Zisebenza njani izibane zeLed Street

Zisebenza njani izibane zesitalato ze-LED?

Ukukhanya kwesitalato kuye kwafika kude ukususela kwiintsuku zokuqala zezibane zegesi kunye ne-incandescent bulbs. Namhlanje, izibane zesitalato ze-LED zisemgangathweni opheleleyo-kwaye ngesizathu esihle. Awonga amandla, ahlala ixesha elide kwaye aneendleko ezifanelekileyo. Enyanisweni, iindawo ezininzi zasezidolophini emhlabeni jikelele ziye zatshintshela ekukhanyeni kwesitrato se-LED ukuze kugcinwe ukusetyenziswa kwamandla kunye nokunciphisa ukukhutshwa kwekhabhoni.

Kodwa zisebenza njani izibane zesitalato ze-LED? Masingene kwinzululwazi kunye neteknoloji emva kwale mimangaliso yale mihla yokukhanyisa.

Isihlokwana: Ukusuka kwi-Incandescent ukuya kwi-LED

Phambi kokuba singene kwindlela ezisebenza ngayo izibane zesitrato ze-LED, makhe sijonge ngokukhawuleza kwimbali yokukhanyisa ezitalatweni. Ekuqaleni kweminyaka yee-1800, izibane zegesi zazikhanyisa izitrato zedolophu. Zange kube ngasekupheleni kweminyaka yoo-1800 apho izibane zasezitalatweni zombane zaye zavela. Nangona kunjalo, iinguqulelo zokuqala zezitrato zombane zasebenzisa izibane ze-incandescent, ezingenamandla kakhulu okanye zihlala ixesha elide.

Emva koko, ngo-1960, i-diode yokuqala yokukhupha ukukhanya (i-LED) yenziwa. Nangona kunjalo, bekungekho de kwaba ngoo-1990 apho ukukhanya kwe-LED kwaqala ukwenza indlela yayo kwishishini lokukhanyisa ezitalatweni. Ngoku, izibane zesitalato ze-LED zisemgangathweni kwizixeko ezininzi kwihlabathi liphela.

Isihlokwana: Amacandelo aPhambili kwizibane zesitalato ze-LED

Ngaphambi kokuba sijonge indlela izibane ze-LED ezisebenza ngayo, kufuneka siqonde amacandelo asisiseko kwezi zibane zokukhanyisa. Nanga amacandelo amane aphambili:

-Iitshiphusi ze-LED: Le yimithombo emincinci yokukhanya evelisa ukukhanya kwangempela.

- Umqhubi we-LED: Eli candelo lilawula amandla anikezelwa kwii-chips ze-LED kwaye inceda ukuqinisekisa imveliso ehambelanayo.

- I-Heat sink: Izibane zesitrato ze-LED zivelisa ubushushu, ngoko ke i-heat sink iyadingeka ukuyichitha kwaye igcine izibane ekutshiseni.

- Inkqubo ye-Optical: Oku kubandakanya i-reflector kunye ne-lens, enceda ukuqondisa ukukhanya apho kufuneka khona.

Isihlokwana: Inzululwazi ngasemva kwezibane zesitalato ze-LED

Ke, zisebenza njani izibane zesitalato ze-LED? Konke kuhla kwisayensi yee-semiconductors. Itekhnoloji ye-LED isebenzisa i-semiconductors ukuguqula amandla ombane abe ukukhanya. Xa umbane uhamba nge-semiconductor, ukhupha amandla ngendlela yeefotoni. Umbala wokukhanya uxhomekeke kuhlobo lwe-semiconductor esetyenzisiweyo.

Ii-LED zinamandla ngakumbi kunezibane ze-incandescent kuba ziguqula phantse onke amandla eziwasebenzisayo ekukhanyeni. I-incandescent bulbs, ngakolunye uhlangothi, ivelisa ubushushu obuninzi, obuchitha amandla. Oku kwenza izibane zesitrato ze-LED zibe neendleko ezingaphezulu kunezo zangaphambili ze-incandescent.

Isihlokwana: Izinto eziluncedo kwizibane zesitalato ze-LED

Izibane ze-LED zesitrato zibonelela ngenani leenzuzo ngaphezu kwezinye iintlobo zezitrato. Nazi ezinye zezibonelelo eziphambili:

-Amandla awonga: Izibane zasezitalatweni ze-LED zisebenzisa amandla amancinci kuneebhalbhu ze-incandescent kunye neeglowubhu zefluorescent.

- Ixesha elide: Izibane zesitrato ze-LED zinokuhlala ukuya kwiiyure ze-100,000, ezide kakhulu kunezinye iintlobo zokukhanyisa.

- Ukugcinwa okuphantsi: Ngenxa yokuba izibane zesitrato ze-LED zihlala ixesha elide, zifuna ukulungiswa okuncinci kunezinye iindidi zezitrato.

- Ukukhutshwa okuphantsi: Izibane ze-LED zesitrato zikhupha i-CO2 encinci kakhulu kunye nezinye izinto ezingcolileyo kunezinye iindidi zezitrato.

- Ukuqondisa: Izibane zesitalato ze-LED zinokuqondiswa ngokuchanekileyo kunezinye iintlobo zokukhanyisa, oku kuthetha ukuba zinokukhanyisa iindawo ezithile ngokufanelekileyo.

Isihlokwana: Usetyenziso lwezibane zesitalato ze-LED

Izibane zesitrato ze-LED zisetyenziswa kwiindawo ezahlukeneyo, ukusuka kwiidolophu ezinkulu ukuya kwiindlela ezisemaphandleni. Nazi ezinye zezona zicelo zixhaphakileyo zezibane zesitrato ze-LED:

- Izitalato zesiXeko: Izixeko ezininzi ezikhulu kwihlabathi jikelele ziguqukele kwizibane zesitrato ze-LED ukunciphisa ukusetyenziswa kwamandla kunye neendleko eziphantsi.

- Iindlela ezihamba phambili: Izibane zesitrato ze-LED zisetyenziselwa uhola wendlela kunye neenkqubo zangaphakathi ukubonelela ngokubonakala okungcono kunye nokunciphisa iingozi.

- Iindawo zokuhlala: Izibane zasezitalatweni ze-LED zikwathandwa kakhulu kwiindawo zokuhlala kuba zinokujoliswa ekukhanyiseni iindawo ezithile ngaphandle kokuchitheka kwiindawo ezikufutshane.

- Iindawo zokupaka: Iindawo ezininzi zokupaka zikhanyiswe ngezibane zasezitalatweni ze-LED kuba azibizi kakhulu kwaye ziwonga amandla.

Isihlokwana: Ekuqukumbeleni

Izibane zesitrato ze-LED ziyinto entsha engakholelekiyo kwindawo yokukhanyisa. Amandla ombane, ahlala ixesha elide kwaye angabizi kakhulu, okwenza kube lula kwiintlobo ezahlukeneyo zezicelo. Ngokuqonda ukuba zisebenza njani izibane zesitrato ze-LED kunye nezibonelelo eziphambili ezinikezelayo, unokuyiqonda ngcono impembelelo abanayo kwizixeko kunye needolophu kwihlabathi liphela.
