The led fiber optic illuminators systems

The led fiber optic illuminators
the led fiber optic illuminators systems used light source loaded to housing with fiber optic lighting The device call light-emitting device.The outer cover made of sheet metal or aluminum alloy. We sometimes call the light emitting device for projector. The light emitting device can be filtering a majority of infrared (Link the ir led strips produce IR) and Ultraviolet (UV) energy with the filter head. Therefore, fiber optic lighting system for indicating textiles, painting an food, cultural relic is ideal.Because the light is transmitted from the lamp to the end of the fiber Light emitting device can also be equipped with eight color glass fiber disc to achieve continuous or fixed color changes. In addition, the campaign color palette of available computer processing to provide special effects. For example: light timing changes or as the moment the light strobe. Finally, in order to increase the power for complex lighting device.Can also be several sets of front and rear vertical connection or the light emitting device connected in series? The light emitting device includes a light source, a reflector,ultraviolet (UV) and infrared (IR) filter and rotary glass color wheel(optional). According to the interior of the light source is different,, generally divide into tungsten halogen lamp series and metal halide lamp two series. The power of the light source is a halogen tungsten lamp as 50W or 75W 100W the input voltage of AC 12V(device with power transformer).Applicable to a museum or exhibition hall on the temperature , Humidity and ultraviolet, infrared control requirements have special places, metal halide lamp light source power is generally 150W or 25W, the input voltage of AC110V, suitable for the outline of a building façade lighting and so on brightness demand higher place, often used in making fiber chandelier.According to the different level of protection, in generally light emitting device is divide into indoor an outdoor two types rotary glass color plate can be equipped with up to eight colors automatically transform.The device can be controlled by the computer according to the change require. But also by the sound system output audio signal synchronization control。Apply it’s  own power supply AC plug 110V,50HZ.By light size and required luminance of single piece fiber generally depends on the power and bype of led resource. The optical fiber lamp is ideal that has a very small area of light and  Luminous flux output high lamp light source reflector mirror rear and lens front helps to effectively put the light transmission input fiber.The commonly used lamp comprises a 50 to 100W low power MR 16 70W to 250W and metal Halide(M-H) lamps there are 3W, 5W, 8W, 16W, 27W, 45W,75W of LED optical fiber light source color plate supply the meteor. Synchronization, wireless remote control, doubles models.

Two different methods with ir emit light. Which one should you use?

There are have usual infrared ray emit of ir led strips: ir light  940nm&850nm respectively.
Due to the ir led of 940nm infrared photosensitive ability is limited, 940nm at night and 850nm imaging distance there is a gap,so the application is not widespread. At present, the main application of 940nm series infrared light led strips in special field. The advantage is quite obvious.
First,Concealment stronger. Infrared 940nm infrared light strips to work at night, issued by the infrared spectrumare totally beyond human recognition, human eye is not visible directly. The camera using the lamp panel is widely used in the Concealment place, especially suitable for monitoring high confidentiality requirements, is not easy to be noticed.

Second, visual disturbance. Ordinary 850nm infrared light ir led strip at work will be issued more obvious infrared light, to people’s normal work and study there are some visual disturbance, easy to make people tired. Especially in the hospital and other places, too strong infrared light will affect the patient’s rest, causing unnecessary trouble. I f the camera is for internal use infrared light 940nm, that no problem? also need to confirm that the CCD machine inside the machine can sense infrared 940nm.

Why use wavelength of 850nm an infrared led in infrared cameras

Why use wavelength of 850nm an infrared led in infrared cameras

There are many different wavelengths of infrared transmitting tubes in led mark, withwavelength of 850nm ir led strip or 940nm ir led strips is main force. So why use 850nm wavelength infrared in  infrared cameras ?

First of all, we come to knowledge about infrared cameras. In simple word, infrared camera is used to sense infrared and Image forming, it can be divided into 2 types: one is the passive infrared cameras, mainly for the military; another is active, mainly civilian. Any objects in absolute zero(-273 ℃) above will emit infrared light, but the infrared intensity, so in here we can only use passive infrared camera to capture images. But passive infrared camera, the price is very expensive, so not suitable for civilian & household use. The active infrared camera is the use of infrared emission emitted infrared, infrared is adopting the infrared principle to capture images, so the price is cheaper. Active infrared camera can receive infrared distribution center wavelength as 830 – 950nm. Within this range, Thus The 850nm or 940nm wavelengths of infrared transmitting led are suitable for, can make an infrared camera with a red explosion and none red explosion. Therefore, Infrared cameras are therefore not only 850nm IR led can be used, and not with the others. The reason to use 850nm infrared led is 850nm wavelength sensitivity thanin the 940nm wavelength sensitivity to 10 times better. as well as transmit power range, distance farther, by contrast, 850nm this slightly red bursts of infrared tube more suitable for application on the infrared camera, , and thus become the mainstream.

Two major advantages of ir led strips

Two major advantages of ir led strips
First,  low heat. All along, the biggest problem of infrared light board is board hot, if you solve the heating, the service life of infrared light board can be extended exponentially. LED infrared strip light is composed of a plurality of beads, is an independent luminous body of each led strip lamp, there have some space between the heat lamp and lamp, they are at work, less heat, heat is easy dissipated. Array infrared light board, it is a single high-power LED chips, in the power of work, not just the make a lot of heat, and the heat is difficult dissipated.

Second, long service life. Ir led strips has been used for 10 years in the security industry, and the array infrared light is only five or six years, I remember array of infrared light board just come out, people say the array light is good, but use after a period of time, get result that the array of Infrared more easily broken.This is true, usually the life of the LED infrared light board than the array of infrared light board much longer, the main reason lies in the array light board short life did not solve the problem of heat dissipation, heat is too large and can not be dispersed, and finally to the wick premature aging, shorten the service life.

The ir technical

With the development of economy, people in meet the basic needs of clothing, food, shelter , after the trip, People use these ir led and ir led strips to connect with Their lives, Especially  personal and asset security needs naturally elevated to a new height. Video monitoring because of its intuitive and continuity to become preferred way of security technology . Infrared night vision camera in meet the night environment hidden and shoot clear picture is widely used in video surveillance.

The technical principle

Infrared night vision camera is mainly used in visible strong light or dark light environment, using infrared transmitter device active infrared light is projected onto the object, after the infrared light reflected from an object, and enters the lens final the picture are emerging. At this time we are seeing is the reflection of infrared light into the screen, rather than visible light reflection into the picture, then it can be taken to the dark environment, invisible to the naked eye images Light is an electromagnetic wave, the wavelength range from several nanometers (1nm=10-9m) to 1 mm (mm). Visible to the human eye is only part what is called visible light and visible light in the wavelength range of 380nm~780nm and visible light wavelength from long to short is divided into red, orange, yellow, green, cyan, blue, purple, violet wavelength than known as the short ultraviolet wavelengths than red long known as the red outside light. Often people will be divided into the near infrared and far infrared, in the three part. Near infrared wave length of 0.75 ~ 3 micron to; infrared refers to the wavelength of 3 ~ 20 micron; far infrared refers to a wavelength of 20 to 1000 microns. Because the infrared light to visible light, the naked eye can not see it in the space of existence, and therefore an LED that emits infrared light emitting diode infrared light active form of infrared light is widely used in night vision surveillance require covert, in place Traditional low lights hidden night vision surveillance .Infrared light have different power and wavelength of 715 850nm, two kind wavelength determines the different infrared distance and effect

Infrared interface

Infrared communication is a kind of cheap, close, no wiring, low power consumption and strong secrecy communication program. in PC machine is mainly used in wireless data transmission but has gradually begun widely used in wireless network access and near distance remote control for home appliances. In view of the many advantages of infrared communication, and now almost all motherboards offer that an infrared interface for users easy to use it for communication with the device(infrared interface), such as notebook computers, printers, Modem, handheld computers, mobile phones and so on. But the computer motherboard only provides the infrared transmitting and receiving device interface, does not provide a complete, so users still need to purchase the infra-red connector when user want to use infrared communication.

The component selection

Select and test primarily components— receive launch tube and tubes.

1 test the infrared emission tube: infrared emission tube is actually special diodes(or is IR led strips), with a resistance profile measurement of millimeter , the launch tube reverse resistance is infinite, the forward resistance is generally about 500K. If you have a laptop, you can Take an infrared interface to PC and GND leads IRTX two lines, IRTX connect the positive launch tube, GND connected to the negative of the launch tube, the alignment of the launch tube infrared emission windows laptop, the infrared monitoring device of notebook computer “will find your PC”.
2 test the infrared receiving tube, infrared receiving tube is a diode, the forward resistance more than 500K, and is not affected by illumination, reverse resistance in the absence of direct light, generally more than 300K, the glare should be less than 10 ohm, sometimes is negative, because the PN junction diode will get electricity when the light energy into strong light,and formation of the 0.7V. node voltage .because in the light irradiation the PN junction diode, light will be converted into electrical energy, the formation of the node voltage 0.7V.

Infrared technology

Infrared technology
When an object’ temperature is higher than above absolute zero, able to produce infrared radiation as ir led strips. The wavelength of the radiation is widely used,  but we are committed to the use of such radiant energy, in fact cannot heating on an object to be heated direct. Infrared ray is a kind of electromagnetic radiation,
visible light wavelength is long, generally in accordance with the peak energy or peak emission wavelength is divided into the following three:

LW: ceramic infrared radiation heater

ceramic infrared
ceramic infrared equip

MW: quartz plate infrared radiation heater

Sw: quartz halogen infrared radiation heater

quartz plate infrared radiation
quartz plate infrared
