Lighting of parks and gardens should focus on the safety of pedestrians walking on the trails through the park. Lighting must allow pedestrians to discern obstacles or other hazard , and give them the opportunity to see other pedestrians. Waterproof light fixtures shall be used for such purpose.
Parks and gardens generally require white light in order to obtain a better color rendering. The white light provides improved visibility for pedestrians. Therefore, metal halide lamps with ceramic arc tube or the white LEDs are great options.
Recommended level of lighting for a park
Lighting in park areas shall meet recommended levels, and also minimize light pollution and intrusion on neighboring properties. The lighting level can significantly impact on the appearance and safety of the park at night. The high-pressure sodium lamps, a commonly used source for urban light, cast a yellow-orange light that gives poor color rendering; this light challenges the visual clarity and considerably impairs the overall quality of the night urban environment. In contrast, metal halide lamps diffuses a soft white light that makes colors more accurate; they provide better visual clarity, and require less power for the same perceived visibility. The light quality is also influenced by the amount of light – or more precisely, by the relationship between the brightness of light and the distance to the light source. The light becomes more diffused as we are farther from the source, so that for a given brightness, there are heights where we should place the light source to create the desired light quality.
Lighting fixtures for parks and gardens
The luminaires chosen for the lighting of parks and green spaces should be designed for outdoor lighting: waterproof light fixtures (at least IP 66), to maintain the initial performance as long as possible.
When the fixtures are installed at a relatively low height (up to 5m), vandalism should be taken into account. The lighting fixtures shall be built with strong material, such as aluminum body or polycarbonate for protection. Airfal Lighting offers attractive outdoor fixtures that maximize energy efficiency , with technologies such as LED.
Height of the luminary
The luminaire mounting heights generally increased over the past decades, which was made possible by more efficient lighting technologies. However, if one lowers the height of the light, the brightness of the lamp should be adjusted so that there is no excessive glare for pedestrians.
The aesthetic aspect must also be taken into account: the materials used, the shape and style of luminaries as well as the style should also integrate in the area.
Here is a lighting installation for the park Meandro Aranzadi in Pamplona, Spain. Airfal light fixtures were used for lighting the park.
Highlighting Techniques for parks and gardens
Path lighting is the most used technique of lighting a park or a garden. It results in a sense of safety along a walkway. It can be recommended to alternate the lights on either side of the path and place them slightly apart the path for greater visibility and ambiance.
Wall lighting is a technique where a light is placed on the ground and geared toward a building wall to create a soft, gentle light.
Down lighting highlights plants or other garden features from above. Down lights can be attached to garden walls or put in the tree, for instance by placing multiple in the trees.
With the uplighting technique, the objective is to place a light close to the base of an object, and to show off its form from below, and try to play around with the distance between the object and the light to create different angles of lighting.
