Post by beby.ngepot Thu 29 May 2014, 23:26

malem semua.

sebelumnya... saya minta maaf baru bisa ngepost. karna ada kesibukan dan halangan yg bikin postingan jadi ketunda lama.
omm momod. saya ijin mulai posting yakk... Very Happy 



langkah pertama : menghayal Rolling Eyes 
kira" led seperti apa yg mau dibuat, komposisi warnanya, komponen apa aja yg mau dipakai dll.
setelah saya menghayal. saya pengen bikin led dengan ukuran body 50cm x 40cm, pakai switching power supply, casing + fan, switch buat channel, dan yg ekonomis tentunya hahahaaa...


[You must be registered and logged in to see this image.]
ini yang mau saya buat.

kenapa banyak birunya??
karna saya suka cahaya yg bluiss...  Laughing



bahan" yg dibutuhkan :

1. high power led @3w royal blue 445nm : 51ekor
2. high power led @3w white 10.000k : 12ekor
3. lensa+tatakan saya pakai 90degree : 63ekor
4. heatsink : aluminium plat 3mm ukuran 52cmx40cm
5. switching psu : saya pakai 2ekor untuk masing" warna
6. aluminium profil channel (bentuk U ) lebar 5cm yg diperlukan sekitar 184cm
7. aluminium profil corner (bentuk sudut)lebar 2.5cm untuk setiap sisi. yg diperlukan sekitar 60cm.
8. acrylik untuk cover belakangnya. ukuran 52x40. saya pakai ukuran 3mm.
9. fan dc 12v ukuran 12cm : 2ekor
10. kabel tunggal/kawat/engkel ukuran 0.75
11. thermal glue


alat :
1. tespen
2. avometer
3. tang kupas kabel
4. gergaji besi
5. bor (mata mm untuk lubang heatsink dan 3.5mm untuk lubang rivet)
6. rivet / paku tembak / paku keling pakai ukuran 3.5mm
7. solder+tinol (solder saya yg 130watt, pernah pakai yg watt kecil dan kecewa berat)
8. cappucinno panas Twisted Evil

mulai bikin Very Happy 

baca doa dulu....


wokehhh...
1. siapkan heatsink platenya
[You must be registered and logged in to see this image.]

2. permukaan heatsink yg mau ditempelin led ditutup pakai lakban kertas.
dari gambar tadi sudah diatur penempatan dan jarak antara led.
[You must be registered and logged in to see this image.]

3. setiap persimpangan garis diberi jarak 2cm dan di bor (2mm). usahakan arah lubang bor sejajar. mengarah ke susunan led selanjutnya.
[You must be registered and logged in to see this image.]

setelah di bor buka lakban. hasilnya...

casing :
1.  potong aluminium profil channel:
52cm x 2
37.6cm x 2

2.  potong aluminium corner :
5cm x 4

hasil casing setengah jadi:

malem semuanyaahh....  Laughing 

sebelum solder menyolder. ada sedikit yg mau saya bagi"...
saya kasih bagi dosa saya hahahahaaaa  Laughing 
becanda...

sebelum mulai nyolder. pastikan sudah punya / sudah bikin diagram dari led mau dirangkai.
beberapa hal yg harus diperhatikan:
1. output psu yg dipakai. (volt dan amperenya)
2. penempatan lednya.
3. alat tambahan apa aja yg mau dipasang di rangkaian tsb (switch, fan, fuse dll terserah. saya yg simpel aja  Smile  )
4. spek dari led yg dipakai. soalnya gak semua led itu speknya sama.




KALAU pakai psu 12v.
led @1w bisa di seri 3ekor led + resistor 3.6 ohm
led @3w bisa di seri 3ekor led + resistor 1.8 ohm

kalau saya pribadi selama ini pakai switching psu. saya gak pernah pakai resistor.
saya pakai switching power supply. output dari switching psu saya adjust di 10.8v.
kenapa gak perlu resistor?
soalnya tegangan (v) psu kalau dibagi jumlah led dalam 1 seri, jumlahnya masih masuk dalam range tegangan kerja led.

psu apapun bisa dipakai. selama outputnya DC dan serangkai sesuai aturan.
charger laptop? bisa
psu komputer? bisa
psu radio amatir? bisa

tegangan adaptor yg UMUM itu 12v, 18v, 19v, 20v, 24v
12v = seri 3led + resistor
13.8v = seri 4led tanpa resistor
18v = seri 5led tanpa resistor
19v = seri 6led tanpa resistor (agak kurang. mending cari uh 20v. kadang harganya sama aja)
20v = seri 6led tanpa resistor
24v = seri 7led tanda resistor

berapa led yg bisa dirangkai kalau pakai 1 adaptor/psu?
tergantung seberapa besar kapasitas ampere dari psu/adaptor itu.
saran saya. pakai maksimal 80% dari total kapasitas.
psu ini ibarat jantungnya rangkaian led. jadi usahakan jangan pelit sama harga...  Very Happy  hahahaaaa



masuk kerangkaian.
[You must be registered and logged in to see this image.]

ini gambar sederhana tentang led susunan seri dan paralel.

resistornya mana?
resistor bisa ditaro sebelum led atau sesudah led.

switchnya harus di belakang?
gak harus. tapi lebih baik dibelakang. sebisa mungkin kita mengurangi hambatan. switch di taruh di depan (di kabel +) berarti pasti ada sambungan. sambungan ini bisa bikin hambatan, ini yg dihindari. jadi mending ditaruh di belakang.

om rony saya tambahin dikit deh alat yg harus disiapkannya
Teh Tarik + Dunhill mild...gentleman its a taste......
hahahha....mantap om ulasannya, bermanfaat banyak buat yg baru mau mulai custom kaya saya...terutama saat mau aplikasi pake PSU.....saya kaan lbh suka yg instan, pake led driver saja.
Salam kenal om rony..

Hi, you are using the flat alumi heatsink for 3W led, did you test the temperature after the led is on ? I feel that the heatsink is not good enough and the temperature is high and cause the short life of led.

Hi Thaoti...regard from Bandung-Indonesia.
I think only use 2pcs cooling fan would be work well on it brotha....at least works for mine custom led...about 2 years n still on.

hello thaoti...
usually. i use 2pcs fan 8cm on that case dimension..
this time i try to use 2pcs 12cm fan. but a bit loud (its cheapest fan on the store)
maybe next time i'll try using single 15cm fan Laughing
heheee
i never test the temperature. i think 3mm without fan is enough for 60watt (24pcs epistar/brightlux). but i need fan if i use more than 24pcs led.

putra : beli lembaran di toko besi (bukan toko bangunan ya). kalau mau beli yg ketengan (eceran hhahaa) di tukang bubut biasanya ada. harganya kalo disini 80rupiah/cm persegi.

omm deka : gaya... yg ngajari saya main led kan omm deka. hehee

pak boyan : cappucinno lebih gregeettt di lidah pak hehee.. coba pakai psu atau adaptor pak. rasakan perbedaan hematnya hehee... jaauuuhhh...

Post by agusto198 Wed 11 Jun 2014, 22:18

mau nanya..dengan penggunaan switching psu di set 10,8 apakah ga pengaruh ke panas yang ditimbulkan..voltase diturunkan tapi ampere yang diperlukan tiap chipled kan sama..misalkan dipakai 3pc chipled 3w..dengan asumsi tiap chipled 700mA..panas yang dikeluarkan adalah sama..karena ampere yang menentukan panas bukan nya voltase.. menurut saya penggunaan resistorlah yang membantu pengaturan panas jadi chipled akan lebih awet..apabila tanpa resistor maka panas akan langsung terbebani di chipled..dan led akan cepet habis masa nya...ini saran saya ya.. Laughing Evil or Very Mad
