 Life and the distance of the infrared light source related to the camera in my rough talk about how it works. In general, the infrared light radiated power is proportional to the forward operating current, but close to the maximum rating of forward current, the temperature of the device due to the heat consumption of the current rise, the light emission power down. Infrared diode current is too small, will affect the radiation power play, but the operating current is too general impact of its life, and even infrared diode burned. Current begins to flow when the voltage across the positive threshold voltage (about 0.8V), and a very steep curve, indicating that the current requirements are very sensitive. Therefore, the requirements of current and accurate, stable, and otherwise affect the radiation power of the play and its reliability. Radiated power with increasing ambient temperature (including its own heat generated by the environmental temperature) so that the radiated power decline.
