\u0160is ir otrais no trim rakstiem par galvenaj\u0101m BS5489 izmai\u0146\u0101m, kas public\u0113tas 2020. gada s\u0101kum\u0101. Tas, ka BS5489 tagad kategoriski apstiprina, ka absol\u016bt\u0101 un relat\u012bv\u0101 fotometrija dod vien\u0101du rezult\u0101tu, tika uzskat\u012bts par b\u016btisku preciz\u0113jumu\u00a0\u00a0<\/span><\/h6>\n

K\u0101p\u0113c preciz\u0113jums par fotometriju bija svar\u012bgs?<\/strong><\/h4>\n

Tehnisk\u0101 nozar\u0113, kur specifik\u0101cijas un dati ir iz\u0161\u0137iro\u0161i, bija svar\u012bgi gal\u012bgi atrisin\u0101t str\u012bdu par absol\u016bto un relat\u012bvo fotometriju. Jaunaj\u0101 dokument\u0101 skaidri izkl\u0101st\u012bts, k\u0101 darbojas abi fotometrijas veidi, un apstiprin\u0101ts, ka tie dod vien\u0101du rezult\u0101tu.<\/p>\n

Ir \u013coti svar\u012bgi, lai nozare izprastu \u0161\u0101das tehniskas nianses. Klientiem j\u0101sa\u0146em \u013coti skaidri nor\u0101d\u012bjumi, lai jebk\u0101di m\u012bti vai mald\u012bgi priek\u0161stati, kas s\u0101k izplat\u012bties, vienk\u0101r\u0161i nek\u013c\u016btu par visp\u0101rpie\u0146emtu paties\u012bbu.<\/p>\n

LED arvien pla\u0161\u0101k ievie\u0161ot, datiem j\u0101balst\u0101s faktos. Ir viegli iekrist slazd\u0101 un pie\u0146emt, ka absol\u016bt\u0101 fotometrija noteikti ir lab\u0101ka, jo t\u0101 ir \u201eabsol\u016bta\u201d. Protams, tas izklaus\u0101s lab\u0101k, bet paties\u012bb\u0101 LED tehnolo\u0123ija nav tik vienk\u0101r\u0161a, t\u0101p\u0113c, j\u0101, manupr\u0101t, ir labi, ka nozare ofici\u0101li ir izbeigusi izplat\u012btu mald\u012bgu priek\u0161statu.<\/p>\n

Mums k\u0101 uz\u0146\u0113mumam bija \u013coti iepriecino\u0161i redz\u0113t, ka \u0161\u012b koncepcija, ko INDO jau ilgu laiku ir aizst\u0101v\u0113jis,<\/a> tagad ir ofici\u0101li apstiprin\u0101ta.<\/p>\n

Ko saka jaunie standarti?<\/strong><\/h4>\n

Standarta fotometrijas sada\u013cas s\u0101kum\u0101 ir skaidri noteikts:<\/p>\n

…Apgaismojuma projekt\u0113\u0161anu var veikt, izmantojot absol\u016bto vai relat\u012bvo fotometriju… ab\u0101m ir priek\u0161roc\u012bbas un tr\u016bkumi, un nevienai no t\u0101m netiek dota priek\u0161roka, jo ar ab\u0101m metod\u0113m sagaid\u0101ms vien\u0101ds rezult\u0101ts<\/p><\/blockquote>\n

Tas tie\u0161i atsp\u0113ko nozar\u0113 izplat\u012bto mald\u012bgo inform\u0101ciju<\/p>\n

Tiek izdotas specifik\u0101cijas, kur\u0101s noteikts, ka iesniegtajai fotometrijai j\u0101b\u016bt absol\u016btai. Tom\u0113r, t\u0101 k\u0101 fotometriju var m\u0113r\u012bt divos veidos (absol\u016bt\u0101 un relat\u012bv\u0101), ja m\u0113r\u012bjumi veikti pareizi, rezult\u0101ts b\u016bs vien\u0101ds gan klienta apgaismojuma apr\u0113\u0137inu programmat\u016br\u0101, gan dab\u0101 p\u0113c uzst\u0101d\u012b\u0161anas.<\/p>\n

Protams, ra\u017eot\u0101jiem nav probl\u0113mu sagatavot absol\u016bto fotometriju: m\u0113s to varam un dar\u012bsim, ta\u010du ir b\u016btiski saprast, ka \u201efotometriskajam failam, ko izmanto gaismas avota veiktsp\u0113jas noteik\u0161anai, prec\u012bzi j\u0101atspogu\u013co gaismek\u013ci\u201d. Atkal: nav noz\u012bmes, kuru m\u0113r\u012bjumu izmanto, ja vien tas ir prec\u012bzs. Un tas ir galvenais.<\/strong><\/p>\n

Vair\u0101k par to lasiet m\u016bsu bloga rakst\u0101 par absol\u016bto un relat\u012bvo fotometriju<\/a> (T\u0101 joproj\u0101m ir viena no m\u016bsu apmekl\u0113t\u0101kaj\u0101m t\u012bmek\u013ca lap\u0101m!).<\/p>\n

Paties\u012bb\u0101 viss, kas saist\u012bts ar LED fotometriju, jebkur\u0101 gad\u012bjum\u0101 ir sare\u017e\u0123\u012bt\u0101ks.<\/h4>\n

Pirms LED, kad bija spuld\u017eu fotometrija, konkr\u0113tai spuldzei bija gaismas pl\u016bsmas v\u0113rt\u012bba, kas faktiski bija apkopota, test\u0113jot lielu skaitu spuld\u017eu.<\/p>\n

Piem\u0113ram, kad teic\u0101m, ka Cosmopolis spuldzei ir 16,5 t\u016bkst. l\u016bmenu, tas bija t\u0101p\u0113c, ka \u0161im spuldzes tipam bija veikti vair\u0101ki m\u0113r\u012bjumi un dati apkopoti vien\u0101 gaismas pl\u016bsmas v\u0113rt\u012bb\u0101. Tad var\u0113ja veikt fotometriju\u2026 izmantoja \u0161os spuldzes datus fotometrij\u0101, un gaismek\u013ca lietder\u012bbas koeficients (LOR) par\u0101d\u012bja, k\u0101da ir gaismek\u013ca faktisk\u0101 gaismas pl\u016bsma.<\/p>\n

M\u016bsdien\u0101s ra\u017eot\u0101ji pa\u0146em vair\u0101kas LED plates, t\u0101s test\u0113 un m\u0113ra gaismas pl\u016bsmu. Neizb\u0113gami tiek izv\u0113l\u0113ts lab\u0101kais rezult\u0101ts, tas ar liel\u0101ko gaismas pl\u016bsmu, un tie\u0161i \u0161is skaitlis tiek nor\u0101d\u012bts. Paties\u012bb\u0101, ja izmanto absol\u016bto fotometriju, vajadz\u0113tu b\u016bt pien\u0101kumam test\u0113t vismaz 10 modu\u013cus katram variantam un \u0146emt to gaismas pl\u016bsmas vid\u0113jo v\u0113rt\u012bbu.<\/p>\n

Liel\u0101kajai da\u013cai cilv\u0113ku ar spuldzi bija \u0113rti, jo bija \u013coti viegli saprast, k\u0101 t\u0101 darbojas. Nebija noz\u012bmes, no k\u0101 pirka 250 vatu augstspiediena n\u0101trija (SON) lampu; t\u0101s visas bija vien\u0101das, un bija skaidrs, ko sa\u0146em. Ta\u010du tagad main\u012bgo ir \u013coti daudz. Pat ja visi izmantotu vienas un t\u0101s pa\u0161as LED mikrosh\u0113mas, vien\u0101dojum\u0101 ir daudz citu faktoru, un klienti ieg\u016bst at\u0161\u0137ir\u012bgus rezult\u0101tus.<\/p>\n

\"\"<\/a><\/p>\n

Ir saprotams, ka ar absol\u016bto fotometriju cilv\u0113ki j\u016btas dro\u0161\u0101k, jo uzskata, ka t\u0101 ir prec\u012bz\u0101ka un tuv\u0101ka tradicion\u0101lajam gaismas avotu v\u0113rt\u0113\u0161anas veidam.<\/p>\n

T\u0101tad, lai gan LED tehnolo\u0123ija ir main\u012bjusi visu, liel\u0101k\u0101 da\u013ca cilv\u0113ku joproj\u0101m labpr\u0101t mekl\u0113 atbilst\u012bbas vecaj\u0101m spuldz\u0113m. Vi\u0146i izmanto vec\u0101s tehnolo\u0123ijas pieredzi, lai saprastu jauno, un diem\u017e\u0113l tas nedod prec\u012bzus rezult\u0101tus. Klientiem vajadz\u012bgi LED eksperti un ra\u017eot\u0101ji, kas sniedz padomu un pal\u012bdz orient\u0113ties jauno produktu sare\u017e\u0123\u012bt\u012bb\u0101, atkl\u0101ti, god\u012bgi un skaidri run\u0101jot par datiem.<\/p>\n

Tas ir m\u0101c\u012b\u0161an\u0101s process, un tie\u0161i t\u0101p\u0113c \u0161ie standarti ir tik svar\u012bgi: tie pal\u012bdz mums visiem saprast, k\u0101 labi paveikt savu darbu un piem\u0113rot pareizo pieeju m\u016bsdienu tehnolo\u0123ij\u0101m.<\/p>\n
