什么是紅外線燈管(guan)?
紅(hong)外(wai)線(xian)燈(deng)管,也叫紅(hong)外(wai)線(xian)加熱燈(deng)管,是將(jiang)鎢絲伸入(ru)充氣(qi)的石(shi)英管中構(gou)成。鎢絲在(zai)交流(liu)電壓(ya)作(zuo)用下發熱并加熱石(shi)英管中的氣(qi)體,由此產生紅外線輻(fu)射。 石英(ying)近紅(hong)外(wai)(wai)、遠(yuan)紅(hong)外(wai)(wai)燈采用(yong)透(tou)(tou)明(ming)或半透(tou)(tou)明(ming)石英(ying)玻璃作為燈管(guan)外(wai)(wai)殼可生產近紅(hong)外(wai)(wai)線或遠(yuan)紅(hong)外(wai)(wai)線輻射譜線。紅(hong)外(wai)(wai)線向外(wai)(wai)輻射,可以用(yong)來加熱。
