LED Ubushyuhe
Kubera ko urumuri rwinshi rutangwa nisoko yumucyo hamwe hamwe rwitwa urumuri rwera, ubushyuhe bwameza yibara cyangwa ubushyuhe bujyanye nubushyuhe bwamabara yumucyo bikoreshwa mukugereranya urwego ibara ryumucyo ryera ugereranije numucyo. ibara ryimikorere yumucyo. Dukurikije inyigisho ya Max Planck, umubiri wumukara usanzwe winjiza neza na radioactivite urashyuha, kandi ubushyuhe bugenda bwiyongera buhoro buhoro, kandi urumuri rugahinduka; Umubiri wumukara kumurongo wa CIE yerekana inzira yumubiri wumukara umutuku-orange-umuhondo-umuhondo-umweru-wera-ubururu-bwera. Ubushyuhe umubiri wumukara ushyutswe kimwe cyangwa hafi yumucyo bisobanurwa nkubushyuhe bwamabara bufitanye isano nisoko yumucyo, ibyo bita ubushyuhe bwuzuye K (Kelvin cyangwa Kelvin) (K = ° C + 273.15) . Kubwibyo, iyo umubiri wumukara ushyutswe ibara ritukura, ubushyuhe buri hafi 527 ° C, ni ukuvuga 800 K, nubundi bushyuhe bugira ingaruka kumihindagurikire yamabara.
Kurenza ibara ryoroheje nubururu, nubushyuhe bwamabara; ibara ritukura ni munsi yubushyuhe bwibara. Ibara ryumucyo kumunsi naryo rihinduka hamwe nigihe: iminota 40 nyuma yizuba rirashe, ibara ryumucyo ni umuhondo, ubushyuhe bwamabara ni 3.000K; izuba rya sasita ryera, rikazamuka rigera kuri 4.800-5,800K; Saa sita zuzuye ibicu, ni 6.500K; mbere yuko izuba rirenga, ibara ritukura kandi ubushyuhe bwamabara bugabanuka kugera kuri 2200K. Ubushyuhe bwamabara afitanye isano nandi masoko yumucyo, kubera ko ubushyuhe bwamabara bufitanye isano mubyukuri imirasire yumubiri wumukara wegera ibara ryumucyo, agaciro ko gusuzuma ibara ryumucyo ntabwo ari ibara ryukuri, bityo amasoko abiri yumucyo afite kimwe ibara ryubushuhe agaciro, Harashobora kuba hari itandukaniro mubigaragara byamabara yumucyo. Ubushyuhe bwamabara bwonyine ntibushobora kumva ibara ryerekana ubushobozi bwurumuri rwikintu, cyangwa uburyo ibara ryikintu ryororoka munsi yumucyo.
Ubushyuhe bwamabara ajyanye nibidukikije bitanga urumuri rutandukanye
Umunsi w'igicu 6500-7500k
Imirasire y'izuba saa sita 5500K
Itara ryicyuma cya 4000-4600K
Imirasire y'izuba nyuma ya saa sita 4000K
Amatara akonje akonje 4000-5000K
Itara ryinshi rya mercure 3450-3750K
Itara ryamabara ashyushye 2500-3000K
Itara rya Halogen 3000K
Itara rya buji 2000K
Ubushyuhe bwamabara yumucyo uratandukanye kandi ibara ryurumuri riratandukanye. Ubushyuhe bwamabara buri munsi ya 3300K, hari ikirere gihamye, kumva ubushyuhe; ubushyuhe bwamabara ni 3000--5000K kubushyuhe bwo hagati, kandi hariho ibyiyumvo; ubushyuhe bwamabara bufite ubukonje hejuru ya 5000K. Amabara atandukanye yumucyo aturuka kumucyo atandukanye agize ibidukikije byiza.
Ubushyuhe bwamabara nijisho ryumuntu kumva kumurika cyangwa kumurika byera. Ibi ni ibyiyumvo bya fiziki. Ibintu bigoye kandi bigoye bya physiologiya na psychologiya nabyo biratandukanye kumuntu. Ubushyuhe bwamabara burashobora guhinduka muburyo bwumuntu kuri TV (illuminator) cyangwa gufotora (reflektor). Kurugero, dukoresha itara ryubushyuhe bwa 3200K (3200K) mugufotora, ariko twongeyeho akayunguruzo gatukura kumurongo. Gushungura ukoresheje itara rito ritukura bituma ifoto igaragara munsi yubushyuhe bwamabara; impamvu imwe, turashobora kandi kugabanya umutuku muto kuri TV (ariko kugabanya cyane nabyo bizagira ingaruka kumikorere isanzwe itukura) kugirango ishusho igaragare neza.
Ibyifuzo byubushyuhe bwamabara bigenwa nabantu. Ibi bifitanye isano nubuzima bwa buri munsi tubona. Kurugero, mubantu begereye ekwateri, impuzandengo yubushyuhe bwibara igaragara burimunsi ni 11000K (8000K (bwije) ~ 17000K (saa sita)). Nkunda rero ubushyuhe bwo hejuru bwamabara (bisa nkaho ari ibintu bifatika). Ibinyuranye, abantu bafite uburebure buri hejuru (impuzandengo yubushyuhe bwamabara agera kuri 6000K) bahitamo ubushyuhe buke bwamabara (5600K cyangwa 6500K), bivuze ko niba ukoresheje televiziyo yo hejuru yubushyuhe bwo kwerekana ibara rya Arctique, bisa nkicyatsi kibisi; muburyo bunyuranye, niba ukoresheje ubushyuhe buke bwa TV kugirango ubone uburyo bwa subtropical, uzumva umutuku muto.
Nigute ubushyuhe bwamabara ya TV cyangwa kwerekana ecran bisobanurwa? Kubera ko impuzandengo yubushyuhe bwibara mubushinwa bugera kuri 8000K kugeza 9500K mumwaka wose, televiziyo ikora progaramu ishingiye kubushyuhe bwamabara yabarebaga 9300K. Ariko, kubera ko ubushyuhe bwamabara muburayi na Amerika butandukanye nubwacu, impuzandengo y'ibara ryumwaka wose ni 6000K. Kubwibyo, iyo turebye ziriya firime zamahanga, tuzasanga 5600K ~ 6500K aribwo bubereye kureba. Nibyo, iri tandukaniro rituma twumva ko iyo tubonye ecran ya mudasobwa cyangwa TV muburayi na Amerika, twumva ko ubushyuhe bwamabara butukura kandi bushyushye, kandi bimwe ntibikwiye.
