1.What is a LGP(light guide plate)? What’s its function in cabinet light with LGP?
A light guide plate (LGP) is a transparent thin plate made of optical-grade acrylic (PMMA) or polycarbonate (PC) material. After being processed using laser dotted or screen printing dot techniques, it can uniformly guide side light from LED light sources across the entire surface, achieving a diffuse light source effect.
In cabinet lighting, the primary functions of a light guide plate include:
Achieving uniform illumination: The microstructures within the light guide plate effectively disperse light, preventing bright spots or dark areas, ensuring that the entire cabinet area is illuminated with soft, even light.
Supporting ultra-thin design: LGP uses a side-lit light source, which can provide full illumination with one or two LED light strips, significantly reducing the thickness of the lighting fixture. This makes it ideal for use in space-constrained kitchen cabinets, wardrobes, display cabinets, and other applications.
Energy-efficient and high-performance: Light guides improve light energy utilization, providing sufficient brightness even at lower power levels. This extends the lifespan of the lighting fixture while reducing energy consumption.
Aesthetically pleasing and sleek: Cabinet lights using LGP eliminate the need for traditional reflectors and diffusers, resulting in a simpler overall structure and a lighter, thinner lamp body, meeting the aesthetic demands of modern cabinets for “invisible light sources.”
Therefore, light guides have gradually replaced traditional diffusers and have become one of the core components in high-end cabinet lighting and custom furniture lighting.
2. What are the core advantages of led light guide plate for cabinet lights?
Thin and lightweight design: Light guide plates are extremely thin, making them suitable for the confined spaces inside cabinets.
Even brightness: Light distribution is balanced, with no obvious bright spots or dark areas.
Energy-efficient and environmentally friendly: Higher luminous efficiency reduces energy consumption.
Customizable: Light guide plates can be customized to different specifications based on cabinet dimensions and structure.
Such light guide plate-based cabinet lighting fixtures are increasingly becoming the mainstream choice for high-end kitchen and custom furniture design.
light guide plate typical application in cabinet lighting
Due to their ultra-thin and uniform light emission characteristics, light guide plates are widely applied in the following cabinet lighting scenarios:
Under-cabinet lights in kitchens: Installed at the bottom of hanging cabinets to illuminate the countertop, enhancing kitchen functionality and aesthetics.
Built-in wardrobe lights: Embedded in the side panels or top of wardrobes, providing soft lighting to facilitate finding clothes.
Display cabinet lights: Used in glass display cabinets or shelves, evenly illuminating exhibits to create a high-end atmosphere.
Drawer lighting: Integrated with motion sensors, automatically illuminating when drawers are opened, enhancing user experience.
Mirror cabinet or bathroom cabinet lights: Light guide panel are installed behind mirrors or inside cabinets to provide soft, shadow-free lighting.
How to choose the right LGP panel for cabinet lights?
When selecting LGP acrylic sheet for cabinet lights, pls follow below aspects:
Thickness: Common thicknesses include 3mm, 4mm, etc.
Light guide plate optical dot design: Laser-dotted or screen-printed points enhance light distribution.
Light source layout: Edge-lit designs are more suitable for ultra-thin fixtures.
Material selection: Common materials include PMMA (acrylic) and PS (polystyrene). PMMA offers better light transmission but is slightly more expensive.
As demands for cabinet lighting performance and space utilization continue to rise, cabinet lights utilizing light guide plate (LGP) technology are increasingly becoming the market mainstream. It offer advantages such as uniform lighting, energy efficiency, ultra-thin aesthetics, and are suitable for various customized lighting scenarios, making them an ideal solution for modern residential and commercial furniture lighting.
