From the last consultation

  1. the shape and proportion of the whole lamp
  2. the opening gap was too small
  3. UV light (reflection) could not be seen, was not able to attract mosquito
  4. TiO2 shape to be changed, better if it can reflect the UV light

Changes made for this one

  1. the shape and proportion almost the same to the sketch chosen before.
  2. the opening gap is larger

Reasons for changes NOT made

3. UV light does not attract mosquito

"Mosquitoes are attracted to carbon dioxide and water vapor in the breath of mammals, not ultraviolet light.[6] "

In the case of bug zapper which often uses a fluorescent lamp designed to emit violet and ultraviolet light. These traps are not effective at killing biting insects (female mosquitoes and other insects),[5][6] being much more effective at attracting and killing other harmless and beneficial insects. A study over a summer found that 13,789 insects were killed, of which 31 were biting insects.[6]

the UVC should be used under enclosed environment for safety purpose

4. TiO2 shape

Because the UV light is best not seen, does it matter if the TiO2 shape is changed?

Opening is still too narrow -> reduce the overall size so the opening is bigger.

Blue light cant be seen

Proportion wise. (wider sphere, conical base)

Tio2 not a disc, make it a tube or smth. Better if it reflects the light outside to attract the mosquito. Can shape the mosquito
