Description

Lamp and lamp mounting component

Technical Field

The present disclosure relates to lighting devices, and more particularly, to a light fixture and a light fixture mounting component.

Background

Lighting devices such as luminaires are indispensable appliances in every home. Most light fixtures, particularly ceiling light fixtures, are typically provided with a globe within the housing of the light fixture in order to protect the light emitters therein and to make the light emitted from the light fixture more soft. Some lamps have a lamp housing surrounded by a housing that does not emit light.

Further, in the conventional lamp, there are generally different mounting parts according to the size of the lamp. When the lamp is assembled to a mounting surface such as a ceiling lamp, the mounting member is first mounted to the ceiling, and then the lamp is fastened to the mounting member by a fastener such as a screw. When a lamp of a different size needs to be replaced, the mounting member needs to be detached from the ceiling, and a new lamp is mounted after the mounting member corresponding to the new lamp is replaced.

SUMMERY OF THE UTILITY MODEL

In the known solution, since the lampshade is installed in the housing by being surrounded by the housing which does not emit light, the part (e.g. the end part) of the housing which is not covered by the lampshade is in a shadow part relative to the light-transmitting lampshade, so that a circle of shadow is formed at the periphery of the light-transmitting lampshade, which affects the overall appearance and user experience of the lamp.

In addition, different lamp corresponds to different installation parts, and the matching between the lamp and the installation parts needs additional fasteners, so that time and labor are wasted during installation or replacement of the lamp, the assembly efficiency is reduced, and the assembly cost is further improved.

Embodiments of the present disclosure provide a light fixture and a light fixture mounting component to at least partially address the above and other potential problems of conventional solutions.

In one aspect of the present disclosure, a light fixture is provided. The luminaire comprises a light-tight housing adapted to receive a luminaire and comprising an opening defined by a wall of the housing; and a light-transmissive lamp cover at least partially surrounded by the wall and disposed in the opening such that the light emitted by the light emitter is output from a light exit surface of the lamp cover, and the light exit surface includes a protrusion protruding from a portion of the light exit surface adjacent to the first end of the wall toward the first end such that the light exit surface at least partially covers the first end.

Embodiments of the present disclosure are capable of achieving a number of beneficial technical effects. For example, by modifying the lamp housing, the end of the housing of the luminaire that is opaque to light is at least partially covered by the lamp housing, so that the entire front face of the luminaire is transparent to light without shadow areas. This improves the appearance effect of lamps and lanterns, has improved user experience.

In some embodiments, the light exit surface smoothly transitions to the first end. In such embodiments, the smooth transition makes the luminaire more aesthetically pleasing and enables the light emitted by the luminaire to be softer and more uniform.

In some embodiments, the lamp enclosure is integrally formed. This arrangement makes the lamp enclosure easier to manufacture and machine and easier to mount to the housing.

In some embodiments, the luminaire further comprises an attachment member arranged on or integrally formed on the housing; and a notch formed on at least one of a second end of the wall opposite the first end and the attachment member for passage therethrough of a cable for transmitting power for the light fixture in a direction perpendicular to the longitudinal axis of the housing. By this arrangement, the housing of the lamp can be flush-mounted on the mounting surface. Such an arrangement allows the fixture to be more aesthetically pleasing while also allowing the fixture to be more securely mounted to a mounting surface.

In some embodiments, the attachment member is arranged or integrally formed on one side of a carrier plate at the inner surface of the wall, the other side of the carrier plate being adapted to carry the light emitter, and the carrier plate comprises a cable through hole for passage therethrough of a cable for transmitting power to the luminaire along the longitudinal axis. Through the arrangement, the lamp can be connected more easily, and the cable is not easy to damage, so that the lamp is safer.

In some embodiments, the attachment part further comprises an annular attachment portion protruding from a surface of the carrier plate facing away from the light emitter, and a plurality of locking blocks protruding from an end of the annular attachment portion towards the wall, and the plurality of locking blocks are evenly arranged circumferentially on the annular attachment portion. Through the arrangement, the lamp can be more conveniently installed on the installation surface, and the installation efficiency is improved.

In some embodiments, the indentations are formed in radial alignment on the second end and the annular attachment portion. Through the arrangement, the cable can pass through the notch more easily and is not damaged easily, and the safety of the lamp is improved.

According to a second aspect of the present disclosure, a luminaire mounting component is provided. The luminaire mounting member is adapted to be arranged on a mounting surface for mounting different sizes of the above described luminaire to the mounting surface, and comprises: an annular mounting portion extending toward the lamp; and a plurality of locking strips formed at an end of the annular mounting portion, and arranged to correspond to the locking blocks of the light fixture for blocking the locking blocks in a direction away from the mounting surface to mount the light fixture on the mounting surface. The lamp mounting component can be suitable for various lamps with different sizes, so that the lamp mounting component does not need to be replaced when the lamp is mounted and replaced. Further, the lamp can be simply mounted on the lamp mounting member. These all improve the assembly efficiency and the user experience of the luminaire.

In some embodiments, the light fixture mounting component further comprises a plurality of mounting notches, the plurality of mounting notches being arranged at an end of the annular mounting portion and the number of mounting notches being equal to the number of locking bars, such that with the locking blocks in a position blocked by the corresponding locking bars, one of the plurality of mounting notches is radially aligned with the notch of the light fixture, such that a cable for transmitting power to the light fixture is held between the notch and the mounting notch. With this arrangement, the cable can be held between the mounting notch and the notch so as not to be easily loosened. This improves the safety of the luminaire.

In some embodiments, an end of at least one of the plurality of locking blocks or an end of at least one of the plurality of locking bars is provided with a stop for preventing over-rotation of the housing. The arrangement enables a user to conveniently install the lamp by only rotating the lamp to a position where the lamp cannot rotate, so that the installation process of the lamp is easier, and the user experience is improved.

As used herein, the term "include" and its various variants are to be understood as open-ended terms, which mean "including, but not limited to. The term "based on" may be understood as "based at least in part on". The term "one embodiment" may be understood as "at least one embodiment". The term "another embodiment" may be understood as "at least one other embodiment".

The structure of the luminaire 100 according to an exemplary embodiment of the present disclosure will be described in detail below with reference to fig. 1 to 8. Wherein fig. 1 shows a cross-sectional view of the luminaire 100 with the first end 1015 of the housing 101 and a portion of the globe 103 shown enlarged; and figure 2 shows a perspective view of the globe 103 of the luminaire 100.

As shown in fig. 1 and 2, in general, the luminaire 100 includes a housing 101 and a lamp housing 103. The housing 101 is made of any suitable material that is opaque to light. The lamp housing 103 is light-transmissive. The light transmission herein may refer to a light transmission manner such as transparency and translucency. Which may be made of any suitable light-transmissive material. The lamp housing 103 has a light exit surface. In some embodiments, only a portion of the light exit surface of the light cover 103 may be light transmissive.

The housing 101 is used to house the light 102. The light 102 may be any suitable component capable of emitting light, such as a Light Emitting Diode (LED), a fluorescent lamp, or an incandescent lamp. As shown in fig. 1, the housing 101 includes an opening defined by a wall 1011 of the housing 101. The opening is used to fit the lamp housing 103. The lamp housing 103 is arranged in the opening at least partly surrounded by the wall 1011 such that light emitted by the luminaire 102 is output from the light exit surface of the lamp housing 103.

Unlike conventional light fixtures, the light exit surface of the lamp housing 103 of the light fixture 100 according to the embodiment of the present disclosure includes the protrusions 1031, as shown in fig. 1 and 2. The protrusion 1031 protrudes from a portion of the light exit surface adjacent to the first end 1015 of the wall 1011 towards the first end 1015, so that the light exit surface can at least partially cover the first end 1015.

By this arrangement, the first end 1015 of the wall 1011 in the shadow portion of the conventional luminaire is enabled to be at least partially covered by the light emitting surface, such that substantially the entire user facing surface of the luminaire 100 is in a light transmitting state without a shadow region. This improves the aesthetics of the luminaire 100 and also improves the user experience.

In some embodiments, the canopy 103 may be conveniently snapped onto the wall 1011 by a plurality of protrusions 1032 located on its circumference. This makes assembly of the luminaire 100 easier. The bosses 1032 may be uniformly arranged in the circumferential direction of the lamp cover 103 in a manner of being integrally formed with the lamp cover 103. A recess may be provided on the wall 1011 at a position corresponding to the projection 1032 so that the projection 1032 is received therein to make the assembly of the lamp cover 103 easier.

As shown in fig. 1 and 3, in some embodiments, the light exit surface of the lamp housing 103 may smoothly transition obliquely to the first end 1015. The smooth transition provides a more aesthetically pleasing light fixture 100 and also provides a softer, more uniform light from light fixture 100. Such a lamp cover 103 can be easily manufactured by integral molding using a mold. This allows the lamp housing 103 to be more easily manufactured and processed and to be more easily mounted to the housing 101.

The luminaire 101 can be mounted on a mounting surface such as a ceiling in a simple and convenient manner. This can be achieved in a number of ways. For example, in some embodiments, as shown in fig. 4, the luminaire further comprises an attachment member 105. The attachment part 1015 may be integrally formed on the housing 101 or be separately formed to be arranged or fitted to the housing 101.

In some embodiments, a carrier plate 1012 may also be included in the light fixture 101, the carrier plate 1012 being used to carry the light emitter 102 on one side thereof, as shown in fig. 5. The attachment part 105 may be arranged on or integrally formed on a side of the carrier plate 1012 facing away from the light emitter 102. Cable vias 1014 can be included on the carrier plate 1012 to facilitate passage of cables for powering the light fixture 100 along the longitudinal axis X of the light fixture 100. Through the arrangement, the lamp can be connected more easily, and the cable is not easy to damage, so that the lamp is safer.

The attachment member 105 may cooperate with the luminaire mounting member 104 disclosed according to the second aspect of the embodiments of the present disclosure to facilitate mounting of the luminaire 100 on a mounting surface. For example, before the light fixture 100 needs to be installed, the light fixture installation member 104 is first installed on the installation surface. The light fixture mounting member 104 may be a standard piece that mates with light fixtures 100 having standard sized attachment members 105, and the light fixtures 100 themselves may be of different sizes and different specifications to mount the light fixtures 100 on a mounting surface.

That is, when it is necessary to replace the lamp 100 of a different size, the lamp mounting member 104 does not need to be removed. The light fixture mounting member 104 can mate with attachment members 105 on different sized light fixtures 100 to mount the light fixture 100 on a mounting surface. This can be achieved by the following exemplary structure.

For example, in some embodiments, as shown in fig. 6 and 7, the luminaire mounting member 104 comprises an annular mounting portion 1041 and a plurality of locking bars 1042. Accordingly, on the attachment member 105, a ring-shaped attachment portion 1051 and a locking block 1052 protruding from the ring-shaped attachment portion 1051, which is provided corresponding to the locking bar 1042, may be provided, as shown in fig. 4. The plurality of locking blocks 1051 and the plurality of locking bars 1042 may be arranged circumferentially uniformly on the annular attachment portion 1051 and the annular mounting portion 1041, respectively.

When the luminaire 100 is installed, the luminaire 100 is moved with the lock blocks 1052 misaligned with the lock bars 1042 such that the lock blocks 1052 are located at positions where the lock bars 1042 are close to the mounting surface. The luminaire 100 is then rotated about the longitudinal axis X of the luminaire 100 such that the locking blocks 1052 are rotated into a position blocked by the locking bars 1042 to mount the luminaire 100 on a mounting surface, as shown in FIG. 8.

With such an arrangement, the light fixture mounting member 104 is enabled to accommodate a variety of light fixtures 100 of different sizes, such that the light fixture 100 does not require replacement of the light fixture mounting member 104 when installed and replaced. Further, the luminaire 100 can be simply mounted on the luminaire mounting part 104 without additional fasteners or the like. These all improve the assembly efficiency and user experience of the luminaire 100.

To prevent over-rotation of the luminaire 100 during installation of the luminaire 100, in some embodiments, stops are provided at the ends of the at least one locking block 1052 and/or the ends of the at least one locking bar 1042, as shown in fig. 4 and 6. By arranging the stopping part, the lamp 100 can be stopped by the stopping part after rotating to the proper position, and the lamp 100 is prevented from being rotated excessively by a user to cause mounting failure. This arrangement allows a user to conveniently mount the lamp 100 by simply rotating the lamp 100 to a position where it cannot be rotated, thereby making the mounting process of the lamp 100 easier and improving the user experience.

Of course, it should be understood that the above-described embodiments for conveniently mounting the light fixture 100 with respect to the lock bar 1042 and the lock block 1052 are merely illustrative and are not intended to limit the scope of the present disclosure. Any other suitable arrangement or configuration is possible. For example, in some alternative embodiments, light fixture 100 may also be conveniently mounted by way of a snap-fit connection, a threaded connection, or the like.

In some embodiments, as shown in fig. 4, a notch 1013 is provided on the second end 1016 and/or the annular attachment 1051 of the wall 1011 opposite the first end 1015 for a cable to pass through. To facilitate cable threading, the second end 1016 and the notch on the annular attachment 1051 are radially aligned. Further, a plurality of mounting notches 1043 may be provided in the annular mounting portion 1041 of the lamp mounting member 104.

After the light fixture 100 is mounted to the light fixture mounting member 104, the mounting notches 1043 and the notches 1013 are aligned. The mounting notch 1043 and the notch 1013 are open in opposite directions and the spacing therebetween is less than or equal to the diameter of the cable to be passed through, so that the cable can be held therebetween in a manner compressed by the gap between the mounting notch 1043 and the notch 1013. That is, "hold" herein means that the cable is compressed in the gap between the mounting notch 1043 and the notch 1013. With this arrangement, the cable can be held firmly between the mounting notch 1043 and the notch 1013 so as not to be loosened easily. This improves the safety of the luminaire.

Further, in some embodiments, there may be more mounting notches 1043 than notches 1013. For example, the number of mounting notches 1043 can be equal to the number of locking bars 1042, such that when the luminaire 100 is in the installed position, there is always one mounting notch 1043 aligned with the notch 1013. The cable can pass between the aligned mounting notch 1043 and notch 1013 and be held securely therebetween. This improves the ease of installation of the luminaire 100.

In the specification and the claims which follow, unless the context requires otherwise, the terms "comprise" and "comprise" are to be construed as embracing the stated elements or groups of elements but not excluding any other elements or groups of elements.

The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that such prior art forms part of the common general knowledge.

It should be understood that the following claims are only provisional claims and are examples of possible claims and are not intended to limit the scope of the claims to any future patent application based on the present application. Elements may be added or deleted in the exemplary claims at a later date to further define or redefine the disclosure.
