Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and particularly to an LED lamp. Background Art

[0002] With the rapid development of smart home, more and more smart devices have emerged, and smart lamps are a typical representative among them. An antenna is arranged inside the smart lamp, and an external terminal (such as a mobile phone, a remote control, etc.) communicates with the control circuit of the smart lamp through the antenna by using wireless communication methods such as Bluetooth and WIFI, so as to control the operation of the smart lamp.

[0003] In order to place the antenna inside the smart lamp, usually a plastic part is arranged 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 arrangement of the plastic part increases the volume of the smart lamp, affects the aesthetics, and causes an increase in the cost of the smart lamp; while the scheme of arranging the antenna on the lamp board has higher requirements for the internal structure of the smart lamp. It is necessary to ensure the wireless transmission performance of the antenna and also avoid the light source shadow as much as possible. The complex structure causes difficulties in manufacturing the smart lamp and an increase in cost.

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

[0005] The purpose of the present invention is to provide an LED lamp, which integrates the communication structure on the heat dissipation cover, not only ensures the communication performance, but also effectively saves the structural space of the lamp, simplifies the assembly method, improves the production efficiency, and helps to reduce the production cost.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0020] Advantages of the present invention:

[0021] In the LED lamp provided by the present invention, the power supply board can supply electrical energy to the light-emitting component to make the light-emitting component emit light for illumination. The power supply board is arranged in the heat dissipation cover, and the light-emitting component is connected to the periphery of the opening of the heat dissipation cover, so as to dissipate heat from the power supply board and the light-emitting component through the heat dissipation cover to ensure the normal use of the lamp. The heat dissipation cover has a conductive function. A through hole is opened on the side of the cover body of the heat dissipation cover opposite to the power supply board. The first connection terminal and the second connection terminal are both located in the through hole. The second connection terminal is located between the first connection terminal and the light-emitting component.

[0045] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation on the present invention.

[0046] This embodiment provides an LED lamp, which can be communicatively connected to 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 herein. 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 Fig. shows the exploded view of the structure when the LED lamp is a bulb lamp. Figure 7 Fig. shows the schematic view of the structure when the LED lamp is a downlight. Refer to Figure 1 and Figure 7 The LED lamp includes a lamp housing assembly 4, a light source assembly 1, a heat dissipation cover 2, and a communication assembly 3. The light source assembly 1, the heat dissipation cover 2, and the communication assembly 3 are all disposed inside the lamp housing assembly 4. The lamp housing assembly 4 can isolate the internal components of the LED lamp from the outside world, avoiding the influence of changes in outside air or moisture on the operation of the internal components, and at the same time preventing users from directly contacting the internal components of the LED lamp and causing electric shock and other accidents.

[0048] Among them, the light source assembly 1 includes a power board 11 and a light emitting member 12 that are electrically connected. The power board 11 can provide electrical energy for the light emitting member 12 to make the light emitting member 12 emit light for illumination. The inside of the heat dissipation cover 2 is hollow and has an opening. The power board 11 is disposed inside the heat dissipation cover 2, and the light emitting member 12 is connected to the periphery of the opening of the heat dissipation cover 2. Through the heat dissipation cover 2, heat can be dissipated for the power board 11 and the light emitting member 12 to ensure the normal use of the LED lamp.

[0049] It can be understood that a thermally 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 inside the heat dissipation cover 2 and the rapid conduction of the temperature of the heat dissipation cover 2 to the power board 11.

[0050] As Figure 1 shown, the light emitting member 12 includes a panel 121 and a plurality of LED light sources 122. The plurality of LED light sources 122 are arranged in an array and are disposed on the side of the panel 121 facing away from the heat dissipation cover 2. The 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 can also be a rectangular plate, and the plurality of LED light sources 122 can also be arranged in a rectangular or other polygonal shape, which is not limited herein.

[0051] Furthermore, continue to refer to Figures 1 - 3 、Figure 5 and Figure 7 The heat sink 2 has a conductive function. A through hole 21 is formed on one side of the housing of the heat sink 2 opposite to the power supply board 11. The communication component 3 is disposed in the through hole 21. 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. The first connection terminal 311 and the second connection terminal 321 are respectively electrically connected to the power supply board 11. That is to say, the second connection terminal 321 serves as a radiation element, the first connection terminal 311 serves as a ground terminal, and the power supply board 11 serves as a feeding unit. After being powered on, a current loop can be formed between the first connection terminal 311, the heat sink 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 supply board 11, thereby ensuring the communication performance of the LED lamp. Moreover, by integrating the communication structure on the heat sink 2, the antenna does not need to be placed on the lamp board, effectively saving 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 sink 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 sink 2 is preferably a metal heat sink, such as an aluminum heat sink. Other heat sinks made of materials that can both conduct electricity and conduct heat, such as conductive ceramics, graphene or conductive polymers, are also acceptable and are not limited herein. Therefore, lamps with a heat sink structure made of materials that can both conduct electricity and conduct heat inside are within the protection scope of this application.

[0053] Specifically, as Figures 4 - 6 and Figure 8 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 the first connection terminal 311; one end of the second connection portion 32 extends into the through hole 21 to form the second connection terminal 321, and the first connection portion 31 and the second connection portion 32 are arranged at intervals along the circumferential direction of the through hole 21. That is to say, the second connection portion 32 can be an L-shaped structure (refer to Figure 4 ), or a straight-shaped structure (refer to Figure 6 ), as long as it is ensured 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 a PIFA antenna after being powered on.

[0054] In this embodiment, the first connecting portion 31 and the heat dissipation cover 2 are integrally formed, and the second connecting portion 32 and the heat dissipation cover 2 are integrally formed. Both the first connecting portion 31 and the second connecting portion 32 are formed by stamping on the cover body of the heat dissipation cover 2. The first connecting portion 31 and the second connecting portion 32 are integrated with the heat dissipation cover 2, saving antenna materials, optimizing costs, simplifying production and assembly steps, and improving processing efficiency.

[0055] More specifically, the included angle between the connection line between the first connection terminal 311 and the second connection terminal 321 and the vertical direction is less than 90°. Both the first connection terminal 311 and the second connection terminal 321 are located within 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, as Figure 4 and Figure 6 shown, the connection line between the first connection terminal 311 and the second connection terminal 321 is parallel to the vertical direction. With this setting, it is not only convenient for processing and manufacturing, but also has a high aesthetic degree of styling.

[0057] More specifically, in this embodiment, the first connection terminal 311 is electrically connected to the ground wire of the power supply board 11, and the second connection terminal 321 is electrically connected to the core wire of the power supply board 11. In the above setting, the power supply board 11 serves as a feeding network, the second connection terminal 321 serves as a radiation element, and the first connection terminal 311 serves as a ground plane, forming the basic structure of a PIFA antenna. The working principle of a PIFA antenna is to transmit electromagnetic energy to the radiation element through the feeding network, and then the radiation element radiates energy in the form of electromagnetic waves; the role of the ground plane is to form a reflection, reflecting the electromagnetic waves generated by the radiation element back into 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, both the concealed design of the antenna is realized and the internal space of the LED lamp is effectively simplified. At the same time, for other lamps containing a metal radiator (or the material of the radiator can simultaneously achieve the functions of conducting electricity and dissipating heat), the antenna structure design provided in this embodiment can be adopted, making the antenna solution simpler and more cost-effective.

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

[0060] Specifically, the lamp head 42 and the housing 41 can be connected and fixed by means such as threaded connection, and no specific limitation is made here.

[0061] Optionally, the lamp housing assembly 4 further includes a light-transmitting cover 43. The light-transmitting cover 43 is connected to the end of the housing 41 away from the lamp head 42 and covers the light-emitting component 12. The setting of the light-transmitting cover 43 can converge the light generated by the light-emitting component 12 and improve the light brightness of the LED lamp. And the light-transmitting cover 43 isolates the internal components of the LED lamp from the outside world, avoiding the influence of changes in the outside air or moisture on the operation of the internal components, and at the same time preventing 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 part 44. The metal part 44 is arranged at the end of the lamp head 42 away from the housing 41, and the bottom of the metal part 44 contacts the external power supply. For example, the external power supply is a mains wire. The mains wire is introduced into the lamp head 42 through one end of the lamp head 42 close to the metal part 44. At this time, the metal part 44 is screwed to connect and fix the metal part 44 to the lamp head 42, so that the mains wire can stably supply power to the lamp of the LED lamp.

[0063] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
