Migumisiro yemavara akasiyana-siyana echiedza pamuviri womunhu
Mavara mumhando dzakasiyana-siyana ane maitiro akasiyana paganda. Heano mamwe akajairika spectrum mavara uye zvazvinoita paganda:
Ultraviolet (UV): Ultraviolet mwaranzi yakakamurwa kuita UVA, UVB uye UVC. UVA ine hurefu hwakareba uye inogona kupfuura nepagirazi, uye inonyanya kukonzera kuchembera kweganda uye kuunyana. UVB ine hurefu hupfupi uye inogona kukonzera kupisa kwezuva uye solar dermatitis. Ichowo chimwe chezvikonzero zvikuru mukukonzera kenza yeganda. UVC ine hupfupi hwewavelength, inowanzotorwa nemhepo yepasi, uye ine zvishoma zvinokanganisa muviri wemunhu.
Chiedza chebhuruu: Chiedza chebhuruu chiri mune yepamusoro frequency bhendi yeinooneka spectrum. Mumakore achangopfuura, nekuda kwekuzivikanwa kwezvigadzirwa zvemagetsi, kuratidzwa kwevanhu kune chiedza chebhuruu kwakawedzera. Kugara kwenguva refu kuchiedza chebhuruu kunogona kukonzera kuzvimba kweganda, kukuvadza epidermal masero, uye kukurumidze kukwegura kweganda. Mukuwedzera, chiedza chebhuruu chinogonawo kukanganisa kurara uye kukanganisa kupora kweganda uye kuberekwa patsva.
Chiedza chitsvuku: Chiedza chitsvuku chine urefu hwakareba uye chinogona kupinda mukati meganda. Chiedza chitsvuku chinofungidzirwa kuti chinokurudzira kupararira kweropa, kuwedzera kugadzirwa kwe collagen uye kuvandudzwa kwesero, zvichibatsira kuvandudza kunaka kweganda uye kuderedza wrinkles.
Chiedza cheGreen: Chiedza chegirini chinowanikwa pakati pe-wavelength renji yeinooneka spectrum uye chine zvishoma paganda. Zvisinei, chiedza chegirini chinoshandiswa kurapa zvimwe zvinetso zveganda, zvakadai sekutsvuka uye kuva nemavara. Inogona kubatsira kuderedza kuzvimba uye kukurudzira ganda rinozorodza uye kugadzirisa.
Yellow light: Yero mwenje zvakare chikamu chechiedza chinooneka uye chine wavelength yakareba. Yero mwenje ine zvishoma paganda, asi inoshandiswa mukurapa runako kupenya ganda uye kuderedza kuunyana uye kuzvimba.
Zvakakosha kucherechedza kuti migumisiro yemavara akasiyana-siyana mumucheka paganda zvakare yakanyatsobatana nezvinhu zvakadai sechiedza chechiedza, nguva yekuratidzira uye kusiyana kwega. Mukuwedzera, kunyanya kuvhenekera kumagetsi eUV kunogona kukonzera kukuvara kweganda uye matambudziko ehutano, saka zvinokurudzirwa kutora matanho ekudzivirira akakodzera, akadai sekushandisa sunscreen, kupfeka ngowani uye magirazi ezuva, kuderedza mhedzisiro ye UV rays.
Tekinoroji yeLED yakashandura nzira yatinovhenekera nayo dzimba dzedu nemabhizinesi. Haisi kungounza kushandiswa kwesimba kune chiedza, inovandudzawo kunaka kwechiedza, zvichiita kuti zvigadziriswe kune zvakasiyana-siyana zvekugadzirisa. LED inomirira light-emitting diode, semiconductor mudziyo unoburitsa chiedza kana magetsi achipfuura napo. Tekinoroji ye LED inoshanda zvakanyanya kupfuura yechinyakare incandescent uye mwenje wefluorescent. Asi ma LED anoshanda sei?
Chimwe chezviratidzo zvakakosha zvekuvhenekera kwemwenje ndiko kushandiswa kwesimba. Tekinoroji ye LED inozivikanwa nekushomeka kwesimba rekushandisa, zvichiita kuti ive sarudzo yakakurumbira yekuvhenekesa kwekugara uye kwekutengesa. Asi magirobhu eLED anochengetedza simba rinosvika 80% kupfuura echinyakare incandescent bulbs uye inosvika 20-30% kupfuura magirobhu efluorescent. Kudzikiswa kwekushandiswa kwesimba hakungodzikisi mabhiri emagetsi evatengi chete asiwo kunobatsira zvakanyanya kuderedza kuburitswa kwekabhoni, zvichiita kuti tekinoroji yeLED ive sarudzo ine hushamwari hwekuvhenekesa.
Zvese mune zvese, tekinoroji ye LED inoshanda zvakanyanya maererano nekushandiswa kwesimba, hupenyu hurefu, kubuda kwechiedza uye kudzoreka. Simba rayo rakaderera kushandisa, hupenyu hurefu, kubuda kwechiedza chepamusoro uye kushanda-pakarepo kunoita kuti ive sarudzo yakanakisa yekuvhenekesa kana ichienzaniswa neyekare incandescent uye mwenje wefluorescent. Sezvo kudiwa kwemagetsi ekuchengetedza uye ane hushamwari mwenje mhinduro kuri kuramba kuchikura, tekinoroji yeLED inotarisirwa kuita basa rinowedzera kukosha mukuumba ramangwana remwenje.
