DIY Red Light Therapy Panels: A Complete Guide on Building Your Own Near-Infrared Device

Introduction to DIY Red Light Therapy

Red light therapy, also known as photobiomodulation or low level light therapy (LLLT), is a trending skin and health treatment that utilizes red and near-infrared light to stimulate cellular functions and promote healing, repair and rejuvenation. While professional red light therapy devices can be quite expensive, there has been a growing interest in DIY red light therapy panels as a more affordable option to experience the purported benefits of red and near-infrared light.

The basic premise behind red light therapy is that specific wavelengths of red and near-infrared light interact with cytochrome c oxidase in the mitochondria of cells, helping cells to produce more ATP (adenosine triphosphate, the energy molecule of cells). This can lead to benefits such as reduced inflammation and pain, faster healing of wounds and injuries, enhanced tissue repair and increased collagen and elastin production.

A DIY red light therapy panel allows you to experience these benefits from the comfort of your own home. However, it is important to educate yourself on the parameters of an effective DIY red light therapy device and safely assemble such a panel.

Choosing the Right LEDs

The key component of any DIY red light panel are the LED lights. You want LEDs that emit light in the wavelength range of 600-950nm, which includes the visible red spectrum and near-infrared spectrum.

Some of the most common LED wavelengths used in DIY red light panels include:

• 660nm (visible red)
• 850nm (near-infrared)
• 940nm (near-infrared)

For a more complete red light therapy experience, choose an assortment of LEDs within this therapeutic wavelength range. An evenly balanced mix of visible red light LEDs (660nm) and near-infrared LEDs (850nm and 940nm) is recommended.

Power and Intensity

You want LED diodes that are powerful enough to deliver an effective dose of red/near-infrared light. Generally, LEDs with a power rating of 100mW (100 milliwatts) or higher are used. The LEDs should also have a narrow viewing angle (30-60 degrees) to concentrate the light intensity.

LED Density

Higher LED density will allow for broader coverage of red/near-infrared light. Aim for at least 40-50 LED diodes per square foot. The LEDs should be spaced evenly to achieve uniform light distribution.

Heat Management

Some heat is generated from the LEDs and managing thermal buildup is important for safety and LED longevity. Using LEDs with built-in heatsinks helps dissipate heat. Spacing the LEDs evenly will also prevent overheating.

Safety Standards

Purchase LED diodes certified under safety standards such as FCC, CE and RoHS compliance for electrical safety and lack of toxic materials.

Constructing the DIY Red Light Panel

Once you have acquired the necessary LED lights, constructing the actual red light panel will require some craftsmanship and electrical skills.

Wiring

Soldering wires between the LED diodes and connecting wires to a power source in parallel circuitry enables all the LEDs to turn on simultaneously when powered.

Power Source

You will need a power source, such as a DC power adapter, that can handle the wattage needs of all the LEDs wired together. Ensure your power source matches the voltage requirements of the LEDs (typically 12V DC).

Back Panel

Mounting the wired LED diodes onto a back panel provides structure and housing to the light. Use a rigid material like wood, acrylic or metal. Space and layout the LEDs evenly based on your density goals.

Front Cover

The front cover should be made of a transparent or translucent material that allows the red/NIR light to pass through and diffuse over a broader area while still protecting the LEDs. Acrylic sheets or polycarbonate plastic are good options.

Frame

Constructing a stable and protective frame to encase the back panel and front cover is optimal. This can be done with materials like wood, PVC pipes or metal framing.

Stand/Hanging Apparatus

You may want to fashion a stand or hanging system to position your DIY red light panel above you hands-free while in use.

Using Your DIY Red Light Therapy Panel Safely

Once assembled, using your homemade red light therapy panel requires some safety considerations:

• Do not stare directly into the red/NIR LED lights
• Start with short 5-10 minute sessions and gradually increase to 15-20 minutes max as tolerated
• Keep 12-18 inches distance between the light panel and your body
• Never fall asleep while undergoing red light therapy due to the heat generation
• Check for overheating of the LEDs and panel periodically
• Cover any photosensitive medications on your skin
• Consider eye protection especially for near-infrared wavelengths

It is generally advised to consult your doctor before starting red light therapy if you have any medical conditions or are on photosensitive medications.

Potential Benefits of DIY Red Light Therapy

Research indicates red light therapy offers a range of health and cosmetic benefits. While outcomes can vary based on treatment parameters and individual physiology, potential benefits of DIY red light therapy include:

• Wrinkle reduction & anti-aging: Boosts collagen production to improve skin elasticity and reduce fine lines/wrinkles.
• Skin rejuvenation: Improves tone, texture, hydration for an overall glowing complexion.
• Healing wounds & scars: Supports faster healing of cuts, burns, abrasions and post-surgical wounds.
• Acne treatment: Reduces inflammation and bacteria to improve acne.
• Pain relief & tissue repair: Reduces muscle aches & joint pains while speeding up sprain/strain recovery.
• Hair growth: Energizes follicles and increases circulation to stimulate growth.
• Improved circulation: Expands blood vessels to increase blood flow and oxygenation.
• Immune function: May enhance immunity by energizing T-cells and modulating inflammation.

The unique benefit of DIY red light therapy is being able to leverage these therapeutic effects in your own home with an affordable, customizable treatment panel.

Bottom Line on DIY Red Light Therapy

Constructing your own red light therapy device allows you to reap the growing benefits of red and near-infrared light for skin health, healing, pain relief and more—on your own terms and budget. With the right LED diodes and constructive plan, you can enjoy an at-home spa-like experience safely. Be sure to educate yourself on the parameters of an optimal DIY near-infrared red light therapy panel. Your individual health goals and skin type will also determine the best panel setup and treatment regimen.

While professional device options with precise wavelength specifications do offer advantages, the DIY approach can achieve many of the core benefits more affordably. Done correctly, investing some time into a homemade red light therapy panel can yield satisfying wellness and cosmetic results.
