How to choose LED floodlight
The price of the led floodlight depends on the quality, the quality depends on the heat dissipation and the influence on the heat dissipation in the basic parts such as LED Chips, Power supply and shell. In the market, the power supply of floodlights can be divided into constant current drive and linear drive.
The cost of constant current power supply is much higher than that of linear power supply. Why choose constant current drive? According to the V/A characteristic of the LED chip, the slight change of the input voltage of the power supply will increase the current flowing through the LED chip, which will lead to the increase of the temperature.
In order to prevent the temperature rise caused by power supply, constant current drive is the best solution. In order to keep the current flowing through the LED unchanged, so as to ensure the life and light decay of the LED beads.
