Description

Technical Field

[0001] The present invention relates to the field of lighting, in particular to an LED lamp. Background Art

[0002] LED lights can be installed on the ceiling. In order to meet the needs of different consumers, the illumination angle of LED lights is usually adjustable. However, since these LED lights can adjust the angle, the problem of wire entanglement is easy to occur after the LED light is rotated to adjust the angle. In order to avoid the problem of wire entanglement, in the existing technology, the wires are connected from the top of the LED light to the inside of the LED light, thereby reducing the problem of the wires being entangled on the LED light. However, this still causes the problem of the wires on the LED light being twisted. At the same time, the heat sink of the LED light is usually set at the top of the LED light, and the wires are connected from the top of the LED light to the inside of the LED light, and the heat on the heat sink is easily transferred to the wires. When the wires are exposed to high temperatures for a long time, the insulating glue on their surface is prone to aging. Summary of the Invention

DETAILED DESCRIPTION

[0016] To more clearly illustrate the technical solutions in the embodiments of the present invention, the above briefly describes the drawings required for describing the embodiments. Obviously, the drawings described only represent some embodiments of the present invention, not all embodiments. Those skilled in the art can also derive other design solutions and drawings based on these drawings without inventive effort.

[0017] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0018] Reference Figure 1, an LED lamp includes a light source 1, an inner cylinder 2, an outer cylinder 3, a connecting frame 4, a rotating shaft, a first conductive member and a second conductive member 7, the outer cylinder 3 is used to be installed on the ceiling, the inner cylinder 2 is arranged on the outer cylinder 3, the inner cylinder 2 and the outer cylinder 3 are coaxially arranged, the inner cylinder 2 is arranged on the inner side of the outer cylinder 3, the inner cylinder 2 and the outer cylinder 3 can rotate relative to each other, the light source 1 is fixed on the connecting frame 4, the rotating shaft extends in the left and right directions, the first conductive member is arranged on the outer cylinder 3, the second conductive member 7 is arranged on the inner cylinder 2, the first conductive member and the second conductive member 7 are electrically connected, and the second conductive member 7 is connected to the light source 1 through a wire.

[0019] From the above, it can be seen that when the LED lamp needs to adjust the illumination angle, the connecting frame 4 and the inner cylinder 2 can be relatively swung around the axis of the rotating shaft to adjust the angle of the light emitted by the light source 1. When the angle of the light emitted by the light source 1 needs to be rotated around the vertical axis, the inner cylinder 2 can be rotated to make the inner cylinder 2 and the outer cylinder 3 rotate relative to each other, thereby further adjusting the angle of the light emitted by the light source 1. In addition, by setting the first conductive member 7 and the second conductive member 7, when the inner cylinder 2 and the outer cylinder 3 rotate relative to each other, the first conductive member 7 and the second conductive member 7 remain electrically connected, which can ensure that the power supply of the external device stably transmits electrical energy to the light source 1 through the first conductive member, the second conductive member 7 and the wire. At the same time, the first conductive member and the second conductive member 7 are electrically connected, and the first conductive member and the second conductive member 7 do not need to be connected by wires, which can effectively avoid the entanglement of wires caused by the relative rotation of the inner cylinder 2 and the outer cylinder 3.

[0020] Preferably, the inner cylinder 2 and the outer cylinder 3 are both made of insulating materials, thereby preventing the inner cylinder 2 and the outer cylinder 3 from being electrified.

[0021] In some embodiments, the second conductive member 7 is arranged in an annular shape, and the annular second conductive member 7 is arranged coaxially with the inner cylinder 2. The inner cylinder 2 is provided with a second connection hole that penetrates the side wall of the inner cylinder 2. The second conductive member 7 is arranged on the outer wall of the inner cylinder 2. The second conductive member 7 is provided with a second connection terminal 71. The second connection terminal 71 is inserted into the second connection hole. The second connection terminal 71 is electrically connected to the light source 1 through a wire. This structure is simple and easy to set up. The second conductive member 7 is fixedly connected to the inner cylinder 2. When the inner cylinder 2 and the outer cylinder 3 rotate relative to each other, the second conductive member 7 fixed on the inner cylinder 2 also rotates accordingly. During the relative rotation of the inner cylinder 2 and the outer cylinder 3, the annular second conductive member 7 and the first conductive member are slidably connected, so that the second conductive member 7 and the second conductive member 7 remain connected.

[0022] In some embodiments, the first conductive member includes a first connection terminal 61 and a conductor 62. The outer cylinder 3 is provided with a first connection hole that extends through the sidewall of the outer cylinder 3. The conductor 62 is fixedly connected to the first connection terminal 61 and is made of a conductive material. The conductor 62 abuts against the second conductive member 7, and the second conductive member 7 and the conductor 62 are able to slide relative to each other. This structure is simple and convenient to set up. The conductor 62 is connected to the second conductive member 7 through the first connection hole, ensuring that the two are always connected. The first connection terminal 61 is used to connect to an external power source, so that the power supply of the external device can be used to supply power to the first connection terminal 61.

[0023] In some embodiments, the LED lamp further includes a heat sink 8, which is fixed to the connecting frame 4, and the light source 1 is disposed at the lower end of the heat sink 8. This structure is simple and convenient to set up, and the heat sink 8 can effectively dissipate heat from the light source 1.

[0024] In some embodiments, the connecting frame 4 is annular, with a vertical channel formed inside the annular connecting frame 4. The heat sink 8 covers the upper end of the channel and extends downward into the channel. The light source 1 is disposed in the channel, and the second connecting hole communicates with the channel. This structure is simple and convenient to set up, and can guide heat conduction upward.

[0025] In some embodiments, a wire passage space 9 is provided between the heat sink 8 and the second connection hole. The wires on the second connection terminal 71 pass through the wire passage space 9 and are connected to the light source 1. The wire passage space 9 is provided so that the wires pass through the wire passage space 9, thereby facilitating the connection between the wires and the light source 1.

[0026] In some embodiments, the bottom of the outer cylinder 3 is provided with a base plate 31, which is arranged in an annular shape. The outer cylinder 3 and the inner cylinder 2 are both mounted on the base plate 31. The outer cylinder 3 and the base plate 31 are fixedly connected, while the inner cylinder 2 and the base plate 31 are relatively slidable. This structure is simple and convenient to set up. The provision of the base plate 31 not only increases the contact area with the ceiling top surface, but also facilitates a fixed connection with the ceiling. Furthermore, the top surfaces of the inner cylinder 2 and the base plate 31 are relatively slidable, preventing the inner cylinder 2 and the bottom surface of the ceiling from sliding relative to each other and thus preventing scratches on the ceiling.

[0027] In actual use, in order to make the connection between the bottom plate 31 and the inner cylinder 2 smoother, a thrust bearing is provided between the bottom plate 31 and the lower end surface of the inner cylinder 2.

[0028] In some embodiments, the rotating shaft includes a sleeve 51. The connecting frame 4 has an axial hole. The ends of the sleeve 51 are inserted into the axial hole and the second connecting hole, respectively. The sleeve 51 and the second connecting hole are relatively rotatable. The second connecting terminal is inserted into the sleeve 51. This structure is simple and convenient to set up. With the sleeve 51, the wire connected to the second connecting terminal 71 passes through the sleeve 51 and enters the wire passage space 9, facilitating wire routing.

[0029] The rotating shaft also includes a solid shaft 10. The connecting frame 4 and the inner cylinder 2 are respectively provided with a third connecting hole and a fourth connecting hole adapted to the two ends of the solid shaft 10. The solid shaft 10 is made of insulating material.

[0030] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
