t4灯管t5灯管区别（T4 tube T5 tube difference）

t4灯管t5灯管区别（T4 tube T5 tube difference） t4灯管t5灯管区别(T4 tube T5 tube difference) Talk about the "T" in the light tube model, and the numbers represent the meaning Do you use fluorescent tubes often? Now commonly used T8, T5, T4 tube, the previous two years are commonly used T10, T12. So what does this "T" mean? What's the difference between T5 and T4? I say, we can be interested in. "T", to put it bluntly, actually represents the diameter of the tube. Every "T" is 1/8 inches. As you all know, an inch equals 25.4 millimeters. Then the diameter of the T8 tube is 25.4mm. The rest of the figures correspond to the following: T12 diameter 38.1 mm T10 diameter 31.8 mm T8 diameter 25.4 mm T5 diameter 16 mm T4 diameter 12.7 mm T3.5 diameter 11.1 mM T2 diameter 6.4 mm Theoretically, the higher the efficiency of a thinner tube, the more luminous the same wattage. In actual use, the light tube is easy to hide, and the occasion is flexible. That is why T5 and T4 tubes are favored by designers But the thinner the tube starts, the more difficult it is, so when the T5 tube is developed, an electronic ballast must be used to start it. In order to save costs, T5 and T4 are used to sell Mini support form, is contained in the ballast micro space support, the efficiency and quality of the ballast is generally not good, should lead to very high efficiency lamp instead of conventional T8 lamp light, the life also slightly discounted. Nevertheless, the temptation of thin tube is still very big, T5, T4 lamp sales volume is more and more big. Specific to T5 and T4 is different, I sum up a few points: 1, different diameter, 16mm VS 13mm this is not nonsense. 2, brightness is different, theoretically T4 should be efficient, but because of the quality of ballast problems, now a lot of T4 are not as bright as T5. 3, life and stability are different, T4 is not as mature as T5, so life is slightly shorter than T5 at present. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * My home is now loaded with T4 tube is not very bright, I think the effect is not good, or T5 light, it is recommended that the T has not installed TXM tube, T5 lamp tube 1. T5 is brighter than T4 2. T5 is better than T4 3. T5 varies in length according to wattage, and is common in most families: A.20W length 64cm 640mm B.30W length 96cm 960mm C.40W length 128cm 1280mm X * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 88 * * * * * * * * * * * * * * * * * * * * * * * Advantages of T5 fluorescent lamp in night light illumination Because the night light is usually illuminated by the window and the glass curtain wall, the lighting effect is achieved. Some buildings, windows, glass curtain walls and glass are darker, and the use of ordinary fluorescent lamps is difficult to achieve better results. Because of the advanced materials and technologies, T5 fluorescent lamp has a luminous efficiency of 98LM/W, much higher than the average 60 LM/W T8 T12 71 LM/W fluorescent lamp. Because of the high luminous efficiency, the T5 fluorescent lamp can solve the problem of light penetration, which can make every building achieve good lighting effect. Shanghai Huaihailu Road Construction Bank building uses T5 fluorescent lamp to solve the problem that it is difficult to achieve better lighting effect because of the darker color of glass curtain wall. In addition, the color index of T5 fluorescent lamp is 82, and that of ordinary fluorescent lamp is 65. The T5 fluorescent lamp can reflect the real features of the building more realistically, and can effectively prevent the improper use of light colors and destroy the architectural style, thereby making the lighting effect more ideal. According to the international IEC standard, the power of conventional T5 fluorescent lamp is designed as 28W, which mainly replaces T12, 40W and T8 36 W fluorescent lamps. As can be seen from the previous table, the illuminance of the T5 fluorescent lamp is 40% higher than that of the T12 fluorescent lamp and 28% higher than the T8 fluorescent lamp under the same lamp power condition. In daily use, because the T5 lamp light effect is high, and the T5 tube electronic ballast power consumption is only about 4 W, power T8, T12 single tube ballast is about 10W, plus T5 new lamps due to small size, can use sophisticated materials, fine processing at the same cost, improve the efficiency of lighting lamps, so the field where the prerequisite to meet the same illumination condition, the number of installed T5 lamps can be respectively than the number of T8, T12 lamp is reduced by 30% and 45%. At present, the domestic light night lighting is widely used double tube fluorescent lamp, in the window and curtain wall glass above arrangement arrangement. We assume that the implementation of a building interior translucent night lighting project needs T5 lamps for 5000 sets, to achieve the same brightness, you need 6900 sets of T8 lamps, T12 lamps 8160 sets. According to the daily light time is 5 hours, 1 yuan per kilowatt hour electricity calculation. The annual operating costs of using T5, T8, and T12 are as follows: 1, "sunshine" T5 fluorescent lamp (28 watts) The total power consumption (tube + electronic ballast): 32 watts The power consumption: 5 x 32 x 2 watt hour support * 365 days * 5000 * 0.001=584000 kWh The total amount of electricity: 584000 x 1=584000 yuan 2, T8 fluorescent lamp (36 watts) The total power consumption (tube + electronic ballast): 46 watts The power consumption: 5 x 46 x 2 watt hour support * 365 days * 6900 * 0.001=1158510 kWh The total amount of electricity: 1158510 x 1=1158510 yuan 3, T12 fluorescent lamp (40 watts): The total power consumption (tube + electronic ballast): 50 watts The power consumption: 5 x 50 x 2 watt hour support * 365 days * 8160 * 0.001=1489200 kWh The total amount of electricity: 1489200 x 1=1489200 yuan 4, save electricity bills every year: "Sunshine" T5 fluorescent lamp saves 574510 yuan more than T8 fluorescent lamp "Sunshine" T5 fluorescent lamp saves 905200 yuan more than T12 fluorescent lamp At the same time, T5 fluorescent lamp design life of 10000 hours, is ordinary T8, T12 two times, the actual use and replacement of the lamp also has a big gap, the overall maintenance cost is low. Small size, light weight, easy installation and maintenance T5 fluorescent lamp tube diameter of 16mm, is T8 of 3/5, T12 2/5. It is easy to design all kinds of new lamps and lanterns. Sunshine has introduced T5 lamps and bracket products, and its volume is much smaller than T8 and T12 lamps. At the same time, the sunlight lamps and lanterns adopt the high performance electronic ballast comprehensively, the lamps and lanterns weight drops obviously, the installation and maintenance are very convenient. In our country, night scene lighting has been gradually paid attention to in recent years, General buildings only consider external lighting in the design and construction, and did not consider the inner light transmission technology. Therefore, at present in the domestic implementation of the project is the most transparent in mount again, this requires the lamps to be low requirements on the environment, can be suitable for different installation and narrow window, and does not affect the curtain rail and the indoor appearance. T5 lamps as small size, light weight, fully meet the above requirements, the sun has developed MX1, MX2, MX3, MD1, MD2, MX5, MX6, MX 7 and corner lamps and other T5 products, in many domestic such projects.
