10. Tambayoyin da ake yawan yi (Bisa ga Sigogi na Fasaha)

Q1: Menene bambanci tsakanin Tsayin Rana (634nm) da Babban Tsayin Rana (624nm)?

A1: Tsayin raƙuman ruwa shine tsayin raƙuman ruwa guda ɗaya a mafi girman matsayi na bakan fitarwa. Babban tsayin raƙuman ruwa an samo shi ne daga kimiyyar launi (zane na CIE) kuma yana wakiltar launin da ake gani a matsayin tsayin raƙuman ruwa guda ɗaya. Ga wannan LED ja, babban tsayin raƙuman ruwa na 624nm shine mabuɗin sigogi don ƙayyadaddun launi a aikace-aikace.

Q2: Shin zan iya tuƙi wannan LED a 50mA ci gaba?

A2: Ee, amma kawai idan yanayin yanayi ya kasance 45°C ko ƙasa. A manyan yanayin yanayi, dole ne a rage halin yanzu bisa ga ka'idar 0.75 mA/°C don hana yin zafi da haɓaka lalacewa.

Q3: Me yasa resistor na jere ya zama dole ko da ga tuƙi mai ƙarfin wutar lantarki akai-akai?

A3: Ƙarfin wutar lantarki na gaba (V_F) na LED yana da kewayon jurewa (1.8-2.4V). Haɗa LED da yawa a layi daya kai tsaye zuwa tushen ƙarfin wutar lantarki zai sa LED masu ƙananan V_Fsu jawo halin yanzu da yawa, wanda zai haifar da rashin daidaiton haske da yuwuwar gazawa.

11. Nazarin Shari'ar Ƙira da Amfani

Yanayi: Ƙirar Alamar Saƙon Hanyoyi ta Waje mai Bayyane.

Bukatu:Dole ne alamar ta kasance a bayyane a cikin hasken rana kai tsaye a nisan mita 100. Za ta yi amfani da jeri mai yawa na pixels ja. Yanayin aiki ya bambanta daga -20°C zuwa +60°C. Dole ne ƙirar ta tabbatar da daidaiton haske da dogon lokacin dogaro.

Zaɓuɓɓukan Ƙira tare da LTLMH4 EV7DA:

1. Zaɓin Bangaren:Matsakaicin ƙarfin haske mai yawa (4200 mcd) ya cika buƙatun karantawa na hasken rana. Fakitin mai jure danshi/UV yana da mahimmanci don amfani da waje.
2. Da'irar Tuƙi:An shirya LED a cikin matrix. Kowane ginshiƙi ana tuƙa shi ta hanyar tushen halin yanzu akai-akai. A cikin ginshiƙi, LED suna haɗuwa a jere don tabbatar da halin yanzu iri ɗaya, tare da kawar da buƙatar k_Fdrops plus headroom for the current regulator.
3. Thermal Management:Given the high ambient temperature possibility (up to 60°C), the drive current is derated. Using the max rating of 50mA at 45°C and derating 0.75mA/°C, the max current at 60°C is 38.75mA. A conservative design sets the operating current at 30mA. The PCB is designed with a large thermal ground plane connected to all LED P3 pads. Thermal vias under this plane transfer heat to the rear of the board, which is attached to the sign's aluminum chassis acting as a heat sink.
4. Binning for Consistency:To ensure a uniform appearance, LEDs from a single luminous intensity bin (e.g., EU or EV) and a single forward voltage bin (e.g., 2A) are specified for the entire production run, minimizing pixel-to-pixel variation.
5. Manufacturing Process:The MSL3 rating is communicated to the contract manufacturer. They follow the prescribed baking procedures if floor life is exceeded and adhere strictly to the 260°C peak reflow profile to prevent package damage.

This case demonstrates how the detailed parameters in the datasheet directly inform critical design decisions for a reliable and high-performance end product.
