[0043] The lamp holder 10 includes a threaded metal portion 11, a bottom metal contact portion 12, and a conductive connecting member 13. The threaded metal portion 11 is electrically connected to the control circuit board 40 through the conductive connecting member 13, and the bottom metal contact portion 12 is electrically connected to the control circuit board 40 through the conductive connecting member 13. The threaded metal portion 11 is used to connect an external AC zero line, and the bottom metal contact portion 12 is used to connect an external AC live line.

Correspondingly, the control circuit board 40 further includes an AC-DC conversion module 43. One end of the AC-DC conversion module 43 is electrically connected to the threaded metal portion 11 and the bottom metal contact portion 12, and the other end of the AC-DC conversion module 43 is electrically connected to the main control unit 41.

[0044] In some embodiments, referring to Figure 5 , Figure 5 is another perspective view of the LED bulb provided in an embodiment of the present application. The control circuit board 40 can be integrated on the LED lamp panel 20. The LED lamp panel 20 and the control circuit board 40 can be provided as an integrated structure, that is, the LED lamp panel 20 can include the control circuit board 40 and a plurality of light emitting unit groups 21. The LED lamp panel 20 and the control circuit board 40 can also be provided as separate integrated structures, that is, the control circuit board 40 does not belong to a part of the LED lamp panel 20, and the control circuit board 40 is electrically connected to the LED lamp panel 20. For example, the control circuit board 40 can be connected to the LED lamp panel 20 through wires or contacts.

[0045] In some embodiments, the light emitting unit 211 can include a single-color-temperature single-color light emitting unit or a multi-color light emitting unit or a multi-color-temperature light emitting unit or a combination of multi-color-temperature and multi-color light emitting unit.

[0046] It should be noted that the number of light emitting units 211 in each light emitting unit group 21 can be set according to the light emitting requirement, and the embodiments of the present application are not limited specifically.

[0047] It should be noted that the type of light emitting unit 211 in each light emitting unit group 21 can be set according to the light emitting requirement, and the embodiments of the present application are not limited specifically. For example, in some embodiments, each light emitting unit 211 in the same light emitting unit group 21 can be set as a same color temperature and same color light emitting unit, for example, each light emitting unit 211 in the same light emitting unit group 21 can be set as a red light LED chip, so that each red light LED chip in the light emitting unit group 21 can emit red light simultaneously through the corresponding driving unit 42. In some embodiments, each light emitting unit 211 in the same light emitting unit group 21 can also be set as a different color temperature and / or different color light emitting unit (for example, including more than three color LED lamp beads), for example, each light emitting unit 211 in the same light emitting unit group 21 can be set as a red LED, a green LED, a blue LED and a white LED respectively. So that the red LED, the green LED, the blue LED and the white LED in the light emitting unit group 21 can emit light simultaneously through the corresponding driving unit 42, and the light mixing effect can be achieved.

[0048] In some embodiments, the LED lamp plate 20 is a three-dimensional structure, and the three-dimensional structure of the LED lamp plate 20 can be a column, a sphere, a hemisphere, a cone and the like. Each light emitting unit 211 in the same light emitting unit group 21 can be arranged on the LED lamp plate 20 in a circumferential, horizontal or longitudinal direction. For example, the LED lamp plate 20 is a column, and the LED lamp plate 20 is arranged on the LED lamp plate 20 in a circumferential direction. Figure 6-8 , Figure 6 is an example diagram of the arrangement of each light emitting unit on the LED lamp plate provided by an embodiment of the present application, Figure 7 is an example diagram of the first grouping of the light emitting units on the LED lamp plate provided by an embodiment of the present application, Figure 8is a second grouping example diagram of the light emitting units on the LED lamp panel provided by an embodiment of the present application. The light emitting units 211 are arranged in a circle on the LED lamp panel 20, and there are four circles. Each light emitting unit 211 in a circle can form a light emitting unit group 21, that is, there are four light emitting unit groups in total, which can be numbered as a first light emitting unit group A1, a second light emitting unit group A2, a third light emitting unit group A3, and a fourth light emitting unit group A4. Each light emitting unit group 21 can realize control of different color temperatures, so as to form a multi-color concentric circle illumination effect in the illumination range, and realize more personalized light effects. If each light emitting unit 211 arranged in a circle is arranged in the order of a red LED, a green LED, a blue LED, and a white LED, each red LED in the same vertical direction can form a light emitting unit group R, each green LED in the same vertical direction can form a light emitting unit group G, each blue LED in the same vertical direction can form a light emitting unit group B, and each white LED in the same vertical direction can form a light emitting unit group W.

[0049] It should be noted that the LED lamp panel 20 is a three-dimensional structure, and the light emitting units 211 can be arranged on the LED lamp panel 20 in different arrangement manners. For example, the light emitting units 211 can be arranged on the LED lamp panel 20 in a linear arrangement, a matrix arrangement, a circular or annular arrangement, a bionic arrangement, a random arrangement, or the like. The grouping of the light emitting units 211 on the LED lamp panel 20 can be performed according to the types and arrangement manners of the light emitting units 211, and the grouping manner and the number of the light emitting unit groups 21 are not limited in the embodiments of the present application. When the light emitting unit group 21 contains only one light emitting unit 211, it is indicated that the corresponding driving unit 42 is used to drive and control the light emitting unit 211 in the light emitting unit group 21. When the light emitting unit group 21 contains a plurality of light emitting units 211, it is indicated that the corresponding driving unit 42 is used to simultaneously drive and control the plurality (all) of light emitting units 211 in the light emitting unit group 21. The light emitting unit groups 21 are connected in parallel, and the light emitting units 211 in the light emitting unit group 21 can be connected in series, in parallel, or in a mixed manner.

[0050] In some embodiments, the light emitting parameters of the light emitting units 211 can include brightness and / or color temperature. Therefore, the corresponding driving unit 42 can control the brightness and / or color temperature of each light emitting unit 211 in the corresponding light emitting unit group 21. For example, the driving unit 42 can be an independent PWM chip, which can control the brightness and / or color temperature of each light emitting unit 211 in the corresponding light emitting unit group 21 through a PWM signal.

[0051] In some embodiments, the light-transmitting lampshade 30 can be spherical, and the light-transmitting lampshade 30 can be a glass light-transmitting lampshade or a heat-conducting plastic light-transmitting lampshade. Since the light-transmitting lampshade 30 is directly fixedly connected to the lamp holder 10, and the LED lamp panel 20 and the control circuit board 40 are both arranged in the light-transmitting lampshade 30, the structure of the LED lamp bulb can be simplified, the overall size of the LED lamp bulb can be reduced, and by increasing the surface area of the light-transmitting lampshade 30, the illumination area of the LED lamp bulb can be increased, so that the illumination effect of the LED lamp bulb can be improved, and at the same time, the safety hazard caused by the exposure of metal components can also be avoided.

[0052] With reference to Figure 9-10 , Figure 9 is a first circuit connection schematic diagram of an LED lamp bulb provided in an embodiment of the present application, Figure 10 is a second circuit connection schematic diagram of an LED lamp bulb provided in an embodiment of the present application. In some embodiments, the control circuit board 40 can further be provided with a wireless transmission module 44, the wireless transmission module 44 being electrically connected to the master control unit 41, and the wireless transmission module 44 being used for communication connection with an external control device. The external control device can be a controller (which can be arranged in a control box), a smart terminal (such as a mobile phone, a tablet computer, a smart watch, a smart television, etc.), a control console (such as including control buttons and a control circuit capable of sending different PWM signals, and by operating the control buttons, corresponding PWM signals can be sent to the wireless transmission module). The wireless transmission module 44 is a module for wireless transmission by using wireless technology. The wireless transmission module 44 can include a Wi-Fi module, a Bluetooth module, a ZigBee module, etc. The master control unit 41 is electrically connected to each driving unit 42, when the light-emitting unit group 21 includes only one light-emitting unit 211, each light-emitting unit 211 can be controlled individually, and when the light-emitting unit group 21 includes multiple light-emitting units 211, the light-emitting units 211 can be controlled in groups.

[0053] In the embodiment of the present application, the external control device is in communication connection with the wireless transmission module 44, so that the external control device can generate a dimming signal and send it to the wireless transmission module 44. The wireless transmission module 44 can receive the dimming signal sent by the external control device, and transmit the dimming signal to the master control unit 41, so that the master control unit 41 can control each driving unit 42 based on the dimming signal, to control the light-emitting parameters of each light-emitting unit 211 in the corresponding light-emitting unit group 21, so that different light effect requirements in different shooting scenes can be met.

[0054] With reference to Figure 9The number of the driving units 42 is the same as the number of the light emitting unit groups 21, and each driving unit 42 is connected with one light emitting unit group 21. That is, each light emitting unit 211 in each light emitting unit group 21 is simultaneously controlled by the corresponding driving unit 42. When the light emitting unit group 21 contains only one light emitting unit 211, each light emitting unit 211 is controlled by one corresponding driving unit 42, that is, the individual control of each light emitting unit 211 can be realized. When the light emitting unit group 21 contains multiple light emitting units 211, the multiple light emitting units 211 in the light emitting unit group 21 are controlled by one corresponding driving unit 42, that is, the grouping control of each light emitting unit 211 can be realized.

[0055] With reference to Figure 10 The number of the driving units 42 is multiple, and one driving unit 42 is connected with the corresponding multiple light emitting unit groups 21. That is, the light emitting parameters of the multiple light emitting unit groups 21 are controlled by the corresponding one driving unit 42, which can reduce the cost by reducing the setting of the driving unit 42 while meeting the light efficiency requirements.

[0056] It should be noted that the main control unit 41 is mainly used for controlling the operation of each driving unit 42, such as controlling a certain driving unit 42 to work, so that the driving unit 42 sends a corresponding PWM signal to control the light emitting parameters of the light emitting unit 211 electrically connected with the driving unit 42. Or control a certain driving unit 42 not to work, so that the driving unit 42 does not send a corresponding PWM signal to control the light emitting unit 211 electrically connected with the driving unit 42 not to light up. The main control unit 41 can be a single-chip microcomputer, a microcontroller or a main control circuit.

[0057] The driving unit 42 can be a single (single-channel) PWM chip, a single PWM unit in a multi-channel output PWM chip, or a control module (time division multiplexing PWM output) composed of a single-channel PWM chip and one of the multiple switching tubes. The driving unit 42 can be a driving circuit.

[0058] In the embodiment of the application, each light emitting unit 211 on the LED lamp panel 20 can be individually controllable or controllable in groups, the light emitting units in the same group can be connected in series, parallel or mixed, and driven and controlled by the corresponding driving unit 42. The driving signal can be a PWM signal, and the light emitting brightness of the corresponding light emitting unit 211 can be adjusted by adjusting the duty cycle of the PWM signal. The light emitting units between different groups can realize mixed light effect of different colors and color temperatures through different PWM signals, and realize point control of three-dimensional multi-color light source.
