Vim li cas Luxeon imitation lumen siab zog LED nti tig dub?
Daim ntawv thov kev coj tus lumen LED tiag tiag xav tau qee yam hu ua tus tsav tsheb LED. Qhov no ntawm Circuit Court yog qhov paub tab heev thiab tsis muaj teeb meem kev lag luam. Yog li ntawd, kev ua lag luam rau LEDs yog qhov loj dua thiab loj dua ua ntej cov khoom siv tshiab thiab zoo dua tau tsim nyob rau hauv kev ua lag luam.

Imitation lumens coj qhia txog kev ceev faj rau kev siv LED teeb hlaws, yog vim li cas rau blackening ntawm lub teeb hlaws:
1. Carbonization
Cov khoom tsis xws luag ntawm rau qhov loj raw cov ntaub ntawv ntawm LED teeb hlaws dai (chips, brackets, bonding wires, phosphors, ntim kua nplaum) thiab cov txheej txheem tsis xws luag ntawm peb cov txheej txheem ntim loj (kev sib koom ua ke, kev sib txuas, kev sib txuas, thiab potting) tuaj yeem ua rau LED teeb hlaws dai. kub siab heev, ua rau ib nrab los yog tag nrho blackening ntawm LED teeb hlaws dai thiab carbonization ntawm lub teeb qhov chaw.
2. Oxidation
Silver yooj yim reacts nrog oxygen nyob rau hauv ib tug kub thiab high humidity ib puag ncig los tsim dub silver oxide. Tom qab lees paub tias qhov ua rau blackening ntawm LED teeb hlaws yog oxidation ntawm cov nyiaj plating txheej, Tongjia yuav qhia rau cov neeg siv khoom ntxiv xyuas cov huab cua nruj ntawm lub teeb ci thiab lub teeb kom tshem tawm txoj hauv kev ntawm noo noo nkag mus.

3. Sulfidation, chlorination, bromination
Cov nyiaj-plated txheej ntawm LED teeb hlaws tuav yuav tsim cov nyiaj sulfide thaum nws tiv nrog cov roj sulfur-muaj roj, thiab nws yuav tsim lub teeb-sensitive silver halide thaum nws hu rau acidic nitrogen-muaj chlorine thiab bromine gas, uas yuav ua rau lub teeb ci. ua dub thiab ua tsis tau. Lub teeb ci sulfur / chlorine / bromination tuaj yeem tshwm sim hauv txhua qhov txuas ntawm kev tsim khoom, kev cia khoom, kev laus, thiab kev siv cov hlaws dai thiab cov teeb ci LED. Yog li ntawd, tom qab blackening ntawm LED teeb hlaws yog txiav txim siab los ntawm sulfur / chlorine / bromination, nws raug nquahu kom cov neeg siv khoom xaiv ib qho kev tshem tawm leej faj raws li qhov txuas qhov twg sulfur / chlorine / bromination tshwm sim.
4. Tshuaj incompatibility
Lub blackening ntawm LED teeb hlaws kuj tseem tuaj yeem tshwm sim los ntawm cov tshuaj lom neeg. Hom blackening no feem ntau yuav tshwm sim nyob rau hauv lub teeb kaw nrog me me los yog tsis muaj cua txaus. Yog li ntawd, qhov blackening ntawm LED teeb hlaws dai yog txiav txim siab los ntawm cov teeb meem tshuaj lom neeg. Nws raug nquahu kom cov neeg siv khoom tshawb xyuas cov tshuaj tsis sib xws ntawm cov khoom siv hauv cov teeb pom kev zoo kom paub cov ntaub ntawv uas tsis sib haum nrog lub teeb ci.
