I did some tests for a purely aesthetic feature of my device. The light from the upward facing LEDs will ‘bleed’ into a surrounding perspex ring. This produces an interesting visual feature for any audience that may be watching a performance. The thinner perspex (1mm) produced more seamless transitions between the LEDs with less defined illumination. The frosting also distributed the light a bit better. It is also worth mentioning that the LEDs in the videos are pointing directly at the Perspex strip. In reality the light will come from the side of the bulbs…more testing!
