Products Description
Diamond Pattern Prism Plate Product Introduction
Diamond Pattern Prism Plate is a specially molded optical sheet with a surface covered with regularly arranged diamond-shaped prisms. Its core function is to achieve efficient light control through the optical refraction and reflection of the diamond pattern. This product uses optical-grade PMMA (polymethyl methacrylate), PC (polycarbonate), as the main substrate, combining excellent optical performance and mechanical stability. Thickness (typically 0.1mm-5mm), diamond pattern specifications (side length 0.05mm-5mm), and light transmittance (generally 85%-95%) can be customized according to application requirements.
In terms of applications, Diamond Pattern Prism Plate, due to its light homogenization, focusing, and diffusion effects, is widely suitable for LCD backlight modules, LED lighting fixtures, solar photovoltaic modules, automotive interior optical components, advertising light boxes, and other scenarios.
Diamond Pattern Prism Plate Production Process
1. Substrate Selection and Pre-treatment: High-transmittance, low-impurity optical-grade substrates are selected. Moisture is removed from the raw materials using a dehumidifying dryer. The dried raw materials are then fed into a screw extruder to form a uniform melt.
2. Precision Embossing: The molten substrate is conveyed between embossing rollers and cooling rollers. The surface of the embossing rollers is engraved with a diamond pattern steel mold matching the target product. The pressure between the rollers presses the diamond pattern onto the surface of the melt.
3. Cutting and Trimming: According to customer order requirements, CNC cutting machines are used to cut the shaped boards to the specified dimensions. Then, trimming equipment removes burrs and defects from the edges of the boards.
4. Optical Performance Testing: A transmittance meter, gloss meter, and optical microscope are used to sample and test the products, focusing on transmittance, pattern clarity, and surface flatness.

The main role of the Diamond Pattern Prism Plate
1. Superior Optical Control Capabilities: The diamond-patterned structure enables directional focusing and uniform diffusion of light, effectively improving light source utilization. In display scenarios, it can increase brightness uniformity by 20%-30%, and in lighting scenarios
01
2. Excellent Mechanical Properties: Products based on PMMA or PC possess high impact resistance and weather resistance. They can withstand certain external impacts without easily breaking and can adapt to a temperature range of -30℃ to 80℃,
02
3. Lightweight and Easy to Process: Compared to traditional glass prisms, this product has a density of only 1/2 to 2/3 that of glass, making it much lighter. It can also be easily processed into different shapes through simple processes such as cutting, bending, and bonding

FAQ
1. Can Diamond Pattern Prism Plates be used in outdoor environments?
Yes. For outdoor applications, Diamond Pattern Prism Plates with a more weather-resistant PC substrate can be selected. Their surface can be additionally coated with an anti-UV coating, effectively resisting ultraviolet radiation and preventing aging, embrittlement, or decreased light transmittance after long-term outdoor use. This makes them suitable for outdoor applications such as solar photovoltaic systems and outdoor advertising light boxes.
2. Can the diamond pattern specifications of Diamond Pattern Prism Plates be customized?
Absolutely. During production, the diamond pattern can be customized by changing the embossing rollers with different pattern parameters, including the side length (0.05mm-5mm), angle (usually 60°/120° or 90°/90°), and depth of the diamonds, to meet the optical requirements of different scenarios. For example, precision display scenarios require small-sized, fine patterns, while outdoor lighting scenarios can use large-sized, coarse patterns.
3. What is the difference between Diamond Pattern Prism Plates and ordinary diffuser plates?
The core difference lies in the optical mechanism and effect: ordinary diffusers achieve light homogenization through light scattering by internal microparticles, but this results in some loss of luminous flux; while the Diamond Pattern Prism Plate, through the refraction and reflection of diamond prisms, achieves both light homogenization and light focusing, resulting in higher light utilization and a more significant increase in brightness, making it more suitable for scenarios with high requirements for both brightness and uniformity (such as LCD backlighting).
4. How to clean stains on the surface of the Diamond Pattern Prism Plate?
Use a gentle cleaning method to avoid damaging the diamond pattern: It is recommended to use a lint-free cloth dampened with medical alcohol or a special optical cleaner with a concentration of less than 50%, and gently wipe in a clockwise or counterclockwise direction, avoiding back-and-forth rubbing; do not use hard-bristled brushes, sandpaper, or strong corrosive cleaners (such as gasoline or acetone), as this may scratch the surface or damage the substrate.
