How to Know About The Important Differences Between Lighting and Lamp Guides
Light Guides can be made of optical-grade materials. They can be flat and smooth. They are designed to pass light from a light source to a point by total internal reflection. The guide can be used to pass light from an LED lamp on a pc board to the front panel. In other applications, it can be used to direct and collect light for backlighting LCD displays. The same principle can be applied to illuminate a grid pattern on a see-through window.
When choosing a light guide, there are three primary design concerns to consider. First, the guide must efficiently couple light from a light source to a specific point. Second, the guide must allow light to travel through it. Third, the light must be able to escape through the exit surface of the guide. Ultimately, a light guide must meet all of these criteria. For these reasons, it is important to choose a quality one.
