At present, there are many unique and multi-colored lighting fixtures on the market. The price is also structured. Some modern lighting and luxury imported lighting fixtures can be as high as a few thousand dollars, while the common lighting for working-class workers is several tens of yuan. One hundred yuan can be "finished". The lamp is expensive, expensive in the "skin" Buy lighting, just buy expensive? To understand this issue, we must understand where a lamp or a group of lamps is. In a highly competitive market, prices tend to be reasonable, so some expensive lighting must have reasons to support its price. The expensive lamps are mainly expensive in the "skin" (lamps). The “skin†is expensive, first of all, because it is expensive, for example, some expensive chandeliers, the shade is crystal, and the suspenders are pure steel. These materials are expensive on their own, and the complexity of the processing of these materials makes the prices high, so they are buying. When lighting, especially in some reputable stores, it is best not to judge the value of the lamp by price, because some well-designed lamps, although the price is high, but do not have a flavor after entering the home. To be a rational consumer, it is more important to make consumption judgments from the perspective of whether the value and price are in agreement. Light bulbs, but also to buy expensive The lamp in the home is composed of two parts: light source and lamp. The price of lights is relatively high, and there is relative flexibility. For example, although there is a sense of design of the lamp is good, but because the price is expensive, consumers can reduce their own needs, give up the pursuit of the design, buy a suitable price of ordinary lamps; but for the light source, that is, light bulbs, tubes, Absolutely no elastic buying psychology exists. Because the price of the light source is often determined by the manufacturing process and the quality of the product, some "three no" low-grade goods are best not to touch. The effect of the light source not only restricts the lighting effect in the home, but more importantly, there are still security problems. Therefore, it is recommended that you buy some bulbs and tubes. It is better to choose some brands, although the price of a high-quality bulb can be bought. Several low-grade goods, but because of durability and security, it is still worthwhile. Selecting lighting with a scientific vision At present, the lighting market is extremely rich in variety, modeling is ever-changing, and performance varies widely. The beauty of lamps and lanterns is very important, and colors and beautifully shaped lamps can bring joy to people. As the lighting fixture is an organic component of the entire room decoration, its style, material, and illumination must be consistent with indoor functions and decorative styles, and according to this principle, lighting fixtures should be purchased. Because people's eyes are not fixed, often because of this, if the interior lighting fixture brightness distribution is too large, a short time may give people a brilliant bright sense, a long time will cause visual fatigue, therefore, to According to the use of functions in various parts of the home to buy lighting lamps. In general, the living room needs a friendly and welcoming atmosphere. An effective way to produce this effect is to use traditional ceiling lamps or chandelier. The light spreads evenly and the light is slightly weaker and softer. Bedrooms and dens are places for self-relaxation, leaning on the sofa or lying on the bed, listening to music, reading books, and keeping your eyes closed. What you need is the light that can adjust the brightness; with the different spirits and emotions, the brightness of the control is also Different, should use incandescent bulb light source as far as possible, otherwise it will have adverse effect on human eyes. The lighting atmosphere in the restaurant is very important. A soft and bright light environment that is neither too harsh nor dark will not only give people a good appetite but also a good mood. In the restaurant, the most important light source should obviously be on the table. The shape and size of the table should be mastered beforehand to select lamps. For example, a circle of concealed downlights can be used as an auxiliary light source at the top of a large round dining table or at a long dining table. The parallel installation of two long-line chandelier will make the atmosphere of the restaurant more warm and pleasant.
