Lub brightness ntawm LED txee screen
LED txee cov ntxaij vab tshaus tau dhau los ua ci ntsa iab dua li LED thev naus laus zis nce qib. Qhov no tsis txhais hais tias tag nrho cov kab txaij yuav muaj xim zoo nkauj; nyob rau hauv kev muaj tiag, lub teeb yuav tsis txawm xav tau nyob rau hauv tej lub sij hawm. Lub teeb pom kev zoo hauv lub txee yog ib qho piv txwv ntawm qhov no.
Lumens are used to determine the brightness of LEDs. You'll probably need a certain number of lumens, depending on how you're going to use the LED products. You generally don't want anything brighter than 600 Lumens per foot for accent lighting. Still, it all depends on your personal preference for brightness for other applications where you need more light. So, make a note of the Lumens/length and the LEDs/length, as both will significantly impact the light quality and form of light the strip emits.
Q:LED screen specifications daim ntawv
Ans:Specifications such as operating temperature (normally -20°C +55°C for outdoor use), relative humidity (normally 10-99%), refresh rate (> 3000 Hz is needed for best TV shooting), contrast ratio (useless if not related to external luminance values), and the number of color shades (you can get 281 trillion with 16-bit processing – which will prove high quality) are more linked to screen performance.
Q:Qhov tsawg kawg nkaus saib qhov nrug yog dab tsi?
Ans:Qhov kev ncua deb tshaj plaws ntawm cov duab thiab cov ntawv tuaj yeem paub qhov txawv yam tsis muaj pixilation yog hu ua qhov pom qhov tsawg kawg nkaus. Txawm li cas los xij, qhov no tsis txwv qhov muaj peev xwm ntawm cov duab lossis cov ntawv nyeem kom haum los ntawm qhov ze dua. Piv txwv li, cov yeeb yaj kiab ntawm LED qhia cov khoom hauv peb lub khw hauv online tau coj los ntawm qhov deb ntawm 4-5 meters deb ntawm cov zaub rau koj qhov yooj yim.
