ʻO ke kumu keleawe hoʻoluʻu LED

Me ka hoʻomohala wikiwiki ʻana o nā kukui LED i kēia lā, ʻo ka dissipation wela ka pilikia nui o ke kukui LED.Pehea e hiki ai iā mākou ke hoʻoponopono i ka pilikia o ka hoʻoheheʻe wela LED?I kēia lā e kamaʻilio mākou e pili ana i ka pilikia o ka LED heat dissipation copper substrate no ka LED heat dissipation.

ʻO ka ʻoihana LED kekahi o nā ʻoihana i huki nui ʻia i nā makahiki i hala.A hiki i kēia manawa, loaʻa nā huahana LED i nā pono o ka mālama ʻana i ka ikehu, mālama mana, kiʻekiʻe kiʻekiʻe, ka manawa pane wikiwiki, ka lōʻihi o ke ola ʻana, ka mercury-free, a me nā pono palekana kaiapuni.Eia nō naʻe, ma kahi o 15% o ka mana hoʻokomo o nā huahana LED mana kiʻekiʻe hiki ke hoʻololi i ka mālamalama, a ʻo ke koena 85% o ka ikehu uila e hoʻololi ʻia i ka ikehu wela.

ʻO ka ʻōlelo maʻamau, inā ʻaʻole hiki ke hoʻokuʻu ʻia ka ikehu wela i hana ʻia e ke kukui LED, ʻoi aku ka kiʻekiʻe o ka mahana o ka hui ʻana o LED, e hoʻopilikia ai i ka pōʻai ola o ka huahana, ka pono luminous, a me ke kūpaʻa.ʻO ka pilina ma waena o LED junction temperature, luminous efficiency, a me ka pilina ola.

I ka hoʻolālā hoʻoheheʻe ʻana o ka wela LED, ʻo ka mea nui ka hoʻemi pono ʻana i ka pale wela mai ka papa kukui-emitting o ka chip i ke kaiapuni.No laila, pono loa e koho i kahi substrate hoʻoheheʻe wela kūpono a me nā mea pili.

Lawe ʻia ka wela wela o nā kukui a me nā mea hana.ʻO ka hoʻokuʻu ʻana o ka wela e hilinaʻi nui ʻia i ka wahi, a hiki ke koho ʻia ka substrate keleawe me ka conductivity thermal kiʻekiʻe no ka concentrated heat conduction.
