Secondary Focusing Lenses in LED Therapy Lights

Secondary Focusing Lenses in LED Therapy Lights - Which is Best?

In this article, we address some key factors regarding our LED lenses as well as those used in other LED therapy lights. 

Why is this important?

Effective treatment requires ensuring that our panels operate consistently, at the right wavelengths, at the right intensity, and provide full-body treatment. 

We want to maximize the surface area of the body's exposure to the light, as full-body treatment stimulates the mitochondria more effectively. 

When engineering LED therapy lights, another of our goals is to match the intensity at which the human body can absorb those respective wavelengths, and this actually varies.



Light Therapy Panel Bulbs: Expanding the Focus

Unlike a traditional incandescent light bulb that distributes light from all sides, most LEDs tend to focus light on special applications i.e. masks and wands, which are not ideal. 

In most cases, optimal treatment may come from full body exposure, so focused treatment does not always increase optical efficiency.  

LEDs seldom emit light evenly. The intensity is often far stronger in the middle than around the outside, and this is not ideal for consistent treatment.  


A Quality Solution

With over 12 years of experience designing and manufacturing high power LED panels for various applications, PlatinumLED was first manufacturer to utilize what are now known as 'secondary focusing lenses.' These solved the problem of uneven light distribution while maintaining the spread needed for full-body exposure. 

Now, in 2023, this technology has been widely adopted throughout the LED industry. However, this doesn't mean that most engineering teams have solved for correct light wavelength intensity.



Numerous products in the red light therapy industry are intended to focus light on specific body parts, which may not be a suitable approach for optimal treatment. 

Others have neglected to account for the specific needs of the body, by creating panels that emit wavelengths at arbitrary intensities, rather than at those in proportion to what the body can absorb for effective treatment. 

Furthermore, no competitor has managed to created mixed red and blue light treatment. The synergies of these wavelengths combined are part of what makes the BIOMAX series so powerful. 



Secondary Focusing Lenses for Optimal Light Distribution 

Let's take a closer look at our secondary lenses, what they do, and how they work.  

A secondary led focusing lens is a small piece of transparent acrylic that sits atop the LED to gather and re-emit light, much like a prism, at consistent intensities. The light is not magnified, but simply gathered and reflected.

Secondary lenses can also control the angle of the beam to determine the surface area of light exposure, simlar to a flashlight. This avoids creating a total internal reflection. 

The wider the angle of the beam, the greater the coverage but the less overall intensity due to the light being spread out. 

The tighter the angle of the beam, the less coverage but greater spot intensity due to the light being concentrated in one area, irrespective of the amount of light being emitted overall. 

Aside from the customized controls to modify timing and intensity, the lens aspect of the panels is factory-made for optimal lighting and intensity distribution.



Most RLT Panel Lenses on the Market

There is a significant variance in the light output of LED devices on the market, due to the emegence of new manufacturers.

The majority of LED therapy lights are built using cheaper parts with weaker lighting. This is often as much the case to save on production costs as it is the team's lack of experience and research into product development. High quality components also add to a manufacturer's costs. 



Additionally, equal consumption of wattage does not equate to equal treatment, because in many cases, the power may simply be getting converted into light that is emitted in suboptimal wavelenth proportions. 

To guage the wavelength of a panel, we recommend using a solar power meter, to measure the amount of light that would be exposed to the body. Take a look at a comparison of our panels to some market competitors to learn more about how they compare in terms of light output and intensity (page down to see the video). 

Since most LED therapy lights are underpowered, they compensate by using a tighter beam angle lens, typically of 30 or 60 degrees. While this may light increase intensity, it also decreases coverage. Instead of solving the intensity problem by downgrading the lense, we solved it by making LEDs that are more powerful. 



A Standardized 90 Degrees 

For the sake of precision coverage, we standardize lenses to 90 degrees.

Up until very recently, LED therapy lights were simply not available to the average user and thus, virtually all lights used a 30 or 60 degree lens to help boost their output. This is why many so many tests and studies have been conducted using lights that utilize these lenses. 

Thanks to the quality of internal components and its many years of LED manufacturing experience, PlatinumLED delivers a variety of ultra-high power, clinical level LED therapy light panels to the home user. These also include a small size, which is portable. 



Using RLT panels for home treatment has many advantages, including being lower cost and more efficient than seeking treatment in a clinical setting. 

Our panels are powerful to begin with, and we’re able to utilize wider 90 degree lens to deliver greater coverage while retaining superior light output.

Panels can also be mounted for easy use with a variety of stands

Take a look at our BIOMAX Series panels, the most advanced available on the consumer market. These are also the first panels to combine red and blue light treatment, for synergistic benefits.
