[0002] The demand for underwater lighting devices is growing for underwater lighting applications such as ships, bridges, and swimming pools. However, traditional underwater lighting devices often suffer from voltage instability, resulting in reduced light efficiency and high energy consumption, limiting their application and effectiveness. Most of these devices use conventional waterproofing with chips to control voltage drop, which lacks waterproof performance and is easily damaged by water ingress and short circuits. Utility Model Content

[0003] (1) Technical problems solved

[0004] In response to the shortcomings of the existing technology, the utility model provides a low-voltage, no-voltage-drop waterproof LED light strip for underwater use. It uses TPU waterproof material as the outer protective material to improve the waterproof effect, and uses a flat widened conductive tape as a carrier. The lamp beads are connected in parallel with each other, and no chip control is required. The long-distance voltage loss is low, thereby solving the problem that most ordinary waterproof lights are used with chip control voltage drop, which lacks waterproof performance and is easily damaged by water ingress and short circuit.

[0005] (2) Technical solution

[0006] To achieve the above, TPU waterproof material is used as the outer protective material to improve the waterproof effect, and a flat widened conductive tape is used as the carrier. The lamp beads are connected in parallel, and no chip control is required. The long-distance voltage loss is low. The specific technical solutions adopted by this utility model are as follows:

[0007] A low-voltage, no-voltage-drop waterproof LED light strip for underwater use, comprising a housing, a light strip, a housing cover, and a waterproof connector. The housing cover is inserted into the housing, the light strip is arranged inside the housing, and the waterproof connector is sealed on both sides of the housing. The housing is provided with guide rails and limit blocks, the guide rails are symmetrically arranged on both sides of the interior of the housing, the limit blocks are located above the guide rails, and the guide rails and the limit blocks form a guide groove. Insert blocks that cooperate with the guide groove are provided on both sides of the housing cover. The light strip comprises a potting circuit board and lamp beads fixed on the potting circuit board, and an array of lamp beads is displayed on the potting circuit board.

[0008] Furthermore, the shell and the shell cover are both sealed with TPU outer protective material.

[0009] Furthermore, the light bar is a flat and widened conductive strip, and the lamp beads are connected in parallel to emit light in a multi-color combination.

[0010] Furthermore, a waterproof coating is provided on the waterproof joint.

[0011] Furthermore, the guide groove and the shell cover are tightly inserted and fitted.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides a low-voltage, no-voltage-drop, waterproof LED light bar for underwater use, which has the following beneficial effects:

[0014] The housing's guide rails and stoppers form a guide groove that fits snugly into the housing cover. Waterproof connectors are sealed on both sides of the housing, creating a mounting cavity for the light strip. Both the housing and cover are sealed with TPU protective material. This achieves zero voltage drop per meter, or minimal voltage drop around a meter without affecting the light strip's luminous effect. The light strip is a flat, widened conductive strip, with the lamp beads connected in parallel to produce a variety of color combinations. This eliminates the need for chip control and offers the advantages of low voltage loss over long distances. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] According to an embodiment of the present invention, a low-voltage, no-voltage-drop, waterproof LED light bar for underwater use is provided.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1 -shown, according to an embodiment of the present invention, a low-voltage, no-voltage-drop waterproof LED light strip for underwater use comprises a housing 1, a light strip 2, a housing cover 3, and a waterproof connector 4. The housing cover 3 is inserted into the housing 1, the light strip 2 is disposed inside the housing 1, and the waterproof connector 4 is sealed on both sides of the housing 1. The housing 1 is provided with guide rails 11 and limit blocks 12. The guide rails 11 are symmetrically disposed on both sides of the interior of the housing 1, and the limit blocks 12 are located above the guide rails 11. The guide rails 11 and the limit blocks 12 form a guide groove. Insert blocks 31 are provided on both sides of the housing cover 3 to cooperate with the guide groove. The light strip 2 comprises a potted circuit board 21 and lamp beads 22 fixed to the potted circuit board 21. The array of lamp beads 22 is displayed on the potted circuit board 21. This improves the waterproof effect.

[0025] In one embodiment, the housing 1 and the housing cover 3 are both sealed with TPU outer protective material, which can achieve no pressure drop at 10 meters and little pressure drop at around 20 meters without affecting the lighting effect of the light bar.

[0026] In one embodiment, the light bar 2 is a flat widened conductive strip, and the lamp beads 22 are connected in parallel to emit light in multiple colors, thereby achieving the goal of eliminating the need for chip control and reducing voltage loss over long distances.

[0027] In one embodiment, a waterproof coating is provided on the waterproof joint 4 .

[0028] In one embodiment, the guide groove is tightly inserted and fitted with the housing cover 3, thereby improving the waterproof effect.

[0029] Working Principle: The guide rails 11 of the housing 1 and the stoppers 12 form a guide groove, which fits snugly into the housing cover 3. Waterproof connectors 4 are sealed on both sides of the housing 1, creating a mounting cavity for the light strip 2. Both the housing 1 and the housing cover 3 are sealed with TPU outer protective material. This ensures no voltage drop over a distance of 10 meters, and minimal voltage drop around 20 meters without affecting the light strip's luminous effect. The light strip 2 is a flat, widened conductive strip, and the lamp beads 22 are connected in parallel to produce a multi-color light pattern. This eliminates the need for chip control and offers the advantages of low voltage loss over long distances.
