Raws li cov khoom siv teeb pom kev tsis tseem ceeb rau kev tsav tsheb hmo ntuj, lub teeb tsheb tau nce ntxiv raws li cov khoom nyiam los ntawm ntau thiab ntau lub tuam txhab tsheb nrog kev txhim kho txuas ntxiv ntawm LED thev naus laus zis. LED tsheb teeb yog hais txog cov teeb uas siv cov tshuab LED ua lub teeb pom kev zoo sab hauv thiab sab nraum lub tsheb. Cov khoom siv hluav taws xob sab nraud suav nrog ntau yam qauv xws li kev txwv thermal, electromagnetic compatibility (EMC), thiab kev ntsuas kev thauj khoom. Cov LED tsheb teeb no tsis tsuas yog txhim kho lub teeb pom kev zoo ntawm lub tsheb, tab sis kuj tsim kom muaj qhov chaw zoo nkauj sab hauv.

Kev tsim kho ntawm LED headlights
Cov khoom tseem ceeb ntawm LED muaj xws li kub hlau, LED nti, lub nplhaib reflective, cathode hlau, yas hlau, thiab anode hlau.
Qhov tseem ceeb ntawm LED yog cov nti uas muaj p-hom semiconductor thiab n-hom semiconductor, thiab cov qauv tsim ntawm lawv yog hu ua pn junction. Nyob rau hauv PN hlws ris ntawm tej yam khoom semiconductor, thaum ib tug tsawg tus nqi ntawm cov cab kuj recombine nrog rau feem ntau ntawm cov cab kuj, lub zog ntau tshaj yog tso tawm nyob rau hauv daim ntawv ntawm lub teeb, converting hluav taws xob rau hauv lub teeb lub zog. Thaum qhov hluav taws xob rov qab siv rau pn kev sib tshuam, nws yog qhov nyuaj rau kev txhaj tshuaj me me ntawm cov neeg nqa khoom, yog li luminescence yuav tsis tshwm sim. Hom diode no tsim los ntawm lub hauv paus ntsiab lus ntawm kev txhaj tshuaj raws li luminescence yog hu ua lub teeb-emitting diode, feem ntau abbreviated li LED.

Cov txheej txheem luminous ntawm LED
Nyob rau hauv pem hauv ntej kev tsis ncaj ncees ntawm LED, tus nqi nqa khoom yog txhaj, recombined, thiab radiated mus rau hauv lub semiconductor nti nrog tsawg zog lub teeb. Lub nti yog encapsulated hauv huv epoxy resin. Thaum tam sim no dhau los ntawm cov nti, cov hluav taws xob tsis zoo txav mus rau thaj tsam qhov muaj txiaj ntsig zoo, qhov chaw uas lawv ntsib thiab rov ua dua. Ob leeg electrons thiab qhov ib txhij dissipate thiab tso photons.
Qhov loj dua qhov bandgap, lub zog ntau dua ntawm cov photons generated. Lub zog ntawm photons muaj feem xyuam nrog cov xim ntawm lub teeb. Nyob rau hauv qhov pom spectrum, xiav thiab ntshav lub teeb muaj lub zog siab tshaj plaws, thaum lub teeb txiv kab ntxwv thiab liab muaj lub zog qis tshaj. Vim muaj qhov sib txawv ntawm qhov sib txawv ntawm cov khoom sib txawv, lawv tuaj yeem tawm lub teeb ntawm cov xim sib txawv.
Thaum lub LED nyob rau hauv pem hauv ntej ua hauj lwm lub xeev (xws li thov rau pem hauv ntej voltage), tam sim no ntws los ntawm lub anode mus rau lub cathode ntawm lub LED, thiab lub semiconductor siv lead ua emits lub teeb ntawm txawv xim ntawm ultraviolet mus infrared. Qhov kev siv ntawm lub teeb nyob ntawm qhov loj ntawm qhov tam sim no. LEDs tuaj yeem muab piv rau hamburgers, qhov twg cov khoom siv luminescent zoo li "cov nqaij patty" hauv cov qhaub cij, thiab cov hluav taws xob sab sauv thiab sab qis zoo li lub khob cij nrog cov nqaij nruab nrab. Los ntawm txoj kev kawm ntawm cov ntaub ntawv luminescent, tib neeg tau maj mam tsim ntau yam khoom siv LED nrog lub teeb xim ntau dua thiab ua haujlwm zoo. Txawm hais tias muaj ntau yam kev hloov pauv hauv LED, nws txoj cai luminescent thiab cov qauv tseem tsis hloov pauv. Jinjian Laboratory tau tsim ib txoj kab kev ntsuas uas npog cov chips rau cov teeb pom kev zoo hauv LED optoelectronic kev lag luam, muab ib qho kev daws teeb meem uas npog txhua yam los ntawm cov khoom siv raw rau cov khoom siv, suav nrog kev soj ntsuam tsis ua haujlwm, cov yam ntxwv ntawm cov khoom siv, ntsuas ntsuas, thiab lwm yam., los pab cov neeg siv khoom. txhim kho qhov zoo, tawm los, thiab kev ntseeg siab ntawm LED cov khoom.

Qhov zoo ntawm LED teeb
1. Kev txuag hluav taws xob: LEDs hloov hluav taws xob hluav taws xob ncaj qha mus rau hauv lub teeb lub zog, tsuas yog ib nrab ntawm cov teeb pom kev zoo, uas yuav pab txo qis kev siv roj thiab tsis txhob muaj kev puas tsuaj rau lub tsheb circuits vim yog cov load tam sim no ntau dhau.
2. Kev tiv thaiv ib puag ncig: LED spectrum tsis muaj ultraviolet thiab infrared rays, muaj hluav taws kub tsis tshua muaj hluav taws xob, tsis muaj hluav taws xob, thiab qis glare. LED pov tseg yog recyclable, tsis muaj mercury, tsis muaj kuab paug, nyab xeeb rau kov, thiab yog ib qho teeb pom kev zoo ntsuab.
3. Lub neej ntev: Tsis muaj qhov xoob hauv lub teeb LED lub cev, tsis txhob muaj teeb meem xws li filament burning, thermal deposition, thiab lub teeb lwj. Raws li qhov tsim nyog tam sim no thiab qhov hluav taws xob, lub neej ua haujlwm ntawm LED tuaj yeem ncav cuag 80000 txog 100000 teev, uas yog ntau dua 10 npaug ntev dua li cov teeb pom kev zoo ib txwm muaj. Nws muaj cov yam ntxwv ntawm kev hloov ib zaug thiab siv lub neej.
4. High brightness thiab kub tsis kam: LEDs ncaj qha hloov hluav taws xob hluav taws xob rau hauv lub teeb lub zog, tsim kom muaj cua sov tsawg, thiab tuaj yeem kov tau zoo.
5. Qhov loj me: Cov neeg tsim qauv tuaj yeem hloov pauv tus qauv ntawm cov teeb pom kev zoo kom muaj ntau haiv neeg ntawm lub tsheb styling. LED yog nyiam heev los ntawm cov tuam txhab tsheb vim nws qhov zoo.
6. Kev ruaj ntseg siab: LEDs muaj zog seismic kev ua tau zoo, yog encapsulated hauv resin, tsis yooj yim tawg, thiab yooj yim rau khaws thiab thauj.
7. High luminous purity: LED xim yog vivid thiab ci, tsis tas yuav tsum tau rau lub teeb pom kev lim dej, thiab lub teeb yoj yuam kev yog tsawg dua 10 nanometers.
8. Lub sij hawm teb ceev ceev: LEDs tsis xav tau lub sij hawm pib kub thiab tuaj yeem tso lub teeb nyob rau hauv ob peb microseconds, thaum cov iav qhov muag teev yuav tsum ncua 0.3 vib nas this. Hauv cov ntawv thov xws li lub teeb taillights, cov lus teb ceev ceev ntawm LEDs pab tiv thaiv kev sib tsoo tom qab kawg thiab txhim kho kev nyab xeeb ntawm kev tsav tsheb.
