Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a downlight with an adjustable illumination angle. Background Technology

[0002] Downlights are common lighting fixtures suitable for recessed installation in ceilings and other mounting plates, illuminating downwards. Traditionally, downlights have a fixed beam direction; once embedded in a mounting hole in the ceiling, the beam direction is fixed to the opening of the hole, meaning the light shines vertically downwards. However, as people's requirements for lighting applications become more diverse, users increasingly desire to adjust the beam direction to suit their individual needs, such as lighting habits and decorative effects.

[0003] In response to user application needs, a type of lamp with adjustable lighting angle has emerged on the market, as shown in the attached drawings of this utility model specification. Figure 1 As shown, a conventional adjustable lighting fixture 10P is illustrated. The top inner side of the cylindrical cover 11P and the top of the heat sink 13P of the rotating body 12P are both provided with arc-shaped cavities. A rolling ball 14P is disposed between the cylindrical cover 11P and the heat sink 13P, allowing the rotating body 12P to rotate when an external force is applied by a user. The adjustable lighting fixture 10P achieves the rotation of the rotating body 12P relative to the cylindrical cover 11P through the rolling ball 14P. However, this technical solution requires high precision in the design of the arc surfaces of the rolling ball 14P, the cylindrical cover 11P, and the heat sink 13P. Furthermore, the outer surface of the rolling ball 14P and the inner surface of the arc-shaped cavity must remain smooth; otherwise, the rotating body 12P will have difficulty rotating relative to the cylindrical cover 11P. Furthermore, the rotation of the rotating body 12P relative to the cylindrical cover 11P is essentially achieved through the rolling of the ball 13P, making the rotation direction of the rotating body 12P difficult to control and unable to accurately adjust the direction of light illumination. Moreover, the adjustable lighting angle lamp 10P achieves the rotation of the rotating body 12P relative to the cylindrical cover 11P through the ball 14P, meaning that when the external force driving the rotation of the rotating body 12P is removed, the rotating body 12P may reset under its own gravity, resulting in failure to adjust the direction of light illumination.

[0056] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0057] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0058] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0059] Refer to the accompanying drawings in the specification of this utility model. Figures 2 to 12An adjustable downlight 100 according to an embodiment of the present invention is illustrated. The adjustable downlight 100 includes a lamp holder 10 and an illumination component 20. The lamp holder 10 is adapted to be embedded in a corresponding mounting plate, such as a ceiling. The illumination component 20 is adapted to be electrically connected to an external power source to emit light. The illumination component 20 is housed in the lamp holder 10 and can move relative to the lamp holder 10 to adjust the illumination angle, while maintaining the corresponding illumination angle and structural stability.

[0060] Specifically, the lamp holder 10 has a receiving cavity and a light outlet 101 connecting the internal space of the receiving cavity with the external space. The lighting component 20 has a light-emitting surface 202 and a movable ball head 201 facing away from the light-emitting surface 202. The receiving cavity has a ball head movable wall 11 opposite to the light outlet 101. The diameter of the ball head movable wall 11 gradually increases towards the light outlet 101, thus having a structural form that matches the movable ball head 201. The lighting component 20 is housed in the receiving cavity with the movable ball head 201 embedded from the light outlet 101. Based on the relative movement between the movable ball head 201 and the receiving cavity, the lighting component 20 is rotatably disposed in the receiving cavity. Therefore, based on the mutually matching arrangement of the movable ball head 201 and the receiving cavity, the angle of the light-emitting surface 202 of the lighting component 20 can be adjusted while requiring less precision design, making it easy to implement and beneficial for cost control.

[0061] It is worth mentioning that the rotation of the lighting component 20 is limited to ensure the structural stability of the adjustable-angle downlight 100. For details, please refer to [link / reference needed]. Figures 4A to 5 The adjustable downlight 100 includes an inner ring 30 and an outer ring 40, with the light outlet 101 facing downwards. The outer ring 40 is fitted onto the lower end of the lamp holder 10, and the inner ring 30 is mounted on the lower end of the lighting assembly 20. The outer ring 40 has a bottom ring 41 and a mounting wall 42 extending upwards from the bottom ring 41. The mounting wall 42 has two limiting portions 43 arranged along the same diameter. The inner ring 30 is pivotally mounted on the two limiting portions 43, thereby limiting the lighting assembly 20, ensuring structural stability, and flexibly adjusting the lighting direction by rotating the lighting assembly 20.

[0062] It is understood that the inner ring 30 can be pivotally connected to the limiting part 43 by means of rivets, studs or buckles, which is easy to implement and has a simple structure. The specific implementation method does not constitute a limitation of this utility model.

[0063] refer to Figure 9 As shown, the outer ring 40 also includes a pair of elastic slots 44, which are deformed and engaged with the lamp holder 10. Subsequently, the lighting component 20 can be rotated by rotating the outer ring 40, thereby achieving a 360° orientation adjustment effect.

[0064] Furthermore, the adjustable downlight 100 also forms a limiting position on the top of the lighting assembly 20, specifically, referring to... Figure 6A , Figure 6B as well as Figure 8 The adjustable downlight 100 includes a rotating back cover 50 and a connector 60. The lamp holder 10 has a back opening 102 opposite to the light outlet 101. The rotating back cover 50 has a structural form that matches the outer side of the ball head movable wall 11, that is, the rotating back cover 50 has a structural form that matches the side of the ball head movable wall 11 facing away from the receiving cavity. The rotating back cover 50 is supported on the outer side of the ball head movable wall 11. The connector 60 passes through the back opening 102 and connects to the rotating back cover 50 and the movable ball head 201, thereby further limiting the position of the lighting assembly 20.

[0065] On the one hand, based on the fact that the rotating back cover 50 is supported on the outer side of the ball head movable wall 11 and the connecting member 60 connects to the movable ball head 201, the lighting component 20 can be installed in the lamp holder 10 with a downward limit. On the other hand, the movement of the lighting component 20 relative to the lamp holder 10 is limited by the back opening 102 and / or the rotating back cover 50. When the range of movement of the lighting component 20 is too large, the connecting member 60 abuts against the periphery of the back opening 102 and / or the rotating back cover 50 abuts against the lamp holder 10 to limit the movement of the lighting component 20, so as to avoid the excessive range of movement of the lighting component 20 from affecting the light output from the light outlet 101.

[0066] It is worth mentioning that the length design of the connector 60 satisfies the following condition: when the connector 60 passes through the back opening 102 to connect the rotating back cover 50 and the movable ball head 201, the rotating back cover 50 abuts against the outer side of the movable ball head wall 102, and the movable ball head 201 abuts against the inner side of the movable ball head wall 102. This ensures that the movable ball head 201 can move closely against the movable ball head wall 102 and helps to maintain the orientation of the light-emitting surface 202, keeping the adjusted orientation stable.

[0067] Specifically, an elastic pad 61 is provided between the connector 60 and the rotating back cover 50, which helps to prevent the connector 60 from loosening and can adjust the tightness of the connector 60, thereby improving the smoothness of the adjustment of the lighting assembly 20.

[0068] It is understandable that, in practice, the connector 60 is implemented as a connecting element such as a screw or rivet, which helps to reduce the cost of the adjustable downlight 100.

[0069] Preferably, the inner ring 30 is detachably mounted on the lower end of the lighting assembly 20, so that the inner ring 30 and the outer ring 40 can be detachably replaced based on the detachable design of the inner ring 30, thereby improving the user's flexibility and meeting the user's personalized setting needs.

[0070] Specifically, refer to Figure 7 The lower end of the lighting component 20 and the inner ring 30 are equipped with magnetic elements 203 that attract each other, so that the inner ring 30 is magnetically attached to the lower end of the lighting component 20 when the inner ring 30 is close to the lower end of the lighting component 20, so as to facilitate the detachable installation of the inner ring 30 and facilitate the replacement of the inner ring 30 by the user.

[0071] It is understood that the phrase "the lower end of the lighting component 20 and the inner ring 30 are equipped with mutually attractive magnetic elements 203" means that the assembly of the magnetic elements 203 enables the inner ring 30 and the lighting component 20 to be magnetically fixed. It does not limit the lighting component 20 and the inner ring 30 to both be provided with the magnetic elements 203. For example, as illustrated in this embodiment of the present invention, the lower end of the lighting component 20 is provided with a magnet, and the inner ring 30 is made of iron, so that the inner ring 30 can be magnetically fixed to the lower end of the lighting component 20.

[0072] In some embodiments, if the inner ring 30 is made of a non-magnetically adsorbable material, the magnetic element 203 can be assembled in the inner ring 30 so that the inner ring 30 can be magnetically adsorbed to the lower end of the lighting component 20.

[0073] It is worth mentioning that in this embodiment of the present invention, the movable ball head 201 is configured as a heat dissipation element with multiple heat dissipation blades, wherein the upper end of each heat dissipation blade is designed with a corresponding arc shape and forms a shape that matches the movable wall 11 of the ball head, thereby improving the performance of the adjustable downlight with dual functions.

[0074] Specifically, refer to Figure 10AThe movable ball head 201 forms a wire groove 2011 between the two heat dissipation blades by widening the gap between the two adjacent heat dissipation blades, thereby enabling the formation of a corresponding wiring space based on the wire groove 2011 and avoiding the corresponding wires from affecting the relative movement between the movable ball head 201 and the ball head movable wall 11.

[0075] And it is worth mentioning that, for reference Figure 10B The connector 60 is hollow, thereby enabling the formation of a wiring space within the connector 60 to prevent the corresponding wires from affecting the relative movement between the movable ball head 201 and the movable ball head wall 11.

[0076] Therefore, refer to Figure 10C As shown, the cable W leading from the lighting component 20 runs through the wire groove 2011 and is led out from the receiving cavity through the hollow connector 60. The cable W does not obstruct the movable ball head 201 and the movable wall 11 of the ball head, thus ensuring the smooth movement of the lighting component 10.

[0077] It is worth mentioning that, with the aim of improving the aesthetics and dustproof performance of the adjustable-angle downlight 100, reference was made to... Figure 11A The adjustable downlight 100 includes a decorative back cover 70, which is inserted into the top of the lamp holder 10 to improve the dustproof performance of the adjustable downlight 100. The decorative back cover 70 is inserted into the top of the lamp holder 10 to shield the back opening 102 and the rotating back cover 50, thereby preventing dust from falling into the internal space of the accommodating cavity to a certain extent. It also helps to reduce the probability of dust falling between the rotating back cover 50 and the ball head movable wall 11, and between the movable ball head 201 and the ball head movable wall 11, thereby ensuring the smooth operation of the lighting component 20.

[0078] Specifically, refer to Figure 11B As shown, the decorative back cover 70 includes a wiring channel 71 and a wire clamping buckle 72. The wiring channel 71 and the wire clamping buckle 72 have a matching snap-fit ​​structure. For example, in this embodiment of the present invention, the wire clamping buckle 72 is provided with two buckles, and the wiring channel 71 is provided with a corresponding slot. As shown, the cable W led out from the receiving cavity runs through the wiring channel 71. The wire clamping buckle 72 is installed in the wiring channel 71 in a snap-fit ​​manner to form a wire clamping and fixing of the cable W. Thus, wire clamping and fixing can be performed without the use of screws. The operator only needs to press the wire clamping buckle 72 to realize the wire clamping action, which helps to reduce the assembly difficulty of the adjustable lighting angle downlight 100 and improves the installation efficiency.

[0079] It is worth mentioning that the lamp holder 10, the movable ball head 201, the inner ring 30, the outer ring 40, and the rotating back cover 50 can be made of metal or plastic.

[0080] Preferably, in this embodiment of the present invention, the lamp holder 10 and the rotating back cover 50 are made of iron, so as to provide protection in the event of a fire. Figure 12 As shown, the adjustable downlight 100 can form a fireproof cavity through the mounting hole on the ceiling C, which can prevent the fire from spreading rapidly through the mounting hole on the ceiling C to the top of the ceiling C, thus achieving the effect of fire prevention and flame retardancy.

[0081] Further, refer to Figure 12 and Figure 13 As shown, the adjustable downlight 100 according to another embodiment of the present invention is illustrated. In this embodiment, the ball head movable wall 11 integrally protrudes and extends from the upper end of the lamp holder 10 to facilitate the manufacturing and forming of the lamp holder 10, which is beneficial to improving the production efficiency of the adjustable downlight 100.

[0082] In particular, Figure 12 and Figure 13 In the embodiment shown, the outlet for the cable W at the upper end of the movable ball head 201 is also designed to be arc-shaped, so as to combine with the arc-shaped design of the upper end of each heat dissipation blade to form an overall shape that matches the movable wall 11 of the ball head, thereby improving the smoothness of the angle adjustment of the adjustable downlight 100.

[0083] It is worth mentioning that the light-emitting element of the lighting component 20 is preferably an LED light source. It is understood that the light-emitting element can also be an incandescent lamp, fluorescent lamp, etc., and this utility model does not limit it. Preferably, in this embodiment of the utility model, the light-emitting element of the lighting component 20 is a DOB light source, which can be directly connected to the mains high voltage to work without the need for an additional driving power supply, which helps to simplify the structure of the adjustable lighting angle downlight 100.
