In modern China where ecological construction and green maintenance are the trend, the application of plants is becoming more and more extensive. Roads, courtyards, gardens, scenic spots, wetlands, mountains, etc. are everywhere. In the construction of plant landscapes, lighting is indispensable. A link. However, lighting design must not only protect plant ecology, but also meet functional lighting, and be full of artistic beauty. It is not an easy task. So what are the techniques that need to be paid attention to?
1. Lighting design method
The basic lighting methods of plants include top lighting and bottom lighting. In the specific design, more abundant lighting methods can be derived according to the types and positions of plants.
The lighting method is completely different from the plant lighting effect observed during the day. This lighting method can produce a dramatic effect.
The downlighting method can increase the natural expressive power of leaves and form certain special effects, such as the effect of moonlight lighting. But consider the size of the shadow on the ground or on the wall, and hide the light outlet of the light source as much as possible. This lighting method directly illuminates the front of the leaves, so the texture of the leaves will become more vivid and have a better color than during the day.
The lighting design should be based on the height of the plant, the overall texture and the characteristics of the branches and leaves, and the selection and control of the lamp position, light source and beam angle of the lamp should be carried out. Using mixed methods to illuminate plants can get a more dramatic effect and create the effect that the environment needs to form.
2, plant lighting source selection
Plant lighting needs to express its vibrant colors. Generally, white light or light sources similar to plant colors are used, mainly halogen lamps, metal halide lamps, and fluorescent lamps. Among them, metal halide lamps are suitable for medium or large-scale trees, and fluorescent lamps and halogen lamps are suitable for medium and small-scale trees, shrubs, and bushes.
The light color of the light source is particularly important in plant lighting. The same plant may have different color appearance and detail performance under different light sources, and it will give people a completely different feeling. The use of colored light to illuminate plants is also a more artistic lighting method.
White light can express the natural color of plants more naturally and meticulously, making people feel that plants are clear and clear, especially the white light of metal halide lighting can reflect the sense of hierarchy of plants.
Generally, the yellow light emitted by high-pressure sodium lamps can increase the warmth of the environment, but it is not suitable for illuminating green plants, because it will make the surface of green plants look gray and yellow, lacking vitality. For those who need to highlight the color feeling Yellow plants will have better results.
3. Selection and arrangement of lighting engineering lamps
The main consideration when choosing plant lighting fixtures is the light control ability of the fixtures, that is, the beam angle. Generally, the appropriate beam angle should be selected according to the height, density, shape, etc. of the plants to irradiate them.
According to the beam angle, the lamps can be divided into three types: wide beam, medium beam and narrow beam. Among them, the wide beam is suitable for lighting that needs to emphasize the shape of plants: for trees with dense foliage, use 40°-45° light control to illuminate, you can get an ideal lighting effect; on the contrary, when you need to illuminate a narrow one For tall trees, it is best to choose lamps with a beam angle of 6°-20°.
Underground lamps and projection lamps are often used in green lighting, which are prone to glare. Therefore, lamps with grilles or hoods are often chosen to reduce glare.
Special attention should be paid to the selection of the location of the lamps to ensure safety. The wiring should be hidden, and pedestrians, especially children, should not be directly exposed to the exposed electrical parts. In places where buried lamps are used, the temperature of the light outlet surface should not be too high to avoid scalding pedestrians. Try not to install the floodlight lamps directly on the tree poles. Overweight lamps will have an adverse effect on the growth of the trees, and the wires entangled on the tree trunks will not only cause leakage of electricity, but also hinder the view during the day.
