Products Description
Product Introduction of Light Mixing Angle Diffuser Sheet
The Light Mixing Angle Diffuser Sheet is a functional sheet material focused on optimizing optical performance, primarily used for efficient light mixing and precise angle control. This product is mainly manufactured using two high-quality base materials:
PMMA (polymethyl methacrylate) and PC (polycarbonate). Both materials possess excellent optical transmittance, weather resistance, and mechanical strength, making them suitable for various applications.
In terms of specifications, the product offers a diverse range of thicknesses, with PC base materials typically ranging from 0.25mm to 6mm, and PMMA base materials typically ranging from 0.65mm to 6mm, meeting the requirements for different equipment regarding sheet thinness or structural strength.
Custom sizing is also available, allowing for precise cutting and production based on specific customer application scenarios and equipment models. This product is widely applicable in various fields, including LCD displays, lighting fixtures, and optical instruments.
Advantages of Light Mixing Angle Diffuser Sheets
1. Efficiently Concentrates Effective Light:
Through meticulous control of the surface micro-lens structure and the precise refraction of the micro-lenses, the product can directionally converge dispersed light, significantly improving the utilization rate of effective light, reducing light loss.
2. Clearly Defined Lighting Boundaries:
It effectively eliminates high-angle scattered light, avoiding the blurring of boundaries caused by excessive light diffusion, making the boundaries of the illuminated area clearer and more regular, enhancing the overall layering.
3. High-Quality Substrate Guarantees Performance:
Using PMMA and PC, two high-transparency base materials, the product not only has high light transmittance but also possesses good impact resistance, temperature resistance
4. Strong Customization and Adaptability:
Supports full customization of thickness and size, accurately matching the installation and usage requirements of different devices, significantly increasing the product's applicability and reducing customer adaptation costs.
Manufacturing Process of Light Mixing Angle Diffuser Sheet
1. Substrate Selection and Pre-treatment:
Based on customer requirements, the appropriate PMMA or PC substrate is selected. The substrate is then cleaned and dried to remove surface oil, impurities, and moisture, ensuring the cleanliness of the substrate surface and laying the foundation for subsequent processing.
2. Microlens Structure Design and Mold Preparation:
Based on the required optical performance, the dimensions and arrangement of the microlenses are designed using optical simulation software. Then, precision machining techniques are used to create the corresponding molding mold, ensuring that the microstructures on the mold surface accurately replicate the design requirements.
3. Molding Process:
The pre-treated substrate is placed in the molding equipment. Through extrusion molding or calendering processes, the substrate is tightly bonded to the mold under high temperature and pressure,
4. Cooling and Shaping:
The molded sheet is subjected to gradient cooling treatment to prevent stress and deformation caused by rapid cooling, ensuring the flatness and dimensional stability of the sheet.
5. Cutting and Trimming:
According to the customer's customized size requirements, the sheet is cut using precision cutting equipment. The cut edges are then trimmed and polished to remove burrs and ensure smooth and neat edges.
6. Optical Performance Testing:
Using professional optical testing equipment, the product's core indicators such as light transmittance, light diffusion angle, and effective light concentration are tested to ensure that the product meets the design standards.

FAQ
Q1: What base materials are supported for the Light Mixing Angle Diffuser Sheet? What are the differences between the two base materials?
A1: Two base materials are supported: PMMA and PC. The difference is that PC base material has stronger impact resistance, a wider temperature range, and a thinner standard thickness (starting from 0.25mm); PMMA base material has slightly higher light transmittance and is more cost-effective, with standard thicknesses starting from 0.65mm. Customers can choose the appropriate base material based on the impact strength and temperature requirements of the application environment.
Q2: Are there any minimum or maximum size limitations for the Light Mixing Angle Diffuser Sheet?
A2: Theoretically, there are no strict minimum or maximum limitations; it can be customized according to the customer's actual needs. The standard customized size range covers the needs of most general-purpose equipment. For extra-large or extra-small special sizes, please communicate with our technical team in advance to confirm feasibility. We will adapt according to our production equipment capabilities.
Q3: What are the main applications of the Light Mixing Angle Diffuser Sheet?
A3: It is widely used in scenarios requiring precise control of light angle and improved lighting effects, such as LCD backlight modules, LED lighting fixtures (such as panel lights, spotlights), optical instruments, medical equipment lighting, and advertising light boxes.
Q4: What installation precautions should be taken when using the Light Mixing Angle Diffuser Sheet?
A4: During installation, care should be taken to avoid scratching the microlens structure on the surface of the sheet. It is recommended to wear dust-free gloves during operation; ensure a clean installation environment to prevent impurities from adhering to the surface of the sheet and affecting the optical effect; in addition, choose an appropriate fixing method based on the characteristics of the base material to avoid excessive compression that may cause deformation of the sheet.
Q5: What is the approximate lifespan of the Light Mixing Angle Diffuser Sheet?
A5: Under normal operating conditions (avoiding high temperatures, direct strong UV radiation, and severe impact), the lifespan of PMMA base material products can reach 5-8 years, and the lifespan of PC base material products can reach 8-12 years. The specific lifespan will be affected by the operating environment. It is recommended to choose the appropriate base material and protective measures based on the actual scenario.
