Residential lighting design and LED downlights/LED spotlights, permutation and combination discussion

1: About the dining table

Now more and more of the so-called no main lamp, the pursuit is the whole house, without a floor lamp/chandelier/wall lamp, etc. No main lamp, does not mean no lighting.

In detail, there will be a spotlight flooding. In this paper, we only discuss the arrangement and combination of canopoules, concentrating and flooding, which are explained in detail in my other articles.

The droplight of mensal, from my individual Angle character, it is to rise to illuminate the purpose of mensal not just, at the same time it also has extremely strong adornment sex.

Also, a lot of people can’t tell the difference between different light patterns, and that’s a key point.

Chandeliers, commonly light bulbs, or LED beads, with an acrylic case.

They have a very important point is that they are floodlight lighting lamps and lanterns, the directivity is not particularly strong, not as good as spotlights.

Spotlights, there are many structures, optical design, lenses and so on, very concentrated light.

Some people like to use spotlights instead of chandeliers for table lighting.

So, I’m going to run the simulation in software.

This is a 2.7-meter high space, you can obviously see that with ordinary chandeliers, a value of illumination on the table is within the standard range.

And with a spot light like the above picture, the desktop illumination has been thousands of lux (the center point is 2800 lux), but in the content of the residential code, there should be no such illumination value, more than the standard several times. Of course some say I like namely, that also have no rut, face rascal, I can say only, you are happy good.

This is the spot light data.

And then let’s look at a spot light.

1 spot light, obviously much better.

Not too much. It’s well within the scope of use. (The center is 670 lux)

A lot of people use at random to shoot the lamp, it is the distinction of the light that did not divide the type of clear lamps and lanterns and its place give out.

Chandelier wattage is larger, but it is floodlight category, the desktop will not be too focused, so a human eye looks brightness can also calculate.

But spot light, the thought of a lot of people is: chandelier wattage is relatively large, so I also want to use several spot light together, the same wattage to replace. But what they do not know is that the focus of the light is much stronger.

Again simple to understand is: chandelier this kind of lamps and lanterns, the light emitted is running everywhere, and the spotlight is running vertically.

The amount of light used on the table is determined by the size of the table top.

As shown in the figure below.

Another point by the way, in residential space, with spotlights to illuminate the desktop, the selection of lamps and lanterns is also the main.

Light range as far as possible to cover the entire table, do not need to be like some high-end western restaurants, only a beam of light in the middle of the table. There’s no need for drama at home.

2: About the living room

I’ve seen a lot of them, and they’re all in the middle, or several of them. One at each of the four corners of the room.

What I always say is, is this lighting design? Any other person could draw it like a CAD.

I’ll start in the middle of the living room.

Personally, I suspect a lot of people think that way.

The living room used to be the main light with a larger wattage. So WHEN I use no main lamp, it must be to use several spotlights to replace it.

In this way, we can achieve almost the wattage of the lamps and lanterns.

I see a lot of people buying this kind of lamp.

It is also because jack Ma now sells a lot of these, but also exclusive lighting.

It’s really about doing whatever it takes to get the most out of it.

To quote what I said at the beginning: they think that the wattage of the chandelier is relatively large, so I have to use several spotlights to illuminate the same place, the same wattage to replace. But what they do not know is that the focus of the light is much stronger.

Not only that, but a lot of so-cal led tape lighting designers love spotlights with a small light range throughout the house, and I still don’t know why. It’s a long story to tell these people.

You can see clearly, with chandeliers, or ceiling lights and things like that, the wattage is large, but the space will light up.

But you use spotlights, even if you have four heads in the middle of your living room. It was still dark. It won’t light up.

This is just enough, but because there are several spotlights in the middle, some people said to me that the actual feeling is just like the little sun, and I never turned on this lamp again.

Of course, I didn’t actually experience it, after all, I, and all around me, didn’t know where to find such a poorly designed place to experience it.

Now I’m going to give you a sense of the four corners of this space with spotlights.

The value of the first picture, you can think of it simply as a quantization of how bright this place is.

Figure 2, we can actually feel that the light and shadow in this space is too large than the column.

But the person is in this kind of space, can not have very big easy at all, this also is a lot of so called do not have advocate lamp in the home come out roughly state.

But in the national norms, not only to each space place to do exactly how bright a plan, and, also, the wall and ceiling also made a standard. It’s a percentage ratio.

A simple example is your living room, 0.75 horizontal plane is the X value of light, so the wall and the top of the light, need to account for a percentage of the X value.

The reason for this is to avoid excessive smooth light and shade, so that the contrast between light and shade is not too large, leading to the rapid decline of eye fatigue value, making people uncomfortable.

Of course, some people will tell me that I see the Japanese side as the middle four lights, but they are downlights, not spotlights in your small light range. That’s the big difference.

Look at the light range. And look at the range of light with spotlights. Not the same.

3: The rest of the space

It is still the same. Before using the lamp, I want to know clearly how much light this place needs, and then match the appropriate lamp. Otherwise, there will still be all the problems I wrote above.

4: About others

Some people tell me, like a lot of lights together. I’ll just go with the low wattage.

Logically yes.

But one thing to note is that these people certainly do not understand the lighting industry.

First of all, the 3-5W lamps sold by Philips on Jack Ma are very bad lamps, which are projects to increase the company’s extra high income. One way to think about it is this.

A lot of other small wattage spotlights, basically to showcase lights. It is not a lamp used for basic lighting on the ceiling.

The end of this article, I hope to help you.

Several spotlights together, from my personal point of view, I do not feel very beautiful, not only that, the light is not reasonable. I don’t know why so many people like it.

Finally, I hope everyone can have a comfortable and healthy light environment.
