Yeyiphi imibala yokukhanya yelitha yokukhanya ngaphandle?

Ngaba uyawazi umbala wokukhanya wengaphandleI-Flashlights? Abantu abaqhelekileyo bangaphandle baya kulungiselela isibane okanye ephathwayointloko. Nangona kunqabile, njengoko ubusuku buwe, olu hlobo lwento lunokuzithatha ngokwenyani kwimisebenzi ebalulekileyo. Nangona kunjalo, izibane zeflekis zikwanazo neekhrayitheriya ezininzi zovavanyo kunye nokusetyenziswa. Ngokumalunga noku, abantu basenokunganikeli ingqalelo kakhulu. Okulandelayo, kwimbono yombala wokukhanya kwesibane, ndiza kwabelana nawe ngesibane semibala eyahlukeneyo kumaphandle. Isenokungabi luncedo, kodwa ikwachanekile ukwandisa intsimi yombono kwimeko kaxakeka!

Isibane esimhlophe

Qala intetho malunga nokukhanya okuncinci okuqhelekileyo. Ukuthandwa kokukhanya okuMhlophe kwaqala ukusebenzisa i-LED ye-LED ye-flashlights kule minyaka idlulileyo. Ukukhanya okumhlophe kufuphi nokukhanya kwelanga, kwaye ukukhanya okumhlophe ebumnyameni kuyahambelana namava abonakalayo ngamehlo ethu, ngenxa yoko ayithathi thuba lamehlo, kwaye kufanele ukuba lolona phawu lombala oluhle lwamehlo. Ngapha koko, ukukhanya okumhlophe kuphakamile kunezinye izibane zemibala ngokubhekisele ekuqaqambekeni kunye nobushushu bemibala, ukunika abantu imvakalelo eqaqambileyo. Ke ngoko, kwimisebenzi yangaphandle, ukukhanya okumhlophe kusetyenziswa ngokubanzi ngokuhamba ebusuku kunye nokukhanya kwenkampu.

ukukhanya okulula

Isibane esiphuzi esikhankanywe apha ayisiyiyo i-tyheli etyheli ekhutshelwe izibane zemveli zisebenzisa iibhalbhu ze-incandescent. Ngokuthetha ngokungqongqo, ukukhanya kukhutshelwa yi-Incandescent bubs kunohlobo olukhanyisiweyo olumhlophe, kodwa lufudumezekile ngenxa yobushushu obuphantsi. Ukukhanya okuMhlophe ngumxube obomvu, orenji, tyheli, luhlaza, luhlaza, ingot, kunye nemfusa. Ngumbala oxutywe. Ukukhanya okutyhoziyo apha ngumbala omnye ophuzi ngaphandle kokuxuba. Ukukhanya kubaluleke kakhulu i-elektromagnetic yamaza e-wavelength enye. Xa i-elektromagnetic wave eshukumisa emoyeni, ineefom ezintlanu: imithanga ngqo, ukucingisisa, ukuhambisa, ukusasaza, kunye nokusasaza. Ngenxa ye-wavelength yayo ethile, ukukhanya kwetyheli elula kakhulu kucocekile kwaye kusasazeke kukukhanya okubonakalayo. Oko kukuthi, ukukhanya okulula kunento enamandla kakhulu, kwaye phantsi kweemeko ezifanayo, ukukhanya kwetyheli kuhamba phambili kunolunye uphawu olubonakalayo. Akunzima ukuchaza ukuba kutheni izibane zendlela zisebenzisa ukukhanya okubi kunye nezibane zemoto zisebenzisa ukukhanya okulula? Imeko yangaphandle ebusuku ihlala ihamba kunye ne-vapor ye-vapor kunye nempazamo. Kwimeko enjalo, ukukhanya kwesibaneigqibelele.

Isibane esibomvu

Ukukhanya okubomvu kukukukhanya kombala okusetyenzisiweyo kwiingcali zangaphandle, ngakumbi kumazwe aseYurophu naseMelika. Imidlalo yokuzingela iyathandwa kumazwe amaninzi aseYurophu naseMelika, kwayeI-flashlight ebomvu ziyathandwa zivela kwi-European naseMelika zokuzingela. I-retina yomntu iqulethe izicubu ezimbini zefoto: iiseli zeCone kunye neeseli zeROD. Iiseli ze-cone ukwahlula imibala, kwaye iiseli zentonga yahlulahlula i-contours. Isizathu sokuba abantu bakwazi ukuvelisa imbonakalo yombala kungenxa yeeseli zeCone kwi-retina. Izilwanyana ezininzi zineentonga okanye zimbalwa ii-cones, ezikhokelela ekungakhathaliyo ukuba kugcinwe umbala okanye akukho mbonakalo yombala. Uninzi lwexhoba eliphantsi kwemipu yabazingeli baseYurophu nelaseMelika luhlobo lwesilwanyana, nto leyo engenakukhethekileyo ukukhanya okubomvu. Xa bezingela ebusuku, banokusebenzisa ngokunzulu izibane ezibomvu ukutshayela ixhoba ngaphandle komntu ocinga, ukuphucula impumelelo ekuzingeleni. .

Inzondelelo yangaphandle engaphandle kunqabile ukuba ibe namava okuzingela, kodwa ukukhanya okubomvu kusenombala oluncedo kakhulu kwimisebenzi yangaphandle. Amehlo aguqukayo - xa umbala wotshintsho lokukhanyisa, amehlo afuna inkqubo yokuhlengahlengiswa kunye nohlengahlengiso kwi-Gapt. Zimbini iintlobo zotshintsho: Ukulungelelaniswa okumnyama kunye nokulungelelanisa ukukhanya. Ukulungelelaniswa okumnyama yinkqubo evela ekukhanyeni ukuya kumnyama, okuthatha ixesha elide; Ukulungelelaniswa okukhanyayo yinkqubo evela emnyama ukuya ekukhanyeni, nto leyo ithatha ixesha nje elifutshane. Xa sisebenzisa isibane esimhlophe esikhanyayo kwimisebenzi yangaphandle, xa umgca wokujonga okuqaqambileyo kwindawo emnyama "ye-onling", ivumela ukuba siziphathe ixesha elifutshane ", sisivumela ukuba siziphathe kakuhle amehlo ethu kwaye sisebenza ebusuku xa sisebenza ebusuku.

isibane esiluhlaza

Uninzi lwezinto ezimhlophe zokukhuphela i-Whitels enyanisiweyo ivelisa ukukhanya okumhlophe ngokukhokelela kwi-Plarading Polster nge-Blue ukukhanya, ngoko ke ukukhanya kwe-LED kuquka izinto ezibukhali eziblowu. Ngenxa yokurhoxisa okuphezulu kunye nenqanaba lokuqhekeka okukhanyayo oluhlaza okwesibhakabhaka xa idlula emoyeni, idla ngokuhamba kude, oko kukuthi, ukungena nokulingela ukukhanya kwe-Lhini kubuthathaka. Ukanti, iblu-ray ine-knack yayo eyodwa. Izilwanyana zegazi amabala avuthayo ngokukhanya. Ukusebenzisa olu phawu lukhanyiso oluhlaza okwesibhakabhaka, inzondelelo yaseYurophu ne-Earopunias yokuzingela i-flashkhash ukukhanya ukulandela igazi lexhoba lexhoba, ukuze ekugqibeleni liqokelele ixhoba.
