Description

[Technical Field] This utility model relates to the field of lighting equipment technology, specifically to an integrally injection-molded waterproof lamp. Background Technology Currently, most waterproof lights on the market use a simple waterproof structure that relies on sealing rings or direct glue application, which has obvious design flaws: 1. Low sealing reliability: When relying on sealing rings, gaps are prone to appear due to aging and deformation after long-term use; when applying glue directly, local leakage may occur due to uneven application and inaccurate quantity control, making it impossible to form a stable sealing layer.

[0003] 2. Pressure imbalance leading to seal failure: During use, the lamp body will generate temperature differences due to the heat generated by the circuit. The internal air expands when heated and contracts when cooled. However, the existing structure lacks a pressure regulation channel. The pressure difference will continuously squeeze the sealing layer, accelerate the deformation of the sealing ring or the cracking of the glue, and ultimately destroy the waterproof effect.

[0004] 3. Simple venting structure is prone to water ingress: Although some waterproof lights attempt to set up vents, most of them are straight holes. External moisture and water droplets can easily seep into the lamp body with airflow or gravity, failing to meet the dual requirements of venting and waterproofing. [Utility Model Content] This invention overcomes the shortcomings of the prior art and provides an integrally injection-molded waterproof lamp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A one-piece injection-molded waterproof lamp is characterized by comprising a light-transmitting plate, a light-emitting circuit assembly, and a one-piece injection-molded lamp body. The lamp body has an upper-opening mounting cavity, the light-emitting circuit assembly is disposed in the mounting cavity, a step is provided at the opening end of the mounting cavity, a step groove for accommodating adhesive is provided on the upper side of the step, the light-transmitting plate is disposed on the step and the light-transmitting plate is connected to the step by adhesive, and the lamp body has at least one vent hole, the vent hole comprising a first vent hole portion and a second vent hole portion, the diameter of the first vent hole portion being in the range of 50-200nm, and the length of the second vent hole portion being not less than 2cm.

[0007] The one-piece injection molded waterproof lamp described above is characterized in that: the vent is located in the middle of the side of the lamp body.

[0008] The one-piece injection molded waterproof lamp described above is characterized in that: the lamp body is provided with a wire outlet groove, and the groove depth ranges from 1 to 1.8 mm.

[0009] The one-piece injection molded waterproof lamp described above is characterized in that: the wire outlet groove is located at the bottom of the lamp body near the side.

[0010] The one-piece injection molded waterproof lamp described above is characterized in that: a stepped groove is provided around the upper side of the step.

[0011] The one-piece injection molded waterproof lamp described above is characterized in that: the groove depth of the stepped groove ranges from 0.8 to 1.5 mm, and the groove width of the stepped groove ranges from 1.2 to 2 mm.

[0012] The one-piece injection molded waterproof lamp described above is characterized in that: the upper opening of the mounting cavity is provided on the side of the step above the side with multiple positioning protrusions that cooperate with the light-transmitting plate.

[0013] The one-piece injection molded waterproof lamp described above is characterized in that: the upper opening of the mounting cavity is inclined.

[0014] The one-piece injection molded waterproof lamp described above is characterized in that: the step is inclinedly set at the upper opening position of the mounting cavity.

[0015] The beneficial effects of this utility model are: 1. This utility model has triple protection for more thorough waterproofing: the one-piece injection molded lamp body has no splicing gaps, the glue tank is sealed with constant volume, and the superimposed extended straw-type nano exhaust hole is designed to prevent water ingress, thus structurally blocking all water vapor infiltration paths.

[0016] 2. This utility model has a self-balancing function for air pressure, doubling the sealing life: the nano-vent can release the air pressure difference generated by the temperature difference in real time, avoiding the sealing layer from being squeezed and damaged, and can also lock in external moisture by lengthening the path and internal friction, thus taking into account both venting and waterproofing functions.

[0017] 3. This utility model has low cost and high adaptability: it does not require the addition of complex waterproof valves or breathable membranes, and achieves high-performance waterproofing only through structural optimization. It has low production difficulty and controllable cost, and is suitable for various outdoor and humid environment lighting needs. [Attached Figure Description] Figure 1 This is a schematic diagram of Embodiment 1 of the present utility model; Figure 2 This is one of the exploded views of Embodiment 1 of this utility model; Figure 3 This is the second exploded view of Embodiment 2 of the present utility model; Figure 4 This is a schematic diagram of Embodiment 2 of the present invention; Figure 5 This is a schematic diagram of Embodiment 3 of the present utility model. Detailed Implementation] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0021] like Figure 1-3 As shown, a one-piece injection-molded waterproof lamp includes a light-transmitting plate 1, a light-emitting circuit assembly, and a one-piece injection-molded lamp body 2. The one-piece injection-molded lamp body 2 eliminates any seams.

[0022] The lamp body 2 has a mounting cavity 21 with an opening at the top. The light-emitting circuit assembly is placed inside the mounting cavity 21. A step 22 is provided at the opening end of the mounting cavity 21. A stepped groove 23 for accommodating adhesive is provided on the upper side of the step 22. The light-transmitting plate 1 is placed on the step 22 and is connected to the step 22 by adhesive. The groove depth of the stepped groove 23 ranges from 0.8 to 1.5 mm, and the groove width ranges from 1.2 to 2 mm. This allows for precise accommodating and settling of waterproof adhesive. After the light-transmitting plate 1 is closed, the adhesive evenly fills the space inside the groove, forming a continuous and thick annular sealing layer, avoiding the unevenness problem of traditional direct pasting.

[0023] The lamp body 2 is provided with at least one exhaust hole 24, which includes a first exhaust hole section as a nano-sized pore size segment and a second exhaust hole section as an extended straw-like path segment. The pore size of the first exhaust hole section as a nano-sized pore size segment is in the range of 50-200nm, ensuring that only air molecules are allowed to pass through; the length of the second exhaust hole section as an extended straw-like path segment is not less than 2cm, which extends the airflow path and uses internal friction to block external water vapor and water droplets from entering with the airflow, thus achieving the function of venting without water entering.

[0024] The lamp body 2 is provided with a wire outlet groove 25. The groove depth of the wire outlet groove 25 ranges from 1 to 1.8 mm. The groove width matches the wire diameter. Waterproof glue can be specifically filled in the wire outlet groove to completely cover the gap between the wire and the lamp body, solving the problem of weak sealing at the traditional wire outlet.

[0025] like Figure 1-3As shown, the stepped groove 23 is arranged around the upper side of the step 22, which allows the glue to fill the space inside the groove evenly, forming a continuous and thick annular sealing layer; the vent 24 is arranged in the middle of the side of the lamp body 2, which can better realize the venting and prevent water from entering; the wire outlet groove 25 is arranged at the bottom of the lamp body 2 near the side, corresponding to the wire outlet of the light-emitting circuit component, which facilitates the wire outlet of the light-emitting circuit component.

[0026] like Figure 4 As shown, the upper opening of the mounting cavity 21 is located on the side above the step 22 and has multiple positioning protrusions 26 that cooperate with the light-transmitting plate 1 to prevent displacement during the adhesive bonding process.

[0027] like Figure 1 and Figure 5 As shown, the upper opening of the mounting cavity 21 is inclined; the step 22 is inclined at the upper opening of the mounting cavity 21. It can be inclined according to actual use requirements, thereby changing the light output direction and improving the overall aesthetics.

[0028] This case is applicable to scenarios such as outdoor courtyards, bathrooms, and underground garages that are damp, have large temperature fluctuations, and are prone to water accumulation.

[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
