When comparing red light panels, most people focus on things that are easy to understand. Number of LEDs, power, treatment area and price tend to get the most attention. At the same time, there are several technical details that are of great importance for how the panel actually works in practice.
One of these details is the LED lens.
If you have read the specifications for a modern red light panel, you may have seen terms like Convex LED lens or Convex PRO lens. For many customers, this doesn’t mean much. However, for manufacturers and product developers, it is an important part of how the light is spread from the panel.
What is a Convex LED Lens?
The word "convex" means that the lens is curved outwards.
The lens is placed in front of the LED and helps control how the light is spread. Without a lens, the light would be spread differently and the panel would have different properties.
The lens works much like the reflector in a flashlight or headlamp. It helps direct the light where it's supposed to go instead of letting it spread out uncontrollably.
That's why the lens is an important part of the panel's construction, even though it often receives very little attention.
Why are lenses used in red light panels?
The goal of a red light panel is not just to produce light but to deliver the light in a controlled manner.
By using lenses, the manufacturer can influence:
| Function | Effect |
|---|---|
| Light scattering | How large an area is covered? |
| Light intensity | How much light reaches the treatment area |
| Evenness | How evenly the light is distributed |
| User experience | How the panel works in practice |
The lens is therefore an important piece of the puzzle when creating a high-performance panel.
What does 60 degree beam angle mean?
Many red light panels also indicate a beam angle, for example 60 degrees.
The spread angle describes how the light leaves the panel and how widely it is distributed in front of the product.
A wider spread typically covers a larger area while a narrower spread concentrates more of the light into a smaller area.
That's one of the reasons why the lens design plays an important role in the panel's properties.
Can two panels with the same LED lights work differently?
Yes.
It's actually quite common.
Two panels can use the same wavelengths and similar LED components but still provide different user experiences depending on how the lenses are designed.
This is also why serious manufacturers place great importance on the optics and do not just focus on the LED lights.
Light must not only be produced, it must also be distributed efficiently.
The convex lens is part of the whole
Just like irradiance, Dual Chip LED technology and Mean Well drivers, the lens is part of a larger whole.
No single component alone determines how good a red light panel is. It is the combination of components that determines the final performance.
Therefore, it is important to see the entire product design instead of getting stuck on a single specification.
How does Infracenter work with lens construction?
In the PRO MAX series, Infracenter uses Convex PRO lenses with a 60 degree beam angle. The goal is to create an effective balance between light intensity, treatment area and ease of use.
Together with quality components such as Mean Well drivers and Dual Chip LED technology, the lens design contributes to creating the whole that characterizes the PRO MAX series.
We believe that it is the interaction between all components that creates a truly great product.
Summary
A Convex LED lens is a curved lens that is placed in front of the LED lamp to control how the light is spread.
Although the lens is a small detail, it has a major impact on how the panel works in practice. It affects, among other things, light spread, light intensity and how evenly the light is distributed across the treatment area.
As with other technical specifications, it is not a single component that determines the quality of a red light panel. It is how all the parts work together that creates the final result.
