Rere luminous - he aha te mea tenei?

Ko te mana o te marama kitea, tata nei te i te sensation o te kanohi tangata, me te te whanganga i roto i lumens - putanga marama. Ko te pūngao e homai tetahi puna marama tenei.

roangaru

Ko te pūngao o te puna marama e tika ana i te ngaru hiko itehia i. rere luminous - ko reira ratou tere, e homai mōhiohio e pā ana ki te mana o te mura o te pūtake. ngaru Energy marama kite te kanohi tangata rerekē. ka mohio te roangaru o te 0.55 microns i roto i te tae matomato te nui atu kaha atu i roto i te whero ki te roa o 0.63 microns. I roto i te whānuitanga o te radiation hihi katinga me pōkākā he kaha to tatou kanohi.

Ko Ko te aha te mea na nui nga āhuatanga o te roangaru o te rere whakaputa tūrama. Whakaaro i te susceptibility o te kanohi i Whakarāpopoto wavelengths, whiwhi tatou i te uara tonu o. rere luminous - ko te mana täkupu o te pūngao marama, tata nei te tika ki te sensation o te marama. Te kōwhiri i te puna o te pūngao marama, he tangata e hāngai ana ki tona kaha ōrite. Hei tauira, ki te hiahia koe ki te whakakapi i rama aano ki arahina. I roto i tenei take, he mea e tika ana ki te tatau anō i te putanga marama.

Me pēhea te ki te mahi i te reira

rere luminous - ko te wāhanga matua i roto i tenei ara. I te taua umanga dvadtsativoltnoy aano atu i reira rite ki te 250 lumens. Rite taea te rere luminous taua o rama arahina whakarato rua ranei e toru Watts, me kōrekoreko - rima ki te whitu. Na, nga hua o rama arahina he neke atu i te kitea.

Kia mea a e hiahia ana tatou he puna o luminous putanga rere o 400 lumens. ka sorokavattnoy te rama kakawaea, Ka taea e rama kōrekoreko kia i kotahi tekau ki te kotahi tekau ma toru Watts me LED - anake wha, e rima. Ranei, mo te tauira, e hiahia ana matou he pakaruhanga luminous kaha o rama - 2500 lumens. e kore e taea e Tungsten e i roto i tenei take iti iho i te dvuhsotvattnoy, kōrekoreko - arahina anake ono tekau ki te waru tekau-Watt, me te ara iti - anake e rua tekau-rima e toru tekau ranei.

He aha e nga rama

whanganga te rahi o tetahi tāuru mana rama i roto i Watts (W). I roto i te ora ia rā, kei te whakamahia i te reira, hei tauira, rama LED i tetahi ki te tekau Watts, a mo te rama o waho, Me nui ake kaha ratou - i reira e runga i te rau Watts. Ko me mohio koutou e te mana rama faaite anake te tere o te kohi pūngao, te ariā o te kaha kore ia e whakahoki kupu.

He taea te āhuatanga tetahi ki tetahi puna wae anake o rere luminous, i te mea he tautuhinga tino rerekē ranei. E kore te mea whanganga i roto i Watts me lumens. Ahakoa e kore nga kaihanga rama tika whakapūtā enei kōwhiringa. Hei tauira, te tapanga i runga i te tākai: te rere luminous o 280 lumens mo te mana rama arahina ki wha Watts, te ōrite o te pyatidesyativattnoy aano atu umanga. Tirohia ki te tepu: i roto i te rere luminous muri kore he 280, a kia waiho katoa 560 lm. Kia pehea te pena?

tātaitanga

Kei te lumen te kōwae o te rere luminous rere i tuku hoki wāhi blackbody o 0,5305 mm ² i te pāmahana tiketike rawa - 1773 ° C, ka whakapakeketia te reira konukawata, hei tauira. kaha te marama - te mātotoru o te rere luminous i roto i te tikanga mokowā, he mea nui ki te whakaaro pehea te putanga marama fakafekau'aki ki te nui o te koki totoka (te koki totoka - ko te wahi o te wāhi i reira ūngutungutu nga hihi katoa). Na: te kōwae o luminous - e kore lumens me kānara.

He aha te mea māramatanga? Tenei e taea te huaina i te rere luminous mata kiato e ko ohipa i runga i te mata, rite ki te ōwehenga o te rere luminous ki te rahi o te mata rauhanga, Kei te whakanoho wehea ai reira. I roto i te māramatanga hoki he ona ake wae o ine, me kore e lumen reira ano. A mahi e kore e ara kānara. Tenei lux (lx). E ka kia rite ki te kotahi huinga, ki te he rite ki te kotahi lumen te putanga marama, tohaina whakanoho iho ki runga i te rohe o tetahi mita tapawha? Ko: 1 lux = 1 lm / 1m ^2.

Tīahoaho me kiko

kia awa Light wherikotanga rerekē, me te svetnosti (kiko). Tīahoaho - Ko te ōritetanga o te kiato mata o luminous me tona hononga ki te wāhi, matapae mata luminous i runga i te waka rererangi hāngai ki tenei aronga. whakaaro te kōwae o te wherikotanga te ki kia kotahi kānara ia mita tapawha (1 cd / m ^2).

Svetnost (luminance ranei) ko te kiato o te rere luminous e tuku hoki mata rauhanga. Ko rite ki te rere luminous ki te faatura ki te rohe o tenei mata tonu te reira. Kiko, rawa, he tona wae ake ko 1 lm / m ^2.

taurite māramatanga

Ko te take whakamahi o te rere luminous ko te tikanga ki te tātai i te taurite o te māramatanga o ngā mata katoa whakapae, ahakoa o te momo o rama. Ko tōna ngako Ko e tātai te whakarea te mo ia ruma, i roto i te tirohanga o ona tawhā taketake me ngā āhuatanga o ngā rauemi faka-oti. Ko tenei e kore e tika rawa nui te tika te wa e kai ana tātai, engari Kei te whānui whakamahia tenei tikanga i whakamahere rama roto.

He tonu te rōrahi o te ruma etahi ahua o te tiaki i te mata, e ka whakaata i te rere marama e haere mai ana i te pūtake. Tenei taiepa, tuanui, papa, taonga taputapu ranei kei roto i te ruma. mata katoa i rerekē tau whakarea whakaata, ki te uara teitei iti iho ranei. Tātaihia te maha o ngā pūrere rama, e kore e tango ki pūkete he taea te rere kitea anake ki ta'epau nui.

wahi tata

tīpakohia Tuatahi puna marama, me te pūnaha rama, tīpakohia momo o turanga mo te wāhi i homai - noho tari ranei, a ka whakamana te tātai te. Ko tōna whāinga ko ki te whakatau i te maha o luminaires. Ka taea te whakamana te raupapa o tātaitanga rite ki te kaupapa:

1. Whiriwhiri o te pūnaha rama.

2. Tautikatanga o māori i roto i te marama o te ahanoa.

3. Tīpakonga o te puna tino economical o te marama.

4. Fili o te momo kouma o te rama.

5. Aromātai o te take haumaru me te tau whakarea o te pāhiwihiwi o te māramatanga reira.

6. Aromātai o reflectance o papa i roto i te ruma.

7. Tātaitanga o te taupū ruma.

8. whakatau i o te tau whakarea o te whakamahi o te marama.

9. Te tātai i te maha o nga turanga e ka whakarato i te māramatanga e hiahiatia o te ahanoa.

10. Mahi i te huahua o te wāhi o turanga te whakamahi i te mahere papa (whakapūtā rahi).

pūnaha rama

Ko reira rawa uaua ki te tātai mahi rama, no te mea kei te tino maha ngā reira. Hei tauira, i roto i te hokohoko tipu he rāhuitia kotahi anake kapinga rohe e te ture. Tīpakohia te marama o te taha iti rawa o te pūnaha ahanoa wehewehe, arā whakarite te tika o mahi ataata katoa, ki te kia whakamana i roto i te ruma.

He ture: kua kawea te mahi o te tuatahi ki te ono o nga paraire i anake, no te te pūnaha māramatanga ngā. Tenei awheawhe, aunoa, te whakatangitangi, huihui me te rite. i roto i te ahumahi pēnei i hiko makanga ranei anake e taea te tono i te pūnaha rama whānui. Na reira, whiriwhiri te pūnaha me ngā ture o te māramatanga wā kotahi.

illuminance tonu o

rama Artificial o tohu ine, me te kounga whakaritea i runga tino ki te ture hāngai, me te tonu mo te hanga, me te momo o te mahi.

āhuatanga ine o te marama riro i te raro o ia mata mahi i runga i te rere o nga mahi ataata, te rerekē, me te ahanoa whakamārama i roto i te pūnaha māramatanga rānei. takoto ana te rere e te rahi o te ahanoa kotahi (te kōrero), wahi ranei koha iti i runga i te reira e mahi, ka whai ki te kitea me te wehewehe i waenganui i ona mahi. High-kounga mahi rama - he mehua o te kōnakonako me pōkare.

puna marama: pai me ngā raruraru

Me pēhea te ki te whakatau i te tawhā mō te tīpako-utu whai hua, me te i te wa taua taiao puna te marama hoa? I kia pā te whakatau maha ngā āhuatanga, pērā i: whakamahere otinga, hoahoanga, tawhā hanga, taiao rangi me ona huru, whakaaro ōhanga me te, o te akoranga, hoahoa. Designer, hoahoa rama, haere tonu ki te ngāwari, tango ki pūkete maha tawhā i roto i te tātai.

Hei tauira, e kore te mea economical rawa he rama aano atu, e kore e ratou pai luminous tiketike rawa, tukunga tūāwhiorangi mio'i, i mahi, whiwhi ratou rawa wera, me te hohoro kore. Heoi, ko te tino iti te utu o ratou, he māmā ake ki te whakamahi i katoa ratou, engari no te mea hoki ruma noho poto wahi iwi, whare me te rite, e taea te tūtohutia rama aano atu. hoki i te, te ora roa pai, tāhuahua tae pai, te kore o te whakawera putanga marama antibody. Ko rama taua ara me te rapu utu ngā tohunga mahi. Ko Switchgear rama kōrekoreko rawa matatini, ratou ētahi wā flash me haruru, me o ratou tikanga raruraru.
