Indlela yokusombulula ingxaki yokutshatyalaliswa kobushushu bomboniso wangaphakathi wenkcazo ephezulu?
Eyona ngxaki inkulu ebonisa inkcazo ephezulu yangaphakathi edibana nayo ngoku kukutshabalalisa ubushushu.Iziboniso zenkcazo ephezulu yangaphakathi zisebenzisa amandla amaninzi, kwaye inxalenye enkulu yamandla ichithwa ekufudumeni.Umkhuhlane unokubangela iingxaki ezininzi.Ngoko ke uyisombulula njani ingxaki yokutshatyalaliswa kobushushu bomboniso wangaphakathi wenkcazo ephezulu?Umenzi womboniso wangaphakathi wenkcazo ephezulu-Isikrini esitsha se-Optoelectronics sishwankathela la manqaku alandelayo:

1. Ukwandiswa: Okukhona umboniso omkhulu wangaphakathi wenkcazo ephezulu, kokukhona utyalo-mali oluphezulu kwisixhobo somgca wemveliso.Ukunyuka kobukhulu bomboniso wenkcazo ephezulu yangaphakathi kulula kakhulu, njengeebhloko zokwakha.Isisombululo kwakhona kulula ukufikelela ngokweemfuno zabasebenzisi.

2. Umbala opheleleyo: ii-bulbs ezikhanyayo, izibane ze-neon, njl. Zonke ziyi-monochrome, kwaye i-LED iqaphela ukudibanisa kwe-RGB imibala emithathu ephambili.

3. Ukuthembeka okuphezulu: I-LED yokukhanya okuqinileyo kunye nokuthembeka okuphezulu, ngokungafani ne-neon tubes, ii-bulbs ezikhanyayo kunye nezinto ezinjalo ezifuna iibhubhu ze-vacuum.

4. Ubomi obude: Ubomi bethiyori be-chips ze-LED bunokufikelela kwiiyure ze-100,000, kwaye ubomi bokwenene bungaphezulu kweeyure ezingama-30,000.

5. Ubume bendalo: Umboniso we-LED ngokwawo yimveliso egcina amandla kwaye ingenangcoliseko.

Ke buvela phi ubushushu bomboniso wangaphakathi wodidi oluphezulu?Ukusuka kumandla ombane ukuya kwizibane ze-LED, ukuya kubaqhubi be-LED, ukuya kwii-resistors ezihlengahlengiswayo, indawo yokufudumala ibandakanya izibane ze-LED, abaqhubi be-LED, kunye neentambo ze-LED.Masithathe unikezelo lwamandla lwe-5V njengomzekelo:

1. Ukusebenza okukhanyayo kwe-LED kumalunga ne-20%, kwaye ubushushu be-LED bubalelwa kwi-50% yobushushu bubonke.

2. Umlawuli kunye neengcingo ezidibanisayo malunga ne-5% yexabiso le-calorific lilonke

3. Ukuhla kwamandla okuqhuba: I-1.8V (G / B) okanye i-3V (R) i-voltage drop, ukufudumeza inxalenye yokuqhubela phambili kubala ngaphezu kwe-45% yokufudumala okupheleleyo.

Isizukulwana sobushushu se-indoor high-definition display izibane ze-LED kufuneka ziphucule ukusebenza kakuhle kwe-LED.Kukho indawo eninzi yokuphucula kwisizukulwana sobushushu secandelo lokuqhuba, elikwayinxalenye esilindele ukuyiphucula.
