As a supplier of underground LEDs, I often encounter inquiries about the beam angle of these lighting products. Understanding the beam angle is crucial for both designers and end - users as it directly impacts the lighting effect and functionality. In this blog, I'll delve into what the beam angle of underground LEDs is, its significance, and how it affects different applications.
What is the Beam Angle?
The beam angle of an LED refers to the angle at which the light is dispersed from the source. It is measured in degrees and can range from very narrow to very wide. For underground LEDs, the beam angle determines how far and wide the light will spread on the surface above the fixture.
Imagine a flashlight. If you have a flashlight with a narrow beam angle, the light will be concentrated in a small area, creating a spotlight - like effect. On the other hand, a flashlight with a wide beam angle will illuminate a larger area, but the light may be less intense. The same principle applies to underground LEDs.
Types of Beam Angles in Underground LEDs
Narrow Beam Angles (10° - 30°)
Narrow beam angle underground LEDs are ideal for highlighting specific objects or areas. For example, in a garden setting, you might use a narrow - beam underground LED to spotlight a statue or a particular plant. The concentrated light draws attention to the focal point and creates a dramatic effect.
These LEDs are also useful in commercial settings, such as in museums or art galleries. They can be installed underground to illuminate display cases or art pieces, providing a precise and controlled lighting solution. The limited spread of light ensures that only the intended object is illuminated, reducing light spill and glare.
Medium Beam Angles (30° - 60°)
Medium beam angle underground LEDs strike a balance between highlighting and general illumination. They are suitable for lighting pathways, driveways, or small to medium - sized areas in a garden. The light spreads out enough to cover a reasonable area, while still maintaining a certain level of intensity.
In an Underground Lighting system for a residential property, medium - beam LEDs can be used to create a warm and inviting atmosphere. They provide enough light for safe navigation at night, without being overly bright or creating harsh shadows.
Wide Beam Angles (60° - 120°)
Wide beam angle underground LEDs are designed to provide broad illumination. They are commonly used in large open areas, such as parking lots, sports fields, or large gardens. The wide spread of light ensures that a large surface area is evenly lit, reducing the risk of dark spots.
In an Inground Pool LED Light application, wide - beam LEDs can be used to illuminate the entire pool area, creating a bright and safe environment for swimmers. The even distribution of light also enhances the aesthetic appeal of the pool, especially at night.
Factors Affecting the Choice of Beam Angle
Application
The intended application is the primary factor in determining the appropriate beam angle. As mentioned earlier, if you want to highlight a specific object, a narrow beam angle is the way to go. For general illumination of large areas, a wide beam angle is more suitable.
In a Underground Garden Lights installation, you may use a combination of different beam angles. Narrow - beam LEDs can be used to accentuate plants or sculptures, while wide - beam LEDs can provide overall illumination for the garden.
Installation Depth
The depth at which the underground LED is installed can also affect the choice of beam angle. If the LED is installed deeper underground, a wider beam angle may be required to ensure that the light reaches the surface effectively. Conversely, if the LED is installed closer to the surface, a narrower beam angle may be sufficient.
Surrounding Environment
The surrounding environment plays a role in determining the beam angle. In a densely vegetated area, a wider beam angle may be needed to penetrate through the foliage and provide adequate illumination. In an open area with few obstructions, a narrower beam angle can be used more effectively.
Importance of Beam Angle in Energy Efficiency
The beam angle of underground LEDs also has implications for energy efficiency. By choosing the right beam angle for a specific application, you can minimize light waste. For example, using a narrow - beam LED to illuminate a small area instead of a wide - beam LED will ensure that the light is concentrated where it is needed, reducing the amount of energy consumed.
In large - scale lighting projects, such as in commercial buildings or public spaces, proper beam angle selection can lead to significant energy savings over time. This not only benefits the environment but also reduces the operating costs for the end - user.
How to Select the Right Beam Angle for Your Project
When selecting the beam angle for your underground LED project, it's important to start by clearly defining the purpose of the lighting. Consider the area you want to illuminate, the objects you want to highlight, and the overall aesthetic you want to achieve.
If possible, create a mock - up or a lighting plan. This can help you visualize how different beam angles will affect the lighting in the space. You can also consult with a lighting designer or an expert in underground lighting to get professional advice.
