Gịnị bụ uru nke LED ngosi nchapụta?Dị ka a na-ajụ mgbasa ozi, Ikanam ngosi meziri ugboro ugboro na-egosi na ndụ anyị, na ina maka mmezi njirimara ozi ikwu Ikanam ngosi meziri nwekwara ụba.Ka anyị tụlee otu esi amata nchapụta nke ihe ngosi LED.
Nke mbụ, ka anyị ghọta ihe bụ nchapụta nke ihe ngosi LED:
Nchapụta nke tube na-ebunye ọkụ LED na-ezo aka n'ịdị ike nke ìhè ahụ na-enwupụta, nke a na-akpọ ike ọkụ, nke a kọwara na MCD.Ngosipụta na-egbuke egbuke nke ihe ngosi LED bụ ndepụta zuru oke, nke na-ezo aka na ntinye aka zuru oke nke mkpokọta ọkụ ọkụ (luminous flux) nke modul LED niile n'otu olu na ìhè n'ebe dị anya.
Ngosipụta ọkụ LED: N'ime ntụzịaka enyere, ike na-enwu n'otu mpaghara otu.Akụkụ nke nchapụta bụ cd/m2.
Nchapụta dị nhata na ọnụọgụ LEDs kwa mpaghara otu yana nchapụta nke LED n'onwe ya.The ihie nke ihe LED bụ kpọmkwem proportionally na ya mbanye ugbu a, ma ya ndụ bụ inversely hà nhata na square nke ugbu a, ya mere mbanye ugbu a enweghị ike gabiga ókè n'ịchụso ihie.N'otu oge njupụta, nchapụta nke ihe ngosi LED dabere na ihe onwunwe, nkwakọ ngwaahịa na nha nke mgbawa LED ejiri.Nnukwu mgbawa ahụ, na-egbuke egbuke dị elu;N'aka nke ọzọ, na-ebelata nchapụta ahụ.
Yabụ kedu ihe nchapụta chọrọ nke nchapụta ambient maka ihuenyo ahụ?
Ihe achọrọ nchapụta izugbe bụ nke a:
(1) Ngosipụta ọkụ ime ụlọ:> 800CD/M2
(2) Ngosipụta LED nke ime ime ụlọ:> 2000CD/M2
(3) Ngosipụta LED n'èzí (nọdụ ala na ndịda na chere ihu n'ebe ugwu):> 4000CD/M2
(4) Ngosipụta LED n'èzí (nọdụ ala n'ebe ugwu na ihu ndịda):> 8000CD/M2
Ogo nke tubes na-egbuke egbuke LED nke a na-ere n'ahịa adịghị mma, na ọtụtụ n'ime nchapụta ahụ enweghị ike ijide n'aka.A na-aghọgbu ndị na-eri ihe site na ihe omume nke shoddy.Ọtụtụ ndị mmadụ enweghị ike ịmata ọdịiche dị na nchapụta nke tubes ọkụ ọkụ.Ya mere, ndị ahịa na-ekwu na ihe na-egbuke egbuke bụ otu ihe ahụ na-egbuke egbuke.Ma o siri ike ịmata ya site na anya gba ọtọ, yabụ kedu ka esi amata ya?
1. Otu esi amata nchapụta nke ihe ngosi LED
1. Mee ka ọkụ eletrik 3V DC dị mfe iji jikọọ na diode na-enye ọkụ n'onwe gị.Ọ kacha mma iji batrị mee ya.Ị nwere ike iji batrị bọtịnụ abụọ, tinye ha na obere akpa rọba ma wepụta nyocha abụọ dị ka ihe dị mma na nke na-adịghị mma.A na-eme njedebe ọdụ ozugbo ka ọ bụrụ ngbanwe na shrapnel.Mgbe a na-eji ya eme ihe, nyocha dị mma na nke na-adịghị mma kwekọrọ na kọntaktị dị mma na nke na-adịghị mma nke diode na-enye ìhè.Na ntụtụ na-adịghị mma, pịa ma jide ngbanwe na njedebe, na tube na-egbuke egbuke ga-amụnye ọkụ.
2. Nke abuo, jikọta fotoresistor na multimeter dijitalụ iji mepụta ngwaọrụ nha ọkụ dị mfe.Jiri waya abụọ dị mkpa duzie fotoresistor wee jikọọ ha ozugbo na pensụl abụọ nke multimeter dijitalụ.A na-etinye multimeter na ọnọdụ 20K (dabere na fotoresistor, Gbalịa mee ka ọgụgụ ahụ bụrụ nke ziri ezi dịka o kwere mee).Mara na uru a tụrụ bụ n'ezie uru nguzogide nke fotoresistor.Ya mere, ka ìhè ahụ na-egbuke egbuke, ọnụ ahịa dị ntakịrị.
3. Were diode ọkụ na-enye ọkụ LED ma jiri 3V ugbu a dị n'elu na-enwu ọkụ.Isi nke na-enwu ọkụ na-eche ihu ma dị nso n'elu foto na-emetụ n'ahụ nke fotoresistor ejikọrọ.N'oge a, multimeter na-agụ iji mata ọdịiche dị na ìhè nke LED.
2. Ọkwa ịkpa oke nchapụta na-ezo aka n'ọkwa nchapụta nke onyonyo nke anya mmadụ nwere ike ịmata site na nke gbara ọchịchịrị ruo na nke kachasị ọcha.
Ọkwa isi awọ nke ihuenyo ngosi LED dị oke elu, nke nwere ike iru 256 ma ọ bụ ọbụna 1024. Otú ọ dị, n'ihi ntakịrị mmetụta nke anya mmadụ na-egbuke egbuke, a pụghị ịmata ọkwa ndị a n'ụzọ zuru ezu.N'ikwu ya n'ụzọ ọzọ, ọ ga-ekwe omume na ọtụtụ anya mmadụ dị n'akụkụ ọnụ ọgụgụ isi awọ yiri otu.Ọzọkwa, ikike ịmata ọdịiche nke anya dịgasị iche site na mmadụ gaa na onye.Maka ihuenyo ngosi LED, ọkwa dị elu nke njirimara anya mmadụ, nke ka mma, n'ihi na ihe oyiyi ahụ gosipụtara bụ maka ndị mmadụ ịhụ mgbe niile.Ọkwa nchapụta ka anya mmadụ nwere ike ịmata, ka oghere agba nke ihe ngosi LED na-abawanye, ma nwee ike igosipụta agba bara ụba.Enwere ike iji ngwanrọ pụrụ iche nwalee ọkwa ịkpa oke nchapụta.N'ozuzu, ihuenyo ngosi nwere ike iru ọkwa 20 ma ọ bụ karịa, ọbụlagodi na ọ bụ ọkwa dị mma.
3. Ihe achọrọ maka nchapụta na akụkụ nlele:
Icha ọkụ nke ime ụlọ LED ngosi ga-adị n'elu 800cd / m2, na nchapụta nke n'èzí zuru-agba ngosi ga-adị n'elu 1500cd / m2 iji hụ na ọrụ nkịtị nke LED ngosi, ma ọ bụghị na-egosipụta image agaghị doro anya n'ihi na nchapụta dị oke ala.The ihie na-tumadi kpebisiri ike site àgwà nke LED anwụ.The size nke ikiri n'akuku kpọmkwem na-ekpebi ndị na-ege ntị nke LED ngosi, otú ibu ka mma.A na-ekpebi akụkụ nlele ahụ site na ngwugwu anwụ.
