Description

Technical Field

[0001] The utility model belongs to the technical field of downlights, and particularly relates to a downlight with a moisture-proof gasket. Background Art

[0002] Downlights are lamps with a screw-type lamp holder that can be directly installed with incandescent lamps or energy-saving lamps. Downlights are a type of lighting fixture that is embedded in the ceiling and emits light downward.

[0003] The existing downlight includes a lamp holder shell, electrical components, spring clips and a lampshade shell. The lamp holder shell is connected to the lampshade shell to contain the internal electrical components, and then a hole is opened on the ceiling to install the downlight in the hole and fix it with the spring clip to complete the installation and use.

[0004] As a common lighting device, downlights are widely used in home, commercial and industrial fields. However, in humid environments, such as bathrooms and basements, traditional downlights are easily damaged by moisture, which can damage the internal components of the lamps and even cause safety problems such as short circuits.

[0005] Although some designs have introduced moisture-proof gaskets to prevent moisture ingress, these gaskets often only serve as simple physical barriers and cannot cope with long-term humidity changes and complex installation environments.

[0006] To this end, we proposed a downlight with a moisture-proof gasket, which not only enables the downlight body to be installed in a humid environment, but also can effectively cope with long-term humidity changes and complex installation environments, significantly improving the stability and service life of the lamp. Utility Model Content

[0007] The purpose of the present invention is to provide a downlight with a moisture-proof gasket, which not only enables the downlight body to be installed in a humid environment, but also can effectively cope with long-term humidity changes and complex installation environments, thereby significantly improving the stability and service life of the lamp.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A downlight with a moisture-proof gasket comprises a ceiling and a downlight body, wherein a mounting hole is provided on the ceiling, a moisture-proof gasket is provided on the inner wall of the mounting hole, and the moisture-proof gasket is provided at a connection gap of the downlight body;

[0010] The moisture-proof gasket comprises a waterproof and breathable layer, a moisture-absorbing and quick-drying layer and a sealing layer. The moisture-absorbing and quick-drying layer is arranged on the inner wall of the waterproof and breathable layer, and the sealing layer is arranged on the inner wall of the moisture-absorbing and quick-drying layer.

[0011] Furthermore, the diameter of the moisture-proof gasket is the same as the diameter of the mounting hole.

[0012] Furthermore, the moisture-absorbing quick-drying layer is filled with a desiccant.

[0013] Furthermore, a first ventilation hole is provided on the inner wall of the waterproof and breathable layer, and a second ventilation hole is provided on the outer side of the moisture-absorbing and quick-drying layer.

[0014] Furthermore, the first ventilation hole and the second ventilation hole are connected to each other.

[0015] Furthermore, the downlight body comprises a lamp holder shell, electrical components and a lamp shade shell, the electrical components are installed inside the lamp holder shell and the lamp shade shell, and the lamp holder shell and the lamp shade shell are connected via threads.

[0016] The technical effects achieved by this utility model are:

[0017] The moisture-proof gasket is arranged at the connection gap of the downlight body, so as to prevent moisture from entering the interior of the downlight body through the connection gap. The waterproof gasket can allow air circulation through the waterproof and breathable outer layer when working, while preventing moisture from passing through. It has excellent waterproof performance, but allows water vapor to pass through, thereby avoiding the accumulation of condensed water caused by temperature difference, and the generated water vapor enters the moisture absorption and quick-drying layer. The moisture absorption and quick-drying layer can quickly absorb the moisture inside the gasket and keep the gasket dry. It has good hygroscopicity and quick drying properties, can quickly absorb the moisture in the water vapor, and the absorbed air is discharged through the waterproof and breathable layer. The sealing layer is located in the inner layer and fits with the connection gap of the downlight body to form an effective sealing barrier to prevent water and water vapor from entering the interior of the downlight. The device not only enables the downlight body to be installed in a humid environment, but also can effectively cope with long-term humidity changes and complex installation environments, significantly improving the stability and service life of the lamp.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0025] like Figure 1-4 As shown, the technical solution adopted by the utility model is as follows: a downlight with a moisture-proof gasket 4, comprising a ceiling 1 and a downlight body 2, a mounting hole 3 is opened on the ceiling 1, a moisture-proof gasket 4 is arranged on the inner wall of the mounting hole 3, and the moisture-proof gasket 4 is arranged at the connection gap of the downlight body 2;

[0026] The moisture-proof gasket 4 comprises a waterproof and breathable layer 5, a moisture-absorbing and quick-drying layer 6 and a sealing layer 7. The moisture-absorbing and quick-drying layer 6 is arranged on the inner wall of the waterproof and breathable layer 5, and the sealing layer 7 is arranged on the inner wall of the moisture-absorbing and quick-drying layer 6.

[0027] Its working principle is as follows: first, a mounting plate is provided on the ceiling 1, and then a moisture-proof gasket 4 is arranged at the connection gap of the downlight body 2, so as to prevent moisture from entering the interior of the downlight body 2 through the connection gap. When the waterproof gasket is working, it can allow air to circulate through the waterproof and breathable outer layer, while preventing moisture from passing through. It has excellent waterproof performance, but allows water vapor to pass through, thereby avoiding the accumulation of condensed water caused by temperature difference, and generating water vapor to enter the moisture absorption and quick-drying layer 6. The moisture absorption and quick-drying layer 6 can quickly absorb moisture inside the gasket and keep the gasket dry. It has good hygroscopicity and quick-drying properties, can quickly absorb moisture in water vapor, and the absorbed air is discharged through the waterproof and breathable layer 5. The sealing layer 7 is located in the inner layer, and fits with the connection gap of the downlight body 2 to form an effective sealing barrier to prevent water and water vapor from entering the interior of the downlight. The device not only enables the downlight body 2 to be installed in a humid environment, but also can effectively cope with long-term humidity changes and complex installation environments, significantly improving the stability and service life of the lamp.

[0028] The diameter of the moisture-proof gasket 4 is the same as the diameter of the mounting hole 3. This has the advantage that the moisture-proof gasket 4 can seal the mounting hole 3 to prevent moisture and water vapor from entering the top of the ceiling 1 through the mounting hole 3 and damaging the electrical components of the downlight body 2.

[0029] At the same time, a spring buckle (not shown in the figure) is arranged on the outer side of the downlight body 2 of the utility model, and the downlight body 2 can be fixed on the ceiling 1 through the spring buckle, which belongs to the prior art and will not be described in detail here.

[0030] In this embodiment, the material of the waterproof and breathable layer 5 is EPTFE waterproof and breathable membrane, which is a more advanced material that can effectively waterproof and maintain good breathability, making it more comfortable to wear.

[0031] In the utility model, moisture and water vapor enter the waterproof breathable layer 5, the moisture is isolated from the outside, the water vapor enters the waterproof breathable layer 5, and then enters the moisture absorbing quick-drying layer 6 to absorb the water vapor and moisture, and then the air without moisture is discharged again through the waterproof breathable layer 5. The advantage of this arrangement is that it can avoid the accumulation of condensed water caused by temperature difference, thereby being able to cope with long-term humidity changes and complex installation environments.

[0032] The material of the moisture absorption and quick-drying layer 6 is a high molecular material with excellent moisture absorption and quick-drying properties, such as polyacrylate, polyurethane, etc. These materials can effectively absorb and quickly evaporate moisture to prevent moisture from staying in the moisture-proof gasket 4.

[0033] The moisture-absorbing quick-drying layer 6 can be filled with a desiccant to improve the moisture-proof effect. The desiccant can be a common silica gel desiccant and a molecular sieve desiccant, which can quickly absorb the moisture inside the water vapor and discharge the air.

[0034] The sealing layer 7 is located in the inner layer and fits tightly with the connection gap of the downlight body 2 to form an effective sealing barrier. The sealing layer 7 is made of a highly elastic and water-resistant material, such as silicone or rubber, to ensure a long-term stable sealing effect.

[0035] In order to allow water vapor to quickly enter the moisture absorbing and quick-drying layer 6, a first ventilation hole 8 is opened on the inner wall of the waterproof and breathable layer 5, and a second ventilation hole 9 is opened on the outer side of the moisture absorbing and quick-drying layer 6. The first ventilation hole 8 and the second ventilation hole 9 can promote air circulation inside the gasket, thereby further improving the moisture-proof performance.

[0036] The first vent hole 8 and the second vent hole 9 are connected to each other, so that water vapor and air can flow quickly.

[0037] In summary, the downlight body 2 of the utility model can be easily installed in a humid environment and provide a stable and uniform lighting effect. At the same time, its unique moisture-proof gasket 4 design enables the lamp to effectively cope with long-term humidity changes and complex installation environments, significantly improving the stability and service life of the lamp.

[0038] The downlight body 2 includes a lamp holder shell, internal electrical components and a lampshade shell. The internal electrical components are installed inside the lamp holder shell and the lampshade shell. The lamp holder shell and the lampshade shell are connected by threads, and the threaded connection further seals the connection gap.

[0039] The working principle of the utility model is as follows: firstly, a mounting plate is provided on the ceiling 1, and then the moisture-proof gasket 4 is arranged at the connection gap of the downlight body 2, so as to prevent moisture from entering the interior of the downlight body 2 through the connection gap. When the waterproof gasket is working, it can allow air circulation through the waterproof and breathable outer layer, while preventing moisture from passing through. It has excellent waterproof performance, but allows water vapor to pass through, thereby avoiding the accumulation of condensed water caused by temperature difference, and generating water vapor to enter the moisture absorption and quick-drying layer 6. The moisture absorption and quick-drying layer 6 can quickly absorb moisture inside the gasket and keep the gasket dry. It has good hygroscopicity and quick-drying properties, can quickly absorb moisture in water vapor, and the absorbed air is discharged through the waterproof and breathable layer 5. The sealing layer 7 is located in the inner layer, and fits with the connection gap of the downlight body 2 to form an effective sealing barrier to prevent water and water vapor from entering the interior of the downlight. The device can not only enable the downlight body 2 to be installed in a humid environment, but also effectively cope with long-term humidity changes and complex installation environments, significantly improving the stability and service life of the lamp.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
