Design Lighting
Designing lighting is a complex and important task that requires careful planning and execution. There are many different companies that specialize in designing lighting, but not all of them are created equal. When it comes to finding the best company to design lighting for your home or business, there are a few things you should keep in mind.
Overview
The purpose of architectural lighting design is to balance the characteristics of light within a space to optimize the technical, the visual and, most recently, the non-visual components of ergonomics with respect to illumination of buildings or spacesThe technical requirements include the amount of light needed to perform a task, the energy consumed by the lighting within the space and the relative distribution and direction of travel for the light so as not to cause unnecessary glare and discomfort. The visual aspects of the light are those that are concerned with the aesthetics and the narrative of the space (e.g. the mood of a restaurant, the experience of an exhibition within a museum, the promotion of goods within a retail space, the reinforcement of corporate brand) and the non-visual aspects are those concerned with human health and well-being.As part of the lighting design process, both cultural and contextual factors also need to be considered. For example, bright lighting was a mark of wealth throughout much of Chinese history, but if uncontrolled bright lights are known to be detrimental to the effect of insects, birds and the view of stars.
Lighting parameter
Lighting plays a critical role in architecture. It can create different moods and ambiances, help to define spaces, and highlight certain features. There are many different lighting parameters that need to be considered when designing a space, such as intensity, direction, color, and distribution. The intensity of light can have a big impact on the overall feel of a space. A lower intensity will create a more relaxed atmosphere, while a higher intensity can make a space feel more energized. The direction of light is also important in creating the desired effect. For example, up lighting can make a space feel taller and more open, while down lighting can create a cozy and intimate feeling.
BEAM ANGLE
The beam angle is the measurement of light's distribution - the angle at which the light spreads out from the light fitting. Beam angles are measured in degrees, from the peak of the light's intensity, to where the intensity drops off at around 50%
LUMENS
In simple terms, Lumens (denoted by lm) measures the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear.
LUMINAIRE
Complete lighting unit, consisting of one or more lamps (bulbs or tubes that emit light), along with the socket and other parts that hold the lamp in place and protect it, wiring that connects the lamp to a power source, and a reflector that helps direct and distribute the light.
CRI
Color Rendering Index (CRI) is a measurement of how natural colors render under an artificial white light source when compared with sunlight.
CCT
Color temperature (Correlated Color Temperature) is essentially a gauge of how yellow or blue the color of light emitted from a light bulb appears. It's measured in the Kelvin unit and is most commonly found between 2200 Kelvin degrees and 6500 Kelvin degrees.
NGR
Non-Glare uses diffusion mechanisms to break up the reflected light off the surface. Diffusion works by reducing the coherence of the reflected image, making these unwanted images unfocused to the eye
