In the construction of plant phenomena, lighting is an indispensable link. However, lighting planning must not only maintain plant ecology, but also satisfy functional lighting, and be full of artistic beauty, which is not a simple task. So what are the techniques that you need to pay attention to?
1. Lighting planning method
The basic lighting methods of plants include top and bottom lighting. In specific planning, more abundant lighting methods can be derived according to the type and orientation of plants.
The lighting method is completely different from the light effect of plants observed during the day. This lighting method can have a dramatic effect.
The downward lighting method can increase the natural expressive power of the leaves and constitute a certain special effect. This lighting method is to directly illuminate the front of the leaves, so the texture of the leaves will become more vivid and have a better color than the day.
2. Selection of plant lighting sources
Plant lighting needs to show its vibrant color. Generally, white light or a light source similar to plant color is used, mainly halogen lamps, metal halide lamps, and fluorescent lamps.
Among them, metal halide lamps are suitable for medium or large standard trees, while fluorescent lamps and halogen lamps are suitable for medium and small standard trees, shrubs, and bushes.
White light can express the natural color of plants in a more natural and detailed manner, and make people feel that plants are clear and clear. In particular, the white light of metal halide lighting can express the sense of hierarchy of plants.
3. Selection and settlement of lighting engineering lamps
The primary consideration for selecting plant lighting fixtures is the light control ability of the fixture, that is, the beam angle. Generally, the appropriate beam angle should be selected according to the unevenness, density, and shape of the plants to illuminate them.
According to the beam angle, the lamps can be divided into three types: wide beam, medium beam, and narrow beam. In the meantime, the wide beam is suitable for lighting that needs to focus on the shape of plants: For trees with lush foliage, use 40°-45° light control to illuminate, you can get a more interesting 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°.
Special attention should be paid to the selection of the orientation 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, care should be taken that the temperature of the light outlet should not be too high to prevent pedestrians from being burned.
