Ngosipụta LED bụ ngwaọrụ na-eji diodes na-enye ọkụ (LEDs) dị ka ihe na-enye ọkụ iji gosipụta eserese, vidiyo, ihe ngosi na ozi ndị ọzọ site na ihuenyo eletrọnịkị. Ngosipụta LED nwere uru nke nchapụta dị elu, obere ike oriri, ogologo ndụ ogologo oge, akụkụ nlele sara mbara, wdg, a na-ejikwa ya na mgbasa ozi ime ụlọ na n'èzí, njem, egwuregwu, ntụrụndụ omenala na ubi ndị ọzọ. Iji hụ na mmetụta ngosipụta na ike ịchekwa ike nke ihuenyo ngosi LED, ọ dị mkpa iji gbakọọ mpaghara ihuenyo na nchapụta nke ọma.
1. Usoro nke ịgbakọ mpaghara ihuenyo nke ihuenyo ngosi LED
Ebe ihuenyo nke ihe ngosi LED na-ezo aka n'ogo nke ebe ngosi ya dị irè, na-emekarị na mita mita. Iji gbakọọ mpaghara ihuenyo nke ihe ngosi LED, ọ dị mkpa ka amata paramita ndị a:
1. Ntụpọ ntụpọ: anya etiti n'etiti pikselụ ọ bụla na pikselụ dị n'akụkụ, na-abụkarị na millimita. Obere ntụpọ ntụpọ ahụ, ịdị elu pixel density dị elu, mkpebi ahụ dị elu, mmetụta ngosi na-edo anya karị, mana ọnụ ahịa dị elu. A na-ekpebi ntụpọ ntụpọ ahụ dabere na ọnọdụ ngwa n'ezie yana anya nlele.
2. Modul size: nke ọ bụla modul nwere ọtụtụ pikselụ, nke bụ isi unit nke LED ngosi. A na-ekpebi nha modul site na ọnụọgụ pikselụ kehoraizin na vetikal, na-adịkarị na centimita. Dịka ọmụmaatụ, modul P10 pụtara na modul ọ bụla nwere pikselụ 10 n'ahịrị na kwụ ọtọ, ya bụ, 32 × 16 = 512 pikselụ, na nha modul bụ 32 × 16 × 0.1 = 51.2 square centimeters.
3. Ihuenyo size: The dum LED ngosi na-sliced site ọtụtụ modul, na ya size kpebisiri ike site na ọnụ ọgụgụ nke kehoraizin na vetikal modul, na-emekarị na mita. Dịka ọmụmaatụ, ihuenyo zuru oke nke P10 nke nwere ogologo mita 5 na ịdị elu nke mita 3 pụtara na e nwere 50 / 0.32 = 156 modul na ntụziaka kwụ ọtọ na 30 / 0.16 = 187 modul na ntụgharị ihu.
2. Usoro nke ịgbakọ nchapụta nke ngosi LED
Icha ọkụ nke ihe ngosi LED na-ezo aka n'ịdị ike nke ọkụ ọ na-amụba n'okpuru ọnọdụ ụfọdụ, na-emekarị na candela kwa square mita (cd/m2). Nke dị elu na-egbuke egbuke, ọkụ na-esiwanye ike, na-eme ka ọdịiche dị elu, na ike mgbochi nnyonye anya. A na-ekpebi nchapụta ahụ dabere na gburugburu ngwa ngwa yana akụkụ nlele.
1. Ihe na-egbuke egbuke nke otu oriọna LED: ọkụ ọkụ na-esi na ọkụ ọkụ ọ bụla agba agba, na-emekarị na millicandela (mcd). A na-ekpebi ọkụ nke otu oriọna LED site na ihe onwunwe ya, usoro ya, ugbu a na ihe ndị ọzọ, na ìhè nke oriọna LED nke agba dị iche iche dịkwa iche. Dịka ọmụmaatụ, nchapụta nke ọkụ ọkụ na-acha uhie uhie na-abụkarị 800-1000mcd, nchapụta nke ọkụ ọkụ na-acha akwụkwọ ndụ akwụkwọ ndụ bụ 2000-3000mcd, na nchapụta nke ọkụ ọkụ na-acha anụnụ anụnụ bụ 300-500mcd.
2. Nchapụta nke pikselụ ọ bụla: pixel ọ bụla nwere ọtụtụ ọkụ LED nke agba dị iche iche, na ike ọkụ na-esi na ya pụta bụ nchikota nke nchapụta nke ọkụ ọkụ ọ bụla nke agba LED, na-abụkarị na candela (cd) dị ka unit. A na-ekpebi nchapụta nke pixel ọ bụla site na nhazi ya na nha ya, na nchapụta nke pixel ọ bụla nke ụdị ngosi LED dị iche iche. Dịka ọmụmaatụ, pikselụ ọ bụla nke ihuenyo zuru oke P16 nwere 2 red, 1 green, and 1 blue LED light. Ọ bụrụ na ejiri 800mcd red, 2300mcd green, na 350mcd acha anụnụ anụnụ LED ọkụ, nchapụta nke pixel ọ bụla bụ (800×2 +2300+350)=4250mcd=4.25cd.
3. The n'ozuzu ihie ihuenyo: ìhè ike emitted site dum LED ngosi bụ nchikota nke nchapụta nke niile pikselụ kewara site na ihuenyo ebe, na-emekarị na candela kwa square mita (cd / m2) dị ka unit. A na-ekpebi nchapụta ihuenyo n'ozuzu ya site na mkpebi ya, ọnọdụ nyocha, ịkwọ ụgbọala ugbu a na ihe ndị ọzọ. Ụdị ihuenyo ngosi LED dị iche iche nwere nchapụta n'ozuzu ya dị iche iche. Dịka ọmụmaatụ, mkpebi n'otu square nke ihuenyo zuru oke P16 bụ 3906 DOT, na usoro nyocha bụ nyocha 1/4, ya mere nchapụta kachasị elu ya bụ (4.25 × 3906/4) = 4138.625 cd/m2.
3. Nchịkọta
Isiokwu a na-ewebata usoro nke ịgbakọ mpaghara na nchapụta nke ihuenyo ngosi LED, ma nye usoro na ihe atụ kwekọrọ. Site na usoro ndị a, enwere ike ịhọrọ paramita ngosi ngosi LED kwesịrị ekwesị dabere na mkpa na ọnọdụ n'ezie, yana enwere ike ịkwalite mmetụta ngosipụta na nrụpụta ike. N'ezie, na ngwa ndị bara uru, ọ dị mkpa ka a tụlee ihe ndị ọzọ, dị ka mmetụta nke ìhè ambient, okpomọkụ na iru mmiri, ikpo ọkụ ọkụ, wdg na arụmọrụ na ndụ nke ngosi LED.
Ihe ngosi LED bụ kaadị azụmahịa mara mma na ọha mmadụ taa. Ọ nwere ike ọ bụghị naanị igosipụta ozi, kamakwa ibuga omenala, mepụta ikuku ma kwalite onyonyo. Otú ọ dị, iji nweta mmetụta kachasị elu nke ihe ngosi LED, ọ dị mkpa ịmara ụfọdụ ụzọ mgbako isi, nke ọma chepụta ma họrọ mpaghara ihuenyo na nchapụta. Naanị n'ụzọ dị otú a anyị nwere ike hụ na ngosipụta doro anya, nchekwa ike, nchebe gburugburu ebe obibi, ịdịte aka na akụ na ụba.
