Light directing assembly for preventing light pollution
View Patent ↗A light-directing assembly is coupled to a light-emitting lamp. The assembly includes an opaque light shield having a top wall with a first opening. The light shield further includes a side wall coupled to the top wall and defines a second opening at a bottom edge. A light-directing assembly also includes a resilient washer having a central aperture and an outer dimension smaller than an inner dimension of the side wall. The central aperture of the washer is coupled to and receives a portion of the light-emitting lamp through an interference fit. The first opening of the light shield receives a second portion of the light-emitting lamp. A top wall of the light shield is supported by the washer and surrounds the light-emitting lamp. Thus, light from the light-emitting lamp is directed from the light-emitting lamp only out of the light shield and through the second opening.
1. A light-directing assembly adapted to be coupled to a light-emitting lamp, the combination comprising:
a substantially opaque light shield having a top wall with a first opening therein and a side wall coupled to the top wall and defining a second opening at a bottom thereof; and
a substantially heat-resistant, resilient washer having a central aperture and an outer dimension smaller than an inner dimension of said side wall,
said washer central aperture adapted to receive and be coupled to a portion of the light-emitting lamp in an interference fit therein,
said light shield first opening adapted to receive a second portion of the light-emitting lamp therein, and
said light shield top wall being supported by said washer and substantially surrounding the light-emitting lamp, thereby directing light from the light-emitting lamp substantially only out of said light shield through said second opening at the bottom thereof.
2. A light-directing assembly according to claim 1 , wherein
said light shield has a substantially frustoconical side wall.
3. A light-directing assembly according to claim 1 , wherein
said light shield top wall is substantially planar.
4. A light-directing assembly according to claim 1 , wherein
said first opening is smaller than the outer dimension of said washer, and said washer is not received in said first opening.
5. A light-directing assembly according to claim 1 , wherein
said washer is made from rubber.
6. A light-directing assembly according to claim 1 , wherein
said light shield has a substantially frustoconical side wall, said top wall is substantially planar, and said washer is made from rubber.
7. A light-directing assembly adapted to be coupled to a light-emitting lamp, the combination comprising:
a mounting electrical fixture having a lamp socket therein;
a substantially opaque light shield having a top wall with a first opening therein and a side wall coupled to the top wall and defining a second opening at a bottom thereof; and
a substantially heat-resistant, resilient washer having a central aperture and an outer dimension smaller than an inner dimension of said side wall,
said washer central aperture adapted to receive and be coupled to a portion of the light-emitting lamp in an interference fit therein,
said light shield first opening adapted to receive a second portion of the light-emitting lamp therein,
said lamp socket adapted to receive the lamp therein, and
said light shield top wall being supported by said washer and substantially surrounding the light-emitting lamp, thereby directing light from the light-emitting lamp substantially only out of said light shield through said second opening at the bottom thereof.
8. A light-directing assembly according to claim 7 , wherein
said light shield has a substantially frustoconical side wall.
9. A light-directing assembly according to claim 7 , wherein
said light shield top wall is substantially planar.
10. A light-directing assembly according to claim 7 , wherein
said top wall of said shield engages said mounting electrical fixture.
11. A light-directing assembly according to claim 7 , wherein
said first opening is smaller than the outer dimension of said washer, and said washer is not received in said first opening.
12. A light-directing assembly according to claim 7 , wherein
said washer is made from rubber.
13. A light-directing assembly according to claim 7 , wherein
said light shield has a substantially frustoconical side wall, said top wall is substantially planar, and said washer is made from rubber.
14. A light-directing assembly, comprising:
a mounting electrical fixture;
an electrical socket having a recess for receiving a light-emitting lamp and being connected to said fixture, the light-emitting lamp having a neck portion and a bulb portion, said neck portion adapted for insertion into said recess;
a substantially opaque light shield including a top wall with a lower engagement surface, a side wall, and a receiving end having a bottom edge, said top wall having a first opening, and said bottom edge defining a second opening;
a washer having a top surface, a bottom surface, and a central aperture for engaging the neck portion of the light-emitting lamp;
a lamp-receiving enclosure having a bottom wall defining an opening for transmitting light therethrough and a substantially horizontal plane; and
said top surface of said washer supports said lower engagement surface of said top wall for positioning said light shield relative to said neck portion of said light-emitting lamp for substantially preventing light from being emitted above said horizontal plane of said lamp-receiving enclosure.
15. A light assembly according to claim 14 , wherein
a diameter of the light-emitting lamp adjacent said neck portion is slightly smaller than a diameter of said lamp-receiving aperture, and said diameter of said lamp-receiving aperture is smaller than said top wall first opening, and
said washer is not received in said first opening.
16. A light assembly according to claim 14 , wherein
said washer is resilient.
17. A light assembly according to claim 14 , wherein
said washer is made from rubber.
18. A light assembly according to claim 14 , wherein
said washer is made from neoprene.
19. A light assembly according to claim 14 , wherein
said washer is adapted to withstand temperatures of about 180° Celsius.
20. A light assembly according to claim 14 , wherein
said light shield is made from aluminum.
21. A light assembly according to claim 14 , wherein
said light shield side wall has an inner surface having a reflective surface coating thereon.
22. A light assembly according to claim 14 , wherein
said shield side wall is continuous.
23. A light assembly according to claim 14 , wherein
said lamp-receiving enclosure is translucent.
24. A light assembly according to claim 14 , wherein
said recess has internal threads for threadedly engaging threads on said neck portion of said lamp.
