Roselectronics has developed a deep-sea light device

The engineers of the Ruselectronics holding of Rostec State Corporation have developed a lighting device designed for deep-water work, the design of the device withstands water pressure at a depth of up to 300 meters, reports press office companies specifically for "Military Review"

The luminaire, which received the designation "TS-12", was developed at the St. Petersburg Research and Development Institute of Television, JSC in order to ensure the operation of television underwater systems. At the same time, the device can be used on submarines and self-propelled vehicles, as well as to illuminate the working area of ​​divers.

The working body of the device consists of seven clusters of seven LEDs of type XLD in each. The spectral composition consists of white light, if necessary, can be changed, for example, to blue-green, or blue light. The illumination range at 70 W power is 2 500 lux per 1 meter in the air. Supply voltage - 24 V, current consumption - 2,5 A.

The angle of illumination generated by the device is 40 degrees. At the same time, it is possible to install secondary optics, which allows to reduce the angle to 30 degrees in order to increase the range of illumination. The weight of the lamp - 2,8 kg, with the use of secondary optics - 3,3 kg.

The case diameter is 170 mm, the diameter of the glass in the case is 150 mm. Glass thickness - 15 mm.

As previously reported, the holding Roselektronika produces a number of light semiconductor devices for the needs fleet. In particular, the Tomsk Scientific Research Institute of Semiconductor Devices has developed an LED module for the SS328E marine lamp for two power options - 220 V and 30-40 V. In addition, Moscow Optron JSC has developed a prototype lighting system based on the use of laser radiation and a remote phosphor . The development eliminates the danger of a fire or explosion due to a spark when the power is turned on and is able to work in aggressive environments, as well as under water.

The devices will be presented at the VIII International Naval Salon, which will be held in St. Petersburg from 28 June to 2 July. The integrated exhibition of electronics electronics - pavilion 7, stand 701.

They made you laugh, you lower the LED at least a kilometer into the water. As it burned, it will burn. Apparently they decided to cover the theft of money.

[siberalt]

What will the divers say? Maybe they have gotten better for a long time?

At a depth of 300 meters, divers appear maximum in the form of drowned, apparently.

[krot]

This invention was not fiction to me alone! In the Mariinsky Depression there is generally nothing to be done by such specialists for another hundred years, probably))) Loafers!

[krot]

There is no peace .. excuse me! Give me a few million and make equipment that will illuminate at a depth of 1 km! )))

[Black Colonel]

In the Mariinsky Depression ...
Actually in Mariana.

[Lycan]

In MaryVannes .....

[Stas Snezhin]

The next nanotechnology holding: LED epoxy fill ..

[_Ugene_]

And will your LED be powered from cosmic energy or should it glow without power? Or do you offer live wires, lenses, etc. so lower it under water, and even the pressure at this depth is 30 times more than atmospheric.

[Niccola Mack]

so lower it under water, and even the pressure at this depth is 30 times more than atmospheric.

Even in Soviet times, such a cable KTSHE (cable for electric drilling) was produced - so it had a maximum compressive force of 122 MPa. Let me remind you that normal atmospheric pressure is 101 kPa. So all these "innovative developments" are cheap advertising !!!

[_Ugene_]

According to your searchlight, this is one LED + electric. cable?

[meGrail]

Advertising may be cheap, but denyuzhki state sooo good go

Yes ... yes ... Heard already ...
You are one of those who suggest changing the government, although it has already been changed 12 times ... You want a new president, but you don’t know which one ...
You just whine how you feel bad ...

Have you omitted already?
And “burn” is cool you said. Feels like a "responsible specialist." (firewood burning)

Eh ........
In the article, is it written that they made a deep-sea LED?
Which, by the way, stupidly closes in the water and he dies
It's about the device, or a deep-sea LED spotlight, and this complicates everything. Pressure on 300 m 30 kg per cm square .. now take a network LED table lamp and try to make it work in water at this pressure .....
Good luck!
Although there is nothing new there, it took, did

[meGrail]

Since they began to literally, according to GOST 16703-79 - “Lamp - A light device that redistributes the light of a lamp (lamps) inside large solid angles and provides an angular concentration of light flux with a gain no more 30 for round symmetric and no more 15 for symmetrical appliances "
A "Spotlight - A light device that redistributes the light of a lamp (s) inside small solid angles and provides an angular concentration of light flux with a gain more 30 for round symmetric and more 15 for symmetrical appliances. "
Do you have the specification of the device in your hands, since you confirm that it is a spotlight, not a lamp, as it is written in the article?

And it’s already a no brainer that an LED can be filled with the same compound, and it won’t close anything.
And an LED, if you, of course, know its design, has a monolithic construction without cavities, so that it has pressure, up to certain and very large values, as if without a difference.

[bk316]

And it’s already a no brainer that an LED can be filled with the same compound, and it won’t close anything.

And the hedgehog understands why no one floods, for example, in the same tourist or scuba diving lights diodes compound?
Well, let's bookworm, anyone can copy-paste, but just a little thought ....

[meGrail]

Yes, even paraffin findings pour! Who cares? Is it really in your view to isolate the conclusions of the diode - is it directly cosmic complexity ???

[Mountain shooter]

The LED is just not afraid of any pressure, but the batteries and the power circuit? Sea water is an excellent conductor ...

[Lycan]

Maybe it's not a diode (which is probably "long-range"), but the overall design of the device.

This is not in every store you will find.

[meGrail]

What is the "heat balance" for a device with a power of some 70 watts, and even at such a depth ?? And if you take into account that conventional LEDs without any tolerances have a permissible temperature of -60 +80!

[Lycan]

Oh, 70 watts is just the beginning. For underwater construction, more power will be needed, which means that it will be necessary to competently organize cooling. This is where the beginning is laid. You remember that the processors in home PCs were once just a big mikruha too, without any “perversions” from above. Now, the cooling factor is almost the whole art of using yourself know what inventions and tricks.

[meGrail]

Ohohoh, I recall the "soldered" youth and calculations of cooling radiators for transistors. I remember it turned out that with active cooling, a 200-watt ribbed radiator with 20 * 20 cm was enough for any XNUMX-watt amp ...
But in ordinary computers, with a “boxed” cooler, they are not the same already, a big cube of 20 * 20 * 20 cm. And for a long time there has been a crystal-substrate contact problem in the processors, which is why there are all kinds of “dark flint” concepts, and as for everything the rest, here Uncle Lee is doing a great job making whatever radiators you want. And it doesn’t smell of any “space” technologies.
And if you take into account the thermal conductivity of water, and even taking into account the configuration ... Actually, cooling here is not a problem at all, you should not compose.

[Lycan]

1) A cart with a horse-drawn drive thousands of years ago could also be left "as is", but for some reason steam / fuel / electricity / + running gear on bearings + wheels on airbags - for a wonderful reason, they became more popular in large settlements.
2) Uncle Lee has nothing to feed. Relations are partnerships, but if you do not feed our engineers, then you will have to wait for innovations exclusively from abroad and only when they are released into a wide market.
3) As for the “space technologies”: if you relate to the development of “cosmo-technologies it doesn’t smell, you don’t really need to, what to steam, and so it works” - what to do with the craving for experiments, curiosity, convinced enthusiasts (like S. Korolev, R. Branson, S. Jobs, Kulibin, Da Vinci) where to come from ???
4) "water with confection" is not the ultimate dream. In addition, there are situations where 1/4 ... 1/3 of the weight (and size) of the apparatus eaten by thermal stabilization is crucial. And the farther into the future, the more clearly this meaning.

[mahoney]

At the bottom of the ocean for 20 years lies a fiber optic cable and is shining well, again the money was stolen.

[JD1979]

Cool. State award to developers. Only now a normal LED on 50W gives out 4500-5000LM, and this is one module, for a set of clusters of 7 diodes. True work on 32-34V. Yes, and the photo could be inserted normal, if you specify the source.

[Zomanus]

Some kind of crap ... Glass 15 mm ... well, suppose. But other?
Yes, ordinary, his mother, an LED matrix.
Maybe just the foundation is stronger than those used in domestic lighting sources.

[meGrail]

Why didn’t you bring all the news? There are some amazing lines:
"In particular, the Tomsk Scientific Research Institute of Semiconductor Devices" has developed an LED module for the SS328E marine lamp for two power options - 220 V and 30-40 V ", we look at the SS328E mega-hi-tech lamp in Google and we find !!
Well, how far did they invent “numb-analog” “nano-device” that they wound themselves with an LED light bulb, and at the nearest store they sell 5 rubles each ??

[water]

Conventional underwater electric lamp in a sealed enclosure. The advantage over existing ones is low energy consumption. Let's see what will be the cost?

[bk316]

Range of illumination at a power of 70 W - 2 lux per 500 meter in the air.

Blah blah about fill with a compound or buy a lamp in the store write (shkolota probably?),
but nobody paid attention to it.
What would that mean?

[bk316]

Range of illumination at a power of 70 W - 2 lux per 500 meter in the air. Supply voltage - 1 V, current consumption - 24 A.

AFFTOR !!! What nonsense is written?
1. The illumination range at a power of 70 W - 2 lux per 500 meter in the air - so the range of illumination is not measured. Maybe the word "distance" is missing after the word "on"?
2. The supply voltage is 24 V, the consumption current is 2,5 A. - And how did you get 70 W?
3. What is the news? Well, they made a lamp from krishny diodes, and actually they did it for such home-made ones. What are the inventions, I will do the same in a dispute (by the way, and really do the same for a boat)
That's probably the unsoldered XLD-AC-007

[meGrail]

Do not beat the author, he just copied the official press release. And in “Roselectronics” itself, I suspect, they simply translated the Chinese datasheet using Google translate.

[tanit]

Why beat the author? To beat is so for commentators.

[tanit]

I will add. For divers, “going to a depth of“ 300 ”is like the whole world’s community — going out into outer space. For money - no less.. And those who leave — two orders of magnitude less (a hundred times if someone is not friends with math) )
