Character
1.Efficiency
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.
Application
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."

Plastic Artist-Acrylic Processing Technology

Acrylic can be used casting, injection molding, extrusion, thermoforming, laser engraving, laser cutting and other processes. Casting molding Casting molding for forming plexiglass sheet, bar and other profiles, that is, body-bulk polymerization method of forming profiles. After casting molded products need to be post-processed, post-processing conditions are incubated at 60 ℃ 2 hours, 120 ℃ for 2 hours. Injection molding Injection molding using suspension polymerization obtained pellets, molding in the ordinary plunger or screw injection molding machine. Process parameters include screw injection molding machine, plunger injection molding machine, barrel temperature, injection molding products also need to eliminate the internal stress treatment, processing in the hot air circulation oven at 70 ~ 80 ℃, processing time as the thickness of acrylic products, the general All about 4 hours. Thermoforming Thermoforming is the process of making plexiglass sheets or she...

What are the Basic Points that PC Diffuser Sheet needs to Master During the Construction Process?

In recent years, we can see that  PC Diffuser Sheet  has become a popular sheet, and it has also been favored by business users and enterprise groups in many fields. So, in the daily construction process of these plates, what aspects need to pay more attention to ensure the integrity of the project? Let's take a look at the basic essentials of PC diffuser in the construction process. As a  China Acrylic Sheet Manufacturer , share with you. The basic essentials of PC diffuser construction First of all, before the construction of the PC diffuser board, the staff must conduct a corresponding inspection of the surrounding environment, so as to determine the stacking of the board and the place where the related equipment is placed. To know that the construction preparation work can be said to implement the entire PC diffuser construction project and related processing and production operations, so everyone must make corresponding preparations in advance. Secondly, befor...
