Talking about the lighting design of the home

With the development of modern society, the family as a place for rest and life is more concerned and valued by people. People's requirements for home lighting are no longer satisfied with simple lighting.

(1) The purpose of home lighting:
·Safe, visual and comfortable atmosphere
Common illumination light source (2) 2.1 household incandescent <br> 2.1.1 Normal incandescent lamp of this type are cheap, easy to use, has a variety of power and shape. The basic shape is divided into 3

A general type

B ball type

C shaped

2.1.2 Tungsten halogen lamps have a certain amount of reflective coating inside the bulb, so that the bulb can push the light forward, so that we can control the beam more conveniently than ordinary incandescent lamps.

a.. More efficient than conventional incandescent lamps. There are various beam angles. There are high voltage (120V) and low voltage (12V) voltages.
2.2 Fluorescent lamps use only one-fifth to one-third of the energy of incandescent lamps to emit the same luminous flux, which is longer than those of incandescent lamps.
· Compact fluorescent lamps (energy-saving lamps) can be used in most home lamps. (E27) lamp caps can directly replace ordinary incandescent lamps. Fluorescent lamps can provide a variety of color temperatures. Among them, warm white fluorescent lamps are most suitable for home lighting.

(3) Two ways of lighting
3.1 general lighting,
Uniformly illuminate the ground, work surface and environment to provide a certain level of brightness to ensure the safety of the living,
Can use chandeliers, wall lamps, recessed lamps

3.2 Local illumination Local illumination is the concentrated illumination of working surfaces or objects, such as book desktops, paintings, sculptures, etc. Track lighting, ceiling-mounted spotlights, table lamps, ceiling lamps

(4). Commonly used home lighting fixtures
4.1 Types of lamps (a): chandeliers (this type of luminaire can provide a certain illumination to the room to create a suitable atmosphere)

4.1.1.	4.1.2.
4.1.3.	4.1.4.

4.2 Lamp type (B): ceiling lamp

4.2.1.	4.2.2.
4.2.3.	4.2.4.

4.3 Lamp type (C): wall lamp

4.3.1.	4.3.2.
4.3.3.
4.3.4.

4.4 Luminaire Type (D): Mobile Luminaire

4.4.1.	4.4.2.
4.4.3.	4.4.4.

4.5 Type of Fixture (h): Track Lights

4.5.1.	4.5.2.
4.5.3.	4.5.4.

4.6 Lamp type (i): recessed light fixture

4.6.1.	4.6.2.	4.6.3.

(5) Lighting of the main room
5.1 The center of the restaurant is the dining table. The lighting is required to make the table cloth. Tableware, food, flowers and other bright and beautiful, can cause appetite. It can also create a suitable atmosphere. Common lamps: chandeliers, ceiling lamps, can also be used Wall lights to adjust the atmosphere, if the requirements are higher, dimmers can be used to create more modes, reduce the illumination, and use more flexible lighting to meet the needs of dining and entertainment. E (working surface) = 300 ( Lx) E (environment) = 100 (lx)

5.2 Kitchen embedded fluorescent lamps or ceiling lamps can provide high-quality, energy-saving basic lighting to meet the needs of side dishes and cooking. The choice of lamps should be based on functionality, while requiring waterproof, dustproof and oil-proof (IP65).
Illumination standard: E (working surface) = 500 (lx) E (environment) = 250 (lx)

5.3 Bedroom bedroom is an important part of the family room, the first requirement is that lighting should play a hypnotic role.
Depending on the room, the lighting can satisfy the living behaviors such as reading newspapers, watching TV, makeup, clothes, etc., and should distinguish the illuminance according to the age and lifestyle of the occupants: E (working surface) = 60/300 (lx ) E (environment) = 60 (lx)

Can use ceiling lamps, recessed downlights, mobile lamps or wall lamps

Rocker lights, which are mainly used on both sides of the bed for illumination during reading, and can also illuminate the small furnishings on the bedside table

5.4 The bathroom is in the bathroom and needs lighting to satisfy the activities of shaving, haircutting, makeup, bathing, etc.
The bathrooms are large and small, and in a small bathroom, a mirror headlight can illuminate the entire space with specular reflection.
Illumination standard: E (working surface) = 500 (lx) E (environment) = 200 (lx)

For a light with a mirror that requires both sides of the symmetry to illuminate, this will ensure that the light on both sides of our face is even. It can be mounted on the top and sides of the mirror.

A closed, moisture-proof recessed downlight can be used in the shower.

5.5 Study lighting needs to be able to meet reading, writing and computer work. At the same time, it can consider the highlights of commemorative items such as prizes and photos. Can use ceiling lamps, recessed downlights, mobile lamps, chandelier illumination standards: E (work Face) = 300 (lx) E (environment) = 150 (lx)

The desk lamp gives extra illumination to the desktop and computer keyboard areas. The target of the light cannot directly illuminate the screen to avoid reflection glare.

5.6 The living room is the most used multi-purpose space in the house. It is used for parties. Watching TV, receiving guests and other activities can use chandeliers, wall lamps, spotlights, downlight illumination standard: E (working surface) = 300 (lx) E (environment) = 150 (lx)

6 Lighting design process

7. Benefits of illumination calculations with lighting software such as DIALUX:
a. Professional and accurate b. Intuitive, easy to communicate with all aspects c. Can be easily adjusted and calculated

Example:

8. Some experiences in home lighting design:
8.1 The living room uses a warm light source (2800-3000K) to create a family atmosphere.
For visual health and comfort, the main lamp's lampshade should reflect light upwards and do not reflect downwards.
8.2 Multi-purpose wall lamps, floor lamps and table lamps are used to make a number of partial, scattered light areas, using different combinations of lamps to create different atmospheres.
8.3 Under the premise of ensuring safety and easy cleaning, it is very effective to hide the light source and use indirect reflected light as ambient light.
8.4 Warm light source is better than cold light source. Light source above 4200K is not recommended for home lighting.
8.5 The aesthetics and style of the luminaire cannot exceed the proper choice of the light source, and the simple luminaire is more easily integrated with the home space.

9. Summary:
The development of home lighting requires more involvement of lighting designers to make it easier to create a warm, energy-efficient light environment.
