The lifespan of LED driving power greatly affects the lifespan of LED lamps, so choosing an LED driving power that meets the lifespan requirements is the key to improving the lifespan of the lighting system.
For the life of the LED driver itself, the performance that affects its life mainly includes three aspects: namely, environmental characteristics, component characteristics and power characteristics, which are specifically manifested in the following aspects:
⑴ the impact of the actual application environment: high humidity environment, high temperature environment, dusty environment, strong magnetic environment, vibration environment will have an impact on the final life of the LED drive power supply.
(2) The influence of the temperature environment of LED lamps: the internal temperature of the lamp is less than 65 degrees, the housing of the lamp is less than 75 degrees, and the temperature of the power supply is less than 60 degrees. Because not only the power supply itself will generate heat, but also the lamps and lanterns. How to dissipate these two heat sources reasonably is a problem that lighting design engineers must consider. It is necessary to prevent excessive concentration of heat, forming a heat island effect, and affecting the life of the power supply.
⑶ The influence of the power supply grid: The voltage input of the unstable grid will have an impact on the components of the LED power supply, thus affecting the service life of the LED driver.
⑷ Influence of insulation and installation: The correct installation and good insulation of the product will enhance the vitality of the LED power supply.
⑸ Effect of electrolytic capacitor: When the internal temperature of the electrolytic capacitor increases, the gasified electrolyte will leak from the sealing part of the electrolytic capacitor. This phenomenon will accelerate as the temperature rises. The speed will be increased by 2 times, which means that its life will also be shortened by 2 times. Therefore, it can be said that the electrolytic capacitor determines the life of the LED drive power supply.
⑹ Influence of switching times: LED drive power supply has a rectifier circuit with capacitor input type inside. When the power supply is connected, a surge current will be generated. This surge current will impact the internal components of the power supply, thus affecting the LED drive power supply. service life.
In short, the beautiful night view of a modern city relies on outdoor LED landscape lighting to reflect the cultural taste of the city. It needs scientific coordination, exquisite planning and perfect design to achieve harmony between people and the environment. At the same time, we must pay attention to various problems in the control system and LED drive power supply during the application process, improve its reliability, so that it can bring a beautiful scenery to the city at night, because landscape lighting is endowed with many positive meanings, radiant and colorful The colorful and colorful spaces not only reveal the vitality and aggressive spirit of the town, but also symbolize the good wishes for the prosperity of the country and the prosperity of the people.
