Exterior Light control of Haiyabinfen Plaza

Architectural lighting design is a field within the fields of architecture, interior design, and electrical engineering that involves the design of lighting systems, including natural light, electric lights, or both, to meet human needs.

The design process takes into account:

The type of human activity that will provide lighting

required amount of light

The color of the light can affect the line of sight of specific objects and the environment as a whole

Light distribution in an indoor or outdoor lighting space

Mitigate the impact of the system itself on users

Lighting design is designed to be a human response to see clearly without discomfort. The purpose of architectural lighting design is to facilitate the architectural design or experience of buildings and other physical structures.

In 2016, Vteck and Baoan Haiya binfen Plaza jointly designed the exterior lighting of the building, using multiple DMX512 dimmers to design the colorful exterior lighting of the building. Perfectly realize the matching of lighting and architecture,

concept

Architectural lighting design focuses on three fundamental aspects of building or space lighting. The first is the aesthetic appeal of the building, which is especially important in the lighting of retail environments. Second, in terms of ergonomics: measure how well the lighting functions. The third is energy efficiency, ensuring that no light is wasted by over-lighting, which occurs by illuminating empty spaces unnecessarily or by providing more light than is required for aesthetics or tasks. Cultural factors also need to be considered; for example, bright lights have been a sign of wealth throughout Chinese history.

Architectural Lighting Design

day lighting

As the sun moves across the sky, it may appear red, orange, yellow, or white, depending on its position. Changes in the sun's color throughout the day are primarily the result of light scattering, not changes in blackbody radiation. The blue color of the sky is caused by Rayleigh scattering of sunlight from the atmosphere, which tends to scatter blue light more than red light.

For colors based on the black body theory, blue appears at higher temperatures, while red appears at lower, lower temperatures. This is in contrast to cultural associations ascribed to color, where red is hot and blue is cold.

lamps

Lighting fixtures come in a variety of styles for a variety of functions. The most important function is to serve as a stand for the light source to provide directional light and avoid visual glare. Some are very simple and functional, while others are works of art in themselves. Almost any material can be used as long as it can withstand the excess heat and meet safety specifications.

An important attribute of a luminaire is luminous efficiency or wall efficiency, which is the amount of usable light emitted by the luminaire per energy used, usually measured in lumens per watt. The efficiency of a luminaire using an alternative light source can also be expressed as the percentage of light delivered from the "bulb" to the surrounding environment. The more transparent the lighting, the more efficient it is. Shaded light generally reduces efficiency, but increases the probability of directionality and visual comfort.

The PH lamps are a series of lamps designed by Danish designer and author Paul Henningsen from 1926 onwards. The lamps are designed with multiple concentric shadows to eliminate visual glare and emit only reflected light, obscuring the light source.

Photometric research

Photometric studies are often used to simulate the lighting design of a project prior to its construction or renovation. This enables architects, lighting designers and engineers to determine whether the proposed lighting setup will provide the expected amount of light. They will also be able to determine the contrast between light and dark areas. In many cases, these studies refer to IESNA or CIBSE recommended lighting practices for these types of applications. Depending on the type of area, different design aspects may be emphasized for safety or practicality. Often used to create these models, usually in combination with 2D digital CAD drawings and lighting simulation software.

The color temperature of a white light source can also affect its use in certain applications. The color temperature of a white light source is the Kelvin temperature of the theoretical black body of the emitter that is closest to the spectral characteristics of the lamp. Incandescent light bulbs have a color temperature of about 2800 to 3000 Kelvin. Daylight is about 6400 Kelvin. Lower color temperature lamps have relatively more energy in the yellow and red parts of the visible spectrum, while higher color temperature lamps have a more bluish-white appearance. For critical inspection or color matching tasks, or for retail displays of food and clothing, the color temperature of the lamps will be chosen for the best overall lighting effect. Colors can also be used for functional reasons.

correlated color temperature

The color temperature of the light source is the temperature of the ideal black body radiator that radiates a comparable hue of light such that the light source's. Color temperature is a characteristic of visible light and has important applications in lighting, photography, photography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature only makes sense for light sources that actually radiate somewhat close to some kind of black body, i.e. lines from red/orange to yellow, or white to blue-white. It doesn't make sense to say the color temperature of green or violet light. Color temperature is usually expressed in Kelvin (Kelvin), the unit of xxx temperature.

For lighting inside buildings, it is often important to consider the color temperature of the lighting. For example, warmer (i.e. lower color temperature) light is typically used in public areas to promote relaxation, while cooler (higher color temperature) light is used to enhance concentration in the office.

CCT dimming of LED technology is considered a difficult task because the binning, age and temperature drift effects of LEDs can change the actual color value output. Here, a feedback loop system is used, for example, with a color sensor to actively monitor and control the color output of multiple color mixing LEDs.

The color temperature of electromagnetic radiation emitted from an ideal black body is defined as the surface temperature, in Kelvin or in Meads. This allows defining criteria for comparing light sources.

Categorize different lighting

To the extent that a hot surface emits thermal radiation but is not an ideal blackbody radiator, the color temperature of light is not the actual temperature of the surface. The light and heat radiation of an incandescent lamp is close to that of an ideal black body radiator, so its color temperature is basically the temperature of the filament.

Many other light sources, such as fluorescent lamps or LEDs (Light Emitting Diodes), emit light primarily by means other than thermal radiation. This means that the emitted radiation does not follow the form of the black body spectrum. These sources are assigned a so-called correlated color temperature (CCT). CCT is the color temperature of a black body radiator, which most closely matches the light of a lamp to human color perception. Since incandescent lamps do not require this approximation, the CCT of an incandescent lamp is its unregulated temperature, which is derived by comparison to a black body radiator.
