Abstract
A lamp comprises one or more light sources encapsulated as by casting in an inner relatively soft impact absorbing transparent material, such as polymerized silicone rubber, and in an outer relatively hard impact resistant transparent material, such as acrylic or glass. The lamp which may be used alone, or in combination with other protective housing components for specialized purposes, such as runway or highway lighting, is impact resistant, pressure resistant, completely sealed, waterproof, electrically insulated, and explosion proof.
Claims18
A fluid-tight self-cooling impact-resistant electric lamp comprising:
- a light source, and a multilayered casing having a translucent region and in which said light source is entirely embedded, said casing completely enveloping and in contact with said light source in sealed relationship for inhibiting transmission of shock forces to said light source, said multilayered casing comprising at least two layers of material, namely, an inner layer of material and an outer layer of material, with one layer of material being relatively more resilient thatn the other layer of material, and wherein said inner layer of material completely and seamlessly surrounds and is in contact with said light source and wherein said outer layer of material completely surrounds and is in contact with said inner layer of material, said inner layer of material adhering to said light source for maximum attenuation of induced oscillations resulting from said shock forces.
An electrically insulated impact-resistant fluid-tight sealed self-cooling explosion proof electric lamp comprising:
- an electric light source including a glass envelope;
- and
- a multilayered casing completely enveloping said light source, said multilayered casing at least comprising:
- an outermost housing translucent on at least one side and fabricated of a relatively rigid material, and a layer of relatively resilient transparent material within said housing in contact with said glass envelope and within which said light source is entirely and seamlessly embedded, said layer of relatively resilient transparent material adhering to said glass envelope for maximum attenuation of induced oscillations resulting from impacts imposed on said lamp.
