What sort of LED will you run with the high mount brake light?

Will you be able to put the lid back after the LED are soldered onto the board? or you are not going to put the red lid on at all?

If you put the lid back on, you will need lots of high mcd LEDs as it blocks a lot of the light.

I got stuck at that point and will probly get back to it again this weekend. Keep us updated

[TypeG]

i wont put the lid back of coz as it never look LED if u put it on top
i going to put 20 LEDs on each row and there will have 7 rows altogether

[ahcash]

DLS .... can you make the picture smaller...

Otherwise.. well done..!!! can you do mind as well ?? HEHEHEH!!!

[cameltree]

I assume that you will run 20 LEDs in series and 7 rows in parallel. Will you have enough voltage to light up 20 of them to the full brightness? Again my assumption is running 5mm round LEDs.

I am actually thinking of using the superflux led. As I can neatly lay them side by side.

Not sure that the outcome will be but I will give it a try. If not I will probly try the 10mm ones. I like your thinkig as not to put the cover on. Might even spray the board to red colour.

Was it hard doing hte LED cabin light? Phillip has done some cabin lighting as well.

DLS .... can you make the picture smaller...

ADSL for the win!!!!

loads up for me in no time.

[TypeG]

superflux led? where u can get that?
I run 5-6 LED in series depends on the length of that row with certain amount of resistor which is way enough for brake. I have sprayed the board in red and will put a thin red tinted plastic on top of that as well. Till working on as it is quite time consuming.
For interior lights like dashboard, we need a BRIGHTER one not those gay 5mm one which I used for my brake and ceiling light.

it is not hard to do it. just go dicksmith and get everything u need. Also web is your frd. =)

[spoon fit]

i wont put the lid back of coz as it never look LED if u put it on top


u know y? becos ur LED not bright

[TypeG]

no
that's not an issue
coz the lid have its own pattern itself

[MRFIT]

impressive G...... take a pic of the back of board..... show us the connections of LEDs....

[spoon fit]

he won't share

[TypeG]

lol
who said that. I am angry now

[spoon fit]

lol
who said that. I am angry now

jk :wave:

[cameltree]

you can order superflux here (http://shops.bizarsoftware.com.au/ATAShop/catalogue/category16/category41/category86) . I like it because you get more viewing angle.

High brightness LEDs are only about 15 to 20 degree viewing angle.

Bought some 10mm 4-chip LED here (http://www.ledsales.com.au/leds.htm) which as 12,000 MCD and 180 degree viewing angle. It's exactly what i needed but there is a problem with that. The resister will be boiling hot after I leave it on for about 10 minutes( test run it on breadboard).

Will probly get those 1/2 Watt ceramic resister (huge ass) and run it and see the outcome.

To the extreme, you can try Luxeon LEDs and that will blind people for sure. It's good when you want to piss people who is tailgating you.

[ahcash]

lol
who said that. I am angry now

HE WON't SHARE.. http://board.hondasociety.com/images/paulie/smilies/hjtwofinger.gif

[TypeG]

to be honest, normal 5mm LEDs are more than enough for brake use since without the cover, it is bright and viewable anyway. I change them to LED since i got LEDs taillights and i want it to match with that so I will use normal 5mm one and will let u know how's the result.

[TypeG]

and the flex is bloody $2 each which is a bit costly for boot brake which is a BIG area if u want to make the pattern a bit neat and nice and it uses 50Ma

[CeeVicK]

nice... good job man!
is it very hard to do? might wanna do this on my frens jazz

[TypeG]

not that hard after u do some search on web. All u need is LEDs, resistor and the board plus some tools.
I will stop making the brake since I am going to buy some brighter 5mm LEDs from the Ledsale website and try it out.
Also I realized that the JDM LED taillight used superflux. =)

[cameltree]

The other way is to buy it from Honda. :D Not sure who has it in Aus?

[MRFIT]

i wonder how much Aus Honda is gonna ripp us off with it? :D

[spoon fit]

none on ozhonda

[TypeG]

what is the part number for that?

[asiansquad]

would it be
34272-SAA-901 ??

[petrovski]

Jus-10 has it . . . .

Pete :)

[Andys]

If anyone's interested, I converted my brake lights to LED using the following product:

http://www.ledshoponline.com/images/1157hyper.jpg

These have the advantage that they have LEDs shining out the side as well as forwards, so they light up the whole reflector. They are also the same width as the normal hole so fills it well. Finally, they run off 12V so no messing with resistors.

Basically I drilled out the lower unused brake section and put them in there, and left the upper section as my parking lights. I soldered it in myself and secured it with hot glue. If I was doing it again, I would buy the version with proper connector (not the bayonet fitting) which I know is available from the same manufacturer.

For the high mount brake light, I simply hot glue'd two of the same bulbs and its pretty bright. They take normal 12V so no messing with resistors or breadboards. At some stage I plan to add a third one as there is enough space and to make it look even brighter.

There even exists a similar product for indicators, however you need to add a large resistor OR change your blinking circuit, because otherwise it makes your indicators blink way too fast.


Cheers,

Jus-10 has it . . . .

Pete :)

he changed also?

[cameltree]

Andys,

I am also waiting for the similar product available from that website. According to them, those bulbs will be available in about a month time.


http://home.comcast.net/%7Evelocityusa/7443R1.jpg

Must be a big job to glue two of the bulbs onto the centre high mount brake. Do you run them in series or parallel?

[Andys]

Oh, cool :) It should be worth the wait, it'll make life alot easier. I'm thinking of doing the indicators too as I think it looks nice to have instant on/off when they're flashing. But for the brakes, I think LED is actually safer as it gives the driver behind another 50-100ms reaction time in an emergency.

Not really, have you ever used a hot glue gun? The glue sets clear so I went nuts and just literally glued them on facing forwards, then soldered it up in parallel. Series wouldn't make sense, it'd make it half as bright.

- Andrew

[cameltree]

I can picture how you get them on. I have just ordered some 3000 mcds red superflux led and that should be fun to play with.

Indicator is the next one I want to play with but really have to put up the load or it will just keep blinking like no tomorrow.

Tried Luxeon 1W led but it's pain in the butt.

[TypeG]

lol
i worked on my brake light again since i am not so worry about how bright it is but the look for the brake

[spoon fit]

pic pls

[cameltree]

Kind of working on the superflux LED 2000-3000 MCD each and can fit about 30 of them onto the PCB.

The pic will show you how bright the LEDs (3 of them) are with the flash turn on from the camera. Still trying to figure out how many I can fit onto the PCB without too much hassel. Viewing angle is about 90 degree with them.

Will post more pic once I got the full board working.

it look kind of .... bad if u going to put only few LED in that pattern on the board

[TypeG]

i used that b4
kind of useless to me

[cameltree]

haven't really figure out how to run them yet because space is a problem as superflux LEDs has 4 legs. +ve and -ve needs to run differently on them.

Will continue to think tonight and tomorrow and hopefully I can come out with something that looks better.

[TypeG]

wooo
that's sound so complex man
good luck and let us know
mine is nearly finish
have some sort of testing invove now
as I got many 5 LEDs network with 2 X 4LEDs and 3 LEDs network which need to figure a resistor which give out the same brightness with other 5LEDs network

[edw-R]

Good idea!!

Pic of all the LED on and the light is off. Can't see it directly or it will blind your eyes and that's why it's tilted to an angle before I take the photo.

Can't leave the cover off as I can light up my neighbour's backyard. I don't want any trouble from the authority. The pictures don't tell how bright the LEDs are. Pretty much will leave it as it is.

Please don't start flaming about how shit it looks as my aim of doing it is for safety reason as well as trying different LEDs from the market.

[TypeG]

can i see the back of the board
also i have no idea how 4 pins work
also my aim is to match the look of my LED taillight so the look is more important to me

[cameltree]

I will take some pic of the back of the board. Pretty much you have two pins for positive and two pins for negative. If you need to run them in series, you need to make sure +ve connected to -ve

Again it depends how you are going to run your power, the easiest way to run is by the following diagram. If not , i have solder multiple wires across the board to join them.

[asiansquad]

so when is someone gonna write a DIY manual for this????

[TypeG]

lol
it is hard to do a write up as they are simply just connect all LEDs together
here is my done up pictures which work up very bright usually normal Dicksmith LEDs and I got 90 pieces on the board which is enough to blind ppl.

how to make this part?

[TypeG]

use the tools

[asiansquad]

what kind of board do u need to purchase, from where and how much??

[TypeG]

errrrrr a bit of board which is big enough for your application
but i got the biggest one since u can crop them anyway
board cost depends on the size really

i got all my stuff in dicksmith

[Philip Lee]

hey TypeG, what's the brightless for those red leds u're using for the brake light?

thanks

[TypeG]

it is pretty hard for me to tell you how bright they are. It is not as bright as those superlex LED but with 90 LEDs light on at the same time, i can tell u they are bright enough for day time.

[Philip Lee]

i mean the brightness as in mcd.

thanks

[TypeG]

no idea mate as it hasnt mentioned in the package

[panda[cRx]]

any pics of it on the car man?

wanna do a step by step DIY for the article/reviews section?

[cameltree]

The brightness of the LED is different in comparison to viewing angle you get from the LED.

For example, a high brightness LED 10,000 MCD only has 15 degree viewing angle. It's not good if you use it for your main source of lighting. How often can you catch the light if you only have 15 degree to play with? You might have to work hard to fully utilise that 15 degree

Superflux LED only has 3000 MCD max. But it has 90 degree viewing angle. Chances of people seeing it are more than 10,000 MCD LED.

I have one LED that has 180 degree viewing angle and 12,000 MCD but it uses shit load of power to light it up and heat up very quickly. Not suitable for automotive lighting for the time being.

My suggestion is that, decide what how you are going to use it. Different type of LED has different uses.

Keep in mind that high brightness LEDs are EXPENSIVE.

[Philip Lee]

u're right cameltree, but centre brake lights don't need a very wide angle anyway.

the reason i ask is i wonder if 90 Leds with 15mcd be bright enough? cos those are very cheap.......

ps. Panda, DIY a Led circuit from parts isn't that easy and you'll need to understand the basic physics. there are tons of info on the internet and once u've kinda understand, it's just a matter of solder the leds and resistors on the circuit board.

[crankshaft]

Guys, how d u actually calculate the resistor needed? are there any web that explains how to wire these leds n resistors?
Thanks guys

[TypeG]

u are RIGHT as brake dun DO NOT need 90 angle at all. U can go Dicksmith and ask on their LED's mcd but I can tell you they are more than enough and cheap as u can see in the above pictures

[spoon fit]

not bad~

[DavidLing]

Guys, how d u actually calculate the resistor needed? are there any web that explains how to wire these leds n resistors?
Thanks guys

Basically, u can use this formular:
R = (E - V) / I

R = Resistecne
E = e.m.f (can say the voltage from the car)
V = Voltage (Voltage of the LED)
I = Current

e.g. if a LED is 2.3V 50mA (= 0.05A), and the emf is 12V
R = (12 - 2.3) / 0.05
R = 194 Ohm

But this formular only suitable for serial circuit in LED and Resistor:
------||------
|..................|
-{////}---@---

||: is the battery
{/////}: is the resistor
@: is the LED

So if u wanna put more then 1 LED, u can try to put this setting in parallel:

------||------
|..................|
-{////}---@---
|..................|
-{////}---@---
|..................|
-{////}---@---
|..................|
-{////}---@---
|..................|
-{////}---@---
|..................|
-{////}---@---

In this case, all the resistors are with the same resistance (ohm), and u no need to care about how many LEDs that u are using!

Actually, u also can use only 1 resistor with many LEDs! But u need to:
how the Voltage & Current in serial and parallel circuit;
understand the Ohm Rule; and
how many LEDs that u are using
In this case, the circuit will be more cmplicated!!

Ohm rules:
V=IR

You can have a look this website, however, it is in Chinese:

thx! :thumbsup:

[DavidLing]

thx! :thumbsup:

the website is about the basic phy. only! not telling u how to connect a LED!
But u can consider a LED as a resistor as well, then u will more understand how to calculate!

Actually, i found another website is telling how to light up a LED:

cool, i might get my mate to do it, he's done similar things to pc's and xbox's lol
