Description

Rotation adjusting mechanism, lamp and lighting system Technical Field The invention relates to the technical field of illumination, in particular to a rotation adjusting mechanism, a lamp provided with the rotation adjusting mechanism and an illumination system provided with the lamp. Background With the rising and popular design of no main lamp, lamps such as down lamps, spot lamps, guide rail lamps, line lamps and the like are popular with consumers. The lamp is installed on the rotating ring to rotate along with the rotating ring relative to the fixed ring, the light source is installed in the lamp body, the optical element is installed on the rotating ring and/or the lamp body, the light source faces the optical element, and when the lamp is installed and used, the relative position of the rotating ring and the fixed ring is usually adjusted according to specific illumination requirements, so that the illumination angle achieves the effect required by a user. As shown in fig. 1, the conventional fixed ring 9 is generally provided with an angle scale 91 and a display through groove 92, and the rotating ring is provided with a corresponding pointer at the display through groove 92, so that an installer or a user can determine the adjusted illumination angle according to the scale pointed by the pointer. However, since the relative rotation range between the fixed ring 9 and the rotating ring is usually between 0 ° and 45 ° (when the fixed ring 9 and the rotating ring are at 0 °), the first axis of the fixed ring 9 is usually parallel to the second axis of the rotating ring, and when the fixed ring 9 and the rotating ring are at non-0 °, the first axis and the second axis form a non-zero angle therebetween), the rotation adjustment angle range is not large, and the relative rotation range between the fixed ring 9 and the rotating ring is configured to be 1:1, for example, when the relative rotation range between the fixed ring 9 and the rotating ring is between 0 ° and 20 ° (see fig. 1), the distribution range of the angle scale 91 on the fixed ring 9 is also between 0 ° and 20 ° (see fig. 1), which results in that the display area of the angle scale 91 is limited, so that the installer or the user can not easily and quickly, clearly and accurately read the angle scale 91 pointed by the pointer, the installation and adjustment difficulty of the installer or the user are increased, and the experience of the installer or user is reduced. Disclosure of Invention In order to solve the above problems, a main object of the present invention is to provide a rotation adjustment mechanism that can identify an angle scale more easily. Another object of the present invention is to provide a lamp provided with the rotation adjusting mechanism. It is a further object of the present invention to provide a lighting system provided with a luminaire as described above. In order to achieve the main object of the present invention, the present invention provides a rotation adjustment mechanism, including a fixed ring and a rotating ring, the fixed ring has a receiving position, a first connecting portion, a display through slot and an angle scale, the rotating ring is disposed in the receiving position, the rotating ring has a second connecting portion, the second connecting portion is rotatably connected with the first connecting portion around a first rotation axis, wherein the fixed ring further has a third connecting portion, the angle scale is distributed around the third connecting portion, the display through slot is located between the third connecting portion and the angle scale, the rotating ring has a guiding column, the guiding column extends parallel to the first rotation axis toward the display through slot, the rotation adjustment mechanism further includes a rotating member, the rotating member has a fourth connecting portion, a sliding slot and a pointer, the fourth connecting portion is rotatably connected with the third connecting portion around a second rotation axis, the second rotation axis is parallel to the first rotation axis, the guiding column is slidably disposed in the sliding slot, and the pointer is located at the display through slot. From the above, through the structural design to rotating the piece to and to fixed ring, the cooperation structural design of rotating ring and rotating the piece, make the angle scale on the fixed ring can enlarge angle scale distribution area according to setting up proportion, and then be favorable to increasing angle scale display area, so that this angle scale has the function of enlarged display, thereby be convenient for installer more or user discernment pointer pointed angle scale value more, make the design of rotation adjustment mechanism more humanized, reduce installer or user and adjust degree of difficulty and installation degree of difficulty to the illumination angle of the lamps and lanterns that are equipped with this rotation adjustment mech
