Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a telescopic rotating focusing spotlight. Background Technology

[0002] Currently, ceiling lights include two types: downlights and spotlights. Downlights are embedded in the ceiling, and their light source is not adjustable. They have a wider beam, usually 60° to 120°, suitable for large-area uniform lighting, but they can only illuminate in one direction. Spotlights, on the other hand, are installed on the ceiling and can be moved and rotated, so their light source direction can be freely adjusted. However, their beam is narrower, usually 15° to 45°, suitable for local lighting and highlighting specific objects. Therefore, the direction and position of the beam need to be frequently adjusted to achieve the desired lighting effect. Both types of lights have very prominent advantages and disadvantages.

[0003] Later, lighting fixtures combining the two appeared, such as the Chinese patent with authorization announcement number CN206973387U, which discloses a stepless focusing LED ceiling light. This invention relates to the field of LED ceiling lights. Ceiling springs are installed at both ends of the outer ring, and the lower ends of the inner ring are fixedly connected to both ends of the outer ring via countersunk screws. An LED light source is installed inside the LED mounting base, and a convex lens is installed at the lower end of the LED mounting base. The lower part of the LED mounting base is fixedly connected to a focusing screw mechanism and installed inside the inner ring. A spring fixing base is fixed to the LED mounting base by a telescopic spring, and both ends of the spring fixing base are fixedly connected to the upper sides of the inner ring via set screws. A back cover is installed on top of the spring fixing base. By designing a screw-type focusing mechanism using die-cast aluminum alloy technology compared to CNC machining, the product production cost is reduced. Using a convex lens, the focusing mechanism allows for stepless adjustment of three commonly used angles: 12, 24, and 36 degrees. This stepless adjustment makes operation more convenient and allows for multiple uses with a single light. However, the extension distance of this type of lamp is controlled by a spring, so the control is not precise enough.

[0004] Therefore, those skilled in the art are dedicated to developing a telescopic rotary focusing spotlight capable of precisely controlling the telescopic length. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a telescopic rotary focusing spotlight that can precisely control the telescopic length.

[0006] To achieve the above objectives, this utility model provides a telescopic rotating focusing spotlight, including a base and a lamp head mounted on the base. A light source is installed inside the lamp head, and a focusing mechanism is installed at the front end of the lamp head in front of the light source. Ceiling-connecting springs are respectively provided on both sides of the outer surface of the base. The base is an axially hollow tubular structure. One end of a rotating seat is hinged to the rear end of the lamp head, and a telescopic platform is fixedly connected to the other end of the rotating seat. The telescopic platform is connected to the base via an axial telescopic mechanism. The lamp head can extend and retract via the axial telescopic mechanism, rotate 90 degrees to one side via the rotating seat, and adjust the illumination range of the lamp via the focusing mechanism. Thus, this lamp simultaneously performs three functions: telescopic, rotating, and focusing.

[0007] The axial telescopic mechanism includes a sliding groove that extends axially from the inner side wall of the base, and a slider that matches the sliding groove is provided on the side of the telescopic platform; the bottom of the sliding groove is provided with a plurality of axially extending adjusting grooves, and the slider is provided with elastic locking teeth that can be embedded in the adjusting grooves. Due to the elastic locking teeth and adjusting grooves, the telescopic length can be precisely adjusted to meet various lighting needs.

[0008] Furthermore, the elastic teeth are located at the lower end of the elastic strip that can swing freely at the lower end, and the upper end of the elastic strip is fixedly connected to the upper end of the slider. The structure is simple and easy to control.

[0009] Furthermore, the lamp head includes a lamp tube and a lens ring installed at the front end of the lamp tube and axially movable. A lens is fixedly installed inside the lens ring. The focusing mechanism includes an adjusting cylinder sleeved and fixed inside the lamp tube. The adjusting cylinder has a spirally forward adjusting groove on its side wall. The lens ring has an adjusting block embedded in the adjusting groove on its side wall. Due to the cooperation between the adjusting block and the adjusting groove, the lens ring can spiral forward or backward, thus adjusting the focal length and the illumination range.

[0010] Furthermore, the top of the telescopic platform is provided with an axially penetrating heat dissipation hole to facilitate heat dissipation of the lamps.

[0011] Furthermore, a circumferentially rotating adjusting ring is fixedly connected to the front end of the base. A ceiling fixing ring that can rotate circumferentially but cannot move axially is sleeved on the circumferentially rotating adjusting ring. The ceiling connecting spring is installed on the outer side wall of the ceiling fixing ring. In actual installation, the ceiling connecting spring is connected to the ceiling. The structure is simple and the installation is convenient and quick.

[0012] Furthermore, the inner wall of the ceiling fixing ring is provided with a ring of circumferentially arranged circumferentially rotating positioning teeth, and the circumferentially rotating adjusting ring is provided with elastic protrusions that can be embedded in the circumferentially rotating positioning teeth. Through the cooperation of the elastic protrusions and the circumferentially rotating positioning teeth, the circumferentially rotating adjusting ring can rotate precisely, so that the illumination direction of the lamp head can be precisely controlled after the lamp head is extended.

[0013] Furthermore, the front end of the base is provided with at least two upwardly extending fixed posts, and the circumferential rotation adjustment ring is provided with a fixed sleeve that is sleeved on the fixed posts. The structure is simple and convenient for fixed installation.

[0014] Furthermore, the upper end of a T-shaped hinge frame is fixedly connected to the rear end of the lamp head, and the lower end of the T-shaped hinge frame is connected to one end of the rotating seat through a hinge shaft. The structure is simple and convenient for fixed installation.

[0015] Furthermore, the upper end of the T-shaped hinge frame is provided with two symmetrical connecting ears, and the connecting ears are provided with screws for connecting to the lamp holder. The structure is simple and convenient for fixing and installation.

[0016] Furthermore, a heat sink is provided at the rear end of the lamp head to facilitate heat dissipation.

[0017] The beneficial effects of this utility model are as follows: The telescopic rotating focusing spotlight of this utility model includes a base and a lamp head mounted on the base. A light source is installed inside the lamp head, and a focusing mechanism is installed at the front end of the lamp head in front of the light source. Ceiling connecting springs are respectively provided on both sides of the outer surface of the base. The base is an axially hollow tubular structure. One end of a rotating seat is hinged to the rear end of the lamp head, and a telescopic platform is fixedly connected to the other end of the rotating seat. The telescopic platform is connected to the base through an axial telescopic mechanism. The lamp head can extend and retract through the axial telescopic mechanism, and the lamp head can rotate 90 degrees to one side through the rotating seat. The focusing mechanism can adjust the illumination range of this lamp. Thus, this lamp has three major functions: telescopic, rotating, and focusing. The circumferential rotating adjustment ring can rotate 360 ​​degrees or precisely rotate a certain angle, so that the illumination direction of the lamp head can be precisely controlled when the lamp head is extended. Furthermore, since the axial telescopic mechanism includes an adjusting tooth groove, the telescopic length can be precisely adjusted to meet diverse lighting needs. Attached Figure Description
