Dab tsi yog cov yam ntxwv ntawm LED kev kawm teeb?
As long as the cost of LED educational lights decreases with the continuous improvement of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED educational lamps. The country is paying more and more attention to lighting energy saving and environmental protection issues, and has been vigorously promoting the use of LED educational lamps. So what are the characteristics of LED educational lights? That's a lot, let's see the LED educational light manufacturer Xiaobian to reveal it for you. please watch the following part!
1. Kev txuag hluav taws xob. Kev siv lub zog ntawm cov LEDs dawb tsuas yog 1/10 ntawm cov roj teeb thiab 1/4 ntawm lub zog- txuag teeb.
2. Longevity. The lifespan can reach more than 100,000 hours, which can be described as "once and for all" for ordinary household lighting.
3. Nws tuaj yeem ua haujlwm ntawm kev kub ceev. Yog hais tias lub zog - txuag lub teeb yog nquag pib los yog tua, lub filament yuav tig dub thiab sai sai, yog li nws muaj kev nyab xeeb dua.
4. Khoom- lub xeev ntim khoom, yog hom lub teeb txias. Yog li nws yog ib qho yooj yim rau kev thauj thiab nruab, tuaj yeem ntsia tau rau hauv cov khoom me me thiab kaw, tsis ntshai kev co.
5. LED thev naus laus zis tau nce zuj zus nrog txhua hnub dhau mus, nws cov kev ua haujlwm luminous ua rau muaj kev cuam tshuam zoo heev, thiab tus nqi pheej yig dua. Ib lub sijhawm ntawm cov LEDs dawb nkag mus rau hauv tsev yog sai sai.
6. Kev tiv thaiv ib puag ncig, tsis muaj cov tshuaj mercury txaus ntshai. Cov khoom sib sau ua ke ntawm LED kev kawm teeb pom kev tuaj yeem tshem tau yooj yim heev, thiab tuaj yeem rov ua dua los ntawm lwm tus yam tsis tau siv los ntawm cov chaw tsim khoom.
7. Lub teeb faib tshuab nthuav dav lub teeb pom kev zoo ntawm LED teeb rau hauv qhov chaw teeb pom kev zoo, ua kom lub ntsej muag ci ntsa iab, tshem tawm glare, sublimates qhov muag pom, thiab tshem tawm qhov pom kev qaug zog.
8. Kev tsim qauv ntawm lub lens thiab lub teeb ci. Lub lens muaj lub luag haujlwm ntawm kev tsom xam thiab kev tiv thaiv tib lub sijhawm, tsis txhob rov qab khib nyiab ntawm lub teeb thiab ua rau cov khoom zoo dua thiab zoo nkauj.
9. High-lub zog LED tiaj tus pawg pob, thiab kev tsim qauv ntawm lub tshuab hluav taws xob thiab lub teeb lub teeb. Nws tag nrho lav cov kev xav tau ntawm cov cua kub dissipation thiab kev pab cuam lub neej ntawm LEDs, thiab cov hauv paus ntsiab lus txaus siab rau qhov kev txiav txim siab ntawm cov qauv thiab cov duab ntawm LED kev kawm teeb. Nws muaj cov yam ntxwv tshwj xeeb ntawm LED kev kawm teeb.
10. Kev txuag hluav taws xob tseem ceeb. Siv ultra- ci ntsa iab thiab siab - lub zog LED lub teeb ci, nrog rau siab - lub zog siv hluav taws xob, nws tuaj yeem txuag tau ntau dua 80 feem pua ntawm hluav taws xob ntau dua li cov teeb pom kev zoo, thiab qhov ci ci yog 10 lub sij hawm uas lub teeb incandescent nyob rau hauv tib lub hwj chim.
11. Lub neej ntev ultra-ntev yog ntau tshaj 50,000 teev, uas yog ntau tshaj 50 npaug ntawm cov roj teeb tungsten. LED txais cov txheej txheem ntim khoom zoo heev thiab siab heev - eutectic vuam, uas lav tag nrho lub neej ntev ntawm LED.
12. Tsis muaj stroboscopic. Ntshiab DC ua haujlwm, tshem tawm qhov pom kev qaug zog tshwm sim los ntawm stroboscopic ntawm cov teeb pom kev zoo ib txwm muaj.
13. Kev tiv thaiv ib puag ncig ntsuab. Tsis muaj cov hmoov txhuas, mercury thiab lwm yam khoom muaj kuab paug, tsis muaj kuab paug rau ib puag ncig.
14. Kev cuam tshuam tsis zoo, hluav taws xob muaj zog, tsis muaj ultraviolet (UV) thiab infrared (IR) hluav taws xob. Tsis muaj filament thiab iav plhaub, tsis muaj teeb meem ib txwm teeb fragmentation, tsis muaj kev puas tsuaj rau tib neeg lub cev, tsis muaj hluav taws xob.
15. Ua haujlwm nyob rau hauv qis thermal voltage, muaj kev nyab xeeb thiab txhim khu kev qha. Qhov kub thiab txias tsawg dua los yog sib npaug li 60 degree (thaum ambient kub Ta=25 degree ).
16. Dav voltage ntau, universal LED kev kawm teeb. 85V 264VAC tag nrho voltage ntau qhov tam sim no kom ntseeg tau tias lub neej thiab ci ntsa iab tsis cuam tshuam los ntawm qhov hloov pauv ntawm qhov hluav taws xob.
17. Siv PWM tas li tam sim no thev naus laus zis, kev ua haujlwm siab, tsis tshua muaj cua sov thiab siab tsis tu ncua tam sim no precision.
18. Txo cov kab poob thiab tsis muaj kuab paug rau hauv daim phiaj fais fab. Lub zog muaj zog ntau dua lossis sib npaug rau 0.9, kev sib txawv sib txawv Tsawg dua lossis sib npaug li 20 feem pua, EMI ua raws li cov qauv thoob ntiaj teb, txo cov hluav taws xob poob ntawm cov kab hluav taws xob thiab tsis txhob muaj kev cuam tshuam ntau zaus thiab muaj kuab paug. rau cov kab hluav taws xob.
19. Universal tus qauv teeb lub teeb, uas tuaj yeem hloov pauv cov teeb halogen uas twb muaj lawm, cov teeb ci thiab cov teeb fluorescent.
20. Lub teeb pom kev zoo ntawm lub teeb pom kev zoo tuaj yeem siab txog li 80lm / w, ntau yam ntawm LED kev kawm teeb tuaj yeem xaiv qhov kub thiab txias, nrog cov xim rendering siab thiab cov xim zoo nkauj.
