Talk about the practical application of spotlights

How many watts do I choose for spotlights? What beam Angle? What is the color temperature? That sort of thing. Show that a lot of readers will still step on the spotlights pit, so this article to chat about the actual use of spotlights in household lighting.

The friends who often read my article should be clear, I have always suggested that the use of low-power spotlights, the logic behind this I will be clear in this article, in order to solve the problem of spotlights power selection.

Q1: What are the main application scenarios of spotlights in home lighting?

Highlight illume is one of the action that shoots the light, rough say namely differentiate key and blame key, the area of the key should bright, blame key area should dark.

So, when decorating household illume, be about to consider above all those places are worth to use shoot the lamp to illuminate, and must want to maintain enough dimensional distance between two key, if whole house is key, that also did not have key at all.

Led lighting hanging pictures, is to highlight hanging pictures, so that hanging pictures in the obvious difference from other walls.

Led lighting wall washing, household lighting in the wall washing is more pseudo demand, the reason is very simple, ordinary commercial housing there are no few walls worth washing (most of them).

Led lighting highlights the functional lighting, such as stage basin, washing basin, tea table and other operating surface needs higher illumination, especially in the decoration of no main lamp, because of the scattered lighting, the uniform illumination of the space will not be too high, to meet functional requirements, the spotlight is also a better choice.

Q2: What is the brightness of ambient light when using spotlights?

The following figure shows the value of ambient illumination in architectural Lighting Design Standard:

Let’s just look at the first three:

General activity 100XL,

Dining environment 150LX,

Writing reading 300lx, suitable for mixed lighting,

In using the lamp actually, brightness can exceed bid normally a lot of, do not talk about whether illuminant is wasted temporarily, but true afore-mentioned reference already can satisfy daily need.

I often wordy one word, do not be afraid your home is not quite bright, look at present, the house illumination that decorates newly is not enough just extremely individual case, the illumination of most families exceeds bid N times, eye fatigue this is brightness expregacious the most direct consequence.

The reasons are as follows:

When the pupil is stimulated by strong light, the pupil contracts. When the pupil is stimulated by weak light, the pupil slowly opens. When the pupil dilates, the surrounding muscles are relaxed, and the pupil contracts, the muscles are tense.

So even though you might feel comfortable in a high-light environment, you’ll still feel tired because your pupils are constricted and your muscles are tense.

Spotlights to achieve the effect of prominent lighting, it is necessary to have illumination difference, namely the contrast between light and shade, in the previous article has been described very clearly.

For the convenience of readers, the general summary:

What kind of contrast is more suitable for home lighting?

First look at the glare classification criteria:

Comparison table of glare value parameters

If the chiaroscy ratio exceeds 19, it is defined as glare critical, i.e. the chiaroscy ratio is 20:1.

This is easy to understand, we look up at the naked light bulb, will feel very harsh. The brightness ratio of the bulb to the ambient is more than 20 to 1.

At 10:1, or 9, we can see clearly what’s around us, and it’s a very sharp contrast.

5:1 is the contrast between light and dark is 4, which is what ordinary people think is more beautiful contrast (note: ordinary people), no matter the key point or the surrounding environment can be seen clearly.

3:1, or 2, is the threshold for discernible chiaroscuity, meaning below that it’s hard to tell what’s bright and what’s dark.

Summary of quotes:

In a home lighting scene, even if we love angular lighting, the maximum contrast should be 9. Good visual brightness can be achieved even at low physical brightness.

A chiaroscuro ratio of around 4 is more ideal, which means you’ll still look bright even if it’s not too bright.

Low light and shade contrast suits children room, old person room more, slightly tall contrast suits the scene with strong atmosphere feeling.

So, moderate brightness + appropriate light and shade contrast, it is the more ideal illume means in illume that occupy the home.

Q3: Power selection of light and dark contrast cable spotlights

It is easy to draw conclusions based on the illumination and contrast of the home environment.

The daily activity illuminance of indoor lighting is 100lx, so the illuminance of the spotlights in the smooth surface should be about 500lx more appropriate, so that it can meet the focus of lighting, but also as far as possible to make people feel comfortable.

Led lighting coffee table lighting

In those who do not have advocate light to decorate, the upper part of tea table is used to shoot the light already is normal, it is the simulation diagram of lighting of sitting room tea table below, shoot the light to distance tea table surface height is 2.2m, be close to actual use scene quite.

The simulated lamps are two 075E-9W-24 ° lamps of Seton. The actual luminous flux of a single lamp is about 780lm, and the total power is 18W.

Below is the simulated illumination:

Graph: lamp acts the role of illuminant madman is abated

If the ambient brightness is about 100lx, the key lighting area is 500+lx, which conforms to the light and shade contrast of about 4, which can not only achieve the effect of outstanding lighting, but also meet the standard of high-brightness operation, but also have good comfort.

Therefore, to install spotlights above the coffee table, the total power is more appropriate in 15-18W, between the lights according to the size of the coffee table to control the distance, if it is a small round few, a 9-10 watts is enough.

The luminous efficiency of conventional lamps is 70-80lm, which will be affected by the material and space reflective rate.

But our lighting scene is always changing, and the illumination of many basic lighting will exceed the standard, the better solution is to use intelligent lamps and lanterns that can adjust brightness.

Adjust to be equal to about 4 light and dark contrast according to use habit, can adjust ambient light, also can adjust shoot light source.

Led illuminates the wall to paint the scene

Since the probability of single illumination is much greater than that of tea table illumination, the power control of wall illumination is more important. The ceiling illumination in the following figure is about 40cm away from the wall, which is close to the actual use scene.

Graph: lamp acts the role of illuminant madman is abated

The simulated lamp is 075E-9W-24 ° of Seton, and the actual luminous flux of a single lamp is about 780lm.

Although such Angle illuminates a picture is not very scientific, but be decorated with dimensional hold back, a lot of owners also have to use such illuminate Angle.

Because the distance of lamps and lanterns gets light object quite close, the center of light spot is the strongest illuminance achieves 1600lx much, this exceeded the normal illuminance of household illume several times.

If the ambient illumination is based on 100lx, the contrast of light and shade reaches 15, which is already in the category of glare, so it is easy to make us feel uncomfortable. If you want to open a single shot light, basic hopeless.

The following is a true feedback from an acquaintance that reading on the sofa with the desk lamp on is a headache.

The following figure shows another kind of simulated illuminance of lamps, with a 5W spotlight at the same distance, about 380lm light flux, which is also 24° reflector spotlight.

The secondary light spot is not so obvious, and the central light intensity of the simulation is 800lx, which alleviates the uncomfortable problem caused by strong light.

Therefore, the lamp is not the more expensive the better, nor is it the brighter the better, everything needs to have degrees, in the article before I mentioned no more than dozens of times on the wall of the spotlight is not more than 7W, because in conventional commercial housing, 7W spotlights with arbitrary Angle irradiation wall can have enough illumination, fully enough. If you like soft ambient light 3-5W is enough.

Don’t listen to the lightman’s whiff of high power.

It a: the unit price of high-power lamps and lanterns is high, profit is high.

Second: afraid of not bright enough, you want to find him trouble, if too bright anyway you do not understand.

All those who want to make your living room installed with 4 60W grating spotlights will be shielded, do not ask why.

Wall lamps in public areas can use Seton 2310S2 generation or 2322-4W/6W, do not care too much about the beam Angle, in home decoration, wall lighting 24° and 30° can be basically universal.

Use of LED spotlights in bedrooms

No matter in the head of the bed/bed end wall, just above the bed, the purpose of using spotlights is to add three-dimensional atmosphere of the space, so the surrounding light environment is much darker than the public space.

Moreover, the bedroom is not the place that others visit stay, also did not see to shoot the lamp when, must open all lamps and lanterns.

As I have mentioned several times in previous articles, spotlights in bedrooms do not exceed 5W at most. The total luminous flux of spotlights in the following figure is about 260lm.

If you use spotlights in low light, I think this brightness is more appropriate. Although single open shoot the light also won’t feel afflictive, suggest a bedroom chooses 3-4W or so shoot the light, control really bad, can use dimmer shoot the light.

If have high brightness to use lamp demand, can open lamp of the head of a bed, day flower lamp is taken or absorb dome light, shoot the light is not used to illuminate whole space originally, also do not ask me again so, how many square bedroom uses how many watts shoot the light such problem. Instead, install a dimmer ceiling lamp.

Led lighting is used for spotlights above desk

As mentioned in the previous article, the top of the desk is the interference zone of the lamp, so don’t count on spotlights to illuminate your desk. Desk or study experience better illume is to have soft light to offer environment illume, mesa lamps and lanterns offers functional illume, still be the problem of contrast of light and shade after all.

Led lighting for spotlights used in kitchen washbasins

Washing basin needs key lighting, and a lot of dish basin design is by the window, so can not install the ceiling lamp, you can design a spot lamp above the dish basin, the power of this lamp can be slightly larger to 7-9W, because the overall illumination of the kitchen is on the high side, if the spot lamp power is too small, subjective feeling will not be bright enough.

But it should be noted that the spotlights should not be installed on the top of the dish basin as far as possible, because when we are working, the subconscious body will lean forward, and the big head will block the beam of the spotlights.

The devil style

To avoid shadow shade, the width of work station face is more 60cm, can shoot the lamp to metope move 10cm or so, perhaps Angle adjusts a bit to metope.

Use of spotlights in led lighting toilets

Fine solution looks to the following article please, say emphatically to step down the light of room of basin, shower, bath crock.

Whole house lighting – kitchen, bathroom lamps and lanterns layout guide

Of stage basin, bath crock shoot the lamp had better be controlled alone, because these two lamps have certain interference sex.

Stage basin shoots the main function of the lamp is to let stage basin more beautiful, with the illume of clean stage basin. When dressing, the light under the spotlight is easy to form contour shadow on the face, which has certain side effects on the face lighting.

Bath crock shoots the main function of the light is the functional lighting of clean bath crock, not be used when bubble bath, you lie lie when bath crock, any comfortable posture is inside glare scope, do not go superstitious what depth prevents glare, everything is to do not have what to use however. Now that you enjoy the bath, why not wear a light belt?

Of shower room shoot the lamp to want to be far from the top that the flower asperses gush, otherwise lamplight is aspersed in the top gush completely.

Power 5-7W, pay attention to buy waterproof lamps and lanterns.

Led lighting see cabinet, see the wall with spotlights

No matter be ark of shoe ark, TV ark, eat side ark, chest, white wall, adornment wall, a lot of people like to use shoot the lamp to illuminate, might as well ask oneself first before using shoot the lamp, what this cabinet has is worth to illuminate, or that sentence, the key too much does not feel the existence of the key instead.

For example, if the only boss in the company wore floral shirts, you could recognize him instantly. If the whole company wore the same clothes, would you still instinctively recognize him?

If the porch that illumination is insufficient, still be worth to install a shoot the lamp, how can your leather shoes brush otherwise oily shine bright?

Of course, everyone’s understanding of lighting is different, there is no right or wrong, as long as you like it.

Led lighting color temperature selection

It is totally subjective aesthetic, but it is recommended to unify as far as possible, choose between 2700-4000K, really can not choose to buy intelligent lamps and lanterns, this is the most brain-free approach.
