CASE STUDY
Manufacturer of Plasma Grow Lights for Indoor Agriculture Requires EMI Air Vent Panels
Indoor grow light required EMI shielding to control and reduce radiated emissions and control electronics.
CUSTOMER CHALLENGE
A manufacturer of large scale commercial indoor agriculture developed a unique, low energy optimized light spectrum indoor grow light. The manufacturer needed a vent to cover the dual light bulbs, and some other EMI/RF shielding was required to project the control electronics as well as reduce device emissions.
DESIGN REQUIREMENTS
- Limited real estate; very thin media required
- Location directly under bulbs necessitated the need for a porous shielding media to allow for heat loss
- EMI/RF shielding of electronics components
KEY CUSTOMER REQUIREMENTS
- Airflow and EMI shielding
- Cost effective
- Engineering design and support
SOLUTION
Parker Chomerics designed a vent to cover the manufacturer’s light bulbs, which provided much needed air flow as well as EMI shielding.
Since traditional honeycomb media wouldn’t work for this application, we designed a 50 openings per inch (OPI) stainless steel mesh instead, which represented a unique manufacturing challenge being able to secure the flexible mesh to the vent frame. The frame was then grounded to the chassis via a CHO-SEAL® S6305 conductive elastomer in a groove.
CONCLUSION
Due to the unique design constraints on this application, traditional honeycomb vent media was not an option due to the limited amount or real estate to work with.
Our engineers came up with a 50 openings per inch (OPI) stainless steel mesh instead, which represented a unique manufacturing challenge being able to secure the flexible mesh to the vent frame. The frame was then grounded to the chassis via a CHO-SEAL® S6305 conductive elastomer in a groove.
EMI Shielded Air Ventilation Panels
Parker Chomerics EMI shielding air ventilation panels include a range of innovative products and configurations to deliver high performance shielding. Our shielded EMI air ventilation panels combine maximum shielding with minimal air flow resistance to provide optimal airflow for cooling electronic enclosures. These vents can be incorporated into enclosures where EMI radiation and susceptibility is a concern or where heat dissipation is necessary. This ensures long-term assembly performance. We also supply EMI fan filters for dust particle collection. Learn more.
