Unokukhetha njani unikezelo lwamandla kwiintambo zokukhanya ze-LED?

1. Iikhrayitheriya zokuthenga zobonelelo lombane lomcu wokukhanya

Iikhrayitheriya zokukhetha unikezelo lombane lomtya wokukhanya ikakhulu zibandakanya ubude bomgca wokukhanya, amandla kunye nokukhoyo komtya wokukhanya. Iikhrayitheriya zokukhetha ezikhethekileyo zezi zilandelayo:

1. Ubude bomgca wokukhanya: Ukukhetha umbane ofanelekileyo ngokobude bomgca wokukhanya kunokunyusa kakhulu ubomi benkonzo kunye nokuzinza.

2. Amandla oluhlu lokukhanya: Khetha unikezelo lwamandla oluhambelanayo ngokwamandla omgca wokukhanya. Okukhona amandla amakhulu, kokukhona unikezelo lwamandla olufunekayo.

3. Okwangoku: Khetha unikezelo lwamandla oluhambelanayo ngokuhambelana nomgca wokukhanya. Okukhona umsinga mkhulu, kokukhona unikezelo lwamandla olufunekayo.

2. Iinkcukacha zobonelelo lombane lomcu wokukhanya

1. Umbane we-12V: ulungele umbala omnye kunye nokukhanya okuphantsi kwe-RGB imicu yokukhanya, ngakumbi imicu yokukhanya emfutshane.

2. Unikezelo lwamandla lwe-24V: lufanelekile kwimigca yokukhanya ye-RGB ephezulu kunye nemicu yokukhanya emide.

3. Umbane we-48V: ulungele imicu yokukhanya emhlophe yamandla aphezulu, kwaye ilungele imicu yokukhanya edibanisa ukukhanya okumhlophe kunye nokukhanya kwe-RGB.

3. Indlela yokubala ngokuchanekileyo umthamo wombane wombane wokukhanya

Ifomula yokubala umthamo wamandla ombane wokukhanya yile: ubude bomgca wokukhanya (imitha) × amandla (W / M) ÷ ukusebenza kakuhle kwamandla (%) × i-coefficient (1.2). I-coefficient yi-1.2 ukuqinisekisa ukhuseleko nokuthembeka.

Umzekelo: Uthenge i-12V 5050 i-strip yokukhanya kunye nobude beemitha ezi-5, amandla e-14.4W / M, kunye nokusebenza kakuhle kombane we-90%. Ngokwefomula, sinokufumana:

5 (imitha) × 14.4 (W/M) ÷ 90% × 1.2 = 96W

Ke ngoko, kufuneka ukhethe unikezelo lwamandla lwe-12V kunye namandla angama-96W.

4. Indlela yokufakela unikezelo lombane lomcu wokukhanya

1. Umbane wombane wokukhanya kufuneka ufakwe ngendlela engangeni manzi kwaye uzame ukunqanda ukumanzi.

2. Ngaphambi kokufakela, kufuneka ukhangele ukuba i-voltage elinganisiweyo yonikezelo lwamandla kunye ne-voltage elinganisiweyo yomgca wokukhanya.

3. Coca imingxuma yokuchitha ubushushu bombane rhoqo ukuze uqinisekise isiphumo sokutshatyalaliswa kobushushu.

Ngamafutshane, kubalulekile ukukhetha unikezelo lombane lokukhanya olufanelekileyo, olungenako ukwandisa kuphela ubomi benkonzo yomgca wokukhanya, kodwa nokuqinisekisa ukuqaqamba kunye nesiphumo somtya wokukhanya. Ukuba awuqinisekanga ukuba ungakhetha njani unikezelo lwamandla olufanelekileyo, unokubonisana neengcali ezifanelekileyo.
