什么(me)是紅外線燈管?

紅(hong)外(wai)線燈管(guan),也叫紅(hong)外(wai)線加熱燈管(guan),是將鎢(wu)絲伸入充氣的石英管(guan)(guan)中構(gou)成。鎢(wu)絲在交(jiao)流電壓作用下發熱并加熱石英管(guan)(guan)中的氣體,由此產生紅(hong)外(wai)線(xian)輻射。 石英近紅(hong)(hong)(hong)外(wai)(wai)、遠紅(hong)(hong)(hong)外(wai)(wai)燈采用透明或(huo)半(ban)透明石英玻璃作為燈管(guan)外(wai)(wai)殼(ke)可(ke)生產近紅(hong)(hong)(hong)外(wai)(wai)線(xian)或(huo)遠紅(hong)(hong)(hong)外(wai)(wai)線(xian)輻射(she)譜線(xian)。紅(hong)(hong)(hong)外(wai)(wai)線(xian)向外(wai)(wai)輻射(she),可(ke)以用來(lai)加(jia)熱。
