Yakazara-yakazara tekinoroji ye LED yave buzzword mumakore achangopfuura, kunyanya kana zvasvika pakutevedzera mwenje wezuva nekuvandudza kunaka kwechiedza. Muchikamu chino, tichanyura munyika ye-full-spectrum LEDs, kuti dzakauya sei, dzakagadzirwa sei, uye kuti dzinoshandiswa kupi. Isu tichataura nezve maitiro aungaita azere-spectrum maLED ane akasiyana chip uye phosphor musanganiswa, matambudziko ekuagadzira, uye maitiro avari kuratidza muzvigadzirwa zvakaita semarambi etafura, mwenje wemaindasitiri, uye kunyange zviedza zvekukura kwezvirimwa. Pakupedzisira, tichapindura mubvunzo, "Unonyatsoda mwenje we-full-spectrum?" uye “Ungadaro sei full-spectrum lighting zvinokubatsira here munharaunda yako?"
Tsanangudzo ye "Full-Spectrum" LEDs
Kana tichitaura nezve “full-spectrum” maLED nhasi, zvakakosha kujekesa kuti “full-spectrum” zvinorevei. Chokwadi "full-spectrum" inoreva chiedza chinobudiswa kubva kunzvimbo inovhara spectrum yose kubva kuultraviolet (UV), chiedza chinooneka, kusvika kune infrared (IR), ichitevedzera kuzere kwechiedza chezuva (sezvinoratidzwa mumufananidzo 1).
Iyi ndiyo "full-spectrum" yakazara inowanikwa muzvisikwa. Zvisinei, iyo "full-spectrum" LED iyo vanhu vakawanda vanotaura nezvayo nhasi itsanangudzo yakamanikana. Muchirevo che LED, "full-spectrum" inoreva chiedza chinobudiswa mukati mechiedza chinooneka chinoda kufanana nechiedza chezuva mumutsara iwoyo (sezvinoratidzwa mumufananidzo 2).
Iyo ultraviolet uye infrared zvikamu hazvibatanidzwe, kunyanya kuita yakazara-spectrum ma LEDs akwanise kugadzirwa kwemazhinji. Kuwedzera UV uye IR kwaizoomesa iyo yese yekurongedza sisitimu uye mashandisiro, zvichiita kugadzirwa kwakakura uye kushandiswa kunoshanda kunenge kusingaite. Kunyangwe paine chete inooneka spectrum inosanganisirwa, hazvisi nyore kuwana yakazara-spectrum LEDs. Somuenzaniso, kuwana yakakwirira color rendering index (CRI) pedyo nezana, makambani mazhinji anonetsekana kuvandudza CRI kubva pa100 kusvika pa96, ndoda kuwana makumi mapfumbamwe nemapfumbamwe kana kupfuura.

Maitiro Ekuwana Yakazara-Spectrum LEDs
Mune dzidziso, kune nzira mbiri huru dzekuwana yakazara-spectrum LEDs: imwe ndeye kushandisa machipisi uye imwe yacho nekushandisa phosphors. Padivi re chip, kune nzira mbiri huru: imwe ndeye chip inonakidza phosphor, uye imwe iri kushandisa chip yega isina phosphor. Padivi rephosphor, unofanirwa kubatanidza phosphors nechip, uye iwe unofanirwa kusarudza akasiyana emission uye excitation wavelengths yemusanganiswa. Pakazara, kune nzira ina huru dzekuwana yakazara-spectrum LEDs:
1. Single-band Blue Chip Inonakidza Phosphors
Iyi nzira yakafanana neyakajairwa kurongedza kwe LED, asi akawanda phosphors anowedzerwa (semuenzaniso, girini, yero, tsvuku, kana kunyange orenji, cyan, bhuruu). Kunyangwe izvi zvichigona kuburitsa mwenje padyo ne-full-spectrum, pachine yakakurumbira yebhuruu mwenje peak. Uyezve, kushanda zvakanaka kwephosphors senge cyan nebhuruu kwakadzikira, uye mwenje mu470-510nm renji inogona kunge isipo.
2. Dual-band kana Triple-band Blue Chip Inofadza Phosphors
Iyi nzira inonatsiridza pane imwe-bhendi maitiro nekushandisa mbiri-bhendi kana katatu-bhendi yebhuruu chip kufadza phosphors mhiri kwakasiyana wavelengths. Iwo maviri-bhendi machipisi anowanzo shandisa mativi maviri: 430-450nm uye 460-480nm, nepo matatu-bhendi machipi anoshandisa matatu: 430-440nm, 440-460nm, uye 460-480nm. Izvi zvinobvumira kuchinjika kwakawanda mukubatanidza machipisi nephosphors kuti ienderane zvirinani nechiedza chezuva (sezvinoratidzwa mumufananidzo 3). Nenzira iyi, CRI inogona kudarika 98. Zvisinei, nzira iyi inoda zvakasiyana-siyana zvephosphors, zvichiita kuti zvive zvakaoma kuvimbisa kuwirirana uye kugadzikana panguva yekugadzirwa kwehuwandu.

3. UV Chip Inonakidza Phosphors
Iyi nzira ine chiedza chakaderera. Chikonzero chikuru ndechekuti maphosphors mazhinji anotengeswa akagadzirirwa kushanda nemachipisi ebhuruu, kwete machipisi eUV, saka kugona kwavo kwekunakidzwa kwakadzikira mumhando yeUV. Pamusoro pezvo, machipisi eUV anowanzo kubva pa385-405nm, ayo zvakare ane kushomeka kwekuita. Kunyangwe machipisi eUV achinyatso kutevedzera mwenje wezuva uye kudzivirira kuvepo kwepfupi-wavelength yebhuruu mwenje (sezvinoratidzwa muMufananidzo 4), iyi nzira ine zvinokanganisa. Semuenzaniso, machipisi eUV anokonzera kuderera kwakanyanya kwephosphors nekufamba kwenguva, zvichikonzera kushanduka kwemavara uye nyaya dzekushisa kwemavara. UV mwenje unokuvadzawo organic zvinhu senge encapsulants, kuderedza iyo Hupenyu hwe LED.

4. Multi-chip Combination Method
Iyi nzira inosanganisa machipisi anoburitsa bhuruu, cyan, girinhi, yero, uye dzvuku mwenje kuti uwane yakazara spectrum. Kunyange izvi zvichigona kushanda mudzidziso, hazvinyanyi kushandiswa nekuda kwematambudziko akati wandei. Kune imwe, machipisi anoburitsa mwenje ane nhete bandwidths, zvichiita kuti zviome kuwana yakafara spectrum iyo phosphors inopa. Pamusoro pezvo, kushanda kweakasiyana mavara machipisi kunosiyana zvakanyanya, zvichiita kuti zviome kuenzanisa kubuda kwechiedza. Nekufamba kwenguva, kushanduka kwemavara uye tembiricha shanduko inogonawo kuitika nekuda kwekusiyana kwekuderedzwa kwemachipisi.
Kupa kuenzanisa kwakajeka, tafura inotevera inopfupisa nzira ina dzekuwana yakazara-spectrum LEDs:

Zvishandiso zveFull-Spectrum LEDs
Zvino zvatavhara nzira dzekuwana azere-spectrum maLED, tingaashandisa sei nemazvo? Imwe pfungwa huru ndeye tembiricha yemavara. Chiedza chezuva chinoshanduka zuva rose uye mumwaka. Somuenzaniso, the kupisa kwemavara pakubuda kwezuva inenge 2000K, masikati inenge 5000K, uye pakuvira kwezuva inenge 2300K. Naizvozvo, ma LED akazara-akazara anofanirwa kugadzirwa kuti atevedzere inoenderana nechiedza chezuva pane akasiyana mavara tembiricha, ayo anogona kuwanikwa uchishandisa nzira dzakatsanangurwa pamusoro.
Kubva pane tsananguro iri pamusoro, ma-full-spectrum ma LED anogona kushandiswa mune chero akajairwa mwenje mwenje, senge mwenje wemba, kunze kwechiedza, mwenje weindasitiri, marambi etafura, full spectrum led mitsetse uye kunyange mwenje wezvirimwa. Mashandisirwo chaiwo anoenderana zvakanyanya nemutengo uye kugamuchirwa kwevatengi. Parizvino, marambi edhesiki ndiwo anonyanya kushandiswa, anowanzo kutengeswa sechiedza chakaderera-bhuruu, kudzivirira maziso, uye ruvara-tembiricha inogadziriswa. Mwenje iyi ine mutengo wakakwirira kudarika marambi akajairwa. Kuenzanisa pakati peChinese yenyika zviyero uye "full-spectrum certification" zvinodiwa zveCRI zvinoratidzwa muTebhu 2. Sezvinoonekwa patafura, chiyero chenyika cheChinese chemarambi edeski chinogona kusangana nyore neakajairwa magetsi e LED, nepo yakazara-spectrum. certification inoda kushanda kwepamusoro.
