Hermetically-sealed light fixture for hazardous environments
First Claim
Patent Images
1. A light fixture disposed in a hazardous environment, comprising:
- a base comprising at least one wall that forms a cavity, wherein the at least one wall comprises at least one lens mating surface;
a lens comprising at least one base mating surface that forms a hermetic seal with the at least one lens mating surface, wherein the hermetic seal comprises a fusion between the at least one base mating surface and the at least one lens mating surface, wherein the hermetic seal encloses the cavity; and
at least one solid state light source disposed within the cavity.

Abstract
A light fixture is disclosed herein. The light fixture can include a base having at least one wall that forms a cavity, where the at least one wall includes at least one lens mating surface. The light fixture can also include a lens having at least one base mating surface that forms a hermetic seal with the at least one lens mating surface, where the hermetic seal encapsulates the cavity. The light fixture can further include at least one solid state light source disposed within the cavity.

17. A lighting system, comprising:
-
a power supply; and a light fixture electrically coupled to the power supply, wherein the light fixture comprises; a base comprising at least one wall that forms a cavity, wherein the at least one wall comprises at least one lens mating surface; a lens comprising at least one base mating surface that forms a hermetic seal with the at least one lens mating surface, wherein the hermetic seal comprises a permanent adhesion between the at least one base mating surface and the at least one lens mating surface, wherein the hermetic seal encloses the cavity; at least one solid state light source disposed within the cavity, where the light fixture is disposed in a hazardous environment. - View Dependent Claims (18)

19. An enclosure, comprising:
-
a first enclosure portion comprising at least one first wall made of a first material, wherein the at least one first wall comprises at least one first mating surface, and wherein the first material of the at least one first wall has a first coefficient of thermal expansion; a second enclosure portion comprising at least one second wall made of a second material, wherein the at least one second wall comprises at least one deflection member and at least one second mating surface, wherein the first enclosure portion and the second enclosure portion, when coupled to each other, form a cavity, and wherein the second material of the second enclosure portion has a second coefficient of thermal expansion that is greater than the first coefficient of thermal expansion of the first material of the first enclosure portion; and at least one heat-generating device disposed within the cavity, wherein the at least one first mating surface and the at least one second mating surface abut against each other to form a seal, and wherein the at least one deflection member changes form to maintain the seal when the second enclosure portion, when exposed to heat, expands at a higher rate than the first enclosure portion. - View Dependent Claims (20)
