Abstract

The present invention provides a ceiling light fixture adapted to be secured to a light fixture attachment, wherein the ceiling light fixture of the present invention is compact and allows a user to adjust the direction of light emitted therefrom as desired.

Description

Ceiling lamp

Technical Field

The invention relates to a lamp, in particular to a ceiling lamp suitable for being installed on lamp attachments such as a fireproof ceiling and the like, wherein the irradiation direction of light emitted by the ceiling lamp can be adjusted in multiple angles.

Background

Ceiling light fixtures are a common lighting fixture that is adapted to be mounted on a ceiling for indoor lighting. Ceiling lights can be classified into fixed ceiling lights and adjustable ceiling lights according to the adjustability of the direction of illumination of light emitted by the ceiling lights. The illumination angle of fixed smallpox lamps and lanterns is fixed promptly after its installation, can't satisfy the demand that the user adjusted its illumination angle. The ceiling lamp with the adjustable illumination angle can realize multi-angle illumination to the indoor space. When the user adjusts the illumination angle, the user can manually or automatically adjust the illumination angle through preset parameters so as to realize multi-angle illumination.

Fig. 1A of the accompanying drawings shows a conventional ceiling lamp with an adjustable illumination angle, in which a press ring Y presses a rotating body Z1 and is fixed by a screw fixing method. The ceiling lamp shown in fig. 1A requires a large height for the rotation of the rotating body Z1, which results in a limited application of the ceiling lamp and a limited ceiling lamp that cannot be used in a small ceiling space. Secondly, the shape of the rotating body Z1 of the ceiling lamp shown in fig. 1A is larger than 1/2 of a sphere, and the ceiling lamp needs to be manufactured by processes such as a die casting process, so that the ceiling lamp has high process requirements and is easy to have poor rotation. Finally, the ceiling lamp shown in fig. 1A needs a screw X to fix the lamp body, and the production cost is high.

Fig. 1B of the accompanying drawings shows another conventional ceiling lamp with adjustable lighting angle, in which the inner side of the top of the cylinder cover T and the top of the heat sink S of the rotating body Z2 are both provided with arc-shaped concave cavities, and the rolling ball G is disposed between the cylinder cover T and the heat sink S, so that the rotating body Z2 can rotate when a user or an operator applies an external force to the rotating body Z2. The ceiling lamp shown in fig. 1B realizes the rotation of the rotating body Z2 relative to the cylinder cover T through the rolling ball G, which requires the rolling ball G, the cylinder cover T and the arc-shaped concave cavity of the heat sink S to have high precision, and the outer surface of the rolling ball G and the inner surface of the arc-shaped concave cavity are smooth, otherwise, the rotating body Z2 is difficult to rotate relative to the cylinder cover T. Next, the rotation of the rotating body Z2 of the ceiling lamp shown in fig. 1B with respect to the cylinder cover T is substantially realized by the rolling of the rolling ball G, so that the rotation direction of the rotating body Z2 of the ceiling lamp shown in fig. 1B is not easily controlled. Finally, the ceiling lamp shown in fig. 1B realizes the rotation of the rotating body Z2 relative to the cylinder cover T by the rolling ball G. Therefore, when the external force for driving the rotating body Z2 to rotate is removed, the rotating body Z2 may be reset by its own weight, resulting in failure in adjusting the light irradiation direction.

More preferably, the connecting element 40 is configured to keep the rotating cover 30 pressed against the outer side 121 of the support 12 and the light source assembly 20 pressed against the inner side 122 of the support 12.

As shown in fig. 2 to 9C of the drawings, since the rotating cover 30 of the ceiling lamp according to the embodiment of the invention is supported on the outer side 121 of the supporting member 12, and the inner side 122 of the supporting member 12 is disposed toward the light source assembly 20, the inner side of the supporting member 12 forms an inner wall of the operation chamber 100.

As shown in fig. 2 to 9C of the drawings, the concave surface 301 of the rotating cover 30 of the ceiling lamp according to the embodiment of the invention forms a sliding surface 310, wherein the sliding surface 310 is kept pressed against the outer side surface 121 of the supporting member 12, wherein the sliding surface 310 and the outer side surface 121 of the supporting member 12 are both arc-shaped, and the outer side surface 121 of the supporting member 12 protrudes outward, so that the sliding surface 310 of the rotating cover 30 can be attached to the outer side surface 121 of the supporting member 12 and can stably slide and rotate around a point relative to the outer side surface 121 of the supporting member 12. As shown in fig. 2 to 9C of the drawings, preferably, the radius corresponding to the sliding surface 310 of the rotating cover 30 of the ceiling lamp according to the embodiment of the invention is the same as (or the same as) the radius corresponding to the outer side 121 of the supporting member 12, so that the sliding surface 310 of the rotating cover 30 can be always attached to the outer side 121 of the supporting member 12 and the sliding surface 310 of the rotating cover 30 can rotate in a desired direction along the outer side 121 of the supporting member 12 under the action of an external force when sliding relative to the outer side 121 of the supporting member 12, and is not easy to deflect. As shown in fig. 8A and 8C of the drawings, the supporting member 12 is preferably shaped like a truncated-cone so that the sliding surface 310 of the rotating cover 30 slides relative to the outer side surface 121 of the supporting member 12. Accordingly, the light outlet 101 and the operation opening 102 of the operation chamber 100 respectively form two bottom surfaces of the support 12 (or the table formed by the support 12), and the outer side surface 121 of the support 12 forms a spherical surface of the support 12 (or the table formed by the support 12). More preferably, the table formed by the support 12 is formed from a hemisphere.

It should be noted that the sliding surface 310 of the rotating cover 30 and the outer side surface 121 of the supporting member 12 of the ceiling lamp of the present invention are both arc-shaped, and the radius corresponding to the sliding surface 310 of the rotating cover 30 is the same as (or the same as) the radius corresponding to the outer side surface 121 of the supporting member 12, so that when the sliding surface 310 of the rotating cover 30 moves around a point relative to the outer side surface 121 of the supporting member 12, the point around which the sliding surface 310 of the rotating cover 30 moves is a fixed point, and the fixed point is a circle center corresponding to the sliding surface 310 of the rotating cover 30 and the outer side surface 121 of the supporting member 12.

As shown in fig. 2 to 9C of the drawings, the rotating cover 30 of the ceiling lamp according to the embodiment of the invention includes a sliding portion 31 and an extending portion 32 extending from the sliding portion 31, wherein the sliding portion 31 forms the sliding surface 310. Preferably, in order to reduce the friction between the rotating cover 30 and the supporting member 12, the sliding portion 31 is disposed to protrude toward the outer side 121 of the supporting member 12, so as to ensure that the sliding surface 310 can press against the outer side 122 of the supporting member 12 and separate the extending portion 32 of the rotating cover 30 from the outer side 122 of the supporting member 12. In some embodiments, in order to increase the friction between the rotating cover 30 and the supporting member 12, the sliding surface 310 of the rotating cover 30 extends from the sliding portion 31 to the extending portion 32, so that the rotating cover 30 can be in sufficient contact with the supporting member 12.

Preferably, the retaining member 42 is an elastic element, and the retaining member 42 is in a compressed state, so as to apply an upward pushing force on the second end 412 of the connecting member 41 to pull the light source assembly 20 toward the inner side 122 of the supporting member 12, and apply a pushing force on the rotating cover 30 to push the rotating cover 30 toward the outer side 121 of the supporting member 12 and ensure that the rotating cover 30 is pressed against the outer side 121 of the supporting member 12. Preferably, the retainer 42 is a spring. Accordingly, when the rotating cover 30 and the light source assembly 20 rotate synchronously to the desired adjusting position relative to the supporting member 12 and the external force is removed, the rotating cover 30 can be kept pressed against the outer side 121 of the supporting member 12 and maintain the light source assembly 20 at the desired adjusting position under the elastic force of the retaining member 42 (the gravity of the light source assembly 20 may also play a role). Those skilled in the art will appreciate that the force to maintain the rotating cap 30 and the light source assembly 20 in the desired adjustment position is mainly the friction between the rotating cap 30 and the outer side 121 of the support 12. Further, friction between the light source assembly 20 and the inner side 122 of the support 12 may also play a role.

Optionally, the light source assembly 20 is disposed at the first end 411, the retaining member 42 is disposed between the first end 412 and the rotating cover 30 to ensure that the rotating cover 30 is pressed against the outer side 121 of the supporting member 12, wherein the retaining member 42 is an elastic element, and the retaining member 42 is in a stretching state, so as to apply a pulling force upward on the first end 411 of the connecting member 41 to pull the light source assembly 20 toward the inner side 122 of the supporting member 12, and apply a pulling force on the rotating cover 30 to pull the rotating cover 30 toward the outer side 121 of the supporting member 12 and ensure that the rotating cover 30 is pressed against the outer side 121 of the supporting member 12.

As shown in fig. 2 to 9C of the drawings, further, the extending portion 32 of the rotating cover 30 of the ceiling lamp according to the embodiment of the invention is disposed between the first end portion 411 of the connecting member 41 and the holding member 42, so that the sliding portion 31 of the rotating cover 30 can be always attached to the outer side 121 of the supporting member 12 when sliding relative to the outer side 121 of the supporting member 12, and the sliding portion 31 of the rotating cover 30 can rotate along the outer side 121 of the supporting member 12 to a desired direction under the action of an external force and is not easy to deflect. Optionally, the retainer 42 is disposed between the first end 412 and the swivel cap 30, and the extension 32 is disposed on the retainer 42.

As shown in fig. 2 to 9C of the drawings, the outer side 121 and the inner side 122 of the supporting member 12 of the ceiling lamp according to the embodiment of the invention are both arc-shaped, so that the rotating cover 30 rotates around a point relative to the outer side 121 of the supporting member 12 and the light source assembly 20 rotates relative to the inner side 122 of the supporting member 12 synchronously. Further, the connecting element 40 is disposed to keep the rotating cover 30 pressed against the outer side 121 of the supporting member 12 and the light source assembly 20 pressed against the inner side 122 of the supporting member 12, so that when the external force driving the light source assembly 20 to rotate is removed, the friction between the rotating cover 30 and the outer side 121 of the supporting member 12 and/or between the light source assembly 20 and the inner side 122 of the supporting member 12 can keep the rotating cover 30 and the light source assembly 20 tilted synchronously and change the irradiation direction of the light emitted from the ceiling lamp of the present invention.

As shown in fig. 2 to 9C of the drawings, the inner sidewall 202 of the light source assembly 20 of the ceiling lamp according to the embodiment of the invention forms an inner surface 2020, wherein the inner surface 2020 of the light source assembly 20 faces the inner side 122 of the support 12. To facilitate rotation of the light source assembly 20 within the operating chamber 100, the inner surface 2020 is provided with an arcuate shape. Optionally, the inner surface 2020 and the inner side surface 122 of the support 12 are both arc-shaped, and a corresponding radius of the inner surface 2020 is the same as a corresponding radius of the inner side surface 122 of the support 12, so that when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support 12, the inner surface 2020 of the light source assembly 20 can be attached to the inner side surface 122 of the support 12. Further, the inner surface 2020 of the light source assembly 20 can be attached to the inner side surface 122 of the support 12 under the action of the retaining member 42, so that when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support 12, a friction force is generated between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support 12. In other embodiments, to reduce (or avoid) the friction between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support 12, the inner surface 2020 of the light source assembly 20 is away from the inner side surface 122 of the support 12 when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support 12.

As shown in fig. 2 to 9C of the drawings, the ceiling lamp according to the embodiment of the present invention further includes a lubricating mechanism 50, wherein the lubricating mechanism 50 is disposed between the light source assembly 20 and the inner side 122 of the support 12 to separate the light source assembly 20 from the inner side 122 of the support 12, so as to reduce (or avoid) the friction generated between the inner surface 2020 of the light source assembly 20 and the inner side 122 of the support 12 and to facilitate the rotation of the light source assembly 20. Accordingly, the connecting element 40 is configured to keep the rotating cover 30 pressed against the outer side 121 of the supporting member 12 and the light source assembly 20 pressed against the lubricating mechanism 50. At this time, when the external force driving the light source assembly 20 to rotate is removed, the friction between the rotating cover 30 and the outer side 121 of the supporting member 12 keeps the rotating cover 30 and the light source assembly 20 synchronously located at the desired adjustment position and changes the irradiation direction of the light emitted from the ceiling lamp of the present invention.

Preferably, the lubricating pad 50 is made of flexible material such as EVA, silicone, PVC, etc. More preferably, the first contact surface 501 of the lubricating spacer 50 is shaped and sized to fit the inner sidewall 202 of the light source assembly 20, and the second contact surface 502 of the lubricating spacer 50 is shaped and sized to fit the inner side 122 of the support 12, so that the light source assembly 20 can easily rotate relative to the lubricating spacer 50 (and the support 12). Optionally, the lubricating mechanism 50 can also be a smooth coating applied to the inner side 122 of the support 12 and the inner side wall 202 of the light source assembly 20, respectively.

As shown in fig. 2 to 9C of the drawings, the inner sidewall 202 of the light source assembly 20 of the ceiling lamp further forms a wiring groove 2021 and two wire through holes 2022, the connecting member 41 forms a wire channel 410 and two wire dividing holes 4110, wherein the wire dividing hole 4110 is hidden in the wiring groove 2021, and the wire through hole 2022 communicates with the wire dividing hole 4110 through the wiring groove 2021.

As shown in fig. 5A and 5B of the drawings, after the ceiling lamp according to the embodiment of the invention is installed, the light-emitting elements 21 of the light source assembly 20 are generally initially set to face vertically downward, and the light emitted from the ceiling lamp according to the invention is emitted vertically downward. As shown in fig. 6 of the drawings, when a user needs to adjust the irradiation direction of the light emitted from the ceiling lamp of the present invention to deflect to the right, the user can apply an upward force F1 with a proper magnitude on the right side of the light source assembly 20 of the ceiling lamp of the present invention, and under the action of the force F1, the light source assembly 20 rotates upward and leftward, so that the emission direction of the light emitted from the light emitting elements 21 of the light source assembly 20 deflects to the right. While the light source assembly 20 rotates upward and leftward, the light source assembly 20 drives the rotating cover 30 to rotate leftward relative to the supporting member 12 through the connecting element 40. When the user removes the external force F1, the friction between the rotating cover 30 and the supporting member 12 (the friction between the light source assembly 20 and the supporting member 12 may also act) maintains the position of the light source assembly 20 (and the rotating cover 30) relative to the supporting member 12, so that the irradiation direction of the light emitted from the ceiling lamp of the present invention is adjusted to be deflected to the right. Similarly, as shown in fig. 7 of the drawings, when a user needs to adjust the irradiation direction of the light emitted from the ceiling lamp of the present invention to deflect to the left, the user can apply an upward force F2 with a proper magnitude on the left side of the light source assembly 20 of the ceiling lamp of the present invention, and under the action of the force F2, the light source assembly 20 rotates upward and rightward, so that the emission direction of the light emitted from the light emitting elements 21 of the light source assembly 20 deflects to the left. While the light source assembly 20 rotates upward and rightward, the light source assembly 20 drives the rotating cover 30 to rotate rightward relative to the supporting member 12 through the connecting element 40. When the user removes the external force F2, the friction between the rotating cover 30 and the supporting member 12 (the friction between the light source assembly 20 and the supporting member 12 may also play a role) maintains the position of the light source assembly 20 (and the rotating cover 30) relative to the supporting member 12, so that the irradiation direction of the light emitted from the ceiling lamp of the present invention is adjusted to be deflected to the left.

As shown in fig. 2 to 9C of the attached drawings, according to the embodiment of the invention, the ceiling lamp has a compact structure and a small occupied space height, and is convenient to be used in occasions with small or limited space in the interlayer of the ceiling of a house.
