Exploring the lighting problem of the facade of the building

In the specific design, multi-lamp, multi-beam angle, multi-group lighting, and building facade floodlighting fixtures should be selected according to the special interaction of the building to meet the requirements of use. The table lists the illumination points, the projection distance, and the luminaires that use the beam angle. The location of the luminaires is closely related to the environment surrounding the building. Generally, it should be considered to install floodlights in the following places near the green belt, so that the lighting fixtures should be in a hidden place. Set up floodlights on the sidewalk. At the skirt of the building. A pitching lighting fixture is placed along the front of the top floor. The rest of the project should be combined with the overall environmental location of the building, taking into account the location of the luminaire to meet the requirements of the projection surface, and should not produce direct dark light.

When setting up a floodlighting fixture from a building, the ratio of the distance to the height of the building should not be less than to ensure uniform illumination. The illumination processing method should be such that the projection direction of the light and the viewing direction are at an angle to each other. The building is circular with a round tower, a TV tower, etc. The illumination treatment method uses a narrow beam or a medium beam floodlight fixture to set two or three projection points around the round tower and project the beam as far as possible. Wide beam luminaires are suitable for low-rise building façade lighting, and medium beam and narrow beam luminaires are suitable for high-rise building façade lighting.

When the facade of the building is a flat surface, the light source can be placed close to the facade of the building to make it have a dark and bright effect, and the floodlighting fixture can be adjusted to make the illumination uneven and enhance the artistic effect. When the facade of the building is a line, the beam is generally projected from the left and right sides of the façade to emphasize the façade, and the wide beam luminaire is used to project the soft shadow on the façade. When the façade of the building is a horizontal line, the lighting fixture must have a large distance from the building to make the façade produce a better shadow effect. The calculation method of the building facade lighting is commonly used in building facade lighting. There are two methods, namely the lumen method and the luminous intensity method.

The lumen method is used to solve large architectural aspects, and the luminous intensity method is used to solve monuments such as towers and spires. Using the lumen method to calculate the floodlight coefficient art, the light channel of the original floodlight can be found by the sample using the light intensity method to calculate the floodlight coefficient, and the light source projection direction and the ground clip angle are in the form of a few floodlights. Can be found by light intensity samples. Concluding remarks Facade lighting is an architectural art lighting with strong professionalism. The lighting effect is good or bad, and the impact is large. Therefore, we should be cautious when designing the facade lighting of buildings. In the design, the illumination surface can be estimated first to determine the number of lighting fixtures and the general installation position. The buried power line is given in the design of the drawing.
