[0002] With the rapid development of smart homes, more and more smart devices have emerged, and smart lamps are a typical example. Smart lamps are equipped with antennas inside, and external terminals (such as mobile phones, remote controls, etc.) use wireless communication methods such as Bluetooth and WIFI to communicate with the control circuit of smart lamps through antennas, thereby controlling the operation of smart lamps.

[0003] In order to put the antenna into the smart lamp, a plastic part is usually set between the lamp head and the lampshade to provide an installation position for the antenna, or the antenna is directly installed on the lamp board. However, the setting of the plastic part increases the volume of the smart lamp, affects the aesthetics, and increases the cost of the smart lamp; and the solution of setting the antenna on the lamp board has higher requirements on the internal structure of the smart lamp, which must ensure the wireless transmission performance of the antenna and avoid the shadow of the light source as much as possible. The complex structure makes the manufacturing of the smart lamp difficult and increases the cost.

[0004] Therefore, there is an urgent need for an LED lamp to solve the above problems. Summary of the invention

[0045] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] This embodiment provides an LED lamp that can communicate with an intelligent control device to achieve intelligent adjustment of color, brightness, color temperature, etc. The intelligent control device can be a mobile phone, a tablet computer, a computer, or other devices with computing power and network connection capabilities, which are not specifically limited here. In other embodiments, the LED lamp can also be controlled by setting a switch device to achieve adjustment of color, brightness, color temperature, etc.

[0047] Specifically, the LED lamp can be a bulb lamp or a downlight. Figure 1 The structure of the LED lamp is shown as a bulb lamp. Figure 7 The schematic diagram of the structure of the LED lamp is shown as a downlight. Figure 1 and Figure 7 The LED lamp comprises a lamp housing component 4, a light source component 1, a heat dissipation cover 2 and a communication component 3. The light source component 1, the heat dissipation cover 2 and the communication component 3 are all arranged in the lamp housing component 4, and the lamp housing component 4 can isolate the internal components of the LED lamp from the outside world, so as to prevent the changes of the outside air or moisture from affecting the operation of the internal components, and at the same time prevent the user from directly contacting the internal components of the LED lamp and causing accidents such as electric shock.

[0048] The light source assembly 1 includes an electrically connected power board 11 and a light emitting element 12. The power board 11 can provide electrical energy to the light emitting element 12, so that the light emitting element 12 emits light for lighting. The heat dissipation cover 2 is hollow inside and has an opening. The power board 11 is arranged in the heat dissipation cover 2, and the light emitting element 12 is connected to the peripheral side of the opening of the heat dissipation cover 2. The heat dissipation cover 2 can dissipate heat for the power board 11 and the light emitting element 12, thereby ensuring the normal use of the LED lamp.

[0049] It is understandable that a thermal conductive adhesive fixing layer is filled between the heat dissipation cover 2 and the power board 11 to ensure the stability of the positioning of the power board 11 in the heat dissipation cover 2 and the rapid conduction of the temperature of the power board 11 by the heat dissipation cover 2.

[0050] like Figure 1 As shown, the light-emitting element 12 includes a panel 121 and a plurality of LED light sources 122, and the plurality of LED light sources 122 are arranged in an array and are disposed on the side of the panel 121 away from the heat dissipation cover 2. A plurality of independent LED light sources 122 can form a single high-brightness light emitting surface, and the array arrangement can make the light and brightness emitted by the LED lamp more uniform. Exemplarily, the panel 121 is a circular plate, and the plurality of LED light sources 122 are evenly arranged in a circular array. Of course, in other embodiments, the panel 121 may also be a rectangular plate, and the plurality of LED light sources 122 may also be arranged in a rectangular or other polygonal shape, which is not limited here.

[0051] Further, continue to refer to Figure 1-Figure 3 , Figure 5 and Figure 7 The heat dissipation cover 2 has a conductive function, and a through hole 21 is provided on the side of the cover body of the heat dissipation cover 2 opposite to the power board 11. The communication component 3 is arranged in the through hole 21, and the communication component 3 includes a first connection terminal 311 and a second connection terminal 321 located between the first connection terminal 311 and the light-emitting element 12, and the first connection terminal 311 and the second connection terminal 321 are electrically connected to the power board 11 respectively. That is to say, the second connection terminal 321 is used as a radiation element, the first connection terminal 311 is used as a ground terminal, and the power board 11 is used as a feeding unit. After power is turned on, a current loop can be formed between the first connection terminal 311, the heat dissipation cover 2 and the second connection terminal 321, so that a PIFA antenna communication structure is formed between the first connection terminal 311, the second connection terminal 321 and the power board 11, thereby ensuring the communication performance of the LED lamp. In addition, the communication structure is integrated on the heat dissipation cover 2, and the antenna does not need to be placed on the lamp board, which effectively saves the structural space inside the LED lamp, and the production and assembly method is simpler, the production efficiency is higher, and the cost is relatively reduced.

[0052] It should be noted that the heat dissipation cover 2 having a conductive function is a necessary and sufficient condition for forming a PIFA antenna after the first connection terminal 311 and the second connection terminal 321 are powered on. In this embodiment, the heat dissipation cover 2 is preferably a metal heat dissipation cover, such as an aluminum heat dissipation cover. Other heat sinks made of materials that can conduct electricity and heat can be used, such as conductive ceramics, graphene or conductive polymers, which are not limited here. Therefore, lamps with a heat sink structure made of materials that can conduct electricity and heat can be included in the protection scope of this application.

[0053] Specifically, Figure 4-Figure 6 and Figure 8 As shown, the through hole 21 further includes a first connection portion 31 and a second connection portion 32. One end of the first connection portion 31 extends into the through hole 21 to form a first connection terminal 311; one end of the second connection portion 32 extends into the through hole 21 to form a second connection terminal 321. The first connection portion 31 and the second connection portion 32 are spaced apart along the circumference of the through hole 21. That is, the second connection portion 32 may be an L-shaped structure (refer to Figure 4 ), or it can be a one-line structure (refer to Figure 6 ), it is only necessary to ensure that the second connection terminal 321 is located between the first connection terminal 311 and the light emitting element 12, so that the first connection terminal 311 and the second connection terminal 321 can form the basic structure of the PIFA antenna after power is turned on.

[0054] In this embodiment, the first connection portion 31 is integrally formed with the heat dissipation cover 2, and the second connection portion 32 is integrally formed with the heat dissipation cover 2. The first connection portion 31 and the second connection portion 32 are both formed by stamping on the cover body of the heat dissipation cover 2, and the first connection portion 31 and the second connection portion 32 are integrally formed with the heat dissipation cover 2, which saves antenna materials, optimizes costs, simplifies production and assembly steps, and improves processing efficiency.

[0055] More specifically, the angle between the line connecting the first connection terminal 311 and the second connection terminal 321 and the vertical direction is less than 90°. The first connection terminal 311 and the second connection terminal 321 are both located in the arc surface formed by the through hole 21, and in the vertical direction, the second connection terminal 321 is closer to the light emitting element 12 than the first connection terminal 311.

[0056] Preferably, if Figure 4 and Figure 6 As shown, the connection line between the first connection terminal 311 and the second connection terminal 321 is parallel to the vertical direction. Such an arrangement is convenient for processing and manufacturing, and has a high aesthetic appearance.

[0057] More specifically, in this embodiment, the first connection terminal 311 is conductively connected to the ground wire of the power board 11, and the second connection terminal 321 is conductively connected to the core wire of the power board 11. In the above configuration, the power board 11 serves as a feeding network, the second connection terminal 321 serves as a radiating element, and the first connection terminal 311 serves as a ground plane, forming the basic structure of the PIFA antenna. The working principle of the PIFA antenna is to transmit electromagnetic energy to the radiating element through the feeding network, and then the radiating element radiates energy outward in the form of electromagnetic waves; the function of the ground plane is to form a reflection, reflecting the electromagnetic waves generated by the radiating element back to the radiation space, thereby forming an omnidirectional radiation pattern.

[0058] In this embodiment, by integrating the communication component 3 on the heat dissipation cover 2, the concealed design of the antenna is realized, and the internal space of the LED lamp is effectively simplified. At the same time, the antenna structure design provided in this embodiment can be adopted for other lamps containing metal heat sinks (or heat sink materials that can achieve both electrical and thermal conductivity), making the antenna solution simpler and more cost-effective.

[0059] Continue to refer to Figure 1-Figure 3 and Figure 7The lamp housing assembly 4 includes a shell 41 and a lamp holder 42. The shell 41 is open at both ends and hollow inside. The shell 41 is sleeved outside the heat dissipation cover 2. The lamp holder 42 is connected to one end opening of the shell 41 and is electrically connected to the power board 11. The light-emitting element 12 is located at the other end opening of the shell 41. The shell 41 is open at both ends and hollow inside, that is, the shell 41 includes a hollow cavity for accommodating other components of the LED lamp. The lamp holder 42 is connected to one end of the shell 41. The lamp holder 42 is the end of the LED lamp and is the connection part with the external power supply. At the same time, the power board 11 is also electrically connected to the light-emitting element 12, so the LED lamp can be connected to electricity through the lamp holder 42 to make the light-emitting element 12 emit light.

[0060] Specifically, the lamp holder 42 and the housing 41 may be connected and fixed by means of threaded connection or the like, which is not specifically limited here.

[0061] Optionally, the lamp housing assembly 4 further includes a light-transmitting cover 43, which is connected to an end of the housing 41 away from the lamp holder 42 and is disposed outside the light-emitting element 12. The light-transmitting cover 43 can converge the light generated by the light-emitting element 12 to improve the light brightness of the LED lamp. The light-transmitting cover 43 can also isolate the internal components of the LED lamp from the outside world, thereby preventing changes in the outside air or moisture from affecting the operation of the internal components, and can also prevent users from directly contacting the internal components of the LED lamp and causing accidents such as electric shock.

[0062] More specifically, the lamp housing assembly 4 further includes a metal member 44, which is disposed at one end of the lamp holder 42 away from the housing 41, and the bottom of the metal member 44 is in contact with the external power source. For example, the external power source is a mains power line, which is introduced into the lamp holder 42 through one end of the lamp holder 42 close to the metal member 44. At this time, the metal member 44 is screwed so that the metal member 44 is connected and fixed to the lamp holder 42, so that the mains power line can stably supply power to the lamp of the LED lamp.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
