Shin watsa zafi yana da mahimmanci ga LEDs?

Dangane da yanayin zafin jiki, ana kiran LEDs a matsayin tushen haske "mai sanyi". Wannan saboda fitowar haske na LEDs da aka yi amfani da shi don hasken wuta ba ya ƙunsar radiation ta infrared, wanda ya bambanta da fitila mai ƙyalƙyali wanda ke samar da hasken infrared mai yawa (tabbas, wasu LEDs da aka yi amfani da su don ƙera ƙera abubuwa an tsara su ne don samar da makamashin infrared, amma a cikin wannan fitowar Waɗannan kuzari suna ba a dauke shi ba)). LEDs kuma gabaɗaya ana ɗaukarsu "sanyi" saboda suna fitar da haske ta hanyoyin da zasu iya amfani da su ta hanyar motsawar abubuwa masu zafi (kamar su tungsten filaments inincandescent lamp). Kodayake tsarin hasken LED ba ya samar da wani zafi mai annuri, LED ɗin har yanzu yana samar da zafi a mahaɗar, wanda dole ne a kwantar da shi ta hanyar isar da sako. Yi amfani da waɗannan hanyoyi don ɗaukar zafi daga radiator na na'urar kuma don samun ƙimar haske mafi girma da tsawon rayuwar na'urar ta hanyar amfani da LED a ƙarancin yanayin zafin jiki.

A wata sigar, fitilar LED ta hada da: matattarar zafi gami da jarkokin da aka fantsama a farfajiya daya; kuma mai gudanar da aiki akasin fin, mai gudanar da aiki wanda ya hada da lantarki mai hade guda biyu, daya ko fiye da wutan lantarki wadanda suka rabu da ingantaccen lantarki kuma an raba su tsakanin mai amfani da lantarki mai kyau, kuma daya ko sama da haka yana sanyawa kowane iri tsakanin mara kyau lantarki da kuma mai amfani da lantarki ; tsararren mai-haske mai haske wanda aka ɗora akan mai sarrafawa componentsunshi ya haɗa da layuka na LEDs. Waɗannan LEDs ɗin sun kasu kashi biyu waɗanda aka haɗa a layi daya. LEDs na kowane rukuni ana haɗa su ta lantarki a jere. Kowane LED ya haɗa da tabbatacce da mummunan jagoranci wanda aka gyara zuwa sandar sakawa mai sarrafawa kuma an haɗa ta da lantarki tare da kowane lantarki mai kyau. Wutar kafa da wutar lantarki mai jan kunne, madugu mai kyau na lantarki, suna hade ne ta hanyar lantarki zuwa kowane irin lantarki mai kyau; mummunan electrode yana hade ne da mararin lantarki.

Lokacin shigar da waɗannan tsarin a cikin aikace-aikace, buƙata don tabbatar da watsawar tsarin LED yana da mahimmanci. Dole ne a sami isasshen ma'anar tafiyar da zafi daga tsarin, ko don iska ta iska ta kwantar da dumi mai dumi. Sanya tsarin hasken LED a cikin karamin fili wanda yake da dan karamin yanayi na iya haifar da saurin tashin zafin jiki da kuma rashin iya aiki.
