He aha ka hopena o ka hana wela kiʻekiʻe o ka hōʻike LED

He aha ka hopena o ka hana wela kiʻekiʻe o ka hōʻike LED

I kēia lā, ke hoʻohana nui ʻia ka pale hōʻike LED, pono mākou e hoʻomaopopo i ka manaʻo maʻamau o ka mālama.Inā he hōʻike LED i loko a i waho paha, hana ʻia ka wela i ka wā o ka hana.No laila, he hopena paha ka hana wela kiʻekiʻe o ka hōʻike LED?

ʻO ka ʻōlelo maʻamau, he haʻahaʻa haʻahaʻa haʻahaʻa ka hōʻike LED i loko, no laila he emi ka wela, no laila hoʻokuʻu maoli ka wela.Eia nō naʻe, ʻo ka hōʻike LED waho he ʻōlinolino kiʻekiʻe a hoʻohua i ka wela nui, pono e hoʻomaha ʻia e nā air conditioners a i ʻole axial fans.No ka mea he huahana uila ia, e hoʻopilikia ka piʻi ʻana o ka mahana i kona ola lawelawe.

He aha ka hopena o ka hana wela kiʻekiʻe o ka hōʻike LED

1. Inā ʻoi aku ka mahana hana o ka hōʻike LED ma mua o ka wela o ka haʻahaʻa o ka chip, e hoʻemi ʻia ka pono kukui o ka hōʻike LED, e ʻike ʻia ka emi ʻana o ka māmā, a hiki mai ka pōʻino.ʻO ka wela nui e hoʻopili i ka attenuation o ke kukui o ka pale LED, a aia ka attenuation māmā.ʻO ia hoʻi, i ka hala ʻana o ka manawa, e emi mālie ana ka ʻōlinolino a pio.ʻO ka wela kiʻekiʻe ke kumu nui o ka pohō māmā a me ka pōkole o ke ola hōʻike.

2. ʻO ka piʻi ʻana o ka mahana e hoʻemi i ka pono luminous o ka pale LED.I ka piʻi ʻana o ka mahana, piʻi ka manaʻo o nā electrons a me nā lua, e emi ana ka ʻāpana o ka hui, a emi ka neʻe ʻana o ka electron.Ke piʻi ka mahana, hoʻololi ka piko polū o ka puʻupuʻu i ke ala hawewe lōʻihi, e hoʻemi ana ka lōʻihi o ka hawewe o ka puʻupuʻu a me ka lōʻihi o ka phosphor, a me ka hoʻemi ʻana o ka hoʻomaʻamaʻa māmā ma waho o ka pale keʻokeʻo LED.Ke piʻi aʻe ka mahana, e emi ana ka nui o ka phosphor, e emi ana ka luminosity, a e emi ana ka pono o ka unuhi ʻana o nā kukui waho o ka pale LED.
