Illuminance Recommendations: Lux and Footcandle Standards
When designing lighting for an ice hockey arena, understanding the difference between lumen, lux, and footcandle is essential. Lumens measure the total output of a light source, while lux measures the illuminance or the amount of light that falls on a given surface area. The lux value changes with distance, making it a critical measure for ensuring adequate lighting in an ice rink. In the United States, the lux requirement may also be expressed in footcandles (fc), where 1 fc equals 10.76 lux.
Horizontal Lux Requirement
Ice hockey rinks must meet specific horizontal illuminance values based on the level of competition. These values ensure that the entire rink is uniformly lit, allowing players to see the puck and each other clearly from all angles. The required lux levels vary depending on the type of event:
| Competition Level | Minimum Horizontal Lux | Equivalent Footcandles |
|---|---|---|
| Professional Championship Leagues | 1,200 lux | 111.5 fc |
| Smaller Leagues | 800 lux | 74.3 fc |
| Local and Regional Matches | 500 lux | 46.4 fc |
| Training and Recreational Use | 250 lux | 23 fc |
Vertical Lux Requirement
Vertical illuminance is also crucial, especially for ensuring that the rink is well-lit from different angles. The following are the vertical lux requirements for various levels of competition:
| Competition Level | Minimum Vertical Lux | Equivalent Footcandles |
|---|---|---|
| Professional Championship Leagues | 800 lux | 74.3 fc |
| Junior Championship Leagues | 500 lux | 46.4 fc |
| 2nd Division and Local Tournaments | 300 lux | 27.9 fc |
| Training | No specific requirement | No specific requirement |
Lighting Uniformity Requirement
Uniformity in lighting ensures that the entire ice rink is evenly lit, without dark spots or overly bright areas. Uniformity is assessed through two metrics: overall uniformity (Uo) and longitudinal uniformity (Ud). These values are calculated by comparing the maximum, minimum, and average lux readings across the rink.
| Competition Level | Horizontal Ud | Vertical Ud | Horizontal Uo | Vertical Uo |
|---|---|---|---|---|
| Professional Championship Leagues | 0.6 | 0.5 | 0.8 | 0.7 |
| Minor Championship Leagues | 0.5 | 0.4 | 0.7 | 0.6 |
| Junior Leagues | 0.4 | 0.2 | 0.7 | 0.4 |
| Training | 0.4 | Not required | 0.6 | Not required |
Color Temperature Regulations
The color temperature of the lighting affects how natural the lighting feels and is expressed in Kelvin (K). For ice hockey rinks, higher color temperatures are preferred to mimic daylight, which improves visibility and the overall experience.
| Competition Level | Color Temperature Range |
|---|---|
| Training and Low-Level Competitions | 3,000 K to 5,000 K |
| Junior Championship Leagues | 4,000 K to 6,000 K |
| Professional Championship Leagues | 5,000 K to 6,500 K |
Glare Control
Glare on the ice surface can be distracting and even dangerous for players. Glare control is managed using a GR-method or UGR-method, as outlined in standards like CIE publication 112-1994 and EN 12464-1. Properly shielded fixtures, the correct positioning of lights, and the use of glare shields or longer reflectors are all methods to reduce glare and ensure a clear view for players and spectators alike.
Color Rendering Index (CRI)
The CRI measures the ability of a light source to accurately render colors, which is particularly important for televised games. The following CRI values are recommended based on the level of competition:
| Competition Level | Minimum CRI Requirement |
|---|---|
| Professional Competitions | Over 80 Ra |
| Minor Competitions | 70 Ra |
| Training and Recreational Use | 60 Ra |
Lumen Maintenance Factor (LMF)
The LMF measures how well the lighting quality is maintained over time. Factors such as dust, dirt, and the quality of the installation can affect the LMF. Different light sources and fixtures have varying LMFs, and these should be considered when designing the lighting system.
| Fixture Type | LMF (IP 4X) | LMF (IP 5X) | LMF (IP 6X) |
|---|---|---|---|
| Light Sources ≤ 400 W | 0.60 | 0.65 | 0.70 |
Maintaining the LMF is crucial for ensuring long-term performance and avoiding deterioration in lighting quality. Proper maintenance and selection of fixtures with appropriate IP ratings help mitigate the impact of environmental factors on the lighting system.
