Lamps are an indispensable item in modern home lighting, and they are also masters of home atmosphere. There are many types of lamps, and the products on the market are dazzling. So choosing a home fixture is not an easy task. Today, the church owner will help you to understand the idea of â€‹â€‹lighting purchases, and grasp the key points of lighting purchase, so as to choose beautiful and suitable lamps.
Part1: A look at the source of light source lighting needs to know
Depending on the definition of the luminaire, the luminaire is all the components required to secure and protect the light source, except the light source, and the line accessories required to connect to the power supply. It can be seen that the light source is the core of the luminaire, and it is very important to select a suitable light source.
First, the light source introduction
The luminaire source refers to the illuminating device in the luminaire. The light source is the most important and core component of any luminaire. There are also many different light sources, and different light sources have different parameters and corresponding different lighting effects.
In the above table, there are some key parameters of the light source, and the indicators of the relevant parameters of different light sources are different. When purchasing a luminaire source, you need to pay attention to these parameters to be able to select the right and appropriate product.
Second, the choice of light source for household lamps
There are many light sources for lamps, and the light sources for household lamps are currently more common in incandescent lamps, fluorescent lamps, energy-saving lamps and LED lamps. Let's take a look at the characteristics of these four light sources and the applicable space.
1, incandescent lamp
Also known as a light bulb, its working principle is that heat is generated when the current passes through the filament (tungsten wire, melting point reaches 3,000 degrees Celsius), and the spiral filament continuously collects heat, so that the temperature of the filament reaches 2000 degrees Celsius or more, and the filament is in an incandescent state. It shines like the red iron that glows. The higher the temperature of the filament, the brighter the light emitted. Therefore, it is called an incandescent lamp.
Advantages: small light source, a wide variety of lampshade forms; large versatility, multi-color variety, directional, scattering, diffuse and other forms; can be used to enhance the stereoscopic effect of objects, incandescent light is closest to sunlight color.
Disadvantages: Non-environmental protection is the biggest disadvantage. When using incandescent lamps, 95% of the electricity is consumed in heating. Only 5% of the electric energy is truly converted into visible light; the heating temperature is high, the heat evaporates quickly, and the life is long. Short (1000 hours), high infrared content, susceptible to vibration, low color temperature, yellow.
2, fluorescent lights
Also known as fluorescent lamps, the fluorescent tubes contain argon (including krypton or neon) and a few drops of mercury. By the mercury atom of the lamp tube, the ultraviolet light is released by the process of gas discharge, and the visible light is emitted by the fluorescent material on the inner surface of the lamp tube. Different phosphors emit different visible light.
Advantages: Energy saving, about 60% of the energy consumed by fluorescent lamps can be converted into ultraviolet light, and other energy is converted into thermal energy. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of the fluorescent lamp is about 60% x 40% = 24% - about twice that of the same power tungsten filament lamp.
Disadvantages: light decay occurs, fluorescent lamps are less colored than incandescent lamps; flashing lights have a certain impact on vision; in addition, mercury contamination occurs during production and after disposal.
3, energy saving lamp
Also known as a compact fluorescent lamp, the principle of illumination is not significantly different from that of fluorescent lamps. However, the energy-saving lamps are relatively small in size, and the electronic ballast volume used is small, and the stroboscopic phenomenon is alleviated.
Advantages: high luminous efficiency, more than 5 times that of ordinary incandescent lamps, energy saving effect is obvious; long life, about 8 times that of ordinary light bulbs; and small size, easy to use.
Disadvantages: light decay; low color rendering, incandescent and halogen lamps with a color rendering of 100, perfect performance; energy-saving lamps are mostly between 80 and 90, low-color light source not only looks at the color is not beautiful It is also harmful to health and vision.
4, LED lights
Also known as a light-emitting diode, it is a solid-state semiconductor device that converts electricity directly into light. The heart of the LED is a semiconductor wafer consisting of three parts, one is a P-type semiconductor and the other end is an N-type semiconductor, where it is mainly electrons, usually in the middle of a quantum well of 1 to 5 cycles. When a current is applied to the wafer through a wire, electrons and holes are pushed into the vector sub-well. In the quantum well, the electrons recombine with the holes, and then the energy is emitted in the form of photons. This is the principle of LED illumination.
Advantages: LED lamps have many advantages such as small size, low power consumption, long life, non-toxic and environmental protection, etc., originally applied to outdoor decoration, engineering lighting, and now gradually develop into household lighting.
Disadvantages: expensive, need constant current drive, heat dissipation is not easy to light decay.
Summary: The light source is the core of the luminaire. Different light sources have different color temperature and energy saving. Everyone needs to decide according to their own needs and price when purchasing. Next, look at the main factors that need to be considered when purchasing lamps, as well as the spatial applicability.
Part2: Second look at the different lamps and lanterns
In addition to the light source, the luminaire includes a lampshade, a base, various lines, and the like. These constitute the shape of the lamp, the installation and installation position and the shape are different, the lamps can be divided into ceiling lamps, chandeliers, wall lamps, spotlights, floor lamps and other types. Let's take a look at the purchase of these types of lamps.
First, the ceiling lamp purchase needs to know
The ceiling lamp is a kind of lamp that is completely attached to the roof at the time of installation. It is simple and generous, and easy to maintain and clean. Therefore, it is the first choice for many owners and friends.
In addition to paying attention to the quality of the light source when purchasing the ceiling lamp, the second is to look at the lampshade. The lampshade should be selected from materials that are not easily damaged, the material should be uniform, and the light transmittance should be high and the lamp should not be illuminated.
Second, the chandelier purchase needs to know
A chandelier is a luminaire that hangs a luminaire on a ceiling with a pole, chain or tube for overall illumination. It is an advanced decorative illuminator on an indoor ceiling.
When purchasing chandeliers, the first thing is to choose the chandelier according to the height of the room. Under normal circumstances, the installation height of the chandelier should be no less than 2.2 meters from the ground. In addition, it should be selected according to the decoration style of the house, such as European classical style. The family can choose a European candlestick ceiling; modern home-style homes can choose crystal chandeliers or stylish chandeliers; while traditional Chinese-style homes can choose Chinese chandeliers.
Third, the wall lamp purchase needs to know
The wall lamp is generally equipped with a glass lampshade. The light reflected through the wall can make the light soft, and the multiple effects of projecting and smudging the light, showing different styles due to the different materials of the house.
The decorative effect of the wall lamp is generally more obvious than the lighting effect, so when choosing, you should first check the effect of it being installed on the wall before deciding. When choosing a wall light, pay attention to the points. First, choose a protective cover, followed by the quality of the lamp cover and the bracket.
Fourth, spotlights need to know
Spotlights are typical lampless, non-scale lamps. If a row of small spotlights is combined, the light can change into a wonderful pattern, which can be placed around the ceiling or the upper part of the furniture, or placed inside the wall, wall skirt or In the baseboard.
At present, the quality of spotlights on the market is mixed, and it is difficult to distinguish between good and bad by the naked eye. Therefore, it is best to choose brand products for the spotlights and choose a high-quality transformer. Moreover, it is generally not suitable to use too many spotlights indoors.
Five, floor lamp purchase needs to know
Floor lamps are often used as partial lighting, not to mention comprehensiveness, but emphasize the convenience of movement, which is very practical for the creation of a corner atmosphere. If the lighting method of the floor lamp is directly projected downward, it is suitable for reading activities such as reading, and if it is indirect lighting, the overall light change can be adjusted.
When choosing a floor lamp, consider the height of the ceiling. If the ceiling is too low, the light can only be concentrated in a local area, which makes people feel that the light is too bright and not soft enough. At the same time, using the above-mentioned floor-standing floor lamp, the ceiling in the home is preferably white or light, and the ceiling material preferably has a certain reflective effect.
Part3: Three-point space lighting purchase key points
We have already learned the basics of how to choose the light source of the luminaire and the luminaires of different shapes. However, in fact, the luminaires need to understand not only the characteristics of the products, but also their own needs, such as the characteristics of the space and the style of the home. . Then let's take a look at how to choose the luminaire according to the different space requirements of the home.
First, the choice of bathroom lamps
1, should choose incandescent lamps, should not choose energy-saving lamps
The lamps in the bathroom are generally characterized by short-term and frequent use. It is best to choose incandescent lamps instead of energy-saving lamps. The reason is that the incandescent lamp starts up quickly, has a short opening time, and has limited energy consumption. However, in the case of a low temperature room temperature in winter, the light-on time is short, and the brightness is not fully achieved, and the energy-saving advantage is not reflected. In addition, the color temperature of the incandescent lamp is yellow, which can give people a warm feeling, and is suitable for the needs of the bathroom, especially the winter bathroom.
2, should choose ceiling lamps and wall lamps
In terms of luminaire styling, the bathroom fixtures should choose ceiling lamps or wall lamps. The advantages of ceiling lamps in the bathroom are not to mention, and the wall lamps are more suitable for bathroom. The lamps in the wall bathroom should pay attention to the moisture and water resistance of the lamps. The shape of the wall lamp generally avoids the damage of the water vapor to the lamp.
Second, the living room lighting selection
There is no law in the choice of lighting in the living room, which can be selected according to the size and style of the space. If you have a small space, you can choose a main light. If you have a large space, you can use a variety of lamps to create an atmosphere. It should be noted that the living room is the place to meet guests, so the light must be sufficient. Common lighting styles include chandeliers plus downlights or light strips.
Third, bedroom lighting options
The bedroom is a private privacy space for rest, and the softening is the key point of the bedroom lighting, so as to ensure the owner's emotional relaxation. Therefore, the lighting of the bedroom is best based on warm and warm yellow. At the same time, the bed above the bed can be embedded with lighting or wall lamps, or can be embedded in the decorative cabinet to make the interior more romantic and comfortable atmosphere.
Fourth, restaurant lighting options
The choice of restaurant lighting can be selected according to the shape of the dining table. For example, it is suitable to install a chandelier of appropriate height above the square dining table, and it should be equipped with a lampshade. If the dining table is round, in addition to the long chandeliers that can be installed directly above, a concealed downlight can be installed on the ceiling as an auxiliary light source. If you are more interested in the atmosphere of the meal, you can choose a wall lamp with adjustable brightness as a restaurant light.
Five, kitchen lighting options
The kitchen is a place to cook, try not to dress it too fancy, it is best to choose the cabinet with its own lamps. From the perspective of energy saving, do not place too many lamps. Ceiling lights are generally not used because they do not collect light, only astigmatism, so it is not suitable for installation in the kitchen. The light source should be chosen to be warmer than possible, and the light is beautiful.
Six, study lamp selection
The study is an important place for work and study. Therefore, it is necessary to ensure that there is sufficient reasonable reading illumination in the selection of lamps. For those who often write at the desk, it is best to have a desk lamp as a local lighting desk lamp on the desk, which is both professional and space-oriented. It is recommended not to use direct lighting. In addition, it is recommended to place an indirect light source around the ceiling for illumination. Indirect lighting avoids visual glare damage caused by direct light.
Seven, corridor lighting selection
Many families will ignore the lighting in this space. In fact, the choice of corridor lighting is also very elegant. If it is equipped with an exotic shell wall lamp and a sapphire wall lamp, it not only plays a role in auxiliary lighting, but also is a beautiful home accessory. In addition, if the corridor is too long, it is recommended to have natural light on the top, and the matching of the wall lamp lighting must be consistent with the overall style of the family.
