Outer back fixture testing with UVc energy flux test strips.
See testing video above.

Figure 18 (right)

UVc energy flux test strip placement on the front face of the cart, to see if the designed fixtures output enough energy for the surface to be sanitized to a log 3 reduction

Figure 17 (left)

Fixture Assembly, where the internal side panel is shown here. The lamp holders are mounted on the top and bottom edge, with the ballasts mounted on the back, serving as a power supply

Figure 6 (left)

CAD model of the fixture array configuration for the sides of the shopping cart. Bulbs will be horizontally placed into tombstones and attached to sheet metal.

Figure 5 (right)

Model of side fixture array configuration attached to side of the shopping cart. Bumpers will be added to create space between UV bulbs and cart.

Figure 4 (left)

Initial CAD model of the fixture. Purple bar depicts the UV light bulb that will be placed inside the lamp holder.

Figure 3 (right)

Bulbs will be placed 70 milimeters away from each other, measure from the radius of each bulb

Figure 2 (left)

CAD model of the frame concept around shopping cart. Single nut with button heads are one of the options for fastening. Cables with looped ends can grab the nuts and can be be adjusted if this method is to be used.

Figure 1 (right)

CAD model of the fixture placement around the shopping cart. UV light fixtures will be placed on sides, front, back, bottom, and around the basket and handles of the cart.
