Working conditions of Infrared led
Infrared light radiated power is proportional to the forward current, but close to the maximum forward current,temperature of the device current consumption due to the heat rises,cause light emission power decreased. Ir led strip’ current too small, will affect the radiation power play, other conclusions will affect its life when Ir led strip’ current too big, cause severe damage to led strip.When the voltage across the threshold of positive voltage  current begins to flow and That’s an very steep curve，show that the working current is very sensitive. Therefore, the operating current is required to be accurate and stable, otherwise it will affect the radiation power and its reliability. With the increase of the temperature in radiation power’ changes(including its own heat generated by the ambient temperature),so that radiation power will decrease. The Infrared led especially long-range’ Infrared led,   should pay attention to the design and selection that lpd6803 led strip of problem. Therefore, the use of IR infrared lamp must have constant current power supply, good heat dissipation and good design.
