    1. Design and arrangement of lighting for houses:

    1.1  Principles of lighting arrangement for the living room:

    During the day, you can make the most of natural light to make the living room space bright and airy.

    At night, the highlight of the living room should be a chandelier or focused spotlight or indirect lighting. This will be a suitable choice for your living room to create a warm, cozy feeling

    The living room should use overall lighting combined with focal lighting to create accents. Living room lighting will depend on the wall paint color. In addition, to enhance lighting efficiency, arrange the lights on the wall at equal distances. You can also install accent lighting products appropriately to highlight an object or a certain corner in the room. For example, you can install lights in many different positions on the ceiling or wall to direct light to a specific object in the room such as a painting, flower vase or decorative vase.

    - Some basic living room lighting design layouts:

    + Calculate the number of lights

    + Choose lights: Based on different types of ceilings, choose different types of lights. For example, types of ceilings such as flat ceilings, level ceilings, concrete ceilings, drop ceilings...

    + The living room space needs to be well lit. Therefore, priority is given to using overall lighting of 4000K- 5000K, Minimum required brightness is about  200 – 300 lux.

    + Use lights such as: Chandeliers, ceiling lights, pendant lights, etc. These lights should be arranged in the center of the room combined with focal lights like Spotlight to increase space highlights. The furniture will help the living room become extremely warm and luxurious

    + Arrangement: Lighting distance for chandeliers should be hung about 2.1 - 2.3m above the floor from the bottom of the chandelier. Ceiling lights need to be 1m-1m2 apart. For LED lights, use a capacity of 6w - 9w with a distance of 1m2 for the living room. Spotlights are spaced about 30 - 50cm apart, type 7w - 12w.

    1.2. Principles for arranging lighting for stairs and hallways:

    When designing lighting for hallways, stairs, and lobby areas, it is best to use indirect lighting.

    For hallways, you can use LED lights deep in the wall and wall lights to create a cozy feeling and eliminate the clutter.

    You should use ceiling lights for straight lighting or you can use wall lights to increase the flexibility and aesthetics of the stairs. You need to correctly determine the total hallway area to determine the appropriate number of light bulbs to use, avoiding waste and insufficient light.

You can use Spotlight lights or Downlight lights combined with indirect lighting. In addition, it is necessary to pay attention to the location of the lamp installation and the direction of the light to avoid causing glare or strong light that reduces sleep quality. Depending on each type of lamp, there will be different installation locations, specifically:

    + To limit the occurrence of dazzling reflections, rows of lights should be placed parallel to the direction of view and the door
    + The light source comes from long lamps that must be arranged and installed in a direction that shines directly from the ceiling.
    + The total number of LED lighting for the office must ensure design standards, and the amount of light is appropriate for working. The light bulb must not cause blinding or blurred colors when working.

    + For some areas such as meeting rooms or director's rooms, priority is given to using Spotlight lights to have a harmonious, cozy space.

    + Lighting when designed in an office needs to ensure the criteria of evenly dividing light in different working areas, minimizing hidden corners such as the location of work cabinets in the office, etc. Because these are also places frequently visited to get work-related documents.

    + Prioritize the use of focus lighting, LED Spotlight to illuminate and highlight products.

    + Give priority to lighting types with a CRI color rendering index of 80-90 or higher. Especially fashion or jewelry items require a CRI level higher than 90 to bring the highest efficiency.

    + Pay attention to using strong light to highlight the background or billboard because this is a location that attracts customers, increases recognition and can easily turn passersby into customers.
