LED outdoor linear lights adorn the exterior walls of buildings. Outdoor lighting can set different colors and brightness according to different requirements. In short, in malls and cities, we set up different lighting effects to match. Also, depending on the shape of the building, there are requirements for the shape of the lamp It is also different. Specific shapes can be selected. LED linear lights have the characteristics of energy saving, which not only decorates our living environment, but also saves some resources. What's more, it is also more environmentally friendly, which is also advocated by our modern society. A circuit in which the LED current remains constant regardless of load changes is called LED constant current drive.
The purpose of LED constant current drive is to improve the service life and light decay of LED. The choice of constant current source is based on its efficiency and stability, try to choose a constant current source with high efficiency, which can reduce energy loss and temperature. LED is an energy-saving product, and the efficiency of the driving power supply is high. This is especially important for structures where the power supply is installed in the lamp. Due to the luminous efficiency of LEDs in outdoor lighting projects, as the temperature of LEDs increases, it will decrease, so the heat dissipation of LEDs is very important. High power efficiency and low power consumption. It generates a small amount of heat in the lamp, and also reduces the temperature rise of the lamp tube, which is conducive to delaying the light decay of the LED. If the constant voltage source is used instead of the constant current source, it will work at 20mA at room temperature, and when it reaches -40 degrees, the current will be reduced to 8-10ma, and the temperature of the lamp will be reduced. The same is true for 1W high-power LED chips. And because of the high power, it is not easy to dissipate heat, and there is a problem of heating up, so be more careful.
