ʻO ke kaʻina hana o nā kukui uila alakaʻi

Ma hope o nā makahiki he ʻumi o ka hoʻomaikaʻi ʻana i ke akamai, ua hoʻomaikaʻi maikaʻi ʻia ka hana ʻana o LED. ʻO nā kukui kukui, nā kukui halogen tungsten he 12-24 lumens / watt, nā kukui fluorescent 50-70 lumens / watt, a me nā kukui sodium 90-140 lumens / watt. ʻO ka hapa nui o ka hoʻohana mana e lilo i ka wela. ʻO ka maikaʻikukui LEDe hiki aku ka pono i 50-200 lumens / watt, a he monochromaticity maikaʻi kona kukui a me ke kiko kiko. Hiki iā ia ke haʻi pololei i ke kukui ʻike ʻia me ke kānana ʻole.

I kēia mau lā, ke holo wikiwiki nei nā ʻāina āpau o ka honua e hoʻomaikaʻi i ka noiʻi e pili ana i ka pono kukui LED, a e hoʻomaikaʻi maikaʻi ʻia kā lākou kukui kukui i ka wā e hiki mai ana. Me ka hoʻolaha ʻana o nā kukui kukui kiʻekiʻe o nā waihoʻoluʻu like ʻole e like me ka ʻulaʻula, melemele, a me ka ʻōmaʻomaʻo, ua hoʻololi nā LED i nā kukui incandescent kuʻuna a me nā kukui halogen tungsten.nā kukui uila. No ka mea, ʻo ka kukui i hoʻolaha ʻia e ka LED, ua paʻa loa ia i kahi kihi liʻiliʻi liʻiliʻi, ʻaʻohe mea e pono ai ka reflector, a ʻaʻole pono ka kukui i haʻi ʻia i kahi lens kala e kānana, no laila ke hana ʻia kahi lens like e ka lens convex a i ʻole kahi. ʻO ka lens Fresnel, a laila ʻae ka lens pincushion e hoʻopuehu ʻia a hoʻohuli ʻia mai ke poʻo e hoʻokō i ka hoʻopuehu māmā e koi ʻia, me kahi puʻupuʻu.
