Building lighting can be seen everywhere, and it has become an indispensable landscape in the city. How are these beautiful and brilliant lighting projects realized? The editor summarizes the following based on years of experience in the lighting engineering industry:
1. The attributes of the building itself
The lighting of the building body may produce different lighting effects due to its different appearance, or a more uniform feeling, or a feeling of strong light and dark changes; it can be a more flat expression, or a more lively The way of expression depends on the attributes of the building itself.
2, the choice of lighting engineering light source
The choice of light source should consider factors such as light color, color rendering, efficiency, and life span. The light color is quite related to the color of the exterior wall materials of the building. Generally speaking, bricks and yellowish-brown stone are more suitable for irradiating with warm light. The light source is high pressure sodium lamp or halogen lamp.
3. Illumination value of building body lighting
Because of the surrounding environment of the building and the different exterior wall materials, the illuminance value required to meet the lighting effect will also be different, and the illuminance value is for the main facade. Generally speaking, the illuminance of the secondary façade is half of the main façade, and the three-dimensional sense of the building can be expressed by the difference in brightness of the two sides.
4. Lamps and lanterns used in the lighting project
The lighting angle and light uniformity of lamps of different shapes are different. The angle of the square projecting light is larger, and the angle of round lamps is smaller. Wide-angle lamps have a more uniform effect, but are not suitable for long-distance projection; narrow-angle lamps are suitable for long-distance projection, but have poor uniformity when used at close distances.
5. Illumination and calculation of the number of lamps
Determine the number of lamps and lanterns according to the illuminance calculation of the selected light source, lamps, installation location and other conditions, so that the effect can be as close as possible after the installation is completed. The appearance of the building is expressed by the projection of lights at night, and the resultant effect will be equivalent to the feeling during the day. Therefore, in the design of LED lighting engineering, we do not necessarily need to obtain the same effect as during the day. It is important to show the characteristics of the building.
