How to choose lights for the living room, study, bedroom, toilet and dining room

Generally speaking, it is appropriate to use solemn and bright chandeliers or ceiling lamps in the living room. If the room is high, it is advisable to use an incandescent chandelier or a larger round chandelier to make the living room appear transparent. However, it is not advisable to use chandeliers with all downward light distribution. Instead, the upper space should also have a certain brightness to reduce the brightness difference between the upper and lower spaces. If the room is low, you can use a ceiling lamp and a floor lamp to make the living room appear bright and elegant, with a sense of the times. The shape and color of the lamps should be coordinated with the furniture in the living room

The lighting in the study should be bright and soft, and desk lamps with incandescent bulbs are more suitable. The desk lamp should adapt to the nature of work and study needs. It is advisable to choose a direct desk lamp with a reflector and a lower opening, that is, a work desk lamp or a writing desk lamp. The light sources of desk lamps are commonly used incandescent lamps and fluorescent lamps. A small spotlight can be installed in the bookcase. This kind of lighting can not only help identify the title of the book, but also maintain the temperature and prevent the books from getting wet and rotting.

The bedroom should be equipped with several kinds of lights, such as ceiling lamps, table lamps, floor lamps, bedside lamps, etc., which should be able to be adjusted and mixed at will to create a warm and atmospheric atmosphere. Wall lamps and floor lamps can be used to replace the ceiling lamp in the center of the room. Wall lamps should use diffuse material lampshades with low surface brightness, which can make the bedroom appear soft and conducive to rest. You can also install a hanging main lamp at an appropriate location in the room and a wall lamp above the bed, and these lights should be controlled separately.

The dining table in the restaurant requires horizontal illumination, so it is advisable to choose a lamp with strong downward direct illumination or a pull-down lamp so that the pull-down height is 600 mm to 700 mm above the table. The position of the lamp is generally Right above the dining table. The lampshade should be made of glass, plastic or metal with a smooth surface so that it can be wiped at any time. Floor lamps can also be used for lighting, and warm-colored wall lamps can be appropriately configured on nearby walls. This will make the atmosphere more lively when entertaining guests and increase appetite.

Ceiling lamps are generally used in kitchens, bathrooms and corridors, because these places require low lighting brightness, high water vapor, and dust. Ceiling lamps are easy to clean and help protect the bulbs. Lamps in the kitchen should be installed in a place where they can avoid steam and smoke. Glass or enamel lampshades should be used, which are easy to scrub and are corrosion-resistant. The bathroom should use bright and soft lamps, and the lamps should be moisture-proof and not easy to rust.

Tips for selecting lamps

In the process of selecting lamps, you must understand these selection prerequisites.

The first thing is safety. When choosing lamps, you cannot blindly be greedy for cheap, but you must first look at their quality and check whether the warranty and certificates are complete. Sometimes the most expensive is not necessarily the best, but too cheap is definitely not good. Many cheap lamps are of poor quality and often have numerous hidden dangers. Once a fire breaks out, the consequences will be disastrous.

Secondly, when choosing lighting, we should pay attention to the consistency of style. The color, shape and style of the lamps must be commensurate with the style of the interior decoration and furniture and echo each other. Flashy lighting is not the icing on the cake, but superfluous. When choosing the color of lamps, in addition to matching the indoor color tone, you can also choose according to your personal preferences. Especially the color of the lampshade plays a big role in the atmosphere. The size, type and number of lamps should be coordinated with the size, total area, indoor height and other conditions of the living room.

In addition, since there are endless styles of lighting fixtures nowadays, before buying lighting fixtures, you’d better understand the development trends of modern lighting fixtures to avoid the fate of obsolete the newly purchased lighting fixtures. Moreover, from the perspective of power saving, more energy-saving light sources can be installed.

Be careful when buying lamps. Lighting is mainly made of glass products, which are fragile and will inevitably be scratched or damaged after long-distance transportation. Since lighting fixtures are usually hung in prominent locations in the home, even minor damage will affect their effectiveness.

Finally, lighting expenditure generally accounts for about 10% of the entire decoration expenditure. Therefore, which grade of lighting to purchase should be decided according to your own financial situation and act within your capabilities.

Prevent light pollution

Some families like to install lights of various colors and styles in the room when decorating.

As everyone knows, in addition to being very harmful to people's vision, colorful lights can also interfere with the functions of higher-level nerves in the brain center.

Especially in the study room, you must choose a lamp with stable brightness. Compared with natural light, the light emitted by ordinary light bulbs is obviously redder in color, which reduces the resolution ability of the human eye. Therefore, if you want to see the fonts in the book clearly, you must move your eyes very close. Although the light emitted by ordinary fluorescent lamps is white, because it is directly lit by 50 Hz alternating current, the brightness of the fluorescent lamp will constantly change. This is the stroboscopic phenomenon of the fluorescent lamp. Studying under constantly flickering fluorescent lamps for a long time will also make your eyes tired.

There is now a new type of eye protection lamp, which is a frequency-free flash fluorescent lamp developed from the lighting source of color LCD monitors. It can emit white light with stable brightness, no flicker, and is very similar to natural light. It is in line with Chinese standards. It is an ideal light source for primary school students to read under the lamp for a long time.

Tips for installing lights

When installing lamps, if you install a sub-control switch, you can save a lot of trouble. Because if there is only one main switch and several lights are turned on and off at the same time, you cannot choose the brightness of the light, which will also waste electricity. However, installing a sub-control switch can choose how many lights to turn on at any time as needed.

If there is an aisle at the entrance of the house, it is best to install a switch at the end of the aisle so that you can turn off the power directly after entering the door without having to go back to the door to turn off the lights.

Lighting is the most charming flirt in the room. Different shapes, colors, materials, and sizes can create different light and shadow effects for different rooms and show different room expressions. Nowadays, facing all kinds of lamps and lanterns in various shapes on the market, do you feel a little dazzled? In fact, when purchasing lamps, you mainly have to consider the following three aspects:

First of all, you should choose the style of lamps according to your actual needs and personal preferences. For example, if you pay attention to the practicality of the lamp, you should choose ceiling lamps or floor lamps with dark colors such as black and crimson. If you pay attention to decoration and pursue modern style, you can choose lively lighting. If you like lamps with ethnic characteristics, you can choose sculpture craft floor lamps.

Secondly, the color of the lamps should be coordinated with the decoration style of the home environment. The layout of the lighting in the room must take into account the style of the furniture in the room, the color of the walls, and the color of the household appliances. Otherwise, the lighting will be inconsistent with the overall tone of the room, which will be self-defeating. For example, if the indoor wallpaper is light-colored, warm-toned incandescent lamps should be used as the light source, so as to create a bright and soft light environment.

Finally, the size of the lamps should be configured based on the indoor area, the amount of furniture, and the corresponding size. For example, a small living room of less than 12 square meters should use ceiling lamps or wall lamps with a diameter of less than 200 mm. The number and size of lamps should be appropriate to avoid appearing too crowded. In a living room of about 15 square meters, a ceiling lamp or a multi-forked chandelier with a diameter of about 300 mm should be used. The maximum diameter of the lamp should not exceed 400 mm. Installing spotlights or wall lamps on both sides of the mural will have a better effect.

In home life, lamps can be divided into architectural lamps and decorative lamps according to different functions. According to reports, architectural lighting should be integrated with the building structure, such as downlights, wall lamps, ceiling lights, recessed ceiling lights, etc. Although these lamps have a variety of styles to choose from, they are relatively single in functionality. Therefore, before home decoration, It is necessary to fully consider the actual functional effects of each lamp after decoration, and do not pay too much attention to style and ignore practicality.

The choice of decorative lamps is relatively casual. Currently, there are a dazzling array of decorative lamps on the market with a complete range of styles. When decorating homes, different families can match them according to their own decoration styles. For example, many families now like crystal lamps, Japanese-style lamps, American-style lamps, etc. In addition, there are also some special-shaped lamps to choose from. From the lighting effect point of view, decorative lamps are mainly used for decoration. Therefore, although some lamps are very beautiful, their functionality is relatively poor. You must consider the use function when choosing.

Light source: It is difficult to have both life and light efficiency

According to the light source classification, there are four types of lights that are more common in daily life: incandescent lamps, energy-saving lamps, metal halide lamps, and LED lamps ( light emitting diode). Each of these lights has pros and cons when used, and it is necessary to fully understand the performance of each type of light.

Incandescent lamps

The biggest disadvantage of incandescent lamps is their short life. The use time is generally between 3000-4000 hours. Some poor quality incandescent lamps can only be used for 1500 hours. However, the color rendering of incandescent lamps is very high, reaching 100, which means that the true colors of objects can be fully displayed. The illumination of incandescent lamps is between 2700K-2800K, and the color is relatively soft. According to their characteristics, incandescent lamps in homes are often used in dining rooms, bedrooms and other spaces, and the colors look more comfortable.

Energy-saving lamps

Energy-saving lamps are popular for their energy saving. A 9-watt energy-saving lamp is equivalent to a 40-watt incandescent lamp. The life of energy-saving lamps is also relatively long, generally 8,000-10,000 hours. The color rendering of energy-saving lamps is around 80, and some products can reach over 85, and the color rendering is also relatively high.

The illumination range of energy-saving lamps is between 2700K-6500K, so energy-saving lamps have two light colors, yellow light and white light, to choose from. Most people psychologically think that yellow light is warmer and white light is colder. Nowadays, many five-star hotels like to use energy-saving lamps with yellow warm light, and the effect is also very good.

High-quality energy-saving lamps use real three-primary color rare earth phosphors to ensure long life and maintain high brightness. After normal use of energy-saving lamps for a period of time, the lamps will dim, mainly due to the loss of phosphors, which is technically called light attenuation. Some higher-quality energy-saving lamps have invented constant-brightness technology, which can keep the lamp in optimal working condition for a long time. After 2,000 hours of use, the light decay will be less than 10.

Metal halide lamp

Metal halide lamp is actually a type of incandescent lamp, and its lifespan is not very long. It is generally between 3000-4000 hours and will not exceed 6000 hours. The illumination of metal halide lamps is between 2700K-3250K. This kind of lamp can be used for accent lighting. For example, in order to highlight the decorative paintings on the wall, indoor ornaments, etc., it can be illuminated with a cold light cup. This white light can be changed according to different home decoration styles and is consistent with fashion.

LED lights

This kind of light is called light-emitting diode and is a new technology. The white light LED lights currently on the market have better performance, but the current LED lights still need to be technically improved. One is that the light efficiency is relatively low, and the other is that the color will be missing. Among the seven bands of red, orange, yellow, green, cyan, blue, and violet, the blue and green bands of LED lights are relatively small, so when displaying the color of things, there will be Experts predict that if LED lights can solve these two problems well, they may replace other lights in the future, because in theory, the life of LED lights is unlimited.

Tips for choosing lamps

Lamps are relatively personalized electrical appliances. As long as you like them, there is basically no rule in choosing them. However, many people now choose professional designers for home decoration design. After completion, it is best to choose lamps and light source types according to the designer's requirements, so that they can better match the home decoration style. After all, designers are professionals.

When choosing the light source of the lamp, you should pay attention to people's psychological feelings. Do not choose too much white light. Using some soft yellow light will make people feel comfortable at home, and the color temperature should be uniform.

Nowadays, many people use light troughs when decorating. In fact, some families will not use them for a long time after moving in. Don’t just follow the trend of decoration, but consider the actual needs.

When choosing lamps, be sure not to be cheap. No matter how small a lamp is, it is still an electrical appliance. In addition to greatly reducing performance, lamps of poor quality may also have hidden dangers in terms of safety.

In order to better save energy, lights should be distinguished by function: general lighting and accent lighting. General illumination can be used for general lighting, but accent lighting should be used for spaces such as artworks and entrances. This will be more reasonable in terms of functionality. Use the lamps in whichever space is used. In addition to saving energy, it can also add indoor space. Sense of change.

Relevant knowledge

Color rendering: refers to the restoration characteristics of light on objects. It has good color rendering and can make the color of objects under light closer to the color under noon sunlight. , which can best reflect the original characteristics of things. The higher the color rendering, the better it can show the original features of things.

Illumination: refers to the brightness of light shining on an object. For example, the illumination range of energy-saving lamps is between 2700K-6500K. The higher the illumination, the brighter the light. 2700k is generally warm light, yellow in color, and relatively soft. ; 6500K is generally cold light and white in color.

Light decay: It is one of the important standards to measure the quality of energy-saving lamps. High-quality energy-saving lamps can ensure the minimum light decay during use.

When you choose a lamp for a children's room, the safety of the lamp itself is the first priority. In addition, it is also important whether the lamp itself is environmentally friendly, has a cute shape, and is in line with children's psychology. In terms of light sources, because children are in the developmental stage, bright lights and high color rendering are very important. Tri-primary color fluorescent lamps are a very ideal choice. They are a new generation of fluorescent lamps that use tri-primary color phosphors. The characteristic is that the luminous efficiency is ordinary 1.4 times that of fluorescent lamps, and the color rendering is 1.2 times that of ordinary fluorescent lamps. Therefore, the three primary color light sources are brighter and display colors more truly and naturally, which is beneficial to children's vision.

1. Selection of lamps

1. Style of lamps

1) First of all, you must buy lamps according to your own different styles. For example, in a modern style, it is suitable to choose some lamps that are a combination of stainless steel and frosted glass. For traditional European and American styles, it is suitable to choose lamps with rococo lines and metallic powder.

2) When possible, choose the same design style for the lighting fixtures in the living room, dining room and bedroom. According to the author's experience, this is possible. Another option is to keep the same style for the living room and dining room, while using another style for the lighting fixtures in the bedroom.

3) For toilet and kitchen lights, waterproof ceiling lights can be used. Generally, there is no need to pay too much attention to style, and the most important thing is practicality.

2. Types of light bulbs

Currently household light bulbs are mainly divided into two types: incandescent lamps and energy-saving lamps. Incandescent lamps operate on the principle of conductive heating of tungsten or other metal wires, and the light color is yellow (sun color). Energy-saving lamps operate on the principle of gas discharge. Their technical name is self-ballasted fluorescent lamps. In addition to white (cold light), there are also yellow (warm light) lamps. Generally speaking, under the same wattage, an energy-saving lamp saves 80% of energy than an incandescent lamp, has an average lifespan of 8 times longer, and only 20% of heat radiation. In non-strict terms, a 5-watt energy-saving lamp can be regarded as equal to a 25-watt incandescent lamp, a 7-watt energy-saving lamp is approximately equal to 40 watts, and a 9-watt energy-saving lamp is approximately equal to 60 watts.

However, some products on the market are currently on the high side and of poor quality. If chosen improperly, problems often arise in saving energy but not money.

Another thing to note is that general energy-saving lamps cannot be dimmed, so you can only use ordinary switches. Never use clock-type dimmer switches to control energy-saving lamps. However, it is reported that it has been developed abroad.

3. Purchase of lamps

The purchase of lamps is very laborious. Before purchasing, you must fully warm up your neck and follow the instructions we learned when we were young. The radio gymnastics method is to turn your head. Otherwise, you will be in a lot of trouble when you come back after buying the lamp. When buying lamps, you should look at more, and it is best to choose a professional market for lamps. Many stores only sell styles from specific manufacturers, so looking around is the only way. In the professional lighting market, the styles are concentrated, so you can save time, effort and energy, and the prices are also comparative.

Two. Installation

The most basic requirement for the installation of lighting fixtures is that they must be secure.

When installing wall lamps, bedside lamps, table lamps, floor lamps, mirror headlights and other lamps indoors, if the height is less than 24m or less, the metal shell of the lamps should be grounded to ensure safety.

When installing short-foot lamp holders in bathrooms and kitchens, it is advisable to use porcelain screw-top short-foot lamp holders. The wiring and phase wire (switch wire) of the screw lamp holder should be connected to the center contact terminal, and the neutral wire should be connected to the threaded terminal.

For lamp holders with switches such as table lamps, for safety reasons, there should be no exposed metal parts in the handle at the beginning.

When installing various types of lamps on decorative ceilings, they should be installed according to the requirements of the lamp installation instructions. When the weight of the lamp is greater than 3kg, it should be installed with pre-embedded hooks or fixed supports and hangers directly from the roof with expansion bolts (the lamps cannot be installed with flat ceiling keel brackets). The wires leading from the lamp head box should be protected with hoses to the lamp position to prevent the wires from being exposed in the flat roof.

Concealed wires in suspended ceilings or wall panels must be protected by flame-retardant casings.

Three. Other notes

1. Kitchen lamps should be ceiling lamps with covers. There is also a recessed light panel with a glass cover on the market (similar to the kind found in office buildings).

2. Bathroom lamps

Bathroom lamps are similar to kitchen lamps. They are required to be anti-fog and easy to clean, so ceiling lamps with covers are the best choice. The lighting in the bathroom should be bright and not too dim. For mirror lamps, it is advisable to use incandescent or natural light-colored fluorescent tubes. Under snow-white light, people tend to look pale when looking in the mirror.

3. There are not many lighting requirements for the bedroom, but it should be noted that downward-facing lamps should not be used in the bedroom, but ceiling-illuminated lights should be used. However, if an incandescent lamp is used as the light for the ceiling, the upper surface of the lamp may turn yellow (this is caused by baking).

This limitation can be avoided if the lighting fixture is not on the top, but on the wall.

4. The living room should have the brightest light (whether it is natural lighting or artificial lighting) in the entire room. Of course, this bright spot is not absolute, but relative. Maybe you don’t need very bright light in some practical activities (such as watching TV), but in other daily living activities, bright light is indispensable.

4. Installation of special lamps

The special installation area of ??household lamps is mainly the ceiling part. Many people like to install diffuse lights concealed, but not everyone can install them well. . The techniques are:

1. Connect them end to end. Fluorescent lamps should be installed one by one. Since I don’t use diffused lights very often, don’t feel bad.

2. The highest position of the lamp tube is at the same level as the edge of the light trough frame of the ceiling.

3. Small light tubes (fluorescent lamps) can be used in curved areas, not a big one.

4. The colors of the lights can be white, yellow and blue (purple). Never use other colors, especially red and green. The former is simply a pornographic place, and the latter has become a terror zone.
