In recent years, LED tube light market is very active, the manufacturer is mainly divided into three categories: one is the original factory which specializes in led chip package, and then penetrates with homeopathic downstream, while led tube light manufacturers have a little circuit knowledge and understanding of LED power; the second category is the traditional lighting factory entering a new field with some knowledge of the circuit; the third category is brand new factory which made other products or new venture, and some have knowledge of led power while some do not.
Some Aspects for Selecting Led Tube Lights
Why must we choose the constant current? LED semiconductor characteristics determine that it is mainly influenced by the environment. For example, the LED current increases with the increasing of temperature the voltage. If it has always worked exceeding the rated current for a long time, it will greatly shorten the service life of the led lighting tubes. LED constant current is to ensure its constant operating current when the environmental factors such as temperature and voltage change. LED operating voltage: Generally, the recommended LED operating voltage is 3.0-3.5V, and most are working at 3.125V by testing. Power Efficiency: This parameter is particularly important, if the efficiency is low, it means that input power of a large part is converted into heat and comes out; if it is installed inside the tube, it will produce a very high temperature, plus the dissipate heat of our LED light efficiency, it will produce a higher temperature superposition. And the life of the electronic components will be shorten the increase of temperature, so efficiency is the most fundamental factor to decide the life of power factor, and efficiency cannot be too low, otherwise the heat consumed on the power is too much. Dimensions: height is the main factors of limitation, and generally the height of T8 tubes / T10 cannot be too high. T10 pipe cannot be more than 15mm in height. Length can be longer and it is easier to give out heat. LED power is the most important part in LED tube light, and it cannot play a performance, or even normal use with improper selection
Heat Dissipation of Led Tube Lights
LED heat dissipation attracts more and more attention, because LED light failure, or life is directly related to the temperature and the bad heat dissipation brings the short life, therefore we have to take seriously of the problem. Unfortunately, so far the actual the heat dissipation cannot meet the standard requirements. So we have long way to go in this technology.
