What Is an Infrared LED?

Infrared light emitting diode (LED) is a near-infrared light emitting device that converts electrical energy into light energy. It has a series of advantages such as small size, low power consumption, and good directivity. It is widely used in remote control, telemetry, optical isolation, and optical switching. , Photoelectric control, target tracking and other systems.

Due to the infrared light emitting diode, it emits 1 ~ 3m

1. The wavelength of light is smaller than this number, which is visible light. We can still see the red dot at 850 nanometers. If it is more than 900 nanometers, we will not see it.
2.After 8000 hours, its intensity decayed to 85%
3. This is an automatic color-to-black-and-white camera. When the light is too dark, the camera's illuminance is insufficient. You need to fill the light. You are using infrared light-emitting diodes (LEDs) for lighting. Because the infrared light cannot reflect the color, the camera is no longer Color coding only outputs black and white signals (brightness signals). This benefit is to reduce the color noise caused by color coding. Although it is further possible that your camera has the effect of dual filter conversion, it is already a black and white signal, so the filter used for color correction is also cut off to facilitate the passage of infrared rays. In this way, when the system feels The time until the illuminance is not enough to turn on the led and cut off the filter to terminate the color coding is within 0.5-2 seconds. (It may not have dual filter switching effect, and the information you provided does not include sufficient conditions for dual filters.)
Conversely, black and white to color is the reverse flow of this.
