Here is Waterproof Led Street Light Supplier talking about Top ten considerations for LED street lights.
If you have any idea about it, welcome to contact us and discuss.
1. The general No Strobe Led Street Light isolated power supply is made into 15W, placed in the LED street lamp power supply tube, the transformer is very large, it is difficult to put it in. Mainly according to the specific circumstances, the isolation can only be 15W, less than 15W, and the price is very expensive. Therefore, the cost performance of isolation is not high, generally non-isolated is more mainstream, the volume can be made smaller, the minimum can be as high as 8 mm, in fact, non-isolated security measures are done, there is no problem. Of course, space can also be used to isolate power.
2. How does the Long Lifetime Led Street Lamps power supply match the lamp bead?
In fact, led street light manufacturers choose one of the best string parallel connection methods, the voltage and current applied to each LED is the same, and the power supply effect can play the best performance.
3. LED street light power efficiency
LED street lamp input power minus output power value, this parameter is especially important, the greater the value, the lower the efficiency, which means that a large part of the input power is converted into heat, if it is installed in the lamp, it will produce a very high Temperature, and the heat generated by one of our LEDs will be superimposed to produce higher temperatures. The life of all electronic components inside our power supply will decrease with the increase of temperature. Therefore, efficiency is the most reliable. The fundamental factor, the efficiency cannot be too low, otherwise, the heat consumed on the power supply is too large. Non-isolated efficiency is higher than isolation, generally more than 80%.
4. LED street light power supply cooling
The main factor of heat dissipation is that the LED street lamp power supply bead can be used to extend life in a hot condition. The LED street lamp manufacturer generally uses an aluminum alloy radiator to facilitate heat dissipation. That is, the LED street light power bead is attached to the aluminum substrate, and the external heat dissipation area is maximized.
5. LED street light source cooling
The main factor of the heat dissipation scheme is that the LED street lamp bead can greatly prolong the service life under the condition of not being heated, and the LED street lamp manufacturer generally uses aluminum alloy, which is more convenient for heat dissipation. That is, the LED street light power bead is attached to the aluminum substrate, and the external heat dissipation area is maximized.
