E ai ki te taumata o te ngaohiko o te hiko, ka taea te wehe nga taraiwa LED ki nga waahanga e toru: ko tetahi e whakahaerehia ana e nga papahiko, e whakamahia ana mo nga hua hiko kawe, e whakahaere ana i nga LED ma iti me te kaha-nui; ko tetahi e whakahaerehia ana e te ngaohiko nui ake i te 5, a
1. te whakaū i te Te otinga whakaoho pūhiko
Ko te ngaohiko tuku pūhiko he 0.8 ~ 1.65V. He āhuatanga whakamahi noa tēnei mō ngā pūrere rama iti-mana pēnei i ngā whakaaturanga LED. Ko tēnei tikanga e tika ana mō ngā hua hiko kawe hei whakahaerenga i ngā LED ma iti-mana me te kaha-waenganui, pēnei i ngā rama rama rama rama, ngā rama pōuri LED, ngā rama tēpu whakaora pūngao, etc. I te whakaaro ka taea te mahi me tētahi pūhiko AA, ā, he iti rawa te rahi, ko te
2. Ko te whakawātea Te mahere whakahaere ngaohiko teitei
Ko ngā rongoā mana iti-ngaohiko me te ngaohiko teitei ake i te 5 e whakamahi ana i tētahi mana whakahaere motuhake, i tētahi pūhiko rānei. Ko te uara ngaohiko e whakahohe ana i te LED he teitei ake i te heke ngaohiko o te ngongo LED, ara, he nui ake i te 5V, penei i te 6V, 9V, 12V, 24V, teitei ake ranei. I tēnei take, ka whakahaeretia te nuinga e tētahi pūngao mana whakahaere, pūhiko rānei hei whakahaeretanga i te rama LED. Me whakaoti e tēnei otinga mana te raruraru o te whakaheke i te ngaohiko mana. Ko ngā tono noa iho ko ngā rama māra solar, ngā rama kari solar, me ngā pūnaha rama waka.
3.Tūtukitanga Drive e whakawhiwhia ana ki te mana ā-tika mai i te mana matua, i te hiko tonu o te ngaohiko teitei rānei
Ko tēnei otinga e whakahaeretia ana mā te mana matua (100V, 220V rānei) te hiko ōrite-ngaohiko teitei rānei, ā, e whakamahia ana hei whakahaeretanga i ngā rama LED ma-nui-ngaohiko. Ko te pūkaha mana matua te tikanga tuku mana tino whai hua mo nga whakaaturanga hiko LED, a koinei te aronga whanaketanga mo te whakarahi me te tono o te rama LED.
I te wā e whakamahi ana i te mana matua hei whakahaerenga i ngā LED, me whakaoti ngā raruraru o te whakaheke i te ngaohiko me te whakatika. Me whai kaha anō te whakawhiti, he iti ake te rahi, he iti ake hoki te utu. Hei taapiri, me whakatutuki nga take o te whakawātea haumaru. I te whakaaro ki te pānga ki te whatunga hiko, me whakaoti hoki ngā take pāhekoheko hiko me te āhuatanga mana. Mō ngā LED kaha iti me te iti, ko te hanganga ara iahiko pai rawa atu he kaitahuri rere-hoki-tahi-motu. Mō ngā tono kaha nui, me whakamahi he arawhata hurihanga piriti.
Mō ngā kaihautū LED, ko te wero matua kei roto i te kore-rārangi o te whakaaturanga LED. Ko te nuinga o te wā ka puta tēnei i te meka ka huri te ngaohiko o mua o te LED ki te nāianei me te pāmahana. Ka rerekē te ngaohiko o mua o ngā pūrere LED rerekē. Ka rere te "wā tae" LED ki te nāianei me te pāmahana, me te kia te LED i roto i nga whakaritenga whakaritenga. mahi i roto i te whānuitanga mō te mahi pono. Ko te mahi matua o te kaiwhakahaere LED ko te whakaiti i te nāianei i raro i ngā āhuatanga mahi, ahakoa ngā huringa o ngā āhuatanga tāuru me te ngaohiko anga whakamua.
Mō ngā ara hiko whakaatu hiko LED, i tua atu i te hiko pūmau me te hiko pūmau, he ētahi atu whakaritenga matua. Hei tauira, mēnā e hiahiatia ana te whakaiti LED, me whakarato te hangarau PWM, a ko te auau PWM noa mo te whakaiti LED ko te 1 ~ 3kHz. Hei taapiri, me whai kaha te arahi a te taraiwa taraiwa LED ki te whakahaere i te kaha, kia kaha ki te tu atu i nga ahuatanga he maha, me te ngawari ki te whakatinana. He mea tika kia whakahuahia, nā te mea kei te āhua o te hiko pai tonu te whakaaturanga hiko LED, kāore e rere.
I te wā e pā ana ki te kōwhiringa o ngā rongoā taraiwa whakaaturanga hiko LED, i roto i te mua, i whakaaro te whakanui DC / DC ki te inductance. I ngā tau tata nei, kua piki ake te nāianei e taea ana e te kaiwhakahaere papu utu te whakaputa mai i ētahi rau miriona amps ki te 1.2A. Nō reira, ko ēnei putanga e rua o ia momo whakaoho he ōrite.
