Abstract

A first light-emitting unit (11a), a second light-emitting unit (11b), . . . are disposed near a tip vicinity of a spinner cover (1) of a propeller (2). The first light-emitting unit (11a) embraces a first bulk-shaped lens of bullet-like, and a semiconductor light-emitting element is installed in a cavity of the first bulk-shaped lens. The second light-emitting unit (11b) embraces a second bulk-shaped lens of bullet-like, and a semiconductor light-emitting element installed in a cavity of the second bulk-shaped lens. The first light-emitting unit (11a) and the second light-emitting unit (11b) are formed so as to be able to attach to and detach from the spinner cover (1) as an attachment (4) for bird strike protection.

Claims

1. The frightening apparatus comprising:

a bulk-shaped lens; and

a semiconductor light-emitting element installed in a well-shaped cavity formed at backside of the bulk-shaped lens,

wherein outer diameter of contour surface of the bulk-shaped lens is larger than three times and smaller than ten times of inner diameter of the cavity.

2. The frightening apparatus of claim 1, wherein a plurality of the semiconductor light-emitting elements are installed in the cavity.

3. The frightening apparatus of claim 2, wherein positions of top surfaces of the semiconductor light-emitting elements are displaced mutually so that these positions are not aligned on a single plane.

4. The frightening apparatus of claim 1, wherein two of the bulk-shaped lenses are disposed, imitating an eyeball of a face of an animal.

5. The frightening apparatus of claim 1, wherein the semiconductor light emitting element comprises three LED chips, emitting lights in red, green, blue respectively, stacked vertically or disposed closely, so that emitted light color can be changed by adjusting bias of each LED chip.

6. The frightening apparatus of claim 5, wherein, based on empirical rules and learning content of animals, the emitted light color is adjusted to a color that an intended animal hates extremely.

7. The frightening apparatus comprising:

a bulk-shaped lens disposed at a tip vicinity of a rotating body; and

a semiconductor light-emitting element installed in a well-shaped cavity formed at backside of the bulk-shaped lens.

8. The frightening apparatus of claim 7, wherein outer diameter of contour surface of the bulk-shaped lens is larger than three times and smaller than ten times of inner diameter of the cavity.

9. The frightening apparatus of claim 7, wherein the semiconductor light emitting element comprises three LED chips, emitting lights in red, green, blue respectively, stacked vertically or disposed closely, so that emitted light color can be changed by adjusting bias of each LED chip.

10. The frightening apparatus of claim 9, wherein, based on empirical rules and learning content of animals, the emitted light color is adjusted to a color that an intended animal hates extremely.

11. The frightening apparatus comprising:

a plurality of bulk-shaped lenses disposed around a predetermined central axis; and

semiconductor light-emitting elements installed in well-shaped cavities formed at backsides of the bulk-shaped lens,

wherein animation is displayed by turning on and off the semiconductor light-emitting elements sequentially.

12. The frightening apparatus of claim 11, wherein outer diameter of contour surface of each of the bulk-shaped lens is larger than three times and smaller than ten times inner diameter of the cavity.

13. The frightening apparatus of claim 11, wherein each of the semiconductor light emitting element comprises three LED chips, emitting lights in red, green, blue respectively, stacked vertically or disposed closely, so that emitted light color can be changed by adjusting bias of each LED chip.

14. The frightening apparatus of claim 13, wherein, based on empirical rules and learning content of animals, the emitted light color is adjusted to a color that an intended animal hates extremely.
