Abstract
A miniature strobe-type flashing safety light source, to be worn by a person or pet after dark. A plurality of high-intensity LED's producing a total of at least 6 candelas when energized are surrounded by a striated refracting lens, the axes of the intense light cones being oriented between 20 and 40 degrees above the horizontal plane and impinging on the striations. The LED's are periodically and simultaneously energized.
Claims4
A low-power light-weight flashing light source, said source comprising:
- a. a plurality of high-intensity separate LED's, said LED's producing when energized a total of at least 6 candelas, each said separate LED producing when energized an intense central cone of light directed along an axis individual to said separate LED, said axes being oriented between 20 and 40 degrees above the horizontal plane;
- b. a refracting lens having a perimeter, said lens surrounding and covering said plurality of LED's, said lens comprising a plurality of refracting striations about said perimeter, said LED's and said striations being positioned and oriented such that said striations intercept and scatter said intense central cones of light whereby said light source may be readily seen by observers 360 degrees around said light source;
- and
- c. electronic power supply means for periodically and simultaneously energizing said plurality of LED's.
