Babban abin da ya bambanta wannan jerin shine amfani da fakitin EMC a cikin siffar tsaka-tsaki na 3030. Idan aka kwatanta da fakitin filastik na al'ada (PPA/PCT), EMC yana ba da mafi girman yawan isar da zafi da juriya ga zafi mai girma da bayyanar UV, wanda ke haifar da ingantaccen kiyaye lumen da kwanciyar hankali na launi a tsawon rayuwar samfurin. Wannan yana ba da damar LED don tuƙi a manyan igiyoyin kuzari (har zuwa 200mA) fiye da LED na tsaka-tsaki na al'ada, yana haɗa gibin zuwa na'urori masu ƙarfi yayin kiyaye farashi da fa'idodin gani na dandalin tsaka-tsaki.

8. Tambayoyin da ake yawan yi (Bisa Ma'auni na Fasaha)

Q: Menene ainihin amfani da wutar lantarki a wurin aiki na yau da kullun?

A: A I_F= 150mA da V_F= 6.8V, ƙarfin lantarki na yau da kullun shine 150mA * 6.8V = 1.02W.

Q: Ta yaya zan zaɓi daidaitaccen CCT da kwandon fitarwa don aikin na?

A: Zaɓi CCT (misali, 3000K farin dumi, 4000K farin tsaka-tsaki, 6500K farin sanyi) bisa ga yanayin da ake so. Zaɓi kwandon fitarwa bisa ga manufar fitar lumen kowane LED, la'akari da teburorin binning da ƙayyadaddun ma'auni. Don tsararrun daidaitattun, ƙayyade ƙwaƙƙwaran kwandon shara guda ɗaya don duka launi da fitarwa.

Q: Zan iya tuƙa wannan LED a 200mA akai-akai?

A: Kuna iya, amma kawai idan an kiyaye zafin haɗin gwiwa ƙasa da matsakaicinsa na 115°C. Wannan yana buƙatar ingantaccen sarrafa zafi. Dubi Hoto na 8; a yanayin yanayi na 85°C, matsakaicin izinin igiyar kuzari don tsarin tare da R_j-a=45°C/W kusan 89mA ne kawai. Saboda haka, tuƙi a 200mA yana yiwuwa ne kawai a cikin yanayin sanyi sosai, ƙananan yanayin yanayi.

9. Misalin Ƙira da Amfani

Yanayi: Ƙirar Maye gurbin Ƙwalwar LED 1200 lm (A19).

Manufa: 1200 lm, 2700K CCT, shigarwar AC 120V.

Matakan Ƙira:

1. Zaɓin LED:Zaɓi samfurin T3C27821C-**AA (2725K CCT). Zaɓi babban kwandon fitar haske (misali, 2D ko 2E) don matsakaicin fitarwa kowane LED.

2. Ƙididdiga na Yawa:Ana ɗauka 115 lm/LED (na yau da kullun daga kwandon shara 2D), kusan 1200 lm / 115 lm/LED ≈ ana buƙatar LED 11.

3. Ƙirar Lantarki:Saita LED 11 a cikin jerin jerin gwano. Jimillar ƙarfin lantarki na gaba a 150mA zai zama ~11 * 6.8V = 74.8V. Zaɓi direban LED mai zaman kansa, mai ƙarfi na yau da kullun tare da fitarwa mai dacewa da 74.8V, 150mA.

4. Ƙirar Zafi:Jimillar ƙarfin ƙarfi shine ~1.02W/LED * 11 LED = 11.22W. Babban yanki zafi ne. Dole ne ƙwalwar ta haɗa da heatsink na aluminum ko makamancin haka don kiyaye zafin wurin siyar da LED ƙasa da lanƙwasa rage ƙima a Hoto na 8, yana tabbatar da dogon rai da ingantaccen fitar haske.

5. Ƙirar Gani:Faɗin kusurwar haske na digiri 110 na iya isa ga aikace-aikacen ƙwalwa mai yawan shugabanci. Za a yi amfani da murfin mai watsawa don haɗa tushen maki da yawa zuwa cikin haske mai daidaito.

10. Ka'idojin Fasaha da Trends

10.1 Ka'idar Aiki

Wannan LED farin ne da aka canza phosphor. Babban abin semiconductor shine diode InGaN (Indium Gallium Nitride) mai fitar da hasken shuɗi. Wani ɓangare na hasken shuɗi yana sha ta hanyar murfin phosphor na yttrium aluminum garnet (YAG:Ce) mai cike da cerium, wanda ke sake fitar da shi azaman hasken rawaya mai faɗi. Haɗuwar sauran hasken shuɗi da canza hasken rawaya yana haifar da fahimtar farin haske. Ma'auni na shuɗi zuwa hasken rawaya, wanda aka sarrafa ta hanyar abun da ke ciki da kauri na phosphor, yana ƙayyade Yanayin Zafin Launi (CCT).

10.2 Trends na Masana'antu

Sashin LED na tsaka-tsaki yana ci gaba da haɓakawa zuwa inganci mafi girma (lm/W) da ingantaccen aminci a maki masu fa'ida. Karɓar EMC da sauran kayan fakitin aiki masu inganci (kamar yumbu da thermoplastics) babban al'ada ne don ba da damar manyan igiyoyin tuƙi da ingantaccen kiyaye lumen. Hakanan akwai ci gaba da turawa don ƙimar Ma'auni na Nuna Launi (CRI) mafi girma da mafi daidaitaccen daidaiton launi (ƙwaƙƙwaran binning) don biyan buƙatun kasuwannin haske masu kula da inganci. Bugu da ƙari, haɗa waɗannan LED ɗin a kan allunan da aka daidaita kamar COBs (Chip-on-Board) ko igiyoyi masu sassauƙa al'ada ce ta aikace-aikace don sauƙaƙe taro da ingantaccen aikin zafi.
