Saddex daqiiqo si aad wax uga akhrido wax ku saabsan nalka LED-ka "farsamo-sare"

I: waa maxay LEDs?
Ilaha iftiinka ka dib dhaldhalaalka, nalalka fluorescent, habka horumarinta LED, LED wuxuu leeyahay isticmaalka tamarta hooseeya, dhalaalka sare, meerkuri-free aan sun ahayn, nolol dheer, bilawga degdega ah, balaastikada iyo faa'iidooyinka kale, ayaa bedelay ilaha iftiinka dhaqanka, Maqaalkani ma sameeyo wax badan oo ku saabsan isha iftiinka dhaqameed si dib loogu eego.

Waxa loogu yeero LED waa Light Emitting Diode soo gaabinta, taas oo ah, diode iftiin bixisa, waa qalab iftiin-bixiya semiconductor, marka labada daraf lagu daro koronta hore, sidayaal semiconductor ee xarunta ay sababtay qiiqa photon iyo soo saaro iftiin.LED waxay si toos ah u soo saari kartaa casaan, jaalle, buluug, cagaar, buluug, oranji, guduud, iftiin cad.

II: Qaab dhismeedka tusbaxyada iftiinka LED
1, Isha iftiinka LED by bracket, chip, xabagta, fosfoor, ka kooban silig
2, LED bracket guud ahaan waxaa laga sameeyaa naxaas (waxaa sidoo kale jira birta, aluminium iyo dhoobada, iwm), sababtoo ah conductivity copper waa mid aad u wanaagsan, waxay yeelan doontaa hogaanka gudaha, si ay ugu xidhaan electrodes gudaha kuul hogaanka.
3, silig il iftiin-dhamaadka sare waxaa loo isticmaalaa 0.999 silig dahab saafi ah, dhexroor ka badan: 0.8mil, 1.0mil.raacitaanka qaar ka mid ah soosaarayaasha qiimaha jaban ee leh silig daawaha naxaasta ah si ay u sameeyaan.
4, fosfooradu waa inay door ka ciyaarto hagaajinta heerkulka midabka isha iftiinka.
5, chips-dhamaadka sare ee caadiga ah waa: United States CREE (Core), Bridgelux (Bridgelux);Japan Nichia (Nichia), Jarmalka Osram Osram;Taiwan: Epistar.

III: Ilaha iftiinka LED-ka ee caadiga ah
Suuqa inta badan waxaa lagu faafiyaa moodooyinka LED-yada waa 2835, 5050, 5730, 5630, 3030, 4040, 7030 iyo COB isku dhafan iyo kuul awood sare leh, si loo kala saaro qaabka isha iftiinka waxaa lagu magacaabaa dhererka iyo ballaca SMD SMD, tusaale ahaan. , Jaantuska soo socda ee 2835 SMD, taas oo ah, ballaca 2.8 dheer 3.5, ilaha iftiinka noocan oo kale ah ayaa sida caadiga ah loo isticmaalaa nalalka LED-ka, nalalka iftiinka, nalalka, nalalka saqafka, xargaha iftiinka Ilaha iftiinka ayaa caadi ahaan loo isticmaalaa nalalka LED, nalalka hoose, nalalka iftiinka, nalalka saqafka, nalalka laydhka, tuubooyinka iyo wixii la mid ah.Awood kasta in ka badan qiyaastii 0.1W-1W.
Kuul quwad sare leh ayaa caadi ahaan loo isticmaalaa 1W, 2W, 3W midkiiba, oo caadi ahaan loo isticmaalo iftiinka iftiinka iyo iftiinka dibadda.
Ilaha iftiinka isku dhafan ee COB ayaa caadi ahaan loo isticmaalaa nalalka awooda sare leh sida iftiinka iftiinka, nalalka raadraaca iyo nalalka daadka, mid kastaa wuxuu leeyahay awood 5-50W.
