specific Embodiment 1
[0054] Household handheld optical fiber coupled ultraviolet LED sterilizer and sterilizing method
[0055] 1. Take 50 UV LED chips with a size of 1mm×1mm, the wavelength is 275nm, the voltage of a single chip is 6V, and the power at 350mA is 50mW. After each chip is packaged, a lens is installed, and a light collimator is installed at the same time.
[0056] 2. After the collimator, connect the optical fiber, a total of 50 optical fibers, the ultraviolet LED light coupled by these 50 optical fibers is a collimated parallel point light source, and the diameter of the point light source is about 0.5cm.
[0057] 3. Parallel the ultraviolet LED light coupled from these 50 optical fibers into a straight line to form an ultraviolet light source. The length of the line light source is 25cm.
[0058] 4. The ultraviolet light source made in the above 1-3 steps is integrated in a hand-held box, and a rechargeable power supply is also integrated in the hand-held box. The handheld box c...
