Yuav ua li cas txhawm rau txheeb xyuas qhov tsis sib xws ntawm kev pom kev pom ntawm LED qhov muag tiv thaiv chav kawm teeb
Peb paub tias cov txheej txheem hauv tebchaws tau teev tseg tias qhov nruab nrab qhov pom kev zoo ntawm lub desktop hauv chav teeb pom kev zoo ntawm chav kawm hauv tsev kawm ntawv yuav tsum tsis pub tsawg dua 300lx, thiab qhov tsis sib xws ntawm qhov pom kev yuav tsum tsis pub tsawg dua 0.7. Yog li yuav piav qhia qhov sib xws ntawm ib puag ncig lub teeb tsim los ntawm LED qhov muag tiv thaiv chav kawm teeb? Cia' saib tam sim no!
Dab tsi yog teeb pom kev zoo ib yam? Kev teeb pom kev zoo ib yam hais txog qhov piv txwv ntawm qhov pom kev tsawg kawg rau nruab nrab qhov pom kev. Cov lej suav yog teeb pom kev zoo ib yam=qhov teeb pom kev yam tsawg kawg nkaus/qhov nruab nrab qhov pom kev zoo. Yog tias qhov nruab nrab qhov pom kev zoo yog 300lx, tom qab ntawd qhov teeb pom kev zoo tsawg kawg yuav tsum tsis qis dua 210lx.
Nov yog yam uas yuav tsum nco ntsoov:
1. Kev teeb pom kev zoo ib yam hais txog qhov piv txwv ntawm qhov pom kev tsawg kawg rau qhov nruab nrab qhov pom kev, tsis yog qhov piv txwv ntawm qhov pom kev siab tshaj plaws, lossis qhov piv ntawm lwm qhov kev pom kev.
2. Lub teeb pom kev zoo ib yam hais txog qhov piv txwv ntawm qhov teeb pom kev yam tsawg kawg nkaus rau qhov pom kev nruab nrab ntawm lub rooj, tsis yog qhov piv ntawm qhov pom kev mus rau qhov pom kev nruab nrab ntawm lwm cov ntsiab lus hauv chav kawm.
Yog li ntawd, qhov nruab nrab qhov pom kev pom ntawm chav kawm ib puag ncig teeb pom kev los ntawm lub teeb tiv thaiv qhov muag hauv chav kawm yuav tsum tshaj 300lx, thiab qhov piv txwv ntawm qhov teeb pom kev yam tsawg kawg nkaus ntawm lub rooj rau qhov pom kev nruab nrab nruab nrab yuav tsum tsis pub tsawg dua 70%, uas yog qhov zoo tshaj uniformity ntawm illuminance. Qhov sib xws ntau dua qhov kev faib lub teeb txhais tau tias zoo dua qhov pom kev thiab ua rau pom kev zoo dua. Qhov ze dua qhov pom kev zoo ib yam yog 1, zoo dua; ntawm qhov tsis sib xws, nws me dua, qhov pom kev nkees yuav nce ntxiv.
