Anthu amayezera magetsi pogwiritsa ntchito mayunitsi osiyanasiyana monga Candela, Lux, ndi Lumens. Kodi munayamba mwaganizapo zowunika magetsi omwe akugwiritsa ntchito iliyonse mwa mayunitsiwa?
Mutha kulowa m'mavuto potero chifukwa mayunitsi oyezera kuwala a Candela, Lux, ndi Lumens nthawi zambiri amasinthasintha. Choncho ndinaganiza kuti ndikupulumutseni ku chisokonezo ichi pobweretsa kusiyana kwawo.
Mayunitsi a Candela, Lux, ndi Lumens amayezera kulimba kwa kuwala. Lux amatanthauza kuchuluka kwa kuwala komwe kumafika pa chinthu. Ndipo Lumens ndi Candela ndi ma metric omwe amagwiritsidwa ntchito powunika kuchuluka kwa kuwala.
Komabe, mawu atatuwa nthawi zambiri amagwiritsidwa ntchito molakwika pozindikira kuwala kwa kuwala. Ichi ndichifukwa chake muyenera kudziwa zomwe zikutanthauza komanso zomwe zimalekanitsa mayunitsi wina ndi mnzake.
Tiyeni tilowe muzokambirana kuti tidziwe zambiri.
Candela ndi chiyani?
Candela akunena za Luminous Intensity ya gwero lowala. Mawuwa adachokera ku liwu lachilatini 'Candela' ndipo amagwirizana ndi mphamvu ya kandulo. Mwachitsanzo, Candela imodzi imakhala yofanana ndi kuwala kwa kandulo.
M'mawu ang'onoang'ono, Candela amayesa kukula kwa kuwala kumbali ina kapena ngodya inayake. Sizikudziwika? Ganizirani za kuwala kwa laser; imatsogolera kuwala ku mbali ina yake. Ichi ndichifukwa chake mtengo wa Candela ndiwokwera kwambiri mu laser kapena ma spotlights.
Kodi Lux ndi chiyani?
Lux (lx) ndi gawo loyezera pakuwunikira. Imawonetsa kuchuluka kwa kuwala komwe kumawonekera pa lalikulu mita.
Chifukwa chake, pamlingo wa Lux, muyenera kuganizira dera la chipindacho kapena mtunda wa gwero la kuwala kuchokera pamalo enaake. Pamenepa, mtengo wa Lux umafanana mosiyana ndi sikweya mpaka kutalika kwake. Ndiye kuti, pamene mtunda ukuwonjezeka, mtengo wa Lux umachepa. Choncho, kuwala komwe kumawoneka kowala m'chipinda chaching'ono sikudzawoneka ngati kowala pamene kuikidwa m'chipinda chachikulu.
M'mawu am'mabuku, Lux amawonetsedwa ngati - 1 lx ndi ofanana ndi 1lm/m^2. Ndiye kuti, mtengo wa Lux umadalira Lumens (lm). Chifukwa chake, tiyeni tidumphire ku Lumens kuti tiphunzire bwino Lux-
Kodi Lumen ndi chiyani?
Mtengo wa Luminous Flux umayesedwa mu Lumen (lm). Ndilo mawu omwe amagwiritsidwa ntchito kwambiri pofotokoza mphamvu ya magetsi.
Ma lumens amasonyeza mphamvu yonse ya gwero la kuwala. Ndiko kuti, kuwala konse komwe kuwala kumatulutsa ndi Lumens. Mosiyana ndi Candela (cd), Lumens samawerengera kuwunikira kuchokera mbali ina. M'malo mwake zikuwonetsa lumens yaiwisi.
Lumen yaiwisi iyi imayesa kuwala kwa gwero la kuwala kuchokera kumbali zonse. Chotsatira chake, mosasamala kanthu za ngodya yotulutsa kuwala, mtengo wa Lumen umakhalabe wokhazikika.
Kuphatikiza apo, mtengo wa Lumens umasiyana ndi mtundu wa kuwala, mtundu, ndi gwero lamagetsi.
Candela vs Lux vs Lumens - Kodi Pali Kusiyana Kotani?
Kusiyana kwakukulu pakati pa Candela, Lux, ndi Lumens kuli motere patebulo ili pansipa-
| zofunika | Candela | Lumens | Lux |
| Tanthauzo | Candela ndi mulingo wowala wa gwero la kuwala pa ngodya inayake ndi kolowera. | Lumen imasonyeza kutulutsa kwathunthu kwa kuwala kumbali zonse. | Kuchuluka kwa zowunikira zomwe zimagunda pa lalikulu mita imodzi ndi Lux. |
| Kuyeza Unit Of | Luminous Intensity | Flux Wowala | Kuwala |
| Chizindikiro (SI) | cd | lm | lx |
Candela ndiye gawo loyezera la Luminous Intensity. Pakadali pano, Lumen ndi Lux ndi magawo a Luminous Flux ndi Illuminance.
M'mawu osavuta, Candela akuwonetsa momwe kuwala kulili kowala; Lux amayesa momwe chinthu chimawonekera pakuwala. Ndipo Lumen ikuwonetsa kutulutsa kwathunthu komwe gwero la kuwala limapereka.
Kusintha kwa mtunda kumakhudza mtengo wa Lumen ndi Lux, koma Candela amakhalabe wokhazikika. Izi ndichifukwa choti mtengo wa Candela umadalira ngodya m'malo mwa mtunda.
Candela vs Lux vs Lumens - Kodi Zimakhudzana Bwanji?
Ubale wodziwika kwambiri pakati pa mawu atatuwa ndikuti onse ndi gawo loyezera la kuwala. Kuti timveketse bwino lingaliroli, tiyeni tifike ku gwero la mawu awa-
Lumens ndi mtundu wochokera ku Candela. Mawu onsewa amayesa kuwala; ndiko kuti, iwo amanena kuwala kwa gwero la kuwala. Kusiyana kwake ndikuti ma lumens amatengera kuwala kochokera mbali zonse. Mosiyana ndi izi, Candela amawona kuti ndi njira inayake.
Apanso, unit Lux ndiye muyeso wa Lumens pa lalikulu mita. Ndilo gawo lochokera ku Lumens. M'masamu, 1 lx = 1lm/m^2. Equation iyi imapereka chithunzithunzi cholondola cha kuwala kwa kuwala kuposa ma Lumens.
Ndipo chochititsa chidwi kwambiri ndichakuti Lux ndiye mtundu wamakandulo apamapazi (mawu akale omwe amanena za Candela).
| Kuchokera ku Derived from Lux ———————→ Lumens ——————–→ Candela 1 lx = 1 lm/m2 = 1 cd·sr/m2 |
Chifukwa chake, Candela, Lux, ndi Lumens amalumikizana wina ndi mnzake. Komabe, amatchula mitundu itatu yosiyana, koma ndi yolumikizana komanso yosinthika.
Chigawo chathunthu chimakhala ndi ngodya yolimba ya 4π steradians, kotero kuti kuwala komwe kumawonekera mofanana mbali zonse kumakhala ndi kuwala kokwanira.
1 cd × 4πsr = 4π cd · sr ≈12.57 lm.
Zomwe Zimakhudza Mtengo Wa Candela Vs. Lux vs. Lumens
Makhalidwe a Candela, Lux, ndi Lumens amasinthasintha pazifukwa izi:
Distance
Mtunda wapakati pa chinthu ndi gwero lowala umakhudza mayendedwe a Lux ndi Lumens. Zili choncho chifukwa masikweya a mtunda amafanana mosiyana ndi mayunitsiwa.
Kuchulukitsa kutalika ndi kawiri, mtengo wa lx udzatsika mpaka 1/4th yamtengo wapatali. Koma mtunda sukhudza mtengo wa Candela, chifukwa umaimba ndi ngodya osati mtunda.
Angle of Radiance
Mbali yopangidwa ndi gwero la kuwala imakhudza kuunikira. Kang'ono kakang'ono kameneka ndi, mtengo wa Candela ndi Lux; kuwala kumawalira.
Kuphatikiza apo, malo owunikira amawonjezeka chifukwa cha ngodya zazikulu za kuwala, kusunga mtengo wa lm wosasintha.
Luminous Mwachangu
Kuwala kowala kumayesa kuthekera kwa gwero la kuwala kuti apange magetsi owala. Zimatengera mphamvu ya gwero la Wattage ndi Lumens. Kuwala kowala kumawonjezeka pamene mtengo wa Watt ukuchepa.
Ndiko kuti, kuwala kowala kwambiri kumakhala kowala kwambiri, kuwala kumakhala kowala.
Kodi Standard Light Measuring Unit ya LED Strip ndi iti?
Chigawo choyezera kuwala kwa LED Stipe ndi Lumens. Koma, nthawi zambiri timalakwitsa poyesa kuwala kwa mikwingwirima ya LED ndi Wattage. Uwu ndi mchitidwe wopanda chilungamo chifukwa kuwala kosiyana kumakhala ndi kuwala kosiyanasiyana.
Chifukwa chake, njira yolondola yowonera magwiridwe antchito a mzere wa LED ndi Lumen pa phazi / mita.
Komabe, mtengo wa Lumens umasiyana ndi mtundu wa mzere wa LED. Mwachitsanzo, mikwingwirima yoyera ya LED imakhala ndi mtengo wapamwamba wa Lumen kuposa mikwingwirima yamtundu wa LED.
Kodi Ma Lumens & Wattage Amagwirizana Bwanji?
Ma lumens amawonetsa kutulutsa konse komwe gwero la kuwala limatulutsa, pomwe Wattage ndi mphamvu yomwe imagwiritsidwa ntchito kuyatsa. Komabe, kuti muweruze momwe kuwalako kumagwirira ntchito, muyenera kuganizira momwe kuwalako kumagwirira ntchito podziwa kuchuluka kwa lumen ndi Wattage.
Pankhaniyi, mababu opulumutsa mphamvu ndi omwe amagwira ntchito bwino. Chifukwa amapanga lumen yapamwamba kwambiri pogwiritsa ntchito mphamvu zochepa (Wattage). Ndicho chifukwa chake amatchedwa mababu opulumutsa mphamvu.
Mphamvu ya kuwala imawerengedwa ngati Lumen Per Watt. Ndiko kuti
Kuwala Mwachangu, E = lm/W
Chifukwa chake, mphamvu ya kuwala imawonjezeka pamene mphamvuyo ikuyenda bwino. Panthawi imodzimodziyo, magetsi amphamvu kwambiri amachepetsa bilu yanu yamagetsi.
