[0025] Specifically, in the embodiment of the present application, the light-emitting unit 20 and the control chip 30 are arranged in the package shell 10, and the control chip 30 is electrically connected to the light-emitting unit 20 to control the operation of the light-emitting unit 20. The package shell 10 is provided with a first positive pin 11, a second positive pin 12 and a control signal pin 13 arranged at intervals from each other. The first positive pin 11 is connected to the light-emitting unit 20 and is used to connect the positive electrode of the power module 50 to supply power to the light-emitting unit 20. The second positive pin 12 is connected to the control chip 30 and is used to connect the positive electrode of the power module 50 to supply power to the control chip 30, and the control signal pin 13 is connected to the control chip 30. By arranging the first positive pin 11, the second positive pin 12 and the control signal pin 13 spaced from each other on the package shell 10 of the light-emitting module 100, the first positive pin 11 is connected to the light-emitting unit 20, and the second positive pin 12 is connected to the control chip 30, so that the power supply of the light-emitting unit 20 and the power supply of the control chip 30 are independently separated. By setting the independent first positive pin 11 and the second positive pin 12, on the one hand, it is possible to avoid electromagnetic interference or fault isolation between the control chip 30 and the light-emitting unit 20, maintain the normal power supply of the light-emitting module 100 and the normal light display, and improve the stability and reliability of the lamp 200 during operation; on the other hand, it is also possible to achieve single-point control, that is, the output values of the current and voltage of the light-emitting unit 20 and the control chip 30 can be independently controlled, thereby forming different lighting effects and improving the working efficiency of the lamp 200. In addition, the independent first positive pin 11 and the second positive pin 12 can also prevent heat transfer, avoid the heat of the light-emitting unit 20 from being directly transferred to the control chip 30, thereby improving the safety and service life of the lamp 200. At the same time, the setting is also convenient for maintenance and management, reduces the complexity and difficulty of maintenance, and thus improves the user experience.
[0026] Next, each component of the light-emitting module 100 and the specific structure of each component will be introduced one by one.
[0027] See also Figure 1 and Figure 2 In this embodiment, the packaging shell 10 is used to form a physical barrier and encapsulate the installation components to prevent external factors such as impact, humidity, dust, etc. from damaging the installation components, thereby improving the reliability and durability of the light-emitting module 100. The packaging shell 10 includes a bottom plate 15 and a light-transmitting cover 16. The light-transmitting cover 16 covers the bottom plate 15 and together defines a receiving space 161. The installation components are arranged in the receiving space 161. The installation components can be components such as the light-emitting unit 20, the control chip 30, and the heat sink, which are not limited in this embodiment.
[0028] In this embodiment, the bottom plate 15 is generally in the shape of a flat plate, which is used to provide physical support for the mounting components and play a role in heat conduction and electrical connection. The bottom plate 15 can be an insulating substrate, which has the functions of insulation and heat conduction. As an example, the bottom plate 15 can include an aluminum nitride ceramic substrate, or other insulating materials such as a plastic board and a glass fiber board. It should be noted that the bottom plate 15 can also be a high thermal conductivity substrate such as a metal substrate, a silicon material substrate, etc., and this embodiment does not limit this.
[0029] In this embodiment, the light-transmitting cover 16 is used to improve the uniformity of the emitted light. The light-transmitting cover 16 includes a cover body 162. One end of the cover body 162 is provided with an opening (not shown in the figure). The opening is connected to the accommodating space 161. The light-transmitting cover 16 is detachably connected to the bottom plate 15, which is not convenient for maintenance and management. The material of the light-transmitting cover 1610 may include ABS plastic, PC plastic or other hard plastics, which can not only reduce the weight of the light-transmitting cover 16 to achieve lightweight, but also enable the light-transmitting cover 16 to have a certain stability, thereby effectively protecting the installation components. On the other hand, the plastic material has the characteristics of low cost, good plasticity, easy processing, and not easy to break, which can reduce the production cost of the light-transmitting cover 16 and thus reduce the production cost of the lamp 200. It should be noted that the material of the light-transmitting cover 16 can also be a light-transmitting material such as light-transmitting glass and silica gel. The outer contour of the light-transmitting cover 16 can be cylindrical, cubic, spherical, etc., which is not limited in this embodiment.
[0030] In this embodiment, the light-emitting unit 20 is disposed in the accommodating space 161, and the light-emitting unit 20 is used to form lighting light or decorative light. The light-emitting unit 20 may include one or more light-emitting elements, such as the LED lamp beads, light bulbs, fluorescent tubes, optical fibers, etc. mentioned above, which are not limited in this embodiment. As an example, the light-emitting unit 20 includes at least one LED lamp bead, and the color and output power of each LED lamp bead may be different, and different colors of emitted light can be formed, thereby forming a variety of light effect lighting and improving the user's visual experience. Among them, each lamp bead can be independent of each other or connected in series step by step through a wire, which is not limited in this embodiment.
[0031] In this embodiment, the control chip 30 is arranged on the bottom plate 15 and is spaced apart from the light-emitting unit 20. On the one hand, it is convenient for the conductive wiring and the installation and maintenance of the control chip 30 and the light-emitting unit 20; on the other hand, it can reduce the concentration of heat, help the heat dissipation of the control chip 30 and the light-emitting unit 20, and extend the service life of the control chip 30 and the light-emitting unit 20. At the same time, it can also reduce the electromagnetic interference between the control chip 30 and the light-emitting unit 20, and improve the stability and reliability of the circuit. The control chip 30 is electrically connected to the light-emitting unit 20 and is used to control the brightness, color, flicker and other working characteristics of the light-emitting unit 20. Specifically, the control chip 30 is an LED chip integrated circuit, and the program with the address code is pre-written into the control chip 30, so that when the light-emitting unit 20 receives the corresponding control signal, it emits light.
[0032] In the present embodiment, the encapsulation shell 10 is provided with a first positive electrode pin 11, a second positive electrode pin 12 and a control signal pin 13 which are spaced apart from each other, and the first positive electrode pin 11, the second positive electrode pin 12 and the control signal pin 13 can be arranged on the bottom plate 15. The first positive electrode pin 11 is used to connect the positive electrode of the light-emitting unit 20 and the power module 50, and to supply power to the light-emitting unit 20. In the present embodiment, the first positive electrode pin 11 is arranged on the side wall of the bottom plate 15 and protrudes in a direction away from the accommodating space 161. In other embodiments, the first positive electrode pin 11 can also be arranged inside the accommodating space 161. The second positive electrode pin 12 and the first positive electrode pin 11 are arranged at intervals, and are used to connect the positive electrode of the control chip 30 and the power module 50, so as to supply power to the control chip 30. By setting the first positive pin 11 and the second positive pin 12 at intervals, the power supply of the light-emitting unit 20 and the power supply of the control chip 30 can be separated independently. On the one hand, it can avoid electromagnetic interference or fault isolation between the control chip 30 and the light-emitting unit 20, maintain the normal power supply of the light-emitting module 100 and the normal light display, and improve the stability and reliability of the lamp 200 during operation; on the other hand, it can also achieve single-point control, that is, the output values of the current and voltage of the light-emitting unit 20 and the control chip 30 can be independently controlled, so as to form different lighting effects and improve the working efficiency of the lamp 200. In addition, the independent first positive pin 11 and the second positive pin 12 can also prevent heat transfer, avoid the heat of the light-emitting unit 20 from being directly transferred to the control chip 30, thereby improving the safety and service life of the lamp 200. At the same time, the setting is also convenient for maintenance and management, reduces the complexity and difficulty of maintenance, and thus improves the user experience.
[0033] In this embodiment, the control signal pin 13 and the first positive pin 11 and the second positive pin 12 are arranged at intervals, and the control signal pin 13 is used to connect to the control chip 30 so that the control chip 30 can receive control instructions. It can be understood that the second positive pin 12 and the control signal pin 13 can be arranged on the side wall of the bottom plate 15 and protrude in the direction away from the accommodating space 161, or can be arranged inside the accommodating space 161.
[0034] In some embodiments, the package shell 10 is further provided with a negative electrode pin 14, which can be connected to the light-emitting unit 20 and the control chip 30 through a metal wire, and connected to the negative electrode of the power module 50, so that the light-emitting module 100 and the power module 50 form a closed loop. Similarly, the negative electrode pin 14 can be set on the side wall of the bottom plate 15 and protrude in the direction away from the accommodating space 161, or it can be set inside the accommodating space 161.
[0035] See also Figures 3 to 5 In this embodiment, a lamp 200 having a light-emitting module 100 is also provided. The lamp 200 can be a light strip or a light string, and is used to emit light of corresponding colors according to a control signal to provide lighting, indication and reminder effects. For example, white light, red light, blue light, green light or other mixed color lights are emitted. The lamp 200 includes the light-emitting module 100 mentioned above, a controller 40 and a power module 50. Specifically, the controller 40 is electrically connected to the control signal pin 13, which is responsible for receiving user instructions and adjusting the working state of the lamp 200. The controller 40 can be an integrated microcontroller 40 or a dedicated integrated circuit to realize functions such as brightness adjustment, color change, scene mode setting, timer switch and communication with a smart home system. The controller 40 also has fault detection and protection functions, such as overheat protection and short circuit protection, to ensure the safe and reliable operation of the lamp 200. The power module 50 is used to convert an external power source (such as AC or battery) into the voltage and current required by the lamp 200 to ensure the safe, stable and efficient operation of the lamp 200. The positive electrode of the power module 50 is connected to the first positive electrode pin 11 and the second positive electrode pin 12 , and the negative electrode of the power source can be connected to the negative electrode pin 14 , so that the light-emitting module 100 and the power module 50 form a closed loop.
[0036] Specifically, the power module 50 includes a current converter 51, which is used to convert alternating current into direct current required for the light-emitting module 100 to work. The current converter 51 has an input terminal 511 and an output terminal 512. The input terminal 511 receives alternating current, and the current converter 51 rectifies according to the current and voltage required for the light-emitting module 100 to work. The current converter 51 transmits the rectified voltage and current to the light-emitting module 100 through the output terminal 512, and the output terminal 512 forms the positive electrode of the power module 100. As an example, the number of the current converter 51 is one, and the output terminal of the current converter 51 is respectively connected to the first positive electrode pin 11 and the second positive electrode pin 12 of the light-emitting module 100 through two connecting wires 60 to power the light-emitting unit 20 and the control chip 30. As another example, the number of current converters 51 is two, wherein the output end 512 of one current converter 51 is connected to the first positive pin 11 through the connecting wire 60 to power the light emitting unit 20, and the output end 512 of the other current converter 51 is connected to the second positive pin 21 through the connecting wire 60 to power the control chip 30. It can be understood that the rectification process can be to increase or decrease the current output by the battery 51 to ensure its safe operation.
[0037] In this embodiment, the lamp 200 further includes a plurality of connecting wires 60, which are used to transmit electrical energy and electrical signals and to connect various components in the circuit. The connecting wires 60 can be arranged between the light-emitting module 100 and the power module 50, or between adjacent light-emitting units 20. Specifically, the surface of the connecting wire 60 is covered with an insulating layer (not shown in the figure) to prevent electrical short circuits and electric shock accidents. The connecting wire 60 can include a first positive power line 61, a second positive power line 62, and a control signal line 63, wherein the first positive power line 61 is connected between the positive electrode of the power module 50 and the first positive electrode pin 11, the second positive power line is connected between the positive electrode of the power module 50 and the second positive electrode pin 12, and the control signal line 63 is connected between the controller 40 and the control signal pin 13. The connecting wire 60 can also include a negative power line 64, which can be connected between the negative electrode of the power module 50 and the negative electrode pin 14, thereby forming a four-wire lamp 200.
[0038] In some embodiments, the number of light-emitting modules 100 may be multiple, and the multiple light-emitting modules 100 are arranged on the connecting wire 60 at intervals from each other. As an example, the multiple light-emitting modules 100 are arranged in an array and are connected in series on the connecting wire in sequence. Specifically, the multiple light-emitting modules 100 are sequentially arranged in a linear array, which may be a single row of long strips or multiple rows of long strips, and this embodiment does not limit this. As another example, the multiple light-emitting modules 100 are sequentially arranged in an annular array, which may be a circular array, a radial array or a rectangular array, and this embodiment does not limit this. It should be noted that the arrangement of the multiple light-emitting modules 100 is not limited to the linear array and the annular array mentioned above, but can also be arranged in the form of a curve array, a matrix array, etc. By setting different array arrangements and the number of arrays, a specific lighting effect or decorative effect can be formed, and the brightness and uniformity of the light distribution in the lighting area or the decorative area can be improved, thereby improving the user's visual experience.
[0039] In this embodiment, the number and color of the light-emitting units 20 of each light-emitting module 100 may be different, thereby forming a variety of lighting effects or decorative light effects. The lamp 200 may also include a lamp board 201, which may be a circuit board or a dielectric substrate, and the connecting wire 60 may be an independent metal wire or a conductive trace integrated on the lamp board 201, which is not limited in this embodiment. The lamp board 201 is also provided with a plurality of connecting pads 2011, and the connecting pads 2011 are used to install the light-emitting module 100. Specifically, the connecting pads 2011 may be connected and fixed to the first positive pin 11, the second positive pin 12, the control signal pin 13, and the negative pin 14.
[0040] In other embodiments, the metal pad can also be connected to the light-emitting module 100 through a metal wire. Multiple connection pads 2011 are connected to multiple light-emitting modules 100 in a one-to-one correspondence. At the same time, the controller 40 can output multiple control signals. Multiple control signals and multiple light-emitting modules 100 are set in a one-to-one correspondence, which can achieve single-point control and improve the working stability and reliability of the lamp 200. As an example, the control signal can include a color display signal. The control chip 30 in the light-emitting module 100 can receive the color display signal from the controller 40. When the color display signal is red, the control chip 30 controls the light-emitting unit 20 to display red; when the color display signal is blue, the control chip 30 controls the light-emitting unit 20 to display blue. It should be noted that the color signal indication color in the control signal received by the control chip 30 of the multiple light-emitting modules 100 can be the same or different, so as to form a variety of lighting effects or decorative effects.
[0041] Specifically, each light-emitting module 100 is arranged on the connection pad 2011 in a preset order, and each light-emitting module 100 has a specific address code, and each address code is different. The address code is a unique identifier for identifying and distinguishing each light-emitting module 100. The controller 40 sends an operation instruction containing address code information to the control chip 30 in each light-emitting module 100 through the control signal line 63, and the control chip 30 obtains the instruction information matching the address code, thereby realizing single-point control of the lamp 200. On the one hand, it can avoid the situation where the light-emitting modules 100 are damaged at the same time, ensuring the light-emitting reliability and stability of the lamp 200; on the other hand, it can achieve a variety of lighting or decorative effects, and improve the user experience.
[0042] As an example, the input method of the specific address code can be to write the address code to the light-emitting unit 20 in the light-emitting module 100 in advance through a burner, and then solder the light-emitting module 100 with the address code written therein to the corresponding connection pad 2011 in the address sequence. As another example, the light-emitting module 100 can be soldered to the connection pad 2011 in sequence, and then the specific address code can be written after scanning each light-emitting unit 20 through a burner.
[0043] It should be noted that when each light-emitting module 100 includes multiple light-emitting units 20, the address codes of each light-emitting unit 20 may be the same or different, and this embodiment does not limit this. It is understandable that the more address codes corresponding to the light-emitting units 20 in each light-emitting module 100, the richer the lighting effect or decorative light effect formed.
[0044] In summary, the embodiment of the present application provides a light-emitting module 100, by providing a first positive electrode pin 11, a second positive electrode pin 12 and a control signal pin 13 spaced apart from each other on the packaging shell 10 of the light-emitting module 100, the first positive electrode pin 11 is connected to the light-emitting unit 20, and the second positive electrode pin 12 is connected to the control chip 30, so that the power supply of the light-emitting unit 20 and the power supply of the control chip 30 are independently separated. By providing independent first positive electrode pins 11 and second positive electrode pins 12, on the one hand, electromagnetic interference or fault isolation between the control chip 30 and the light-emitting unit 20 can be avoided, the power supply of the light-emitting module 100 and the light display are maintained normally, and the stability and reliability of the lamp 200 during operation are improved; on the other hand, single-point control can be realized, that is, the output values of the current and voltage of the light-emitting unit 20 and the control chip 30 can be independently controlled, so as to form different lighting effects and improve the working efficiency of the lamp 200. In addition, the independent first positive pin 11 and the second positive pin 12 can also prevent heat transfer, and avoid the heat of the light-emitting unit 20 from being directly transferred to the control chip 30, thereby improving the safety and service life of the lamp 200. At the same time, the setting is also convenient for maintenance and management, reducing the complexity and difficulty of maintenance, thereby improving the user experience.
