Introduction to lighting principles and methods

Before the maintenance and cleaning of the lamps, we must first understand the purchase of the lamps, not only because the lamps are fragile items, but also because the bulbs will be affected by the service life and need to be purchased more frequently. The necessary purchase method will not bring great difficulties to the subsequent maintenance work.

In the process of purchasing, try to choose the home market that consumers are satisfied with or have after-sales service trust. To shop around, for the same style, the same brand of goods, from the quality, price, service and other aspects of comprehensive consideration. The shape of the lamps is antique, innovative and practical. Large chandeliers, wall lamps, ceiling lamps, etc. are all developed according to the 18th century court lamps, which are suitable for social occasions with large space. Modern lamps with unique shapes, such as various spotlights and bull's-eye lamps, are all innovative lamps. The usual daylight, writing desk lamps, floor lamps, bedside lamps, etc. are all traditional lamps. The shape of these three types of lamps should be pursued as much as possible in the overall selection.

Styles should be selected according to their artistic taste and living conditions. Families with living rooms can use some of the more fashionable lamps in the living room, such as trigeminal chandeliers, floral wall lamps, and multi-section rotating floor lamps. Households with tight housing should not be fitted with too stylish lighting, which will increase the crowding. A room with a height of less than 2.8 meters is not suitable for chandeliers. Only ceiling lamps can be installed to make the room look taller. The color of the luminaire is subject to the color of the entire room. In order not to damage the overall color design of the room, we must pay attention to the lampshade of the lamp, the color of the shell is coordinated with the color of the wall, furniture and curtains.

(1) Purchase on demand

Lighting is the crowning touch of the new home decoration, it must not be sloppy when selecting. Generally speaking, it is advisable to use a dignified and bright chandelier or ceiling lamp in the living room. The lighting of the study should be based on the principle of brightness and softness. It is more suitable to use the lamp of incandescent light bulb. The desk lamp of the desk should be adapted to the nature of the work and the learning needs. It is advisable to use a direct table lamp with a reflector and a lower opening, that is, a work table lamp or a writing table lamp. The light source of the table lamp is usually an incandescent lamp or a fluorescent lamp. A small spotlight can be installed in the bookcase. This kind of lighting can not only help identify the title, but also maintain the temperature to prevent the book from being wet and rot.

There are several kinds of lights in the bedroom, such as ceiling lamps, table lamps, floor lamps, bedside lamps, etc., should be able to adjust and mix at will to create a warm and atmosphere. Wall lamps and floor lamps can be used instead of the ceiling lights in the center of the room. It is advisable to use a diffusing material lampshade with a low surface brightness to make the bedroom look soft and comfortable. It is also possible to install a hanging main lamp in a suitable position in the room, and a wall lamp on the bedside, and these lights are separately controlled.

The dining table of the restaurant requires horizontal illumination, so it is advisable to use a luminaire or a pull-down luminaire that is strongly directed downwards so that it can be pulled down to a height of 600 mm to 700 mm on the table. The position of the luminaire is generally directly above the dining table. The lampshade should be cleaned with a glass, plastic or metal material that is clean and tidy. It can also be illuminated by floor lamps, and warm wall lights can be properly placed on the nearby walls, which will make the atmosphere more enthusiastic and increase appetite.

Ceiling lights are generally used in kitchens, hygiene and aisles, because these places require less illumination, and have large moisture and dust. The ceiling lamps are easy to clean and help protect the bulbs. The lamps in the kitchen should be installed in places where steam and smoke can be avoided. Glass or enamel lampshades should be used to facilitate scrubbing and corrosion resistance. In the bathroom, bright and soft lamps should be used, and the lamps should be protected from moisture and rust.

(2) In the process of selecting lamps, it is necessary to understand such selection criteria.

1 Safety, when choosing a luminaire, you can't be greedy and cheap, but you must first check its quality, check the warranty book, and the certificate is complete. Sometimes the most expensive is not necessarily the best, but it is not good to be too cheap. The quality of many cheap lamps is not enough, and there are always hidden dangers. Once a fire breaks out, the consequences are unimaginable.

2 Pay attention to the consistency of style in lighting selection. The color, shape and style of the lamps must be commensurate with the style of interior decoration and furniture. The flashy lighting is not a icing on the cake, but a superfluous addition. In addition to the color tone of the interior, the choice of the color of the luminaire can of course be purchased according to personal preference. In particular, the color of the lampshade has a great effect on the atmosphere. The size, type and number of lamps should be coordinated with the size of the room, the total area, and the height of the room.

3Because the style of lamps and lanterns is endless, before you buy lighting, you should first understand the development trend of modern lighting, so as to avoid the bad luck of the newly bought lighting. Moreover, from the perspective of power saving, it is possible to install an energy-saving light source.

4 to carefully inspect the goods. The lighting is mainly made of glass, which is fragile. After long-distance transportation, scratches or damage will inevitably occur. Since the lighting is generally hung in a prominent position in the home, even a small damage will affect the use of the effect.

5 lighting expenses generally account for about 10% of the entire renovation expenditure. Therefore, the quality of the lighting to be purchased should be determined according to your own economic situation.

(3) To prevent light pollution

Some homes like to decorate the room with various colors and various styles of lights. As everyone knows, the colorful lights are harmful to people's vision, and they can interfere with the function of the nerves in the brain.

Especially in the study, you must use a lamp with stable brightness. The light emitted by a normal ordinary light bulb is obviously reddish compared with natural light, which makes the resolution of the human eye decrease. Therefore, in order to read the font on the book, the eyes must be close. Although the light emitted by the ordinary gaze light is white, since it is directly lit by 50 Hz alternating current, the brightness of the fluorescent lamp will constantly change, which is the stroboscopic phenomenon of the gaze light. Learning under the fluorescent lights for a long time, the eyes will feel tired.

Now there is a new type of eye-protection lamp, which is a non-frequency flash fluorescent lamp developed from the illumination source of a color liquid crystal display. It can emit brightness, flicker-free, natural light and similar white light, which is suitable for primary and secondary school students under the lamp for a long time. Reading requirements are an ideal source of light.

2. Specific lighting method

When introducing the usual precautions for purchasing lamps, we would like to introduce the specific method of lighting for the commonly used lamps.

(1) Selection of energy-saving lamps

Many consumers choose energy-saving lamps for reference to the power of tungsten filament bulbs that have been used. Most manufacturers will list the power of the product itself and the power of the tungsten light bulb with similar luminosity on the package. For example, the package has a "15 watt to 75 watt" logo, which generally means that the actual power of the lamp is 15 watts, claiming to emit a luminosity similar to a 75 watt tungsten filament bulb. Some products have energy efficiency labels on the packaging. The product meets the safety specifications, the light intensity reaches a certain level, and the average life expectancy exceeds 8000 hours before the label can be issued. Some energy-saving lamps are available in white and yellow. The average person feels that the white light is colder and the yellow light is warmer. To compare the differences between the different colors, you can go to the showroom to appreciate. Users can choose the color of the light that matches the furnishings of the home according to their personal preferences. Some shops provide lamp holders to test the lamp for consumers. Try it before payment to ensure that it is operating normally. The plastic shell of the whole lamp should be selected from high temperature resistant flame retardant molded case. Pay attention to whether the lamp is affected by the uneven thickness of the phosphor coating after the lamp is energized.

(2) Selection of crystal lamps

The crystal lamps that have always been graceful and luxurious are now becoming more and more petite. The big change of crystal lamps depends on the advancement of technology. With the development of fiber optics and diode technology, the shape of crystal lamps will become more compact, lighter and more Suitable for modern furniture style decoration needs.

With the development of crystal cutting technology, the ultra-small, modern lines and dreamy colors of crystal lamps will become a highlight of modern living room space. In the selection of crystal lamps, we must pay attention to the following three points: pay attention to the brand logo, the quality of the different brands of crystal lamps, the price and price will vary greatly. Some famous brands guarantee the quality, in order to prevent being caught by the fish, the brand logo will be engraved on each crystal surface, as long as you carefully identify it at the time of purchase. In addition, you need to be reminded that some unscrupulous manufacturers still do a good job, some imitation crystal lamps can almost match the appearance of some brand-name lighting, however, it is likely to be "golden jade, ruined", such as Install high-quality lamp beads on the outside of the larger crystal lamp or in a conspicuous place, and shoddy the inside or hidden parts of the lighting.

Therefore, when you buy a crystal lamp, you must polish your eyes to pick your heart. The specifications of the pendants are particular, and whether the specifications of the pendants of the crystal lamps are uniform is significant. The reason why the crystal lamp can shine brightly and dazzlingly, showing the gorgeous and noble temperament, all relying on a string of pendants. If the layers of the pendants are different in size, it will affect the overall beauty of the crystal lamp. Show. Some of the holes in the imitation crystal chandelier pendants are not standard, or there are sharp edges, wear, and different sizes, which not only affects the appearance, but also is very easy to crack. If the pendant of the crystal chandelier falls from the ceiling, it will be against the family. Security poses a threat.

Now, the crystal lamps on the market generally start at 1,000 yuan. The origin and purity of the crystal is the main factor causing the price difference. Crystal is actually a kind of glass. It is a kind of purified product, and the price varies according to the level of lead content. Therefore, when you purchase a crystal lamp, you must carefully identify the crystal with good quality through the crispness and transparency of the crystal.
