Detailed Description

The lighting device of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the drawings and their related descriptions are only for the purpose of illustrating and describing the present invention, and are not intended to limit the scope of the present invention. For example, elements in the figures may not be drawn to scale. It is further contemplated that elements, conditions, and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

Referring to fig. 1 and 2A-2C, an exemplary lighting device 10 is shown. The lighting device 10 includes a light fixture 110, a mounting rod 120, a bearing 130, and a remotely controllable switch 140. Fig. 1 is a side view of the lighting device 10, fig. 2A and 2B are sectional views of a part of the lighting device 10 in a first state and a second state of the remote controllable switch 140 thereof, respectively, and fig. 2C is a schematic view of the remote controllable switch 140 in a view perpendicular to the plane illustrated in fig. 2A and 2B.

As shown in fig. 1, 2A, and 2B, the lamp 110 has a lamp face 112, a recess 114, and an inner wall 116 located in the recess 114. The lamp face 112 is a light-emitting surface of the lamp 110. The concave portion 114 is a portion where the lamp 110 is connected to the mounting rod 120, and forms a substantially cylindrical receiving space, for example, but not limited thereto. According to some embodiments, the light fixture 110 itself may have a weight distribution that causes the light fixture 110 to eventually stop at a predetermined angle when rotatable relative to the mounting rod 120. That is, the lamp 110 itself has a center of gravity design corresponding to the predetermined angle. Alternatively or additionally, the lighting device 10 may further include a load element (e.g., similar to the load element 360 in fig. 4A) disposed on the lamp 110, the load element being configured to position the lamp 110 at the predetermined angle when facing downward. In fig. 1 and 2A to 2C, the predetermined angle is an angle at which the lamp surface 112 faces downward.

As shown in fig. 1, 2A, and 2B, the mounting rod 120 is partially disposed in the recess 114 of the light fixture 110. The mounting rod 120 may be used to further connect other elements of the light fixture. For example, the lighting device 10 may further include a light pole 150 and at least one fixing element 122, the fixing element 122 being configured to fix the mounting pole 120 to the light pole 150. The fixing element 122 is, for example, but not limited to, a screw.

As shown in fig. 2A and 2B, the bearing 130 is disposed between the lamp 110 and the mounting rod 120. The bearing 130 is configured to allow the light fixture 110 to be rotatably fixed to the mounting rod 120 relative to the mounting rod 120. The bearing 130 is, for example, a ball bearing, but is not limited thereto.

As shown in fig. 2A and 2B, a remotely controllable switch 140 is provided through a portion of the mounting rod 120 located in the recess 114 of the light fixture 110. The remotely controllable switch 140 is configured to abut against the light fixture 110, and in particular against the inner wall 116 of the light fixture 110, when in the first state, such that the light fixture 110 remains stationary relative to the mounting bar 120, as shown in fig. 2A. The remote controllable switch 140 is configured to be disengaged from the light fixture 110 in the second state to allow the light fixture 110 to be rotatable relative to the mounting post 120, as shown in fig. 2B. According to some embodiments, the first state may be an on state of the remotely controllable switch 140 and the second state may be an off state of the remotely controllable switch 140. Of course, the opposite is not excluded. In some embodiments, as shown in fig. 2C, the remote controllable switch 140 may include a body 142 and two retractable portions 144, the two retractable portions 144 being disposed on opposite sides of the body 142. For example, the body 142 may have a shape extending along an axis (vertical axis in fig. 2C) on which two retractable portions 144 are disposed on opposite sides of the body 142. It is understood that the illustration of fig. 2C is for illustrative purposes only and that the remotely controllable switch 140 can have other configurations that are applicable to the present invention. The remote controllable switch 140 is, for example, a solenoid switch, but is not limited thereto.

In the present invention, the remote controllable switch 140 can control the lamp 110 to be in a non-rotatable or rotatable state. Therefore, when the direction of the lamp 110 needs to be adjusted again, the remote-controllable switch 140 can be set to the second state, so that the remote-controllable switch 140 is separated from the lamp 110, and the lamp 110 is in a rotatable state relative to the mounting rod 120. The rotatable lamp 110 will automatically rotate to a predetermined angle under the influence of gravity, in accordance with the design of the center of gravity of the lamp 110 and/or the arrangement of the loading element. Then, the remote-controllable switch 140 can be switched back to the first state, so that the remote-controllable switch 140 is pressed against the inner wall 116 of the lamp 110 again, so that the lamp 110 is kept at the predetermined angle and is not easily influenced by the environment and can be easily turned. Because the remote control can be carried out remotely, the overhead operation is not required to be carried out again.

Referring to fig. 3A-3B, another exemplary illumination device 20 is shown. The lighting device 20 differs from the lighting device 10 in the arrangement direction of the fixing element 222, and other details are not described herein. Fig. 3A is a side view of the illumination device 20, and fig. 3B is a schematic view of the fixing element 222 at a viewing angle perpendicular to the plane illustrated in fig. 3A.

unlike the lighting device 10 in which the at least one securing element 122 is oriented in a downward direction D, the direction D1 in which the at least one securing element 222 of the lighting device 20 is outward from the mounting post 120 subtends a non-zero angle α, which can range from greater than 0 to less than 360, such as about 45, 135, 180, or any other angle, i.e., in cross-section of the mounting post 120 and securing elements (122, 222), the securing element of the lighting device can be oriented in any direction, since the light fixture 110 of the present invention retains the property of being rotatable relative to the mounting post 120 through the bearing 130 and the remote controllable switch 140, the angle between the mounting post 120 and the light post 150 need not be adjusted, as long as the locking is fixed.

Referring to fig. 4A-4B, another exemplary illumination device 30 is shown. The lighting device 30 differs from the lighting device 10 in the arrangement direction of the lamp 110 and further includes a selectively arranged load element 360, and other details are not described herein. Fig. 4A is a side view of the lighting device 30, and fig. 4B is a schematic diagram of the lamp 110 and the load element 360 at a viewing angle perpendicular to the plane shown in fig. 4A.

unlike the lighting device 10 in which the predetermined angle of the lamp surface 112 is oriented in a downward direction (see the downward direction D in fig. 3B), the predetermined angle of the lamp surface 112 of the lighting device 30 is an inclined angle, that is, the lamp surface 112 can have a predetermined angle oriented in any direction as required in the cross-section of the lighting device 110, in the example of fig. 4A-4B, the lighting device 30 further includes a load cell 360 disposed on the lighting device 110, the load cell 360 is configured to position the lighting device 110 at the predetermined angle when facing downward, in which case the direction D2 of the load cell 360 facing outward from the lighting device 110 and the normal vector n facing outward from the lamp surface 112 form a non-zero angle β, the non-zero angle β can range from greater than 0o to less than 360o, such as about 45o, 180o, or any other angle corresponding to the non-zero predetermined angle of the lamp surface 112 of the lighting device 30.

In summary, the lighting device of the present invention does not need to adjust the angle between the lamp and the mounting pole and the lamp post during installation, thereby saving installation time and selecting the most suitable and/or convenient position. When the direction of the lamp surface needs to be adjusted again, manual overhead operation is not needed, time and labor are saved, and the lamp surface can be processed at any time. It is understood that the present invention is not limited to the application of the lighting device to the street lamp in the drawings.

While the invention has been described above with reference to embodiments and examples, it is not intended to be limited thereto.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
