LED lights in the current community of large-scale application for the progress of lighting projects played a decisive role, especially LED lights and energy-saving low-carbon aspects of the community has made important contributions to the following we say that in the daily use of the process LED lights should pay attention to 10 matters.
6, isolated / non-isolated
General isolation power supply such as made 15W, on the LED lights in the power supply, the transformer is very large, it is difficult to put into. Mainly to see the spatial structure, depending on the specific circumstances, the isolation can only be done in general 15W, more than 15W very little, and the price is very expensive Therefore, the isolation of the price is not high, generally non-isolated accounted for more mainstream, the volume can be done smaller, the minimum can be high 8 mm, in fact, non-isolated security measures done, there is no problem. Space allows you to do the isolation power supply.
7, LED street lamp power to what can be done with the lamp beads board match?
In fact, choose a best string and parallel way, plus the voltage and current on each LED is the same, and the power of the effect can play the best performance. The best way is to first communicate with the power supply manufacturers, tailor-made. Or self-produced power.
8, LED street lamp power efficiency
Input power minus the output power value, this parameter is particularly important, the greater the value of the lower efficiency, it means that a large part of the input power into heat out; if installed in the lamp will produce a very high temperature , Coupled with a luminous efficiency of our LED than the heat, will be superimposed to produce a higher temperature, and our internal power supply of all electronic parts will increase with the temperature rise and shorten, so that efficiency is to determine the power life of the most The fundamental factor, the efficiency can not be too low, otherwise consumed in the power of the heat is too large. Non-isolated efficiency is higher than the isolation type, generally more than 80% can, but the efficiency of the matching with the light board connection
9, LED lights light source heat
The main factor of the cooling program is LED lights lamp beads in the use of thermal conditions can greatly extend the life, generally with aluminum, easier to heat. That is, LED street lamp power beads posted on the aluminum plate, the external as far as possible to expand the cooling area.
10, LED lights power supply cooling
The main factor is the heat dissipation LED street lamp power beads in the use of thermal conditions can greatly extend the life, generally with aluminum radiator, easier to heat. That is, LED street lamp power beads posted on the aluminum plate, the external as far as possible to expand the cooling area.http://www.yingyaolighting.com/
