Why choose constant current power supply for LED line lights?
LED line lights are decorated on the exterior walls of the building, and can be set in different colors and brightness according to different requirements. Depending on the shape of the building, the shape of the lamp is also different, and the specific shape can be selected. LED line lights have the characteristics of energy saving, which not only decorates our living environment but also saves certain resources. Not only that, it is more environmentally friendly, which is what our modern society advocates.
Regardless of the load change, the circuit that keeps the current of the LED strip light constant is called LED constant current drive. The purpose of using LED constant current drive is to improve the service life and light decay of LED. The selection of the constant current source is based on its efficiency and stability, and the constant current source with high efficiency is selected as much as possible, which can reduce the loss of energy and temperature.
LED line lights are energy-saving products with high driving power efficiency. This is especially important for the structure of the power supply installed in the luminaire. Since the luminous efficiency of the LED decreases with the increase of the LED temperature, the heat dissipation of the LED is very important. The power supply efficiency is high, the power loss is small, and the heat in the lamp is small, which reduces the temperature rise of the lamp and is conducive to delaying the light decay of the LED. If you don't use a constant current source, use a constant voltage source to supply power. When the normal temperature is 20mA, the current will be reduced to 8-10mA, and the brightness will be reduced when it reaches -40 degrees. For 1W high-power LED chips, the situation is the same, and due to the high power, heat dissipation is not easy, and the temperature rise problem is more serious.
