Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a waterproof garden light. Background Technology

[0002] In the field of outdoor lighting, garden lights, as common decorative lighting devices, are widely used in gardens, courtyards, parks, and other places. They not only provide necessary lighting for nighttime activities but also create a warm and beautiful outdoor atmosphere. However, because garden lights are exposed to the outdoors for a long time, they are inevitably affected by various weather conditions, especially rainwater erosion.

[0003] Traditional garden lights often have several shortcomings in their waterproof design. Firstly, many garden lights have simple housing connections, often using direct splicing or simple snap-fit ​​connections. Over time, these connections are prone to gaps due to minor loosening of components, aging, and the effects of temperature changes and vibrations in the outdoor environment. This allows rainwater to easily seep into the light fixture through the housing joints. Once moisture enters, it can damage the internal electronic components, such as bulbs, LED panels, and circuit boards. Moisture can cause short circuits, rendering the light fixture malfunction, and may even pose a fire hazard due to the high temperatures generated by the short circuit. Furthermore, moisture accelerates the oxidation and corrosion of electronic components, shortening the lifespan of the light fixture and increasing the cost of repair and replacement.

The lens is installed at the first light-emitting port of the middle housing and is located between the middle housing and the front housing. The light-emitting element is installed in the receiving cavity and emits light through the first light-emitting port and the second light-emitting port. The first sealing ring is sandwiched between the mating surfaces of the main housing and the middle housing. When the main housing and the middle housing are rotated and locked relative to each other, the mating surfaces of the two press against the first sealing ring to achieve a seal.

[0006] In some embodiments, the main housing includes a main shell and a rear shell threadedly connected to the rear end of the main shell, and the front end of the main shell is threadedly connected to the middle shell;

[0007] It also includes a second sealing ring, which is sandwiched between the mating surfaces of the main body shell and the rear shell;

[0014] In some embodiments, the connection between the rear shell, the main shell, the middle shell, and the front shell is a smooth transition.

[0015] In some embodiments, a third sealing ring is further included, sandwiched between the mating surfaces of the middle shell and the front shell;

[0016] When the middle shell and the front shell rotate and lock relative to each other, the mating surfaces of the two press against the third sealing ring to achieve a seal.

[0017] In some embodiments, the middle shell includes a third connecting portion and a fourth connecting portion connected to each other;

[0018] The inner side of the third connecting part is provided with an internal thread for threaded connection with the main body shell.

[0019] The outer side of the fourth connecting part is provided with an external thread for threaded connection with the front shell.

[0020] The outer diameter of the third connecting part is larger than the outer diameter of the fourth connecting part, and the connection between the two together defines a third annular mounting groove.

[0024] In some embodiments, the support assembly further includes a support member connected to the support frame, the support member being a grounding rod or a support base.

[0025] The waterproof garden light based on this application embodiment utilizes the compression between the housings to secure the first sealing ring. During installation, the operator simply needs to tighten each component sequentially. When installing the main housing and the middle housing, the first sealing ring is first fitted onto the outer surface of the main housing, and then the middle housing is slowly rotated to connect with the main housing via threads. As rotation continues, the mating surfaces of the main housing and the middle housing gradually compress the first sealing ring. The operator only needs to continue rotating until the tightening force feels appropriate to complete this part of the installation. Under the compression of the housings, the first sealing ring undergoes elastic deformation, simultaneously generating a reverse elastic force. This elastic force ensures a tight fit between the first sealing ring and the main housing and the middle housing, preventing any reduction in sealing effect even after prolonged use due to minor loosening of components or changes in environmental factors. This embodiment offers simple installation and reliable sealing. Attached Figure Description

[0039] Please see Figures 1 to 5 This application provides a waterproof garden light 1. The waterproof garden light 1 includes a main housing 10, a middle housing 20, a front housing 30, a lens 40, a light-emitting element 50, and a first sealing ring 61.

[0040] Please see Figure 3 and Figure 5 The middle shell 20 is threadedly connected to the front end of the main shell 10 and together with the main shell 10 defines a receiving cavity. The middle shell 20 is provided with a first light-emitting port 20a communicating with the receiving cavity. The front shell 30 is threadedly connected to the front end of the middle shell 20 and is provided with a second light-emitting port 30a corresponding to the first light-emitting port 20a. The lens 40 is installed at the first light-emitting port 20a of the middle shell 20 and is located between the middle shell 20 and the front shell 30. The light-emitting element 50 can be in the form of a bulb, LED light board, etc. It is installed in the receiving cavity and emits light outward through the first light-emitting port 20a and the second light-emitting port 30a. The first sealing ring 61 is sandwiched between the mating surfaces of the main shell 10 and the middle shell 20. When the main shell 10 and the middle shell 20 are rotated and locked relative to each other, the mating surfaces of the two press the first sealing ring 61 to achieve a seal.

[0041] Please see Figure 4 and Figure 5 In some embodiments, the main housing 10 includes a main housing 11 and a rear housing 12 threadedly connected to the rear end of the main housing 11, and the front end of the main housing 11 is threadedly connected to the middle housing 20; the waterproof garden light 1 also includes a second sealing ring 62, which is sandwiched between the mating surfaces of the main housing 11 and the rear housing 12; during the relative rotation and locking process of the main housing 11 and the rear housing 12, the mating surfaces of the two compress the second sealing ring 62 to form a seal, preventing moisture from seeping in from the connection between the main housing 11 and the rear housing 12, and further protecting the light-emitting element 50 and other components in the cavity.

[0042] Please see Figures 3 to 5In some embodiments, the main shell 11 includes a first connecting portion 111 and a second connecting portion 112 connected together; the inner surface of the first connecting portion 111 is provided with an internal thread for threaded connection with the rear shell 12; the outer surface of the second connecting portion 112 is provided with an external thread for threaded connection with the middle shell 20; wherein, the outer diameter of the first connecting portion 111 is larger than the outer diameter of the second connecting portion 112, and the connection between the two together defines a first annular mounting groove 113, and a first sealing ring 61 is sleeved on the outer surface of the second connecting portion 112 and embedded in the first annular mounting groove 113. When the main shell 10 and the middle shell 20 are rotated and locked relative to each other, the mating surfaces of the two tightly press the first sealing ring 61, causing it to undergo elastic deformation and fill the tiny gaps between the mating surfaces, thereby preventing moisture from entering the receiving cavity from the connection between the main shell 10 and the middle shell 20.

[0043] The inner side of the first connecting part 111 is also provided with a second annular mounting groove 114, and the second sealing ring 62 is embedded in the second annular mounting groove 114. In this way, it is easy to install and position the second sealing ring 62 and prevent the second sealing ring 62 from being excessively displaced during use.

[0044] Please see Figure 3 and Figure 5 In some embodiments, the waterproof garden light 1 further includes a third sealing ring 63, which is sandwiched between the mating surfaces of the middle shell 20 and the front shell 30; when the middle shell 20 and the front shell 30 are rotated and locked relative to each other, the mating surfaces of the two press the third sealing ring 63 to achieve a seal.

[0045] Please see Figure 3 and Figure 5 In some embodiments, the middle shell 20 includes a third connecting portion 21 and a fourth connecting portion 22 connected to each other; the inner side of the third connecting portion 21 is provided with an internal thread for threaded connection with the main shell 11; the outer side of the fourth connecting portion 22 is provided with an external thread for threaded connection with the front shell 30; wherein, the outer diameter of the third connecting portion 21 is larger than the outer diameter of the fourth connecting portion 22, and the connection between the two defines a third annular mounting groove 23, and the third sealing ring 63 is sleeved on the outer side of the fourth connecting portion 22 and embedded in the third annular mounting groove 23.

[0046] Please see Figure 3 and Figure 5 In some embodiments, the waterproof garden light 1 further includes a fourth sealing ring 64, which is sandwiched between the middle shell 20 and the lens 40. The fourth sealing ring 64 is arranged around the edge of the first light outlet. After the middle shell 20 and the lens 40 are installed in place, the fourth sealing ring 64 is compressed to form a sealing barrier to prevent moisture from entering the receiving cavity from the contact surface between the lens 40 and the middle shell 20, thus protecting the light-emitting element 50 from water vapor corrosion.

[0047] Please see Figure 3 and Figure 5 In some embodiments, the waterproof garden light 1 further includes a fifth sealing ring 65, which is sandwiched between the lens 40 and the front housing 30. The fifth sealing ring 65 is disposed around the edge of the second light outlet and is located at the mating surface of the lens 40 and the front housing 30. During the locking process between the front housing 30 and the middle housing 20, the fifth sealing ring 65 is compressed, further enhancing the sealing effect and ensuring that moisture cannot enter the interior of the light body through the gap between the lens 40 and the front housing 30.

[0048] Based on the above embodiments, the sealing ring can be in the form of silicone, rubber, etc. Silicone has good flexibility, high temperature resistance and chemical stability, while rubber has good elasticity and wear resistance. Both can produce sufficient deformation to fill the gap when squeezed, and can maintain stable sealing performance over a wide temperature range, effectively adapting to changes in the outdoor environment.

[0049] In some embodiments, the connections between the rear shell 12, the main shell 11, the middle shell 20, and the front shell 30 are smoothly transitioned. This ensures that the outer surface of the waterproof garden light 1 has no protruding parts, resulting in smooth lines and a more aesthetically pleasing appearance. Furthermore, the sealing components are concealed between the various connection points and contact surfaces, without affecting the overall appearance of the light fixture. While achieving excellent waterproof performance, it also meets users' aesthetic needs, allowing the light fixture to better integrate into various outdoor landscape environments such as gardens and courtyards, serving a dual purpose of decoration and lighting.

[0050] The waterproof garden light 1 based on this application embodiment utilizes the compression between the housings to fix the sealing components. During installation, the operator only needs to tighten each component sequentially. For example, when installing the main housing 10 and the middle housing 20, firstly, the first sealing ring 61 is fitted onto the outer side of the second connecting part 112 of the main housing 11 and embedded in the first annular mounting groove 113. Then, the middle housing 20 is aligned with the second connecting part 112 of the main housing 11, and the middle housing 20 is slowly rotated to make it threadedly connected to the main housing 11. As the rotation proceeds, the mating surfaces of the main housing 10 and the middle housing 20 gradually compress the first sealing ring 61. The operator only needs to continue rotating until the tightening force feels appropriate to complete this part of the installation. Under the compression of the housing, the sealing component undergoes elastic deformation and generates a reverse elastic force. This elastic force can always maintain a tight fit between the sealing component and the housing, and even after long-term use, the sealing effect will not be reduced due to slight loosening of the components or changes in environmental factors. Thus, the installation is simple and the sealing effect is reliable.

[0051] This application employs a multi-layered sealing design with a first sealing ring 61, a second sealing ring 62, a third sealing ring 63, a fourth sealing ring 64, and a fifth sealing ring 65, creating an almost completely sealed space within the housing of the waterproof garden light 1. Rainwater, dew, or other forms of moisture are unlikely to enter the lamp body through the various connection points and contact surfaces, effectively protecting the electronic components installed within the housing, such as the bulb, LED panel, and circuit board. These light-emitting elements 50 can operate stably in a dry environment, significantly reducing the probability of short circuits, damage, and other malfunctions caused by moisture intrusion, extending the lifespan of the lamp, and reducing maintenance and replacement costs.

[0052] Please see Figure 1 and Figure 5 In some embodiments, the waterproof garden light 1 further includes a support assembly 70 for securely mounting the waterproof garden light 1 in different scenarios. The rear housing 12 has a mating portion 121. The support assembly 70 includes a support frame 71 with two connecting ears 711, which are positioned opposite each other and spaced apart. The mating portion 121 is located between the two connecting ears 711 and is hinged to the two connecting ears 711 by threaded fasteners 80, such as bolts and nuts. This hinged connection allows the waterproof garden light 1 to rotate at a certain angle relative to the support frame 71, thereby adjusting the direction of the light according to actual needs.

[0053] In some embodiments, the support assembly 70 further includes a support member 72 detachably connected to the support frame 71. The support member 72 can be a ground stake or a support base, which can be selected according to the actual usage scenario. Specifically, when the ground stake is connected to the support frame 71, the ground stake can be inserted into the soil of the garden, and the soil's fixing effect can be used to make the waterproof garden light 1 stand firmly on the ground, which is suitable for outdoor scenarios such as gardens and lawns. When the support base is connected to the support frame 71, the support base can be placed on a flat table, ground or other hard surface to provide stable support for the waterproof garden light 1, which is suitable for indoor or outdoor places where it is inconvenient to insert it into the ground.
