Now, share some experience that the LED lamp strip driving power
The intelligent LED lamp control is one of the advantages, and the power supply is the key of intelligent control.Intelligent control in LED street and LED tunnel lamp lighting application conditions most mature and the most obvious effect, intelligent control can control in different time, to realize stepless adjustment of lamp power according to the road traffic density, can meet the application requirements, and realize the enormous energy-saving effect, saves a large amount of funds for highway administrative unit. The application in the tunnel lighting can not only saving energy, can also according to the brightness of the situation outside the tunnel automatic adjustment of the tunnel entrance brightness, for the driver to provide a visual transition stage, in order to ensure driving safety.

1, giving up four or more outputs, develop single or two outputs, high current and large current to abandon the development of a small current.The more complex of outputs, the cost solve is very high current interference between the different way, if not solve high failure rate. Further more the total output current is greater, and the current is mainly due to the heat, the voltage itself does not lead directly to heat, heat and electric current is proportional to the square,, that current is increased 2 times than the original , then, the amount of heat will increase 4 times than the original, the original current is increased to 3 times, heat will increase to 9 times than the original. In summary, single or two-output LED light strip power failure rate will be much lower.
2, cooling and protection are the main external factor of a power failure.Not only the power supply may have a heat, lamps will be heat, How reasonable to heat dissipated is a matter of lighting design engineer must consider , must prevent the formation of heat, heat island effect, influence power life. Using separate power program is a good choice.
3, to give up power, super power, select a higher stability of small power supply.Because of the greater the power, the more heat generating by components,, which is also more compact components, is not conducive to heat dissipation, and the temperature is the culprit of a power failure. Furthermore, relatively small power development is more mature, stable and cost has advantages.
In fact, many large power supply are not tested over time and practice, are hastily implemented projects are experimental products, so that the failure of endless. Compared with small power supply for early development, technical solutions are more mature.
