The lampshade 730 can be transparent or translucent. The bottom end of the connecting base 710 can be provided with a conductive plate connected to the AC power supply, and the conductive plate is connected to the input end of the power modulation module 100.

[0039] In some embodiments of the present invention, Figure 1As shown, the connection base 710 can be plugged into the electrical socket of the AC power supply, and the plug-in charging port 200 is set on the connection base 710. The plug-in direction of the connection base 710 is the same as the plug-in direction of the plug-in charging port 200.

[0040] The outer wall of the connecting socket 710 is provided with an external thread structure, and the inner wall of the electrical connection socket of the AC power supply can be provided with an internal thread structure. The external thread structure and the internal thread structure cooperate to enable the connecting socket 710 to be installed on the electrical connection socket, and the AC power supply thereby inputs electrical energy to the power modulation module 100.

In addition, it can save space and is easy to use.

[0041] In some embodiments of the present invention, Figure 5 As shown, a first circuit board 840 and a second circuit board 850 are arranged in the upper and lower spaces in the connecting seat 710, wherein the first circuit board 840 is arranged away from the lighting lamp group 720, and the second circuit board 850 is arranged close to the lighting lamp group 720, the power modulation module 100 is arranged on the first circuit board 840, and the lighting control module 600 is arranged on the second circuit board 850.

[0042] The electronic components placed on the first circuit board 840 are used to access an AC power supply, which is relatively high voltage, while the electronic components placed on the second circuit board 850 are used to access a DC power supply or to drive the lighting group 720, which is relatively low voltage. The first circuit board 840 and the second circuit board 850 are separated by high and low voltage to reduce the impact of mutual interference.

[0043] In some embodiments of the present invention, a mounting post 740 is provided in the cavity, and the mounting post 740 is vertically penetrated on the second circuit board 850. The mounting post 740 can also continue to penetrate on the first circuit board 840. The lighting lamp group 720 includes a first LED lamp group 721 and a second LED lamp group 722. The first LED lamp group 721 is surrounded by the peripheral wall of the mounting post 740, and the second LED lamp group 722 is arranged on the surface of the second circuit board 850.

The lampshade 730 can be in the shape of a long strip, and the mounting post 740 extends along the shape of the lampshade 730. The multiple LED lamp beads in the first LED lamp group 721 are arranged around the peripheral wall of the mounting post 740 to form at least one circle of LED lamp ring. The LED lamp ring can have multiple circles, and the multiple circles of LED lamp rings are distributed along the length direction of the mounting post 740. The circumferentially distributed first LED lamp group 721 allows the bulb body to emit light evenly in the circumferential direction, and the second LED lamp group 722 is arranged on the surface of the second circuit board 850 facing the lampshade 730. The second LED lamp group 722 emits light upward around the mounting post 740, so that light can be evenly emitted from all directions of the lampshade 730.

[0045] The mounting column 740 can be made of aluminum alloy or steel. The mounting column 740 is hollow, and 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 can 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 can include LED lamp beads of multiple colors. The LED lamp beads of different colors in the second LED light group 722 can be selectively lit to present multiple colors. For example, the LED lamp beads of the second LED light group 722 include RGB multi-colors, which can be used as atmosphere lights to change the color of the environment. Among them, the combination of white light and RGB multi-colors can be used to present luminous effects such as flames, colorful gradients, and jumping breathing.

[0047] The bulb body can also be provided with components such as a timing switch, a charging indicator, and a power indicator. For example, the timing switch can set a timing signal to control the timing of the lighting source 700 to turn on and off. The power indicator can indicate the power level through indicator lights of multiple colors. A low power level is red, a medium power level is flashing yellow, and a full power level is flashing green.

[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 seat 710 . The control button 820 may be connected to the lighting control module 600 . The user may press the control button 820 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 judges the light intensity feedback signal output by the control instruction output by the charging management module 300 and controls the control instructions input by components such as the timing switch, wireless receiving element 830 and 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] Diode D6 isolates the output end of the plug-in charging port 200 and the power modulation module 100 from the charging control end and the energy storage module 500. The voltage output by the energy storage module 500 does not affect the output end of the plug-in charging port 200 and the power modulation module 100, and thus does not affect the power sampling end's judgment of whether there is AC power input. Resistor R13 limits the charging voltage current, 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. 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. Resistors R14 and R15 divide the input voltage of the power supply and determine whether there is an AC power input based on 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 turned off, and the control instruction output by the lighting control end is divided by 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.

[0058] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0059] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that the present invention can be further modified without departing from the principles and purposes of the present invention.

[0060] Various changes, modifications, substitutions and variations can be made to these embodiments.
