I am going to modify an HP vp6120 projector with 365nm UV LEDs, and was wondering if anyone knows what LED wattage would be sufficient for curing UV sensitive resin, or how to find it out by calculation.
Also I found these LED chips, however I am concerned that the light from the larger ones above 10w might be too diffused and omnidirectional (because of the number and the distance of/between the LEDs) as opposed to a projector lamp which emits collimated light. Has anyone experimented with the dimensions of the light panel surface which would still give you a focused image?
