LEDs na'urori ne masu sarrafa halin yanzu. Don tabbatar da daidaitaccen haske lokacin haɗa LEDs da yawa a layi daya, ana ƙarfafa ba da shawarar yin amfani da resistor mai iyakance halin yanzu a jere tare da kowane LED (Samfurin Da'ira A). Yin amfani da resistor guda ɗaya don LEDs da yawa a layi daya (Samfurin Da'ira B) ba a ba da shawara ba, saboda ɗan bambanci a cikin ƙarfin lantarki na gaba (VF) tsakanin kowane LED na iya haifar da bambanci mai mahimmanci a cikin halin yanzu, saboda haka, haske.

9. Abubuwan Ƙira da Bayanan Aikace-aikace

9.1 Gudanar da Zafi

Duk da yake na'urar tana da ƙarancin wutar lantarki (108mW matsakaici), daidaitaccen ƙirar thermal har yanzu yana da mahimmanci don dogaron dogon lokaci, musamman lokacin aiki kusa da matsakaicin ƙima ko a cikin yanayin zafi mai girma. Dole ne a yi la'akari da ƙimar rage ƙima na 0.45 mA/°C sama da 30°C don tabbatar da halin yanzu na gaba na DC bai wuce iyakokin aminci ba. Isasshen tazara akan PCB da yuwuwar iskar iska na iya taimakawa sarrafa zafin haɗuwa.

9.2 Ƙirar Da'ira don Daidaitaccen Hasken

Tsarin rarrabawa don ƙarfin hasken haske (Iv) da launi (x, y) siffa ce mai mahimmanci ga aikace-aikacen da ke buƙatar daidaiton launi ko haske. Masu ƙira yakamata su ƙayyade kwandon da ake buƙata lokacin yin oda. Bugu da ƙari, kamar yadda aka haskaka a sashin hanyar tuƙi, amfani da resistors na jere na kowane LED shine hanya mafi aminci don cimma daidaitaccen haske a cikin tsararrun LED masu yawa, yana rama da rarraba halitta a cikin siffar ƙarfin lantarki na gaba na LED.

9.3 Haɗin Injina

An ƙera samfurin don amfani da takamaiman mai riƙe na kusurwa mai dama (CBI). Dole ne masu ƙira su tabbatar cewa shimfidar wurin PCB ta ɗauki ƙafar mai riƙe da kuma yankin da aka ba da shawarar don guje wa gyaɗa (2mm daga gindin lensa). Umarnin siffantar jagora da ƙaramin ƙarfin ƙulle suna da mahimmanci don guje wa sanya damuwa na injina akan kunshin LED, wanda zai iya haifar da gazawa da wuri ko fashewar lensa.

10. Kwatance da Jagorar Zaɓi

LTW-1NHDR5JH231 yana ba da haɗin fitila ta T-1 ta daidaitawa tare da tsarin mai riƙe na musamman. Babban fa'idodinsa sun haɗa da sauƙin haɗawa da samuwar zaɓin kallon kusurwa mai dama ta hanyar mai riƙe. Cikakken tsarin rarrabawa yana ba da damar zaɓi daidai don aikace-aikacen inda launi ko daidaitawar ƙarfi ke da mahimmanci. Lokacin zaɓar LED, mahimman sigogi don kwatanta sun haɗa da ƙarfin hasken haske (Iv), kusurwar dubawa, ƙarfin lantarki na gaba (VF), da mahimman ƙimar ƙima masu alaƙa (halin yanzu, wutar lantarki, zafin jiki). Matsakaicin ƙarfin lantarki na gaba na wannan na'urar na 3.2V a 20mA ya zama gama gari ga fararen LEDs na InGaN, yana sa ya dace da daidaitattun wadatar wutar lantarki na matakin dabaru lokacin amfani da daidaitaccen resistor mai iyakance halin yanzu.
