LGP Sheet

Function

The primary function of an LGP sheet is to evenly distribute and guide the light emitted by LEDs across the surface of the lighting fixture. It works by internally reflecting and diffusing the light, ensuring uniform illumination without hotspots or glare.

Construction

LGP sheets are typically made from clear or translucent acrylic or polycarbonate materials. They feature a pattern of microstructures, such as prisms or dots, on one or both surfaces. These microstructures are designed to efficiently capture and redirect the light rays, allowing for maximum light transmission and uniformity.

Light Extraction

LGP sheets are engineered to extract light efficiently from the LEDs embedded within the lighting fixture. They often feature a combination of diffusing and reflective elements to enhance light extraction and minimize light loss.

Customization

LGP sheets can be customized in terms of size, shape, thickness, and microstructure pattern to suit specific lighting requirements and design preferences. Different patterns and configurations can be employed to achieve various lighting effects, such as direct illumination, edge lighting, or backlighting.

Energy Efficiency

By effectively distributing and controlling the light output, LGP sheets contribute to energy-efficient lighting solutions. They help maximize the luminous efficacy of LEDs by ensuring that a higher percentage of light is directed toward the desired target area, reducing wasted light and energy consumption.

Applications

LGP sheets are commonly used in various lighting applications, including:

LED Panel Lights

LGP sheets are frequently employed in LED panel lights to achieve uniform surface illumination for applications such as office lighting, retail displays, and architectural lighting.

LED Light Boxes

LGP sheets are used in LED light boxes for signage, advertising, and display purposes. They ensure even backlighting and consistent brightness across the display surface.

LED Troffer Lights

LGP sheets are utilized in LED troffer lights to distribute light evenly across the ceiling area, providing ambient lighting in commercial and institutional settings.

Architectural Lighting

LGP sheets are incorporated into architectural lighting fixtures, such as wall washers, cove lights, and linear lighting systems, to achieve specific lighting effects and ambiance.
