Description

Technical Field

[0001] This disclosure pertains to the field of lighting, specifically relating to a luminaire and a downlight. Background Technology

[0002] A light diffuser is an optical element used to scatter light. By incorporating a light diffuser into a luminaire, light can be evenly distributed in all directions, providing uniform and soft illumination. It is known that different lighting effects and luminaire appearances can be achieved by changing the position of the light diffuser. However, in some existing luminaires, the position of the light diffuser is not easily adjustable, for example, requiring the luminaire housing to be disassembled, resulting in a poor user experience. Therefore, it is desirable to provide a luminaire with an easily adjustable light diffuser. Utility Model Content

[0073] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0074] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0075] The following is for reference. Figures 1 to 4 A first embodiment according to this disclosure is described.

[0076] refer to Figures 1 to 4 A first embodiment of this disclosure provides a lamp fixture including a housing 100, a light source 400, and a light-transmitting system. The housing 100 includes an opening 110. The light source 400 is disposed inside the housing 100, and light emitted by the light source 400 can pass through the opening 110. The light-transmitting system is configured to be removably mounted inside the housing 100 via the opening 110 to scatter light passing through the opening 110. The light-transmitting system includes a tubular support 200 and a light-transmitting cover 300, the light-transmitting cover 300 being connected to an axial end of the tubular support 200. The light-transmitting system is configured to be selectively mounted to the housing 100 in a first orientation or a second orientation opposite to the first orientation. When the light-transmitting cover 300 is mounted to the housing 100 in a first orientation, it is at a first vertical distance D1 from the light source 400, thereby producing a surface-mount visual effect. When the light-transmitting cover 300 is mounted to the housing 100 in a second orientation, it is at a second vertical distance D2 from the light source 400, which is less than the first vertical distance D1, thereby producing an embedded-mount visual effect.

[0077] As an example, the luminaire according to the first embodiment of this disclosure can be a downlight. Of course, the luminaire is not limited to a downlight; for example, in other embodiments, the luminaire can also be a spotlight, etc.

[0078] As an example, the tubular support 200 may include a first axial end 210 and a second axial end 220 opposite to each other, and the light-transmitting cover 300 may be connected to the first axial end 210.

[0079] As an example, the light source 400 can be an LED light source, such as the light source 400 may include multiple LED beads.

[0080] As an example, the opening 110 can have a shape that conforms to the contours of the light-transmitting system. For instance, the opening 110 can be circular and have a diameter that is approximately the same as the outer diameter of the tubular support 200.

[0081] As an example, the light-transmitting system can be configured to be removably mounted inside the housing 100 via the opening 110 to be fixed relative to the housing 100.

[0082] In this disclosure, by providing a light-transmitting system that can be installed in a first orientation and a second orientation opposite to the first orientation, the installation position of the light-transmitting cover 300 can be changed according to the orientation of the light-transmitting system, making the installation position of the light-transmitting cover 300 easy to adjust, thereby making the lamp easy to use.

[0083] refer to Figures 2 to 4 The inner circumferential surface of the tubular support 200 is provided with a texture that has a light-scattering effect.

[0084] As an example, the inner periphery of the tubular support 200 may have an undulating shape. For instance, the inner periphery of the tubular support 200 may be provided with a plurality of annular grooves extending in the circumferential direction of the tubular support 200.

[0085] In other examples, the inner circumferential surface of the tubular support may also be provided with a stepped structure.

[0086] In this disclosure, by setting a texture that has the effect of scattering light, the anti-glare effect of the light transmission system can be enhanced, thereby improving the lighting effect of the lamp.

[0087] It should be understood that a texture that scatters light is not necessary. In other embodiments, the inner peripheral surface of the tubular support 200 may be smooth.

[0088] refer to Figure 3 The inner circumferential surface of the tubular support 200 is provided with a slot 230, which receives the edge of the light-transmitting cover 300.

[0089] As an example, the slot 230 may extend in the circumferential direction of the tubular support 200. For instance, the slot 230 may extend circumferentially around the tubular support 200, and the entire edge of the light-transmitting cover 300 may be received in the slot 230.

[0090] In this disclosure, by providing the slot 230, the light-transmitting cover 300 can be installed onto the tubular bracket 200 without the aid of other parts, allowing the luminaire to have fewer parts, thereby facilitating miniaturization and weight reduction. Furthermore, by providing the slot 230, the tubular bracket 200 can be separated from the light-transmitting cover 300, allowing the luminaire to achieve different lighting effects by replacing different types of light-transmitting covers 300.

[0091] refer to Figure 3 The luminaire also includes a connecting element 500. The connecting element 500 is configured to penetrate the wall of the housing 100 to connect the light transmission system to the housing 100, thereby mounting the light transmission system to the housing 100.

[0092] As an example, the housing 100 may include a flat plate portion 170 with an opening 110 and an annular wall portion 180 intersecting and connected to the flat plate portion 170. A mounting hole 121 penetrating the annular wall portion 180 may be formed on the annular wall portion 180. The connecting element 500 may be configured to be detachably inserted into the mounting hole 121 from the outside of the housing 100 to engage with the light-transmitting system.

[0093] As an example, the luminaire may include multiple connecting elements 500. For instance, the multiple connecting elements 500 may be evenly spaced in the circumferential direction of the light-transmitting system.

[0094] In this disclosure, by providing the connecting element 500, even when the light-transmitting system cannot be accessed from outside the luminaire, the light-transmitting system can be separated from the housing 100 by operating the connecting element 500, making the luminaire easy to use.

[0095] refer to Figure 3 The connecting element 500 is configured to engage with the housing 100.

[0096] As an example, the connecting element 500 can be a threaded fastener, such as a screw.

[0097] In this disclosure, by screwing the connecting element 500 into the housing 100, the light transmission system and the housing 100 can be arranged compactly, thereby facilitating the miniaturization of the luminaire.

[0098] refer to Figure 3 The light-transmitting system is provided with a mounting groove 240, which is configured to receive the end of the connecting element 500.

[0099] As an example, the mounting slot 240 can be provided on the outer peripheral surface of the tubular support 200.

[0100] As an example, the light-transmitting system may include a plurality of mounting slots 240. For instance, the plurality of mounting slots 240 may include a first mounting slot 241 and a second mounting slot 242. The first mounting slot 241 may be disposed at a second axial end 220, and the second mounting slot 242 may be disposed at a first axial end 210. Accordingly, the coupling element 500 may be configured to removably engage with the first mounting slot 241 when the light-transmitting system is mounted to the housing 100 in a first orientation, and to removably engage with the second mounting slot 242 when the light-transmitting system is mounted to the housing 100 in a second orientation.

[0101] In other instances, the light-transmitting system may also have only one mounting slot, which may be positioned approximately in the middle of the tubular support in the axial direction of the tubular support.

[0102] In this disclosure, by providing the mounting slot 240, the light transmission system and the housing 100 can be arranged compactly, which is conducive to the miniaturization of the lamp.

[0103] refer to Figure 3 The mounting groove 240 extends in the circumferential direction of the tubular support 200.

[0104] As an example, the mounting groove 240 can extend circumferentially around the tubular support 200. In other words, the mounting groove 240 can have an annular shape.

[0105] In this disclosure, by extending the mounting groove 240 in the circumferential direction, the mounting groove 240 can occupy a large angular range in the circumferential direction, making it easy to align the mounting groove 240 and the connecting element 500 with each other, thereby making the luminaire easy to use.

[0106] refer to Figure 3 The mounting groove 240 is configured to mate with the end shape of the connecting element 500, and the end of the connecting element 500 is configured to taper toward the mounting groove 240.

[0107] As an example, the end of the connecting element 500 may have a tapered shape. Accordingly, the mounting groove 240 may have a generally V-shaped cross-section.

[0108] In this disclosure, by fitting the end shapes of the mounting groove 240 and the connecting element 500 together, and by tapering the end of the connecting element 500, the end of the connecting element 500 can easily enter the mounting groove 240, making the luminaire easy to use.

[0109] refer to Figure 2 and Figure 4 The light-transmitting cover 300 is configured to be flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a first orientation, and to be displaced relative to the opening 110 toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a second orientation.

[0110] As an example, the first axial end portion 210 may be flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a first orientation, and displaced toward the interior of the housing 100 relative to the opening 110 when the light-transmitting system is mounted to the housing 100 in a second orientation. Conversely, the second axial end portion 220 may be flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a second orientation, and displaced toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a first orientation.

[0111] In this disclosure, by making the light-transmitting cover 300 flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a first orientation, a surface-mount visual effect can be produced. Furthermore, by shifting the light-transmitting cover 300 relative to the opening 110 toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a second orientation, an embedded-mount visual effect can be produced.

[0112] The following is for reference. Figures 5 to 9 The second embodiment according to this disclosure is described. The second embodiment is a variation of the first embodiment. For features that are the same as or similar to those in the first embodiment, the same reference numerals are used in this embodiment, and detailed descriptions of these features are omitted.

[0113] refer to Figures 5 to 8 A second embodiment of this disclosure provides a lamp that includes a housing 100, a light source 400, and a light-transmitting system. The light-transmitting system is configured to be removably mounted inside the housing 100 via an opening 110 and to scatter light through the opening 110, and the light-transmitting system is configured to be rotatable to a plurality of angular positions about a lateral rotation axis AX1 parallel to the opening 110.

[0114] As an example, when the light fixtures are installed in the ceiling, the horizontal rotation axis AX1 can be a horizontal axis.

[0115] refer to Figure 8 The light transmission system is configured to snap into the housing 100 for installation.

[0116] As an example, the light-transmitting system may be provided with a mounting groove 240, and the housing 100 may be provided with a mounting protrusion 122. The mounting groove 240 is configured to receive the mounting protrusion 122 to mount the light-transmitting system to the housing 100, and to be separable from the mounting protrusion 122 to allow the light-transmitting system to be removed from the housing 100. For example, the mounting groove 240 may have the same configuration as the mounting groove in the first embodiment. The mounting protrusion 122 may be integral with at least a portion of the housing 100 and protrude inwardly from the wall of the housing 100. In other embodiments, the light-transmitting system may be provided with a mounting protrusion, while the housing may be provided with a mounting groove.

[0117] As an example, the mounting groove 240 is configured to mate with the shape of the mounting protrusion 122, which is configured to taper toward the mounting groove 240.

[0118] As an example, the mounting protrusion 122 can extend in the circumferential direction of the tubular support 200, for example, the mounting protrusion 122 can extend around the entire circumference.

[0119] In this disclosure, by snapping the light-transmitting system into the housing 100, the light-transmitting system can be installed into the housing 100 without the aid of other connecting elements (e.g., the connecting element 500 described above), thus simplifying the installation and removal process of the light-transmitting system by eliminating the need for the user to operate the connecting elements. Furthermore, without the need for connecting elements, the luminaire can have fewer parts, which is beneficial for miniaturization and weight reduction.

[0120] refer to Figure 9 The multiple angular positions include an operable angular position AG1. The light transmission system is configured to be at least partially exposed to the outside of the housing 100 via the opening 110 when in the operable angular position AG1.

[0121] As an example, the light-transmitting system can be rotated to several different operable angular positions AG1.

[0122] As an example, the light transmission system can be configured such that, when in the operable angle position AG1, the tubular support 200 is at least partially exposed to the outside of the housing 100 via the opening 110, for example, such that a portion of the outer peripheral surface of the tubular support 200 is exposed to the outside of the housing 100.

[0123] In this disclosure, by setting an operable angle position AG1, the light-transmitting system can be easily accessed from the outside of the lamp when rotated to the operable angle position AG1, making the light-transmitting system easy to separate from the housing 100.

[0124] refer to Figure 6 and Figure 7 The multiple angular positions include a neutral angular position AG2. The light-transmitting cover 300 is configured to be flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a first orientation and is in the neutral angular position AG2, and to be displaced relative to the opening 110 toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a second orientation and is in the neutral angular position AG2.

[0125] As an example, the first axial end portion 210 can be flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a first orientation and at a neutral angle position AG2, and displaced relative to the opening 110 toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a second orientation and at a neutral angle position AG2. Conversely, the second axial end portion 220 can be flush with the opening 110 when the light-transmitting system is mounted to the housing 100 in a second orientation and at a neutral angle position AG2, and displaced toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a first orientation and at a neutral angle position AG2.

[0126] In this disclosure, by aligning the light-transmitting cover 300 with the opening 110 when the light-transmitting system is mounted to the housing 100 in a first orientation and is at a neutral angle position AG2, a surface-mount visual effect can be achieved. Furthermore, by shifting the light-transmitting cover 300 relative to the opening 110 toward the interior of the housing 100 when the light-transmitting system is mounted to the housing 100 in a second orientation, an embedded-mount visual effect can be achieved.

[0127] refer to Figures 5 to 7 The light-transmitting system is configured to rotate around a longitudinal rotation axis AX2 that is perpendicular to the transverse rotation axis AX1.

[0128] As an example, when the light fixtures are installed in the ceiling, the longitudinal rotation axis AX2 can be a vertical axis.

[0129] As an example, the longitudinal rotation axis AX2 can intersect with the transverse rotation axis AX1.

[0130] In this disclosure, by setting a longitudinal rotation axis AX2, the light transmission system can have a large rotation range, enabling the luminaire to have more lighting directions and more operable angular positions AG1.

[0131] refer to Figure 6 and Figure 7 The housing 100 includes an outer shell 130, an intermediate shell 140, and an inner shell 150. The outer shell 130 has an opening 110. The intermediate shell 140 is located radially inside the outer shell 130 and is rotatable relative to the outer shell 130 about a longitudinal rotation axis AX2. The inner shell 150 is located radially inside the intermediate shell 140 and is rotatable relative to the intermediate shell 140 about a transverse rotation axis AX1. A light-transmitting system is configured to engage with the inner shell 150.

[0132] As an example, the outer casing 130 may include a flat plate portion 170 with an opening 110 and an annular wall portion 180 intersecting and connected to the flat plate portion 170. For example, an intermediate casing 140 may be disposed radially inside the annular wall portion 180, and a transverse rotation axis AX1 may pass through the annular wall portion 180.

[0133] As an example, the inner housing 150 may be provided with a mounting protrusion 122. For example, the mounting protrusion 122 may be integral with the inner housing 150 and protrude inward from the inner surface of the inner housing 150.

[0134] As an example, the light source 400 can be located in the inner housing 150.

[0135] In this disclosure, by engaging the light-transmitting system with the inner housing 150, the light-transmitting system and the housing 100 can be arranged compactly, thereby facilitating the miniaturization of the luminaire.

[0136] The above are merely preferred embodiments of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this disclosure, and these improvements and modifications should also be considered within the scope of protection of this disclosure.
