[0033] The utility model will be described further below in connection with the drawings and embodiments.

[0034] Figure 1 The structure diagram of the LED wall washing lamp applied to underwater provided by an exemplary embodiment of the utility model is shown, Figure 2 The cross-section structure diagram of the LED wall washing lamp applied to underwater provided by an exemplary embodiment of the utility model is shown, the LED wall washing lamp applied to underwater comprises: a shell 1 and an LED photoelectric module 4, the shell 1 is long strip H-shaped, the both ends are sealed and covered with end cover assembly 2, which comprises the first cavity 11 constituting H-shaped and the second cavity 12 located below the first cavity 11, the top of the first cavity 11 is sealed and covered with tempered glass cover plate 3, and the bottom of the second cavity 12 is open; the LED photoelectric module 4 is installed in the containing space formed by the first cavity 11, the end cover assembly 2 and the tempered glass cover plate 3, and is isolated from the outside by the way of pouring sealing glue 5.

[0035] In some embodiments, the sealing glue 5 is silicone AB glue (mainly composed of silicone rubber, which can provide good thermal conductivity and insulation sealing effect. It is very suitable for potting operation, such as LED module, LED lamp and electronic parts. The material of silicone AB glue after curing is relatively soft, which can effectively eliminate mechanical stress and play the role of shock protection. In addition, it has excellent high and low temperature resistance, can work long-term in the range of-50 to 200 DEG C, and has excellent weather resistance, can also maintain good condition for more than 20 years in outdoor environment, and is not easy to yellow), the shell 1 is made of 6061 aluminum alloy.

[0036] In the embodiment of the application, the LED wall washing lamp applied to underwater adopts long strip H-shaped 6061 aluminum alloy shell 1, combined with the end cover assembly 2 sealed and covered at both ends and the tempered glass cover plate 3 sealed at the top, to build a solid and waterproof structure, to ensure the safety and stable operation of the internal LED photoelectric module 4. Among them, the H-shaped shell not only provides excellent mechanical strength, but also optimizes the resistance performance in water flow; and the selection of 6061 aluminum alloy is particularly suitable for underwater environment due to its good corrosion resistance and easy processability. The first cavity 11 is used to accommodate the LED photoelectric module 4, and the complete isolation from the outside is realized by pouring silicone AB glue, this sealing method not only can effectively resist water pressure, but also can prevent water and other impurities from invading, to ensure the reliability and safety of the lamp working in water for a long time.

[0037] As prior art, the LED photoelectric module 4 is composed of key components such as LED chips, substrates (metal core printed circuit boards MCPCB or ceramic substrates), driving power supplies, optical elements (lenses or reflective cups), and thermal management systems (heat sinks and thermal paste), which work together to ensure high-efficiency light output, stable performance, and long service life. In one example, high-brightness LED chips of the CREE XP-G3 model can be used, which are known for their excellent luminous efficiency and color consistency; for the substrate, a whole circuit board made of 6061 aluminum alloy can be selected, which not only provides good heat dissipation performance, but also is easy to process and shape. In addition, in order to achieve precise light control, customized optical lenses can be used to optimize the beam angle and distribution, while high-efficiency drivers are used to ensure stable current supply.

[0038] Further, Figure 3 The end cover assembly of the underwater LED wall washing lamp is shown in the structure schematic diagram provided by an exemplary embodiment of the utility model, and the first cavity 11 and the end cover assembly 2 have a glue blocking pad 6.

[0039] In the embodiment of the present application, the glue blocking pad 6 arranged between the first cavity 11 and the end cover assembly 2 plays a crucial sealing and buffering role. The glue blocking pad 6 effectively prevents the sealant 5 that may overflow during installation from entering unnecessary areas, ensuring that the sealant 5 only fills the space around the LED photoelectric module 4, thereby maintaining good sealing effect and preventing moisture and other impurities from entering the lamp interior. At the same time, the glue blocking pad 6 can also absorb certain mechanical vibrations and impacts, protecting the internal electronic components from external environmental influences and enhancing the stability and durability of the entire lamp structure. In addition, it also helps to compensate for the gap caused by manufacturing tolerances or assembly errors, further improving the overall waterproof performance and reliability of the underwater LED wall washing lamp.

[0040] Further, Figure 4 The inside structure schematic diagram of the end cover assembly of the underwater LED wall washing lamp is shown, Figure 5 The outside structure schematic diagram of the end cover assembly of the underwater LED wall washing lamp is shown, the end cover assembly 2 includes: an end cover 21, the inside of which is sealed and covered on the side edge of the first cavity 11 through a silica gel pad 22, the end cover 21 also has an airtight hole 23, an external negative pressure tester seals the first cavity 11 after vacuumizing through the airtight hole 23 and uses an airtight screw 24, and the end cover 21 is installed on the shell 1 through a bolt.

[0041] In the embodiment of the present application, the end cover assembly 2 comprises an end cover 21, a silica gel pad 22 on the inner side, and an air-tight hole 23 on the end cover 21, which collectively ensure the high sealing between the first cavity 11 and the external environment. Specifically, after the external negative pressure tester performs vacuumization on the first cavity 11 through the air-tight hole 23 and is sealed by using an air-tight screw 24, and the end cover 21 is fixed on the shell 1 by using a bolt, the silica gel pad 22 is tightly attached to the side of the first cavity 11, which effectively prevents moisture, dust and other pollutants from entering the inside of the lamp, and guarantees the safe operation and long service life of the LED photoelectric module 4. In addition, this design can also withstand the pressure changes under water, maintain the stability of the internal air pressure, and ensure that the lamp can maintain excellent performance and reliability even in complex underwater environments

[0042] As a supplementary description, the bottom of the second cavity 12 is connected with a mounting bracket 7, which is hinged with the bottom of the second cavity 12, facilitating the installation and adjustment of the irradiation angle of the LED wall washing lamp applied under water.

[0043] In addition, the LED photoelectric module 4 is connected with the external power supply through a power plug 8.

An external negative pressure tester performs vacuumization on the first cavity through the air-tight hole, and is then sealed by using an air-tight screw, and is installed in cooperation with a rubber pad, thereby realizing double sealing, dustproofing and waterproofing, and protecting the internal elements. The mounting bracket at the bottom allows the irradiation angle to be adjusted, and the pressure-resistant metal threaded waterproof plug ensures the safety and reliability of the power connection. The overall design optimizes the mechanical strength, water flow resistance performance and long-term working reliability in the underwater environment.
