Light covers, also known as lighting guards, come in various shapes and sizes and are designed for protection and support as well as, in some instances, for aesthetic or functional purposes to either improve the look of the light or to increase the effects of the light by reflecting the light to create a larger or more impactful light source. Aesthetic covers are used to improve the appearance of a lighting fixture, for example, a diffused cover for a uniform appearance. Protective light covers are designed to provide protection against the front or rear of the light fixture. This can limit safety risks such as fire when downlighters are surrounded by insulation or to avoid a light fitting being hit or damaged during maintenance.
Some light covers are designed to work alongside downlights, for example, spotlights in a kitchen. The covers clip onto the rear of the light fitting to provide space and protection around it. Therefore it can be used alongside standard insulation products. The light cover provides space between the insulation and the light fitment to prevent overheating. Some covers are also suitable for use with other features such as public address loudspeakers.
Light covers are typically made of either plastic or fabric, depending on their purpose though some covered metal frame covers are found where a more robust solution is required.
