The multifunctional mobile lighting lamp provided by the present invention comprises a housing 4, on which a transparent window 1 is installed through a fixing ring 2, and a sealing ring 13 is installed between the fixing ring 2, the housing 4 and the transparent window 1, and the transparent window 1 The inner side is provided with a parabolic reflector 3, and the focal point of the parabolic reflector 3 is installed with a lighting LED 12 and an LED 11 for indicating power shortage. The switch 7 is installed through the sealing sleeve 9, and the housing 4 is provided with a charging socket 10, which is used to plug in the external charger. The housing 4 is provided with a controller 5, as shown in Fig. 1, the controller 5 includes a lighting LED (D1) connected integrated circuit U1, the integrated circuit U1 is connected to the battery 6 (BT1) through the switch 7 (SW1), the battery 6 (BT1) is connected to the charging socket 10 (J1) through the protector FB, and the integrated circuit U1 is connected through the PNP tube (Q1) is connected to the LED 11 (D2～D5) for low power prompt.

The specific circuit structure is shown in Figure 2. Pin 1 of the integrated circuit U1 (model HRB-2012A) is grounded through resistors R1 and R2, and connected to the positive pole of battery BT1 through R7 and Q1. The positive pole is connected, the 4th pin of the integrated circuit U1 is connected to the positive pole of the battery through the switch SW1, the 5th pin of the integrated circuit U1 is grounded through the resistors R3 and R4, the 6th pin of the integrated circuit U1 is connected to the negative pole of the lighting LED, and the 7th pin of the integrated circuit U1 is grounded. Pin 8 of the integrated circuit U1 is connected to the base of Q1 through R5, the emitter of Q1 is connected to the positive pole of the battery BT1, the collector is connected to the under-power prompt LED through R6, and pin 1 of the integrated circuit U1 is connected through R7; the charging interface J1 Pin 2 is connected to the positive pole of battery BT1 through D6, pin 1 is grounded, the negative pole of battery BT1 is connected to pin 2 of the protector FB, pin 3 of the protector FB is grounded, pin 1 of the protector FB is connected to the negative pole of the battery, and the protector FB is BK5( A) Explosion-proof device.

When charging, after inserting the charger connected to the power supply through the charging socket J1, the current will charge the battery BT1 through D6 to prevent the battery from supplying power to the charger in reverse. The protector FB is connected in series in the charging and discharging circuit of the battery BT1 to monitor the charging and discharging current. At the same time, it is also connected in parallel to both ends of battery BT1 to monitor the voltage of battery BT1. When battery BT1 is normally charged or discharged, the current is about 500mA. When the voltage of BT1 is higher than 4.3V or lower than 2.8V, the charging or discharging circuit is cut off to prevent the battery BT1 from exploding due to excessive charging current or short circuit or burning due to excessive discharging current, or due to excessive or low voltage. damage, effectively protect the battery BT1, while ensuring that the rest of the circuit has a normal working voltage. Realize overcharge, overdischarge, short circuit and other protection functions.

C1 is connected to the positive and negative poles of the working voltage to filter out clutter interference. U1 is in the standby state for a long time, just press the light touch switch SW1 (7) to provide a high-potential trigger signal to the 4 pin of U1, and the 6 pin of U1 will output a low potential to drive the high-power LED 12 (D1) to work. Move the light touch switch SW1 (7) once to make the LED 12 (D1) work at full brightness or half brightness or flashing or off working status, and this cycle realizes the lighting of multi-level working status. Pin 1 of U1 is grounded through R1 and R2 to output a constant voltage source of 0.5V; pin 5 of U1 outputs a current source of 55uA and grounded through R3 and R4. When the voltage of battery BT1 is lower than the voltage of pin 5 of U1, U1 Pin 8 of the pin outputs a current of -2mA, and this current drives the base of Q1 (PNP tube) through R5 to make the emitter and collector of Q1 conduct, then the current passes through R6 to make the red LED 11 (D2～D5) glow, Make an under-power prompt, and at the same time, the current changes the potential of pin 1 of U1 through R7, so that the output current of pin 1 of U1 decreases. At this time, the driving current output by pin 6 of U1 (that is, the current for driving high-power lighting LED 12 (D1) ) is also reduced, so that the lighting enters the flashing state of emergency lighting, and a reminder of low battery power is issued, thereby realizing multi-function prompts such as multi-gear switching, low power indication, and emergency lighting flashing.
