Uniform surface brightness of panel light sources, ideal for inspection backlighting.
LUMITECHNO
The module of the light guide plate is hidden by the diffusion plate, and the uniformity of the surface has improved due to the diffusion effect of the diffusion plate, resulting in a surface light source.
The diffusion plate is ideal for use in inspection and research applications where LED panels are required to provide a uniform bright surface light source. Our LED panels utilize a light guide plate method, allowing the panel surface to emit light uniformly, making them suitable for various inspection and research applications. The light guide plate method involves shining light from LED chips onto a light guide plate (made of acrylic) that has a dot-patterned module printed on it, enabling efficient and even illumination of the entire panel surface with a minimal number of LED chips. The LED panel, with its low power consumption and high luminous efficiency, is an extremely eco-friendly light source. Additionally, by using a variable dimmer, you can adjust the brightness of the panel surface as desired, and we can also provide optimal surface light sources by drilling holes or modifying the light guide plate.

Inquire About This Product
basic information
The "light guide plate + diffusion plate specification" involves incorporating (or placing) a diffusion plate on top of the light guide plate to make the module invisible. The diffusion plate is made of 1.6mm thick resin. We also sell components such as light guide plates, diffusion plates, and LED chips. These can be integrated into various LED panels (LED light panels / LED light modules / LED light sheets) to create "light guide plate + diffusion plate specification LED panels." In the case of LED light panels, the thickness of the product does not change when integrated. (For LED light modules / LED light sheets, the thickness increases by 2mm due to the adhesive.) Depending on the type of inspection, you can also choose to brighten the surface of the panel or select from four types of surface color temperatures: 3K, 4K, 5K, and 6K (standard). The color rendering index is Ra80 or higher.

Company information
Our LED light panels have been on sale since 2007 using a light guide plate method. To maintain uniform brightness on the light source surface, the light guide plates are custom-made according to size, and by designing each one individually, we achieve a uniform light guide plate with a brightness uniformity of over 80%. For LED chips, you can choose from warm white at 3000K, white at 4000K, daylight white at 5000K, daylight color at 6500K, RGB chips, and variable color temperature LED chips ranging from 2700K to 6500K. However, the variable color temperature type is only available for sheet-type light guide plates and cannot be produced in panel type. The lifespan of the LEDs is approximately 40,000 to 50,000 hours, and there are facilities and stores that have been using our products for 10 years. They are widely adopted as menu boards in commercial facilities such as food courts and photo panels. As a light source, our products are appreciated for their high surface brightness uniformity, and products with a diffusion plate specification are used as light sources for visual inspections and image inspections by major manufacturers. Additionally, module-type surface light sources without a snap frame are ideal as alternative light sources for existing signs, architectural lighting, and display lighting.
