Arahina Thyristor. Āhuatanga me parau tumu o te mahi

Thyristor LED - ko te rerekē nui ki te taipitopito ngā tenei ra, e kua whakamahia i roto i te hanga o ngā pūrere rama tenei. Painga o arahina: pikinga i roto i te mahi, iti kohi mana me āhuatanga iti.

Ko te parau tumu o te mahi o te arahina

Ko te take i te tukanga luminescence ko te tauhono o rua pai whakatupato me matūriki tōraro i ako i roto i te rohe ph-whakawhitinga. Tenei rohe ko te atanga o rauemi e rua (Semiconductors) ki rerekē te kaha kawe ia o nāianei. Hei waihanga i tētahi mura kanapa o te hanganga multilayer o te maramara arahina. Ka taea te nui haere tona tiahotanga mā te tono i te mānukanuka kaha, engari ki te uara nui o te nāianei ngōhiko e taea kore. Ka taea te whakaritea tiaho arahina i te aronga o te whakaiti i. Ko te tino māmā tona hanganga, engari i te wa ano, e kore e te nuinga o ngā kaiwhakanao whakaatu te ngaro o te hanga o ona hua.

Ki te rā, hou tiristotny LED rawa hua, no te mea ona awhe pai i 60 ki te 70%. Ki te whakarite tatou i te rama aano atu (te tōtika o e 5-7 anake%) ki te arahina, te muri pai atu i toharite tekau wā. Ko te wā o te mahi i kīia o ngā pūrere rama e whakamahi ngōhiko thyristor marama-emitting, he tekau tau o te marama tonu. penapena pūngao ka whakamahi i LED, rite whakaritea ki te LDR he āhua 50%, whakaritea ki te aano atu - 85%.

Ko te putanga marama o te p hou taea whakataetae ki Ipf ko HPS (ko DNaZ). He rite ki te 150 lm / W. tenei ahua Ko te wā payback o topuku arahina - 2-3 tau. I muri, te kotahi tekau nga tau e toe ana, e whakaora koe 85% o te hiko pau ia marama.

LED. āhuatanga o

Arahina, e kore he analogues iho āhuatanga, i nga painga e whai ake nei:

• i roto i te hanga o LEDs e whakamahia karaihe, na maramarama rama o tenei momo i mauroa nui, wiri resistance me te tika;
• Arahina ātete ki rerekē ngaohiko me te pau anake 0.4-0.6 A;
• whakahaere tōtika Thyristor LED i roto i ngā āhuatanga tino, ara i pāmahana tino iti.

Hei tīmata i te arahina, titau tino utu piriti ngōhiko, meinga te utu o te rama mua i tino overpriced. faatiti'aifarohia kaiwhakanao tenei raruraru. Kua hoahoa schematic kua puta ke, me te utu o dimmers triac thyristor kua tono. Ko te hua ko te pūrere arā, o thyristors rua hono i roto i whakarara, te tikanga te counter. Nā ki tenei auaha, he ngaro te hiahia mo te piriti ngōhiko tenei ra. arahina tenei whakatau ki ngā hua iti me tino nui haere te taumata haumarutanga me te kounga o te taonga i runga i te pūtake o te thyristors.

Kei te whānui Thyristor LED whakamahia i roto i te hanga o ngā pūrere rama. Ko tōna ora ratonga roa, tika me te māmā ahuareka ana kiritaki, kia rite ki chandeliers me ētahi atu pūrere ki arahina-māramatanga he economical kore anake, engari ano hoki titiro tino ataahua.
