Dab tsi coj li cas thiab yuav ua li cas nws ua hauj lwm?

LED lights are the abbreviation of light-emitting diode (emitting diode) Lus Askiv. Cov qauv yooj yim yog ib nti electrolumines semiconductor. Siv cov kua qub los yog dawb los ntxuav kom cov hnab looj tes, Txuas nti thiab lub circuit Board nrog nyiaj hlau los yog kub hlau, kaj siab lug nyob ib ncig ntawm, tiv thaiv tus ntxhais thoob ntiaj teb, thiab thaum kawg nruab semiconductor nti ntawm lub plhaub. Vim hais tias qhov ntau lawm yog khov heev thiab tsis yooj yim rau lub caij nplooj zeeg, the LED lamp has good seismic performance.

The field of application involves the production of daily household appliances and machinery such as mobile phones, ntxhuav, thiab vaj tse.

 

1. What is an LED lighting

LED yog cov abbreviation ntawm teeb-emitting puas tau (emitting diode) Lus Askiv. Cov qauv yooj yim yog ib nti electrolumines semiconductor. Siv cov kua qub los yog dawb los ntxuav kom cov hnab looj tes, Txuas nti thiab lub circuit Board nrog nyiaj hlau los yog kub hlau, kaj siab lug nyob ib ncig ntawm, tiv thaiv tus ntxhais thoob ntiaj teb, thiab thaum kawg nruab semiconductor nti ntawm lub plhaub. Vim hais tias qhov ntau lawm yog khov heev thiab tsis yooj yim rau lub caij nplooj zeeg, the LED lamp has good seismic performance.
The field of application involves the production of daily household appliances and machinery such as mobile phones, ntxhuav, thiab vaj tse.

 

2. Ua hauj lwm tus thawj xib fwb

COJ (Light Emitting Diode) ib lub teeb-emitting puas tau, ib tug solid-state semiconductor ntaus uas yuav hloov zog hluav taws xob rau hauv pom teeb.
Nws yog ua los ntawm compounds uas muaj gallium (npog), arsenic (raws li), xov tooj (P), nroj tsuag (NUJ), lwm yam. Nws hloov tus thawj xibfwb ntawm incandescent lamp tungsten filament taws teeb emission thiab zog-txuag lamp lamp-trilor toner teeb emission, thiab ncaj qha hluav taws xob hluav taws xob mus rau hauv lub teeb. Cov yam ntxwv ntawm LED yog cuab kev heev, lub neej ntev, teeb efficiency, ntxhuav, thiab tsis muaj zog noj.

Lub plawv ntawm tus LED yog ib tug semiconductor nti. Ib kawg ntawm lub nti no txuas rau ib lub bracket, Kawg yog ib lub electrode tsis zoo, thiab lwm yam kawg txuas nrog rau lub electrode ntawm cov hwjchim mov kom tag nrho nti yog encapsulated los ntawm epoxy resin. Tus semiconductor wafer yog composed ntawm ob qhov chaw, ib sab yog ib qho P-yam semiconductor, qhov chaw mos txwv, thiab lwm yam kawg yog ib tug N-hom semiconductor, qhov twg mas electrons. Tab sis thaum no ob semiconductors muaj kev cob cog rua, Lub hlws ris P-Nunction yog ua los ntawm lawv. Thaum hluav taws xob tam sim no ua rau lub nti los ntawm cov hlau, Lub electrons yuav raug thawb rau thaj av ntawd, Qhov twg lub electrons recombine nrog qhov thiab ces emit zog nyob rau hauv daim ntawv ntawm photons. Qhov no yog tus thawj xibfwb ntawm LED emission. Lub wavelength ntawm lub teeb, yog xim, Txiav txim tau los ntawm cov ntaub ntawv uas ua rau lub hlws P-N junction.

 

3. LED light fade

The problem of LED light fade over timeis a problem that LED lamps have to face. Kev soj ntsuam yuav qhia tias tus LED yuav tej zaum muaj uninterrupted teeb lwj, thiab lub teeb lwj tiag ua rau siv LED lamps. Tamsim no, Lub teeb lwj dawb LEDs ntawm lub lag luam yog kuj hom. Qhov no tej zaum yuav yog ib qhov teeb meem thawj rau lub peb hlis ntuj mus rau neeg peg xeem neeg peg xeem. Ua kom muaj qhov uas lub teeb lwj ntawm LED?

 

There are two main factors for the light fade of LEDs:

1. LED nti siv yog tsis muaj lub cev zoo thiab cov brightness decayed sai sai, ua rau ib qho teeb meem zoo lub teeb lwj.

2. Nws muaj nws ib tug txheej txheem uas muaj ntau lawm, thiab cov LED nti tsis tau zoo derived ntawm tus PIN pin, Ua rau muaj kev kub ntxhov heev LED nti kub thiab txias thiab ntau zog attenuation.
LED teeb lwj vim muaj teeb meem zoo yog irreversible. Txawm hais tias tej tus LED lamp kuj yog ib qho khoom phooj ywg zoo phooj ywg, Nws kuj ua rau neeg khiav dej num rau ib yam twg. Cutting corners, Cov neeg tau txais kev pab los ntawm sub-them yuav tsum tau khaws cia, Ib cheeb tsam tom khw yuav zoo.

 

4. Siv tej yam kev mob:

(1) LEDS yog uas tau tsav los ntawm qhov chaw tam sim no, thiab ib co LEDs yog uas tau tsav los ntawm voltage, uas ua kom ntev li ntawm LEDs.

(2) Tus tsav tam sim no yog ntau dua li cov tsav tsheb uas tsav.
Qhov tseeb, Muaj ntau yam rau cov hniav lwj uas LED cov khoom, tab sis qhov tseem ceeb heev rau ib qho teeb meem ntawm tshav kub. Txawm hais tias ntau cov manufacturers tsis them tshwj xeeb kom tshwj xeeb kom tshwj xeeb los dissipation nyob rau hauv cov khoom thib ob, Qhov lwj ntawm cov zaub mov theem nrab leD cov khoom yuav ntau dua LED uas kub siab rau kev sib raug zoo yuav tsum muaj siab. Thermal resistance ntawm tus LED nti nws tus kheej, influence ntawm tus nyiaj glue, nyhuv tshav kub, Thiab cov colloid thiab kub hlau no kuj hais txog lub teeb attenuation.

 

5. Factors affecting the quality of LED lights

Thawj, xaiv hom LED dawb teeb. Qhov no tseem ceeb heev, Qhov zoo tshaj ntawm tus LED lub teeb dawb yuav hais tias nws yog ib qhov zoo tshaj yuav tseem ceeb heev. secondly, qhov chaw ua hauj lwm kub ntawm LED lamp beads. Raws li cov ntaub ntawv aging ntawm ib tug LED dawb teeb, tsuas yog ib tug LED dawb ua haujlwm, and the ambient temperature is at 30 degrees, ces kub ntawm lub bracket thaum cov LED ib zaug dawb ua haujlwm yuav tsis ntau tshaj 45 degrees. Lub sij hawm no, Lub neej ntawm no LED yuav zoo tagnrho. Yog tias muaj 100 LED teeb ua haujlwm rau tib lub sijhawm, thiab cov kev sib tham ntawm lawv yog lub xwb 11.4m, ces kub ntawm lub bracket dawb LED teeb nyob ib ncig ntawm lub pas dej tej zaum yuav tsis tshaj 45 degrees, Tab sis cov neeg nyob nruab nrab ntawm cov pawg dawb LED teeb yuav cuag ib kub kub ntawm 65 degrees.

Lub sij hawm no, Tus LED lamp beads yog ib txoj kev kuaj no. Ces, TUS LED dawb sib sau nyob nruab nrab yuav theoretically muaj ib lub teeb lwj, Thaum cov LED dawb teeb nyob ib ncig ntawm tus pas dej yuav muaj ib qeeb qeeb qeeb lwj. Dua, qhov chaw ua hauj lwm parameters ntawm LED lamp beads yog tsim. Raws li qhov xyaum ua tej yam tshwm sim, Tus tsav tsheb tam sim no ntawm lub teeb DAwb LED teeb, Lub tshav kub me emitted, Tau mas, tsawg dua lub brightness. Raws li qhov kev tshawb nrhiav, tsim los ntawm tus LED hnub xya circuit Court, Tus tsav tam sim no ntawm LED yog feem ntau tsuas 5-10mA. Rau cov khoom uas muaj ib tug xov tooj loj ntawm cov beads loj, xws li ntau tshaj 500 los sis ntau tshaj, Tus tsav tam sim no feem ntau yog feem ntau tsuas 10-15mA, thiab tus tsav tam sim no hais txog LED teeb yog xwb 15-18mA, thiab ob peb tus neeg muab nws tam sim no yog tsim los yuav tau ntau tshaj 20mA. Qhov xyaum ua tej yam kuj qhia tau hais tias nyob rau hauv cov tsav tam sim no ntawm 14mA, thiab nrog rau qhov ntxiv ntawm lub hau kom tiv thaiv airflow, cua kub hauv cua txias mus txog 71 degrees. Cov khoom uas tsis muaj lwj, Lub teeb xoom hnyav rau xoom teev yog xoom, thiab lub teeb xuaj hniav lwj 2000 teev 3%. Qhov no qhia tau hais tias kev siv no qes-lwj LED dawb tau mus txog nws cov nyiaj ntau heev nyob rau hauv tej ib cheeb tsam. puas tsuaj. Vim hais tias lub Rooj Tswjhwm Saib cov aging muaj tsis muaj kev sib nrauj, Lub tshav kub generated los ntawm tus LED thaum lub lag luam tsis tau yuav ua rau sab nraud.
