Problem Description Summary

  • Issue Identified: Recent inspections of LED MPN: VSMY98545 have revealed damage and cuts at the left edge of the units.

  • Observation Details: The damage appears to be an overcut originating from the manufacturing process.

  • Technical Concerns:

    • High-Voltage Performance: There is significant concern regarding the impact of these cuts on dielectric strength in high-voltage applications.

    • Reliability Risks: The overcuts pose a potential risk for internal arcing or mechanical failure driven by thermal expansion.

  • Current Request: Formal technical assessment is required from the manufacturer to confirm if the units are still functional and reliable for use, or if this condition is considered normal.

Greetings,

The nature of the complaint is not entirely clear from the information provided, but it appears that the photo at right above shows a planar face on the lens of a device that should be approximately spherical. A lens deformity of this sort would produce a distortion of the emission pattern, making the product non-conforming to specification and eligible for return as such if received in that condition.
