DETAILED DESCRIPTION

[0029] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The utility model relates to a downlight lifting structure, which comprises a lamp body 100, a movable frame 300 and a light guide seat 400.

[0031] like Figure 1 、 Figure 2 and Figure 3As shown, the outer contour of the lamp body 100 is cylindrical, and a light source assembly 200 is installed on the lamp body 100. The light source assembly 200 includes electrical components such as lamp beads and circuit boards. When the light source assembly 200 is powered on, light is generated, and the light is projected to the outside of the lamp body 100 for illumination. The shape of the movable frame 300 is not limited. In this embodiment, the movable frame 300 includes two parallel rods 310 and a connecting ring 320 connected between the two rods 310. The movable frame 300 is plugged into the lamp body 100 through the rods 310 on both sides, and the movable frame 300 can move relative to the lamp body 100, and the movable frame 300 can be positioned at the current position relative to the lamp body 100. The direction of movement of the movable frame 300 relative to the lamp body 100 is the irradiation direction along the light source assembly 200 to the outside of the lamp body 100. As shown Figure 1 and Figure 3 As shown, in the illustrated orientation, the illumination direction of the lamp source assembly 200 is vertically downward, and the movable frame 300 moves in an up-and-down direction relative to the lamp body 100. A light projection port 410 is defined on the light guide base 400. The light guide base 400 and the movable frame 300 can be rotatably connected via a damping shaft. The light guide base 400 and the movable frame 300 can rotate relative to each other and can be positioned relative to each other. Light generated by the lamp source assembly 200 can be projected outward through the light projection port 410.

[0032] In actual use, such as Figure 1 As shown, the light guide base 400 can be used as a support, the light guide base 400 is fixed on the ceiling, and the lamp body 100 is located above the light guide base 400. The light source component 200 irradiates vertically downward through the light projection port 410. When the irradiation direction of the light source component 200 needs to be changed, as shown in FIG. Figure 4 As shown, by moving the lamp body 100, the lamp body 100 and the movable frame 300 rotate relative to the light guide base 400, thereby changing the illumination direction of the light source assembly 200. At the same time, the lamp body 100 and the movable frame 300 can be moved relative to each other according to the illumination angle of the light source assembly 200, and the vertical distance between the lamp body 100 and the light guide base 400 can be adjusted. This allows the light source assembly 200 to illuminate outward through the light projection port 410 to the maximum extent possible, reducing the light blocking of the light source assembly 200 by the light guide base 400. The user can adjust the relative distance and angle between the lamp body 100 and the light guide base 400. Different positions can ensure that light passes through the light projection port 410 to form different illumination ranges and brightness to meet different usage requirements.

[0033] In some embodiments of the present invention, Figure 2 、 Figure 3 and Figure 5As shown, the lamp body 100 is provided with a first elastic member 500. The first elastic member 500 can be a spring, or a spring-coupled ball bearing or other structural member. The movable frame 300 is provided with a plurality of retaining recesses 301, each of which is sequentially distributed along the direction of movement of the movable frame 300 relative to the lamp body 100. In this embodiment, a plurality of retaining recesses 301 are provided on the rods 310 on both sides of the movable frame 300, and each retaining recess 301 on the same rod 310 is formed into a generally wavy shape. A first elastic member 500 is mounted on each side of the lamp body 100, with one first elastic member 500 aligned with each rod 310. The first elastic member 500 is configured so that when the movable frame 300 moves relative to the lamp body 100, the first elastic member 500 elastically slides in and out of each retaining recess 301 in sequence. When the movable frame 300 is stationary relative to the lamp body 100, the first elastic member 500 engages with the retaining recess 301 currently aligned with it, thereby restricting the movement of the movable frame 300. When adjusting the position, the user pulls the lamp body 100 , the movable frame 300 moves relative to the lamp body 100 , and the first elastic member 500 slides out of the current recess 301 and then slides into the next adjacent recess 301 .

[0034] The first elastic member 500 is formed by bending a metal spring sheet. A V-shaped protrusion 510 is provided on the first elastic member 500. The tip of the V-shaped protrusion 510 can be configured to have a certain arc shape. The V-shaped protrusion 510 is configured to elastically swing on the first elastic member 500 to elastically slide into and out of each recess 301 in sequence. The process of the V-shaped protrusion 510 sliding into and out of each recess 301 is equivalent to the recess 301 applying an external force on the V-shaped protrusion 510, causing the first elastic member 500 to elastically deform.

[0035] In some specific embodiments of the present invention, Figure 2 and Figure 3As shown, an elastic clip 600 is provided on the lamp body 100. A notch 302 is provided on the movable frame 300. The notch 302 is opened on the rod body 310 of the movable frame 300. The elastic clip 600 is configured so that when the notch 302 moves with the movable frame 300 to align with the elastic clip 600, the elastic clip 600 can be engaged in the notch 302 to restrict the movement of the movable frame 300. The elastic clip 600 is also configured so that when the elastic clip 600 is manually toggled, the elastic clip 600 can disengage from the notch 302 so that the movable frame 300 moves completely away from the lamp body 100. The user can manually toggle the elastic clip 600. When the elastic clip 600 is not positioned opposite to the notch 302, the elastic clip 600 can abut against the rod body 310 of the movable frame 300. When the movable frame 300 moves, the elastic clip 600 slides on the surface of the rod body 310. When the movable frame 300 is pulled out relative to the lamp body 100 to a certain position, the elastic clamp 600 engages with the notch 302, restricting further movement of the movable frame 300 and effectively limiting the extension range of the movable frame 300. By manually moving the elastic clamp 600 so that it disengages from the notch 302, the movable frame 300 can be further pulled, either to reset it or to completely pull it away from the lamp body 100.

[0036] Specifically, such as Figure 3As shown, the elastic clamping member 600 includes a second elastic member 610 and a selector 620. The selector 620 is configured so that it can move between a first position and a second position relative to the lamp body 100. The elastic member can be a spring, a shrapnel, etc. The second elastic member 610 is configured so that it drives the selector 620 to move to the second position through elastic force. When the movable frame 300 moves within the range of travel in which the selector 620 is not aligned with the notch 302, the selector 620 remains in the first position and abuts against the movable frame 300. When the movable frame 300 moves, the selector 620 slides relative to the surface of the movable frame 300. When the movable frame 300 moves to the point where the selector 620 is aligned with the notch 302, the second elastic member 610 drives the selector 620 to move to the second position through elastic force. When the selector 620 is in the second position, the selector 620 is engaged with the notch 302. After manually resetting the dial 620 to the first position, the dial 620 will escape from the notch 302. A clamping head 630 is provided on the dial 620. The notch 302 is provided with a first surface 303 and a second surface 304 that are opposite to each other. The first surface 303 and the second surface 304 are spaced apart along the moving direction of the movable frame 300. The first surface 303 is perpendicular to the moving direction of the movable frame 300, and the second surface 304 is inclined to the moving direction of the movable frame 300. In the direction shown in the figure, the movable frame 300 moves up and down, the first surface 303 is horizontally arranged, and the second surface 304 is inclined downward. When the movable frame 300 slides downward, the clamping head 630 can slide into the notch 302 along the second surface 304. When the movable frame 300 continues to move downward, the clamping head 630 abuts against the first surface 303. The clamping head 630 cooperates with the first surface 303 to limit the movable frame 300 from continuing to move downward, that is, to limit the movable frame 300 from completely escaping from the lamp body 100 downward. When the movable frame 300 moves upward, the clamping head 630 can slide out of the notch 302 along the second surface 304. The process of the clamping head 630 sliding into and out of the notch 302 along the second surface 304 does not require manual control of the shifting member 620.

[0037] In some embodiments of the present invention, Figure 1 、 Figure 5 and Figure 6As shown, the lamp body 100 includes a lamp holder 110 and a guide holder 120. The guide holder 120 can be configured in a strip shape. The guide holder 120 can be detachably mounted on the lamp holder 110. The above-mentioned first elastic member 500, second elastic member 610, elastic clip 600, etc. can all be mounted on the guide holder 120. The guide holder 120 is provided with a guide groove 121 along the irradiation direction of the lamp source assembly 200. That is, the guide groove 121 is arranged along the moving direction of the movable frame 300. The movable frame 300 includes a rod body 310, which can be slidably inserted into the guide groove 121. The movement of the movable frame 300 is guided by the guide groove 121. The guide holder 120 can be installed in the lamp holder 110 by plugging. A buckle is provided on the guide holder 120, and the guide holder 120 is fixed to the lamp holder 110 by the buckle for quick installation.

[0038] In some embodiments of the present invention, Figure 1 、 Figure 2 and Figure 5 As shown, the light guide seat 400 is annular. The middle part of the light guide seat 400 is hollow to form a light projection port 410. The end of the rod body 310 of the movable frame 300 is rotatably connected to the inner wall of the light guide seat 400. Among them, a screw 420 is radially penetrated on the light guide seat 400. The screw 420 and the movable frame 300 are connected by a thread. The light guide seat 400 is clamped between the screw 420 and the end of the rod body 310. The outer sleeve of the light guide seat 400 is provided with an outer ring sleeve 700, and the outer ring sleeve 700 is fixed to the light guide seat 400. After the outer ring sleeve 700 is installed, the screw 420 can be covered. The light guide seat 400 is matched and connected to the mounting port on the ceiling through the outer ring sleeve 700.
