Problems solved by technology

[0003] A single sealing ring is not enough to resist the water pressure in deep water, and the sealing clamp structure also has the disadvantages of poor waterproof effect and poor waterproof performance for underwater operations. Although the use of sealant bonding can obtain better waterproof performance, and the use of sealant bonding Finally, the maintenance of lighting fixtures is inconvenient. After forcibly disassembling the lighting fixtures for maintenance, its waterproof structure will be destroyed.

Abstract

The invention relates to an illumination lamp, which comprises a shell body. The shell body is formed by buckling an upper shell and a lower shell; a light source is arranged in the shell body; an inner layer sealing ring is arranged between contact surfaces of the upper shell and the lower shell; the periphery of the inner layer sealing ring is provided with an outer layer sealing ring; a gap isreserved between the inner layer sealing ring and the outer layer sealing ring; and the water pressure resistance of the inner layer sealing ring is higher than that of the outer layer sealing ring. A structure of two layers of sealing rings is adopted, so the water pressure resistance of the entire lamp shell is equivalent to the sum of the water pressure resistance of the inner layer sealing ring and the water pressure resistance of the outer layer sealing ring and the submerging depth of the illumination lamp is further increased. Internal components of the illumination lamp are convenientto maintain and the water-proof performance of the illumination lamp during deep water operation is improved.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a deep-water lamp with high-efficiency waterproof effect. Background technique [0002] Generally, lighting fixtures used for underwater operations must adopt a waterproof structure so that they have a certain waterproof level and are convenient for underwater operations. The lighting fixtures for underwater work in the prior art usually only use a single sealing ring, or adopt a sealing clamping structure, or adopt a sealing glue bonding method. [0003] A single sealing ring is not enough to resist the water pressure in deep water, and the sealing clamp structure also has the disadvantages of poor waterproof effect and poor waterproof performance for underwater operations. Although the use of sealant bonding can obtain better waterproof performance, and the use of sealant bonding Finally, the maintenance of lighting fixtures is inconvenient. After forcibly disassembling the ...
