Harsh Environment Solidur® LEDs for Industrial Applications
Product Description
Cutting Through Darkness with Brilliantly Robust Lighting – Even in Harsh Conditions




In applications with high humidity, heat, pressure, or aggressive chemicals, the use of standard, non-hermetic LEDs is extremely limited and often only possible with an additional protective housing designed around the actual light source. The reason: LED chips and photo/laser-diodes are highly sensitive to moisture and other environmental aggressors such as high heat or chemicals, so they require special protection.
The solution: SCHOTT Solidur® LEDs and opto-electronic modules are made to work in applications that LEDs could not reliably withstand in the past due to harsh-environment conditions.
SCHOTT manufactures hermetically sealed and fully customizable Solidur® LED modules, offering superb illumination in an extraordinarily sturdy package. High-quality, vacuum-tight metal housings deliver complete protection for the internal LED chips – supporting long-term functionality for “fit-and-forget” application. Solidur® LEDs expand the limits of lighting integration, pushing into harsh environment and safety-critical settings previously unsupported by ordinary LED technology.

Technical Details
Technology:
Its hermetic assembly is the secret of the high quality and reliability of our LEDs:The gas-tight housings use SCHOTT’s specialty glass-to-metal sealing (GTMS) and ceramic-to-metal sealing (CerTMS®) technologies. SCHOTT’s GTMS component line is the product of decades spent developing and perfecting the process of permanently fusing glass and metal together as a means to create hermetic housings for the protection of sensitive electronics. SCHOTT is a world-leading glass manufacturer with 135 years of experience in the field.
SCHOTT functions as both a glass manufacturer and sealing house, offering the unique advantage of internal, vertically-integrated expertise and process control of every manufacturing step for its glass-to-metal sealed components.
