Garden landscape lighting design skills
The object of garden lighting is different from indoor lighting and architectural environment lighting, and its main purpose is to enhance the effect of scenery and create a night landscape. Therefore, in terms of the type of light source, the light source with better direction and control ability should be selected as far as possible, and the use of ordinary floodlighting lamps should be reduced.
Different locations of the garden have considerable differences in lighting requirements. In order to display the beautiful shapes of buildings, sculptures, flowers, trees, rocks and other objects in the garden, the lighting methods should be different from scene to scene, and the projected light should also be used according to needs. The intensity varies to show their own charm at night; the street lights on both sides of the garden road should have uniform and continuous illumination to meet the needs of safety.
In order to make a small space appear larger, only the necessary parts can be illuminated and the rest are placed in shadow; for large outdoor spaces, the treatment method is the opposite, which will create a sense of intimacy in the large space.
Dimmers on light sources should be used with caution for outdoor lighting. In most garden lamps that use incandescent lamps as the light source, the use of dimmers will make the light yellowish, and cast a layer of yellow on the irradiated objects, especially for plants, it will appear a morbid state and lose its original color. vitality.
Color filters or colored LEDs are also best used sparingly, because the light projected through them will create a sense of distortion, which will cause some kind of unrealism to plants. The exception, of course, is the sky blue filter, which removes the yellow tint found in incandescent lamps and turns the light into a pleasant blue-white. Small filters or other accessories can make a huge difference in the entire landscape, which needs constant attention in the design.
The brightness of the light should be determined according to the needs of the activity and to ensure safety. Too bright or too dark will bring discomfort to the tourists. The lighting design should pay special attention to glare. Hidden lamps among flowers and trees can provide the necessary lighting without causing glare.
To determine the lighting range of the light, the position of the lamp must also be considered, that is, the height, angle and light distribution of the lamp, and the size and brightness of the shadow formed during lighting must be coordinated with the environment and atmosphere, so as to facilitate the use of light and shadow to set off nature and create a certain scene and atmosphere. This should be carefully observed in the surrounding space during the day, and through calculation calibration to determine the best landscape lighting effect.
Here are some common scene lighting:
tree lighting
1. Flood lights are generally placed on the ground, and the arrangement is determined according to the type and appearance of the trees;
2. If you want to illuminate a higher position on the tree, you can place a metal pole with the same height as the lighting position next to the tree to install the lamp;
3. Install a series of low-power incandescent light bulbs or LED lamp beads on the main branches of deciduous trees to obtain decorative effects;
4. For the flood light that must be installed on the tree, the installation ring attached to the tree branch must be able to adjust according to the growth law of the plant;
5. The lighting of trees should pay attention to art.
Lighting of flower beds
1. For flower beds on the ground plane, the so-called magic valley lamps are used to illuminate downward. The lamps are often placed in the center or edge of the flower beds, and the height of the lamps depends on the height of the flowers;
2. The light sources are commonly used incandescent lamps, compact fluorescent lamps, metal halide lamps and LED light sources, and light sources with a relatively high color rendering index are used.
decorative lighting for statues
1. The number and arrangement of illumination points depends on the type of the illuminated target;
2. Determine the position of the lamp according to the position of the illuminated target and its surrounding environment:
a. For lighting targets isolated in the center of grass or open space, the lamps should be as flush with the ground as possible to maintain the surrounding appearance;
b. For the lighting target isolated in the center of the grass or open space, if it is located on the base, the lamps should be placed farther away to avoid shadows at the bottom of the illuminated target due to the occlusion of the base;
c. If the target is located on the base, if it is close to pedestrians, the lamps should be fixed on the public lighting pole or on the façade of the nearby building.
3. For statues, always illuminate the subject part of the face and the front of the statue. When choosing the irradiation direction, avoid shadows on the statue's face;
4. For some sculptures, the color of the light should be coordinated with the color of the sculpture material.
water feature lighting
1. Lighting of still water and lakes: the lamps illuminate the scene on the shore, which can form a reflection on the water surface; objects on the opposite bank can be illuminated by floodlights immersed in water; for dynamic water surfaces, floodlights can be used to directly illuminate the water surface ;
2. Illumination of the fountain: In the case of water jetting, install the floodlights behind the spout in the pool or below the drop point where the water falls back into the pool, or install lights in both places. The three primary colors of red, blue and yellow are often used, followed by green;
3. Lighting of waterfalls: For water flows and waterfalls, lamps should be installed at the bottom of where the water flows.
