[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0051] In an exemplary embodiment, a portable AC energy storage bulb fan lamp is provided, comprising: an LED light source assembly, a fan assembly, a battery module, a control circuit board and a cylindrical shell; the LED light source assembly is connected to one side of a fixed portion of the fan assembly, and the other side of the fixed portion of the fan assembly is connected to the cylindrical shell, and the battery module and the control circuit board are both arranged in the cylindrical shell; the control circuit board is respectively connected to the LED light source assembly, the fan assembly and the battery module, and the control circuit board is used to control the external AC power supply to supply power to the LED light source assembly and the fan assembly and charge the battery module when the LED light source assembly and the fan assembly are in working state and there is an external AC power supply; when the LED light source assembly and the fan assembly are in working state and there is no external AC power supply, and the battery pack in the battery module is sufficiently charged, the battery module is controlled to supply power to the LED light source assembly and the fan assembly.

[0052] In an exemplary embodiment, Figure 1 As shown, Figure 1 (a) is the main view. Figure 1(b) is a three-dimensional diagram, the above-mentioned LED light source assembly includes: a light source installation compartment T03, a light source aluminum substrate T02, a main light source ( Figure 1 Not shown), auxiliary light source ( Figure 1 The light source aluminum substrate T02 is arranged in the light source mounting compartment T03, and the light shield T01 is snapped on the light source mounting compartment T03. The main light source and the auxiliary light source both include a plurality of LED lamp beads, and the plurality of LED lamp beads are distributed on a side surface of the light source aluminum substrate T02 facing the light shield T01; one end of the light source mounting compartment T03 away from the light shield T01 is connected to one side of the fixing part of the fan assembly.

[0053] In an exemplary embodiment, Figure 1 As shown, the above-mentioned fan assembly includes: a driving motor T05, a fixing part ( Figure 1 Not shown), the rotating part ( Figure 1 The fixed part is connected to the rotating part through a bearing; the output shaft of the driving motor T05 is connected to the shaft of the rotating part, and the plurality of blades T04 are detachably mounted on the outer circumferential side of the rotating part.

[0054] In an exemplary embodiment, Figure 1 As shown, the battery module includes: a battery pack (including a battery T08 and a battery T07) and a lithium battery installation compartment T06; the battery pack is arranged in the lithium battery installation compartment T06; a plurality of first studs T13 and a plurality of second studs T14 are arranged on the outer shell of the lithium battery installation compartment T06; the length of the second studs T14 is greater than the first studs T13; a plurality of first threaded holes and a plurality of through holes are opened on the control circuit board, and a plurality of second threaded holes are opened on the cylindrical outer shell T10; the plurality of first studs and the plurality of first threaded holes are arranged one by one, and the first studs and the first threaded holes are connected by screws, such as Figure 2 As shown, a plurality of second studs are arranged in one-to-one correspondence with a plurality of through holes, and a plurality of through holes are arranged in one-to-one correspondence with a plurality of second threaded holes. The second studs pass through the through holes and are connected to the second threaded holes by screws T11.

[0055] To continue providing lighting and fan needs after a power outage, a battery pack is necessary.

[0056] The driving motor commonly used in the fan assembly is a three-phase motor, which is closed-loop controlled and basically has constant power output. The operating voltage range of the three-phase motor is 12V to 24V, and the maximum speed output power is about 10W. In addition, the auxiliary light source provided in this application is also around 10W, that is, the maximum discharge power after a power outage is around 20W. As an energy storage product, the battery life is generally required to be at least 2 hours, which requires that the energy capacity of the battery pack must be large enough. Considering that the bulb fan lamp of this application has a small space and contains a three-phase motor and other structures, this puts relatively high requirements on the energy capacity of the battery pack, and a lithium battery with high energy density must be used, such as an 186503.7V ternary lithium battery.

[0057] Based on the above considerations, the battery pack can consider the use of four 186503.7V lithium batteries in series, with each lithium battery having a capacity of about 2800mAH. This configuration can achieve an energy storage discharge power of 20W and a duration of about 2 hours, meeting the design requirements.

[0058] The bulb fan lamp of the present application has a small space. Considering that the weight of four lithium batteries accounts for nearly half of the weight of the entire lamp, the lithium batteries need to be arranged in the middle of the bulb fan lamp to avoid being arranged too high or too low. Figure 3 This is the overall structure diagram of the bulb fan lamp of this application. Figure 4 The embodiment of the present application arranges the lithium battery installation chamber T06 just above the drive motor T05, in groups of two, for a total of two groups, distributed on both sides of the lithium battery installation chamber T06; the control circuit board is above the lithium battery installation chamber T06, and is fixed to the two first studs T13 on the periphery of the lithium battery installation chamber T06 by two screws; the outer cylindrical shell T11 is fixed to the four second studs T14 on the periphery of the lithium battery installation chamber T06 by four screws.

[0059] The structural layout of the present application is reasonable, the space is fully utilized, and the height of the lamp is only about 18 mm greater than that of the existing lamp.

[0060] In order to reduce the height of the lamp as much as possible, the two sets of lithium batteries are not stacked upright, but tilted toward the middle of the battery compartment with an angle of about 30 degrees, which can reduce the height by about 5mm.

[0061] In addition, due to the small space of the bulb fan lamp of the present application, the space above the control circuit board is high in the middle and low at the edges, requiring relatively tall electronic components (such as EE inductor transformers, high-voltage electrolytic capacitors, etc.) to be arranged in the middle position as much as possible.

[0062] In an exemplary embodiment, Figure 1 As shown, a lamp holder T12 is arranged outside the cylindrical shell, and the lamp holder T12 is used to connect to the external AC power supply.

[0063] In another exemplary embodiment, Figure 5 As shown, the above-mentioned control circuit board includes: a rectifier circuit 101, a DC / DC constant voltage circuit 110, a main light source branch, an auxiliary light source branch, a battery charging and discharging branch, a main control circuit 140, an auxiliary control circuit 210 and a motor driving circuit 130; the main light source 105 in the LED light source assembly is arranged in the main light source branch, and the auxiliary light source 201 in the LED light source assembly is arranged in the auxiliary light source branch; the battery pack in the battery module is arranged in the battery charging and discharging branch; the input end of the rectifier circuit 102 is connected to the external AC power supply (AC1 / AC2) through the switch 101, and the output end of the rectifier circuit 102 is connected to the main light source branch; the output end of the rectifier circuit 102 is also connected to the input end of the DC / DC constant voltage circuit 110; the output end of the DC / DC constant voltage circuit 110 is connected to the input end of the motor driving circuit 130, and the motor driving circuit 13 The output end of the DC / DC constant voltage circuit 110 is connected to the power input interface of the driving motor in the fan assembly; the output end of the DC / DC constant voltage circuit 110 is also connected to the auxiliary light source branch and the battery charge and discharge branch respectively; the auxiliary control circuit 210 is respectively connected to the on-off control end of the auxiliary light source branch and the on-off control end of the battery charge and discharge branch, and the auxiliary control circuit 210 is used to control the battery charge and discharge branch to be turned on and the auxiliary light source branch to be turned on when the LED light source assembly and the fan assembly are in working state, there is no external AC power supply, and the battery pack is fully charged; when the LED light source assembly and the fan assembly are in working state, there is an external AC power supply, and the battery pack is insufficiently charged, the battery charge and discharge branch is controlled to be turned on; the main control circuit is respectively connected to the adjustment control end of the main light source branch and the adjustment control end of the auxiliary light source branch, and the main control circuit is used to adjust the brightness of the main light source and the auxiliary light source.

[0064] Among them, the auxiliary light source branch includes: a first resistor 201, a first NMOS tube 203 and a second NMOS tube 204; the anode of the auxiliary light source 201 is connected to the positive electrode of the output end of the DC / DC constant voltage circuit 110, the cathode of the auxiliary light source 201 is connected to one end of the first resistor 202, the other end of the first resistor 202 is connected to the drain of the first NMOS tube 203, the source of the first NMOS tube 203 is connected to the drain of the second NMOS tube 204, and the source of the second NMOS tube 204 is connected to the negative electrode of the output end of the DC / DC constant voltage circuit 110; the gate of the first NMOS tube 203 is connected to the auxiliary control circuit 210, and the gate of the second NMOS tube 204 is connected to the main control circuit 140.

[0065] like Figure 6 As shown, the battery charge and discharge branch includes: a first PMOS transistor 226 , a second PMOS transistor 225 , a third NMOS transistor 228 and a second resistor 227 .

[0066] The drain of the first PMOS tube 226 is connected to the positive electrode of the output end of the DC / DC constant voltage circuit 110, the source of the first PMOS tube 226 is connected to the source of the second PMOS tube 225, the drain of the second PMOS tube 225 is connected to the positive electrode of the battery pack, and the negative electrode of the battery pack is connected to the negative electrode of the output end of the DC / DC constant voltage circuit 110; the drain of the third NMOS tube 228 is respectively connected to the gate of the first PMOS tube 226, the gate of the second PMOS tube 226 and one end of the second resistor 227, the other end of the second resistor 227 is respectively connected to the source of the first PMOS tube 226 and the source of the second PMOS tube 225, the source of the third NMOS tube 228 is connected to the negative electrode of the output end of the DC / DC constant voltage circuit 110; the gate of the third NMOS tube 228 is connected to the auxiliary control circuit 210.

[0067] The main light source branch includes a constant current regulation circuit 150; the anode of the main light source 106 is connected to the positive pole of the output end of the rectifier circuit 102, the cathode of the main light source 106 is connected to the input end of the constant current regulation circuit 150, and the output end of the constant current regulation circuit T106 is connected to the negative pole of the output end of the rectifier circuit 102; the control end of the constant current regulation circuit 150 is connected to the main control circuit 140.

[0068] The auxiliary light source 201 of the present application is composed of a plurality of 3V lamp beads connected in series and in parallel, and the first resistor 202 is used as a current limiting resistor to adjust the working current of the auxiliary light source 201 .

[0069] Figure 6 It is a battery charging and discharging branch, which contains a battery pack and a corresponding control circuit. The battery pack includes four lithium batteries 221, 222, 223, and 224 connected in series. The DC / DC constant voltage circuit 110 provides charging current for the lithium battery. The auxiliary control circuit 210 sends the output signal EMON to the main control circuit 140. If the output signal EMON is high, it indicates that the system is in energy storage and discharge mode.

[0070] The auxiliary control circuit 210 determines the status of the AC power grid and the switch 101. By determining the status of the switch 101, it determines whether the LED light source assembly and the fan assembly are in working condition. By determining the AC power grid, it determines whether there is an external AC power supply. The specific process is as follows.

[0071] First, if the switch 101 is in the off state, the output signal EMON is at a low level, and the system is in the light-off state.

[0072] Second, if the switch 101 is in a closed state and the AC power grid is supplying power normally, the output signal EMON is at a low level. At this time, the system is in AC power mode, and the CV node provides charging current for the internal battery pack. The CV node voltage (that is, the output voltage of the AC / DC constant voltage circuit 110) is slightly higher than 16.8V (the total voltage of the four 3.7V lithium batteries after being fully charged is 16.8V). It cannot be too high (low efficiency) or too low (may not be fully charged).

[0073] Third, if the switch 101 is in a closed state and the AC power grid is in a power outage state, the output signal EMON is at a high level, and the system is in an energy storage and discharge mode.

[0074] When EMON is at a low level, the second NMOS tube 204 is in a disconnected state. No matter what the state of the dimming signal DIM of the main control circuit 140 is, the auxiliary light source 201 will not be turned on.

[0075] Figure 6 In the figure, the first PMOS tube 225 and the second PMOS tube 226 constitute a direct-release switch in the discharge state. In the discharge state, the EMON signal is high, and the third NMOS tube 228 will turn on and pull down the gates of the first PMOS tube 226 and the second PMOS tube 225, that is, turn on the discharge direct-release switch, and directly output the sum of the voltages of the four lithium batteries to the CV circuit node with low impedance. EMON is an important control signal: when the following three conditions are met at the same time, power outage state + switch 101 is closed + the four lithium batteries 221, 222, 223, and 224 are fully charged, EMON will be high, and other conditions are low. When EMON is high, it means that the system is in energy storage discharge mode, and this high-level signal is sent to Figure 5 An IO pin of the main control circuit 140 in the energy storage and discharge mode. In the energy storage and discharge mode, the infrared receiving head of the main control circuit 140 receives the control of the remote control and the switch 101, and executes the control of the auxiliary light source 201 and the three-phase motor 105 (direct control is performed by the motor drive circuit 130). The software control method is the same as in the AC mode. The control signal of the light source (the light source in the AC mode is the main light source 106, and in the energy storage and discharge mode, the light source is the auxiliary light source 201) is DIM, and the control signal of the fan motor is also FAN. DIM and FAN are used to adjust the brightness of the light source and the speed of the fan, respectively.

[0076] The sources of the first PMOS tube 226 and the second PMOS tube 225 are connected together, the drain of the second PMOS tube 225 is connected to the positive electrode of the lithium battery 224, the drain of the first PMOS tube 226 is connected to the CV node, one end of the second resistor 227 is connected to the common source of the first PMOS tube 226 and the second PMOS tube 225, and the other end is connected to the drain of the third NMOS tube 228 together with the gates of the first PMOS tube 226 and the second PMOS tube 225, the main purpose of which is to well disconnect the positive electrode of the lithium battery 224 from the CV node. When EMON=0, the third NMOS tube 228 is disconnected, and the second resistor 227 will pull up the gate voltage of the first PMOS tube 226 and the second PMOS tube 225, so that the direct-release switch formed by the first PMOS tube 226 and the second PMOS tube 225 is in the disconnected state, no matter how many volts the CV node level is, it is ensured that no leakage current leaks from the four lithium batteries to the CV node.

[0077] The main control circuit 140 and the auxiliary control circuit 210 can be implemented using a single chip microcomputer.

[0078] In the embodiment of the present application, the driving motor power is only 10W, and the light source (main light source or auxiliary light source) power is also 10W. The present application can also be expanded to a higher-power AC energy storage fan lamp, for example, the motor power can reach 15W, the light source power can also reach 15W, and the motor diameter is larger.

[0079] In the embodiment of the present application, four 18650 3.7V lithium batteries are used in series. In fact, similar functions can be achieved by using three or five (or even more) lithium batteries in series, which is also within the scope of the patent rights claimed by the present invention.
