LED Light Bar with Optical Lens – High-Power LED Strip with Lens for Lightboxes
LED Light Bar with Optical Lens for Lightboxes
BOOTH LIGHTS' LED Light Bars with Optical Lens are precision-engineered for SEG fabric lightboxes, backlit signage, and commercial display cabinets. Unlike standard LED strips, our High-Power LED Strips with Lens incorporate a secondary optical lens over each LED chip — controlling the beam angle and directing light exactly where it's needed for maximum panel uniformity.
Why Optical Lens Matters for Lightbox LED Modules
A bare LED emits light in a wide, uncontrolled pattern. Without a lens, light from a side-mounted bar scatters unevenly, creating bright zones near the LEDs and dark areas toward the center of the panel. Our Asymmetric Lens LED Modules solve this by reshaping the beam into a precise asymmetric pattern — typically 9°×50° or 15°×60° — that floods the diffusion panel evenly from edge to edge.
The result: uniformity ratios above 85% across the entire lightbox face, even in shallow-depth frames where standard modules would show hot spots.

What Is an Asymmetric Lens LED Module?
An Asymmetric Lens LED Module uses a lens profile that is not symmetrical around the optical axis. Instead of projecting light equally in all directions, the lens concentrates the beam in one direction — toward the center of the lightbox panel — while limiting light loss toward the frame. This is the most efficient design for edge-lit and side-lit lightbox applications, where the LED bar is mounted at the perimeter and must illuminate a panel that extends only in one direction from the light source.
Applications
- SEG fabric lightboxes — trade show backwalls, hanging banners, counters
- Backlit signage panels — retail, airport, hotel, and corporate environments
- Display cabinets — jewelry, cosmetics, and luxury retail showcases
- Billboard and cabinet sign illumination — outdoor and indoor advertising displays

Frequently Asked Questions
What is an LED Light Bar with Optical Lens?
An LED Light Bar with Optical Lens is a rigid LED bar where each LED chip is covered by a precision-molded secondary lens. The lens controls the beam angle and direction, improving light uniformity across the lightbox panel compared to bare LED strips.
What beam angle do your optical lens LED bars use?
Our LED Light Bars with Optical Lens are available in 9°×50° and 15°×60° asymmetric beam profiles. The narrow angle (9°) controls light spread along the bar length, while the wide angle (50°–60°) projects light across the panel depth.
What is an asymmetric lens LED module?
An asymmetric lens LED module uses a non-symmetrical optical lens that directs light preferentially toward the lightbox panel rather than equally in all directions. This maximizes efficiency and uniformity for edge-lit and side-lit lightbox applications.
Do I need an optical lens for my lightbox?
If your lightbox is shallow (depth under 3 inches / 75mm), an optical lens is strongly recommended. Without a lens, you will see visible hot spots near the LED bars. With an asymmetric lens, uniformity ratios above 85% are achievable even in very shallow frames.
What voltage do your LED Light Bars with Optical Lens use?
All our optical lens LED light bars operate at DC24V constant voltage, compatible with standard 24V LED power supplies.
Are your optical lens LED modules ETL listed?
Yes. Our LED Light Bars with Optical Lens are ETL listed for the US and Canadian markets and CE certified for European markets.
Can I dim LED Light Bars with Optical Lens?
Yes. Our optical lens LED bars support 0–10V and PWM dimming, allowing brightness adjustment for different ambient lighting environments.
