Trees

Types of illumination

Floodlights aimed upwards make the tree crown appear three-dimensional. Two floodlights from the front, yet to the side, illuminate the crown evenly as a voluminous mass, while floodlights mounted at the side add greater emphasis to the three-dimensionality. Floodlights arranged around three sides illuminate the crown evenly from all sides and reduce the three-dimensionality of the tree form. Floodlights in the background create back-lighting and make the tree crown into a silhouette Uplights at the trunk accentuate the trunk as a linear feature and visually connect the crown to the ground. Depending on the season, light from above will either emphasise the contour of the crown or accentuate the shadows of the branch structure on the ground.

Luminaires arranged on several sides give an even illumination of the tree, while one or two luminaires create a greater three-dimensional effect. Narrow-beamed uplights are suitable for highlighting any striking, tall tree trunks. The texture of the bark is brought out stronger when lighting from the front. Positioning the luminaires to the side gives rise to a narrow line of light on the trunk. When illuminating a wall behind a tree, the silhouette of the crown and trunk becomes apparent. Spotlights mounted in atria or on facades can cast the contour of the tree and/or branches as a shadow on the ground.
