 LED luminous characters have a beautiful day, night bright, energy saving, durable advantages, but also to meet the energy-saving, environmental protection, urban landscaping standards to Liaoyuanzhishi quickly became popular. However, LED light source used in the advertising industry (light word) production, there have been a lot of unsatisfactory issues. A common problem 1, LED life is short: Theory regular manufacturers of LED life is generally about 80,000 hours. And now a lot of light word useless than a year began to frequent replacement of LED modules, to customers and advertising producers have brought a lot of trouble and economic losses. 2, the color decay very quickly: just install a good word luminous color emitted pure bright colors can be used to significantly less than a year dim down. Font becomes red is not red, not green, green is very ugly. 3, uneven color, color clear: on mainly in the production of pure white LED luminous characters larger. When assembling individual modules was not obvious, the whole assembly complete font, the color is evident from the entire map as literal as a white, a blue and a yellow. 4, part of the stroke font, when suddenly a whole is not bright or not bright light: light word after a period of use in part or in whole font elimination began flashing, when the light does not shine until it does not shine. 5, the output power is larger font, energy saving is not obvious. Current, LED fluorescent market is very active, the manufacturer is divided into three categories: one is the original do LED chip factory, homeopathic downstream penetration, much knowledge and understanding of the circuit LED power; the second category is the original do general lighting factory lighting project into a new field of urban lighting projects, some knowledge about the circuit; three are completely new entrants factories, they used to do other products or new business, and some understanding of the LED power supply, and some do not understand . LED power LED lamp is the most important part, improper selection, LED lamp performance can not play, can not even work properly. 1. Why must constant: the characteristics of LED semiconductor larger decisions influenced by the environment. For example, elevated temperature park lighting project, the LED current increases, the voltage increases, the LED current will increase. Long-term than the rated current work, will greatly shorten the life of the LED. And that is when LED constant current and voltage changes in environmental factors such as temperature, to ensure that their operating current constant. 2, LED fluorescent lamp power supply board match: some customers to design the light board, find the power, find it difficult to have a suitable power supply, or too much current, the voltage is too small (as I> 350mA, V <40V); or current is too small, the voltage is too high (eg I180V), resulting in a severe fever, low efficiency led lighting engineering company, or the input voltage range is not enough. In fact, choose a best string and joints, increase in the voltage and current on each LED is the same, but the effect of power able to play the best performance. The best way is to communicate and power supply manufacturers, tailored.
