Extruded plastic lighting lenses are used by a wide range of home, commercial, industrial and medical applications and work by spreading or scattering light. Diffuser panels are affixed to either the bottom or side of a light fixture and are manufactured in clear and many diffused options. Acrylic light diffusers control the brightness of harsh lighting to create a soft lighting effect. They can also protect lighting fixtures from dust and help conserve energy by providing more even lighting that reduces the need for additional fixtures.

Polycarbonate diffusers and acrylic light diffusers are perhaps the most common types of diffuser lenses, though other materials may also be used. Extruded plastic lighting lenses come in a variety of shapes ranging from smooth to contoured covers. Our custom-made lighting diffusers are manufactured in over 50+ frosted or clear extruded acrylic and can have colors, texturing (such as ribbing and prismatic patterns), or films added to create a customized look.

What Are the Different Types Extruded Lenses?

Extruded plastic lighting lenses are manufactured in lay-in, snap-in, clip-on and other options to fit virtually any type of lighting. Common types of diffuser panels and plastic lighting lenses include:

  • Light diffusers and lenses
  • Display light covers
  • Architectural Lighting
  • Outdoor lighting lenses
  • Low Bay lenses
  • High Bay lenses
  • Industrial lenses
  • Retail lenses
  • Commercial lenses
  • Recessed lenses
  • Surface mount lenses
  • Refrigerated display lenses
  • And more

We Provide OEMs with Extruded Plastic Lighting Lenses and More

For over 70 years, Crescent Plastics has been extruding acrylic light diffusers for lighting applications. The lighting industry has recently begun to transition into more energy efficient LED fixtures, and we are part of this technology trend. We’ve been working with material suppliers and our customers to develop specific formulations for use in improved acrylic and polycarbonate extrusions, extruded LED lenses, LED light diffuser acrylic lenses, LED light lens covers, reflectors, and dust covers.

From standard acrylic lenses and polycarbonate lenses to UL fire retardant extruded plastic, we have helped OEMs with optimized material properties for optics, diffusion, and overall performance. 

Light Fixture Lenses

With our extensive materials knowledge and extrusion experience, Crescent Plastics can help you choose the right level of diffusion for your extruded LED lens and LED light diffuser acrylic lens profiles.

We provide unmatched design support for numerous applications, including considerations for material blend, diffusion, efficacy, aesthetics, fit, and cost. We offer quick turnaround times on tooling projects.

Crescent manufactures custom polycarbonate extrusions and acrylic extrusions with different levels of frost and diffusion from 50% to 94% light transmission. to provide the proper light transmission and hiding power for your extruded LED lenses. For additional “special effects,” we can also supply co-extruded LED lenses combining different colors or levels of diffusion.

Acrylic Extrusions

Our custom extrusions are the perfect solution for LED acrylic light diffuser lenses. At Crescent, we can provide extruded frosted acrylic lenses for any lighting application. Benefits of acrylic include durability, flexibility, and UV resistance.

Crescent Plastics manufactures acrylic lenses in several blends to provide the right amount of diffusion.  New unfrosted and frosted LED light diffuser acrylic lenses provide diffusion levels from 50% to 94% light transmission for resolving pixilation issues.

Polycarbonate Extrusions

Polycarbonate is popular for a variety of applications thanks to its great versatility. Polycarbonate extrusions exhibit high impact resistance, stiffness, moisture resistance, and heat resistance. At Crescent Plastics, we have years of experience producing polycarbonate extrusions, such as frosted polycarbonate lenses and diffused polycarbonate lenses, all designed specifically for LED light fixtures.

We fabricate clear polycarbonate extrusions in flame retardant (FR) grades which meets UL 94V-0 specifications at 1mm (0.040”) thickness. These polycarbonate materials are available in several different diffusion levels, ranging from clear at 91.5% light transmission to diffused with 63.7% light transmission at 1 mm thickness.

Custom Acrylic & Polycarbonate Extrusion to Suit Your Application

Crescent Plastics’ in-house tooling facility allows us to build all plastic extrusion and punch dies internally, which ensures optimum quality, timing, and cost minimization. Crescent is ISO 9001:2015 certified and offers acrylic and polycarbonate extrusions that are made to standards which exceed our competitors’ similar extruded products.

We can help reduce your costs by blending in color concentrates to find the right amount of diffusion at the right price for your extruded LED lens application. Different levels of diffusion can eliminate the need for costly coatings or Mylar inlays, which will save you money.

We also work with reflective acrylic and extruded polycarbonate materials. Benefits of these materials include:

  • ≈97% reflective surface
  • Replaces expensive reflective film and coatings
  • Improves lighting efficiency and design

We can also enhance the reflectivity of your extruded LED lens by applying foil materials to your profile.

Design Assistance for Extruded Plastic Lighting Lenses

Our experienced engineers can assist your team at any stage of your product’s development. For example, if you already have a completed prototype for an extruded LED light diffuser and are ready to move into production, we can move forward from that point.

For more involved projects, our engineers can take your rough sketch or blueprint and join forces with your team to create the best design possible. We also provide 3D printed samples that allow review of fit and assembly ergonomics. Our use of DFM methodology and our expertise in acrylic and polycarbonate extrusion ensure optimized quality and production economics for your LED light diffuser project.

Cost-Saving Strategies for Lighting Extrusion

We build all our extrusion dies and downstream tooling in-house, minimizing costs and saving time for our customers. Moreover, DFM methodologies optimize efficiency, which helps our customers get their extruded LED light diffuser products to market sooner, which increases company revenue.

State-of-the-Art Technology for Acrylic Light Diffusers

Light diffusion and transmission are two of Crescent Plastic’s strongest assets. Our engineers have the experience and knowledge to ensure that every extruded LED lens cover we produce allows the end user to create the ambience or lighting scheme that he or she desires.

Our use of online cutting technology enables us to hold tighter tolerances than traditional methods can, providing a more precise extruded plastic lighting lenses and diffuser panels.
