The metal sealed cabin 8 is integrally connected with the first horizontal annular support 31 and the second horizontal annular support 32, which effectively conducts the heat of the lighting device and the ultraviolet device into the seawater, and improves the heat dissipation efficiency.

The lamp bead 6 is put into the slot 19 of the sealed cabin, and the lamp bead is fixed by pressing the bolt 5; the ultraviolet lamp bead 7 is put into the slot 21 and fixed with special glue, and the axial sealing O-ring 3 is placed in the sealing In the sealing groove 15 of the cabin, the translucent cover 2 is snapped into the upper end of the sealing cabin and pressed on the axial sealing O-ring 3, the locking cover 1 is screwed into the sealing cabin 8 and presses the translucent cover 2, and the seal is sealed. One end of the capsule 8 is sealed. The watertight socket 13 is screwed into the threaded hole 25 of the rear end cover, and it forms a seal with the rear end cover 10 when tightened; A through hole is arranged between the lamp bead slot 21, and the constant current module is connected with the lamp bead 6 and the ultraviolet lamp bead 7 through the electrical connection elements passing through the through hole, such as pins, etc. After the radial sealing O-ring 9 is placed In the sealing groove 22 of the end cover, the rear end cover 10 equipped with the watertight socket 13 and the radial sealing O-ring 9 is inserted into the sealing cabin 8, and the rear end cover locking bolt 11 is fastened, and the other side of the sealing cabin 8 is fastened. One end is sealed to solve the waterproof problem of underwater LED lighting. As shown in Figures 5a and 5b, the reflector 4 is clamped in the first horizontal annular support 31, and the side wall of the sealed cavity restricts the radial movement of the reflector 4; the reflector 4 is pressed by the transparent cover 2, The axial movement of the reflector 4 is restricted. The material of the light-transmitting 2 cover is special quartz glass, which has high strength and high light transmittance; the locking cover 1, the sealing cabin 8, and the rear end cover 10 are made of Hsn70-1, which is corrosion-resistant and easy to use. Processing, high thermal conductivity.

The lighting lamp bead adopts an LED lamp bead array, preferably a high-density integrated lamp bead, with high brightness and strong independence, and the damage of a single bead does not affect the lighting of other lamp beads. The ultraviolet lamp bead is preferably a single lamp bead, with a small volume, an irradiation radiation angle of preferably 70°, an effective radius of 100mm, and can emit ultraviolet rays of a specific range of wavelengths to destroy the molecular structure of DNA or RNA in marine organisms, and achieve anti-aging. effects of biological contamination.

The sealed cabin body is closely attached to the lighting lamp beads, and the sealed cabin body serves as the base of the lighting lamp beads, which not only plays a role of sealing and protection, but also has a heat transfer and cooling effect, and directly connects the lamp to the lamp. The heat generated by the beads is transferred to the water, which solves the problem of heat dissipation during long-term operation of the lamp beads.

In order to ensure the anti-biological adhesion effect of the transparent cover, and at the same time to reduce unnecessary energy consumption, in this embodiment, the number of UV lamp beads and the installation angle of a single UV lamp bead are analyzed and processed to optimize the combination, as shown in Figure 7- 9 shown.

Since the lighting lamp beads generate relatively large heat, in order to reduce the influence of high temperature on the light-transmitting cover, the lighting lamp bead 6 and the light-transmitting cover 2 are kept at a certain distance. Because the heat generated by the single UV lamp bead is relatively small, its influence on the light-transmitting cover can be ignored. At the same time, in order to reduce the occlusion of the ultraviolet light by other components of the underwater lighting lamp, the ultraviolet light bead is arranged near the light-transmitting cover.

The UV lamp beads are arranged on the periphery of the lighting lamp bead, so the UV lamp bead should be tilted towards the lighting lamp bead when installed, so that more ultraviolet light can pass through the light-transmitting cover for protection. After data calculation and modeling analysis, one UV lamp bead can not meet the full coverage of UV light, so the distribution and combination of multiple lamp beads is adopted. In this embodiment, a height adjustment element 33 is arranged inside the ultraviolet lamp bead slot 21 where the ultraviolet lamp bead 7 is placed, and close to one or more sides of the interior of the sealed cabin. The pads that pop up or drop can be set by pressing. The height adjustment element includes a plurality of continuous or discontinuous gears. By adjusting the height gear of the height adjustment element, the angle between the bottom surface of the groove for processing the UV lamp beads and the horizontal plane is controlled, thereby controlling the inclination angle of the UV lamp beads. The ultraviolet lamp bead 7 is placed in the ultraviolet lamp bead slot 21 obliquely, and by adjusting the height position of the height adjustment unit, it can be adapted to equipments that require different lighting ranges. Each ultraviolet lamp bead is connected with two leads, the ultraviolet lamp bead is welded with the two leads by solder, and the other end of the lead is connected to the circuit board through pins.

By selecting the cross-section analysis of the UV lamp beads and the lighting lamp beads, in order to enable the single UV light source to pass through the upper center point of the light-transmitting cover and the single UV light source to illuminate the edge of the inner hole of the locking cover, it is calculated that the installation of the UV lamp beads is suitable. The angle is 19°-24°, and the luminous range of the UV light source at the critical angle is shown in Figures 8a-8b. When the installation angle is 19°, the light source on the right side of the UV lamp bead just passes through the center of the light-transmitting cover; when the installation angle is 24°, the light source on the left side of the UV lamp bead just shines on the edge of the inner hole of the locking cover.

By selecting the cross-section of the upper surface of the light-transmitting cover, in order to make the individual UV light sources complement each other without redundancy, after modeling and analysis, it is finally determined that the number of UV lamp beads is at least 5, the circumference is evenly distributed, the lighting range and The UV emission range is shown in Figure 9.

The technical solution provided by this embodiment, through the cooperation of the ultraviolet light-emitting unit and the lighting light-emitting unit, realizes the pressure resistance and corrosion resistance in an integrated manner, the structure is simple and practical, and the assembly and maintenance are convenient. By setting the inclination angle of the adjustable ultraviolet light-emitting unit, multiple effective ultraviolet light-emitting ranges can be obtained, which can be widely used in underwater lighting equipment with various lighting range requirements. User convenience. By involving an integrated metal sealing cavity-metal lighting unit support-metal ultraviolet unit support, the heat of the lighting device and the ultraviolet device is effectively conducted into the seawater, and the heat dissipation efficiency is improved.
