Compared with incandescent lamps, LED lamps have softer lights, more energy-saving and more environmentally friendly. , so it has been vigorously promoted by the country. One of the parts that plays an important role in the headset is the light bar. Different led lights have different types of light bars. T5 light bars and t8 lights are two types that are often seen in the market. The model of the light bar, the following is KFEMS Technology Co., Ltd. to introduce the difference between the t5 light bar and the t8 light bar in detail?    The difference between t5 light bar and t8 size    “T” stands for “tube”, which means tubular, and the numbers behind indicate the diameter of the lamp tube. T8 means there are 8 “t”, one t” is 1/8 inch, one inch is equal to 25.4 mm, then each t” is 25.4+8 -3.175mm. The diameter of the t8 lamp tube is 26mm, the diameter of the t5 lamp tube is 16mm, and so on, the diameter of the t12 lamp tube is (12/8)x25.4=38.1 mm, and the diameter of the t10 lamp tube is (10/8)x25.4=31.8mm. Theoretically, the thinner the lamp tube, the higher the efficiency, that is to say, the more reflection of the same wattage.  The difference between the length of t5 light bar and t8      The average t5 lamp tube is 5cm shorter than the t8 lamp tube (the length is different and the interface is not the same), so we must fully consider the size of the lamp tube when we carry out project renovations. If the lamp panel used the t8 lamp J panel before, it can be replaced directly LED lamp tube t8, if you want to change to t5 lamp tube, you need to add a conversion bracket to install it. If the original lamp panel is a t5 lamp panel, it is not possible to replace it with a t8 lamp tube because it cannot be installed, unless the lamp panel is replaced, but the cost is too high. The difference between t5 light bar and t8 brightness      Because the tube diameter of LED lamp t5 is much smaller than that of t8 and t12 lamps, the elastic collision probability between the inert gas atoms and electrons filled in the lamp tube is higher, and the energy loss is smaller, which is also very beneficial to the improvement of light efficiency. Since the inert gas filled is a unique inert gas mixture, it can not only better protect      Protect the cathode of the lamp tube and help the lamp tube take off, and can properly reduce the charging force of the lamp tube, and further increase the luminous flux output of the lamp tube. Therefore, although the power of the lamp tube is lower, the total luminous flux is not reduced, so the light efficiency of the lamp tube is improved, that is to say, t5 is brighter and more energy-saving than t8.  The difference between t5 light bar and t8 application       Both t5 and t8 lamps have their own uses. T8 lamps are widely used in public areas, schools, factories, hospitals, government agencies, bus advertisements, subway stations, etc. T8 is everywhere and t8 tubes are easy to integrate Power supply, due to the small diameter of t5, it is difficult to directly drive the power supply to traditional lamps      Inside the tube, the power supply can only be built in through integration or the method of directly using the external power supply. In this way, t8 is far better than t5 in terms of replacement demand and the complexity of replacing lamp tubes. But in the field of home decoration, t5 is better than t8, because now the home decoration around the ceiling      A circle of light tubes either use flexible light strips or t5 light tubes, and almost no one uses t8, because the circle of lights around the ceiling only needs to play an auxiliary lighting role.      Conclusion: Through the introduction of the editor above, I believe that everyone has a certain understanding of the difference between the t5 light bar and the t8 light bar. Compared with the t5 light bar, the light of the t8 light bar is more dynamic and bright, and the radiation range is wider, which is suitable for large places, while the t5 light bar is suitable for home use. Compared with the t5 light bar, the t8 light bar It also consumes more power. When you choose, you must fully consider the advantages and disadvantages of the t8 light bar and the t5 light bar.

The color saturation reaches 130% full color, making the light clearer and softer. 2. The response time is short, only 60 nanoseconds, which is especially suitable for the light source of automobile lamps, which has won valuable time for the driver to reduce accidents. 3. Small size and light weight. Using its characteristics, various styles of lamps and lanterns that are thin, light and compact can be designed to provide space for car modeling design. 4. the luminous flux of a single LED is small. At present, the research level of the luminous flux of a single LED can reach 120lm/W, and the product level is less than or equal to 60lm/W, and high-power LEDs often require a large radiator, so the LED light source generally adopts the LED array design method. 5. The luminous efficiency of LED decreases with the increase of temperature. Generally, the chip temperature will fail when the temperature exceeds 120℃. Thermal design must be considered in the process design of lamp assembly design and manufacture. 6. long life, good shock resistance. LEDs are semiconductor components. Unlike incandescent lamps, LEDs have no fragile moving parts such as glass and tungsten wires. The failure is extremely low and maintenance-free. 7. high efficiency, low energy consumption. LED light source can directly generate red, amber and other colors required by automobile lamps without color filtering, without loss, and the power utilization rate is as high as 80%. 8. green lighting source. The LED spectrum has good monochromaticity, no redundant infrared, ultraviolet and other spectrums, no mercury harmful substances, and little heat and radiation. 9. The plane emits light and has strong directionality. It is different from the point light source incandescent lamp, and the viewing angle is less than or equal to 180°. When designing, we must pay attention to and use the LED light source to have a different viewing angle and not be greater than 180°. 10. LEDs are multi-component compound semiconductor components. The characteristic of multi-component compound semiconductor components is that the parameters of its electrical, optical, thermal and mechanical parameters are very discrete. When designing, we must fully consider this feature, and require component production companies to strictly classify and grade components according to the requirements of automotive LED light sources. 11. Energy saving and environmental protection: the energy consumption of LED lamps is 1/20 of that of halogen lamps.  12. Low cost and long life: the life of LED lamps from well-known manufacturers can reach 100,000 hours When it is on, it means that basically your car cannot be driven, and it is still on.  13. High brightness: the brightness is much higher than that of halogen lamps, and there is no pressure as a warning light for brake lights.  14. low Voltage safety: LED, as the earliest component used in electronic products, can be lit with only 12V DC voltage, and there is no need to worry about the voltage of more than 20,000 xenon.  15. Momentary lighting: no If you need a xenon lamp again, it will light up again, ready to use.  16. Small size of a single LED: This is a favorite of designers, and can be assembled into various shapes you like.     KFEMS provides Automotive Lighting LED PCB Assembly services.
