LEDs muaj qhov ci ci zoo dua thiab ua tau zoo tshaj qhov ua tau zoo dua qub ultra- qhov muag teeb ci hauv kev siv hluav taws xob.
1. Kev sib piv Brightness: Lumen tus nqi txiav txim qhov tshwm sim tiag tiag
Brightness yog ntsuas ncaj qha hauv lumens (lm), tsis yog wattage. Piv txwv li:
- Ib txwm muaj 100W incandescent qhov muag tawm kwv yees li 1600 lumens, siv hluav taws xob ntau;
- Lub teeb ci LED ntawm qhov sib npaug yuav tsum tsuas yog 15-20W, nrog cov khoom siv high-end LED ncav cuag tshaj 3000 lumens, deb tshaj qhov teeb pom kev zoo ib txwm muaj.
2. Kev Siv Hluav Taws Xob thiab Kev Tiv Thaiv Ib puag ncig: LEDs muab qhov zoo tshaj plaws
LED photoelectric conversion efficiency yog kwv yees li 80-100 lumens / watt, thaum ib txwm incandescent qhov muag teev tsuas yog ua tiav 10-17 lumens / watt. Qhov no txhais tau hais tias LEDs ua tiav tib lub ci ci nrog tsuas yog 1/6 lub zog, uas ua rau muaj kev txuag nyiaj ntau ntawm cov nqi hluav taws xob thiab txo cov pa roj carbon monoxide nyob rau lub sijhawm ntev.
3. Kev nyab xeeb thiab siv tau cov xwm txheej
Ultra- qhov muag teeb ci tuaj yeem ncav cuag qhov kub siab tshaj 200℃thaum lub sijhawm ua haujlwm, ua rau muaj kev pheej hmoo ntawm kub hnyiab lossis hluav taws kub; LED qhov kub thiab txias feem ntau tswj tau qis dua 50 degree, ua rau lawv haum rau cov menyuam yaus chav, cov txee, thiab cov ntawv siv zoo sib xws. Piv txwv li, Philips Cool LED Noob muab ob qho tib si siab -brightness txias dawb lub teeb (6500K xim kub) thiab illumination tas li thaum tswj tsis tshua muaj cua sov.
Thaum xaiv cov khoom siv teeb pom kev zoo, ua qhov tseem ceeb ntawm lumen tso zis thiab xim kub tsis kam. Brightness specifications rau mainstream LED khoom yog standardized; Piv txwv li, ib qho "E27 interface 18W LED qhov muag teev" feem ntau sib haum rau 2200 lumens ntawm lub teeb sov, thaum dual- qhov chaw LED qab nthab teeb tuaj yeem ncav cuag 5000 lumens los ntawm kev ua kom cov LED ntom ntom, ua tau raws li qhov xav tau ntawm cov teeb pom kev zoo ntawm qhov chaw loj.
