LED lighting has evolved over the years as innovative new components are used for wider application. It almost seems like for every lighting need, there is now an LED solution. The LEDs’ energy-saving properties, as well as their ability to change colour and temperature, have led to a better lighting experience with smart lighting solutions, healthy lighting options and the capabilities to illuminate small spaces.

Key LED components The various components that make up LEDs and the technology used in making these components are key to better product designs, which will result in the increased application of LEDs. Let us take a close look at these components.

1. Epoxy lenses: While protecting the LED semiconductor from outside elements, epoxy lenses are designed to allow light to escape in a way that the view angle can be focused or controlled. There are no loose or moving parts within the solid epoxy enclosure. Some guiding factors are the shape of the lens and reflector cup, the size and distance of the lens from the LED, etc. A wider viewing angle is achieved by positioning the LED closer to the nose of the lens. There are four main types of epoxy lenses that are commonly used.

Clear lenses: These produce the highest light output and the narrowest viewing angle. They are used for applications that require high intensity.

Tinted lenses: These are used to indicate the LED’s colour when switched on.

Non-diffused lenses: These are commonly used in backlighting applications in which the LED is focused on a translucent window in front of a panel. Such lenses with no glass particles produce a viewing angle of +/-12 degrees from the centre.
