Don haka, dole ne a gwada su don jujjuwar wutar lantarki na gaba da na gaba a wurin aiki, da kuma sigogi kamar jujjuyawar wutar lantarki da juyar da wutar lantarki.
2. Haske mai haske da hasken haske na farin LED
Jimlar makamashin lantarki da farin LED ke fitarwa a cikin raka'a na lokaci ana kiransa radiant flux, wanda shine ikon gani (W). Ga farin tushen hasken LED don haskakawa, abin da ya fi damuwa shi ne tasirin gani na haske, wato, adadin hasken da ke fitowa daga hasken da zai iya sa idon ɗan adam ya gane, wanda ake kira luminous flux. Matsakaicin jujjuyawar haske zuwa wutar lantarki na na'urar tana wakiltar ingancin hasken farin LED.
3. Hasken ƙarfin rarraba haske na farin LED
Ana amfani da madaidaicin rarraba hasken haske don nuna rarraba hasken da LED ke fitarwa a duk sassan sararin samaniya. A cikin aikace-aikacen hasken wuta, rarraba hasken haske shine mafi mahimmancin bayanai lokacin ƙididdige daidaituwar hasken haske na saman aiki da tsarin sararin samaniya na LEDs. Don LED wanda keɓaɓɓen katakon sararin samaniya yana jujjuyawa, ana iya wakilta shi da lanƙwan jirgin saman axis; don LED tare da katako na elliptical, ana amfani da lanƙwasa na jiragen sama guda biyu na tsaye na katako na katako da kuma elliptical axis. Don wakiltar hadadden siffa mai asymmetrical, gabaɗaya ana wakilta shi da lanƙwan jirgin sama sama da 6 na axis.
4, da spectral ikon rarraba farin LED
Rarraba ikon gani na farin LED yana wakiltar aikin ƙarfin haske a matsayin aikin tsayin raƙuman ruwa. Yana ƙayyade duka launi na luminescence da haskensa mai haske da fihirisar ma'anar launi. Gabaɗaya, dangi na rarraba wutar lantarki yana wakiltar rubutun S(λ). Lokacin da ƙarfin baƙon ya faɗi zuwa 50% na ƙimar sa tare da bangarorin biyu na kololuwar, bambanci tsakanin tsayin raƙuman ruwa biyu (Δλ = λ2-λ1) shine band na gani.
5, zafin launi da ma'anar ma'anar launi na farin LED
Don tushen haske kamar farin LED wanda ke fitar da cikakken farin haske, daidaitawar chromaticity na iya bayyana ainihin launi na tushen hasken, amma takamaiman ƙimar yana da wahala a haɗa shi da tsinkayen launi na al'ada. Sau da yawa mutane suna kiran launin orange-ja mai haske a matsayin "launi mai dumi", kuma mafi zafi ko launin shuɗi mai launin shuɗi ana kiransa "launi mai sanyi". Don haka, yana da hankali don amfani da zafin launi don nuna launin haske na tushen haske.
7, thermal yi na farin LED
Haɓaka ingancin haske na LED da ƙarfi don hasken wuta yana ɗaya daga cikin mahimman batutuwan ci gaban masana'antar LED a halin yanzu. A lokaci guda, zafin haɗin PN na LED da matsalar ɓarkewar zafi na gidaje suna da mahimmanci musamman, kuma ana bayyana su gabaɗaya ta sigogi kamar juriya na thermal, yanayin yanayin yanayin, da zafin haɗuwa.
8, aminci na radiation na farin LED
A halin yanzu, Hukumar Kula da Kayan Wutar Lantarki ta Duniya (IEC) tana daidaita samfuran LED tare da buƙatun lasers na semiconductor don gwajin amincin radiation da nunawa. Saboda LED ƙunƙuntaccen katako ne, na'ura mai haske mai haske, la'akari da haskensa zai iya zama cutarwa ga kwayar idon mutum, ƙa'idar kasa da kasa ta ƙayyade iyaka da hanyoyin gwaji don ingantaccen radiation ga LEDs da ake amfani da su a lokuta daban-daban. A halin yanzu ana aiwatar da amincin hasken rana don haskaka samfuran LED azaman buƙatun aminci na tilas a cikin Tarayyar Turai da Amurka.
9, AMINCI da rayuwar farin LED
Ana amfani da ma'aunin abin dogaro don auna ƙarfin LEDs don yin aiki da kyau a wurare daban-daban. Rayuwa shine ma'auni na rayuwa mai amfani na samfurin LED kuma yawanci ana bayyana shi ta hanyar rayuwa mai amfani ko ƙarshen rayuwa. A cikin aikace-aikacen hasken wuta, rayuwa mai tasiri shine lokacin da ake ɗauka don LED ɗin ya lalace zuwa kashi na ƙimar farko (ƙimar da aka tsara) a ƙimar ƙima.
(1) Matsakaicin rayuwa: Lokacin da aka ɗauka don batch na LED don haskakawa a lokaci guda, lokacin da adadin LEDs marasa haske ya kai 50% bayan wani lokaci.
(2) Rayuwar Tattalin Arziki: Lokacin da aka yi la'akari da lalacewar LED da attenuation na fitowar haske, an rage yawan fitowar da aka haɗa zuwa wani lokaci, wanda shine 70% don hasken haske na waje da 80% don hasken cikin gida.
