Luminit Recently Announced a New Edge-Lit Uniformity Tape and a New Direction Turning Film

Luminit LLC, a privately held high technology company specializing in custom and standard holographic light shaping diffusers, adds Edge-Lit Uniformity Tape (EUT) to its unique lineup of Light Shaping Diffusers®. EUT is an inexpensive and effective solution for solving common problems associated with widely-spaced LEDs. The company also introduces a new Direction Turning Film (DTF) to its growing line of optical technologies and products.

Edge-Lit Uniformity Tape:
EUT uses Luminit’s patented diffusion technology that transforms and improves light for a brighter, more uniform panels. With a transmission greater than 88%, EUT allows display and lighting manufacturers to achieve better uniformity and brighter displays and fixtures without increasing the number of LEDs.

“The more LEDs placed within a display, the better the uniformity will be,” notes Suleyman Turgut, Director of Sales at Luminit, LLC. “The down side to this is an increase in the bill of materials. Our Edge-lit Uniformity Tape achieves better uniformity without increasing the number of LED lights which can result in significant cost savings for manufacturers.”

Luminit’s Edge-Lit Uniformity Tape uses an optically clear adhesive backing that can easily be applied directly to the side of the light guide plate during the assembly process. On the tape facing the light source are highly elliptical LSD microstructures that spread the light to reduce hot spots, dark spots and other non-uniform characteristics that can be visible on the edges of LED flat panel TVs and edge-lit lighting fixtures.

According to Luminit, optical characteristics of EUT include a transmission frequency greater than 88% and lighting panel uniformity greater than 80%. Light spread angle is +/- 70° from the normal.  EUT is available in 50-meter rolls and widths ranging from 2.8 mm to 7.8 mm.

Direction Turning Film:
The unique light-bending film enables off-axis placement of an incoming beam to create an optimal angle for the viewer and provides a simple solution to lighting challenges. Allowing a 20° shift in the angle of a light source, Luminit Direction Turning Film offers lighting designers and engineers more flexibility on how and where a light beam is directed.  

“Our Direction Turning Film solves a number of lighting and display challenges faced by engineers and designers,” notes Suleyman Turgut, Director of Sales at Luminit, LLC. “DTF allows more beam control and can produce dramatic results particularly when used on downward recessed lighting to achieve more wall washing.”

Ideal for LED light sources that utilize secondary optics, DTF includes microscopic, asymmetrical prismatic structures embedded on the film that change the light beam direction. DTF can redirect the light beam toward the wall, enhance lighting in pathways and stairways, and redirect pool lighting for better, more uniform coverage. In addition to solving common problems associated with interior and exterior lighting structures, Luminit DTF can be incorporated into display panels such those used as in avionics to allow optimum views for both pilot and co-pilot.

Luminit DTFs are available as simple 20° direction turning films or can be combined with Light Luminit Light Shaping Diffuser® to homogenize, redirect, and increase the beam angle of a light source.
