Hi,
I'm just about to complete my second strip board of uv leds for a two sided uv light box, based on an online instructable. The specifications for the recommended led (168 in total) have been provided, although the instructable, other than in a general way, is very light on in regard to detail for the housing of the led boards. Other online help similarly lacks detail for my needs. I'm not talking of general dimensions of the overall construction but rather internal aspects that are important to the design. Basically, I want to make a simple, light weight housing of modest dimensions to accommodate the boards.
In particular, I would like to know a couple of things, although there may be more issues that you also consider important and relevant.
Firstly, is there an optimum design distance between the circuit artwork & the the upper & lower led boards for the construction? (I'm thinking that for commercial boxes there is probably an engineering formula for that distance, but I don't want to get too anal about it). Also, some commercial units use a vacuum seal for the artwork. I don't know if it is possible to simulate that in a simple way, without going overboard.
Secondly, is perspex a satisfactory option, as opposed to glass, to sandwich the artwork.
Any help that you can provide would be helpful.
Thanks.
