Nezve marambi emotokari, isu tinowanzo teerera kune huwandu hwema lumens uye simba. Zvinowanzotendwa kuti iyo yakakwirira iyo "lumen kukosha", iyo inopenya mwenje! Asi kune mwenje we LED, haugone kungoreva kukosha kwe lumen. Iyo inodaidzwa kuti lumen inhengo yemuviri inotsanangura iyo inopenya flux, iyo inotsanangurwa nefizikisi sekenduru (cd, candela, luminous intensity unit, yakaenzana nekupenya kwekupenya kwekenduru yakajairwa), mukona yakasimba (chikamu. denderedzwa rine radius yemamita 1). Pa sphere, kona inomiririrwa ne spherical cone inoenderana ne spherical korona ye 1 square metre, iyo inoenderana nepakati pekona yepakati-chikamu (inenge 65 °), inoburitsa iyo yakazara emitted luminous flux.
Kuti tive neruzivo rwakanyanya, isu tichashandisa iyo LED tochi kuita kuyedza kuri nyore. Tochi iri padyo nehupenyu uye inogona kunyanya kuratidza dambudziko racho.
Kubva pamifananidzo mina iri pamusoro, tinogona kuona kuti tochi imwe chete ine chitubu chechiedza chakafanana, asi chiratidziro chakavharwa, saka pane musiyano mukuru, unoratidza kuti kupenya kwetochi hakusi kungoenderana nekupenya kwechiedza. mwenje sosi pachayo, asi zvakare haiparadzaniswe kubva kune reflector. Hukama. Nokudaro, kupenya kwemwenje wepamusoro hakugoni kuongororwa chete ne lumens. Kune mwenje wepamberi, isu tinofanirwa kushandisa zvinonyanya kuitika "light intensity" kutonga,
Kusimba kwechiedza kunoreva simba rechiedza chinooneka chinogashirwa panzvimbo yeyuniti, inonzi illuminance, uye unit iLux (Lux kana Lx). Izwi remuviri rinoshandiswa kuratidza kusimba kwechiedza uye kuwanda kwechiedza pamusoro penzvimbo yechinhu.
Iyo yekuyera nzira yekuvhenekera zvakare iri nyore uye isina kuchena. Mushure mekutakura, inogona kuyerwa chete neilluminometer. Iyo lumens inogona kungoratidza iyo data yemwenje pachayo mota isati yaiswa. Chiedza mushure memotokari inoda kuiswa mukati uye kudzorwa neanoratidzira. Kana iyo yakatarisa isina kunaka, kana chiedza chisingagoni kubviswa zvakakwana, pasinei nokuti yakakwirira sei "lumen" haina pfungwa.

Magetsi emota anodawo kuburitsa mwenje kuburikidza nemwenje sosi uye obva adzorwa nereflector cup. Musiyano kubva kune tochi ndewekuti chivara chemwenje chemotokari hachina denderedzwa senge tochi. Zvinodiwa zvemarambi emotokari zvakaomarara uye zvakaoma, zvekuchengetedza kutyaira uye Tichifunga nezve kuchengetedzwa kwevanofamba netsoka, chiyero chakatemerwa kona uye huwandu hwechiedza, uye chiyero ichi chinonzi "chiedza cherudzi".
Iyo "chiedza chemhando" (yakaderera danda) yemwenje yemusoro inofanirwa kuve yakaderera kuruboshwe uye kumusoro kurudyi, nekuti kuruboshwe rwemotokari dzepamba ndiyo nzvimbo yemutyairi. Kuti udzivise mwenje unopenya uye uvandudze kuchengetedzwa kwekutyaira apo mota mbiri idzi dzinosangana panguva yekutyaira husiku. Chiedza chekurudyi chakakwirira. Kumutyairi wemotokari yeruboshwe, rutivi rworudyi rwemotokari rine mutsara wakashata wekuona uye rinoda nzvimbo yakafara yekuona. Edza kukwanisa kuvhenekera nzira, mharadzano uye mamwe mamiriro emugwagwa ane nzvimbo yakakura kurudyi, kana zvichibvira. Ita chiito pachine nguva. (Kana iri yerudyi dhiraivha mota, iyo mwenje patani yakatarisana)
Zvakanakira mwenje we LED
1. Zvigadzirwa zvemwenje zve LED zvakaderera-voltage kutanga, uye kuchengetedza chinhu chakanyanya kukwirira;
2. Zvigadzirwa zvemwenje zve LED zvinotanga pakarepo, izvo zvinonyanya kuenderana nezvinodiwa nemotokari dzevanhu;
3. Kuchengetedza magetsi uye kuchengetedzwa kwezvakatipoteredza, nezvakanaka zviri pachena zvekugadzirwa kwemotokari itsva dzemagetsi mune ramangwana;
4. Nekuenderera mberi kwekugadzirisa uye kuvandudza kwepamusoro-simba re LED rambi bead industry chain, iyo inodhura-inoshanda mukana wemwenje we LED ichawedzera kuratidzwa.
5. Ipurasitiki ye LED chiedza sosi yakasimba, iyo yakanyatsokodzera kune ramangwana remunhu maitiro ekushandisa.
