5mm bricator chisonyezo chazilikitala ndi chikasu cha chikasu

Kodi mtundu wa mitundu iwiri ya utoto umakhala bwanji?

Bra-mtundu wa LED ikhoza kukhala phukusi ndi mabwinja a SMD kapena kudzera mdzenje la ndege. Mu 59fiirygc, ndi 5mm kudutsa mtundu wa LED ndi mandala omveka. Zomwe zimatha kutulutsa bwino kuchokera ku tchipisi cha LED. Ndiye zimagwira bwanji? Kungotsatira zotambalala ndikulumikiza polarity mololay yamakono, izi zimawunikira utoto momwe mungafunire. Monga dzina, mtundu wa BI-mtundu wotsogolera umatanthawuza kuti pali utoto awiri mkati mwa phukusi limodzi la LED. Timapereka chikasu chobiriwira ndi iR korona (880nm LED) mkati mwake

Kukula kwa 5mm bi-mtundu wa LED:

* Kukula kumeneku kumapezekanso mu IR korona, UV LED, LED yofiira, yofashoni ya LED, yobiriwira, Amber LED ndi LARD ndi LAMVA LA BRED ndi Blue. *

Magetsi owoneka bwino (TC = 25 ℃ )

Kupita Patsogolo kwa Kudutsa Kwawo:

Malo osungira

1. Pewani kudalira chilengedwe chinyezi ndikusunga malonda kuchoka pakusintha mwachangu;

2. Madongosolo Ayenera kusungidwa ndi kutentha ≤30 ℃ ndi chinyezi chaching'ono <60% ℃;

3. Zogulitsa mu phukusi loyambirira likulimbikitsidwa kuti lisonkhanidwe mkati mwa maola 72;

4. Zogulitsa mu phukusi lotseguka kwa sabata loposa sabata liyenera kuphika kwa maola 6-8 pa 85-10 ℃;

Njira Yoyenda Yokwera

1, stu d phula la LED liyenera kufanana ndi mabowo okwera pa PCB panthawi yophatikizika ;

Kupanga kotsogolera kungafunike kutsimikizira kuti phula lotsogola limagwirizana ndi dzenje ;

Onani chithunzi chomwe chili pansipa chofunikira kupanga njira zoyenera ;

Osatengera PCB Purce mu malo olumikizirana pakati pa Addframe ndi PCB kuti isalepheretse mabwalo ofupikitsa ;

2. Akayandira waya ku LED, waya aliyense wolumikizana uyenera kukhazikitsidwa mosiyana ndi chubu chotenthetsera kutentha kuti mupewe kulumikizana kwakanthawi.

Musakhale ndi mawaya onse mu kutentha kamodzi pamoto kuti asakane kutsogoleredwa ;

Kutakanani kupsinjika pamlingo wotsogolera kumatha kuwononga nyumba zomwe zimayambitsa ;

3. Use stand-offs(Fig 3)or spacers(Fig 4)to securely position the LED above the PCB ;

4. Sungani gawo locheperako la 3mm pakati pamunsi a mandala a LED ndi gawo loyamba la Bend (mkuyu. 5.)

5.During lead forming, use tools or jigs to hold the leads securely so that the bending force will not be transmitted to the LED lens and its internal structures ;

Do not perform lead forming once the component has been mounted onto the PCB ;

L ead Forming Procedures

1. Lead Forming Procedures ;

2 . Do not bend the leads more than twice (Fig. 7 );

3. During soldering, component covers and holders should leave clearance to avoid placing damaging stress on the LED during soldering(Fig 8) ;

4. The tip of the soldering iron should never touch the lens epoxy ;

5. Through-hole LED s are incompatible with reflow soldering ;

6. If the LED will undergo multiple soldering passes or face other processes where the part may be subjected to intense heat please check with Best LED for compatibility ;
