mangsa eksiden... dah terbaring atas "kerb" lebih kurang setahun... baru2 nih terpikir nak buat projek pakai LED, maka terpikir aku boleh "Salvage" LED tuh...



bawak balik umah, kasi cuci dan blow ngan hair dryer, pastu pasang ngan elektrik rumah 250v, 50Hz.

keputusan : semua menyala! hijau, merah dan kuning. LED sihat walafiat, dan juga jenis high quality...

next step, aku nak pakai soldering iron, cabut satu-satu. buat experimen... kalo ader lebih aku buat sedekah...

kalo sesaper ader nampak mana2 traffic light LED yg jadi mangsa eksiden tuh, inform sket, aku pegi salvage...

berminat lak ngan lampu blakang LED nih..

trunks duk pkai lagi ka skrg?

nak tgk gambar!

trunksz pakai bkn fully LED klu x silap aku laa.. dia tambah sebiji mentol.. btul x trunksz??

alasan yang trunksz bg sbb x terang.. klu tgk pada garis lurus br terang..

L.E.D. CONVERSIONS
For Ducati Monster Tail Lights

As many of you have probably noticed by driving around, many tractor trailors, mass transit vehicles, and luxury cars are now using LED's for turn signals, brake lights, and tail lights. I've been intrigued by the way the light from these lights seems clear and focused and is visible from a longer distance. Looking further into the topic, there are even more advantages to LED's. If they are not overdriven (supplied with too much current for a gain in brightness) they can last thousands and thousands of hours of operation. LED's are solid state devices that convert electrical energy to light typically at 90% efficiency or better, compared to a light bulb that is typically 40-60% efficient. They give off very little heat, and the LED package is not nearly as sensative to vibration as a light bulb is. The goal here is to make the tail light more reliable, visible, and hopefully safer...

I made a basic prototype of the array with 24 LED's. At full brightness, the brake light was very visible, but the running light needed a little help. This version uses 45 5mm LED's. Step 1 was to measure the inside of the lense and develop an attractive placement pattern for the LED's. I decided to follow the contours of the tail lense, because the prototype was a rectangular pattern, which I didnt like the look of.




Here is my drill pattern in both AutoCAD and Adobe PDF:

LED's were glued to the Lexan holder and soldered up into a series-parallel combination.





Resistor values of 150ohms and 16ohms were selected for the running and brake inputs.



Looks interesting behind the stock lense. Originally I was considering a clear tail lense, but I like the stock look.





Ready for the lense cover....


mende yg sama tailight untuk duc monster tp link lain... litar pon lain sikit jer... resistor jer bertambah... tak tau ler yg mana plg ok...






link utk yg nie.... http://www.keld.eu/led/index.htm

sweetlah....nie buleh jadik next project

up sket topic nih.. lpas pikir2 nk wat tail light nih aku ade 2 option.. 1 dh tny bro rimau.. 1 lg nih nk pkai led.. aku pkai led 5mm tuh kot (saiz kecik yg std tuh..bkan besa jari tuh)..led jernih..lampu merah..super bright.. max volt led tuh bley trime bape ye?? td aku try2..check kt tiap led tuh ade la 1.9 volt xbape terang.. lg 1 aku try bley tahan la terang 2.5 volt.. kalo up lg tahan ke led tuh??
