Description

Technical Field

[0001] This invention relates to a lighting fixture, and more particularly to a ceiling lighting fixture suitable for installation on fireproof ceilings or other lighting fixture attachments, wherein the direction of light emitted by the ceiling lighting fixture of this invention can be adjusted at multiple angles. Background Technology

[0002] Ceiling lights are common lighting fixtures suitable for installation on ceilings for indoor lighting. Based on the adjustability of the light direction emitted, ceiling lights can be divided into fixed and adjustable types. Fixed ceiling lights have a fixed lighting angle after installation, making it impossible to adjust the angle as needed. Adjustable ceiling lights, on the other hand, provide multi-angle lighting. Users can adjust the lighting angle manually or automatically through preset parameters to achieve multi-angle illumination.

[0003] Attached image Figure 1A The image shows an existing ceiling light fixture with adjustable lighting angle, in which a retaining ring Y presses against the rotating body Z1 and is fixed by screws. Figure 1A The rotating body Z1 of the ceiling light fixture shown requires a considerable height to rotate, which limits its application; it cannot be used in situations with limited ceiling space. Secondly... Figure 1A The rotating main body Z1 of the ceiling light fixture shown is larger than half a sphere, requiring die-casting and other processes for fabrication. This demands high-precision manufacturing and is prone to rotational malfunctions. Finally, Figure 1A The ceiling light fixture shown requires screws to fix the light body, resulting in higher production costs.

[0004] Attached image Figure 1B The image shows another existing ceiling light fixture with adjustable lighting angle. Both the top inner side of the cylindrical cover T and the top of the heat sink S of the rotating body Z2 are provided with arc-shaped cavities. A rolling ball G is disposed between the cylindrical cover T and the heat sink S, so that the rotating body Z2 can rotate when the user or operator applies external force to the rotating body Z2. Figure 1B The ceiling light fixture shown uses a rolling ball G to rotate the main body Z2 relative to the cylindrical cover T. This requires high precision in the rolling ball G, the cylindrical cover T, and the arc-shaped cavity of the radiator S, and the outer surface of the rolling ball G and the inner surface of the arc-shaped cavity must be smooth; otherwise, the rotating body Z2 will have difficulty rotating relative to the cylindrical cover T. Secondly, Figure 1B The rotation of the rotating body Z2 of the ceiling light fixture shown relative to the cylindrical cover T is actually achieved through the rolling of the rolling ball G, resulting in... Figure 1B The rotation direction of the rotating main body Z2 of the ceiling light fixture shown is difficult to control. Finally, Figure 1BThe ceiling light fixture shown uses a rolling ball G to rotate the main body Z2 relative to the cylindrical cover T. Therefore, when the external force driving the rotation of the main body Z2 is removed, the main body Z2 may reset under its own gravity, resulting in the failure to adjust the direction of light illumination.

[0045] As shown in the attached image. Figures 2 to 9C As shown, according to an embodiment of the present invention, the operating chamber 100 of the fixing device 10 of the ceiling light fixture has a light outlet 101 and an operating opening 102 opposite to the light outlet 101. The light source assembly 20 forms an outer side wall 201 and an inner side wall 202 opposite to the outer side wall 201. The inner side wall 202 of the light source assembly 20 is disposed adjacent to the operating opening 102 of the operating chamber 100 and away from the light outlet 101 of the operating chamber 100. Preferably, the inner diameter of the light outlet 101 of the operating chamber 100 is larger than the inner diameter of the operating opening 102. (See attached figures.) Figure 8A and Figure 8CAs shown, preferably, the operating chamber 100 is shaped like a spherical table to facilitate the rotation of the light source assembly 20. Accordingly, the light outlet 101 and the operating opening 102 of the operating chamber 100 respectively form the two bottom surfaces of the operating chamber 100 (or the spherical table formed by the operating chamber 100). More preferably, the spherical table formed by the operating chamber 100 is formed from a hemisphere.

[0046] As shown in the attached image. Figures 2 to 8C As shown, the fixing device 10 of the ceiling light fixture according to an embodiment of the present invention includes a lamp surface 11, a support member 12, and a fixing mechanism 13. The lamp surface 11 has a first side 111 and a second side 112. Both the support member 12 and the fixing mechanism 13 are disposed on the second side 112 of the lamp surface 11. The support member 12 extends obliquely upward and inward from the lamp surface 11. The fixing mechanism 13 is adapted to be fixed to a light fixture attachment to secure the ceiling light fixture of the present invention to the light fixture attachment. The support member 12 forms the operating chamber 100. Accordingly, the lamp surface 11 of the fixing device 10 of the ceiling light fixture according to an embodiment of the present invention is provided to illuminate a space emitting light from the ceiling light fixture of the present invention. Those skilled in the art will understand that the lamp surface 11 of the fixing device 10 of the ceiling light fixture according to an embodiment of the present invention is made of a rigid material. Those skilled in the art will understand that the fixing mechanism 13 can be any mechanism or device capable of fixing or installing the fixing device 10 on a light fixture attachment.

[0047] As shown in the attached image. Figures 2 to 8C As shown, in an embodiment of the present invention, the lamp surface 11 of the fixing device 10 of the ceiling light fixture preferably forms a mounting opening 110, wherein the light outlet 101 of the operating chamber 100 of the support member 12 is directly opposite the mounting opening 110 of the lamp surface 11, so that the light generated by the light source assembly 20 can be emitted from the light outlet 101 of the operating chamber 100 and the mounting opening 110 of the lamp surface 11. Those skilled in the art will understand that the light source assembly 20 can be mounted through the mounting opening 110 of the lamp surface 11.

[0048] As shown in the attached image. Figure 11 As shown, preferably, the support member 12 of the ceiling light fixture according to the embodiment of the present invention further forms a set of heat dissipation channels 120, wherein the heat dissipation channels 120 are all connected to the operating room 100 to dissipate heat from the light source assembly 20.

[0049] As shown in the attached image. Figures 2 to 8CAs shown, exemplarily, the fixing mechanism 13 of the fixing device 10 of the ceiling light fixture according to an embodiment of the present invention includes a bracket 131, an elastic element 132, and a support portion 133, wherein the support portion 133 is disposed on the second side 112 of the lamp surface 11 and extends upward from the lamp surface 11, the elastic element 132 is disposed on the support portion 133, and the bracket 131 is disposed on the elastic element 132, wherein the bracket 131 is configured to stably support the ceiling light fixture of the present invention on the ceiling under the action of the elastic element 132. Those skilled in the art will understand that the figures... Figures 2 to 8C The fixing mechanism 13 of the ceiling light fixture fixing device 10 shown in the embodiment of the present invention is merely illustrative and not a limitation thereof. The fixing mechanism 13 of the ceiling light fixture fixing device 10 of the present invention can be any mechanism or device capable of fixing or installing the fixing device 10 on the light fixture attachment.

[0050] As shown in the attached image. Figures 2 to 9CAs shown, the ceiling light fixture according to an embodiment of the present invention further includes a rotating cover 30 and a connecting element 40. The support member 12 forms an outer side 121 and an inner side 122, wherein the rotating cover 30 is supported on the outer side 121 of the support member 12, and the inner side 122 of the support member 12 is disposed facing the light source assembly 20. The connecting element 40 extends upward from the light source assembly 20 and passes through the operation opening 102 of the operation chamber 100 to connect the rotating cover 30 and the light source assembly 20. The rotating cover 30 is configured to be rotatable about a point relative to the outer side 121 of the support member 12, so that the rotating cover 30 and the light source assembly 20 can rotate about a point synchronously. In other words, since the rotating cover 30 is configured to rotate around a point along the outer surface 121 of the support member 12, and the light source assembly 20 is rotatably disposed in the operating chamber 100 around a point, the connecting element 40 connects the rotating cover 30 and the light source assembly 20 together, and the rotating cover 30 and the light source assembly 20 are separated by the support member 12, the rotating cover 30 and the light source assembly 20 can rotate synchronously around a point relative to the support member 12. Preferably, the rotating cover 30 is umbrella-shaped, wherein the outer diameter of the rotating cover 30 is larger than the inner diameter of the operating opening 102 of the operating chamber 100, and the concave surface 301 of the rotating cover 30 is disposed facing the outer surface 121 of the support member 12 to ensure that the rotating cover 30 is always supported by the support member 12 and that the rotating cover 30 does not slip off the outer surface 121 of the support member 12 when rotating along the outer surface 121 of the support member 12. More preferably, the connecting element 40 is configured to hold the rotating cover 30 against the outer side 121 of the support member 12 and the light source assembly 20 against the inner side 122 of the support member 12.

[0051] As shown in the attached image. Figures 2 to 9C As shown, since the rotating cover 30 of the ceiling light fixture according to the embodiment of the present invention is supported on the outer side 121 of the support member 12, and the inner side 122 of the support member 12 is disposed facing the light source assembly 20, the inner side of the support member 12 forms the inner wall of the operating room 100.

[0052] As shown in the attached image. Figures 2 to 9C As shown, in an embodiment of the present invention, the concave surface 301 of the rotating cover 30 of the ceiling light fixture forms a sliding surface 310, wherein the sliding surface 310 is held against the outer surface 121 of the support member 12, wherein both the sliding surface 310 and the outer surface 121 of the support member 12 are arc-shaped, and the outer surface 121 of the support member 12 protrudes outward, so that the sliding surface 310 of the rotating cover 30 can adhere to the outer surface 121 of the support member 12 and slide stably relative to the outer surface 121 of the support member 12 and rotate around a point. (See attached figures) Figures 2 to 9CAs shown, preferably, the radius corresponding to the sliding surface 310 of the ceiling light fixture's rotating cover 30 according to this embodiment of the invention is the same as (or the same radius) as the radius corresponding to the outer surface 121 of the support member 12. This ensures that when the sliding surface 310 of the rotating cover 30 slides relative to the outer surface 121 of the support member 12, it remains attached to the outer surface 121 of the support member 12. Furthermore, it allows the sliding surface 310 of the rotating cover 30 to rotate in the desired direction along the outer surface 121 of the support member 12 under external force, and prevents deflection. (See attached figures.) Figure 8A and Figure 8C As shown, preferably, the support member 12 is shaped like a frustum, so that the sliding surface 310 of the rotating cover 30 can slide relative to the outer surface 121 of the support member 12. Accordingly, the light outlet 101 and the operation opening 102 of the operating chamber 100 respectively form the two bottom surfaces of the support member 12 (or the frustum formed by the support member 12), and the outer surface 121 of the support member 12 forms the spherical surface of the support member 12 (or the frustum formed by the support member 12). More preferably, the frustum formed by the support member 12 is formed from a hemisphere.

[0053] It is worth noting that the sliding surface 310 of the rotating cover 30 of the ceiling light fixture of the present invention and the outer surface 121 of the support member 12 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 radius) as the radius corresponding to the outer surface 121 of the support member 12. This makes the point around which the sliding surface 310 of the rotating cover 30 moves relative to the outer surface 121 of the support member 12 is a fixed point, which is the center of the circle corresponding to the sliding surface 310 of the rotating cover 30 and the outer surface 121 of the support member 12.

[0054] As shown in the attached image. Figures 2 to 9C As shown, the rotating cover 30 of the ceiling light fixture according to an embodiment of the present invention includes a sliding portion 31 and an extension 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 support member 12, the sliding portion 31 is provided to protrude toward the outer surface 121 of the support member 12, so as to ensure that the sliding surface 310 can abut against the outer surface 122 of the support member 12 and space the extension portion 32 of the rotating cover 30 from the outer surface 122 of the support member 12. In some embodiments, in order to increase the friction between the rotating cover 30 and the support member 12, the sliding surface 310 of the rotating cover 30 extends from the sliding portion 31 to the extension portion 32, so that the rotating cover 30 can fully contact the support member 12.

[0055] As shown in the attached image. Figures 2 to 9CAs shown, the connecting element 40 of the ceiling light fixture according to an embodiment of the present invention includes a connector 41 and a retainer 42, wherein the connector 41 forms a first end 411 and a second end 412, wherein the light source assembly 20 is disposed at the first end 411, and the retainer 42 is disposed between the second end 412 and the rotating cover 30 to ensure that the rotating cover 30 abuts against the outer surface 121 of the support member 12. Preferably, the retainer 42 is an elastic element, and the retainer 42 is in a compressed state, thereby applying an upward thrust to the second end 412 of the connector 41 to pull the light source assembly 20 toward the inner surface 122 of the support member 12, and applying a thrust to the rotating cover 30 to push the rotating cover 30 toward the outer surface 121 of the support member 12 and ensure that the rotating cover 30 abuts against the outer surface 121 of the support member 12. Preferably, the retainer 42 is a spring. Accordingly, when the rotating cover 30 and the light source assembly 20 rotate synchronously relative to the support member 12 to the expected adjustment position and the external force is removed, the rotating cover 30 can be held against the outer surface 121 of the support member 12 and the light source assembly 20 can be maintained in the expected adjustment position under the action of the elastic force of the retaining member 42 (the weight of the light source assembly 20 may also play a role). Those skilled in the art will understand that the force holding the rotating cover 30 and the light source assembly 20 in the expected adjustment position is mainly the frictional force between the rotating cover 30 and the outer surface 121 of the support member 12. Furthermore, the frictional force between the light source assembly 20 and the inner surface 122 of the support member 12 may also play a role.

[0056] Optionally, the light source assembly 20 is disposed at the first end 411, and the retainer 42 is disposed between the first end 412 and the rotating cover 30 to ensure that the rotating cover 30 presses against the outer side 121 of the support member 12. The retainer 42 is an elastic element and is in a stretched state, thereby applying an upward pulling force to the first end 411 of the connector 41 to pull the light source assembly 20 toward the inner side 122 of the support member 12, and applying a pulling force to the rotating cover 30 to pull the rotating cover 30 toward the outer side 121 of the support member 12 and to ensure that the rotating cover 30 presses against the outer side 121 of the support member 12.

[0057] As shown in the attached image. Figures 2 to 9CAs shown, further, according to an embodiment of the present invention, the extension 32 of the rotating cover 30 of the ceiling light fixture is disposed between the first end 411 of the connector 41 and the retainer 42, so that when the sliding portion 31 of the rotating cover 30 slides relative to the outer surface 121 of the support member 12, it can always adhere to the outer surface 121 of the support member 12, and the sliding portion 31 of the rotating cover 30 can rotate in the expected direction along the outer surface 121 of the support member 12 under the action of external force and is not prone to deflection. Optionally, the retainer 42 is disposed between the first end 412 and the rotating cover 30, and the extension 32 is disposed in the retainer 42.

[0058] As shown in the attached image. Figures 2 to 9C As shown, in this embodiment of the ceiling light fixture, the outer surface 121 and the inner surface 122 of the support member 12 are both arc-shaped, so that the rotating cover 30 relative to the outer surface 121 of the support member 12 and the light source assembly 20 relative to the inner surface 122 of the support member 12 can rotate synchronously around a point. Further, the connecting element 40 is configured to keep the rotating cover 30 pressing against the outer surface 121 of the support member 12 and the light source assembly 20 pressing against the inner surface 122 of the support member 12, so that when the external force driving the rotation of the light source assembly 20 is removed, the friction between the rotating cover 30 and the outer surface 121 of the support member 12, and / or between the light source assembly 20 and the inner surface 122 of the support member 12, can maintain the synchronous tilting of the rotating cover 30 and the light source assembly 20 and the change in the illumination direction of the light emitted by the ceiling light fixture of this invention.

[0059] As shown in the attached image. Figures 2 to 9CAs shown, in an embodiment of the present invention, the inner wall 202 of the light source assembly 20 of the ceiling light fixture forms an inner surface 2020, wherein the inner surface 2020 of the light source assembly 20 faces the inner surface 122 of the support member 12. To facilitate rotation of the light source assembly 20 within the operating chamber 100, the inner surface 2020 is arc-shaped. Optionally, both the inner surface 2020 and the inner surface 122 of the support member 12 are arc-shaped, and the radius corresponding to the inner surface 2020 is the same as the radius corresponding to the inner surface 122 of the support member 12, thereby enabling the inner surface 2020 of the light source assembly 20 to adhere to the inner surface 122 of the support member 12 when the light source assembly 20 is driven to rotate relative to the inner surface 122 of the support member 12. Furthermore, under the action of the retainer 42, the inner surface 2020 of the light source assembly 20 can adhere to the inner side surface 122 of the support member 12, thereby generating friction between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support member 12 when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support member 12. In other embodiments, in order to reduce (or avoid) the friction generated between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support member 12, the inner surface 2020 of the light source assembly 20 is moved away from the inner side surface 122 of the support member 12 when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support member 12.

[0060] As shown in the attached image. Figures 2 to 9C As shown, the ceiling light fixture according to an embodiment of the present invention further includes a lubrication mechanism 50, wherein the lubrication mechanism 50 is disposed between the light source assembly 20 and the inner surface 122 of the support member 12 to separate the light source assembly 20 and the inner surface 122 of the support member 12, thereby reducing (or avoiding) the frictional force generated between the inner surface 2020 of the light source assembly 20 and the inner surface 122 of the support member 12 and making the light source assembly 20 easier to rotate. Accordingly, the connecting element 40 is configured to keep the rotating cover 30 pressed against the outer surface 121 of the support member 12 and the light source assembly 20 pressed against the lubrication mechanism 50. At this time, when the external force driving the rotation of the light source assembly 20 is removed, the frictional force between the rotating cover 30 and the outer surface 121 of the support member 12 maintains the synchronous position of the rotating cover 30 and the light source assembly 20 in the expected adjustment position and the change of the illumination direction of the light emitted by the ceiling light fixture of the present invention.

[0061] As shown in the attached image. Figures 2 to 9CAs shown, exemplarily, the lubrication mechanism 50 of the ceiling light fixture according to an embodiment of the present invention is the lubrication pad, wherein the lubrication pad 50 forms a first contact surface 501 facing the light source assembly 20 and a second contact surface 502 facing the inner side surface 122 of the support member 12, wherein the surface of the first contact surface 501 is smooth to facilitate rotation of the light source assembly 20 relative to the lubrication pad 50 (and the support member 12). Preferably, the lubrication pad 50 is made of a flexible material such as EVA, silicone, or PVC. More preferably, the shape and size of the first contact surface 501 of the lubrication pad 50 are adapted to the inner sidewall 202 of the light source assembly 20, and the shape and size of the second contact surface 502 of the lubrication pad 50 are adapted to the inner side surface 122 of the support member 12, so as to facilitate rotation of the light source assembly 20 relative to the lubrication pad 50 (and the support member 12). Optionally, the lubrication mechanism 50 may also be a smooth coating applied to the inner side surface 122 of the support member 12 and the inner side wall 202 of the light source assembly 20, respectively.
