What is main lighting? What should I do?

Without the main lighting, you can design your own lighting layout after reading it.

Take good care of APP users @ Hip Brother. During the renovation, I have been studying the lighting without main lights, doing experiments with my own home, and also touched a lot of doorways. He made detailed notes for your reference ~

Long warning, it is recommended to like the collection first and then look at it!

Decorating my home is a big turning point in my life, purely because I want to do one thing well and give my lover a home (although I was dumped, I have now converted to Tibetan Buddhism). From the beginning, I felt simple and indifferent, from looking for a decoration company to asking the foreman to work privately until I was alone, from designing in a decoration company to asking independent designers to design the whole house by themselves. Always remind yourself that you can't relax, because the occasional escape will bear the consequences for your future relaxation, whether mentally or in action. Maybe you didn't notice, maybe you suffered silently.

Special statement: the lighting arrangement mentioned in this article is spotlights! Turn on the light! Turn on the light! Promise me you won't mention downlight again! ! ! )

A, lighting science knowledge

1, "spotlight and downlight" (beam angle)

This is the most easily broken concept of decorating Xiaobai in one second! Seeing the beautiful lights in other people's homes, the lights I bought carefully turned pale as soon as they were turned on. Many people think that the spotlight is protruding and the downlight is embedded in the ceiling. Anyway, there is no difference in appearance, and the actual lighting effect is different! I believe that many roommates' homes are more beautiful during the day than at night, because ceiling lamps and downlights will not make their homes more beautiful. If your requirement for lighting is only lighting, then you don't need to read the following article.

Spotlight has completely changed modern lighting design, and the demand of lighting design is not only bright. The sense of beam of light and the sense of spatial layering in light and shade create a sense of stage at home, and at the same time, it also gives seemingly illuminated objects a sense of time stillness.

When it comes to the difference between spotlight and downlight, we should mention a key parameter "beam angle". Beam angle means that 50% of the light of the whole lamp is within this angle. Beam angle is not the real angle, and the real spot will be much larger than the marked beam angle (I blindly measured 24 beam angle, and the actual spot is around 48). My own blind definition of the concept of spotlight is that the beam angle is less than 45, and 24 is the most suitable angle for wall painting and home use. Generally, all spotlights in the home can choose 24.

2. Color temperature

This is the most tangled concept of Xiaobai! I don't know what the color temperature is. Conscious thighs won't go to Baidu to copy some concepts for everyone. Household color temperature is generally between 2700 K and 4000 K, and I can't stop it if you say 5000K or 6000K K..

What bothers Sumitomo most is to choose 3000K or 4000K! ! ! You asked me what to choose. Although my family chose 3000K at that time, if God gave me another chance, I would definitely choose 3500K! 3500K can definitely save the difficulty of color temperature selection! The main reason why the family didn't use 3500K before was that the quantity was too small to meet the minimum order quantity of the manufacturer, so the reality could only treat each other coldly.

Focus! Different decoration styles, recommended color temperature:

2700K？ Chinese style (carved mahogany sofa in the whole house)?

3000K？ New Chinese style, Japanese style, Southeast Asia, European court, American style?

3500K？ Nordic, simple, modern, minimalist, mashup?

4000K？ Violent industrial wind?

5000K、6000K？ Rental house style

Comparing different color temperatures together, the low color temperature will turn yellow and the high color temperature will turn blue.

3. Strength

Apart from the color temperature, the most frequently asked question is: "Brother Leg, is 8W too bright for the bedroom?" "Brother Leg, how about the bedroom with 5W and the living room with 8W?" "The elder brother of the leg, there is only one lamp in my toilet. Can you get me a 20W one? " ……

Every time I see this question about power, I wonder how to fool. It's really a super hard question to fool. First of all, everyone has different sensitivity and requirements for brightness. I think it's bright. Maybe you think it's too dark.

I assume that you know how much power you need. When your quantity is small, the factory is willing to give you the same lamp with different power, and the installer can distinguish the specific installation location of different power ... provided that you also understand that different brands have different lighting effects, and every room in the house is empty.

The range of luminous flux required ... I think I'm worried enough about the decoration, but the power of every lamp in my house is the same. Don't complicate simple problems, many things are negative and positive.

Focus, the floor height is less than 3.5m, domestic, the embedded spotlight power is 5 ~ 8W, and the surface mounted spotlight and track lamp are 8 ~ 10W.

4. Color rendering

Color development is also the ability to restore the color of an object through illumination. The more complete the spectrum, the better the color rendering, and the closer the object is to the real color.

Color rendering is generally the most demanding requirement of designers for lamps. Generally, lighting with color rendering above 90Ra can be regarded as high-quality spotlights. Lighting designers with higher requirements generally look at other color rendering parameters. You don't need to know much about this, just remember to pay attention to CRI≥90Ra when watching the lamp. Why not 95Ra and 97Ra? Generally speaking, the higher the color temperature, the more difficult it is to handle color rendering. Chips of the same brand and model can achieve CRI≥95Ra, and chips of 3500K and 4000K can only achieve CRI≥90Ra.

Step 5 glare

Glare is simply glare, which makes people feel uncomfortable. Even if it is a deep anti-glare spotlight, there will be glare directly below the spotlight. When designing lighting, anti-glare has always been the starting point of my design. All spotlights must be designed and cannot be directed directly. Comfort must be considered before beauty at home, especially Xiong Haizi.

For example, on the sofa (this is super into the pit), on the pillow (there are many such hotels, who knows who is lying down), on the chair, on the desk ... Try to use the spotlights with adjustable angles as little as possible. You said that you saw many roommates' sofa background walls and bedside background paintings were so beautiful that you had to wash the walls in order to take good photos, and I couldn't stop you. Don't drive when you are sitting on the sofa and lying in bed. You said you were driving? It's none of my business that you are blind. And you have to run to the light, I can't stop it and I don't want to stop it.

The anti-glare of the spotlight itself is really super important! !

Second, there is no ceiling and no main light.

To make a more exquisite and perfect lighting without a main lamp requires a suspended ceiling, a large flat roof is the best, and a side crane can barely achieve the effect. It is difficult to make a good lighting effect without a ceiling.

Houses nowadays are generally high and low. Many households don't like suspended ceilings and don't want to install headlights, crystal lamps and ceiling lamps. You can choose to use the combination of track lamp+surface mounted spotlight+auxiliary lamp (desk lamp, fishing lamp, wall lamp, etc.). ) to realize the main lighting of your home.

(Track light, 2m track, 4-light effect, 38cm from the wall)

But it is very important to communicate with the electrician in advance and be prepared to be despised and disliked by the electrician. Determine the position of slotting and thread leaving on the ceiling, and let the electrician wrap the thread on the ceiling with yellow wax pipe. It is not recommended to use too many independent exposed spotlights, because the current floor is generally thin, and the slotted position will be more prone to cracking in the future. In general, the power cord can be left at one of the left and right ends of the track lamp. The track length is generally 0.5m~2m ~ 2 m, and the combined length can be freely spliced according to the actual situation.

It is suggested to choose black for the track light, because the track light is generally used for smallpox, and the white track suddenly exposes the unevenness of smallpox. The white track is generally different from the white of smallpox, and the white track is still black, which is obsessive-compulsive disorder.

Third, the light band.

In my opinion, the more perfect main lighting is the combination of spotlights and light strips, which not only brings a sense of atmosphere, but also provides basic lighting. Many people still like the sense of space with all bright lights. Reasonable use of light strips in some places in the home can provide a comfortable diffuse reflection lighting environment.

Let's talk briefly about light bands, because the main focus is on shooting lights. At present, the mainstream light strip is T5 tube, and the traditional soft light strip is rarely used in home decoration with some requirements. The light belt often has a positive light trough and a negative light trough, and the negative light trough needs to be hung with the ceiling, each with its own advantages and disadvantages. There is no need to know how to do it and the specific size. Just tell the carpenter whether to make a straight trough or an inverted trough. If the master can't do it, it is recommended to change people and not stay.

Suggestions on light belt: In many places where curtain boxes are made, reflective grooves can be used instead of curtain boxes according to the actual situation. It's still beautiful that the light of the ribbon is sprinkled on the curtains, but you should leave the power supply in advance when you do water and electricity.

Fourth, lighting circuit control

In lighting design, the circuit design of lighting switch is very important. Remember to make more loops when making water and electricity, try to control less than five spotlights with one switch, and rationally distribute the lighting loops so that the lights can combine different lighting effects and functions at different times and occasions. Try not to use one or two switches to control all the lights, design the switch circuit according to the frequency of use, the arrangement of moving lines and the sequence of distance switches, and design the switch combination mode of double control or even three control according to the living habits, which can feel the concern of humanity in daily life and reduce the contradiction between husband and wife.

(Make more lighting control loops)

! ! ! ! ! The lamp position cheated! ! ! ! !

Formula: there is a wall against the wall, a cabinet according to the cabinet, and a painting; Control distance, design light and reduce glare; Do more loops, functional areas, and supplement lighting.

The biggest difference between traditional downlight layout and spotlight layout is the distance between the lamp and the wall. Downlights are generally far from the wall, and spotlights are generally close to the wall.

Hit the point! ! The two most important distances of lighting arrangement are:

1, distance from the wall

The wall here is not a real wall, but a facade where light needs to play. In some places, there are cabinets, mirrors, cabinets, hanging cabinets and bookshelves, subject to the distance from the outermost facade. Distance from the wall refers to the distance from the center (not the edge) of the lamp to the wall. Generally speaking, embedded spotlights and surface-mounted spotlights are 20 ~ 40 cm away from the wall, and the best effect is about 25 ~ 30 cm. The track lamp is 40 ~ 60 cm away from the wall, of which about 45cm is the best; Linear spotlights (what the hell? ) 40 ~ 60 cm away from the wall, of which 50 ~ 60 cm is the best.

Generally speaking, there is a misunderstanding in opening holes, that is, opening holes in the middle of the ceiling, which is how most workers open holes. It is suggested here that unless the distance from the upper wall is just right. Never open a hole in the middle! ! ! ! It is very important to open holes at a suitable distance.

2, lamp spacing

The distance between lamps is the distance between two lamps. Generally, the distance between embedded spotlights and track lights is 50 ~ 200 cm, and the distance between linear spotlights is 1 10 ~ 140 cm.

The distance between lamps is very large. Why? Because it mainly depends on the actual scene, the situation of each household is different. It is not a meter if it is not a good meter, a centimeter or a millimeter. According to the actual situation of the construction site, first determine the position of the spotlights at both ends, and then divide them according to the length of both ends. Sometimes the mix of different lamp distances will be more design-oriented than simple division.
