Products Description
The difference between single-sided / double-sided microstructured diffuser film and ordinary diffuser film
Common Diffuser Film Structure
Structure: It's typically based on PET (polyethylene terephthalate) with a layer of diffusing particles coated on the surface. The PET layer provides mechanical strength. The diffusing surface is bonded with an acrylic resin bead layer using a binder to diffuse light. The back surface also has a bead layer, but its density is lower than the diffusing surface to prevent adhesion to the light guide plate.
Common Diffuser Film Principle
Principle: Particles of varying sizes within the diffusion film scatter the light reflected from the light guide plate surface, creating a uniform mist effect. This scattering mechanism relies on the precise arrangement of particles with different diameters, which disrupt the original light path to disperse light energy evenly. Meanwhile, the refraction and reflection processes within the diffuser material further atomize the light source, transforming concentrated light beams into a soft, diffused glow.
single-sided / double-sided microstructured diffuser film
Typically, a diffuser's ability to hide bright spots is inversely proportional to its light efficiency; the stronger the ability to hide bright spots, the lower the light efficiency. The single-sided / double-sided microstructured diffuser film overcomes the limitations of traditional diffusers in both bright spot hiding and light efficiency, achieving both high light efficiency and high bright spot hiding.
single-sided / double-sided microstructured diffuser film
Ordinary diffusers are prone to color temperature drift, which can be observed in direct-lit LED luminaires, typically manifesting as a warm center and a cool edge. In direct-lit display backlights, this phenomenon manifests as mura.
• Using single-sided or double-sided microstructured diffuser films can effectively eliminate color temperature drift in LED luminaires and mura in direct-lit backlights.
| single-sided / double-sided microstructured diffuser film | Common Diffuser Film |
|---|---|
| Relatively concentrated light distribution- Enhances effective illumination light and reduces high - angle light (glare)- Can achieve an ultra - wide diffusion angle | Large - angle Lambertian light distribution |
| Clear and transparent material. Light diffusion is achieved through the refraction of microstructures, with almost no internal light loss | Scattering particles are added to transparent plastic materials. While achieving the effect of hiding high - light spots, there is significant light loss |
| Wide range of diffusion angle options:- 5, 10, 15, 20, 30, 40, 55, 80 | Typically "120°" Lambertian distribution |
| Better light mixing effect- Avoid blue/red light shift- Eliminate the Mura phenomenon of direct - lit backlight- Especially important for lens concentrating or reflective concentrating | Poor light mixing effect, easy color temperature drift, and uneven color |
Single-Sided / Double-Sided Microstructured Diffuser Film
Solve the problem of mixed light in lighting
Conventional diffusers used for lighting exhibit color nonuniformity depending on the light angle, resulting in haloing and color nonuniformity.
• Using Single-Sided / Double-Sided Microstructured Diffuser Film eliminates haloing at the edges of the spotlight's illumination area and provides a uniform illumination pattern.
Conventional diffusers are prone to color temperature shift, which can be observed in direct-lit LED fixtures, typically manifesting as a warmer center and cooler edges. In direct-lit display backlights, this manifests as mura.
• Using single-sided/double-sided microstructured diffuser films can effectively eliminate color temperature shift in LED fixtures and mura in direct-lit backlights.
Single-Sided / Double-Sided Microstructured Diffuser Film Installation Notes
Single-Sided / Double-Sided Microstructured Diffuser Film produces different effects when used from the front and back. Typically, the (primary) microstructured side faces away from the light source.
However, for some applications, such as focusing lenses and strip lights, the (primary) microstructured side needs to face the light source.
RINA TECH recommends experimenting with both sides of the single-Sided / Double-Sided Microstructured Diffuser Film when designing a luminaire. Comparing the appearance and light efficiency will determine whether the microstructured side faces inward or outward.
To minimize errors during luminaire assembly, RINA TECH recommends marking the notch on the single-Sided / Double-Sided Microstructured Diffuser Film to prevent it from being installed upside down. See the image to the right.
Application of Single-Sided / Double-Sided Microstructured Diffuser Film
Downlights, reflector spotlights, floodlights, etc.
The light source itself is at a small angle (e.g., 5 degrees, 10 degrees, 25 degrees)
• Reflector or focusing lens
• Round downlight or linear spotlight
Direct downligh
