What are the different types of IR lighting?

Infrared (IR) lighting is used in situations where it is necessary to see in low or black situations. Otherwise, without any form of IR lighting, the camera could not create a recognizable image under poor lighting conditions. The main types of unnatural IR lighting are filtered bulbs or tungsten lamps and high -performance lighting diodes (LED) illuminators. Laser diodes are the most effective type of infrared illuminators, but are least predominant. Nature also provides its own form of lighting over the moon and the sun, to some extent. They are marked as 0.7 micrometers or more and are further divided into regions. The scope and specific designation of these regions differ, but normally decompose into almost infrared (NIR), medium infrared (MIR) and Far infrared (FIR). IR lighting comes into play at the NIR level, from 0,7-3.0 micrometers. This technology increases the ability of infrared devices to see into the invisible part of the spectrum and capture images with a clearly identifiable detail. The application tends to determine the IR lighting type according to the required distance, spectrum and life.

Closed circuit safety systems (CCTV) often use tungsten lamps because they are the lowest alternative for long range solving. This type of lighting consists of a lamp combined with an IR filter that works to remove visible light. Filtered bulbs and tungsten lamps use more electricity than other options and usually need to be set to carry out excess heat delayed by lamps.

The

LED with high performance provides a performance that is comparable to lamp performance, but with a much longer life. This causes low operating costs, but poor monitoring of a wide angle and the effect of a "hot spot" where the center of the image is too illuminated and indistinguishable against low costs. LED Illuminators have several attributes that make them attractive for many APsLiccation for night vision. They can see in weather conditions such as fog and snow, are able to capture video at high speeds and can reduce or eliminate shadows.

IR IR based on laser diodes are the most effective and expensive. Improve the efficiency of the LED type without sacrificing distance. For this reason, the IR lighting laser diode type is used in higher night resistance, glasses and other similar aids. As the costs fall and replaced by older systems, CCTV security systems are likely to expand their use of diode IR lighting.
