Description

Technical Field

[0001] This invention relates to a spotlight. Background Technology

[0002] The existing technology, Chinese patent 202020635626.0, describes a ceiling light with adjustable light output direction, including a light shield and a spotlight body. The light shield is fixedly mounted on the ceiling, and the spotlight body is rotatable relative to the light shield. The light shield and the spotlight body are rotatably connected via a rotating connection assembly. The rotating connection assembly includes: a limiting pivot, fixedly mounted relative to the spotlight body and movable synchronously with the movement of the spotlight body; and a tilting slide rail, which has an arc-shaped structure and is fixedly mounted relative to the light shield. The limiting pivot can move within the tilting slide rail to adjust the angle of the spotlight body relative to the light shield. The problem is that the structure is complex and positioning is inconvenient.

[0003] Chinese Patent 202210074532.4 discloses a ceiling spotlight with adjustable beam size, comprising a face ring, a front cover, a rotating ring, a swinging middle cover, and a spotlight body. The upper end of the cup is inserted into the annular body, and a hook engages with a fastener. A hinged frame extends into the annular cover and is hinged together, with the diameter line of the inclined surface and the diameter line of the hinge point on the same vertical plane. A light-emitting cavity extends into the annular cover, and the lower end face of the heat sink is fitted and slidably positioned against the upper end face of the annular cover. The flange of the front cover engages with the countersunk hole at the lower end of the cylindrical part of the face ring, and an elastic device on the annular body engages with the annular guide groove. The front cover, rotating ring, swinging middle cover, and spotlight body rotate together. The problem is that the light source is prone to loosening after swinging and positioning.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a swaying and rotating spotlight includes a light source chip 1 and a bracket 2, an elephant trunk-shaped heat sink 3, a lens 4, a front ring 5, a rotating ring 6, and a face ring 7. The elephant trunk-shaped radiator 3 includes a light source cavity 31 with a lower opening, a hook 32 disposed within the light source cavity 31, a cavity clearance groove 33 disposed at the lower end of the light source cavity, a bearing 34, a rotating shaft 35, a track groove 36, and a heat dissipation body 37. The heat dissipation body 37 extends horizontally at the top of the light source cavity 31. The bearing 35 forms an acute angle with the horizontal plane on the radially inner side of the light source cavity 31 and is opposite to the cavity clearance groove 33. The track groove 36 is closed at both ends. The elephant trunk-shaped radiator 3 adopts this design to reduce the vertical space occupied between the ceiling and the roof panel. The track groove 36 is closed at both ends. The heat dissipation body 37 is provided with heat dissipation grooves. The front ring 5 includes a frustum body 51, an annular edge plate 52, a fastener 53, and an axial stiffener 54. The fastener is arranged around the frustum body 51, and the axial stiffener 54 is provided on the frustum body 51 between the fasteners 53. The frustum body 51 serves as a light guide. The rotating ring 6 includes a sliding rail 61, a sliding positioning element 62, a guide rail 63 located in the upper end, a guide groove 64 with a lower opening, and shaft grooves 65 located on both sides of the guide groove 64; the guide rail 63 and the guide groove 64 are on the same diameter line. The face ring 7 includes a cylindrical body 71, positioning toothed grooves 72 evenly distributed in the circumferential direction, an annular track 73, and a decorative ring plate 74. The light source chip 1 is mounted on the bracket 2, which is fixed to the top plate of the light source cavity 31, and the light source chip 1 is attached to the top plate of the light source cavity 31. The lens 4 is mounted on the truncated cone body 51, which is inserted into the light source cavity 31, and the hook 32 and the fastener 53 are engaged. The upper end of the lens 4 is attached to the bracket 2 and cooperates with the light source chip 1. The light source cavity 31 is inserted into the rotating ring 6, the shaft seat 34 is slidably engaged with the guide groove 64, the two ends of the rotating shaft 35 are rotatably engaged with the shaft groove 65, the guide rail 63 and the track groove 36 are slidably engaged and positioned by friction. The sliding positioning part 62 and the positioning tooth groove 72, the sliding rail 61 and the annular track 73 are engaged.

[0023] like Figure 1 In the indicated state, the guide rail 63 is engaged with the lower end of the track groove 36; after the front ring 5 and the elephant trunk-shaped radiator 3 rotate clockwise together, the guide rail 63 is engaged with the upper end of the track groove 36.

[0025] As a further improvement of the present invention: the guide rail 63 is provided with an annular groove (not marked); It also includes a silicone sleeve 8, one end of which has an annular protrusion (not labeled). The silicone sleeve 8 is mounted on the guide rail 63, with an annular protrusion engaging with an annular groove, and the silicone sleeve 8 being positioned in conjunction with the track groove 36. Positioning is achieved by utilizing the elasticity of the silicone sleeve 8 and the friction between it and the track groove 36; oscillation overcomes the friction, allowing for oscillation.

[0026] As a further improvement of the present invention: the sliding rail 61 includes a clearance hole 611 provided on the lower opening of the rotating ring 6, an elastic plate 612, and an arc-shaped hook portion 613. The arc-shaped hook 613 and the annular track 73 slide together.

[0030] When using this invention, as Figure 1 As shown, the silicone ring 8 is engaged with one end of the track groove 36; holding the handle 55, the front ring 5 and the elephant trunk-shaped radiator 3 are swung clockwise together, and the track groove 36 slides relative to the silicone ring 8. After the rotation is completed, the front ring 5 loses power, and due to the elasticity of the silicone ring and the friction generated by the track groove, it is positioned.

[0031] exist Figure 5 In this state, the hand handle 55, the front ring 5, and the elephant trunk-shaped radiator 3 can rotate together around the Z-axis in a clockwise or counterclockwise direction.

[0032] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
