What do you mean by monochromatic light

monochromatic lighting is dangerous

  • does that scare you? after all, you know that everything will soon be replaced by LEDs! 0

    1. about as much as climate protection * not a few mine days * (0) 0%

    ... heyaa out there,
    I discovered something on my travels through the internet that worries me.
    It is pointed out that we cannot simply replace the biological glow with other light sources * fluorescence, discharge, LED *, because this also results in a hormonal change in the body!

    plea for healthy light sources * PDF *

    interesting things:
    a blue 3W powerLED generates just as much light as a 100W lightbulb with a blue color filter
    cold white LEDs have a negative effect on our hormone balance

    what do you think of it and what kind of solutions are there ?! after all, we spend about half our life under artificial light !!

    the effects of spectrum deprivation were found on american submarines, which is why the three-band * daylight * FL tubes were created !!

  • may well be, but that's why I'm not afraid and now avoid every LED [- (

    Humans are creatures of habit and if need be, they also adapt to the LED: -k

  • Although I find it contradicting that one takes sunlight as a reference and then at the same time thinks a lot of blue light is harmful.
    So sunshine should also have a negative effect on our hormone balance because it contains a lot of blue and violet light !?
    But that is illogical because, as I said, sunlight is rightly used as a reference.

    Second: 10% efficiency comes with good halogen lamps, but 10% of the total radiation.
    An incandescent lamp emits around 75% of the power consumed as radiation and 10% of this is only 7.5% of the total power, a large part of which is in the deep red to which the eye is not sensitive.
    Overall, you still come across a catastrophically poor degree of efficiency or here a light output of max ~ 26lm / W.
    However, 90% of incandescent lamps are far below this, and most halogen lamps do not achieve this value either.

    Third: A wrong spectrum can certainly have negative effects on the body, but the total amount of light that is absorbed and the spectrum is made up of the indirectly reflected radiation, which then also has a completely different spectrum than the radiation from the light source himself comes.

  • solution approaches:

    full spectrum fluorescent tubes have 4 phosphors and 4 gases and thus generate a complete spectrum.

    Transferred to leds this means: you need leds with several chips in different colors and several phosphors inside to achieve full spectrum (from ir to uv-a)

    the flicker can be avoided with pufferelkos.

    everything solvable. By means of illuminants in which EVERY type of LED that is feasible is plugged, you can create any color and specular gradients, i.e. an extended color system, instead of rgb quasi rggbvyiuopht ...

    this may reduce the efficiency again something, but should still be above today's ESLS

    Otherwise I think: we are surrounded by fluorescent tubes in offices, outside by street lamps, etc. As long as we regularly go for a walk in the daylight, let light through the window during the day, instead of sitting in the "bunker" under the kusnti light and sleeping completely, nothing worse is to be feared.

    The problems arise ABOVE ALL with people who spend the whole working day in artificial light and get little daylight: Wall:

    and especially in the bedroom. every weak source of light, even the light from control lights can, under certain circumstances. disturb your sleep

    Now we finally know why the FBI, CIA and the other secret services, which are known to hardly get daylight for security reasons, keep building muck And why mining is so inefficient Does anyone happen to know a subway guide?

  • Incandescent light has a neutral effect on that
    Endocrine system because there is very little short-wave
    Contains radiation, i.e. blue, indigo and violet.

    Quote from "John.S"


    a large part is in the deep red to which the eye is not sensitive

    not the eye, but our skin!
    Color therapies are usually applied over a large area, i.e. on the naked body! Lichtbaeder are widespread in the bathtub.


    This is how the earth receives high frequencies
    Light radiation from the sun that from the
    biological systems and in
    converted to low-frequency thermal radiation and
    is released again


    ... that means that blue light is converted into infrared radiation !? thus the * evil * blue component is converted into qualitatively higher heat radiation, so there is more or less excess.

    Does reflected radiation change the wave length or is it just fooling the eye? is it just split up * gradient * ?!

    I'm really not an advocate of LEDs, you know me, that's why I would have loved to work on solutions. We all know that the LED will prevail as a source of lighting, although the OLED should not be neglected either, but we have the same problem ...

  • ... chch, post's are accumulating there !! = D>

    in the mining industry do you use incandescent lamps * headlights * !? that will be another problem ...: lol:

    ... and then comes the winter of 2012, we work under warm white * sunnywhite * LED light, the street lights emit cold white light because of their efficiency, in the subway there are LEDs, the car interior light ne LED. the days have 7 hours of sunshine * january *, which we working people only notice through triple-glazed * IR / UV barrier * windows, it's cold we dress warmly * covered with our whole bodies * ...

    Medical studies have found that the light from conventional fluorescent tubes has the same effect on people as stimulants and sleeping pills taken at the same time. The bright white artificial light causes a steep increase in stress hormones and, on the other hand, confuses the pineal gland and thus the production of melatonin, but also the most important cell protection of the body. The person is plunged into a constant rollercoaster of nervousness, aggressiveness and tiredness, a constant stress that makes people sick

  • All in all: all light is harmful, except sunlight, which is great, if the UV exposure is too high, then that is also harmful ...

  • That's not true either, it depends, as everywhere, on the right amount whether full spectrum lights "daylight lights" are the solution? During the day the sun shines, in the evening we use artificial light. Fridays, 11 p.m., in front of the TV, a halogen lamp on in the background ...

    Does anyone REALLY want light like 12 noon? nope, because it's evening, midday is uml, you sit in front of the tv and will go to sleep in 1-2 hours, the dimmed backlight is appropriate here, with led you would have to take luxeon, soul or cree in warm white.

    the sunlight also has a variable spectrum depending on the time of day. midday sun, evening sun, etc.

    the artificial light allows us to be more or less independent of the time of day, but on the one hand you shouldn't forget that you have to take care of a regular daily routine yourself, of course, you can go pen at 6 a.m. and get up at 4 p.m. to recommend sises rather less ...: -%

    and in winter, when there is little sun in our latitudes, such a daylight luminaire can certainly do no harm , I think that it will bring ewatt

    however, NCIHT replaces the experiences of cycling with the summer landscape, walking in the woods, going for a swim, etc. And above all: you can pack vitamie in tablets, you can cycle on the Heimträner, you can have music players, cameras, games consoles, e-books and much more in a single mobile phone, but it just doesn't replace "the real think": wink:

  • ... for the * some * vitamins to work, they also need a quasi photosynthesis, vitamin D for example;

    With the help of UV rays from sunlight, the body produces the hormone "vitamin D" in the upper layers of the skin. Its name is misleading because the body cannot produce "real" vitamins itself; they have to be taken in with food, but sunlight converts cholesterol into vitamin D. If there is no sunlight, no more vitamin D can be found in the body after only 5 weeks and bone loss and further disturbances in the calcium balance occur.

    Hmm yes but it only increases the blood circulation in the skin through the heat.
    Especially the incandescent lamps, no matter how much infrared they emit as a percentage, after 1-2m the radiation strength is already so weak that there is no measurable warming of the skin.

    ... that means that blue light is converted into infrared radiation !? thus the * evil * blue component is converted into qualitatively higher heat radiation, so there is more or less excess.

    This means that the radiation is absorbed and then given off again as heat radiation. Nevertheless, the sunlight has an extremely high amount of blue, indigo and violet and everyone who lingers outside gets the "full charge of it"

  • LEDs are praised in the article. at least to a certain extent. the main thing is that the energy-saving lamp is "bad".
    But with the uncomfortable light of the energy-saving lamp, I can only say
    my shelf is completely illuminated with energy-saving lamps. and that is very warm light. there are also "warm" energy parlams.

  • These energy-saving lamps don't even save that much energy, they require a lot more energy in production and disposal. If the light is not optimal now, then Australia would have waited better for the LED ...

  • ... my talk, madman! * gruezi, by the way! *

    @spyro
    read the part through again, it is not about the feeling * cold / warm white * but about the spectrum that our skin absorbs and is required in our body!

    John
    Not only the heat radiation is decisive, also parts of the * invisible * noticeable * light, as well as the UV spectrum penetrate into our body and convert * know'javonderphotosynthesis * into vital substances.

    We already get the full charge, but thanks to the conversion into heat, the red component increases again ...

  • So let's just briefly say I'm a lighting technician and maybe at least I can say something about it. First, artificial light is generally harmful to the body. After all, there is no UVA and UVB radiation. However, it is quite possible for the eye and the well-being to cope with the artificial light and its color spectra. However, the artificial light should be as close as possible to daylight (regardless of whether it is LED or halogen). The spectrum is important. And monochromatic light or monochromatic light is definitely not healthy for the body in the long term. But since we usually (should) spend our free time outside as well as possible, that won't kill us. And if necessary, you can also go to the door to tinker with LEDs! or?
