Ibyerekeye umushoferi wa LED

Intangiriro kuri LED shoferi

LED iranga-ibyumviro bya semiconductor ibikoresho bifite ubushyuhe bubi.Kubwibyo, bigomba gutekerezwa no kurindwa mugihe cyo gusaba, biganisha ku gitekerezo cya shoferi.Ibikoresho bya LED bifite ibyangombwa bisabwa kugirango imbaraga zo gutwara.Bitandukanye n'amatara asanzwe yaka, LED irashobora guhuzwa neza na 220V AC itanga amashanyarazi.

Imikorere yumushoferi wa LED

Ukurikije amategeko y’amashanyarazi ya gride hamwe nibisabwa biranga amashanyarazi ya LED, ingingo zikurikira zigomba gutekerezwaho muguhitamo no gushushanya amashanyarazi ya LED:

Kwizerwa cyane: cyane nkumushoferi wamatara yo kumuhanda LED.Kubungabunga biragoye kandi bihenze ahantu hirengeye.

Ubushobozi buhanitse: Imikorere ya LEDs igabanuka hamwe nubushyuhe bwiyongera, bityo gukwirakwiza ubushyuhe nibyingenzi cyane cyane mugihe amashanyarazi yashizwe mumatara.LED nigicuruzwa kizigama ingufu gifite ingufu nyinshi zo gutwara, gukoresha ingufu nke hamwe nubushyuhe buke mumatara, bifasha kugabanya ubushyuhe bwitara ryamatara no gutinza urumuri rwa LED.

Impamvu zikomeye: Ikintu cyingufu nicyo gisabwa ingufu za gride kumuzigo.Mubisanzwe, nta bipimo byateganijwe kubikoresho byamashanyarazi biri munsi ya watt 70.Nubwo ibintu byingufu zumuriro umwe wamashanyarazi make ari bike cyane, ntabwo bigira ingaruka nke kuri gride.Ariko, niba amatara yaka nijoro, imizigo isa nayo izaba yibanze cyane, bizatera imitwaro ikomeye kuri gride.Bavuga ko kubashoferi ba LED ya 30 kugeza 40 watt, hashobora kuba hari indangagaciro zisabwa kubintu byingufu mugihe cya vuba.

LED ihame ryumushoferi

Umubano uhetamye hagati yimbere ya voltage igabanuka (VF) niterambere ryimbere (NIBA).Birashobora kugaragara uhereye kumurongo ko iyo voltage yimbere irenze igipimo runaka (hafi 2V) (mubisanzwe bita kuri voltage), birashobora kugereranywa ko NIBA na VF biringaniye.Reba imbonerahamwe ikurikira kubiranga amashanyarazi biranga LED nini cyane.Birashobora kugaragara kumeza ko hejuru cyane NIBA ya LED yaka cyane irashobora kugera kuri 1A, mugihe VF isanzwe ari 2 kugeza 4V.

Kubera ko urumuri ruranga LED rusobanurwa nkibikorwa byubu aho kuba imikorere ya voltage, ni ukuvuga, umurongo uhuza umurongo uri hagati ya luminous flux (φV) na NIBA, ikoreshwa ryumwanya uhoraho utwara umushoferi urashobora kugenzura neza umucyo .Mubyongeyeho, imbere ya voltage igabanuka ya LED ifite intera nini (kugeza 1V cyangwa irenga).Nkuko bigaragara kuri VF-NIBA umurongo mugishushanyo cyavuzwe haruguru, impinduka nto muri VF izavamo impinduka nini muri NIBA, bivamo umucyo mwinshi nimpinduka nini.

Isano iri hagati yubushyuhe bwa LED na luminous flux (φV).Igishushanyo gikurikira kirerekana ko luminous flux ihwanye nubushyuhe.Amashanyarazi atemba kuri 85 ° C ni kimwe cya kabiri cyumucyo utanga kuri 25 ° C, naho urumuri rumuri kuri 40 ° C ni inshuro 1.8 zumucyo kuri 25 ° C.Imihindagurikire yubushyuhe nayo igira ingaruka runaka kumuraba wa LED.Kubwibyo, ubushyuhe bwiza bwo gukwirakwiza ni garanti yerekana ko LED ikomeza kumurika.

Kubwibyo, gukoresha amashanyarazi ahoraho kugirango utware ntibishobora kwemeza urumuri rwa LED, kandi bigira ingaruka kumyizerere, ubuzima no kumurika kwa LED.Kubwibyo, LED yaka cyane isanzwe itwarwa nisoko ihoraho.
