Localized lighting allows to distribute the light on a regular basis as the uniform illumination, but the placing of the luminaires must be well studied in order to achieve the desired lighting. You can use natural and artificial lighting that allow creating light intervals or different atmospheres and ambiances.
What is an example of localized lighting?

Warm Light resembles the color of an incandescent; looking orange or yellow. Cool White ranges from Yellow-White (3000K) to White (4000K) to Blue-White (5000K).
What are the benefits of daylighting?

Definition of indirect lighting : lighting in which the light emitted by a source is diffusely reflected (as by the ceiling)
Which are the categories of work related lighting?
Office and workspace illumination can be broadly classified into two categories: General Lighting and Workplace Specific Lighting.
What is electric lighting?
Electric Lighting: The amount of light, the colour of the light itself and the colour that objects appear vary with the type of electric lighting. The lighting must match the workplace and the task. The following are common types of bulbs. * Bulbs are often referred to as lamps in many technical publications.
What is indirect light?
Indirect light fixtures are usually used in offices. Shielded light fixtures use diffusers, lenses and louvers to cover bulbs from direct view; therefore, helping to prevent glare and distribute light. Diffusers are translucent or semi-transparent (see-through) covers made usually of glass or plastic.
What is the difference between a little light and an indirect light?
They are usually used in "clean" manufacturing areas. Indirect light fixtures distribute 90 to 100 percent of the light upward. The ceiling and upper walls must be clean and highly reflective to allow the light to reach the work area.
What is a lens?
Lenses are clear or transparent glass, or plastic covers. The lens design incorporates prisms and flutes to distribute light in specific ways. Louvers are baffles that shield the bulb from view and reflect light. The baffles can be contoured to control light and decrease brightness.
Why is good lighting important?
Good quality lighting also reduces the chance of incidents and injuries from "momentary blindness" ( momentary low field vision due to eyes adjusting from brighter to darker, or vice-versa, surroundings). The ability to "see" at work depends not only on lighting but also on: The time to focus on an object.
Is a light fixture appropriate for every situation?
No single type of light fixture is appropriate in every situation. The amount and quality of lighting required for a particular workstation or task will determine which light fixture is most suitable. Direct light fixtures project 90 to 100 percent of their light downward toward the work area.
Does sunlight reflect light?
Yes. The " colour" of an object actually depends upon the colour composition of the light itself as well as the colours of the light that the object reflects and absorbs. Natural sunlight is made up of all the colours of the rainbow (spectrum): red, orange, yellow, green, blue, indigo and violet.
What is direct lighting?
Direct Lighting. In a direct lighting system, 90 to 100 percent of the light from the luminaire shines toward the work surface. This is the most common type of lighting and is used for many types of tasks. The area that is lit depends on the characteristics of the luminaire.
Why do offices have uniform lighting?
Most offices have uniform lighting, because workers must be able to use the available lighting anywhere workstations can be set up. Yet, under certain conditions, adequate illumination can be provided by non-uniform lighting, saving up to half the operating cost of a uniform lighting system.
How much of the light from a luminaire is diffused?
In an indirect lighting system, 90 to 100 percent of the light from the luminaire shines upward and reflects off the ceiling. Indirect lighting should result in highly diffused, evenly distributed light. The ceiling is the main source of light in this type of system, so it should be completely and evenly lit.
What percentage of the light is reflected in a semi direct light fixture?
In a semi-direct lighting system, 60 to 90 percent of the light from the luminaire shines toward the working surface. The remainder of the light is reflected toward the ceiling and the upper portion of the walls. This lighting system softens shadows and produces even lighting. Semi-direct and direct lighting have many characteristics in common. As is true with a direct lighting system, unless the fixtures are properly arranged, reflected light or shadows can be a problem when using semi-direct lighting.
How much of the light from a luminaire reflects toward the ceiling?
In a semi-indirect lighting system, 60 to 90 percent of the light from the luminaire reflects toward the ceiling. Highly reflective ceilings and room finishes are important, as is good surface maintenance. This method of lighting produces a very pleasing room ambience while also providing several good reading areas.
What is non uniform lighting?
In a non-uniform lighting system, the fixtures are placed high or close to the ceiling, but the spacing between them is irregular. The placement of the fixtures is determined by the location of workstations and machinery and the nature of the task that will be performed in that area.
What percentage of light is distributed in a room?
In a general, or diffused, lighting system, light is distributed equally to both the upper and lower areas of a room—50 percent upward and 50 percent downward. While general lighting can be pleasing to the eye, it can seem harsh to some. Therefore, a more indirect method of lighting is often desirable.

Why is task lighting unique?
Of the three, task lighting is the most unique, because it has to work for what you do in each room while blending with the other lights. It is necessary to consider the specific activities that will be conducted in each space, in order to determine how this will affect the lighting design of each space.
What is the easiest type of task lighting?
Lamps are the easiest type of task lighting to place and move around your home.

What is local dimming?
Local dimming can be a way to get near-OLED levels of picture quality. Or, it can offer some improvement compared with basic TVs, creating a pleasing, if not class-leading, image. Or, it could be a marketing label for something that's not really much benefit at all.
Where are LED lights on TV?
The most common variety of LED LCD is edge-lit. With edge-lit LCDs, all the LEDs are along the edge of the TV, facing the center of the screen. Local dimming, in this case, becomes a bit looser of a term.
What is each zone responsible for?
Each zone is responsible for a certain area of the screen. Objects smaller than the zone (stars in the night sky, for example), don't benefit from the local dimming, and can look muted as a result.
Does an LED LCD have contrast?
LED LCDs don't have the contrast ratio potential of OLED (or plasma, may it RIP). As such, their images don't have quite the depth and three-dimensionality that's possible with other technologies. Local dimming was developed to improve this aspect of LED LCD performance. By dimming the parts of the screen that should be dark (a character in shadow, ...
How successful is Control4 panelized lighting?
successful Control4 Panelized Lighting installation is best achieved when the electrician and the Control4 Dealer communicate early and regularly throughout the project (see the Control4 Panelized Lighting Planning Guide for Dealers). In doing so, the potential for time-consuming and costly changes are greatly reduced.
Where is the electrical wiring located in a centralized panel?
In a centralized panel design, the electrical wiring for all lighting in the home or business is routed through one or more centrally-located panels (typically in an equipment closet or utility room) before being run to the lights throughout the home or business (see Figure 3).
What is hybrid lighting?
hybrid system design combines a centralized or distributed layout of panels with localized Control4 or conventional switches and dimmers placed in key locations throughout the home. This design allows for traditional lighting control in areas such as guest rooms, closets, etc., where a low-voltage keypad is not desired (see Figure 5).
What is distributed panel design?
distributed panel design is similar to a centralized panel design, but includes two or more panel locations throughout the home. In this design, circuits are routed from the breaker box to designated panel locations and then to the loads (see Figure 4).
