Infrared light is a relatively special way of lighting, it is the use of the human eye does not feel the near-infrared wavelength spectrum to provide lighting, so it has a good concealment, IR Illuminator high luminous efficiency advantages.
Ordinary CCD black and white camera can not only feel the visible light, and can feel the infrared light. This is the use of ordinary CCD black and white camera, IR Illuminator with infrared light can be more economical to achieve the basic principles of night vision.
The spectral characteristics of ordinary color cameras can not feel the infrared light, it can not be used for infrared night vision. The infrared radiation power is proportional to the forward operating current, IR Illuminator but when the maximum rating of the forward current is approaching, IR Illuminator the temperature of the device rises due to the heat dissipation of the current, causing the light emission power to decrease.
Infrared light for nighttime concealment or no disturbing monitoring, IR Illuminator to do auxiliary lighting to use, and the human eye is not sensitive. Get a black and white image.
Single-chip LED production process is simple, easy to protect the quality, IR Illuminator low heat, light optical system is reasonable, is to do infrared light infrared camera ideal device, in fact, the application life of up to 100,000 hours or more. So naturally in the technical bias on a single chip. But the single-chip infrared light still has a lot of constraints, for example, some LED chip level is very low, IR Illuminator impurity exceeded; some production process, but off, there are leakage scenarios; some super power applications, rated 20mA, but the application of more than 50mA; Some do not maintain the circuit, or circuit design is unreasonable, IR Illuminator which will lead to single-chip LED infrared light quickly broken.
To protect the life of infrared light, first of all to use high-grade LED chip. High-grade chip power, good consistency, high luminous efficiency, heat is very small, IR Illuminator a high-grade LED than the quality of ordinary LED 10 times, of course, the price is higher. Second, the optical system design should be reasonable, light to be uniform, the utilization rate should be high, heat faster. Third, to strictly control the working voltage. LED is very sensitive to voltage, the voltage is slightly higher LED die will burn; IR Illuminator and the voltage is slightly low will be greatly reduced the amount of light. IR Illuminator It is best to match the high-quality switching power supply, the AC input voltage from 170 volts to 270 volts best can be better regulator to fit the unsuccessful power supply environment. Fourth, the input power cord is best to use anti-high / low temperature, ultra-soft anti-tortuous. IR Illuminator There is a manufacturer of the infrared light, the input power cord can be in the low temperature of minus 60 degrees, high temperature on the 250 degrees normal application, IR Illuminator minus four or fifty degrees cable is still soft as silk, this product was trustworthy.
