When it comes to red light therapy devices, we often encounter terms such as power, wavelengths, and dose. However, another crucial factor that is often overlooked is the lens beam angle. This can significantly influence how the light affects your skin or deeper tissue. In this post, we explain what the beam angle is, how it affects your therapy, and how to choose the right beam angle for your needs.

What is the beam angle?

The beam angle describes how wide or focused the light from an LED device is emitted. It is the angle within which the light is effectively emitted before gradually losing intensity.

📌 A wider beam angle (e.g., 60° or more) means the light is scattered further, covering a larger area but with less intensity.
📌 A narrow beam angle (e.g., 30° or less) concentrates the light more intensely on a smaller area, increasing intensity and allowing for deeper penetration.

How does the beam angle affect your therapy?

The beam angle plays a crucial role in red light therapy applications and can influence both superficial and deeper tissue treatments.

• Wide Beam Angle (e.g., 60° or more):

  • Covers a larger area simultaneously.

  • Ideal for large-area treatments such as skin rejuvenation or muscle recovery.

  • Provides a more even light distribution, but with lower intensity.

  • Especially useful when the goal is area-wide, gentle therapy.

• Narrow Beam Angle (e.g., 30° or less):

  • Concentrates light on a smaller area.

  • Ideal for targeted treatments, especially for deep tissues like muscles, joints, or organs.

  • Higher intensity, leading to deeper light penetration.

  • Especially useful when targeted, intensive therapy is desired.

How to choose the right beam angle?

Choosing the right beam angle depends on your specific goals and the desired depth of application.

1. Superficial Skin Treatments (anti-aging, skin repair):

   • A wider beam angle of 60° or more is ideal, as even light distribution over a larger area is desired.

2. Deeper Tissue Treatments (muscles, joints, organs):

   • A narrower beam angle of 30° or less is more suitable for delivering more intense light deeper into the tissue.

3. Combined Therapy:

   • If you want to treat both superficial and deeper tissue layers, a device with variable lenses or a combination of 30° and 60° beam angles is optimal.

heilys Panels: Optimal Combination of 60° and 30° Beam Angles

Our heilys panels specifically utilize two different beam angles to optimally treat both superficial and deeper tissues:

• Red Light (630nm, 660nm, 670nm): With a 60° beam angle, it achieves widespread applications evenly and effectively. This is ideal for applications such as skin rejuvenation, skin healing, and collagen production, where gentle, even irradiation is desired.

• Infrared Light (810nm, 830nm, 850nm): With a 30° beam angle, the light is projected more focused onto deeper tissues, leading to higher intensity and deeper penetration. This is particularly effective in treating muscles, joints, and organs.

This combination allows for precise control of the therapy, covering both broad and focused areas. This maximizes biological effects and offers versatile application possibilities for different needs.

Conclusion: Wide vs. Narrow – Which Beam Angle is Right?

• For large-area applications such as skin rejuvenation or muscle recovery, a wide beam angle is ideal.

• For targeted applications on deeper tissue, a narrow beam angle is more suitable.

• The combination, as seen in heilys Panels, offers the perfect balance between area-wide and focused light therapy.

With this well-thought-out design solution, heilys enables optimal application for a variety of therapy goals.
