Muchokwadi, parizvino 18% yemutengo wemagetsi bhiri yedu inoshandiswa pakuvheneka mudzimba uye inopfuura 30% mumahofisi. Kana isu tikasarudza mhando ye magetsi akakwana pamashandisirwo ega ega, tichawana ponesa pakati pe20% ne80% simba.
Kuchengetedza tinoda kushandisa Simba rekuchengetedza mabhalibhu, uye tinozvipatsanura izvi zvinoenderana nezvavanazvo kupenya, kuburikidza neyuniti yechiyero "lumens"Kana kuti"lumens", Iyo inoratidza huwandu hwechiedza chakaburitswa.
Asi, mabhanditi emagetsi (yekare) chiyero chayo yaive iyo Watts (W), izvi zvinoratidza kuti yakawanda sei magetsi kupedza.
Chinyorwa chinotevera chinoedza kutsanangura maitiro ekuverenga maLumens emabhuru.
Chii chinonzi Lumen? uye kuti ungaiverenga sei
Mubvunzo wekutanga watinofanira kuzvibvunza ndewekuzvibvunza isu kuti chii maLumens?
- Iwo ma lumens, ndicho chikamu cheInternational System of Measurements kuyera kubwinya kunoyerera, chiyero chesimba rinovhenekera. yakaburitswa nekwaibva, mune ino girobhu racho.
- Kuziva lumens iyo inogadzira girobhu re LED Iko kune fomula: Real lumens = Kwete yewatts x 70, 70 iri avhareji kukosha iyo yatinowana mumazhinji mababu. Zvinoreva, 12W akatungamirira girobhu racho yaizopa kuburitswa kwechiedza che840 lm. Izvo zvakanyanya kana zvishoma ndizvo zvinogadzira a 60W incandescent girobhu racho. Sezvauri kuona, nekugadzira mwenje wakaenzana wechiedza, tinochengetedza 48w yega yega girobhuvhuru ratinodzora.
Nzvimbo dzakabatidzwa zvakanaka
Kugadzirisa nyaradzo yemakamuri akasiyana eimba, ese anofanirwa kuve akajeka mwenje. Uye zvakakosha kuziva izvozvo "Zvakanaka mwenje" zvinoreva kuti nzvimbo yega yega inofanirwa kuve nemwenje wakaringana: kana kuwanda kana kushomeka pane zvakafanira. Kana huwandu hwechiedza husina kukwana, maziso anomanikidzwa kushanda zvakanyanyisa, uye izvi zvinotungamira mukuneta kwekuona, izvo zvinokonzeresa zviratidzo zvakaita sekutemwa nemusoro, kutsamwiswa kwemaziso nekurumwa, kurema mumaziso, nezvimwe.
Yakakurudzirwa mwenje yemakamuri mumba
Kana yuniti yanyatsotsanangurwa, tinogona kuyedza kuverenga ingani magetsi ekuchengetedza magetsi mababu anodikanwa yenzvimbo yakatarwa, inogona kuve chero chikamu cheimba.
Kuziva chii Chikamu chemwenje inokurudzirwa, isu tinofanirwa kutarisa kune iyo lux. Ichi ndicho Chidimbu chekuvhenekerwa kweInternational System, yechiratidzo lx, iyo yakaenzana nekuvhenekera kwenzvimbo iyo inowanzo neyakaenzana inogamuchira kubwinya kunoyerera kwe1 lumen pamamita mita.
Izvi zvinoreva kuti, kana imba yakavhenekerwa negirobhu 150 lumen, uye nzvimbo yemakamuri iri gumi mativi metres, mwenje wekuvhenekesa uchave 10 lx.
Zvichienderana nechikamu ichi, pane zvinokurudzirwa zviyero zveyero yemwenje mumamiriro epamba, zvinoenderana nezvinodiwa nenzvimbo yega yega mumba.
- Imba yekicheni: kurudziro yekuvhenekesa kwakawanda iri pakati pe200 uye 300 lx, kunyangwe yenzvimbo yebasa chaiyo (panotemwa chikafu nekugadzirwa) inokwira kusvika pa500 lx.
- Dzimba dzekurara: yevakuru, kwete akakwirisa mwero inokurudzirwa kune yakazara mwenje, pakati pe50 ne150 lx. Asi pamusoro pemibhedha, kunyanya pakuverenga ipapo, mwenje wakatarisana unosvika 500 lx inokurudzirwa. Mumakamuri evana zvinokurudzirwa mwenje zvishoma zvishoma (150 lx) uye anenge mazana matatu lx kana paine chiitiko uye nemitambo nzvimbo.
- Imba yekugara: Mheni yakajairika inogona kusiyanisa pakati pezana ne100 lx, kunyangwe yekutarisa terevhizheni zvinokurudzirwa kuti iwe udzike pasi kutenderedza 300 lx uye nekuverenga, semumba yekurara, kuvhenekera 500 lx yakatarisa.
- Bhati: haudi mwenje wakawandisa, anenge zana lx akakwana, kunze kwenzvimbo yegirazi, yekuveura ndebvu, kuisa make-up kana kuzama bvudzi rako: kwakatenderedza 500 lx inokurudzirwawo ipapo.
- Masitepisi, makoridho uye dzimwe nzvimbo dzekufamba kana kushoma kushandisa: iyo yakanaka ndeyemwenje wakajairika we100 lx.
Tafura yeZvakaenzana
Kufambisa switching kubva watts kuenda lumens, chinova chinhu chitsva, pane tafura inoita kuti zvive nyore kuverenga nekukurumidza watts kune lumens (yakaderera mutengo mababu):
