[0026] A mini underground lamp according to an embodiment of the present specification is described in detail below with reference to the accompanying drawings. Figure 1A structural schematic diagram of a small underground lamp according to an embodiment of the present specification is shown. The small underground lamp according to the embodiment of the present specification includes a lamp tube 1 and a lamp shell 2 which is sleeved on one end of the lamp tube 1. A light source assembly 3 is fixed inside the lamp tube 1. A light-transmitting assembly 4 is provided between the light source assembly 3 and the lamp shell 2. A step surface 11 for contacting with the light source assembly 3 is provided inside the lamp tube 1. The light source assembly 3 is located between the step surface 11 and the light-transmitting assembly 4. An elastic clip 31 is provided on the side of the light source assembly 3. When the bottom surface of the light source assembly 3 contacts the step surface 11, the elastic clip 31 can be inserted into a groove 12 provided on the inner wall of the lamp tube 1. Due to its size limitation, the small underground lamp has high requirements for the circuit design of the internal light source circuit board, and is not conducive to the maintenance and replacement of internal parts. In the embodiment of this specification, the fixing method of the light source assembly 3 is changed from the original bolt fixing to elastic clamp fixing. The elastic clamp 31 is an elastic fastener, which is engaged with other structures through the elasticity generated by its own deformation. The elastic clamp 31 in the embodiment of this specification is a structure that can be engaged with the groove 12, such as a clip and an elastic block. On the one hand, the light source assembly 3 limits the position of the bottom surface of the light source assembly 3 through the step surface 11, and on the other hand, the light source assembly 3 is fixed in the lamp tube 1 through the elastic clamp 31 on the side. The connection stability is good and the installation is simple. There is no need to insert bolts to fix it. Just push the light source assembly 3 to the step surface 11. In addition, the elastic clamp 31 is inserted into the groove 12 to reserve more space for the light source assembly 3, and the expansion and debugging of the light source assembly 3 are more convenient.

[0027] Specifically, the elastic clip 31 is sleeved on the surface of the light source assembly 3. The sleeved arrangement makes the contact area between the elastic clip 31 and the light source assembly 3 larger, the connection between the elastic clip 31 and the light source assembly 3 is more secure, and when the elastic clip 31 undergoes elastic deformation, the force on the light source assembly 3 is more uniform, and the light source assembly 3 is fixed more stably.

[0028] In one embodiment, Figure 2 , Figure 3As shown, the elastic clamp 31 leaves a notch in the circumferential direction of the light source assembly 3, and the inner wall of the lamp tube 1 is provided with a protrusion 13 whose bottom surface is the same size as the notch and whose side is parallel to the inner wall of the lamp tube 1, and the groove 12 is formed between the protrusion 13 and the step surface 11. When installing the light source assembly 3, first align the notch with the protrusion 13, then push the light source assembly 3 into the lamp tube 1 until the bottom surface of the light source assembly 3 contacts the step surface 11, rotate the light source assembly 3, so that a part of the elastic clamp 31 is stuck by the groove 12, and the light source assembly 3 is installed. When disassembling, the operation is reversed, first rotate the light source assembly 3, and then the light source assembly 3 can be taken out when the notch is aligned with the prime protrusion 13. This embodiment not only meets the installation stability, but also the steps of fixing and disassembling the light source assembly 3 are convenient and flexible. The upper surface of the light source assembly 3 is also provided with a slot body for cooperating with a rotating tool to drive the light source assembly 3 to rotate, and the rotating tool is a tool such as a screwdriver that can be inserted into the slot body to drive the light source assembly 3 to rotate.

[0029] The bottom surface size of the light source assembly 3 is larger than the top surface size. The bottom surface of the light source assembly 3 completely covers the step surface 11, so that the bottom surface side is in contact with the inner wall of the lamp tube 1, further increasing the connection stability of the light source assembly 3; the bottom surface size of the light source assembly 3 is larger than the top surface size, which, on the one hand, reduces the friction between the light source assembly 3 and the inner wall of the lamp tube 1, making it easier to disassemble and rotate, and on the other hand, reserves a certain space for the elastic clamp 31, so that the elastic deformation of the elastic clamp 31 is not easy to be excessive, and the service life is longer, and it is more labor-saving when installing the light source assembly 3.

[0030] The light source assembly 3 includes a bottom plate, a waterproof shell, a power supply and a lamp group. The waterproof shell is arranged on the bottom plate, and the power supply and the lamp group are arranged in the space formed by the waterproof shell and the bottom plate, so that they are not easily damaged by water seepage. The bottom surface size of the waterproof shell is smaller than that of the bottom plate, and a certain space is also reserved for the elastic clamp 31. The side surface of the bottom end of the waterproof shell is perpendicular to the bottom plate, and the elastic clamp 31 is sleeved on the side surface of the bottom end of the waterproof shell, and the side surface is perpendicular to the bottom plate, so as to increase the stability of the sleeve connection, and the elastic clamp 31 is not easy to fall off.

[0031] In addition, the light-transmitting component 4 is a hollow cylindrical glass with an opening on the lower surface. The side of the light-transmitting component 4 matches the space formed by the side of the light source component 3 and the inner wall of the lamp tube 1, which rationally utilizes the reserved space of the light source component 3 and further reduces the occupied space inside the lamp tube 1. At the same time, the light source component 3 and the light-transmitting component 2 support each other to increase structural stability.

[0032] In another embodiment, the elastic clamp 31 is a spring clip, and the bottom of the spring clip is movably connected to the side of the light source assembly 3. The spring clip usually includes a metal sheet that can undergo elastic deformation, and the two ends of the elastic sheet are respectively fixed to the surface of the light source assembly 3, so that the middle of the metal sheet is compressed and arched. At this time, the middle of the elastic sheet will be deformed after being squeezed by the outside. The spring clip in this embodiment is a columnar structure, and the bottom of the spring clip is movably connected to the side of the light source assembly 3. When the spring clip is subjected to a force in the circumferential direction of the light source assembly 3, it can flip to the side of the light source assembly 3. Figure 4 , at which time the retaining spring can enter the lamp tube 1 along with the light source assembly 3; when the retaining spring enters the lamp tube 1 and is aligned with the groove 12 in the horizontal direction, a part of the retaining spring contacts the inner wall of the groove 12, and the light source assembly 3 is rotated, and the retaining spring generates friction with the inner wall of the lamp tube 1, which can drive the retaining spring to flip to Figure 5 The position shown in the figure, at this time, a part of the retaining spring is locked in the groove 12, preventing the light source assembly 3 from being pulled out of the lamp tube 1, Figure 5 The dotted line portion in the figure is the portion where the clip is inserted into the groove 12. When the light source assembly 3 needs to be disassembled, the light source assembly 3 is rotated in the reverse direction, and the clip is turned over again. Figure 4 The light source assembly 3 can be pulled out of the lamp tube 1 at this time. This embodiment does not need to set the notch, nor does it need to align the protruding piece 13. The light source assembly 3 can be installed and removed simply by rotating, which is more convenient and flexible. Multiple clips can be provided, and the multiple clips are evenly distributed around the light source assembly 3, and the distribution spacing is sufficient not to interfere with the flipping process of each clip.
