LED light have many advantages over incandescent light sources including
lower energy consumption
improved physical robustness
Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes and room lighting.
What is lighting?
Lighting is the deliberate use of light to achieve a practical or aesthetic effect. It includes the use of both artificial light sources like light fixtures, as well as natural illumination by capturing daylight.
Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings and can save energy in place of using artificial lighting.
Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design.
Spot light is a powerful lighting instrument which projects a bright beam of light onto a specific place. It often has a high-intensity discharge lamp with a high color temperature. It’s usually used in places such as painting fixtures, display cabinets or exhibitions to showcase their products.
Down Light (Recessed light)
It is a light fixture that is installed into a hollow opening in a ceiling. When installed it appears to have light shining from a hole in the ceiling, concentrating the light in a downward direction as a broad floodlight or narrow spotlight.
There are three parts to a recessed lighting fixture: housing, trim and bulb. The trim is the visible portion of the light. It is the insert that is seen when looking up into the fixture, and also includes the thin lining around the edge of the light. The housing is the fixture itself that is installed inside the ceiling and contains the lamp holder.
Cove lighting is a form of indirect lighting built into ledges, recesses, or valences in a ceiling or high on the walls of a room.
It directs light up towards the ceiling and down adjacent walls. It may be used as primary lighting, or for aesthetic accent, especially to highlight decorative ceilings.
Colour Temperature It is the temperature of an ideal black-body radiator that radiates light of comparable colour to that of the light source. It is expressed in kelvins, using the symbol K, a unit of measure for absolute temperature.
There are several colour temperatures such as extra warm white which are 2700k, warm white which is 3000k, white which is 3500k, cool white which is 4000k, daylight which is 6000k and cool daylight which is 6500k.
