Iingcebiso zokuThenga izibane ze-LED zokuqhushumba-ubungqina

Imarike izaliswe ziindidi ezahlukeneyo zezibane ze-LED ezibonisa ukuqhuma, nganye ineenkcukacha ezahlukeneyo ezivela kubenzi abahlukeneyo. Ngoko, umntu ukhetha njani kolu luhlu lubanzi lweemveliso? Njengoko kukho iibenchmarks ezithile zokuvavanya ukusebenza kwezibane ze-LED, Nasi isikhokelo esikhethekileyo sokuncedisa kwinkqubo yokuthengwa kwempahla kunye nokunceda ukuphepha ilahleko kwiiprojekthi zokukhanyisa ngenxa yokukhangela okungafanelekanga.

1. Isalathiso sokuBonelela ngombala (CRI):

Ngaphambi kokuthenga, kubalulekile ukujonga iinkcukacha zemveliso okanye ubuze ummeli wentengiso malunga ne-CRI. Ngokubanzi, Izibane ze-LED kunye ne-CRI phakathi kwe-RA80 kunye 100 bonisa ukusebenza kakuhle kombala; abo baphakathi kweRA50 kunye 79 ube nomsebenzi ophakathi wombala, ngelixa izibane ezine-CRI engaphantsi kwe-Ra50 zinonikezelo olubi lombala. Ngoko ke, kuyacetyiswa ukuba ukhethe izibane ze-LED ezine-CRI ephezulu.

2. Kuphephe ukuKhanya:

Ilitha lichaphazela kakhulu umgangatho wokukhanya kwaye kufuneka lincitshiswe. Khetha izibane ezingavelisi ilitha. Ngokufanelekileyo, khetha izinto ezilungiselelweyo ezineziphazamisi ezineqabaka ezikhupha into ethambileyo, ukukhanya.

3. ULungelo oluLungileyo oluLungileyo lweziLungiso zokuKhanya kwe-LED:

I “ukusebenza kakuhle okukhanyayo” yesibane esigqityiweyo se-LED sisibane esikhanyayo esikhutshwayo nge-LED phantsi kombane olinganisiweyo owahlulwe ngamandla ewonke asetyenzisiweyo, kulinganiswa ngeelumens ngewathi nganye (lm/W). Iphezulu eli xabiso, ngcono impembelelo yokonga amandla, kunye nombane omncinci osetyenziswayo. Ngoko ke, khetha izibane ze-LED ezine-lumens eziphezulu nge-watt nganye (ngokukhethekileyo inkulu kune 80 lm/W; njengokuba, izixhobo kunye nokusebenza kakuhle kwe-≥85 lm/W lukhetho olulungileyo).

4. Ukunyuka kobushushu be-LED:

Ngokuqhelekileyo, okuvumelekileyo ubushushu ukunyuka kwezibane ze-LED ezisetyenziswayo kuphakathi kwe-25℃ ukuya kwi-30℃. Ngokuthe ngqo, iqondo lobushushu kwi-heatsink ye-LED bubushushu obuphakathi kunye nokunyuka kobushushu obuvumelekileyo. Oko ikukuthi, ukuba ubushushu be-ambient yi-37℃, iqondo lobushushu kwi-heatsink ye-LED kufuneka libe yi-67℃ (37℃+30℃). Ukuba ingaphezulu koku, ukunyuka kweqondo lokushisa kuthathwa njengokungahambelani. Ubushushu lutshaba lwentsebenzo ye-LED; ubushushu obuncinci obuveliswayo, Ukuphakama kokukhanya okukhanyayo kokukhanya kwe-LED. Ukongeza, ukunyuka ngokukhawuleza kweqondo lobushushu kwi-heatsink kubonisa ukuhanjiswa okuphezulu kwe-thermal kunye nokumelana okuphantsi kwe-thermal yesibane sokukhanyisa i-LED..

5. Ubomi be-LED:

Ukukhanya okukhanyayo kokuqala kokukhanya okutsha kuku 100%. Ixesha elidlulele, ukusebenza kakuhle kokukhanya kuya kuncipha. Ubomi be-LED lixesha elithathayo ukuguquguquka kwayo okukhanyayo ukunciphisa 70% yokuguquguquka kokuqala. Ngokwemvelo, ixesha elide ngcono. Njengokuba, Ii-LED ezivela kwiimpawu ezithembekileyo zinokuhlala ixesha elide 30,000 iiyure, elungele ngokukodwa iiprojekthi ezinkulu zokukhanyisa.

Ezi zingcebiso zokukhetha izibane ze-LED ezingenakudubula. Ngethemba, esi sikhokelo siya kukunceda ekwenzeni izigqibo ezizizo.
