Angle mount LED

Ok, here's my question:



What is the easiest way to mount LEDs at a slight angle
Also...mounting stuff must be outdoor friendly...so wood is not a great idea.

The blue lines are the path of the LEDs
and the green cloud is the approx. illumination i'm going for.

This is what i have to work with for space...not much.

This is what i don't want to happen:
(no light hits the plate.[/img]

i think if you can get in there with a drill and drill out the holes, you can drill them at the angle you want and the LED will slide it and paint at the angle that you drilled. i use a 13/64" bit and they fit pretty good

Flatten the heads of the LEDs

is that to achieve a less focused beam? explain, please

problem with that is what i illustrated in this picture:


The LED doesn't sit flat with anything. That's why i was wondering if anyone knew something to use as a wedge to mount the LEDs on. Or should i just do it that way and super glue it. lol?

ok, but if i use wood it will rot (remember...this is a roll pan) and also, how do you recommend i make that angle cut? (chop saw?)

well you could do a few things.

* you could use wood and seal it (polyurathane, a few coats of that would work for a long time, also do it after you drinn your holes)

* technically you could use metal but that would definately be harder to drill on an angle.

*a good chunk of plastic would work nicely.

* Is it possible to layer figerglass then drill that out on an angle. You do some fiber glass stuff so you could get pretty creative.

In wood I would just make the angle cut with a drill bit or with a dremel(not sue what bit but I am sure they is one that would work)

Yeah. I have 19 flat LEDs as turnsignals in the front and they "fill" the turnsignal housing more than the regular LEDs I had in there before. Those looked like a "spot" in the housing.

flat tip dispurses light better....

and use hot melt glue...

Did you flatten em yourself? or Buy em that way?

I bought mine that way...

oh...i flattened it a lil and there was very little difference...and then i took it down some more...and there is NO spotlight effect...think it might work. Although the overall output seems to have decreased.

Like he said. The hot glue is weather proof and can help hold the LED at the angle you need. That's how all 8 of my LED's are held in place.

the light output is the same.. it's just divided up by a wider area.

Yea, i was gunna use super glue...similar properties.

Where are your LEDs?

After i flattened the LEDs with a sander it doesn't look like the angle is going to make a big difference.

I would try shoe goo. I would think it would hold better to the roll pan.

if i knew what you were referring to i might try it.

i see no problem with that, noone will see the backside of it anyway, if anything just take off the edge thats holding up and leave the other side so it fits into the hole better. or drill that size hole, and use a slightly larger bit and drill it at the same angle just not all the way through. the LED should fit flush into the larger hole

corvettecrazy wrote:

I'd take this design, however just use existing material (don't add wood to it) and do 2 holes. The first hole will be the size of the diameter of the smaller point of the LED, the second hole would only go halfway down and be a little larger to accomdate the larger part of the led. Make it so the tips of the LEDs stick out just a little. I'd use some silicon to seal the back side of it. Once you have that all in place, I'd take a sander and flatten the tips of the LED to make it flush with the rest of the bumper. It'd make for a clean install that looks like there is nothing really there by day, and you won't be able to feel, or push them in either, as they'd feel like they are part of the body, but by night, the flattened tip would spread the light a little better, and they would give you the lighting effect you want.

I'd also possibly consider increasing the angle of the LEDs so that the focus of the center of the LEDs is 3/4ths up the plate, and then adding a row of LEDs on the bottom facing the bottom 1/4th of the plate. The crossing between the outer edge of the top set of LEDs and the bottom set of LEDs would give a wider range of illumination and make it look more evenly lit, rather than only being able to see a small section of the plate.

I went with 4 across the top and 2 on each side.



Here they are at night.



Mine are only at a slight angle but they get the job done.

the 4 on the top are exactly what i'll be doing. How are you LEDs wired though? It seems like i can only get 4 white LEDs to light on 12V if i do 5 LEDS they don't light.

Mine are all wired in parallel. Each one has it's own resistor. It was just easier that way since I didn't know how many I wanted to use.

Hey mike, the glow in your grille, what did you use, I am thinking about putting something in there, but not sure what would be the best

thank you bobby lee
