DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model is further described below in conjunction with embodiments.

[0033] Example:

[0034] The utility model provides a novel spotlight rotation structure. This solution improves the rotation structure of the existing spotlight so that the light irradiation angle and irradiation range of the spotlight can be conveniently and flexibly adjusted, so that non-professional users can also easily adjust the rotation operation according to scene requirements.

[0035] The improved structure of the spotlight of this solution mainly includes a reflector 10 for reflecting light, a lamp holder 20 for installing an LED light source 30 and dissipating heat, and a lamp housing 40 for fixing on the ceiling, and an additional plastic limit frame 50 is added in this solution. The functions of the connection of several components will be specifically described below:

[0036] The improvement of the reflector 10 is the core component for realizing rotation adjustment. Of course, a hemispherical reflective surface is formed on the inner side of the reflector 10. The reflective surface is used to reflect the light of the LED light source 30 to a designated area or object to form different illumination ranges. In order to realize the rotation function, the present solution realizes the inclined division of the upper and lower sides of the first cover body 11 and the second cover body 12 by dividing the reflector 10 into a first cover body 11 and a second cover body 12. The dividing surface 13 of the first cover body 11 and the second cover body 12 is a circular surface, and the circular surface is inclined to the radial plane of the reflective surface.

[0037] The first cover 11 located at the upper side is provided with a light-transmitting hole 14, and the light of the LED light source 30 can be emitted through the light-transmitting hole 14; the first cover 11 and the second cover 12 can rotate relative to each other along the axis of the dividing surface 13. The lamp holder 20 is detachably connected to the first cover 11, and the lamp holder 20 has the LED light source 30 built therein. The LED light source 30 is coaxially arranged on the upper side of the light-transmitting hole 14, and the lamp holder 20 follows the first cover 11 to rotate relative to the second cover 12.

[0038] In the present embodiment, in order to facilitate the user to operate the rotation of the first cover body 11 and its rotation following component, the first cover body 11 is designed to be provided with an open groove 19 on one side of the reflective surface, and the position of the groove 19 deviates from the axis of the dividing surface 13. Preferably, the shape of the groove 19 is designed to be a straight groove 19, so that the user can use a straight-head screwdriver to insert into the rear groove 19 and then drag and rotate it, and the rotation adjustment is convenient, flexible and labor-saving.

[0039] Crucially, in the design, the axis of the light-transmitting hole 14 is distributed at a certain angle to the axis of the dividing surface 13. In the present embodiment, the suitable angle is preferably between 10-14°. In this way, the eccentric design of the light-transmitting hole 14 relative to the rotation center of the first cover body 11 and the second cover body 12 is one of the bases for synchronously driving the lamp holder 20 and the LED light source 30 by rotating the first cover body 11, thereby realizing a change in the light irradiation angle of the LED light source 30.

[0040] The product is manufactured by tilting and dividing the reflector 10 into a first cover body 11 and a second cover body 12 which can rotate relative to each other, and the first cover body 11 is provided with a light-transmitting hole 14 which deviates from its rotation center, and the LED light source 30 is coaxially distributed with the light-transmitting hole 14. At the same time, the base with the LED light source 30 is designed to rotate together with the first cover body 11, so that the user can drive the base + LED light source 30 to rotate by rotating the first cover body 11, so that the light can be emitted at different angles and reflected by the reflecting surface, thereby realizing the adjustment of the light irradiation angle and irradiation range of the lamp; in addition, because the LED light source 30 moves synchronously with the light-transmitting hole 14 in the rotating structure design, the light emitted by the LED light source 30 will not be blocked by the internal structure of the lamp, the light spot is complete, and the light efficiency is high.

[0041] The specific implementation method of this scheme will be described below:

[0042] In order to realize the relative rotation function of the first cover body 11 and the second cover body 12 along the axis of the dividing surface 13, in the present embodiment, the first cover body 11 is preferably a moving part, wherein the second cover body 12 is a fixed part, and in the installation and fixing design of the second cover body 12, a snap-fit ​​groove 41 is provided on the inner side of the lamp housing 40, and a first snap 15 is fixed near the lower side of the second cover body 12, and is fixedly snapped in the lamp housing by the first snap 15, wherein in the present embodiment, the second cover body 12 is tightly fitted in the snap-fit ​​groove 41 by the first snap 15, and when the first cover body 11 is rotated, the second cover body 12 remains fixed on the lamp housing 40.

[0043] Since the dividing surface 13 separates the first cover body 11 and the second cover body 12, so that the two are only in surface contact, as a complete product, it is necessary to design a rotation connection between the two to prevent them from falling off. The existing structure is known: the first cover body 11 is fitted with the second cover body 12 at the dividing surface 13, and the fitting dividing surface 13 and the second cover body 12 generate relative rotation.

[0044] Reference Figure 1-8 This solution mainly uses an additional limit frame 50 to achieve the rotational connection between the two. By coaxially arranging the limit frame 50 on the outside of the dividing surface 13, the limit frame 50 rotationally connects the first cover body 11 and the second cover body 12 together.

[0045] Specifically, the main body of the limit frame 50 is a ring body with an inverted L-shaped vertical cross section. A second annular buckle 16 is fixedly provided on the outer ring of the dividing surface 13 of the second cover body 12. A plurality of anti-trip buckles 51 are distributed on the lower inner wall of the limit frame 50 and are slidably engaged with the second buckle 16. The limit frame 50 at the corresponding position of the anti-trip buckle 51 is provided with a process notch for deformation of the anti-trip buckle 51 during engagement. At the same time, the upper side of the limit frame 50 is pressed against the surface of the first cover body 11. The first cover body 11 followed by the limit frame 50 rotates synchronously. Specifically, the surface of the first cover body 11 is provided with a circumference of a tooth 17 with the axis of the dividing surface 13 as the center. The limit frame 50 is provided with a slot 52 corresponding to the tooth 17. When the limit frame 50 is pressed against the surface of the first cover body 11, the tooth 17 is correspondingly engaged in the slot 52 to limit the rotational freedom of the limit frame 50.

[0046] After the limiting frame 50 rotates synchronously with the first cover 11, it is necessary to continue to realize that the lamp holder 20 + LED light source 30 rotates synchronously with the first cover 11. In this embodiment, a plurality of third buckles 53 are fixed on the circumference of the limiting frame 50, and the lamp holder 20 is provided with a buckle hole 21 matching the third buckle 53, and the buckle fits to fix the lamp holder 20 on the limiting frame 50. In this way, the lamp holder 20 + LED light source 30 and the limiting frame 50 rotate synchronously with the first cover 11.

[0047] In addition, in order to prevent excessive unidirectional rotation and the risk of the lamp's wires being twisted and broken, a limit block 54 is preferably fixed on the outer wall of the limit frame 50, and a limit rib 18 is fixed on the second cover body 12. When the first cover body 11 drives the limit frame 50 to rotate around the axis of the dividing surface 13 for one circle, the limit block 54 contacts the limit rib 18, limiting the limit frame 50 from continuing to rotate in the same direction, that is, limiting the first cover body 11 and its rotation following components to rotate only within 360°.

[0048] In this embodiment, a pair of mounting brackets 42 for fixing to the ceiling are symmetrically fixed on the lamp housing 40. The mounting brackets 42 are preferably designed to be elastically deformable thin-walled parts. The protruding parts on both sides of the thin-walled parts can be compressed and deformed inward when passing through the mounting holes, and automatically elastically recover after passing through the mounting holes to complete the installation. Compared with traditional spring-type mounting brackets 42, the operation is simpler and the risk of pinching fingers can be effectively avoided.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
