Description

Sealing member, lamp controller and outdoor lamp

Technical Field

Embodiments of the present disclosure generally relate to a sealing member, a luminaire controller including the sealing member, and an outdoor luminaire adapted to be connected with the luminaire controller.

Background

Sealing members are widely used in a variety of applications, particularly in the joints of dissimilar objects to provide a seal of the joint. A typical sealing member may be configured in a ring shape. Such annular sealing members may be used to provide a seal at the junction of a substantially cylindrical object with another object.

For example, in an outdoor light fixture, the controller mounting bosses thereof are substantially cylindrical and are pre-mounted on the outdoor light fixture. The light fixture controller is then connected to the controller mounting boss. The light fixture controller may include a sealing member, such as a sealing ring, to provide a seal between the light fixture controller and the controller mounting boss. Since the controller mounting bosses are typically provided by different suppliers, their diameters vary widely. This varying diameter makes it difficult for conventional sealing members to provide a reliable seal.

SUMMERY OF THE UTILITY MODEL

As noted above, there is a need to provide an improved sealing member that can accommodate varying diameter dimensions of the object to be sealed, thereby providing a seal in a convenient and reliable manner.

Embodiments of the present disclosure provide a sealing member, a luminaire controller comprising the sealing member, and an outdoor luminaire adapted to be connected with the luminaire controller, which aim to at least partially address the above and/or other potential problems.

In a first aspect, embodiments of the present disclosure provide a seal member. The sealing member is made of an elastic material, and includes: a body annularly shaped about an axial direction and having a first side and a second side that are axially opposite each other; a first seal ring disposed within the body about the axial direction and including a sealing surface adapted to contact a circular end surface of an object entering the body from the second side, the sealing surface being perpendicular to the axial direction; and a tapered thin wall including a first segment connecting the first seal ring to the main body over an entire circumference and inclined radially inward in a direction from the second side to the first side. In a non-mounted state, the inner diameter of the tapered thin wall on the second side is larger than the outer diameter of the circular end face, and the inner diameter of the tapered thin wall on the first side is smaller than the outer diameter of the circular end face.

According to an embodiment of the present disclosure, the sealing member made of an elastic material has a certain deformability. Specifically, during the process of the object entering the main body from the second side of the main body of the sealing member, the object may come into contact with a certain portion of the tapered thin wall, and in the subsequent entering process, the tapered thin wall is continuously pressed toward the radial outer side, so that the inner diameter of the tapered thin wall at the first side becomes larger, and the first sealing ring is further expanded toward the radial outer side. After the object is fully seated, the inner diameter of the tapered thin wall on the first side is enlarged substantially to equal the outer diameter of the circular end face of the object. In this state, the first sealing ring has a radial dimension such that its sealing surface is adapted to axially abut the outer periphery of the circular end face of the object, thereby providing a seal. In this way, the sealing member can be adapted to objects of different diameters by virtue of its own deformability, thereby improving the adaptability of the sealing member to objects of different specifications and sizes and ensuring the reliability of sealing.

Further, in practical applications, the axis of rotation of the seal member may deviate from the axis of rotation of the object (particularly, a cylindrical object) due to dimensional variations of components and/or assembly errors, and the like. The sealing member according to an embodiment of the present disclosure can also be adjusted to a position where the axis of revolution of the sealing member is aligned with the axis of revolution of the object by its own elasticity under the pressure of the object. In this way, the seal structure comprising the seal member also has a "self-centering" function, thereby ensuring that the sealing surface of the seal member can always be in accurate contact with the outer periphery of the circular end face of the object to provide a reliable seal.

In some embodiments, the first section may comprise: a first connecting portion connected to the main body at a position adjacent to the second side; and a second connection portion connected to a radially outer side wall of the first seal ring at a position adjacent to the sealing surface. In such an embodiment, on the one hand, the first section extends obliquely inwardly from a position of the body adjacent to the second side, whereby the first section has an axial dimension which is as long as possible. Such a tapered thin wall has a large elastic deformability and can therefore be adapted to a large diameter range of different objects. On the other hand, the first section is connected to the radially outer side wall of the first seal ring at a position adjacent to the sealing surface, so that after the object is fully mounted in place, the sealing surface of the sealing member can accurately contact the outer periphery of the circular end face of the object to provide a reliable seal.

In some embodiments, the tapered thin wall may further comprise: a second section arranged to extend axially away from the body from the first connection; and a second sealing ring arranged to project radially inwardly from an end of the second segment remote from the first connection, a radially inner end face of the second sealing ring being adapted to contact a side wall of the object to provide a further seal. In such embodiments, the second seal ring can contact the radially outer sidewall of the object in addition to the axial seal provided by the first seal ring to provide a radial seal. Such a double sealing structure further improves the reliability of the sealing.

In some embodiments, the sealing member may further include: at least one third seal ring projecting radially outwardly from the radially outer side wall of the body, the at least one third seal ring adapted to contact another object to provide a seal. In such embodiments, the sealing member may be mounted to another object. At least one third sealing ring may be in contact with the further object (e.g. the housing) to provide a seal against the further object itself.

In some embodiments, the sealing member may be integrally molded from a silicone rubber material. The silicone rubber material has good elasticity and is not itself invaded by moisture and dust. The integral forming process improves the production efficiency of the sealing component, and the integral forming sealing component also has better sealing effect.

In some embodiments, the body may include an annular groove recessed from the second side to an interior thereof. In such an embodiment, the seal member can be reliably mounted to other objects by means of the annular groove.

In a second aspect, embodiments of the present disclosure provide a luminaire controller. The luminaire controller comprises a sealing member according to the above first aspect. Since the lamp controller includes the sealing member as described above, the same advantageous effects as the sealing member can be provided.

In some embodiments, the light fixture controller may be an outdoor light fixture controller. The object may be a controller mounting boss of the light fitting and at least the end portion is cylindrical. In such embodiments, since the outdoor light fixture controller includes a sealing member as described above, the sealing member can be adapted to different sizes of the controller mounting bosses, thereby providing a reliable seal between the outdoor light fixture controller and the controller mounting bosses. Outdoor luminaire controllers according to embodiments of the present disclosure are particularly advantageous because their application scenarios place higher demands on the reliability of the seal.

In a third aspect, embodiments of the present disclosure provide an outdoor light fixture. The top of the outdoor lamp is provided with a cylindrical controller mounting boss which is provided with a circular end face. The circular end face is provided with mechanical and electrical interfaces and is adapted to be connected with a lamp controller according to the second aspect described above and is water and dust resistant via a sealing member as described above. Since the outdoor lamp can be protected from water and dust via the sealing member as described above, the same advantageous effects as the sealing member can be provided.

In some embodiments, the outdoor light fixture may be a street light.

Detailed Description

The present disclosure will now be described with reference to several example embodiments. It should be understood that these examples are described only for the purpose of enabling those skilled in the art to better understand and thereby enable the present disclosure, and are not intended to set forth any limitations on the scope of the technical solutions of the present disclosure.

As used herein, the term "include" and its variants are to be read as open-ended terms meaning "including, but not limited to. The term "based on" will be read as "based at least in part on". The terms "one embodiment" and "an embodiment" should be understood as "at least one embodiment". The term "another embodiment" should be understood as "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions may be included below. The definitions of the terms are consistent throughout the specification unless the context clearly dictates otherwise.

As described hereinabove, a fixed diameter sealing ring is difficult to provide a reliable seal due to the large variation in the physical dimensions of the object to be sealed (e.g., the controller mounting boss of a light fixture) (e.g., the diameter of which may vary from 63.5mm to 66.675 mm).

Sealing rings made of sponge have been proposed. Such a seal ring has a larger cross-sectional area to accommodate the varying larger outer dimensions. However, sealing rings made of sponge are easily damaged, resulting in seal failure. In addition, the sponge itself has water absorbency. External water vapor is easily absorbed by the sealing ring made of sponge and then enters the sealed space, thereby causing sealing failure. Sponge materials are also expensive.

Furthermore, sealing rings made of silicone rubber materials have also been proposed. However, since silicone rubber materials are harder than sponge materials and, accordingly, less compressible than sponge materials, such seal rings cannot be made with a larger cross-sectional area and cannot accommodate the larger variations in overall dimensions.

In order to solve the above problems, embodiments of the present disclosure provide a sealing member, a lamp controller including the sealing member, and an outdoor lamp adapted to be connected with the lamp controller. In general, a sealing member according to an embodiment of the present disclosure is made of an elastic material and has a certain elastic deformability. By means of elastic deformation, the sealing ring for providing a seal in the sealing member can be used with objects of different diameters and has a "self-centering" function. Some example embodiments of the present disclosure will be described in detail below with reference to fig. 1 to 9.

Fig. 1 to 3 show an example of a seal member 1 according to an embodiment of the present disclosure. In general, the seal member 1 includes a main body 10, a first seal ring 20, and a tapered thin wall 30.

The sealing member 1 is made of an elastic material. According to the concept of the present disclosure, the material of which the sealing member 1 is made should have a certain elasticity or flexibility such that the tapered thin wall 30 of the sealing member 1 can deform or move when subjected to a pressure towards the outside in the radial direction R, thereby expanding the first sealing ring 20 towards the outside in the radial direction R. That is, the first seal ring 20 can be carried by the tapered thin wall 30, so that both the inner diameter and the outer diameter of the first seal ring 20 become large.

It should be understood that any material having elasticity or flexibility that meets the above requirements is included within the scope of the present disclosure. The elastic material according to an embodiment of the present disclosure may include various types of materials having elasticity or flexibility currently known or developed in the future.

For example, in some embodiments, the sealing member 1 may be integrally molded from a silicone rubber material. The elasticity of the silicone rubber material itself may satisfy the above requirements of the embodiments of the present disclosure. In addition, the integral molding process improves the production efficiency of the sealing member 1. The integrally formed sealing member 1 itself is not invaded by moisture and dust, thereby having a better sealing effect.

Further, the sealing member 1 may be made of other rubber-based materials, for example, styrene-butadiene rubber, isoprene rubber, ethylene propylene rubber, butyl rubber, chloroprene rubber, nitrile rubber, and the like. In addition, thermoplastic elastomer materials (e.g., TPE, TPR, TPU, TPO, etc.) may also be used for the material of the sealing member 1.

The body 10 is annular about the axial direction X and has a first side 11 and a second side 12 facing away from each other in the axial direction X. The ring-shaped body 10 encloses an inner space 13 thereof. The body 10 also has a radially inner side wall 14 and a radially outer side wall 15. Although the cross-section of the body 10 is shown as being generally rectangular in fig. 2 and 3, it should be understood that the cross-section of the body 10 may be other geometric shapes. The scope of the present disclosure is not limited in this respect.

The first sealing ring 20 is arranged in the main body 10 about the axial direction X, for example, may be arranged in the inner space 13. The first sealing ring 20 comprises a sealing surface 21 substantially perpendicular to the axial direction X. As shown in fig. 2 and 3, the sealing surface 21 is an annular surface substantially perpendicular to the axial direction X and directed towards the second side 12 of the body 10. The sealing surface 21 is able to come into mutual contact in the axial direction X with a circular end surface of an object entering the inner space 13 of the body 10 from the second side 12, thereby providing a seal. That is, the sealing surface 21 is used to provide an axial seal.

Furthermore, the first sealing ring 20 has a radially inner side wall 22 and a radially outer side wall 23. As shown in fig. 2 and 3, in the non-mounted state, a certain gap is present between the radially outer side wall 23 of the first seal ring 20 and the radially inner side wall 14 of the main body 10, and the two do not contact each other. Due to the presence of this gap, the first sealing ring 20 is able to expand outward in the radial direction R, as will be described in detail below.

The tapered thin wall 30 includes a first section 31. The first section 31 connects the first seal ring 20 to the main body 10 over the entire circumference and is inclined radially R inwardly in the direction from the second side 12 to the first side 11 (the direction from bottom to top in fig. 2 and 3). According to the concept of the present disclosure, the thickness of the tapered thin wall 30 is set such that, when subjected to a pressure toward the outside in the radial direction R, the tapered thin wall 30 can be deformed or moved by the elasticity of the material thereof, thereby expanding the first seal ring 20 toward the outside in the radial direction R.

Referring to fig. 4, the dimensions of tapered thin wall 30 should meet the following requirements. In the illustrative example shown in fig. 4, the seal member 1 is mounted on an object S1. The object S1 together with the sealing member 1 will be connected to the object S2, while the sealing surface 21 of the first sealing ring 20 of the sealing member 1 will be in contact with the outer circumference of the circular end surface S21 of the object S2 to provide an axial seal.

In the state shown in fig. 4, the object S2 has just come into contact with the tapered thin wall 30, and no pressure has been applied to the tapered thin wall 30, causing deformation or movement thereof. This state may be referred to herein as the "non-installed state". In this state, the inner diameter D1 of the tapered thin wall 30 at the second side 12 is larger than the outer diameter DS of the circular end face S21 of the object S2, and the inner diameter D2 of the tapered thin wall 30 at the first side 11 is smaller than the outer diameter DS of the circular end face S21 of the object S2. At this time, the inner diameter of the first seal ring 20 is D3.

If the object S2 moves further into the internal space 13 of the main body 10 based on the state shown in fig. 4, since the inner diameter D2 of the tapered thin wall 30 at the first side 11 is smaller than the outer diameter DS of the circular end surface S21 of the object S2, the object S2 will apply a pressure to the tapered thin wall 30 toward the outside in the radial direction R, so that the tapered thin wall 30 is deformed or moved toward the outside in the radial direction R. In the process, the inner diameter D2 of the tapered thin wall 30 on the first side 11 will gradually become larger, and the tapered thin wall 30 will also drive the first sealing ring 20 to expand toward the outer side in the radial direction R, so that the inner diameter and the outer diameter of the first sealing ring 20 are correspondingly larger.

Referring to fig. 5, after the object S2 is fully seated (i.e., the sealing surface 21 of the first seal ring 20 of the seal member 1 is in sufficient contact with the outer periphery of the circular end face S21 of the object S2 to provide a seal), the inner diameter D2 of the tapered thin wall 30 at the first side 11 is enlarged to be substantially equal to the outer diameter DS of the circular end face S21 of the object S2. Accordingly, the inner diameter of the first seal ring 20 is also enlarged to D4.

In this way, the seal member 1 according to the embodiment of the present disclosure can adaptively adjust the inner diameter D2 of the tapered thin wall 30 on the first side 11 and the radial dimension of the first seal ring 20, thereby being widely adaptable to the outer diameter DS of the different circular end surfaces S21 of the object S2. Therefore, the sealing member 1 according to the embodiment of the present disclosure has wide adaptability, and can secure the reliability of sealing.

In some embodiments, in the uninstalled state, the inner diameter D2 of the tapered thin wall 30 on the first side 11 may be set to a minimum value that substantially fits the outer diameter DS of the circular end face S21 of the object S2. In this way, with the outer diameter DS of the circular end face S21 of the object S2 being the minimum value, the object S2 may enter the interior space 13 of the body 10 from the second side 12 and finally be mounted in position such that the sealing surface 21 of the first seal ring 20 of the seal member 1 and the outer periphery of the circular end face S21 of the object S2 axially contact each other to provide an axial seal. In this process, the object S2 exerts substantially no pressure on the tapered thin wall 30.

With further reference to fig. 6, there is shown the positional relationship between the seal member 1 and the objects S1 and S2 after the object S2 is fully seated in the case where there is a deviation between the rotational axes X1 and X2 of the objects S1 and S2.

In practical use, due to factors such as dimensional deviation of components and/or assembly error, in a state where the objects S1 and S2 are not completely connected in place, the axis of revolution of the object S1 and the seal member 1 mounted thereon is X1, and the axis of revolution of the object S2 is X2. There is a deviation between the axes of revolution X1 and X2. However, in the state shown in fig. 6 where the object S2 is completely mounted in place, the axis of rotation of the seal member 1 is adjusted by the object S2 to coincide with the axis of rotation X2 of the object S2 due to the pressure action of the object S2 on the tapered thin wall 30 of the seal member 1 and the deformability of the seal member 1. In this way, the sealing member 1 achieves "self-centering" with the circular end face S21 of the object S2, thereby ensuring that the sealing surface 21 of the sealing member 1 can always be accurately in contact with the outer peripheral edge of the circular end face S21 of the object S2 to provide reliable sealing.

As can be seen from the above description, in various embodiments of the present disclosure, the tapered thin wall 30 (specifically, the first section 31 of the tapered thin wall 30) connects the main body 10 and the first seal ring 20. In various embodiments, the location where the first segment 31 is connected to the main body 10 and the first seal ring 20 may be located at any location on the main body 10 and the first seal ring 20. The scope of the present disclosure is not limited in this respect.

With continued reference to fig. 1-3, in some embodiments, the first section 31 may be connected to the body 10 via a first connection 32, in particular, the first connection 32 may be connected to the body 10 at a location adjacent to the second side 12. In this way, the first connection 32 is as close as possible to the second side 12 of the body 10, so that the first section 31 has as long an axial dimension as possible. The first section 31 of such a conical thin wall 30 has a greater elastic deformability and can therefore accommodate a larger diameter range.

Furthermore, the first section 31 may also be connected to the first sealing ring 20 via a second connection 33, in particular the second connection 33 may be connected to the radially outer side wall 23 of the first sealing ring 20 at a position adjacent to the sealing surface 21. In this way, the first segment 31 is connected to the radially outer side wall 23 of the first seal ring 20 at a position adjacent to the sealing surface 21, so that after the object S2 is fully seated, the sealing surface 21 of the seal member 1 can be in sufficient and accurate contact with the outer periphery of the circular end face S21 of the object S2 to provide a reliable seal.

With further reference to fig. 2, 3 and 7, a sealing member 1 according to another embodiment of the present disclosure is shown. In such embodiments, the tapered thin wall 30 may also include a second section 34. The second section 34 is arranged to extend away from the body 10 in the axial direction X from the first connection 32 to a tip 35. Tapered wall 30 may also include a second sealing ring 36. A second sealing ring 36 is arranged to project inwardly from the tip 35 in the radial direction R. As shown in FIG. 7, the radially inner end surface 37 of the second seal ring 36 is adapted to contact the sidewall S22 of the object S2 to provide a radial seal.

Referring to fig. 7, the tapered thin wall 30 may include a first section 31 and a second section 34. In such an arrangement, the first section 31 and the second section 34 constitute a "lever" with the first connection 32 as a fulcrum. During the process that the object S2 presses the first section 31 of the tapered thin wall 30 (an arm of a "lever") toward the outside in the radial direction R, so that the first section 31 is deformed or moved in the direction indicated by the arrow a1 in fig. 7, the "lever" pivots about the fulcrum, the first connecting portion 32. As a result, the other arm of the "lever", the second segment 34, will correspondingly move in the direction indicated by arrow a2 in fig. 7 towards the inside in the radial direction R, so that the radially inner end surface 37 of the second sealing ring 36 can be brought into close abutment against the side wall S22 of the object S2. In this manner, a reliable radial seal is provided between the radially inner end surface 37 of the second seal ring 36 and the sidewall S22 of the object S2.

Furthermore, in some embodiments, for example with reference to fig. 2, 3 and 8, the sealing member 1 may further comprise at least one third sealing ring 16. The third seal ring 16 may project radially R outwardly from the radially outer side wall 15 of the body 10. As shown in fig. 8, the third sealing ring 16 may be in contact with the housing 201 of the luminaire controller 2 to provide a seal for the luminaire controller 2.

In one embodiment, as shown in fig. 2, 3 and 8, the sealing member 1 may comprise three third sealing rings 16. These three third sealing rings 16 are arranged in series, parallel to each other, on the radially external side wall 15 of the body 10, in the axial direction X. In other embodiments, the sealing member 1 may include more or fewer third sealing rings 16, e.g., 1, 2, 4, 5, etc. The scope of the present disclosure is not limited in this respect.

With continued reference to fig. 2, 3, and 8, in some embodiments, the body 10 may further include an annular groove 17 recessed from the second side 12 to an interior thereof. By means of the annular groove 17, the sealing member 1 can be reliably mounted to other objects (e.g., the lamp controller 2).

The above sections describe in detail the seal member 1 according to various embodiments of the present disclosure. It is to be understood that the above detailed embodiments of the disclosure are merely illustrative of or explaining the principles of the disclosure and are not limiting of the disclosure. A luminaire controller 2 comprising a sealing member 1 according to an embodiment of the present disclosure will be described below.

Referring to fig. 8, a partial structure of the luminaire controller 2 according to an embodiment of the present disclosure is shown. The luminaire controller 2 comprises a housing 201. The sealing member 1 according to the embodiment of the present disclosure is mounted to the lamp controller 2.

In some embodiments, the light fixture controller 2 may be an outdoor light fixture controller and is adapted to be connected to the controller mounting boss 3 of an outdoor light fixture. As shown in fig. 8, the end of the controller mounting boss 3 is cylindrical. The sealing surface 21 of the sealing member 1 may be in contact with the outer periphery 301 of the circular end face of the cylinder to provide an axial seal. Further, the radially inner end face 37 of the second seal ring 36 of the seal member 1 may be in contact with the cylindrical sidewall 302 to provide a radial seal. Additionally, the sealing member 1 may also provide a seal between the sealing member 1 and the housing 201 of the luminaire controller 2 with its third sealing ring 16. In this way, the sealing member 1 according to embodiments of the present disclosure is able to provide a "triple" seal between the light fixture controller 2 and the controller mounting boss 3 in a simple and reliable manner.

Referring to fig. 9, there is also provided an outdoor luminaire 4 according to an embodiment of the present disclosure. The top of the outdoor lamp 4 is provided with a cylindrical controller mounting boss 3. The controller mounting boss 3 has a circular end face. The circular end face is provided with a mechanical and electrical interface for connecting with the lamp controller 2. Further, the controller mounting boss 3 is also adapted to be connected with the lamp controller 2, and to achieve water and dust resistance via the sealing member 1 according to the embodiment of the present disclosure.

For example, the outdoor luminaire 4 may be a street lamp. Street lamps are subject to erosion by rain, dust, etc. for a long time, and therefore put higher demands on the reliability of their sealing. The sealing member 1 according to embodiments of the present disclosure can be widely adapted to different sizes of the controller mounting boss 3 of the outdoor light fixture 4 and provides a reliable seal, thus having particular advantages.

It is to be understood that the above detailed embodiments of the disclosure are merely illustrative of or explaining the principles of the disclosure and are not limiting of the disclosure. Accordingly, any modification, equivalent replacement, improvement or the like made within the spirit of the present disclosure should be included in the scope of protection of the present disclosure. Also, it is intended that the following claims cover all such changes and modifications that fall within the scope and boundaries of the claims or the equivalents of the scope and boundaries.
