Application of LED track lighting

LED track lighting refers to light fixtures that use LED light sources and are installed on tracks. With their flexible, efficient, energy-saving, and environmentally friendly features, they are widely used in various commercial spaces. LED track lighting has the advantages of improving lighting quality, saving energy costs, reducing maintenance costs, and creating safer, more comfortable, and aesthetically pleasing environments for people.

LED track lighting is often used in commercial and office spaces. For example, using LED track spotlights in supermarkets, shopping malls, and retail stores can provide focused lighting for displays. Using LED track panel or linear lights in offices and conference rooms can provide uniform, high color rendering, and energy-efficient lighting effects.

LED track spotlights are also ideal for cultural scenes such as museums, galleries, and exhibition spaces, as they can provide high-quality exhibition lighting while protecting exhibits from light damage.

What is the beam angle of LED track lighting?

The beam angle, also called “beam spread,” refers to any light that falls within the 50% range of maximum intensity generated by the light bulb, and is usually expressed in degrees. It describes an important parameter for the size and brightness distribution of the illumination range of a light source at a given distance. The smaller the beam angle, the more concentrated the scattered light, the smaller the illumination range, and the higher the brightness; the larger the beam angle, the more dispersed the scattered light, the larger the illumination range, and the lower the brightness.

NEMA Beam Classifications?

NEMA classifies the beam angle of light fixtures into seven categories, from very narrow spotlights to very wide floodlights, which helps us choose the appropriate beam angle fixtures for lighting design.

Beam Angle NEMA Classification Name

10°-18° Ⅰ Very Narraw

18°-29° Ⅱ Narrow

29°-46° Ⅲ Medium-Narrow

46°-70° Ⅳ Medium

70°-100° Ⅴ Medium -wide

100°-130° Ⅵ Wide

130°+ Ⅶ Very wide

Very Narraw, Narrow: Typically used for localized lighting and emphasizing object details.

Medium-Narrow, Medium: Typically used for moderate lighting range and uniform lighting effects.

Medium-wide, Wide: Typically used for wide lighting range and soft lighting effects.

The importance of choosing the appropriate beam angle

Choosing the appropriate beam angle is crucial for the performance and effectiveness of LED lighting systems. It improves the lighting quality of commercial spaces, facilitates energy-saving, and creates a comfortable environmental space.

Improving lighting quality

Different lighting requirements call for different beam angles. For instance, in areas requiring focused lighting, a narrow beam angle is needed to obtain high brightness and clear lighting effects. In contrast, for areas requiring broad coverage, a wide beam angle is necessary to obtain uniform lighting effects.

Enhancing energy-saving effects

Choosing the appropriate beam angle can reduce energy waste. For example, selecting a beam angle that is too wide may result in over-illumination and energy waste. Conversely, if a beam angle is too narrow, more light fixtures may be required to achieve the desired lighting effects, which would also waste energy.

Creating comfort

Choosing the appropriate beam angle can also improve user comfort. Excessive lighting effects may cause glare and visual fatigue, while insufficient lighting may affect work and learning efficiency.

The relationship between beam angle and lighting effects

When planning lighting for commercial spaces, selecting the appropriate beam angle can improve the brightness, uniformity, and comfort of lighting. Here are some examples of the relationship between beam angle and lighting effects:

Beam angle and illumination range

A larger beam angle results in a wider illumination range, while a smaller beam angle results in a smaller range. Selecting the appropriate beam angle can make the light fixture’s coverage more accurate and achieve the best lighting effects.

Beam angle and illumination intensity

A smaller beam angle results in higher illumination intensity, making narrow beams suitable for emphasizing and highlighting objects. A larger beam angle results in lower illumination intensity, making broad beams suitable for soft lighting effects.

Beam angle and uniformity

The appropriate beam angle can improve lighting uniformity, ensuring even illumination. For example, medium beam angles are suitable for medium-sized spaces that require uniform lighting.

Creating comfort

Excessive lighting effects may cause glare and visual fatigue, while insufficient lighting may affect work and learning efficiency. Choosing the appropriate beam angle can improve user comfort and allow the light fixture’s shade angle to fall within a suitable range, which also helps control glare.

Energy-saving effects

Selecting the appropriate beam angle can reduce energy waste. Choosing a beam angle that is too wide may result in over-illumination and energy waste, while choosing a beam angle that is too narrow may require more light fixtures to achieve the desired lighting effects, which would also waste energy.

Characteristics and Application Scenarios of Different Beam Angles

Different lighting effects require different beam angles to achieve. Typically, narrow beam angles are used for accent lighting, medium beam angles are used for display lighting, and wide beam angles are used for ambient lighting. Here are the characteristics and application scenarios of different beam angles:

Narrow beam angles (10°-30°): Light within this range can be concentrated in a small area, forming obvious brightness and contrast. Therefore, it is mainly used in situations where a specific area or object needs to be emphasized or highlighted, such as in retail store counters, gallery displays, hotel lobbies, etc.

Medium beam angles (30°-60°): Medium beam angles have a wider scattering range and can provide relatively uniform lighting effects. They are usually used to cover medium-sized areas, such as model lighting in retail stores, wall washing lighting, and shelf lighting in supermarkets. These areas do not require obvious brightness and contrast, but do require specific areas to be highlighted.

Wide beam angles (greater than 60°): Wide beam angles have a very wide scattering range and can spread light to a wider area. They are usually used to provide soft basic lighting for a space, such as in the entrance area of a supermarket, the lobby area of an office, or an open office area.

What is the Beam Angle of LED Track Lights?

LED track lighting has a variety of lamp types, and we will share the beam angle range of two commonly used LED track lighting: track panel lights and track spotlights.

Beam Angle of LED Track Panel Lights

LED track panel lights are usually used to provide uniform lighting, and the beam angle range is usually between 61°-120°, but this can vary depending on the scene and the type of lamp.

Display Area

The display area is a very important area in the supermarket, and the lighting effect in the display area directly affects the attractiveness and sales volume of the goods. LED track spotlights are usually used to provide display lighting for products, highlighting the features of the products and improving the lighting effect.

For areas with low shelf height and high luminaire installation height, a medium beam angle, such as 24° or 36°, can be selected to concentrate the light on the goods on the shelves and improve the lighting effect.

For areas with high shelf height, such as higher than 2.5 meters, a wider beam angle, such as 55°, can be selected to distribute the light evenly on the shelves, avoiding strong shadows and uneven lighting.

The display area also has some shelves for flat-displayed goods. In this case, we need to consider not only the height of the shelves but also the width. For narrower shelves, selecting a medium beam angle of 24° or 36° can better concentrate the light on the goods, while for wider shelves, a wider beam angle of 55° is needed to ensure sufficient lighting for the entire shelf and to have a suitable light ratio with the corridor area.

Promotion Area

The promotion area is usually the key promotion area of the supermarket, and it needs to use brighter lighting effects to highlight the displayed goods, to attract the attention of customers, and to increase the transaction rate of promotional area products.

In this area, a narrow beam angle of 24° or 36° is the best choice, as the narrow beam angle can add strong contrast to the goods and make the light brighter, making the goods stand out more in the entire supermarket space.

Checkout Area

The checkout area is the critical area of the supermarket transaction, and it requires adequate lighting so that staff can clearly confirm the goods and receipts, etc. The checkout area usually requires bright and uniform lighting while considering glare and uniformity to protect the staff’s vision and customers’ shopping experience.

To achieve these lighting effects, we can use LED track spotlights with a medium beam angle (36° or 55°). When considering the beam angle, we need to consider the installation height and the lighting angle of the luminaire to determine the specific value more accurately.

How to choose the beam angle of LED track lights in restaurant lighting

In restaurant lighting, LED track spotlights are commonly used for ambient or accent lighting, such as using track lighting to highlight feature walls or decorative items.

Feature walls

Restaurants need to provide a comfortable and warm lighting environment to enhance the dining experience of customers. LED track lighting fixtures are typically used for decorative lighting to add more layers to the restaurant.

This type of lighting typically uses a wide beam angle of 55°, which is conducive to providing even and soft wall washing lighting for the wall, creating a warm and comfortable atmosphere in the restaurant space, while also avoiding the wall looking too prominent.

Bar area

The bar area is an important area in the restaurant and requires prominent and moderately bright lighting to highlight the features and atmosphere of the bar. The use of LED track spotlights can illuminate the bar area more precisely, and through different combinations of lighting fixtures, create different atmospheres and styles.

When using track lighting in the bar area, the beam angle of the lighting fixture can be determined according to the atmosphere of the restaurant. Typically, a smaller beam angle (15° or 24°) can provide an artistic atmosphere with light and dark contrast for the bar, while a wider beam angle (55°) can provide more even illumination for the bar.

Entrance area

The entrance area is an important area of the restaurant facade and usually requires LED track lighting fixtures to illuminate the entrance. Lighting fixtures with a medium beam angle (24°-36°) are typically used to highlight the effect of the entrance photo or store logo, providing sufficient brightness and vivid color lighting effects, while also creating a unique storefront image and atmosphere through different combinations of lighting fixtures.

How to choose the beam angle of LED track lights in office lighting?

When selecting the beam angle of LED track lights for office lighting, it is important to choose the appropriate beam angle based on the specific functions of the office space. For example, meeting rooms and reception areas may require softer and more diffuse lighting, which can be achieved using wide beam angle fixtures such as track panel lights with a beam angle of 120 degrees. For the office area, track panel lights with a beam angle of 60°-80° can be used to achieve a concentrated downward light and good glare control.

Exhibit lighting: To showcase artwork and exhibits, a small beam angle (usually between 10° to 30°) is needed to achieve focused and precise lighting, highlighting the details and texture of the exhibits while minimizing interference with other areas.

Space lighting: In addition to exhibit lighting, the lighting of the entire space should be soft and comfortable to create a pleasant exhibition environment. In this case, a larger beam angle (such as 45° to 60°) LED track lighting can be chosen to achieve broader and more even lighting.

Installation height: The installation height of LED track lights will affect the choice of beam angle. Higher-ceiling museums may require smaller beam angle LED track spotlights to ensure the light accurately illuminates the artwork. Lower installation heights may need even smaller beam angles to avoid illuminating more unrelated areas.

Distance between fixtures: Proper spacing between fixtures can ensure that the light in galleries and museums does not intersect, making the entire space’s light spots clean, flat, and orderly. Adjust the distance between fixtures according to the beam angle and installation height to achieve the best lighting effect.

What is the optimum beam angle for an LED light?

The best beam angle for LED lights depends on the application. Different applications have different requirements for beam angle. For example, when LED lights are used for key lighting (such as lighting artwork or display cabinets), a beam angle of 24° or 36° is usually the best choice for normal installation height. When used for general home or office lighting, a larger beam angle can provide a soft and even lighting effect. These lights are typically used for basic lighting and have a beam angle of 80°-120°.

What is an adjustable beam angle luminaire?

An adjustable beam angle luminaire is a type of track spotlight designed to adapt to various lighting environments. Its main feature is the ability to adjust the beam angle according to the desired lighting effect. This flexibility in lighting design can meet a variety of needs, such as accent lighting, spotlighting, and wide-angle illumination. Adjustable angle luminaires are often used in spaces where room layouts or illuminated objects change frequently, such as galleries and exhibition halls.

Adjustable beam angles typically come in a range, with different models from different brands offering various adjustment ranges.
