Misunderstanding of the "definition" of no main light
Without the main light design, 90% of people will literally understand that there is no main light, such as chandeliers, ceiling lights, etc., and the entire indoor space relies on auxiliary light sources (spotlights, downlights) to obtain illumination.
However, there is no main lamp design in the designer's mind, and there are two other meanings:
1. There are chandeliers or ceiling lights, but they are only used for decoration, without light sources or not turned on, and rely on auxiliary light sources to obtain lighting functions.
2. There is a main light and a light source, which can be turned on, but the brightness is very low, not enough to support the lighting function of the entire space, and the auxiliary light source can provide indoor space lighting at the same time.
The above interpretation can be called a design without a main light, but in summary, it is necessary to have an auxiliary light source to provide illumination. It does not matter whether the main light is present or not, so no main light is not an appropriate name. It is just a form of lighting. At the beginning, it may be a marketing method for designers or design agencies to get a "tall" title and attract more trendy people.
Therefore, no main
lamp design has become a trend of "word of mouth" by the younger generation of trendy people, and it is deeply "misunderstood". The author thinks that no main lamp design can only be misunderstood as its literal meaning. It should be understood as a kind of "style" of lighting, just like in decoration, light luxury style, black and white gray style, etc., non-main light should be called non-main light style design in the future.

Misunderstanding of "Use" Without Main Light
Some time ago, a friend consulted about the design of a masterless lamp at home. In the ceiling position, several downlights and several spotlights are needed, how to arrange them and other issues. I felt that there was "sufficient speech" at the time. The lamp design style has been "misunderstood" to the extent that it can be achieved simply by installing a few spotlights and downlights on the ceiling?
Strictly speaking, the design style without main light should originate from coffee bars, bars and other places. In order to create a mysterious and warm atmosphere, "general lighting", "partial lighting", "directional lighting", "key lighting", "
Flood lighting", "transitional lighting", "
landscape lighting" and other methods. Later, this lighting method was used by designers in the high-rise space with higher floors, and finally gradually developed into the application of various apartment types. In fact, this trend is misunderstood, not all units are suitable for the design of the style of no main lamp.
①The unit type with too low floor height is not necessarily suitable for the design without main lamp style.
②Among family members, those with elderly and children are not suitable for the design style without the main lamp.
③In the long run, although young newly-married couples like the lighting of this atmosphere, with the baby in the future, this design without the main lamp will be very tasteless.
If you really like the style of the main lamp, it is recommended to install a main lamp, even if it is not turned on normally, it is better than regretting it in the future. If you want to use the main lamp style well, you must first understand the basic optics and then interpret the main lamp. Main lamp style, and master the expression form of design style without main lamp.

Essential knowledge of optics
If you want to understand the expression of the design style of the headless lamp and interpret it, you need to understand the basic knowledge of light first, because in the following explanation, many such professional terms will be used, and these terms will be briefly explained below.
(1) Physical properties of light
Deciphering light from the perspective of physics can roughly start from seven different aspects, namely "illuminance", "color rendering", "color temperature", "shadow", "stability", and "glare".
①Illuminance: refers to the luminous flux received by the illuminated object per unit area, in lux (LX). In indoor lighting design, the illuminance of the area is usually combined with the purpose of the illumination area.
②Light color rendering: refers to the color difference (Ra) of the same object under the illumination of different light sources; for a simple example, the color rendering of sunlight is the best (color rendering index 100), and the incandescent lamp index is 97 , Followed by the fluorescent lamp index is 80~94; but in the design of indoor lighting, the higher the color rendering, the better. For example, the design without the main lamp style uses a lot of light sources with lower color rendering to enhance the atmosphere .
③Color temperature: In simple terms, in the same environment, the higher the color temperature of the light source, the colder and colder it feels, and the lower the color temperature, the warmer it feels.
④Shadow: When there is light, there must be shadow, and the design style without main light mainly uses the atmosphere created by shadow.
⑤ Stability: First, the stability is to pay attention to the load of the electric voltage to avoid the light source flickering, and the other is to pay attention to the airflow to avoid the swing of the lamp.
⑥Glare: Glare is a kind of visual induction caused by the physical properties of light, which makes the eyes feel extremely uncomfortable and accelerates people's visual fatigue. Therefore, the choice of light source needs to consider glare instead of the main light style. Design is the easiest to cause dazzling, and it is mainly because of this. Therefore, the author thinks that without a main lamp, you need to choose carefully and do not blindly follow the trend. Therefore, if you want to design without a main
lamp, you must have a professional lighting designer Guidance can be.

Interpretation of the different expressions of the design style of no main lamp
Without the main light design, the performance of lighting can be roughly divided into nine categories, namely general lighting, partition lighting, local lighting, mixed lighting, directional lighting, accent lighting, reflective lighting, transition lighting and landscape lighting, each The lighting forms all have different design principles.
Only by using these nine items reasonably can you achieve a perfect design style without a main lamp, instead of just relying on a few spotlights and downlights to create a feeling of "darkness", the following nine kinds of The lighting form is briefly introduced.
(1) General lighting
General lighting is the most basic form of lighting. It does not need to consider too many lighting factors. The main purpose is to bring a relatively balanced lighting effect to the interior.
In the non-main light design style, in order to achieve the effect of general lighting, multiple identical lighting fixtures are arranged in a relatively uniform form, so that the space covered by the fixtures can obtain a relatively uniform lighting effect after the power is turned on. This kind of light expression is usually used in the lighting design of corridors and other areas in ordinary lighting design.
(2) District lighting
District lighting is to increase the illuminance of a certain area in the same space according to actual living needs, and the lighting layout used in this area is designed according to general lighting, so that the illumination of the area with increased illuminance is finally balanced.
In the home space, the use of partitioned lighting can improve the quality of indoor lighting to a certain extent, save unnecessary waste and ensure the efficiency of light source utilization.
In the design style of no main light, a large number of zoning lighting methods are used, and multiple light sources are used to make the light softer. We must pay attention to the multiple light sources mentioned here. It is not many downlights in misunderstandings, but may also be Long chandelier.
(3) Local lighting
If the zoning lighting cannot meet the occupants' lighting needs for a certain area, or the general lighting cannot illuminate the area and it is not convenient to install the zoning lighting fixtures, then the lighting arrangement of the local lighting is a good choice.
The local lighting design is suitable for areas with high lighting requirements, such as bedside lamps and desk lamps.
In some larger spaces, there is usually more than one local lighting area. When designing without the main lamp style, I prefer to distribute multiple lighting fixtures in multiple parts of the space to play a role in decorating the space.
(4) Mixed lighting
The light expression form composed of general lighting, district lighting, and local lighting is called mixed lighting.
When designing lighting for large-sized indoor spaces, the living room area usually adopts a mixed lighting design, and the mixed lighting layout used is often relatively complicated, but we can make the lighting layered by reasonable layout. Be organized to avoid unnecessary waste of light sources.
to sum up
The author believes that no main light design should be understood as a style. Strictly speaking, it should be called "no main light design style", instead of being gradually misunderstood as no main light. Use a few downlights and spotlights, simple A light atmosphere can be formed by a single combination; the correct style design without the main light is relatively strict and complicated, and it requires general lighting, partial lighting, directional lighting, accent lighting, flood lighting, transition lighting, landscape lighting, etc. The combination of these methods, mutual cooperation and reasonable collocation can be called the real headless style. At the same time, it is not suitable for all families. You must carefully choose the headless style design according to your family members and floor heights. Therefore, it is recommended not to blindly follow the trend, which will cause light pollution in the indoor space.
