Sealing and Thermal Accommodation Arrangement in LED Package/Secondary Lens Structure
First Claim
1. In an LED apparatus including (a) a mounting board, (b) an LED package thereon with a primary lens, and (c) a secondary lens member over the primary lens and establishing a light path therebetween, the improvement comprising a resilient member against the secondary lens member in position other than in the light path, the resilient member yieldingly constraining the secondary lens member thereby to provide a weather-proof seal about the LED package while accommodating secondary lens member movement caused by primary lens thermal expansion during operation.

- 19. In an LED apparatus including (a) a mounting board, (b) a plurality of spaced-apart LED packages thereon, each LED package having a primary lens, and (c) a plurality of secondary lens members each positioned over a respective primary lens and establishing a light path therebetween, the improvement comprising a resilient member which includes a plurality of apertures therein, each aperture aligned with a corresponding light path, the resilient member yieldingly constraining the lens member and providing a weather-proof seal about each of the LED packages.
- 20. In an LED apparatus including (a) a mounting board, (b) an LED device thereon, and (c) a lens member over the LED device and establishing a light path therebetween, the improvement comprising a resilient member against the lens member in position other than in the light path, the resilient member yieldingly constraining the lens member thereby to provide a weather-proof seal about the LED device while accommodating movement caused by thermal expansion of the lens member.
