LRA / Custom Dual-Mode Day and NVIS Night LED Rail / Design Reference

(0 review)

Custom rail with separately driven day and filtered night channels. Define optical isolation, drive leakage, source/filter geometry and thermal design. Check phosphor fluorescence from unpowered day LEDs. No completed or qualified assembly is represented.

Application development required. Final configuration is established through a reviewed drawing and specification.

Representative illustration; configuration and dimensions are defined by the application drawing.

Pricing is available by quotation. Save products to your Interest List to request a quote for several items, or contact us about this product.

Application and configuration

Use this design family when developing, enhancing or repairing an LCD backlight. Mechanical size alone does not establish compatibility: emitting height, light-guide coupling, driver loading and thermal contact must also match.

Define the rail assembly

Develop a drawing covering length, width, height, mounting features, LED pitch and orientation, emitting-center height, connector and pinout, harness, polarity and thermal interface. Specify LED/color bins, string topology, regulated drive current, dimming range and operating temperature. Rails are tracked by lot.

Dual-mode and NVIS development

Define daylight and night channels separately, including the required NVIS class and output color. Match filters to the actual LED spectrum and operating conditions; control unfiltered bypass light, electrical leakage and optical coupling between channels. Verify the complete display in each operating mode.

Retrofit review

Provide the LCD model and revision, original rail or lamp information, available cavity dimensions, light-guide edge geometry and driver information. Sample inspection may be needed to establish fit. No specific LCD compatibility has been verified for this reference.

From reference to a controlled part

Start with the application and available space. Develop a drawing with custom dimensions and performance specifications, review the proposed configuration, and evaluate samples where needed. Record the approved drawing revision and acceptance criteria for the supplied part. Availability and final configuration are confirmed during quotation.

Application data

Configuration-specific spectral, mechanical and electrical data is reviewed with the proposed drawing. Use Contact Us or add this reference to the Interest List to identify the application and requested format.
