The second LED light group 722 emits light upward around the mounting post 740, so that light can be emitted evenly in all directions of the lampshade 730.

[0045] The mounting column 740 can be made of aluminum alloy or steel material. The mounting column 740 is hollow. The energy storage module 500 can be placed in the mounting column 740 to save space, making the bulb body more compact and smaller in size, and can dissipate heat for the second circuit board 850.

[0046] Specifically, the first LED light group 721 may include multiple warm white lamp beads and multiple cold white lamp beads, and the multiple warm white lamp beads and the multiple cold white lamp beads are driven by different switch tubes respectively to adjust different color temperatures, and the second LED light group 722 may include LED lamp beads of multiple different colors.

[0048] In some embodiments of the present invention, Figure 1 , 2 As shown in FIG. 3 , a control button 820 may also be provided on the connection socket 710 . The control button 820 may be connected to the lighting control module 600 . The user may press the control button 820 to execute the control command to control the brightness and color of the lighting group 720 .

[0049] In some embodiments of the present invention, Figure 2 , 3As shown, the connection socket 710 can also be provided with a wireless receiving component 830, which can be a Bluetooth chip, an infrared receiver, a WiFi chip, etc. The user can send wireless control instructions through the corresponding remote control, and the wireless receiving component 830 is connected to the lighting control module 600. The wireless receiving component 830 receives the control instructions to control the brightness and color of the lighting group 720.

[0050] This design adopts multi-core processing. The charging management module 300 determines whether there is AC power input and the switch status of the wall switch 900, and coordinates the charging of the energy storage module 500. The lighting control module 600 determines the light intensity feedback signal output by the control command output by the charging management module 300 and controls the control commands input by components such as the timing switch, the wireless receiving component 830 and the control button 820, or controls the operation of the charging indicator and the power indicator, and then controls the operation of the lighting source 700 according to the judgment result. Different processing chips share different processing logics, reducing the processing load and making the control more orderly and reasonable.

[0051] In some embodiments of the present invention, Figure 4 As shown, the emergency multifunctional lighting device also includes a resistor R13 and a diode D6, one end of the resistor R13 is respectively connected to the plug-in charging port 200 and the output end of the power modulation module 100, the other end of the resistor R13 is connected to the positive electrode of the diode D6, and the negative electrode of the diode D6 is respectively connected to the charging regulation end and the energy storage module 500.

[0052] The diode D6 isolates the output end of the plug-in charging port 200 and the power modulation module 100 from the charging regulation end and the energy storage module 500. The voltage output by the energy storage module 500 will not affect the output end of the plug-in charging port 200 and the power modulation module 100, and thus will not affect the judgment of the power sampling end on whether there is an AC power input. The resistor R13 limits the current of the charging voltage, so that the charging voltage can stably charge the energy storage module 500.

[0053] In addition, the charging regulation end is connected to the energy storage module 500, and the charging management module 300 has a built-in switch element, one end of the switch element is connected to the charging regulation end, and the other end of the switch element is grounded. The charging management module 300 controls the on and off of the switch element, thereby controlling the charging current and charging voltage provided to the energy storage module 500.

[0054] In some embodiments of the present invention, Figure 4As shown, the emergency multifunctional lighting device also includes a signal integration module 400, the first input end of the signal integration module 400 is respectively connected to one end of the resistor R13, the plug-in charging port 200 and the output end of the power modulation module 100, the second input end of the signal integration module 400 is connected to the lighting control end, and the output end of the signal integration module 400 is connected to the lighting controlled end.

[0055] The first input end of the signal integration module 400 can be used as a power sampling end to detect whether there is AC power input, and after the switch sampling end obtains the on-off status information of the wall-controlled switch 900, the lighting control end of the charging management module 300 outputs a control instruction. The signal integration module 400 integrates the two signals and then outputs them to the lighting control module 600, which controls the lighting light source 700.

[0056] Specifically, the signal integration module 400 includes a resistor R14, a resistor R15, a resistor R16, a resistor R17 and a semiconductor switch tube Q6, one end of the resistor R14 is respectively connected to one end of the resistor R13, the plug-in charging port 200 and the output end of the power modulation module 100, the other end of the resistor R14 is respectively connected to one end of the resistor R15 and the controlled end of the switch tube Q6, one end of the resistor R16 is connected to the lighting control end, the input end of the switch tube Q6 is respectively connected to the other end of the resistor R16, one end of the resistor R17 and the lighting controlled end, and the output end of the switch tube Q6 and the other end of the resistor R17 are both grounded.

[0057] The switch tube Q6 can be an N-type transistor or a MOS tube. The resistors R14 and R15 divide the input voltage of the power supply, and judge whether there is an AC power input from the input voltage. When there is an AC power input, the controlled end of the switch tube Q6 is high, the switch tube Q6 is turned on, and the lighting controlled end receives a low level. When there is no AC power input, the controlled end of the switch tube Q6 is low, the switch tube Q6 is disconnected, and the control instruction output by the lighting control end is divided by the resistors R16 and R17. The lighting controlled end receives a high level and the lighting control module 600 controls the lighting light source 700 to emit light.
