Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to an angle-adjustable fountain light. Background Technology

[0002] Traditional fountain lights typically employ a fixed-angle installation structure, with the lamp body and support components secured by bolts or clips. This makes it difficult to adjust the illumination angle after installation. Changing the lighting direction requires disassembly and repositioning, a cumbersome process that can easily damage the lamp's structure. Furthermore, existing fountain lights are mostly individual, independent designs, lacking convenient linkage and expansion mechanisms between multiple lamps. When creating continuous light strips or combined shapes, complex connecting components are often required, leading to low installation efficiency and increased costs.

[0003] Therefore, there is an urgent need for a fountain light device with a simple structure, capable of free adjustment of the lamp body at multiple angles and supporting rapid expansion and series connection, in order to meet the dynamic lighting needs and diverse installation scenarios in fountain landscapes. Utility Model Content

[0004] The purpose of this invention is to provide an angle-adjustable fountain light, which has the advantages of simple structure, multi-angle free adjustment of the light body, and support for rapid expansion and series connection.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an angle-adjustable fountain light, including a connecting bracket, and a lamp tube and a lamp sleeve disposed on the connecting bracket. The lamp sleeve is provided with a first through hole and a second through hole spaced apart. The lamp tube is inserted into the first through hole, and the lamp sleeve is inserted into the connecting bracket through the second through hole. A rotating fit structure is provided between the lamp tube and the lamp sleeve, and the rotating fit structure constrains the relative angle between the lamp tube and the lamp sleeve.

[0006] By adopting the above technical solution, the lamp tube can be rotated at any time according to the needs of the usage environment through the rotating mechanism, thereby changing the illumination direction of the lamp tube. This makes it more user-friendly and convenient to use, and the structure is simple. It also allows two lamp tubes to be connected in series, and the two lamp tubes can provide different illumination angles respectively, thereby completing more diverse lighting tasks. In addition, the connection is quick and convenient.

[0007] A further feature of this invention is that the rotating fit structure includes a limiting groove, an elastic element, and a top bead. The limiting groove is evenly distributed circumferentially on the outer wall of the lamp tube. The elastic element is assembled on the lamp sleeve. The top bead is fixedly connected to the end of the elastic element. The top bead and the limiting groove form an elastic abutment. When the lamp tube rotates around its axis, the top bead is circumferentially positioned with respect to the corresponding limiting groove.

[0008] By adopting the above technical solution, when the lamp tube rotates around its axis, the top bead rolls on the slot and makes a "tick" sound. Users can judge the positioning status of the top bead and the slot based on the sound, making the operation simple.

[0009] A further feature of this invention is that: both sides of the lamp cover have rings extending vertically, and the first through hole is formed between the two rings.

[0010] By adopting the above technical solution, the lamp tube is fixed between two rings, and the space between the rings is connected to the outside. The lamp tube has a large heat dissipation area, thus resulting in better heat dissipation.

[0011] A further feature of this invention is that the lamp tube includes a housing, a bracket, an LED, a power supply, and a circuit board. The housing covers the bracket, the LED, the power supply, and the circuit board. The housing is fixedly connected inside the housing. The LED, the power supply, and the circuit board are fixedly connected to the bracket. The LED is electrically connected to the power supply and the circuit board. A light-emitting surface is provided on the outer surface of the bracket, and the light-emitting surface is located at a position corresponding to the optical axis of the LED.

[0012] By adopting the above technical solution, the LED chips, power supply and circuit board are integrated into the housing, resulting in a reasonable layout and compact structure.

[0013] A further feature of this invention is that a first screw cap is inserted into the first through hole, the first screw cap is fixedly connected to the lamp tube, and the first screw cap portion is exposed on the outer surface of the lamp sleeve.

[0014] By adopting the above technical solution, the lamp tube can be rotated by rotating the first cap exposed on the outer surface of the lamp cover, which is simple to operate.

[0015] A further feature of this invention is that: a protrusion is provided on the side of the housing near the first cap, and a first groove corresponding to the protrusion is provided on the first cap; the protrusion is engaged in the first groove to fix the first cap to the lamp tube.

[0016] By adopting the above technical solution, the lamp tube is fixedly connected to the first screw cap by inserting the protrusion into the first groove. The structure is simple and easy to implement.

[0017] A further feature of this invention is that the lamp tube sidewall is provided with a limiting rib, the lamp sleeve is provided with a slot, the limiting rib is placed in the slot, and defines a displacement path that constrains the lamp tube to rotate along its axial direction.

[0018] By adopting the above technical solution, when the limiting rib abuts against the empty groove, it restricts the rotation direction of the lamp tube on one side. This design avoids excessive rotation of the lamp tube due to human error, which could lead to the internal wires of the lamp tube getting tangled and cause safety hazards, thus improving safety.

[0019] A further feature of this invention is that the connecting bracket has a horizontal beam and a vertical beam, the two ends of the horizontal beam are respectively inserted into the second through holes of the two lamp sleeves, and the horizontal beam and the vertical beam are integrally formed to form an orthogonally intersecting T-shaped structure.

[0020] By adopting the above technical solution, two lamps can work together to complete the lighting task, and the two lamps can provide different lighting angles, thereby completing more diverse lighting tasks.

[0021] A further feature of this invention is that a second cap is inserted into the first through hole, and a switch button and a charging port are provided on the end face of the second cap. The switch button and the charging port are electrically connected to the power supply and the circuit board.

[0022] By adopting the above technical solution, the switch button, power supply, circuit board, and LED beads are located in the same circuit for controlling the LED bead switching; the charging port is located in the same circuit for charging the power supply. The structure is simple and the switching and charging operations are convenient.

[0023] In summary, this utility model has the following beneficial effects: The lamp sleeve has a first through hole and a second through hole spaced apart. The lamp tube is inserted into the first through hole, and the lamp sleeve is inserted into the connecting bracket through the second through hole. There is a rotating fit structure between the lamp tube and the lamp sleeve. The rotating fit structure constrains the relative angle between the lamp tube and the lamp sleeve. It has the effects of simple structure, free adjustment of the lamp body at multiple angles and support for rapid expansion and series connection. Attached Figure Description

A rotating fit structure is provided between the lamp tube 1 and the lamp sleeve 2, and the rotating fit structure constrains the relative angle between the lamp tube 1 and the lamp sleeve 2. The lamp tube 1 is movably installed inside the lamp sleeve 2. The two first through holes 21 form a movable area for the lamp tube 1. Within this movable area, the lamp tube 1 rotates circumferentially along the central axis of the two first through holes 21. According to the needs of the usage environment, the lamp tube 1 can be rotated at any time through the rotation and engagement mechanism, thereby changing the illumination direction of the lamp tube 1. This makes it more user-friendly, convenient, and simple in structure. The second through holes 22 of the two lamp sleeves 2 are connected in series through the connecting bracket 313, thereby connecting the two lamp tubes 1 in series. The two lamp tubes 1 can provide different illumination angles, thereby completing more diverse lighting tasks. For example, the two lamp sleeves 2 can be connected in series through the connecting bracket 313, and the illumination angle of one lamp tube 1 can be adjusted forward, while the illumination angle of the other lamp tube 1 can be adjusted backward. This will allow illumination in both the front and rear directions.
