[0003] However, the above-mentioned lamp has the following disadvantages: when the rotating ring 92, the lamp body 93, etc. of the lamp 9 want to change from the oblique lighting state (such as Figure 1 As shown, that is, the angle between the axis of the fixed ring 91 and the axis of the rotating ring 92 is greater than 0°) to restore to the direct illumination state (as shown Figure 3 As shown, that is, when the angle between the axis of the fixed ring 91 and the axis of the rotating ring 92 is 0°), the rotating ring 92, the lamp body 93, etc. will generate a certain torque due to the swing angle, and the greater the swing angle of the rotating ring 92, the lamp body 93, etc., the greater the torque. This makes it more difficult for the rotating ring 92, the lamp body 93, etc. to return to the direct illumination state, reducing the operator or user experience. Summary of the invention

[0008] It can be seen from the above that when the rotating part and the lamp body installed thereon are adjusted to an oblique position relative to the fixed ring, the reset elastic part will be compressed to store energy but will not drive the rotating ring to rotate toward the direct position; and due to the elastic potential energy of the reset elastic part, when the rotating part, the lamp body, etc. are controlled to rotate toward the direct position, the elastic potential energy of the elastic part can balance the torque generated during the swinging process of the rotating part, the lamp body, etc., thereby allowing the rotating part, the lamp body, etc. to rotate smoothly and smoothly toward the direct position, thereby improving the experience of the operator or user.

[0012] As can be seen from the above, the use of a clockwork spring as the reset elastic member can prevent the clockwork spring from hindering the rotation of the rotating member during the compression and energy storage process; at the same time, combined with the structural design of the clockwork spring, the overall structure of the rotation adjustment mechanism can be made more reasonable and facilitate the assembly between the fixed ring, the rotating ring and the reset elastic member.

[0021] A further solution is that the number of the resetting elastic members is two, and the two resetting elastic members are distributed on both sides of the rotating ring along the axial direction of the connecting member; when the rotating ring is in the direct illumination position, the resetting elastic members are in a natural state.
[0022] As can be seen from the above, this design is conducive to balancing the force on the rotating ring, so that the rotating ring can rotate more smoothly relative to the fixed ring.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION
[0036] First embodiment of the lamp
[0037] Reference Figure 4 and Figure 5 The lamp 100 includes a rotation adjustment mechanism 101, a lamp body 102, a light source 103 and an optical element 104. The rotation adjustment mechanism 101 includes a fixed ring 1, a rotating ring 2, a connecting member 3 and a resetting elastic member.
[0038] Combination Figure 6The fixing ring 1 has a receiving position 11 and a first connecting portion 12, and the receiving position 11 penetrates the fixing ring 1 in the height direction of the fixing ring 1. The number of the first connecting portions 12 is preferably two, and the two first connecting portions 12 are distributed on opposite sides of the receiving cavity along the axial direction of the connecting member 3; wherein the axial direction of the connecting member 3 is perpendicular to the height direction of the fixing ring 1.
[0039] Combination Figure 7 The rotating ring 2 is arranged in the accommodating position 11 of the fixed ring 1, and the rotating ring 2 has a second connecting portion 21. The number of the second connecting portions 21 is the same as the number of the first connecting portions 12, and one second connecting portion 21 is matched with one first connecting portion 12; the number of connecting members 3 is the same as the number of the first connecting portions 12, and one connecting member 3 is respectively connected to a corresponding first connecting portion 12 and a second connecting portion 21, so that the rotating ring 2 can rotate relative to the fixed ring 1 around the axis of the connecting member 3; this design enables the rotating ring 2 to rotate smoothly relative to the fixed ring 1.
[0040] Preferably, as in the present embodiment, the first connection part 12 is a countersunk hole, the second connection column is columnar, and the second connection part 21 is provided with a connection hole 211; when the fixed ring 1 and the rotating ring 2 are assembled, the connection member 3 is passed through the countersunk hole and connected to the connection hole 211 on the second connection part 21. For example, the connection member 3 can be a bolt, which is threadedly connected to the connection hole 211 after passing through the countersunk hole; for another example, the connection member 3 can be a pin, which is interference-fitted with the connection hole 211 after passing through the countersunk hole; for another example, the connection member 3 can be a pin shaft, which is inserted into the connection hole 211 after passing through the countersunk hole, and the pin shaft and the connection hole 211 can be bonded and fixed by an adhesive.
[0041] In addition, the rotating ring 2 has a direct illumination position and a plurality of different oblique illumination positions relative to the fixed ring 1. The direct illumination position refers to the axis of the fixed ring 1 and the axis of the rotating ring 2 being coaxially arranged or substantially parallel; the oblique illumination position refers to the axis of the fixed ring 1 and the axis of the rotating ring 2 having a non-zero angle, so that the optically emitted light can be inclined to the outside of the lamp 100 where the axis of the fixed ring 1 illuminates, thereby meeting the different illumination angle requirements of users.
[0042] The reset elastic member is connected between the fixed ring 1 and the rotating ring 2, and the reset elastic member can force the rotating ring 2 to rotate toward the direct-illumination position; wherein, when the rotating ring 2 is in the direct-illumination position, the reset elastic member is preferably in a natural state, that is, the reset elastic member does not apply a driving force to the rotating ring 2 and / or the driving ring. By setting the reset elastic member, when the rotating member and the lamp body 102 mounted thereon are adjusted to an oblique illumination position relative to the fixed ring 1, the reset elastic member will be compressed to store energy but will not drive the rotating ring 2 to rotate toward the direct-illumination position; and due to the elastic potential energy of the reset elastic member, when the rotating member, the lamp body 102, etc. are controlled to rotate toward the direct-illumination position, the elastic potential energy of the elastic member can balance the torque generated during the swinging process of the rotating member, the lamp body 102, etc., thereby enabling the rotating member, the lamp body 102, etc. to rotate smoothly and smoothly toward the direct-illumination position, thereby improving the operator or user experience.
[0043] Preferably, the fixed ring 1 is provided with a first engaging portion in the accommodation position 11, and the first engaging portion is used for engaging and connecting with the first end of the reset elastic member; the rotating ring 2 is provided with a second engaging portion, and the second engaging portion is used for engaging and connecting with the second end of the reset elastic member. This design makes it more convenient to assemble the reset elastic member with the fixed ring 1 and the rotating ring 2.
[0044] Combination Figure 8 In this embodiment, the first engaging portion is the first engaging groove 13, the second engaging portion is the second engaging groove 22, and the reset elastic member is the spring 4. The spring 4 has a first bending portion 41, a second bending portion 42 and a spiral portion 43; the first bending portion 41 is connected to the first end of the spiral portion 43, and the first bending portion 41 is engaged with the first engaging groove 13; the second bending portion 42 is connected to the second end of the spiral portion 43, and the second bending portion 42 is engaged with the second engaging groove 22. By using the spring 4 as the reset elastic member, it is possible to avoid the spring 4 from hindering the rotation of the rotating member during the process of being compressed and storing energy; at the same time, in combination with the structural design of the spring 4, the overall structure of the rotation adjustment mechanism 101 can be made more reasonable, and the assembly between the fixed ring 1, the rotating ring 2 and the reset elastic member is facilitated.
[0045] In order to make the assembly between the fixed ring 1, the rotating ring 2 and the spring 4 more convenient and easy to operate, the first slot 13 is extended along the height direction of the fixed ring 1, and in the height direction of the fixed ring 1, the first slot 13 is located directly above the first connecting portion 12, so that when the rotating ring 2 is rotated into the receiving position 11 of the fixed ring 1, the first bending portion 41 of the spring 4 can be accurately inserted into the first slot 13. In order to optimize the structure of the rotating ring 2 and make the structure of the rotating ring 2 more reasonable, the second slot 22 is formed on the second connecting portion 21, and the second slot 22 extends along the axial direction of the connecting member 3.
[0046] Preferably, a reinforcing rib 411 is provided on the first bent portion 41 of the clockwork spring 4, and when the first bent portion 41 is inserted into the first slot 13, the reinforcing rib 411 abuts against the slot wall of the first slot 13. This design makes the assembly between the reset elastic member and the fixed ring 1 more convenient and easy to operate, and enables a tight mechanism between the first bent portion 41 and the first slot 13, so that the reset elastic member can stably assist the rotating ring 2 to rotate to the straight position.
[0047] In addition, the number of turns of the spiral portion 43 is preferably two-thirds to two turns, so as to ensure that the reset elastic member has sufficient ability to assist the rotating ring 2 to rotate to the direct illumination position, and avoid the reset elastic member hindering the rotating ring 2 from rotating to the oblique illumination positions, and also make the structure of the reset elastic member more simplified and reasonable. Preferably, as in the present embodiment, the number of turns of the spiral portion 43 is approximately one turn. Among them, the reset elastic member can be set to two as required, and the two reset elastic members are distributed on both sides of the rotating ring 2 along the axial direction of the connecting member 3; accordingly, the number of the first clamping parts is also two, and the two first clamping parts are arranged one-to-one with the two reset elastic members and matched, and the number of the second clamping parts is also two, and the two second clamping parts are arranged one-to-one with the two reset elastic members and matched. By setting two reset elastic members, it is beneficial to balance the force on the rotating ring 2, so that the rotating ring 2 can rotate more smoothly relative to the fixed ring 1.
[0048] like Figure 5 As shown, the lamp body 102 is mounted on the rotating member, so that the lamp body 102 can rotate relative to the fixed ring 1 following the rotating member. The light source 103 is mounted in the lamp body 102, so that the lamp body 102 can reliably dissipate heat for the light source 103, so as to ensure the stability and service life of the light source 103. The optical element 104 is preferably mounted in the lamp body 102, and the optical element 104 is located between the rotating member and the light source 103, and the LED lamp beads of the light source 103 are arranged toward the optical element 104, so that the optical element 104 can enhance the lighting effect of the light source 103; of course, as another optional solution, the optical element 104 can also be mounted in or on the rotating ring 2; as another optional solution, the optical element 104 can also be arranged in both the rotating ring 2 and the fixed ring 1.
[0049] From the above, it can be seen that through the design of the rotation adjustment mechanism 101 of the lamp 100, when the rotating ring 2, the lamp body 102, etc. are adjusted to the direct illumination position relative to the fixed ring 1, the rotating parts, the lamp body 102, etc. can be smoothly and smoothly rotated to the direct illumination position, making it easier and more labor-saving for the operator or user to adjust the rotating parts, the lamp body 102, etc., thereby improving the user experience.
[0050] Second embodiment of the lamp

[0052] The reset elastic member is a torsion spring, and the torsion spring is wound around the circumference of the connecting member. Specifically, the torsion spring is sleeved on the second connecting portion of the rotating ring. The first end of the torsion spring is connected to the first clamping portion, and the second end of the torsion spring is connected to the second clamping portion. The torsion spring is used as the reset elastic member, which can also assist the rotating ring to rotate to the straight-illumination position without hindering the rotating ring from rotating to the oblique-illumination positions.
[0053] Lighting system embodiment
[0054] The lighting system includes a control terminal and a lamp, wherein the lamp is the lamp described in the first embodiment or the second embodiment of the lamp. The lamp also includes a power control unit, which is electrically connected to the light source to control the light source to illuminate according to a set mode.
[0055] The control terminal is used to establish an electrical connection with the power control unit of the lamp, and / or the control terminal is used to exchange information with the power control unit of the lamp. Wherein, the control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the power control unit. When the control terminal is an intelligent control panel or a remote control, a first wireless communication module is provided on the power control unit, and a second wireless communication module is provided on the control terminal; the control terminal is electrically connected to the power control unit, and / or the first wireless communication module exchanges information with the second wireless communication module. In addition, the control terminal can also be an intelligent mobile terminal (such as a mobile phone, a tablet computer, an intelligent wearing device, etc.), and can also be an artificial intelligence robot. By setting the above-mentioned lamp, the lighting system enables the rotating part, the lamp body, etc. of the lamp to be adjusted to the direct illumination position relative to the fixed ring, and the rotating part, the lamp body, etc. can be smoothly and smoothly rotated to the direct illumination position, so that the operator or user can adjust the rotating part, the lamp body, etc. more labor-saving and easy to operate, thereby improving the user experience.
