Description

Technical Field

[0001] This utility model belongs to the field of buried light technology, specifically relating to a buried light with adjustable light source. Background Technology

[0002] In-ground lights are a common type of lighting and decorative fixture used in lawns, squares, and other similar locations. Conventional in-ground lights typically consist of a housing, a lamp body, and a fixing screw. The lamp body is usually fixed inside the housing by the fixing screw. While this meets general usage needs, the fixed light source—meaning the illumination direction and range are fixed—cannot be adjusted as required. When different illumination directions are needed, the entire structure must be assembled at different angles, which limits the applicability and ease of use of the in-ground light, thus restricting its practicality. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable in-ground light with a reasonable structural design that improves ease of use.

[0004] The technical solution to achieve the purpose of this utility model is an adjustable ground light, including a housing and a lamp body disposed in the housing. The lamp body includes a lamp holder, a light source plate and a light-transmitting plate. A semi-circular protrusion is provided on the lamp holder, and an arc-shaped groove is provided in the middle of the bottom surface of the light source plate. A toggle rod is fixed on the arc-shaped groove.

[0005] The semi-circular protrusion is provided with an arc-shaped actuation groove;

[0006] The arc-shaped groove is attached to the arc-shaped surface of the semi-circular protrusion, and the actuating rod passes through the arc-shaped actuating groove and extends out of the lamp holder;

[0007] The lever moves the light source plate on the semi-circular raised arc surface to adjust the angle.

[0008] A further preferred embodiment is that the actuating support rod is provided with a disc-shaped locking nut;

[0009] The actuating support rod is actuated and locked in place by a disc-shaped locking nut.

[0010] A further preferred embodiment is that a rubber sleeve is provided between the actuating support rod and the lamp holder, and both ends of the arc-shaped actuating groove are inside the rubber sleeve.

[0011] A further preferred embodiment is that the width of the arc-shaped groove is less than the length of the arc-shaped edge of the semi-circular protrusion.

[0012] A further preferred embodiment is that the lamp body is disposed within the housing and fixed by screws.

[0013] A further preferred embodiment is that the lamp holder has several heat dissipation fins on its side wall.

[0014] This utility model has positive effects: its structure is reasonably designed. By setting a semi-circular protrusion and an arc-shaped groove, and by moving the support rod within the arc-shaped groove, the light source plate moves on the arc-shaped surface of the semi-circular protrusion, thereby adjusting the angle of the light source. After adjustment, the lamp body and the outer shell can be fixed. This improves the convenience and effectiveness of adjustment, as well as its reliability. It can meet the illumination needs of different directions, thus expanding its applicability and making it highly practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] See Figures 1 to 2As shown, an adjustable in-ground light includes a housing 1 and a lamp body 2 disposed within the housing. In this embodiment, the lamp body is disposed within the housing and fixed by screws. The housing is a conventional structure of the prior art and is therefore not described in detail, only its application is described. The lamp body includes a lamp holder 21, a light source plate 22, and a light-transmitting plate 23. In this embodiment, the lamp holder and light-transmitting plate are conventional structures of the prior art and are therefore not described in detail. The lamp holder has a semi-circular protrusion 3, and the bottom surface of the light source plate has an arc-shaped groove 4 in the center. A lever 5 is fixed on the arc-shaped groove. The semi-circular protrusion is mainly used for adjustment and guidance, ensuring the convenience and effectiveness of angle adjustment. Furthermore, by levering the lever, the light source plate can be guided and translated on the arc-shaped surface of the semi-circular protrusion, ensuring the effectiveness and reliability of the translation, and also improving the convenience of adjusting the light source plate, making it highly practical.

[0022] Furthermore, the semi-circular protrusion is provided with an arc-shaped actuating groove 6; during assembly, the arc-shaped groove is attached to the arc-shaped surface of the semi-circular protrusion, and the actuating rod passes through the arc-shaped actuating groove and extends out of the lamp holder; the actuating rod drives the light source plate to move on the arc-shaped surface of the semi-circular protrusion to complete the angle adjustment. The arc-shaped actuating groove mainly realizes the adjustment range of the actuating rod, improving the convenience and effectiveness of adjustment.

[0023] Furthermore, in practical applications, a disc-shaped locking nut 7 is provided on the actuating support rod; the actuating support rod is actuated and locked in place by the disc-shaped locking nut. This structure ensures the stability and reliability of the adjusted position.

[0024] In practical applications, a rubber sleeve 8 is provided between the actuating support rod and the lamp holder, and both ends of the arc-shaped actuating groove are inside the rubber sleeve. This structure improves the sealing and waterproofing performance without affecting the normal actuation operation of the actuating rod. The rubber sleeve is conical, with its edge fixed to the lamp holder and its top fixed to the actuating support rod.

[0025] Furthermore, the width of the arc-shaped groove is less than the length of the arc-shaped edge of the semi-circular protrusion. Several heat dissipation fins 9 are provided on the side wall of the lamp holder. This improves heat dissipation effectiveness and reliability, making it highly practical.

[0026] This utility model has positive effects: its structure is reasonably designed. By setting a semi-circular protrusion and an arc-shaped groove, and by moving the support rod within the arc-shaped groove, the light source plate moves on the arc-shaped surface of the semi-circular protrusion, thereby adjusting the angle of the light source. After adjustment, the lamp body and the outer shell can be fixed. This improves the convenience and effectiveness of adjustment, as well as its reliability. It can meet the illumination needs of different directions, thus expanding its applicability and making it highly practical.

[0027] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0028] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
