Description

A kind of latent device underwater lighting fixture

Technical field

The utility model belongs to field of machining, and in particular to the lighting apparatus neck that marine settings underwater hiding-machine uses Domain is more particularly to a kind of latent device underwater lighting fixture.

Background technology

Underwater lighting fixture is for the illuminator of underwater view, decoration, operation illumination or underwater photograph technical video display.Divide anti- Immersion and anti-two kinds of diving.The former is for shallow water operations areas such as fountain, swimming pools；The latter is used to provide the operation area of the depth of water.

Most of protected against the effects of immersion currently used in the market and anti-diving illuminating lamp tool are LED lamp, and underwater range is short, bright Degree is poor, and is chiefly used in 50 meters with headwater depth, and can reach 100 meters of depth individually, but selling at exorbitant prices is unsuitable for public use.It is existing The glass that technology Under water lamp uses, it is impossible to deep water working environment is adapted to, easy permeable electric leakage, and glass and lamp body be not pressure-resistant, Poorly sealed, brightness is inadequate, is not reached requirement using the depth of water, and hermetic unit is mostly using asbestos cord sealing and fitted seal glue Sealing, sealing performance is bad, extremely be easy to cause the generation of water leak accident.

Due to limitation of the prior art to leakproofness, luminous range and pressure-resistant degree, underwater hiding-machine is seriously constrained, especially It is that underwater sightseeing is dived the development of device, this just proposes active demand to the promotion of underwater hiding-machine illuminator overall performance.

Utility model content

The utility model provides the latent device underwater lighting fixture that a kind of overall performance is promoted, and the use of the equipment can carry The latent device of height increases fitting glass pressure resistance degree, and increase substantially water resistance using depth.

To achieve the above object, the utility model provides following technical solution：A kind of latent device underwater lighting fixture, including pressure Lid, glass, lamp cap, lamp housing and sealing device composition, the glass are fixed by lamp housing and gland, and using extraordinary Glass is manufactured；The lamp cap is installed on using xenon lamp inside the lamp housing being welded by finished product pipe fitting；The sealing Device carries out pressurization in lamp housing end by pressure-resistant seal material, and lamp housing and latent device are connected across power cord.

By xenon lamp instead of common LED light, lamp brightness higher, light propagation distance is farther, extends underwater sight The visual range of light.

Preferably, the glass uses high-temperature and high-presure resistent special glass, and can adjust glass according to specific resistance to pressure request Glass thickness.

By the selection of high-temperature and high-presure resistent special glass, the pressure-resistant degree of lamps and lanterns can be increased substantially, is improved latent The depth of device underwater operation, and reduce the generation of lamps and lanterns water leak accident.

Preferably, the high-temperature and high-presure resistent special glass uses quartz glass.

Preferably, the pressure-resistant seal material is tetrafluoro packing, and water-swellable realizes sealing effect.

Pressurization is carried out by filling pressure-resistant seal material, the sealing material after sealing in lamps and lanterns expands after meeting water, into One step plays sealing effect.

Compared with prior art, the beneficial effects of the utility model are：Latent device lamp is increased by the use of special glass The pressure-resistant degree of tool so that headlamp meets the requirement of 200 meters of depth of water；Lamp cap uses xenon lamp instead, enhances brightness, and Light propagation performance is more preferable；Lamp housing is formed using pipe fitting welding, has not only been met resistance to pressure request but also has been reduced cost；In order to solve Power cord sealing problem, the utility model specially devise a kind of sealing device, this device is filled with pressure-resistant material, is met after compression Water expands, better tightness.The invention can ensure that headlamp uses in deep water for a long time without damage, water-tight, Er Qietou Luminosity is good, beautiful and generous.
