J.K acrylic diffuser sheet, also named PMMA diffuser,Lighting diffuser, acrylic sheet or something others, is a translucent PMMA product with a textured surface on one side or both side specifically designed for LED panel light , downlight and so on. It features a unique combination of high light diffusion and high light transmission through a combination of optimized surface texture and advanced diffuser technologies. When compared to other acrylic diffusing products such as glass and PS, and PP sheets, J.K diffuser sheet has superior impact strength and toughness. Other surface textures are available for additional design options.
J.K acrylic diffuser, extruded sheet product was developed specifically as a diffusion lens for LED lighting. It offers distinct light diffusion levels that can be matched with other design elements to help achieve the desired lighting qualities for different fixture designs. The technology behind the sheet diffusion properties, helps minimize hot spots caused by intense LED lighting.
We can tailor to customer's requirement and offer laser cutting service to meet some special demands.
1,Translucent with One side matt, another side smooth;
2, Translucent with one side matt, another side orange peel texture.
Acrylic diffuser enable high efficiency extraction of light from a luminaire without sacrificing performance. Transmission well in excess of 90% is typical, and luminaire dependent efficiency can be even higher.
2.Light source hiding ability
Acrylic diffusers offer outstanding hiding of LED and fluorescent light sources, with excellent color mixing. The diffusers solve the most difficult LED hiding problems while maintaining excellent efficiency.
3.Inreases light uniformity throughout the lighting diffuser;
4.Simplify design consideration for new fixtures and for retrofit conversions to LED's;
5.Choose the best option for different fixtures' performance requirements.
Market research showed a need for diffuser sheet with different levels of light diffusion to meet various fixture performance requirements. "Some designs, for example, may want a low level of diffusion to soften the edges of emitted light. Others may need more light diffusion to reduce direct glare. Also, variables such as the LED-to-lens distance and the LED matrix spacing affect the optimal light diffusion. While diffusion and light transmission are directly associated, having these diffusion options allows the light fixture designer the ability to achieve the lighting qualities they desire for a specific fixture."
J.K Acrylic diffuser with different levels of light diffusion offer more possibility to design versatility, it simply mean more possibilities to find a diffuser that works best in the overall design, This is important especially when converting existing fixtures to LED lighting, where the diffusing sheet has to work well with design elements that already exist."
