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, in the home decoration, scientific and rational choice of lamps suitable for their families. Lights expensive, expensive to buy lighting in the "skin" , just buy expensive enough? 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 when buying lights, especially in some reputable stores, it is best not to judge the value of lamps by price, because Some cleverly designed lamps, although they are overpriced, do have some flavor after entering 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 home lights, 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 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.
