Thyristor LED. Features ndi mfundo ya ntchito

Thyristor anatsogolera - izi ndi zopambana zina tsatanetsatane alipo lero, amene ntchito popanga zipangizo kuyatsa. Ubwino LED: moyo wautali ntchito, kumwa mphamvu otsika ndi miyeso yaing'ono.

Mfundo ntchito anatsogolera

chifukwa ndondomeko luminescence ndi recombination mabowo ndithu mlandu particles zoipa mlandu zoni pH-kusamba. zone Izi ndi mawonekedwe zipangizo awiri (semiconductors) ndi osiyana mphamvu panopa madutsidwe. Kuti akonze chowala yowala a dongosolo multilayer wa Chip ndi LED. kuwala ake akhoza ziwonjezeke kutsatira ndi mavuto amphamvu, koma ndi phindu lalikulu kwa diode panopa sangaone. kuwala LED zikhoza kusintha motsogozedwa ikuchepa. yomanga ake ndi ophweka, koma pa nthawi yomweyo, opanga ambiri sanena chinsinsi cha ulimi wa mankhwala ake.

Pakali pano, amakono anatsogolera tiristotny bwino kwambiri, chifukwa ranges ake dzuwa pakati pa 60 ndi 70%. Ngati Tikayerekeza incandescent nyali (dzuwa lomwe 5-7 kokha%) ndi kutsogozedwa, yotsirizira bwino kuposa pafupifupi khumi kuchulukitsa. Mawu a ntchito chimenecho zipangizo kuyatsa kuti ntchito kuwala emitting diode thyristor, ndi zaka khumi kuwala mosalekeza. ndalama mphamvu ntchito anatsogozedwa, poyerekeza ndi LDR pafupifupi 50% poyerekeza ndi incandescent - 85%.

The linanena bungwe kuwala kwa diodes ano akhoza kupikisana ndi IPF ndi HPS (ndi DNaZ). chiwerengerochi ndi wofanana 150 lm / W. Nthawi payback wa mababu LED - zaka 2-3. Kenako, otsala zaka khumi, inu kupulumutsa 85% ya magetsi ankadya mwezi uliwonse.

LEDs. makhalidwe a

LED, amene makhalidwe si analogues otsika, ndi ubwino izi:

• mu kupanga LEDs ntchito galasi, kotero owala nyali ya mtundu uwu ndi durability mkulu, kugwedera kukana ndi kudalilika;
• LED kugonjetsedwa kusinthasintha voteji ndi kunyeketsa 0.4-0.6 A yekha;
• Thyristor anatsogolera umagwira ntchito bwino kwambiri zinthu, ngakhale pa otsika kutentha kwambiri.

Kuyamba anatsogozedwa, amafuna mtengo ndithu diode mlatho, kuchititsa mtengo wa kuyatsa poyamba anali overpriced ndithu. Opanga anathetsa vutoli. Chojambula chithunzi lasinthidwa ndi m'malo thyristor triac dimmers akhala ntchito. Zotsatira zake zinali chipangizo ongokhala thyristors ziwiri zolumikizana mu kufanana, kauntala zikutanthauza. Chifukwa luso ichi, kufunika kwa diode mlatho palibe lero. chisankho Zimenezi zinachititsa kuti mankhwala otsika mtengo ndipo kwambiri chinawonjezeka mlingo chitetezo ndi khalidwe la katundu pa maziko a thyristors lapansi.

Thyristor anatsogolera chimagwiritsidwa ntchito popanga zipangizo kuyatsa. moyo utumiki yaitali ake, kudalirika ndi zothandiza ndikondwera ogula, monga chandeliers ndi zipangizo zina ndi LED-chiwalitsiro si ndalama, komanso tione wokongola kwambiri.
