Some of the materials used in lighting features and detailed analysis


【Brief Description】Authentic crystal lamps should be made of K9 crystal material. Due to the value of natural crystal is expensive, and more defects, not suitable for batch sharing, and a serious shortage of resources, crystal lamps on the crystal is now synthetic products, whether imported or domestic, the value of how much is so.

1. Crystal (Quartz Crystal).

Crystal lamps

Authentic crystal lamps should be made of K9 crystal material. Due to the value of natural crystal is expensive, and more defects, not suitable for batch sharing, and a serious shortage of resources, crystal lamps on the crystal is now synthetic products, whether imported or domestic, the value of how much is so. From the chemical composition of crystal is made of glass and part of the metal lead synthesis, when the content of lead in glass up to 24% can be called the meaning of the crystal, the role of lead is to make the glass better light transmission, natural light through the refraction out of the strongest color light.

Crystal lamp texture is generally divided into natural crystal, heavy lead crystal, low lead crystal, crystal glass, etc., now more than 95% of the crystal lamps on the market is crystal glass, and even plastic.

There are even plastic ones, and the money price is much lower than natural and lead crystal. The main metal material of crystal lamp is divided into two kinds of copper and iron, copper price is about 4 to 5 times of iron. Iron, first of all, is cheaper and significantly better than copper in terms of sturdiness and resistance to deformation, so every lamp is made of iron material in the center channel part and the square tube part, even if the lamp is all copper, the disadvantage is that if it is not completely covered by electroplating, then the possibility of rusting is 100%. Copper, expensive, softer material, superior to iron in surface treatment, under normal circumstances its chances of rusting are very small. The same lamp holder, with copper and iron cost difference will be 4 to 5 times.

If you do thick transparent lampshade, the best effect with crystal, the unit price is also relatively high, the glass will be thick bubbles.

2. Soft pottery (Polymer Clay).

Soft pottery lamp

Soft pottery is an artificial low-temperature polymer clay. Also known as "pottery", also known as "barbecue clay". From the appearance of the clay, the small package is extremely similar to Play-Doh, and in the baking before the play also has a lot of close to Play-Doh. Different colors of clay can be aggregated and molded into a variety of different patterns and shapes. Some predict that soft clay will be the most fascinating craft material in the 21st century.

3. Parchment (Parchment)

Parchment Lamp

Parchment lamps sold on the market today are imitation parchment (industry known as parchment), which is a polymer material covered with a film to create the effect. Moreover, in terms of lamps, due to its relatively simple manufacturing process, the basic homogenization, different only the shape and brand differences, which is also for the same style, different brands, but the reason for the large difference.

Because of the parchment paper imported and domestic, therefore, a better brand of parchment lamps and lanterns most of the imported parchment paper, quality than domestic to be better, the price is naturally higher.

Parchment lamp is best to use energy-saving lamps as a light source, if the surface heat of the bulb is relatively high, long will make the parchment aging deformation, and easy to odor, pollution of the environment.

Select parchment lamp five points: ① see how the feel: two quality of parchment, touch the feel is not the same, good touch smooth some, poor touch rougher. ② look at the flexibility of the material: poor quality parchment paper is very brittle, a break can be broken open, and good flexible, not easy to tear and break. ③ look at the lamination to determine the scrub resistance: poor parchment, the lamination is easily uncovered and torn off, so the light is not scrub resistant. And better parchment laminate is more solid, film and the main body is basically one, it is difficult to uncover.

Therefore, it can be washed. ④ Combustibility: parchment can be lit with a lighter, but once away from the source of fire, poor parchment is still burning, and will emit black smoke, while the better will be immediately extinguished. In addition, the poor parchment will smell a little plastic after burning, while the good basic smell does not come out, which reflects the difference in its environmental protection, which is a very important point. ⑤ high temperature resistance, aging resistance: because of the good quality of the parchment lamp has good flame retardant, non-open flame is not easy to burn, so that it has a better anti-aging, which is its long-lasting preservation of new characteristics.

4. glazing (Glass).

Liuli lamp

In ancient China, the name of glass is a narrow term for glass. Nowadays, glaze generally refers to the colored glass works made by adding various oxides. The material of glazing is artificial crystal glass. Its characteristic is that it has a high refractive index to light, so it can present a crystal clear effect, and under the cooperation of light, it can fully express its artistic characteristics. 5.

5. Stainless steel (Stainless Steel).

Stainless steel lamp

Refers to the resistance to air, steam, water and other weakly corrosive media and acid, alkali, salt and other chemical leaching medium corrosion of steel, also known as stainless acid-resistant steel. In practice, often will be resistant to weakly corrosive media corrosion of steel called stainless steel, and will be resistant to chemical media corrosion of steel called acid-resistant steel. Due to the differences in the chemical composition of the two, the former is not necessarily resistant to chemical media corrosion, while the latter are generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. 6.

6. aluminum alloy (Aluminum)

Aluminum lamp

Aluminum alloy still maintains the characteristics of light weight, but the mechanical properties are significantly improved. Using the characteristics of aluminum alloy can be colored after anodic oxidation treatment to make a variety of decorative products. The surface of aluminum alloy plates and profiles can be secondly processed such as anti-corrosion, embossing, painting and printing to make various decorative plates and profiles as decorative materials. The low cost and the fact that the same parts can be produced in large quantities using one processing is one of his characteristics. Its material properties are lightness, ease of processing, and a range of maximum stresses unlike carbon fiber in terms of tolerable strength. In other words, carbon fiber has a high force capacity in certain fiber direction because of its fiber properties.

The force capacity is very strong in a certain direction, but the force capacity in other directions is very poor. In the case of a large part, several layers of carbon fiber may be used, and the part will become like a pancake when the force capacity is exceeded. And aluminum alloy will slowly deform and then damaged after withstanding a certain amount of force.

7. acrylic (Acrylic, PMMA)

Acrylic light

Hong Kong people are mostly called acrylic, is an important thermoplastic developed earlier, with good transparency, chemical stability and weather resistance, easy to dye, easy processing, beautiful appearance.
