how do i stop spotting on led lighting?
Hi all.
We recently completed an installation of architectural letters. Fitted externally and lit them using LED lighting on the rear of the letters.
The letters have ‘returns’ on them and the lighting was installed ‘within’ the letter.
Unfortunately now they are lit we are experiencing ‘spotting’ rather than a consistent ‘halo’ effect around the letters.We are thinking of putting something on the back/within the back of the letters to diffuse the light, but not exactly sure how to go about this.
Anyone got any ideas / suggestions ?
Thanks in advance for any help. 😉

The best way to diffuse the light will be to add a 3mm thickness opal acrylic backtray into each letter. If you talk to Vince at Phoenix Signs (he’s usually lurking somewhere on the forum) 01843 228682 – he should be able to help you out.
Good luck

how have you loacted these to the sign face?
inconsistant halo’s can be caused by several reasons. the most comon is positioning and things like the location of lactors and the like.
what do you have on the rear, if anything? -
Thanks Guy,
Ady, I know Robert will be able to help you more on this, as he knows far more than i do about Led’s. Any construction probs i can help you with.
Regards

Hi .
These have been fixed to acrylic panels via brass locator fixings.
had thought of getting another set of the same text cut in acrylic and fitting them in the back, was just a bit concerned whether they would ‘match-up’ with the text that is already there ? -
The big problem i can see, how will you fit the perspex back?
Normally the letters would be punched to accept 1/2 brackets which the perspex is pop rivited to. This prob has not been done.
Backs can be done one of two ways, either a tracing of the back of the letter, or cut the backs slightly smaller than the face of the original artwork.
Fixing these with locators in the back will be the problem. I guess these have been soldered into place, which will have to be removed for the perspex to sit flush with the back.
If the spotting is a major problem, i can see the only way is for the letters to be taken down, and ask who ever made them to remove the bridges, and fit backs. Ask them to do this as quick as poss for you.
Not unless any one can see an easier way.
