[0028] In this embodiment, it also includes a positive input terminal, a positive output terminal, a negative input terminal and a negative output terminal, and the positive input terminal and the negative output terminal are connected to a battery; an electric object is connected between the positive output terminal and the negative input terminal; wherein the other end of the photoresistor RL1, the other end of the resistor R2, and the drain of the N-MOS tube Q4 are all connected to the positive input terminal; the source of the N-MOS tube Q4 is connected to the positive output terminal; the other end of the variable resistor VR1, the source of the N-MOS tube Q1, the source of the N-MOS tube Q2, and the source of the N-MOS tube Q3 are all connected between the negative input terminal and the negative output terminal.
[0029] In this embodiment, a resistor R3, a resistor R4 and a variable resistor VR2 are also included; one end of the resistor R3 is connected between the capacitor C1 and the gate of the N-MOS tube Q3; the gate of the N-MOS tube Q1, the drain of the N-MOS tube Q2, and one end of the capacitor C2 are commonly connected to one end of the resistor R4; the other end of the resistor R3 and the other end of the resistor R4 are both connected to one end of the variable resistor VR2, and the other end of the variable resistor VR2 is connected between the positive input terminal and the drain of the N-MOS tube Q4; a resistor R5 is also included; one end of the resistor R5, one end of the capacitor C2, one end of the resistor R6, and the drain of the N-MOS tube Q3 are connected to each other; the other end of the resistor R5 is connected between the positive input terminal and the drain of the N-MOS tube Q4.
[0030] The principle of the integrated circuit of the aviation obstruction light power switch of this embodiment is as follows:
[0031] The N-MOS tube Q4 is used as the power switch of the aviation obstruction light (essentially an LED light). Since the gate (control electrode) of the N-MOS tube Q4 is connected to the drain of the N-MOS tube Q3, the N-MOS tube Q4 is also the driving output of the flasher. During the driving process of the flasher, when the gate (control electrode) level of the capacitor C2 and the N-MOS tube Q1 increases, the N-MOS tube Q1 is turned on, the drain of the N-MOS tube Q1 is at a low level, and the capacitor C1 pulls down the gate (control electrode) level of the N-MOS tube Q3, and the N-MOS tube Q3 is turned off, and the drain of the N-MOS tube Q3 is at a high level. At the same time, the capacitor C1 is charged through the resistor R3. When the voltage of the capacitor C1 rises to a high level, the N-MOS tube Q3 is turned on, and the capacitor C2 turns off the N-MOS tube Q1. Then, the capacitor C2 is charged through the resistor R4, and the gate (control electrode) voltage of the capacitor C2 and the N-MOS tube Q1 increases again. In this way, the N-MOS tube Q1 and the N-MOS tube Q3 are turned on and off in turn. The drain level of N-MOS tube Q3 is transmitted to N-MOS tube Q4 through resistor R6 to control the on and off of aviation obstruction lights. Since the time constant determines the oscillation period. Therefore, adjusting the variable resistor VR2 can change the flash frequency. Changing the ratio of capacitor C1 to capacitor C2 or the duty ratio of resistor R3 to resistor R4 can change the duty ratio of the light on and off. In the process of realizing the photosensitive switch, the photoresistor RL1 is used as a sensor to measure the daybreak and darkness. At night, the resistance of the photoresistor RL1 increases, the voltage division on the variable resistor VR1 decreases, and the N-MOS tube Q2 is cut off, which does not affect the normal oscillation of the N-MOS tube Q1 and the N-MOS tube Q3. After dawn, the resistance of the photoresistor RL1 decreases, the voltage division on the variable resistor VR1 increases, and the N-MOS tube Q2 is turned on, prompting the N-MOS tube Q1 to be turned off, and the N-MOS tube Q3 is turned on, and no longer oscillates. Resistor R6 obtains a low level, and the N-MOS tube Q4 is cut off to turn off the power supply of the aviation obstruction light. By adjusting the resistance value of the variable resistor VR1, the reversal point of the brightness change can be changed.
[0032] If the coefficient of the photoresistor RL1 is opposite, the drain of the N-MOS tube Q2 can be connected to the gate (control electrode) of the N-MOS tube Q3. Figure 1 It can be seen that the advantages of this hybrid circuit are: 1. N-MOS tube Q4 is both the power supply of the lamp and the driver of the flash. 2. N-MOS tube Q1 and N-MOS tube Q3 are components of the oscillation circuit and the amplification and shaping circuit of the photosensitive circuit, making the light control reversal point clearer. 3. All NMOS field effect tubes are used, combined with high-resistance resistors, with extremely small current and extremely low power consumption.
[0033] It should be emphasized that Figure 1 Circuit components that are not explained or described in detail, such as batteries, power-consuming aviation obstruction lights, etc., belong to the prior art themselves and will not be described in detail here.
[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
