7. Our LEDs – the heart of our Luminousred machine

Today’s article will focus on our LEDs. Where do they originate, what are their benefits, how do they compare to lasers or light bulbs, and what are our unique new features?

In 1962 Nick Holonyak Jr. developed the first light-emitting diode (LED). It was a red LED. LED Lights have numerous advantages compared to lasers or light bulbs. Their life span and energy efficiency are much longer, we calculated this a while ago, and with our LEDs, you can count with over 50.000 hours, that’s more than five years if you run them 24/7, how about that! Also, they don’t radiate any heat while being more intense and direct. LEDs are a recent application method. The main difference is that they allow the light to shine onto a broader surface area. Research has been mainly using lasers, but the interest is arising in using LEDs too. LEDs have been extensively used in the beauty industry and elite sports for a long time now because they are a cost-effective way to deliver beneficial light effects. At-home devices use LEDs most of the time as it is a safe, effective, and secure way to give effects. In contrast to an incandescent light bulb, LEDs have a specific pattern in which they emit light. While a light bulb emits light from all sides of the bulb, LEDs emit light in a more focused pattern.
Lasers are also known as low-level-laser therapy (LLLT) or cold lasers and are used widely in research scenarios and the scientific application of Photobiomodulation. They provide the deepest penetration to a single point. Generally, they are administered by a trained technician or medical/health professional. To sum up the user case of low-level-lasers: they can be expensive, treat a limited area, often require going to a clinic so not as handy for at-home use.

Now to our unique Luminousred features

Our LEDs are dual LEDs.
As most of you know, we’ve recently stopped the production and selling of our devices. It was precisely at this time we decided to come back stronger and build in all the features we were only dreaming about before. With dual LEDs, no matter if you use all wavelengths or just one, you will get a uniform area of light on your body. Why is this so special? Uniformity has been one of the significant obstacles in the field so far. One problem with how the light is emitted from LEDs is that it’s not emitted evenly over an area.  The emission of light is much more concentrated in the middle than the sides of the circle. Only when you’re uniformly lighting the body area you want to tackle; you can get the maximum amount of light absorbed by your body. ⁠
Also, when using only one wavelength (for example, only red light at 660nm for skin issues or near-infrared light at 850nm for deep tissue penetration), the light intensity is now higher. These are essential user cases, as both wavelengths switched on mostly serve for general wellness and well-being. If you want to dig deep on various benefits, you should know how to dose which wavelength precisely. Before, when using one wavelength, only half of the LEDs were in action. Now, all the time, ALL LEDs are in operation. We’ve mentioned this a couple of times: the premise of all red-light therapy applications is that the more light you can shine onto an area of skin, the better. See our dosing article for more information. We’ve made use of this now with our dual LEDs.

30-degree beam angle.
Beam angle matters because coverage is an essential aspect of what makes a useful red-light therapy device, the more coverage, the better. A beam angle too broad means the LED loses intensity and, therefore, its benefit. If the beam angle is too narrow, you’re most likely not getting enough coverage and need to have a greater distance to your device. With a controlled beam angle, we can emit the light in an even and tighter manner and help focus it precisely onto the area it is supposed to be at your body. With a lot of other devices out there, you have the light kind of all over the room, which is a tremendous atmospheric scenario but not an efficient treatment setting. Most studies have been focussing on lasers and beam angles that were 30 degrees and below. The LEDs in our devices come equipped with a 30-degree beam angle to ensure you’re getting the right intensity and coverage at the same time.
