Luminous nekubudisa - chii ichi?

Simba chiedza chinooneka, izvo zvinofungidzirwa kuti kutekenyedzwa yevanhu ziso uye kunoonekwa muzvinhu lumens - chiedza goho. Ndiro simba rinopa chero chiedza kunobva.

wavelength

The simba chechiedza panobva inopfuura nomunyika airatidza remagetsi nemafungu. Luminous nekubudisa - ndiko zvazvingava zvavo, izvo zvinopa mashoko nezvesimba sokupenya kwaibva. Energy chiedza mafungu ziso munhu anoona zvakasiyana. The wavelength pamusoro 0.55 microns ari mutema ruvara kunonzwisiswa zvakawanda akasimba kupfuura tsvuku ine kureba 0.63 microns. In kuwanda ultraviolet uye michini nemwaranzi meso edu simba.

Ndokusaka zvechadenga wavelength ari luminous zvinoyerera kuchikosha zvikuru. Tichitarisa susceptibility weziso kuburikidza Achipfupikisa wavelengths, isu tiwane normalized ukoshi. Luminous nekubudisa - ndiwo chaiwo simba wakaisvonaka simba, iyo zvinofungidzirwa nokuda kutekenyedzwa chiedza. Kusarudza kunobva chiedza simba, munhu kunoenderana simba rayo noenderana. Somuenzaniso, kana uchida kuti kutsiva incandescent mwenje pamwe akatungamirira. Muchiitiko chino, zvakakodzera recalculate chiedza goho.

How kuzviita

Luminous nekubudisa - Nde pakuderedza nenzira iyi. Panguva dvadtsativoltnoy incandescent girobhu racho zvakanga akaenzana lumens 250. Zvakangofanana luminous nekubuda kwakaita mwenje inogona watts or vaviri kana vatatu, uye fluorescent - mashanu nomwe. Saka, zvakanakira akatungamirira mwenje kunopfuura pachena.

Toti tinoda ndimo luminous nekubudisa goho 400 lumens. The filament rambi achava sorokavattnoy, fluorescent rambi inogona kubva gumi kusvika gumi watts or uye akatungamirira - zvina chete kana shanu. Kana, somuenzaniso, tinoda simba luminous okuyerera mwenje - 2500 lumens. Tungsten haagoni kuva kana ichi isingasviki dvuhsotvattnoy, fluorescent - chete makumi matanhatu kusvika masere-watt akatungamirira uye kunyange zvishoma - chete maviri nemashanu kana makumi matatu.

Ndezvipi mwenje

The kwakakura chero rambi simba chiyamuro unotaurwa watts or (W). Muupenyu hwezuva nezuva, rinoshandiswa Somuenzaniso, akatungamirira mwenje kubva imwe gumi watts or, uye nokuda panze chiedza, vanoda zvikuru simba zvikuru - kune vanopfuura zana watts or. Asi iwe unofanira kuziva kuti rambi simba chete kuratidza mwero simba rakawanda, pfungwa nesimba iye haapinduri.

Pane chinogona kuzivikanwa mumwe kana mumwe kunobva chete chairema luminous zvinoyerera riri yakasiyana zvachose ezvinhu. It hakupimwi watts or uye lumens. Kunyange kwete ose mwenje mugadziri nemazvo tsanangurai izvi zvaramba. Somuenzaniso, chaiyo iri kavha: yacho luminous okuyerera 280 lumens ive zvakatungamirira rambi simba watts or mana, zvakafanana nomunhu incandescent girobhu racho pyatidesyativattnoy. Kureva tafura: mukupera luminous zvinoyerera haana 280, uye zvose 560 CM inofanira kuva. saka sei?

Masvomhu

The chairema luminous zvinoyerera lumen aibuda iyo inongorira blackbody nzvimbo 0,5305 mm ² panguva refu tembiricha - 1773 ° C, kana ichioma Platinum, somuenzaniso. Light kusimba - arambe achirema pakati luminous zvinoyerera ari spatial mupfungwa, zvakakosha funga kuti chiedza goho correlated pamwe kwakakura yakasimba angled (yakasimba angled - ndicho chikamu nzvimbo apo vose mwaranzi wekuita). Saizvozvo; chairema luminous kuchinyanya - kwete lumens uye candela.

Chii jekeso? Izvi zvinogona kunzi pose arambe achirema luminous nekubudisa chiri chiitiko pamusoro pemvura, akaenzana nhamba yacho luminous nekubudisa kuti ukuru nokuvhenekerwa pamusoro, sezvamakaropafadzwa riri zvakaenzana anoparadzirwa. In okuvhenekesa anewo yayo chairema yakayerwa, uye haina lumen zvakare. Uye regai kunyange candela. lux ichi (lx). Izvo zvichava akaenzana imwe Suite, kana chiedza goho akaenzana imwe lumen, akagovera zvakaenderana pamusoro nzvimbo imwe mativi mita? Asi: 1 lux = 1 CM / 1M ^2.

Nokupenya uye luminosity

Light hova angava akasiyana uye svetnosti nekupenya (luminosity). Kupenya - ndiyo wakaenzana penyika arambe achirema pakati luminous zvakanyanya uye ukama aro muchadenga, projected luminous pasi ndege perpendicular zvairayirwa ichi. The chikwata kokubwinya anoonekwa kuva candela imwe mativi mita (1 CD / m ^2).

Svetnost (kana luminance) ndiro arambe achirema pamusoro luminous nekubudisa iyo inongorira Illuminated penyika. Zviri dzose akaenzana luminous nekubudisa noruremekedzo kuti nzvimbo pamusoro ichi. Luminosity, zvakare, ane yayo chikwata 1 CM / m ^2.

jekeso zvakafanana

The Utilisation chakaita kuti luminous zvinoyerera nzira kuverenga zvakafanana pakati varege kupenyerwa nokuvhenekera kwemashoko hukawanika zvose chinjikira, pasinei mhando mwenje. Chaizvoizvo Its ndechokuti coefficient rinowanikwa mukamuri rimwe, tichitarisa zvayo zvinokosha parameters uye zvivako zviri retro apedza zvinhu. Uyu zvakarurama nguva unoparadza Masvomhu havasi yakarurama kwazvo zvakakwana, asi nzira iyi zvikuru kushandiswa pana indoor chiedza kuronga.

Vhoriyamu mukamuri nguva dzose ane chokudzivirira pamusoro, izvo tiratidze chiedza nekubudisa ichibva kupi dzimwe mhando. Izvi rusvingo, sirin'i, uriri, fenicha kana midziyo yaiva mumba. pamusoro All dzakasiyana kufungisisa coefficients, ane mutengo yakakwirira zvichidzika. Ngaaverenge nhamba chiedza mano, kwete kufungisisa kunooneka chekubuda zvinogoneka chete huru nechokwadi.

Zvinofungidzirwa chikamu

First akasarudza chiedza zvinyorwa uye chiedza gadziriro, akasarudza mhando Fixtures kuti kupiwa nzvimbo - dzinogarwa kana hofisi, uye ipapo kukarukureta rinoitwa. Chinangwa chayo kuona uwandu luminaires. The kutevedzana kwezviitiko kukarukureta kunogona kuitwa maererano anorimwa:

1. Selection of okuvimba hurongwa.

2. Yokururamiswa kuti normalization muchiedza chinhu.

3. Selection of mari kupfuura kunobva chiedza.

4. Chisarudzo ndaisagona mhando rambi.

5. Evaluation of yakachengeteka chinhu uye coefficient pakati unevenness okuvhenekesa nawo.

6. Evaluation pamusoro reflectance ose hukawanika mumba.

7. kukarukureta mukamuri indekisi.

8. Kutsunga of coefficient mashandisiro chiedza.

9. pakuverenga uwandu Fixtures kuti ichapa inodiwa varege kupenyerwa nokuvhenekera kwemashoko chinhu.

10. Kuita mumwe mufananidzo nzvimbo Fixtures kushandisa uriri urongwa (tsanangurai saizi).

chiedza hurongwa

Zvakaoma zvikuru kuti overenga kushanda magetsi, nokuti kakawanda aibatanidza. Somuenzaniso, muna mukugadzira zvirimwa chimwe chete nhau yeko hakubvumidzwi nemutemo. Sarudza chiedza duku divi iri mutsauko chinhu hurongwa, kureva kuona kururama zvose ziso pamabasa, kuti akaita mumba.

Kune mitemo: basa yokutanga rechitanhatu matomu vari kunze chete kana kukabatanidzwa jekeso hurongwa. workshop ichi, zvemaziso, zvishandiso, ungano uye zvakafanana. mumaindasitiri akadai electroplating kana kurashwa chete ingashandiswa zvavo chiedza hurongwa. Saka, kusarudza maitiro uye mitemo okuvhenekesa panguva imwe chete.

normalized illuminance

Chakagadzirwa chiedza kubva quantitative uye Qualitative zviratidzi kutsunga zvichinyatso enderana pamwe zvinoshanda mirau nguva pakugadzira uye mhando basa.

Quantitative unhu chiedza akagamuchira pajinga nechimwe kushanda pasi zvichienderana okuyerera ziso mabasa, musiyano uye mamiriro chinhu ari jekeso mugadziriro. The zvinoyerera pakutsvaga kukura mumwe chinhu (mashoko), chikamu kana shoma urema pamusoro payo kuti mabasa achafanira kuziva uye kusiyanisa mabasa ayo. Yepamusoro chiedza chokupika - chiyero kudzvokora uye ripple.

Light mabhuku: zvayakanakira nezvayakaipira

Sei kuona parameters kuti pakanzi Mari-inobudirira uye panguva imwecheteyo zvakatipoteredza noushamwari chiedza kupi? On chisarudzo ingachinja zvinhu zvakawanda, zvakadai: kuronga mhinduro, mapurani, kuvaka parameters, mhepo zvakatipoteredza uye ayo ezvinhu, zvoupfumi nezvavanofunga uye Chokwadi, zvakagadzirwa. Mugadziri, afunge chiedza, nguva dzose anoenda nekuyanana, kufungisisa parameters mazhinji Masvomhu.

Somuenzaniso, imwe incandescent rambi hazvina kunyanya mari, havana yakakwirira chaizvo luminous kunyatsoshanda, anobuda chakarondedzera akavhiringika, kubasa, ivo ripise kwazvo uye nokukurumidza kukundikana. Zvisinei, mari kwavari yakaderera chaizvo, vari nyore kushandisa zvose, asi nokuti dzimba umo vanhu kugara kwenguva duku, mhuri uye zvakafanana, incandescent marambi inogona kurumbidzwa. Fluorescent chiedza goho vanewo inopfuura, upenyu hurefu, chakanakisisa ruvara shanduro, kushaya kudziyisa. Asi mugwagwa kwakadaro rambi uye zvinoda basa nyanzvi. Switchgear fluorescent mwenje zvikuru kunzwisisa, dzimwe nguva nokupenya uye ngaritinhire, uye avo kwetsvina matambudziko.
