A na-ejikarị ya na-acha ọkụ na-enweghị isi atọ: bọlbụ ọkụ, nke na-atụgharị uche na enyo enyo (Astigmatism enyo).
1. Bootb
The bulbs ejiri na-acha odo odo na-enweghị bọlbụ, halogen Tungsten, oriọna ọhụrụ dị elu elu igwe na nke dị iche iche.
(1) Incandont Bulb: a na-eji amingsten waya (tungsten nwere isi na-agbaze na ìhè siri ike). N'oge ị na-emepụta ihe, iji bulie ndụ ọrụ nke bọlbụ, bọlbụ jupụtara na gas gas (nitrogen na ngwakọta ya nke ekikere ikuku). Nke a nwere ike belata nsị nke wagsten waya, mụbaa okpomọkụ nke filament, ma kwalite arụmọrụ luminoous. Ìhè ahụ sitere na bọlbụ bọlbụ nwere eriri na-acha odo odo.
(2) A na-etinye oriọna nke Tungsten Hayb na gas na-emebi ihe na-emegharị emegharị, nke ahụ, na-emegharị ya na-emegharị ya Mgbasa na nnukwu ọnọdụ okpomọkụ dị nso na filament ahụ, ma na-ama ifuru, nke mere na a lọghachiri Tursten na filament ahụ. Ndị a tọhapụrụ Halogen na-aga n'ihu na mmeghachi omume okirikiri na-esote, yabụ okirikiri na-aga n'ihu, si otú ahụ gbochie mkpochapụ bọl. A na-eji ígwè na-eguzosi ike, na bọlbụ na-eguzogide na oriọna dị elu bụ ihe dị elu.
(3) oriọna arc ọhụrụ dị elu: oriọna a enweghị ọdịnala na bọlbụ. Kama nke ahụ, a na-etinye elektrọnik n'ime n'ime mmiri quartz. Tube ahụ jupụtara na Xenon ma na-achọpụta ọla (ma ọ bụ igwe na-eme ihe), na mgbe enwere ike voltaji (5000V) 12000v), gas na-amalite ionize na omume ọkụ eletrik. Atọns gas dị na steeti nwere obi ụtọ wee malite na ọkụ Emit n'ihi ngbanwe ume nke electrons. Mgbe 0.11s, a na-ebugharị obere oghere nke mercury n'etiti electrodes, a na-ebugharị ikike ọkọnọ ọkụ na mgbaasị arc ahụ ozugbo, wee bufee ya na mgbanaka egweri ahụ mgbe okpomoku na-ebilite. Mgbe ìhè ahụ ruru ọrụ okpomọkụ nke bọlbụ, ike nke idowe nke arc dị ala (ihe dị ka 35W), yabụ 40% nke ike eletrik ga-azoputa.
