How to choose 1 as the light source of chandelier; Comparison of advantages and disadvantages of various light sources.
1. Incandescent lamps are equipped with tungsten wires. Luminous efficiency 10 ~ 15 flow/watt, color temperature around 2800, good color rendering. When the rated life is 1000, 220 volts is different from 220 volts. There are two kinds of lamp holders: screw type and bayonet type. Reflective incandescent lamps emit light beams directionally, using light energy. Generally used in windows, exhibition halls and places where spotlight lighting is needed.
2. Tungsten filament of halogen tungsten lamp is installed in the halogen tungsten lamp, and a certain amount of iodine and bromine or their compounds are filled. Tungsten halogen lamp uses the chemical reaction principle of tungsten halogen cycle, which greatly reduces the evaporation of tungsten wire and the blackening of bulb. The luminous efficiency and rated life of tungsten halogen lamps are higher than those of incandescent lamps. Tungsten halogen lamps are often made into small tubes with power of 300 ~ 1000 watts, color temperature of 2800 ~ 2900 kelvin, good color rendering and stable time flux with rated life of about 1500. Mostly used for indoor and outdoor large-area lighting.
3. Fluorescent lamp Fluorescent lamp is also called fluorescent lamp. Different fluorescent substances will emit different visible light. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of fluorescent lamps is about 60% × 40% = 24%, which is about twice that of tungsten lamp with the same power.
4. Energy-saving lamps Energy-saving lamps are also called compact fluorescent lamps (CFL lamps abroad). It has the advantages of high light efficiency, obvious energy-saving effect, long service life, small size and convenient use. Generally speaking, under the same wattage, energy-saving lamps save 80% more energy than incandescent lamps, prolong their average life by 8 times, and radiate only 20%. Under non-strict conditions, a 5-watt energy-saving lamp can be regarded as a 25-watt incandescent lamp, a 40-watt 7-watt energy-saving lamp and a 60-watt 9-watt energy-saving lamp.
5, LED lamp LED lamp is also called light emitting diode, which is a solid-state semiconductor device. LED lamps have many advantages, such as small size, low power consumption, long life, non-toxic and environmental protection, and have gradually developed from outdoor decoration and engineering lighting to home lighting.
How to choose a chandelier
1. When choosing a chandelier, on the one hand, we should consider the height of the room and the indoor environment. The thickness of the chandelier should be less than one third of the major diameter of the chandelier, and the ratio of the clear height of the ceiling of the chandelier to the thickness of the chandelier is 1. On the other hand, we should pay attention to the quality of lamps. First, it depends on the pendant on the lamp, which bears the weight of the whole lamp. The quality of the pendant is very important. Generally speaking, the metal pendants on good quality lamps are mostly thick. Second, it depends on the quality of glass or imitation crystal on the chandelier, and choose a good material from color and brightness.
2, according to the size of the house, choose the right chandelier. Choose a suitable chandelier according to the house. Make sure that the floor is 2.2 meters high from the lower part of the chandelier.
3. According to the decoration style of the house, choose the chandelier that suits the style. If the decoration style of the house is European, choose the chandelier with the corresponding style.
4. Check the original part of the chandelier. Many chandeliers are made of wrought iron, and the products are very conductive, so consumers should pay attention to the safety of chandeliers when buying them.
5. When buying a chandelier, just buy an energy-saving lamp light source or a chandelier. Also, try not to choose a chandelier with an electroplated layer. The chandelier decorated with electroplating layer is easy to fall off by oxidation in daily use, which affects the beauty of the product.
6. Maintenance and cleaning of chandeliers: Generally, beautiful chandeliers are usually complicated in shape and lampshade. If it is a wet and dusty place, lamps are often prone to rust and paint, and lampshades will become dim because of dust. Don't clean the lamps with water, and don't wipe them with a wet rag immediately after turning on the light, because the bulbs are easy to burst when exposed to water at high temperature.

The light source is as important as the human heart, so the choice of the light source of the chandelier must be careful.
At present, there are incandescent lamps, energy-saving lamps and LED lamps on the market, but incandescent lamps and energy-saving lamps are gradually replaced by LED lamps. The reason is that LED lights are more eye-protecting, energy-saving and environmentally friendly.
Pay attention to color rendering when choosing LED light source. Color development refers to the ability of light to restore the color of an object. The more complete the spectrum of the light source, the better the color rendering, and the closer the color of the object is to its original color. Generally, the color rendering of light can be called a high-quality light source when it reaches more than 90Ra, so attention should be paid to CRI≥90RA when selecting light.
Third, the chandelier purchase precautions
1, the height of the chandelier
When buying a chandelier, consider the height of the chandelier. It is suggested that the height of the chandelier should not be less than 2.2 meters, otherwise it will affect daily life and make people feel depressed.
