Polycarbonate sheet offers a number of advantages for lighting applications including: Special grades of polycarbonate are engineered to meet even the most stringent flammability requirements for aircraft and mass transit lighting. If you see most of the light on the back side of the object, and it's mostly white, then you're good. Polycarbonate sheet and film have good light transmission, excellent diffusion of LED hot spots, and offer impact resistance along with good heat resistance. Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. In nature, the sun on a bright cloudless day is a good example of light from a single point source. 98.0%. In addition to eliminating obvious light source points, light diffusion materials can be used to tint the color of the transmitted light.

Welcome Back! These include the type of light source being used, the potential for impact, flammability requirements, outdoor exposure, and the service temperature range. I use this guide in my graduate level class at SVA called "Making Studio" in the Products of Design program-- the project is to design a plush night light, and explores LED diffusion using soft materials. The quality of the plastic diffusers is because of the use of nanotechnologies. My students are mostly new to electronics and always have a lot of fun exploring different diffusion techniques and materials. These systems rely on high resolution cameras being able to detect contrast between the parts being inspected and the surrounding background. Which plastics are the best choices for diffusing LED light? For something that you can purchase at nearly any store for $5-$8, a frosted shower curtain can really pack quite a punch as far as diffusion goes. $14.99 $ 14. However, LEDs can be particularly challenging for lighting designers since LEDs create “hot spots” of focused light that can detract from the visual appeal of a fixture. They are available in many different styles, thicknesses and transparencies for different needs, and are usually used for lay-in fixture and other lighting applications. Special grades of, LED-Diffusing Acrylic Eliminates Hot Spots, TUFFAK® Lumen XT for Brighter Railcar Lighting, Makrofol® LM Film for Electronic Control Panels, TUFFAK® Lumen XT for Machine Vision System, Architectural Lighting Manufacturer Struggles with Fabrication Timelines, Lighting Solution Provides Enhanced Diffusion for Medical Device Inspection, The highest light transmission of any plastic material, Naturally UV stable for outdoor use (and available in grades with enhanced UV stability), lighting applications, particularly for mass transit. Some systems can even determine if parts are within specified dimensional tolerances. With the diffusers, you get minimum light loss, high diffusion and colour purity. Since the light color directly influences what colors the object can reflect (as you may remember from the Colors chapter) it has a significant impact on the visual output.. We can easily change the light's colors over time by changing the light's ambient and diffuse colors via sin and glfwGetTime: Machine vision system manufacturer chooses durable TUFFAK® Lumen XT polycarbonate sheet for LED light diffusers.

While you can easily buy a light strip diffuser they are also quite easy to make and don’t require much other than something to diffuse the light. LEDs are long lasting, energy efficient light sources. Makrofol® LM polycarbonate films offer unsurpassed design flexibility for light diffusing applications. Remote downconverters such as phosphors or quantum dots that are physically separated from blue light-emitting diode (LED) chips can strongly enhance the luminescence efficiency of solid-state lighting (SSL) and liquid-crystal displays (LCDs) because of their reduced light reabsorption. Acrylic sheet is used for a wide range of lighting applications including: Acrylic has a number of benefits for lighting applications: LED light diffusing acrylics including OPTIX® LD, OPTIX® 95 LED, OPTIX® Frost LED, and Plexiglas® Sylk are engineered to diffuse hot spots while maintaining very high light transmission. These materials have textured surfaces and LED light diffusing additives to hide hot spots while still maintaining high light transmission. As a uniform light, the diffuser has functions of shielding light source, LGP outlets, and defects. Used in such items as LED lighting covers and for ensuring privacy with glass partitions, these coatings retain high brightness (light transmittance) while preventing light sources and people on the other side of the glass from being seen. Our plastics experts can answer your questions and advise on LED lighting applications. This specialty acrylic sheeting is the ideal material for signs and channel letters and any other backlit application requiring light diffusing properties. LEDs are long lasting, energy efficient light sources. Acrylic - generally has superior optical properties compared with polycarbonate. ©2021 Curbell Plastics, Inc. All rights reserved.
