2. Tsari da Girman Injiniya

Haɗin fitilar LED yana cikin mai riƙe na filastik PA9T baƙi. An ba da takamaiman girman tsari a cikin zane-zanen injiniya da ke cikin takardar tushe. Muhimman bayanan injiniya sun haɗa da:

• Duk manyan girmansu an ƙayyade su a cikin milimita, tare da ƙimar ƙima yawanci a ±0.25mm sai dai idan an faɗi.
• Bangaren LED da kansa yana samuwa a launin shudi ko ja, an rufe shi da ruwan tabarau mai watsawa fari.
• Yana da mahimmanci a lura cewa duk ƙayyadaddun bayanai na iya canzawa ba tare da sanarwa ba.

3. Matsakaicin Matsakaicin Ƙimar

Waɗannan ƙimar suna bayyana iyakokin da za su iya haifar da lalacewar na'urar na dindindin. Duk ƙimar an ƙayyade su a yanayin zafin yanayi (TA) na 25°C.

4. Halaye na Lantarki da na Gani

Ana auna waɗannan halaye a TA=25°C kuma suna wakiltar aikin na'urar na yau da kullun a ƙarƙashin ƙayyadaddun yanayin gwaji.

Muhimman Bayanin Kula:Ana auna ƙarfin haske tare da tacewa wanda yake kusan amsawar ido na CIE photopic. Kusurwar dubawa (2θ1/2) ita ce cikakkiyar kusurwar inda ƙarfin ya ragu zuwa rabin ƙimar axial. Ba a ƙera na'urar don aiki a ƙarƙashin ƙarfin lantarki na baya ba; yanayin gwajin IR ne kawai don siffanta.

5. Ƙayyadaddun Tsarin Rarrabawa

Don tabbatar da daidaito a aikace, ana rarraba LED ɗin zuwa kwandon asusu bisa ga mahimman ma'auni. An yiwa alamar lambar kwandon akan marufi.

Gargadi:Wuce gona da iri na yawan zafin solder ko lokutan na iya haifar da nakasar ruwan tabarau ko gazawar LED mai ban tsoro.

7. Lankwalan Aiki da Bayanan Hotuna

Takardar bayanin tushe ta haɗa da lankwalan aiki na yau da kullun waɗanda ke da mahimmanci don cikakken binciken ƙira. Waɗannan zane-zanen suna wakiltar alaƙar tsakanin mahimman ma'auni ta gani, suna ba da fahimta fiye da bayanan tebur.

7.1 Lankwalan Halaye na Yau da Kullun

Yayin da ba a sake yin takamaiman zane-zanen a cikin sigar rubutu a nan ba, takardar bayanin tana ƙunshe da shirye-shirye don waɗannan alaƙar:

• Halin Gaba vs. Ƙarfin Lantarki na Gaba (I_F-V_F):Wannan lanƙwasa yana nuna alaƙar exponential na halayen diode na yau da kullun. Ga duka LED ja da shudi, ƙarfin lantarki yana ƙaruwa da logarithmic tare da halin yanzu. Masu ƙira suna amfani da wannan don tantance ƙarfin lantarki da ake buƙata don halin aiki da ake so, la'akari da bambancin da aka nuna a cikin teburin rarrabawar V_F.
• Ƙarfin Hasken vs. Halin Gaba (I_v-I_F):Wannan shirin yana nuna yadda fitar da haske ke ƙaruwa tare da halin tuƙi. Gabaɗaya yana da layi a cikin kewayon aikin da aka ba da shawarar amma zai cika a manyan halaye. Zanen yana taimakawa wajen zaɓar halin da ya dace don cimma haske da ake nufi yayin kiyaye inganci da zama cikin cikakkiyar matsakaicin ƙimar.
• Ƙarfin Hasken vs. Yanayin Yanayi (I_v-T_A):Fitar da hasken LED yana da alaƙa da juna tare da zafin haɗuwa. Wannan lanƙwasa yana ƙididdige raguwar ƙarfin haske yayin da yanayin yanayi (kuma saboda haka haɗuwa) ya tashi. Yana da mahimmanci ga aikace-aikacen da ke aiki a manyan yanayin zafi ko inda ake buƙatar haske mai daidaito.
• Rarraba Ƙarfin Bakan Dangin:Waɗannan zane-zanen na LED ja da shudi suna nuna ƙarfin hasken da aka fitar a cikin bakan tsawon tsawon. Lanƙwasa LED ja zai kai kololuwa a kusan 632nm, yayin da shudi ya kai kololuwa a kusan 468nm. Faɗin waɗannan kololuwar, wanda aka nuna ta hanyar ma'aunin Rabin Faɗin Bakan (Δλ), yana shafar tsaftar launi.

Tuntubar waɗannan lankwalan yana ba injiniyoyi damar yin samfurin halayen LED a ƙarƙashin yanayin da ba na daidaito ba (misali, halaye na tuƙi daban-daban ko zafin jiki) da kuma ƙirar da'irori masu ƙarfi waɗanda ke rama bambance-bambancen aiki.

8. Ƙayyadaddun Kunshin

Ana ba da ɓangaren a cikin kunshin da aka ƙera don sarrafawa ta atomatik da kuma karewa daga danshi da fitar da lantarki (ESD). Cikakken ƙayyadaddun kunshin, gami da girman reel, faɗin tef, girman aljihu, da kuma fuskantarwa, an yi cikakken bayani a cikin zanen da ya dace a cikin takardar tushe. Wannan bayanin yana da mahimmanci don saita injunan ɗauka da sanyawa a cikin layukan haɗawa ta atomatik.

9. Bayanin Aikace-aikace da Abubuwan Ƙira

9.1 Tuƙi LED

Koyaushe tuƙi LED ta amfani da tushen halin yanzu na dindindin ko resistor mai iyakance halin yanzu a jere tare da tushen ƙarfin lantarki. Yin amfani da tushen ƙarfin lantarki kawai yana haifar da haɗarin guduwar zafi da lalata LED. Ƙimar resistor na jere (R_s) za a iya ƙididdige shi ta amfani da Dokar Ohm: R_s= (V_supply- V_F) / I_F. Yi amfani da matsakaicin V_Fdaga takardar bayanin don wani kwandon don tabbatar da isasshen halin yanzu a kowane yanayi. Misali, don tuƙi LED shudi daga wadata 5V a 10mA, yana ɗauka matsakaicin V_Fna 3.6V: R_s= (5V - 3.6V) / 0.01A = 140Ω. Resistor na daidaitaccen 150Ω zai zama zaɓi mai aminci.

9.2 Gudanar da Zafi

Ko da yake raguwar wutar lantarki yana da ƙasa (52-76mW), ingantaccen ƙirar zafi yana tsawaita tsawon rai da kuma kiyaye haske. Tabbatar cewa PCB yana da isasshen yanki na tagulla da aka haɗa da jagororin LED don zama mai sanyaya zafi. Kauce wa sanya LED kusa da wasu abubuwan da ke haifar da zafi. Yin aiki a ko kusa da matsakaicin zafin haɗuwa zai hanzarta raguwar lumen.

9.3 Polarity da Fuskantarwa

LED ɗin rami na rami na'urori ne masu polarized. Jagoran da ya fi tsayi yawanci shine anode (tabbatacce). Gidan na iya samun gefe mai lebur ko wasu alamomi kusa da jagoran cathode. Shigar da ba daidai ba zai hana LED haskakawa kuma yin amfani da ƙarfin lantarki na baya sama da 5V na iya lalata shi.

9.4 Tsaftacewa

Idan ana buƙatar tsaftacewa bayan solder, yi amfani da kaushi na barasa kawai kamar isopropyl alcohol (IPA). Kauce wa masu cire kwarara ko tsaftacewa ta ultrasonic, saboda waɗannan na iya lalata ruwan tabarau na filastik ko gida.

10. Kwatancen da Jagorar Zaɓi

Lokacin zaɓar LED mai nuna alama, mahimman abubuwan yanke shawara sun haɗa da:

• Launi da Tsawon Tsawon:Zaɓi bisa ga alamar da ake buƙata (misali, ja don gargaɗi/faɗakarwa, shudi don matsayi). Yi la'akari da kwandon tsawon tsawon don aikace-aikacen da ke da mahimmanci na launi.
• Hasken (Ƙarfin Hasken):Zaɓi kwandon ƙarfin da ya dace don nisan dubawa da yanayin hasken yanayi. Manyan kwandon (misali, HJ don shudi) suna da haske amma na iya cinye ɗan ƙaramin wutar lantarki don halin yanzu ɗaya saboda V na yau da kullun_F correlation.
• Kusurwar Dubawa:Kusurwar dubawa 100° tana ba da tsarin haske mai faɗi, mai watsawa wanda ya dace da alamomin panel da ake duba daga kusurwoyi daban-daban. Don ƙarin haske mai mai da hankali, ana buƙatar ruwan tabarau tare da ƙunƙuntacciyar kusurwar dubawa.
• Ƙarfin Lantarki na Gaba:Mafi girma V na LED shudi_F(~3.2V na yau da kullun) idan aka kwatanta da ja (~2.4V na yau da kullun) yana da tasiri ga ƙirar wadata, musamman a cikin na'urorin da ake amfani da baturi. V_Fkwandon yana ba da damar zaɓar LED tare da madaidaicin daidaiton ƙarfin lantarki don tsarin tuƙi na layi daya.

Wannan fitilar LED ta rami tana ba da ingantaccen mafita, mai sauƙin haɗawa don buƙatun alamar PCB na daidaitaccen, tare da cikakken rarrabawa yana ba da damar zaɓi daidai don daidaitaccen aiki a cikin samar da girma.
