What are the factors that affect the life of a plant light source?

Power supply EncyclopediaSanjibao01 Jun 2018
What are the factors that affect the life of a plant light source? The plant light power supply is actually a kind of driving power. What is the life expectancy of the plant light power supply, and what factors are it affected by it? Zhongfu photoelectric plant lamp power supply technicians for everyone to analyze:


LED plant light power


1.Depends on the lamp temperature environment

The temperature environment of the plant lamp power supply in the temperature environment of the lamp will have a certain impact on the life. The internal temperature of the lamp is less than 65 degrees, the lamp housing is less than 75 degrees, and the power supply temperature is less than 60 degrees.

2.Depends on current voltage

The plant light power supply has comprehensive protection features including overvoltage protection, input undervoltage lockout with hysteresis, and multiplier output clamp to limit the maximum peak current of the switch. When designing the power supply of the plant lamp, it is necessary to know the current and voltage characteristics. Due to the different manufacturers of the power supply and the power supply specifications, the life of the plant lamp power supply is shortened, and even when the power is severely burned.

3.Depends on the number of switches

Most power supplies have a capacitor input type rectification circuit. When the power is turned on, a surge current is generated, causing fatigue of the switch contacts, causing problems such as increased contact resistance and adsorption. In theory, it is believed that the number of on and off of the switch is about 10,000 times during the expected life of the power supply.

What are the factors that affect the life of a plant light source? In general, the life of a plant light power supply depends mainly on the above factors, but there are some minor factors besides these. For example, the voltage input of an unstable power grid will impact the components of the plant light power supply. Affect the life of the power supply.
