Nā kuhikuhi kuhikuhi

I kēia manawa, ke pani ʻia nei nā ʻōpuʻu kukui e nā LED light emitting diodes. ʻOi aku ka maikaʻi a ʻoi aku ka māmā o ka māmā ma mua o nā ʻōpuʻu kukui maʻamau.

I kēia manawa, ke pani ʻia nei nā ʻōpuʻu kukui e nā LED light emitting diodes. ʻOi aku ka maikaʻi a ʻoi aku ka māmā o ka māmā ma mua o nā ʻōpuʻu kukui maʻamau.

 

He holomua nā LED i nā kukui kaʻa, e like me ka uwila uila i ka hoʻomaka ʻana o ke kenekulia 20. Ua hoʻohana mua ʻia nā kukui i nā kukui a me nā kukui hope. Ua hōʻailona ʻia ka hoʻololi ʻana i ke kuhikuhi e nā levers sliding i hoʻokomo ʻia i ka XNUMXs.

I ka piʻi nui ʻana o ke kaʻa ma nā kūlanakauhale i nā makahiki 20, ua kau ʻia nā kānāwai i kēlā me kēia ʻāina e pale i ka haunaele. Ma Kelemānia, ua koi ʻia ka mea hoʻokele e hōʻailona i kona manaʻo e hoʻololi i ka ʻaoʻao a me ke kaʻa, i hiki i nā kaʻa ma hope ke hana koke. Ma Polani, ua ʻike ʻia nā ʻanuʻu mua i ka hoʻokumu ʻana i nā lula kaʻa i ka makahiki 1921, i ka wā i hoʻopuka ʻia ai kahi hoʻonohonoho o nā lula maʻamau no ka neʻe ʻana o nā kaʻa ma nā alanui ākea.

Ua hōʻike ʻia nā hōʻailona huli e kōkua nui i ka hahai ʻana i nā lula kaʻa a, ʻoi aku ka mea nui, i ka pale ʻana i nā hui ʻana he nui. Ma hope o ke kaomi ʻana i ke pihi pili, huki ka electromagnet i ka lever kuhikuhi kuhikuhi ma kahi o 20 knm ka lōʻihi mai ka hale, e hōʻailona ana i ka makemake e hoʻololi i ke ala. Ma hope mai, ua hoʻomālamalama ʻia ka lever index, i hāʻawi iā ia me ka ʻike maikaʻi aʻe.

Ua hoʻohana nā mea hana kaʻa i nā mea hana i hana ʻia e nā poʻe ʻekolu. I Kelemānia, ua kaulana ka hōʻailona huli mai Bosch, i hoʻolauna ʻia ma ka mākeke ma 1928; ma USA, kaulana nā ʻoihana Delco. Ua hoʻololi wale ʻia nā hōʻailona kuhikuhi electromagnetic e nā hōʻailona huli i ʻike ʻia i nā makahiki 50.
