[0002] LEDs have advantages such as small size, long lifespan, high luminous efficacy, low heat generation, no radiation, low energy consumption, and being environmentally friendly and mercury-free, and are widely used in lighting equipment.
[0003] Existing LED lighting fixtures typically consist of LED chips installed inside the fixture housing, with heat dissipation achieved through a metal heat sink. However, this heat dissipation method presents challenges. If the metal heat sink is placed inside the fixture housing, the requirements for its molding structure are too high, resulting in high manufacturing costs and poor heat dissipation performance. If the metal heat sink is placed outside the fixture housing, it can interfere with antenna signals, and furthermore, an externally mounted metal heat sink poses a safety hazard, increasing the risk of burns.
[0004] Therefore, there is an urgent need for an LED lighting fixture to solve the above problems. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0044] This embodiment provides an LED lamp that can communicate with a smart control device to achieve intelligent adjustment of color, brightness, color temperature, etc. The smart control device can be a mobile phone, tablet computer, computer, or other device with computing and network connectivity capabilities; no specific limitation is made here. In other embodiments, the LED lamp can also be controlled by a switching device to adjust color, brightness, color temperature, etc. The LED lamp can be, but is not limited to, a bulb or downlight structure. Figure 1 and Figure 2 As shown, in this embodiment, the LED lamp is described as a bulb lamp.
[0045] Reference Figure 2 and Figure 3 The LED lamp includes a lamp housing assembly 1, a light source assembly 2, a heat sink 3, and a communication component 4. The light source assembly 2, heat sink 3, and communication component 4 are all housed within the lamp housing assembly 1. The lamp housing assembly 1 isolates the internal components of the LED lamp from the external environment, preventing changes in external air or humidity from affecting the operation of the internal components. It also prevents users from directly contacting the internal components of the LED lamp, thus avoiding accidents such as electric shock and improving safety.
[0046] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the lamp housing assembly 1 includes a housing 11. The housing 11 is hollow and has an opening 111. The housing 11 includes a hollow cavity for accommodating other components of the LED lamp. The light source assembly 2 includes a power board 22 and a light source board 21 that are electrically connected. The power board 22 is disposed within the hollow cavity of the housing 11, and the light source board 21 is connected to the periphery of the opening 111 of the housing 11. The power board 22 can provide electrical power to the light source board 21, enabling the light source board 21 to emit light for illumination.
[0047] Optionally, the inner wall of the opening 111 of the housing 11 is provided with a mounting boss 113, which is arranged along the entire circumference of the opening 111. The periphery of the light source plate 21 is placed against the mounting boss 113 and fixed by applying glue, thereby effectively improving the installation stability of the light source plate 21 and sealing the opening 111 of the housing 11 to a certain extent.
[0048] Alternatively, refer to Figure 3 and Figure 5 The inner wall of the housing 11 is provided with a slot 112, and the edge of the power board 22 is inserted and fixed in the slot 112. The slot 112 is specifically located at the bottom of the housing 11 on the side away from the opening 111, and is formed by two spaced-apart inserts. The edge of the power board 22 can be inserted between the two inserts, thereby securing the power board 22. The slot 112 allows the power board 22 to be accurately positioned with the housing 11 and quickly installed inside the housing 11, increasing the ease of installation of the LED light fixture.
[0049] Furthermore, a thermally conductive adhesive fixing layer is filled between the housing 11 and the power board 22. The thermally conductive adhesive fixing layer can quickly conduct the temperature inside the power board 22 to the housing 11, increasing the heat dissipation efficiency. At the same time, the thermally conductive adhesive fixing layer can also ensure the stability of the positioning of the power board 22 within the housing 11.
[0050] In this embodiment, the light source board 21 includes a panel and multiple LED light sources arranged in an array on the panel. Multiple independent LED light sources can form a single high-brightness light-emitting surface, and the array arrangement makes the light emitted by the LED lamp more uniform in terms of brightness. For example, the panel is a circular plate, and the multiple LED light sources are evenly arranged in a circular array. Of course, in other embodiments, the panel can also be a rectangular plate, and the multiple LED light sources can also be arranged in a rectangular or other polygonal shape; the specific arrangement can be chosen according to the shape of the LED lamp, and is not limited here.
[0051] Preferably, the power board 22 is a PCBA board. The manufacturing process of PCBA boards is highly standardized, and maintenance is convenient, effectively reducing maintenance costs and time.
[0052] Continue to refer to Figure 2 and Figure 3 The power board 22 and the light source board 21 are electrically connected via mating terminals 23. The mating terminals 23 offer high connection reliability and are small in size, minimizing space usage and contributing to a smaller overall size, making them particularly suitable for space-constrained applications. Furthermore, compared to other types of connectors, the mating terminals 23 are relatively inexpensive. In addition, their simple connection process effectively saves time and labor costs.
[0053] More specifically, such as Figure 3 and Figure 5 As shown, the lamp housing assembly 1 also includes a cover 12. The cover 12 is fastened to the opening 111 of the housing 11 and covers the light source plate 21. The cover 12 is preferably a light-transmitting cover, which can concentrate the light generated by the light source plate 21 and improve the brightness of the LED lamp. At the same time, the cover 12 fastens to the housing 11 and can seal the hollow cavity of the housing 11, so as to better protect the components inside the lamp housing assembly 1.
[0054] Optionally, a locking block 114 protrudes from the inner wall of the opening 111 of the housing 11, and a locking groove 121 corresponding to the locking block 114 is provided on the outer wall surface of the bottom of the cover 12. The locking block 114 engages with the locking groove 121, thereby realizing a detachable connection between the cover 12 and the housing 11. In this embodiment, the locking block 114 protrudes from the entire circumference of the inner wall of the opening 111 of the housing 11, and the locking groove 121 is correspondingly opened on the circumference of the outer wall surface of the bottom of the cover 12, thereby effectively improving the reliability and firmness of the connection between the cover 12 and the housing 11. Of course, in other embodiments, multiple locking blocks 114 can also be provided, with multiple locking blocks 114 arranged at intervals along the circumference of the inner wall of the opening 111 of the housing 11, and multiple locking grooves 121 correspondingly provided. The locking block 114 engages with the locking groove 121, which can also realize the connection between the cover 12 and the housing 11.
[0055] More specifically, refer to Figure 2 and Figure 3 The lamp housing assembly 1 also includes a lamp holder 13. The lamp holder 13 is connected to one end of the housing 11 away from the opening 111 and is electrically connected to the power board 22. The lamp holder 13 is the end of the LED lamp and is the connection part to the external power supply. Since the power board 22 is also electrically connected to the light source board 21, the LED lamp can generate light from the light source board 21 by connecting to the power supply through the lamp holder 13.
[0056] Furthermore, the lamp housing assembly 1 also includes a metal component 14, which is disposed at the end of the lamp holder 13 away from the housing 11, and the bottom of the metal component 14 is in contact with an external power source. For example, the external power source is an indoor power line, which is introduced into the lamp holder 13 through the end of the lamp holder 13 near the metal component 14. At this time, screwing the metal component 14 connects and fixes the metal component 14 to the lamp holder 13, thereby enabling the indoor power line to stably supply power to the LED lamp.
[0057] like Figures 2-4As shown, the heat sink 3 includes a heat sink body 31 and a heat sink 32. The heat sink body 31 is sleeved on the power board 22 and fixed to the side of the light source board 21 facing the hollow cavity of the housing 11. The heat sink body 31 is in direct contact with the light source board 21, enabling rapid heat transfer from the light source board 21. The heat sink 32 is located on the side of the heat sink body 31 away from the power board 22 and extends in a direction away from the power board 22. The heat sink 32 can transfer heat from the heat sink body 31 to a direction away from the power board 22. The design of the heat sink 32 also increases the contact area with the air, that is, increases the heat dissipation area, which is beneficial to improving heat dissipation efficiency.
[0058] Specifically, the heat sink 32 is connected to the heat sink body 31 at an angle, and the heat sink 32 is also set at an angle to the light source plate 21. The heat sink 32 abuts against the side of the light source plate 21 opposite to the opening 111. In this embodiment, the heat sink 32 is perpendicular to the light source plate 21, and also perpendicular to the sidewall of the heat sink body 31 along its length, extending to both sides of the heat sink body 31. With this configuration, part of the heat generated on the light source plate 21 can be directly transferred to the heat sink 32 for heat dissipation; the other part of the heat is first transferred to the heat sink body 31, and then dissipated through the heat sink body 31 and the heat sink 32. Of course, in other embodiments, the heat sink 32 and the heat sink body 31, and the heat sink 32 and the light source plate 21 can be set at other angles, as long as heat transfer on the light source plate 21 can be achieved; this is not limited here.
[0059] More specifically, a connecting hole is provided through the light source plate 21, and a corresponding mounting hole 33 is provided on the heat sink body 31. After the fastener 5 passes through the connecting hole, it is threadedly connected to the mounting hole 33, thereby pressing the light source plate 21 onto the heat sink body 31. For example, the fastener 5 can be a screw or bolt, etc.
[0060] Optionally, multiple heat sinks 32 are provided, which are parallel and spaced apart. The design of multiple heat sinks 32 can further increase the heat dissipation area, and heat dissipation channels can be formed between two connected heat sinks 32, which helps air circulation and heat dissipation.
[0061] It is understandable that the heat sink 31 and the heat sink 32 are integrally molded to facilitate processing and manufacturing and to improve the overall structural strength.
[0062] Meanwhile, the heat sink 3 is made of metal, preferably aluminum, which has good thermal conductivity and is lightweight, thus helping to achieve the lightweight design of the LED lamp.
[0063] Continue to refer to Figure 2 and Figure 3The communication component 4 is mounted on the power board 22. The communication component 4 passes through the heat sink 3 and the light source board 21 in sequence and protrudes from the light source board 21. This arrangement helps to reduce the shielding effect of the heat sink 3 on the communication component 4, resulting in less interference from the heat sink 3 to the communication component 4 and better signal transmission.
[0064] Specifically, a clearance hole 211 is provided on the light source board 21. One end of the communication component 4 is connected to the power supply board 22, and the other end of the communication component 4 passes through and extends out of the clearance hole 211. The opening of the clearance hole 211 is directly opposite to the inner hole of the rectangular frame of the heat sink 3. One end of the communication component 4 is connected to the edge of the contact point between the power supply board 22 and the light source board 21, and the other end of the communication component 4 passes through the clearance hole 211 to facilitate communication with external devices.
[0065] In this embodiment, the communication component 4 is a spring antenna. Spring antennas have advantages such as low cost, small size, easy installation, and strong vibration and aging resistance.
[0066] In other words, the LED lamp can quickly dissipate the heat generated by the light source board 21 during use through the structure described in this application, and the heat dissipation component 3 has less interference with the communication component 4, resulting in better communication performance of the LED lamp.
[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
