What are Illuminators?

Illuminators

Illuminators are basically lights and any device that provides illumination or provides to a certain area. There are two types of illuminators. The first type of illuminator can be seen by humans and humans will notice that the area is being illuminated. The other type of illuminator is able to illuminate an area without humans noticing that the area has been illuminated.


One example of the first type of illuminator is the fibre optic illuminator. Fibre optic illuminators are responsible for providing a light source for fibre optic cables. The light that travels through the fibre optic cables can be used for many applications such as a fibre scope which is used to view tight areas or internal organs. There are different types of illuminators that vary according to the amount of light they produce. This will determine if the illuminators usability in different settings. Fibre optic illuminators are also able to light up a small room when combined with a glow cable.


A fibre optic illuminator consists of a lamp connector that is connected to the current that powers it. Then there is the lamp which provides the light source; some illuminators have cooling fans to cool the illuminator and color wheels to change the color of the light. There is also a port so that the fibre optic cables can be connected. The light bulbs and lamps of the fibre optic illuminator usually have some sort of reflector so that the light is directed towards the port and into the fibre optic cables. The lamps are usually made out of metal halide as it provides the brightest source of light. However, the lamps can also be made out of quartz halogen if the desired brightness is lower.


These illuminators have an on and off switch that have to be manually operated although there are some systems that have remote controls. For example, if these fibre optic illuminators were to be used with digital multiplexing systems either a remote control can be used or the system can be used to create special lighting and color effects. The fibre optic illuminators may also be used in laboratory settings to provide a source of sensitive lighting when working on a specimen or subject. Many exhibits and showcases also use fibre optic illuminators to focus its attention on the exhibit. Fibre optic illuminators are also commonly used in architectural settings to give off different moods and designs.


The next type of illuminators is used to light up an area without humans noticing. These types of illuminators are known as infrared illuminators. These types of illuminators are usually used for security purposes such as lighting up an area so that a security camera is able to capture the image. This is because the technology that security cameras use is very sensitive to infrared lighting. Infrared illuminators allow security cameras to capture clear video footage even if the area lacks normal lighting. Since infrared illuminators use light emitting diodes, they are also very efficient as very little energy is required for the illuminators to run and they can run for 100,000 hours.


Security cameras are often used to protect buildings, streets and stores from vandalism or theft. In the day time, the chances are minimized as most likely there are people around. It is usually during the night time when these crimes happen. Most of the times, store and building owners turn on normal ambient lights to illuminate the area so that the cameras are able to capture any suspicious footage. However, this means that the criminal is able to see the security camera as well and most likely avoid it. For this reason, infrared illuminators are used to provide good lighting for the security camera without being detected by the criminals.


Thus, illuminators have plenty of uses and there are many more types of illuminators that can be used depending on the purpose. They have evolved from simple light bulbs to advanced technology that uses fibre optic cables and infrared LEDs.
