The light diffusion plate characteristics , application and transmittance detecting method

The light diffusion plate is based on acrylic PMMA, PP, PS material and spherical particles diffusing agent ,by extrusion process to produce in clean room, a new type of light diffusion plate.
Plates one side is lattice microstructure matte surface, the other side is smooth and glossy or matte surface.With these unique structure,light transmitted through the sheet be fully diffuse,thus become both bright and pastel.In view of a point source (direct type) and a surface light source (light side) two structures plate lights have different requirements to the diffusion and the translucent of diffuser plate, JK microstructure diffuser plate has a high diffusion and high transmittance type two series to choose from:
 
Plate lights structure description:
 
Direct type LED plate lights also known as direct-injection plate lights,LED direct projection light ,by diffusion plate to homogenizing the light ,achieve high transmittance,also has good light shielding effect ,which has good whole body luminous surface lighting effects.
 
Side light LED plate lights is used in the world's advanced backlight technology,by the light guide plate, diffusion plate, the reflective film composition,the LED point, line source converted into uniform, soft surface light source, with a thin, energy-saving, high brightness characteristics.
 
JK Series the light diffusion plate application:
 
JK-90:thickness 2mm,transmittance over 90%,the haze 94%, suitable for distance from the light diffusion plate spacing 45mm around the direct type(back light) plate lights.
 
JK-85:thickness 1.5mm,transmittance over 90%,the haze 95%, suitable for distance from the light diffusion plate spacing 40mm around the direct type (back light) plate lights and side light panel lights.
 
JK-80:thickness 2mm,transmittance 85%,the haze 95%, suitable for distance from the light diffusion plate spacing 38mm around the direct type(back light) plate lights。
 
JK-70:thickness 1.5mm,transmittance 85%,the haze 95%, suitable for distance from the light diffusion plate spacing 38mm around the direct type(back light) plate lights side light panel lights.
 
JK-60:thickness 2mm,transmittance 80%,the haze 96%, suitable for distance from the light diffusion plate spacing 30mm around the direct type(back light)plate lights。
 
Diffusion plate optical value detection:
 
1. The illuminance meter, this instrument cheap, convenient and portable, but due to outside interference in natural light, the general test values will generally high. Such instruments only for reference, when comparing applicable, not as a precise instrument applies.
 
2. Transmittance the haze tester: this instrument during testing outside influence is small,so the result of the test is lower than illumination instrument, more accurate.Diffuser plate manufacturers generally make use of such instruments to test their products transmittance the haze.
 
3.Integrating sphere:integrating sphere test diffuser plate transmittance very accurate, almost free from the interference of the external environment, therefore, using the same plate test the data obtained are lower than the above two, because the instrument is more expensive, so only large lighting companies use this device detection transmittance。
 
Therefore, in view of use of detection equipment is not the same, the measured transmittance is not the same,when selecting diffuser be sure to ask what kind of equipment test for transmittance,so will not very different with their own expectations product.Remarks (above transmittance and the haze value is used Integrating sphere test).

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...

The Better Uses For Acrylic Sheet

Acrylic Sheet , using its moldable substance, lightweight temperament, and higher impact resistance, together with exceptional optical clarity, is employed in a vast selection of applications. Anywhere that a visit through surface that's both robust and appealing is required, throw acrylic sheet is your solution. In J.K OPTICAL PLASTIC frequently provide acrylic sheet to businesses in these sectors. BUILDING AND CONSTRUCTION Today’s buildings are defying the logic of physics, and as such need strong, durable materials. When that material also needs to be clear and have a high molecular weight, cast Acrylic Diffuser are the right choice. With so many thickness options and finishes, This sheet material provides building and construction professionals many options for their designs. COMMERCIAL AND STRUCTURAL GLAZING Because  Mirror Acrylic Sheet  is so strong, it makes the best option for structural glazing. Create weather and storm-resistant windows, large...

What is Diffuser Plate?

Diffuser Plate/Diffusion plate  cause a great deal of interference for light, regardless of the original design of the light distribution curve. The beam angle will trun into 160 ~ 176 °as long as it goes through the diffuser plate. So it will present a hazy feeling if you see from the side. Related products:  Diamond Diffuser Plate(K12 Pattern) According to the classification of optical principle, diffusion plate is only divided into two kinds, one is to make beam angle larger while another kind maintain the original angle. According to the material classification: glass, polystyrene (PS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate PET, PMMA, MMA .... etc. Translucent polymeric materials or synthetic materials can be made into diffusion materials for different applications.
