Features of light catching

Among insects, I am interested in grasshoppers, beetles and cicadas. Butterflies - only for the sake of view 100%.

The situation with cicadas in the tropics is remarkable. Cicadas in the mass "turn on" as soon as it begins to get dark and for several hours you can clearly observe the "change of soloists": as dusk thickens, some groups fall silent, but others are replaced. In my opinion, this happens very quickly, because in the tropics twilight is not very long. Unfortunately, I do not know any works on this topic, although it is very interesting!

The situation is similar with straight-winged birds, with different groups active at different times. This also applies to summer in the light.

It should be the same with beetles and butterflies, but I'm not an expert here.

Roma, I see oddities, about them and food, people from the "culture" such questions may not come to mind, only when they collect them will be fucked longer.
The diagram doesn't match the drawing, and that's what I wrote about.

In the picture, you can see that the lamp that was shining has one of the condee's legs hanging in the air. Although the photo is small and I can't see more precisely.
A small drawback of your scheme may be that when turned on through the same Chinese dc-dc converter, the protection will be triggered and the lamp will turn off. In the finished epra, smooth ignition and no jumps, i.e. a large lamp can be set on fire.

I just don't have time to dig around and deal with the theory, it's much easier when someone who knows will tell me.
You can buy dc-ac, but not at a power of 10-20 W, and it is already problematic to cram 100-200 W into the lamp, so DIY makes sense.
I once drowned the camera in the sea, then took it apart, washed it and dried it. And in the process, I was pushed. The camera did not come to life, I bought a new one, with the ability to dive up to 5m and shockproof 1.5 m.

I was shopping here today and saw this one led lamp.
It is expensive, but it takes 12 W and shines like a 100 W incandescent lamp. Compared to the 20W housekeeper, it will consume less battery power! Just need to find the converter circuit...

The converter circuit discussed here?
http://alled.ru/3hpd-1-high-power-white-led.html
I will probably take something like this to start with,the lumen/W ratio is suitable, and 12 W turns out to be twice as many lumens.
Make it so, for example, that part of the light shines on the screen and part in space.

First, why do you need a directional light? I recently wrote here about 360 degrees.
Secondly, why do you need this quick-drying stove? We have already bought similar lamps for spotlights in some offices, the lamps quickly dimmed, some burned out.
Third, why do you need 220V? You can buy LED and driver for 13 bucks. and connect directly to 12V.

The savings bank and the SD driver do not care what to eat, but you need to take into account the conversion of 12-220-12 eats energy, the cooler on the converter eats energy.

Another plus savings and lumens - they do not care about heating, but the LEDs in the lamp, with the body heated to a temperature that you can not touch, exist on the verge of death. This is a huge disadvantage of LED lights and there are already people who have thrown out hundreds of trs for SD lighting in workshops and got rid of dead lamps. Not for nothing, of course, some sued the supplier, who gave a 5-year warranty. As a result, the haze is now shining there.

As for the lamp, I agree, it is not worth it
, for example, you can make a chain of any LEDs closed in a ring . With any number of them and any ring diameter. Just 360 degrees and will be.

How many lumens does this 10 padded jacket give out? Simply, climbing on sites with LEDs, I came across the fact that the less powerful ratio of lumens to watts is higher.

The converter circuit discussed here?

No, that scheme is for saving lamps. Here a slightly different version is needed.

I'm currently going through all the possible light sources and choosing the best ones.
160 gr. is not so small, especially if the lamp is located at the bottom of the screen.
I don't know about the fact that they die quickly, but thank you for the information.
And I haven't dealt with ebay yet. Of course, this is an interesting thing. Is 20000K a color temperature?

Well, I also initially wanted to put sd cri cml u2. But the toad. This terrible creature strangled me and I refused in favor of a Chinese product with 1000 lm against 1200 or so. It is clear that I will get less from the Chinese, and in the end I will lose about a third of the flow.
Feeds are about nothing at all. I somewhere on another forum considered how much they give in reality, it turned out terrible numbers. Plus, half-dried tapes in stores talk about their work.
What is the difference between a startup savings account and a driver? They don't need a sinus. So they will work.
20000K is just white light. Don't pay too much attention, you can find it with a smaller number, I gave the first link that came across.
I'm even a little against sd in fishing because of the complexity-the need for a radiator and cooler.
And without them, the use does not make sense..

I didn't say anything about the tapes,on the link I have a powerful single-source with 220 lumens at a current of 700 mA.
I meant to make kolcho on an aluminum basis from similar LEDs.

Everyone was smarter in this case than BadDen, buying a savings bank(s) for 12B.

save money? I do not think that it will be brighter than such diodes.

I was shopping here today and saw this one led lamp.

This lamp is not very suitable. The reasons have already been mentioned above.

I'm currently going through all the possible light sources and choosing the best ones.

IMHO, acceptable use cases for diodes are:
- diode tape wound on a cylindrical frame.
- factory 12-volt diode lamp with non-directional light.
- diodes arranged in a circle + driver.

alex017, wait a minute. You wrote that you put an LED on 50 watts. And it should give 4500-5600 Lm.

But okoem still caught on to them. And the butterflies flew large, as I look. It seems that there he has a bear somehow sitting (Kaya?), a few peacock eyes.

And in general, I and such a diode like.

And the butterflies flew large, as I look. It seems that there he has a bear somehow sitting (Kaya?), a few peacock eyes.

Bears-Arctia villica (in that photo there are 3 of them). There are no peacock eyes, but there are moths of Hypomecis roboraria.

No, that scheme is for saving lamps. Here a slightly different version is needed.

Such a converter, therefore any of the sold 12/220, is also suitable for this lamp, but why? ...

No, what 50W battery-powered diode?! I'm not crazy yet quite that))))
It seems that someone from the 55ACH accumulator was going to light up and take it with them by car, to fish the surrounding area.
With the approval of BadDen, I bought a 10W Chinese diode for 1000lm, as I spared the money for krishki, I was rushing around, not knowing what to do
No one wants to fool around with a decent design with diodes, but just like that, nothing good will come of them. This is still a new, undeveloped and wayward technique.

Diodes should give 100lm / w! Less is garbage! From here, 20W should give 2000-2100lm! I have an aquarium of 2100lm.

And now, after I despaired almost in the extraction of batteries, I think that I will have to catch only on a UV lamp!

I screwed a 9W power bank into the night light. It turned out not to be a night light, but you can read in the room with good eyesight. These are the" bad " savings accounts.

Yes, Roma, any 12/220 will do, but the main question is "why". I have it on my desk, I think nafig it is bought...

and the UV-trubk4a from you that also works from 12v?

And the butterflies were flying.

Here's another animal, more interesting - http://molbiol.ru/forums/index.php?showtop...dpost&p=1383328

and the UV-trubk4a from you that also works from 12v?

tiger33, no uv tube directly from 12V works.

Yes, this pipe works directly from 12V))
I have an 18W UV compact, it works from the factory-made 12V epr with smooth ignition and current limitation depending on the lamp power up to 40W inclusive.

By the way, about the feed I linked to yesterday.
The "economy" feed differs from the "premium" one not only by the number of working hours. I'm glad I noticed.
SMD 5050"economy "

By the way, about the feed I linked to yesterday.

Thanks! It is necessary to consider for the future.
I took the one I found. Neither "economy" nor "premium" is written on it.

And some LEDs are capable of giving 160lm / w (or 160lm/LED) at a certain current (minuscule)..... Think about it....

Today I bought 20pcs NiMH accumulators for 3Ah and a box for 10 pcs.

Thanks! It is necessary to consider for the future.
I took the one I found. Neither "economy" nor "premium" is written on it.

The main thing here is to look at the characteristics.
By the way, on the same site, it turns out, there is an article: How to choose an LED strip

And some LEDs are capable of giving 160lm / w (or 160lm/LED) at a certain current (minuscule)..... Think about it....

Can you give us a link to such LEDs? And then I don't find something on ebay...

So far, lithium batteries have only one advantage over lead ones: they are lighter. And in terms of reliability, they lose in 99% of cases. If it were otherwise, lithium batteries would have long been used everywhere, including motor vehicles. If you go to catch insects: then you need to catch, not mu...go with the bait. Lead pipes are heavier and bulkier, but they are practically trouble-free. I'll leave the first place to them for now.

Lead-acid batteries are not allowed to be carried in the plane's luggage. With a certain amount of bad luck, they can be withdrawn.

I'm not going to fly anywhere, fishing will most likely be only in the region and if you are lucky in the adjacent ones.

Wave Storm, above I gave a link LED for 1W gives 220 lumens.

How is it single-roll at 220, it says :

Luminous flux-130 Lumens at a current of 350 mA, 220-230 Lumens at a current of 700 mA *. The power supply voltage is 2.9-3.5 volts. Maximum operating current: - 700 mA.

So one watt is only at 130L, and at 220L-2.5 W.

However, even if 2.5 W, it will be more powerful... I'm really confused.

I think this is all a discussion lizh would talk))) If you catch-bags to stack, then only DRLka and analogs, and about diodes-200L, 500l, or 1000l-there will be no special difference! Anyway, this is a one-night stand, just for the sake of curiosity, so the usual lantern will suffice

I'm not going to fly anywhere, fishing will most likely be only in the region and if you are lucky in the adjacent ones.

What are the problems in your field?
The simplest options, there are 2 of them, IMHO:generator (as far as finances and load capacity allow) + any lamp (DRL, DRV, etc., etc.);a set of 1-2 12V batteries, a charger for them, and 1-2 lamps (1 UV, the second ordinary LDS) - the weight is less.On last year's trip to the Crimea, I took with me a set of batteries, a charger for it, and a pair of tube lamps bought in Entosfinks. At Sheremetyevo airport, during the baggage check-in, Sabov residents had questions: "But this battery you have, what is it? Oh, lithium-ion, all right, then."

Diodes with a recoil of 160lm / w at low currents

What does this have to do with problems in your field?

He writes about the fact that fishing in his area is much easier to equip. And the most difficult thing to equip is the power source.

So I also grow that I will use 12 V lead batteries. In the area of that just no problems. I said about airplanes that there will be no flights and therefore lead ones will roll.
And I went to the Crimea by train)

You are the main thing, measure the current and calculate the working time for crafts, so that it does not happen that you came to catch, turned on the light bulb, and it went out in an hour.

yes, this is understandable.

I said about airplanes that there will be no flights and therefore lead ones will roll.

No need to swear

I like this toy 12V 5Ah.

With an enviable, long-term consistency, from one to three specimens arrive exclusively
in the last half hour before dawn.
As an exception, I remember one fishing trip when I fell asleep and the maculosa was flying
en masse. More than 20 copies. I don't know the time of summer, Djon or Shustov will tell you.

After 2, but, there was an abnormally cold night, 4-6 degrees C. At more than 30 in the afternoon, this is in August, in the south of Ukraine.
Indeed, Chelis maculosa is a harbinger of dawn.
