What need to be paid attention to when installing LED tube light
09.09.2013.What need to be paid attention to when installing LED tube light? LED is current source, the rectifier and starter is generally not needed; the inner of the LED tube light T8 is large enough, the constant current source can be installed inside the tube. During installation, the original rectifier, starter can be removed for unused, the lamp can be directly installed. Also, the LED tube light installed is a directional lamp. The opposite direction, the lamp is not lit. The electrical expert are considering adding some conversion circuit, so even if in the case of the lamp installed backwards, the lamp also work.
LED tube
Pay attention to the voltage when installing, although there are wide voltage adaptability for the LED tube , it both can work at AC 85V – AC 245V. But voltage is too high or too low for long tine, which will affect the power factor of the constant current source, that is will cause a slight impact on energy efficiency. It would also impact on the life of the constant current source. Therefore, the LED tubes whose voltage is appropriate should generally be chosen. Such as: the electricity is 110V, the LED tubes specially designed for 110V should be used.
Another that should be noted is heat dissipation, LED tube light is equipped with the aluminum heat housing, under normal circumstances, the heat is not a problem. However, if used in a place where the dusty is heavy, the dust shall be regularly removed to prevent dust covering the radiator, result in affecting the cooling.
The waterproof is also very important, because the LED tube light is made by the upper and lower two parts: the upper part is the aluminum radiator, the lower part is the diffuser, there are gaps in the joints, therefore, fumes, water vapor must be prevented from entering. If you used wherever the fumes, vapor is heavier, preferably with a protective cover. General protective cover on it.
One last thing is the anti-vibration, LED tube light has a strong anti-shock capability. Long as not the violent impact, which usually does not cause damage. But it may makes certain effects on the soft board. The traditional fluorescent lamp is made of glass, and the inner is almost vacuum, vibration could cause an explosion, with particular attention to vibration.
Nowadays,the LED flood lamp and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lamp is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED floodlight so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood lamp and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.

What’t the LED lighting requirements for low-voltage driver chip
28.08.2013.LED lighting requirements for low-voltage driver chip
1.The input voltage range of the nominal DC of the driver chip should satisfy 8 ~ 40V, which is to cover a wider application needs. Pressure capacity is preferably greater than 45V. When the input is AC 12V or 24V, the output voltage of the simple bridge rectifier will fluctuate with the grid voltage, especially when the voltage is high, the output DC voltage will be high. If there is not wide input voltage range for the driver IC, which tends to be
breakdown when the grid voltage rises, thereby burning the LED light source.
2.the nominal output current of the driver chips required is greater than 1.2 ~ 1.5A. For the LED light source used for lighting, the nominal operating current of 1W LED light source is 350mA, 3W LED light source nominal operating current is 700mA. Power LED light source needs more current, the LED lighting driver IC selected must have enough current output, the driving IC must also be operated at the optimum working area that is 70 to 90% of the full load output when the product is designed. There is poor heat dissipation when the driver IC is used in the small spaces at the full-load output current, which easily lead to fatigue and early failure.
3.the output current of the driver chip must be kept constant, so to stabilize the LED light, no flash. When the Same batch driver chip is used under the same conditions, the output current should be as consistent as possible, which is discrete to be small, so that ensure the effectiveness and orderliness on the high-volume automated production line. For the drive chip whose output current has certain discrete, required the sub-file selection before the factory or production line, adjust the size of the resistor set by the current on the PCB, so that LED constant current driver of LED lamps board produced is consistent with the emission luminance of the similar light source in order to maintain the consistency of the final product.
4. the package of the driver chip should facilitate rapid cooling of the die of the driver chip, such as the die is directly bind on the copper, and there is a direct extension of the pin outside of the package, in order to that the copper foil directly soldered on the PCB rapidly transfer the heat. If the chip that is similar to the 4X4mm through 300 ~ 1,000 mA current for long time, the power consumption and heat is inevitably generated, therefore, the physical and thermal structure of the chip itself is also very important.
5. driver chip anti-EMI, noise and high pressure capability is also related to that whether the entire LED lighting products can pass CE, UL certification, so the advanced topology structure and high-pressure production process should be used when the driver chip is designed.
6.driver chip’s own power requirements is less than 0.5W, the switching frequency is greater than 120Hz, in order to avoid visible flicker produced by the frequency interference.
In short, LED driver chip urge the green lighting to the development of innovative design. LED lighting without driver chip, requiring multi-functional LED light source driver IC. If the power supply that is less than 36V AC is used for the LED lamps, the non-isolated power supply can be considered; if the choice is 220V and 100V AC power, you should consider the isolating power supply. For the AC 100 ~ 220V drive chip directly used, because the application excessively depends on the volume demanding, there is higher demand, the greater difficulty on the technically, the countries are currently making efforts to develop. The Massive demand for LED lighting market gives the chances of success to all the IC design company again, if rapid transformation and pushing the product as early as possible, then there is a lot chances to win.
