Weekly Progress
Ultraviolet LEDs can be manufactured to emit light in the ultraviolet range, although
practical LED arrays are very limited below 365 nm. LED efficiency at 365 nm is about 5-8%,
whereas efficiency at 395 nm is closer to 20%, and power outputs at these longer UV
wavelengths are also better. Such LED arrays are beginning to be used for UV curing
applications, and are already successful in digital print applications and inert UV curing
environments. Power densities approaching 3,000 mW/cm2 (30 kW/m2) are now possible, and
this, coupled with recent developments by photo initiator and resin formulators, makes the
expansion of LED-cured UV materials likely.

Engineering Analysis
Strong Point
- clean bacteria in the water, food
Week Point
- High energy some type when receive more might make skin of human burn.
Next Week Job
- At the moment , Id students thought many projects. I will try to tell them to choose only
one . After that, engineering students can do the job that is design circuit.
