On a daily basis, we work with custom color LEDs, fiber-optic panels, diffusion materials, and opacity solutions including black gasketing materials to provide precise control of lighting panels. Our engineers can help you select the backlighting system that is ideal for your product, delivering assemblies that help drive a great brand impressions and meet critical design goals.
Light Emitting Diodes (LEDs)
LEDs provide a huge range of options for design engineers – traditional, side firing, NVIS, and multi-color (bi-color and tri-color). They are reliable, affordable, and compact, so they are also very common. The challenge is to use them to their best advantage. We can help you manage the bright (Hot) spots that can arise from these single point sources by introducing diffusing layers and customized graphics and materials into the assembly.
Our engineers are well versed in both traditional and woven flat panel applications. These fiber optic technologies allow our customers to illuminate key areas of a panel or switch with fewer LED’s, resulting in reduced power consumption. Depending on the application, we can help design solutions that strike the balance between precision lighting, compact, low profile assemblies, and cost-effective components.
Light Guide Films
Light Guide Films, or Light Guide Layer (LGL) technologies, can serve as an economical alternative to woven flat panel fiber optics. Using LGL, we imprint light-diffusing plastic materials in a manner that manages and directs light to specific areas and in precise ways. It can be a very affordable approach, especially when you work with a supplier experienced with these technologies. It also provides a great deal of control and flexibility for design engineers looking to optimize the user experience.
Custom Silicone Membrane Layers
Also referred to as light piping, this approach can be a smart solution for delivering light to a membrane switch or other user interface assembly. Custom silicone membrane layers are highly efficient, and offer a range of options for managing and directing backlighting. We offer a wide variety of standard light pipe techniques as well as custom solutions made from select materials that can optimize performance based on your unique application.
Solid State Electroluminescent (EL) Lamps
These are typically assembled with a graphic overlay over an EL panel. The light is smooth and even, the lamps are thin and compact, and there is minimal heat leakage. Their AC/DC power requirements need to be supported, so they aren’t ideal for every application, but our engineers have the experience and know-how necessary to identify when EL is the right solution.
NVIS LEDs are a type of LED (light-emitting diode) that are specifically designed for night vision imaging systems (NVIS). Military, Law Enforcement, and Search and Rescue personnel using night vision goggles (NVG) must be able to read illuminated displays without the displays interfering with the performance of the goggles. The displays must also be readable to those not using night vision.
NVIS LEDs can be easily incorporated into various components such as instrument clusters, indicators, panels, buttons and switches. These LEDs are more resilient than traditional displays and consume less power due to their reduced luminance requirements.
They are typically used in military and aerospace applications, where maintaining the ability to see in low-light or no-light environments is critical to mission success. These specialized LEDs are designed to emit light in a specific wavelength range and are carefully calibrated to meet the strict requirements of various military and industry standards.
