ʻO nā pilikia maʻamau me nā Diodes ʻālohilohi

Ua hālāwai ʻoe i nā pilikia he nui ʻaʻole maopopo, a he aha nā pilikia maʻamau? No ke aha ʻaʻole hiki ke hoʻohana ʻia ka diode māmā i overvoltage a i ʻole overcurrent e hoʻohana i ke kukui keʻokeʻo LED? ʻO ka waiho wale ʻana, wehewehe ʻia e ka LED kukui keʻokeʻo 5mm maʻamau. ʻO ka nui o kāna voli hana maʻamau i loko o 3.0-3.5V, a ʻo ka hana maʻamau ʻo 20mA 20mA. Eia naʻe, manaʻo hewa ka poʻe he ʻoi aku ka mālamalama o ka hoʻohana ʻana i nā kukui keʻokeʻo me ka over-voltage a i ʻole overcurrent, a ʻo ka hopena hoʻāʻo maoli ma hope o 15mA, piʻi nui ka optical flux. Ma hope o 20mA, aneane ʻaʻohe ʻike. Akā, ua maopopo ke kuni. Aia kekahi ho'āʻo o ke ola: 20mA ua hana no hoʻokahi mahina, a ʻo ka attenuation he 5% wale nō. I kēia manawa aia he 95% optical flux. Ke hana ʻo 30mA a hiki i 19 mau lā, ʻo 50% wale nō ka nui o ke kukui. Hiki ke noʻonoʻo ʻia he LED kukui keʻokeʻo hiki ke hana i nā hola 100,000 ma lalo o nā kūlana maʻamau e hoʻohana ʻia i nā au nui, me ke ola o 600 mau hola wale nō! Hiki ke hoʻohana ʻia nā LED ma mua o 50,000 mau hola ma nā wehewehe ākea, a ke ʻōlelo nei kekahi mau mea hana e hiki i kāna LED ke hana ma kahi o 100,000 mau hola, akā ʻaʻole kēia e hōʻoiaʻiʻo e hiki ke hoʻohana ʻia nā huahana LED no ka lōʻihi. Hiki ke maʻalahi ka hana hewa a me ke kaʻina hana “E luku ”ʻO nā LED, nā LED e hoʻohaʻahaʻa mālie i ka manawa. Hōʻike kekahi mau wānana e hiki ke mālama i nā LED kiʻekiʻe ma mua o 60% o ka mālamalama kukui mua ma hope o 50,000 mau hola o ka hana mau. No ka hoʻolōʻihi i ke ola o LED, pono e hōʻemi a hoʻopau loa i ka ikehu wela i hana ʻia e ka chip LED. ʻO ka ikehu wela ke kumu nui e pau ai ka hana ʻana o LED. Ua wehewehe ʻia kēia no ka hoʻohana ʻana i nā diodes māmā. No ka 'ike hou aku, e 'olu'olu e leka uila i ka 'ōlelo kūkākūkā o nā mea kū'ai aku.
