Mwenje wemota dzemotokari dzinowanzo umbwa nezvikamu zvitatu: girobhu remwenje, reflekisi uye girazi rinoenderana (astigmatism mirror).
1. girobhu
Magirobhu anoshandiswa mumagetsi emota incandescent bulbs, halogen tungsten bulbs, mwenje mutsva wekupenya kwearc uye zvichingodaro.
(1) Incandescent girobhu: filament yaro yakagadzirwa netambo yetungsten (tungsten ine nzvimbo yakakwirira yekunyungudika uye chiedza chakasimba).Munguva yekugadzira, kuitira kuti uwedzere hupenyu hwebasa rebhubhu, girobhu rinozadzwa negesi inert (nitrogen uye musanganiswa wayo wemagasi anert).Izvi zvinogona kuderedza kubuda kwetambo ye tungsten, kuwedzera tembiricha yefilament, uye kuwedzera kupenya kwakanaka.Chiedza chinobva mugirobhu reincandescent chine yellowish tinge.
(2) Tungsten halide mwenje: Tungsten halide mwenje girobhu inopinzwa muinert gasi mune imwe halide chinhu (senge iodine, chlorine, fluorine, bromine, nezvimwewo), uchishandisa musimboti we tungsten halide recycling reaction, kureva, the gaseous tungsten inoputika kubva mufilament inopindirana nehalogen kuti ibudise tungsten halide inoputika, iyo inopararira kune nzvimbo yakakwirira yekushisa pedyo nefilament, uye yakasvibiswa nekupisa, kuitira kuti tungsten idzoserwe kune filament.Iyo halogen yakaburitswa inoramba ichipararira uye kutora chikamu mune inotevera kutenderera kuita, saka kutenderera kunoenderera, nekudaro ichidzivirira kubuda kwe tungsten uye kudzima kwegirobhu.Tungsten halogen mwenje girobhu saizi idiki, girobhu regirazi rakagadzirwa negirazi requartz rine tembiricha yakakwira uye simba remuchina, pasi pesimba rimwechete, kupenya kwetungsten halogen mwenje ndeye 1.5 nguva yerambi reincandescent, uye hupenyu huri 2 kusvika 3 nguva refu.
(3) Mwenje mutsva wearc unopenya: Mwenje uyu hauna tambo yechinyakare mugirobhu.Pane kudaro, ma electrode maviri anoiswa mukati mequartz tube.Iyo chubhu inozadzwa nexenon uye trace simbi (kana simbi halides), uye kana paine yakakwana arc voltage pa electrode (5000 ~ 12000V), gasi rinotanga kuita ionize uye kuitisa magetsi.Maatomu egasi ari mukunakidzwa uye anotanga kuburitsa chiedza nekuda kwekuchinja kwesimba remaerekitironi.Mushure me 0.1s, shoma shoma ye mercury vapor inoputika pakati pe electrode, uye simba rekushandisa rinobva raendeswa kune mercury vapor arc discharge, uye rinozoendeswa kune halide arc rambi mushure mokunge tembiricha yakwira.Mushure mekunge chiedza chasvika kune yakajairika tembiricha yekushanda yegirobhu, simba rekuchengetedza arc kubuda rakaderera kwazvo (anenge 35w), saka 40% yesimba remagetsi rinogona kuponeswa.
