Demystifying LED Light Beam Angles: A Comprehensive Guide

The LED light beam angle is a critical factor in shaping the ambiance and functionality of any space. It decides the spread of light from the lamp, determining everything from a narrow spotlight that highlights a piece of art to a wide floodlight that illuminates a basketball court.

But how exactly do these beam angles work, and how do we select the right angle for led light? Please follow me to know the LED Beam Angle Guide.

What is LED Light Angle?

The light angle refers to the range of light emitted from the LED light source. People obtain the light angle through measurement and optical design.

Simply speaking, the light angle refers to the size of the luminous range of the LED product after it is lit, that is, the beam angle.

The reflected light on the illuminated wall is a light source with the same spot size and light intensity. If used in reflectors with different angles, the larger the beam, the smaller the central light intensity, and the larger the spot.

For example, take the 15° angle beam diagram. From the picture, we can clearly see that the light in the center of the 15° angle beam is significantly brighter than the surroundings. The part of the light in the middle is called the central light intensity, and the entire light irradiation surface is called the spot.

As the beam angle increases, the intensity of the light in the middle weakens. If the angle reaches 120 degrees, the brightness of the light in the middle is almost the same as that of the surroundings, which is no different from the light effect of ordinary lamp beads.

Therefore, it is not difficult to draw the conclusion: the smaller the beam angle, the greater the light intensity at the center, the smaller the spot, and the better the light effect.

Choose The Right Beam Angle

The secret that determines the size of the beam angle is the lens angle. As long as a lens with a corresponding angle is added to the lamp bead, the beam angle can be locked.

Common beam angles currently on the market are 8°, 15°, 25°, 45°, 60°, 90°, and 120°.

According to the angle, they can be divided into: narrow-angle beam: <20°; medium beam 20°~40 °; wide beam>40°.  According to BEON’s professional light distributor, if you want to achieve better light effects, narrow-angle beam LED lights are the best choice.

1, Spot lighting:

  • For accent lighting or to highlight a specific object, choose a narrower beam angle (e.g. 10°-30°).
  • This creates a focused, dramatic effect.

2, General lighting:

  • Wider beam angles (e.g. 60°-120°) distribute light evenly.
  • Suitable for ambient lighting in your living room, kitchen or office.

3, outdoor lighting:

  • Floodlights are suitable for wide coverage (e.g. 120°).
  • Street lights use medium angles (e.g. 60°-90°).

Today here introduce to you some lenses used on the module. There are many types of lenses. Some of Beon lens angles include: 30 degrees, 60 degrees, and 90 degrees. . .

  • The surface of a lens with a lighting angle of 30 degrees is flat, not convex. When viewed from the opposite side, it is convex and grooved. Generally used on high pole lamps with long lighting angles.
  • The lens has a lighting angle of 60 degrees. It has a circular design and needs to be marked on its terminals. Generally used in tunnel lights.
  • A lens with a light angle of 90 degrees is slightly larger than a circular lens with a 60 degree angle. Generally used in floodlights.

The above three models all have small angles, and the usage scenarios all require focusing light, so the angle we choose should be smaller.

Whether you’re creating a cozy nook for a specific area or lighting up a vast space, choosing the right beam angle ensures your lighting vision becomes a reality.



What Are The Most Common Beam Angles Used In Street Lighting?

Choosing the correct street light beam angle requires consideration of pole height, road width and lighting needs.

The beam angle determines the distribution range of the light. Different beam angles are suitable for different lighting needs. For example:

Narrow-angle beam (smaller angle): suitable for narrow roads or areas that require concentrated lighting.

Wide-angle beam (larger angle): suitable for wide roads or areas that require even lighting.

Street lights typically emit light at an angle of 70° x 140°. This led angle is cleverly designed to ensure a wide illumination range in the horizontal direction (70°), while a narrow illumination range in the vertical direction (140°). This effectively illuminates the road, reduces light pollution, and improves energy efficiency.

What Are The Most Common Led Angles Used In Sport Lighting?

The led angle of sports lighting usually varies according to different venues and needs. The following are some common sports lighting angles and some specific cases:

  • Narrow angle beam (5° – 18°):
    Ideal for areas that require precise lighting, such as a goal on a football field or a hoop on a basketball court.
    Case: In football matches, narrow-angle beams are used to illuminate the goal area to ensure that players and goalkeepers can clearly see the goal.
  • Narrow angle beam (18° – 30°):
    Suitable for large sports venues that require centralized lighting, such as track and field or football fields.
    Case: In track and field competitions, narrow-angle beams are used to illuminate the track and long jump area to ensure that athletes can see the competition line clearly.
  • Narrow flood beam (30° – 60°):
    Ideal for sports venues covering larger areas, such as tennis courts or swimming pools.
    Case: In a tennis match, a narrow flood beam is used to illuminate the entire court to ensure that both players and spectators can see the match.
  • Flood beam (60° – 90°):
    Ideal for indoor and outdoor venues that require uniform lighting, such as basketball or volleyball courts.
    Case: In a basketball game, flood beams are used to ensure that the entire court is adequately illuminated without shadows or blind spots.

The LED angle of sports lighting should be selected according to the specific sports, venue size and lighting needs to ensure the fairness of the game and the visual experience of the audience.
