[0030] The serial numbers assigned to components in this article, such as "first" and "second", are used only to distinguish the objects being described and have no sequential or technical meaning.

[0031] Tri-proof lights are lighting fixtures with dustproof, waterproof, and corrosion-resistant functions, typically used in harsh environments. Dustproof protection prevents dust, powder, and other fine particles from entering the fixture; waterproof protection prevents rainwater, humid air, or other liquids from damaging the interior; and corrosion resistance means the fixture is made of corrosion-resistant materials, such as a corrosion-resistant shell and special coatings, making it resistant to chemical substances, acids, alkalis, and other harmful gases. To achieve these benefits, tri-proof lights are usually made with special sealing structures and materials. Once assembled, it is difficult to adjust the lighting parameters; usually, the entire fixture must be disassembled to adjust parameters such as power and color temperature. This inconvenience can compromise the protective performance of the tri-proof light.

[0032] To address the aforementioned problems, this application provides an LED lighting fixture, please refer to... Figures 1 to 3 As shown, the LED light fixture includes:

[0033] The housing assembly 1 includes a lamp housing 2 and a lamp shade 3 arranged opposite to each other. The lamp housing 2 and the lamp shade 3 are fixedly connected and enclose a sealed accommodating space. The lamp housing 2 includes a housing body 21 and a sealing cover 22. The housing body 21 is provided with a connecting hole 23 that connects the accommodating space to the outside. The sealing cover 22 covers the connecting hole 23 and is detachably connected to the housing body 21.

[0034] The light source assembly is fixedly installed in the accommodating space; the light source assembly includes a light-emitting unit (not shown) and a switch unit 41, the light-emitting unit and the switch unit 41 are electrically connected, and the light emitted by the light-emitting unit is emitted outward through the lamp cover 3; the switch unit 41 is located in the accommodating space opposite to the connecting hole 23.

[0035] The LED lamp provided in this application embodiment can emit light to achieve illumination when powered on. Powering on can include powering the LED lamp with an external power supply or a built-in battery.

[0036] In the specific structure of LED lighting fixtures, to ensure product consistency and good isolation between the inside and outside of the LED lighting fixture, the internal components of the LED lighting fixture are protected to achieve a three-proof effect of dustproof, waterproof, and corrosionproof. The LED lighting fixture includes a housing assembly 1, which has a lamp housing 2 and a lamp shade 3. The lamp housing 2 and the lamp shade 3 are arranged opposite each other and fixed with connecting wires. The lamp housing 2 and the lamp shade 3 enclose a sealed accommodating space. The sealed nature means that the accommodating space is isolated from the outside world. This allows the components inside the accommodating space to achieve waterproof, dustproof, and corrosion-proof protection, thereby ensuring the reliable use of the LED lighting fixture in harsh environments and extending its service life.

[0037] In this LED lighting fixture, the lamp housing 2 and the lamp shade 3 correspond to the light-shielding and light-emitting parts, respectively. The lamp housing 2, as the light-shielding structure of the LED lighting fixture, blocks the light emitted from the non-light-emitting side of the LED, preventing light leakage. The lamp shade 3, while enclosing and forming a accommodating space, allows light emitted from the light source located inside the lamp shade 3 to pass through and be emitted outwards. For this purpose, the lamp shade 3 is made of a light-transmitting material, including light-transmitting glass or light-transmitting plastic. Since the lamp housing 2 needs to block the light emission, it is usually an opaque structure. Specifically, the lamp housing 2 can be made of an opaque material, or it can be made by applying an opaque coating to a transparent material.

[0038] The lamp housing 2 and the lamp shade 3 can be fixedly connected by means of snaps, threaded connectors, etc. At least one of the lamp shade 3 and the lamp housing 2 has a recessed structure, which allows the lamp shade 3 and the lamp housing 2 to form the required accommodating space when they are fixedly connected.

[0039] To achieve illumination, the LED luminaire also includes a light source assembly, which is disposed within an accommodating space and is directly or indirectly fixedly connected to the housing assembly 1. The light source assembly specifically comprises a light-emitting unit for emitting light and a DIP switch unit 41 for controlling the light-emitting parameters of the light-emitting unit, wherein the DIP switch unit 41 and the light-emitting unit are electrically connected. When powered on, the light emitted by the light-emitting unit can be emitted outwards through the lampshade 3, thereby achieving the purpose of illumination.

[0040] The DIP switch unit 41 can be used to control the light emission parameters of the light emission unit. In order to quickly adjust the light emission parameters, the lamp housing 2 in this embodiment includes a housing body 21 and a sealing cover 22. The housing body 21 has a connecting hole 23, which connects the two sides of the housing body 21, that is, connects the accommodating space with the outside. The sealing cover 22 is detachably connected to the housing body 21 and covers the connecting hole 23. Therefore, the sealing cover 22 can selectively close or open the connecting hole 23. When the connecting hole 23 is closed, the LED lamp is kept in a sealed state, which can maintain the three-proof performance inside the LED lamp. If the sealing cover 22 is removed from the housing body 21, the connecting hole 23 on the housing body 21 is opened. Therefore, the DIP switch unit 41 located in the accommodating space can be operated directly from the outside. The DIP switch unit 41 adjusts the light emission parameters of the light emission unit according to the operation. This allows the light emission parameters of the LED lamp to be adjusted without disassembling the entire LED lamp, which greatly improves the convenience of operation and ensures the tri-proof performance of the LED lamp.

[0041] In this embodiment, the DIP switch unit 41 may include one or more units, and different forms of DIP switch units 41 may be set according to the different light emission parameters to be adjusted. Specifically, the DIP switch unit 41 may include a color temperature control unit and / or a power control unit, wherein the color temperature control unit can be used to control the color temperature of the light emitted by the light emission unit, and the power control unit can be used to control the operating power of the light emission unit, that is, to adjust the illumination brightness of the LED lamp.

[0042] In some optional embodiments, to facilitate operation of the DIP switch unit 41, the position of the DIP switch unit 41 in this embodiment overlaps with the orthographic projection position of the connecting hole 23 along the axial direction within the accommodating space. That is, the DIP switch unit 41 is directly opposite the opening of the connecting hole 23. This allows the operator to visually see the position of the DIP switch unit 41 after removing the sealing cover 22, enabling quick operation of the DIP switch unit 41 to adjust the light emission parameters.

[0043] In some alternative embodiments, please refer to Figure 4 To further facilitate the operation of the DIP switch unit 41, the DIP switch unit 41 is fixedly disposed inside the housing body 21. The DIP switch unit 41 has an operating end 42, which is exposed outside the housing body 21 through a connecting hole 23. The connecting hole 23 on the housing body 21 allows the operator to contact the interior of the accommodating space. In this embodiment, the DIP switch unit 41 is directly disposed inside the housing body 21, and the operating end 42 of the DIP switch unit 41 is exposed through the connecting hole 23. The function of the operating end 42 is to receive user operations to realize the function of the DIP switch unit 41. Therefore, exposing the operating end 42 through the connecting hole 23 allows the user to directly operate the DIP switch unit 41 after removing the sealing cover 22. Specifically, the purpose of fixing the DIP switch unit 41 inside the housing body 21 can be achieved by providing a threaded connection structure, a snap-fit ​​structure, etc., inside the housing body 21 and the DIP switch unit 41. The operation terminal 42 on the dial unit 41 may specifically include a lever, knob, button, etc., and this embodiment does not limit it. It can be set according to the specific type of light emission parameters. For example, a knob can be set to gradually adjust the light emission color temperature; or, a multi-level lever can be set to switch between different levels of light emission power, etc.

[0044] In some alternative embodiments, please refer to Figure 5 To connect and seal the sealing cap 22 to the shell body 21, the sealing cap 22 may have a capping portion 221 and an extension portion 222 disposed opposite to each other. The extension portion 222 passes through the connecting hole 23 and forms a detachable connection with the shell body 21. The capping portion 221 covers the connecting hole 23, and the outline size of the capping portion 221 is larger than the diameter of the connecting hole 23. The extension portion 222 of the sealing cap 22 is inserted into the connecting hole 23, and the extension portion 222 and the connecting hole 23 form a connection fit, so that the extension portion 222 and the connecting hole 23 are in close contact. Since the outline of the capping portion 221 is larger than the connecting hole 23, when the extension portion 222 is inserted into the connecting hole 23, the capping portion 221 will cover the surface of the connecting hole 23, and the connecting hole 23 will be completely covered therein, avoiding the situation where the connecting hole 23 is still exposed after the sealing cap 22 is connected to the shell body 21.

[0045] In some optional embodiments, to ensure a detachable fixed connection between the sealing cap 22 and the shell body 21 while maintaining the sealing performance of the connection, the wall of the connecting hole 23 is provided with internal threads, and the outer periphery of the extension 222 is provided with external threads that match the internal threads. In other words, the sealing cap 22 and the shell body 21 are fixedly connected through the threaded engagement of the connecting hole 23 and the extension 222. The threaded engagement is characterized by both sealing and ease of disassembly and assembly. Therefore, in this embodiment, the outer periphery of the extension 222 is provided with external threads, and the wall of the connecting hole 23 is provided with corresponding internal threads, which cooperate to form a threaded connection.

[0046] In some alternative embodiments, besides connecting the sealing cap 22 to the shell body 21 via a threaded connection, the extension 222 can also connect to the shell body 21 via an interference fit with the connecting hole 23. The interference fit is a shaft-hole connection method, where the tolerance zone of the connecting hole 23 is below the tolerance zone of the extension 222, and the algebraic result of subtracting the outer diameter of the extension 222 from the diameter of the connecting hole 23 is negative. The interference fit provides a fixed connection between the extension 222 and the connecting hole 23, and allows for disassembly and reassembly via insertion and removal. Furthermore, to ensure sealing performance, the extension 222 can be made of an elastic material. When inserted into the connecting hole 23, the extension 222, based on its elasticity, can form a tight contact with the inner wall of the connecting hole 23, thereby improving the sealing effect. Applying external force can deform the extension 222, facilitating the removal of the sealing cap 22 from the shell body 21.

[0047] In some alternative embodiments, to further ensure sealing performance, the cap portion 221 and the extension portion 222 can be a one-piece molded structure. A one-piece molded structure avoids seams caused by product assembly, thereby improving sealing performance. The cap portion 221 and the extension portion 222 are a one-piece molded structure, that is, the cap portion 221 and the extension portion 222...

[0048] In some alternative embodiments, to further improve sealing performance, the LED lamp may also include an elastic sealing element 5, which is disposed around the extension 222 and located between the housing body 21 and the cover 221. In this embodiment, the elastic sealing element 5 may be a silicone sealing ring, which is disposed around the extension 222. During the process of connecting the sealing cover 22 to the housing body 21, the elastic sealing element 5 is compressed and deformed between the cover 221 and the housing body 21, thereby achieving elastic contact with the housing body 21 and the cover 221, effectively improving the sealing performance of the connection between the sealing cover 22 and the housing body 21. Specifically, the elastic sealing element may be a sealing rubber ring, which may be fixed to the housing body 21 or the sealing cover 22, or may be independently disposed between the two.

[0049] In some optional embodiments, with the sealing cover 22 provided, to make the sealing cover 22 less noticeable in use and avoid affecting the visual integrity of the LED lamp, the connecting hole 23 and the sealing cover 22 can be specifically located on the shell wall of the housing body 21 away from the lampshade 3. The shell wall of the housing body 21 away from the lampshade 3 is essentially the back side of the LED lamp's light-emitting surface, meaning that the connecting hole 23 and the sealing cover 22 are hidden relative to the light-emitting surface of the LED lamp. During daily use of the LED lamp, the presence of the sealing cover 22 is not easily noticeable, thereby improving the overall visual integrity of the LED lamp.

[0050] According to the LED lamp provided in the embodiments of this application, since the housing assembly 1 is provided with a connecting hole 23 that connects the inside and outside, the DIP switch unit 41 can be operated without damaging the assembly relationship of the LED lamp by removing the sealing cover 22, thereby greatly improving the convenience of adjusting the lighting parameters of the LED lamp.

[0051] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
