suppression effect can be ensured.
As shown in fig. 3, the second rectifying module 102 includes a second resistor R2 and a second diode D2. The first end of the second resistor R2 is electrically connected to the other end of the halogen LAMP, the second end of the second resistor R2 is electrically connected to the anode of the second diode D2, and the cathode of the second diode D2 is electrically connected to the charge/discharge module 103 and the switch module 104, respectively.
Specifically, after the second resistor R2 divides the power supply voltage, the second diode D2 rectifies the power supply voltage to obtain a second voltage signal, and transmits the second voltage signal to the charge-discharge module 103.
Illustratively, the second resistor R2 is a cement resistor.
As shown in fig. 3, the charge and discharge module 103 includes a first capacitor C1. The positive electrode of the first capacitor C1 is electrically connected to the second rectifying module 102 and the switching module 104, and the negative electrode of the first capacitor C1 is electrically connected to the first rectifying module 100 and the switching module 104. As can be seen from fig. 3, the positive electrode of the first capacitor C1 is electrically connected to the cathode of the second diode D2 in the second rectifying module 102 and the switching module 104, respectively. The negative electrode of the first capacitor C1 is electrically connected to the anode of the first diode D1 in the first rectifying module 100 and the switching module 104, respectively.
Specifically, the first capacitor C1 is configured to charge according to the second voltage signal, and when the voltage signal on the first capacitor C1 reaches the preset voltage signal, the switch module 104 is turned on, and the halogen LAMP is completely turned on. The process that this application utilized first electric capacity C1 to charge makes switch module 104 delay turn on, and then has delayed the time that halogen LAMP LAMP was lighted completely to avoid halogen LAMP LAMP to receive in the switch-on power instant impact, and then prolonged halogen LAMP LAMP's life.
As shown in fig. 3, the switch module 104 includes a relay K1 and a third diode D3. The first pin 1 of the relay K1 is electrically connected with the cathode of the third diode D3, the second rectifying module 102 and the charging and discharging module 103, respectively, the second pin 2 of the relay K1 is electrically connected with the anode of the third diode D3, the seventh pin 7 of the relay K1, the eighth pin 8 of the relay K1, the charging and discharging module 103 and the first rectifying module 100, respectively, the fifth pin 5 of the relay K1 is electrically connected with the third pin 3 of the relay K1, the fourth pin 4 of the relay K1, the sixth pin 6 of the relay K1 and the current limiting module 101, respectively, and the fifth pin 5 of the relay K1 is also used for being electrically connected with one end of the halogen LAMP.

Specifically, the first capacitor C1 is charged according to the second voltage signal, when the voltage signal on the first capacitor C1 reaches the preset voltage signal, the preset voltage signal acts on the first pin 1 of the relay K1, so that the relay K1 is attracted, the fifth pin 5 of the relay K1 and the seventh pin 7 of the relay K1 are connected, the sixth pin 6 of the relay K1 and the eighth pin 8 of the relay K1 are connected, and the LAMP access power supply loop of the halogen LAMP is completely lighted.
The third diode D3 functions as a freewheel. When the relay K1 is powered off, a self-induced electromotive force is generated at two ends of the relay K1, and the self-induced electromotive force is damaged. The third diode D3 is connected in anti-parallel to the two ends of the relay K1, so as to provide a discharging current loop (freewheeling) for the self-induced electromotive force, thereby playing a role in protection. When the relay K1 is powered off, the residual energy is released in a proper way, and if the third diode D3 is not provided, the residual energy is released in a spark form, so that the device is damaged.
