Talk:Infrared heater

I don't think they should be mixed

I don't think they should be mixed, since infrared heater comprises other type of instruments use in science where wavelength selectivity of the infrared spectrum is concerned and important. —Preceding unsigned comment added by 69.38.66.218 (talk) 13:59, 20 August 2009 (UTC)

Hey what's up I don't think you should mix these up! cump? thanks!

I think that the ranges of those 3 kind of heaters are different from "Infrared" page of this wikipedia. Those sentences should be changed like this;

 - SWIR (Short Wavelength infrared) or NIR (Near infrared): 0.75 um ~ 3 um
 - MWIR (Middle Wavelength infrared) or LWIR (Long Wavelength infrared) : 3 um ~ 15 um
 - FIR (Far infrared) : 15 um ~ 1,000 um

Don't you think this is right? MythEast (talk) 06:37, 30 May 2012 (UTC)

Gas filled Bulbs

In the section "Elements of infrared heaters" second paragraph - about electric bulbs - the sentence "Depending on the filament temperature, a filling of the quartz tube with inert gas (e.g., halogen) may be required to prevent filament degradation" needs to be rewritten. There is at least one problem, and perhaps another.

First, the phrase "inert gas (e.g. halogen)" implies that "halogen" is a particular gas, and that it is an inert gas. Well, the halogens are a group of gasses, and they are the farthest things from inert. If an inert gas is needed, a noble gas would probably be used.

Second, one may read through this muddle and surmise that a halogen bulb is used. This may well be true; I don't know. I must question it, though, due to the other mistake. Is the gas inert, a halogen, or a mixture?

The Confusion on this may result from the halogen lamp article itself. That article explains: "A halogen lamp is an incandescent lamp with a tungsten filament contained within an inert gas and a small amount of a halogen such as iodine or bromine." Someone could read this too quickly, mix some words up, and be confused into thinking that the halogen is the inert gas. "Oh," says the the confused person, "this 'halogen' stuff is an inert gas. I guess the inert gas in an IR heater's bulb might be halogen too." Now I'm not saying that the editor who wrote the problem sentence was confused in this particular way, only that he or she was clearly confused about something, and it could have been this.

Since I don't personally know whether halogen bulbs are used or not, I was not able to rewrite the sentence myself. But that is why I added "citation needed," i.e. to back up the claim that they are. Joe Avins (talk) 22:52, 5 October 2010 (UTC)

I created the article this was no self promotion

I created the article this was no self promotion..:-) I have nothing to do with quartz heaters. A heater is a device, the quartz element is a component different from all other types of elements. This needs to be an individual entry as a component to some electric radiant heaters. They are also used in my toaster, different application. And I am guessing they may see new usage in the future. I agree this needs some more work. And I will submit a better photo later :-).. but please expand. quartz heating element

Also should parabolic infrared heaters be mentioned again they are quite different in operation and design/ Also are very common around the world and do not use a quartz tube Syncmedia (talk) 18:20, 25 November 2010 (UTC)

Infrared stoves

I suggest that in view of recent introduction of Infrared Stoves in the market, more details about some technical information of them are added to this page; particularly comparison with reference to thermal efficiency with other cooking mediums. Pathare Prabhu (talk) 02:16, 22 March 2011 (UTC)

Infrared Heater

In regards to medical benefits

http://www.longevity-and-antiaging-secrets.com/nuwave-oven.html

NuWave oven claims it reduces your fat intake via drippings etc, but it's a far shot - so it's really a weasel word since only advertising (no real authorities) claim the health benefits — Preceding unsigned comment added by 74.108.120.80 (talk) 11:56, 22 December 2011 (UTC)

Heat Lamps, and Health Effects

The section on heat lamps as written states that they are used for animal husbandry as well as heating humans in bathrooms, etc. The section on health effects states that too much exposure can affect eyesight. How much is too much? If they are safe for animal husbandry, are heat lamps safe as space heaters in homes with kittens or puppies that don't know how to obey safety precautions? If so, what kind, specifically? I went to this article for the purpose of researching that question, and found no definitely useful information, or citations. Can anyone help fix this gap?

The statements regarding Health Effects on the eyes are incorrect=

Actinic2020 (talk) 20:50, 5 February 2015 (UTC) The statements regarding Health Effects on the eyes are incorrect and the reference invalid (i.e. it is not authoritative ('ask alice'), nor does it even support the statements). There are two diverging issues here -

First, it is Ultraviolet, not Infrared, light which produces occupational exposure hazards for those using welding & cutting equipment. It is also produced through exposure to tanning beds, etc. Further the type of damage to the eye, when exposed to Ultraviolet light, is not as stated and does not typically effect the iris or the aqueous humor. Rather, corneal burns, retinal scarring, and cataracts can occur. (OSHA, and a host of medical references support this.)

Second, Infrared Light (produced from devices creating infrared heat) when administered in small controlled doses actually prevents eye damage caused by exposure to bright light (sunlight & welding) by inhibiting the Muller cells prior to exposure. (See Krisztina Valter and doctoral researcher Rizalyn Albarracin at The Vision Center, Australian National University - this research was widely reported in 2012.)

History

The History section contains some information on the history and discovery of Infrared light, mainly William Herschel's experiment using a prism and three thermometers to discover IR, however there is no reference / citation to this experiment. Could one be added? — Preceding unsigned comment added by Baharini (talk • contribs) 15:18, 10 May 2015 (UTC)

Ref 11

I found reference 11 was gone, but the web archive holds it at https://web.archive.org/web/20140308034933/http://noblelight.net/resources/pdf_downloads/booklet/booklet.pdf -- I just don't know how to properly insert the reference, since there is another date (unavailable in the web archive) with this article. Please do what would be proper? I will probably see it later, and learn. — Preceding unsigned comment added by 2001:980:93A5:1:EC45:12E2:EE5:7AAF (talk) 17:30, 29 May 2018 (UTC)

Stinky

This article stinks. It needs a complete rewrite and is not even a "Class-C" on my quality scale. I like to saw logs! (talk) 08:41, 24 January 2019 (UTC)

This could be more specific. What's missing from the article? What is excess? Is it comprehensive? Please, tell us more. --Wtshymanski (talk) 18:24, 24 January 2019 (UTC)

Are these numbers backward?

Notice that infrared is below the visible spectrum and that it has a longer wavelength than that spectrum. The farther away from the visible spectrum the IR is, the longer the wavelength. But look at this quote: "Short wave or near infrared for the range from 780 nm to 1.4 μm, these emitters are also named bright because still some visible light is emitted; Medium infrared for the range between 1.4 μm and 3 μm; Far infrared or dark emitters for everything above 3 μm." These numbers are getting smaller, not larger. These are wavelength sizes. Does anyone see that the sizes should be getting larger? MythEast pointed this out 8 yrs ago and it's still not being addressed. Longinus876 (talk) 05:29, 8 January 2020 (UTC)

Not sure what you mean by These numbers are getting smaller, not larger -- 780 nm < 1.4 μm < 3 μm, and that's the correct progression, though I can't answer for the particular cutoff values. EEng 06:19, 8 January 2020 (UTC)

Tungsten Atoms to Regenerate?

"Halogen lamps are incandescent lamps filled with highly pressurized inert gas. This gas is combined with a small amount of halogen gas (bromine or iodine) which causes tungsten atoms to regenerate by lessening the evaporation of the filament. This leads..." Causes the tungsten atoms to regenerate? No. It called a halogen cycle and it just causes the redepositing of the tungsten back onto the filament rather than on the inside surface of the glass. — Preceding unsigned comment added by Longinus876 (talk • contribs) 05:52, 8 January 2020 (UTC)
