In the decoration of the apartment, the lamps are indispensable. It can be said that the lamps are not present at all of us. With the light of the lamps, we can be active at night. So what lights have you chosen at home? Xiao Bian today to take three common lamps as a research object, characteristics and advantages and disadvantages of different lamps, lamps below to write different types of articles introduced, focusing on the advantages and disadvantages of different types of lamps. If you are interested in this, don't miss it!
I. Introduction of different types of lamps - fluorescent lamps
Also known as a fluorescent lamp, the fluorescent tube contains a gas of argon 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.
1, shortcomings
It will produce light decay, the color rendering of fluorescent lamps is not comparable to incandescent lamps; the lighting has flickering, which has certain influence on vision; in addition, there is mercury pollution in the production process and after use.
2, advantages
Energy-saving, about 70% of the energy consumed by fluorescent lamps can be converted into ultraviolet light, and other energy is converted into heat. Generally, the efficiency of converting ultraviolet light into visible light is about 30%. Therefore, the efficiency of the fluorescent lamp is about 70% × 30% = 21%, which is about twice that of the same power tungsten wire.
Second, the introduction of different types of lamps - energy-saving lamps
Energy-saving lamps are popular for energy saving, and a 13-watt energy-saving lamp is equivalent to a 60-watt incandescent lamp. The life of energy-saving lamps is also relatively long, usually 8500-11500 hours.
1, shortcomings
High-quality energy-saving lamps use true trichromatic rare earth phosphors to ensure long life while maintaining high brightness. After a period of normal use of the energy-saving lamp, the lamp will become dark, mainly because of the loss of the phosphor, which is technically called light decay.
2, advantages
The color rendering of energy-saving lamps is around 85, and some products can reach more than 90, and the color rendering is also relatively high. The illumination range of energy-saving lamps ranges from 3000K to 7000K, so energy-saving lamps are available in both yellow and white light colors. The average person will feel that the yellow light is warmer and the white light is colder.
Third, different types of lamps - incandescent lamps
When the current passes through the filament, heat is generated. The spiral filament continuously collects the heat, so that the temperature of the filament reaches 2000 degrees Celsius or more. When the filament is in an incandescent state, it emits light like the red iron can emit light. The higher the temperature of the filament, the brighter the light emitted.
1, shortcomings
Not environmentally friendly, short life, 97% of the electricity used in incandescent lamps is spent on heating, only 3% of the energy is truly converted into visible light; fast thermal evaporation, short life (3200-4150 hours) ), high infrared components, and susceptible to vibration are its shortcomings. The incandescent lamp has an illumination of between 2850K and 300K, and the color is softer.
2, advantages
The light source is small and has a wide variety of lampshade forms; it has large versatility, many varieties of colors, and has various forms such as orientation, scattering, and diffusion; it can be used to enhance the stereoscopic effect of objects, and the color of incandescent lamps is closest to the color of sunlight.
The above is the introduction of different types of lamps for you to share with you, I hope to help you. If you want to know more about the luminaire, please continue to pay attention to the net.
