[0002] Underground lights are landscape lights buried underground. They are mainly used for lighting and decoration in outdoor squares, lawns, courtyards, parks and other places. Underground lights have a unique design and can usually be well integrated into the ground environment. The structure of an underground light usually includes the lamp body, LED light source, drive circuit and waterproof design. The lamp body is generally made of corrosion-resistant materials, such as aluminum alloy, to ensure the durability and waterproof performance of the lamp.

[0003] In order to simplify the waterproof and dustproof structure of the underground lamp in the prior art and to facilitate the later disassembly and maintenance of the underground lamp, the lamp head part of the lamp body is designed to cover the embedded part, so that the underground lamp will protrude from the ground by the thickness of the lamp head after installation.

[0004] The structure of the underground lamp protrudes a little, which will bring some defects in application. Pedestrians may accidentally touch the lamp while walking, which brings certain safety hazards. At the same time, it is impossible to achieve the original design intention of the underground lamp, which is to integrate with the ground and create an overall and unified beauty.

DETAILED DESCRIPTION

[0032] 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.

[0033] The utility model is further described below in conjunction with embodiments.

[0034] Example:

[0035] The utility model provides an underground lamp that is level with the ground. The main components of the product include an embedded part 10 and a lamp body 20 assembly, wherein the lamp body 20 mainly includes a shell 30 with good dustproof and waterproof properties and a light source component 40. The light source component 40 is consistent with the composition of the underground lamp in the prior art, mainly including an LED chip, a reflective cup and a PCB board for driving the LED chip, and is connected to an external power supply through a wire, which will not be described in detail here.

[0036] The underground lamp of this solution improves the structure of the joint between the lamp body 20 and the embedded part 10, as well as the connection design between the two, so as to ensure that the lamp has good dust and water resistance and is convenient for later disassembly and maintenance, so that the top surface of the lamp body 20, the top surface of the embedded part 10 and the ground are flush. The improved product will be described in detail below.

[0037] Reference Figure 1-6 The structure of this product mainly includes an embedded part 10 and a lamp body 20. The embedded part 10 is provided with a receiving cavity 11 with an open end, and a countersunk groove 12 is provided at the opening. When installing the underground lamp, the embedded part 10 is fixed in the ground in advance by concrete. The shell 30 of the lamp body 20 is movably inserted into the receiving cavity 11, wherein one end of the shell 30 is embedded in the countersunk groove 12, and the outer end surface of the shell 30 is flush with the end surface of the embedded part 10 and also keeps level with the ground plane.

[0038] One end of the shell 30 of the lamp body 20 is sunk and embedded in the countersunk groove 12, so that the end face of the shell 30 is flush with the end face of the embedded part 10 and the ground plane; the design flush with the ground can effectively avoid the safety hazard to pedestrians caused by the protrusion of the existing technology products. At the same time, this product can be integrated with the ground to create an overall and unified aesthetic.

[0039] The lamp 20 is also provided with a retaining member 50 which is an elastic structural member. When the housing 30 is inserted into the accommodating cavity 11, the retaining member 50 is elastically supported between the accommodating cavity 11 and the outer wall of the housing 30, so as to elastically compress and fix the lamp body 20 in the accommodating cavity 11. In this embodiment, the retaining member 50 is preferably a pair of outwardly extending elastic sheets, one end of which is fixed to the housing 30, and the other end of which is outwardly extending and elastically deformable and supported on the surface of the accommodating cavity 11.

[0040] Specifically, in this embodiment, the main body of the embedded part 10 is preferably designed to be a hollow cylinder, and the accommodating cavity 11 is a cylindrical groove that passes through on both sides. The main body of the shell 30 is in the shape of a stepped shaft. Specifically, the shell 30 includes an upper shell 31 and a lower shell 32 that are threadedly connected. The upper shell 31 and the lower shell 32 together form a sealed installation groove, and the installation groove is used to place the light source assembly 40; specifically, the upper shell 31 and the lower shell 32 are connected by pipe threads, and the thread depth is greater than or equal to 10mm. A light outlet 313 is provided at the top of the upper shell 31, and a lens 60 is glued and fixed at the light outlet 313. A wire outlet hole 321 is provided at the bottom of the lower shell 32, and a waterproof connector 70 is fixed at the wire outlet hole 321.

[0041] The countersunk groove 12 of the embedded part 10 is designed to be a tapered groove, and the opening of the accommodating cavity 11 is a conical groove structure. The end surface of the upper shell 31 is provided with an outward-extending supporting portion 311. The top surface of the upper shell 31 is flush with the end surface of the embedded part 10, and the edge of the supporting portion 311 is a conical surface 314 that fits the conical groove. The conical surface 314 on the shell 30 is designed to cooperate with the conical groove, so that the lamp body 20 has a good bearing capacity after being installed at the embedded part 10; in addition, the guiding property of the conical surface 314 is used to realize that when the lamp body 20 is inserted into the accommodating cavity 11, it can be automatically aligned and fit, and the combination is tight without deviation.

[0042] At the same time, in order to facilitate the subsequent maintenance and disassembly of the lamp body 20, a pair of notches 312 are symmetrically opened on the edge of the supporting portion 311. The size of the notch 312 is sufficient to insert the end of a flat-blade screwdriver.

[0043] In order to improve the firmness of the embedded part 10 and the ground, a plurality of annular grooves 13 are evenly distributed along the axial direction of the embedded part 10 on the outer wall thereof. The annular grooves 13 are coaxial with the embedded part 10. When the embedded part 10 is installed, concrete will be filled into the annular grooves 13, so that the embedded part 10 and the ground are tightly interlaced and fixed together. A wire notch 14 is provided at the bottom of the embedded part 10 to facilitate the combination and avoidance with the embedded wire tube.

[0044] It is worth noting that the embedded parts 10 and the shell 30 of this product are made of corrosion-resistant metal or plastic materials.

[0045] 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.
