From the point of view of maintenance and cleaning, due to the high hanging height of the deep light, the cleaning and maintenance is relatively difficult. Therefore, the luminaire should be kept clean for a long time, and the enclosed luminaire is better. The advantages of the deep light are high efficiency and long life. The disadvantage is that the one-time investment is large. Aluminium illumination of a commercial building atrium in a commercial building in the atrium. In addition to the use of deep-lights alone, floodlights are often used for auxiliary lighting. This method is especially suitable when the deep light is too concentrated in a certain area, the surrounding area is not illuminate enough, the height of the atrium is large, and the ground illumination is not enough.
Compared with direct-type luminaires such as deep-lights, the ground level illumination provided is low, and the simple traffic atrium is not suitable, but the rooms, cylinders, railings and various facilities in the atrium space around the atrium, such as booths, instructions Cards, greening, seats, etc. can obtain better vertical illuminance, and the texture and color of the materials can be fully expressed. It is suitable for the atrium with strong display and leisure. Large decorative chandeliers are often used in atriums with large investment, artistic strength and high environmental requirements. They can also be used for general lighting. The chandeliers with magnificent appearance can also become the visual center of the atrium. The disadvantage of decorative chandeliers is that the lamps are expensive, the power consumption is large, and the cleaning and maintenance is difficult. If the number of chandeliers is too large or the appearance of the lamps is too complicated, it is easy to produce a cumbersome feeling.
For illumination of taller plants in the atrium, a floodlight that illuminates from the bottom up can be used. Its position should not interfere with the line of sight and glare should be avoided. For lower-light plants, such as flowers, lawns, etc., small spotlights can be hidden in plants for illumination, but it should be noted that the position of the spotlight should be more concealed, and it will not interfere with the line of sight. A low-power bulb to avoid burning plants.
Another way to illuminate low-light plants is to use garden lights. It has many types and various forms. Because of its compact shape, reasonable light distribution and glare, it can be friendly, warm and stable. The atmosphere, therefore, the atrium green lighting uses more garden lights. The evenly diffused garden light can also be used for the illumination of the rest seat of the atrium, which can illuminate the rest of the person's face and facilitate the conversation. Underwater lighting includes two types of simple underwater lights and closed underwater lights that are exposed in water. Simple type of lamp, the neck part of the lamp is equipped with a waterproof member, and a reflective type bulb is used. The installation location is limited to places where they do not enter, and the lamp is small and easy to install. The sealed type can use the various light sources mentioned above, but the specified light source and wattage must be used as required, otherwise there will be accidents such as glass damage in front of the lamp. In addition to the use of the above lamps to achieve lighting effects, atrium atmosphere lighting often uses reflective lighting.
It is a kind of illumination method that hides the light source in the light trough and uses the ceiling to wear the wall surface as the reflective surface. It has the characteristics of indirect type lamps, and the light diffusibility is good, especially suitable for the atrium with small skylights and high environmental requirements. Since the reflective illumination can form a large uniform illumination surface, some atriums that do not have window opening conditions even use it to simulate the skylight. In combination with other lamps, such as lamps, chandeliers, spotlights, etc., the light strip formed by reflective illumination can produce a strong sense of layering. Reflective lighting is currently the most used lighting method in atrium atmosphere lighting.
The items displayed in the atrium are mostly popular items that are mainly launched, including three-dimensional exhibits and flat exhibits. For the illumination of three-dimensional exhibits, the floodlights are mostly used. For large-scale three-dimensional exhibits, such as motorcycles and bicycles, the high-powered floodlights are fixed on the corridors on both sides of the atrium, and the exhibits are obliquely illuminated. The illumination of three-dimensional exhibits, such as clothing and cosmetics, often uses small, spotlights with unique shapes and flexible positions. For the flat exhibits such as advertising posters and art photos, in addition to the use of various power floodlights, many display atriums often design the display bar as a luminescent panel to highlight the display effect. For the illumination of three-dimensional exhibits, attention should be paid to the three-dimensional, texture and color of the exhibits, while for the illumination of the flat exhibits, attention should be paid to the expression of color and clarity.
The appearance of the floodlights must be beautiful and coordinated with the atmosphere of the atrium. At the same time, the scale should not be too large to avoid being overwhelmed. In addition, the light source used to display the illumination must have good color rendering and should be above. In the specific design, there are still many lamps to choose from, this article can not be introduced one by one. However, the principle to be mastered is that when designing the atrium lighting, the lighting design should be based on the different functional requirements of the atrium and the characteristics of the indoor space. Selecting efficient and well-distributed lamps and suitable light sources to create a high-quality indoor light environment. .
