(1), at night when the infrared light is only two bright, IR Illuminator indicating that the current ball machine magnification magnification is a small magnification (if the magnification in the case of small magnification is also bright light, then prone to fill light surplus lead to The phenomenon of violence);
(2), at night when the ball machine has two infrared light does not shine, the other infrared light is bright, indicating that the current ball machine magnification is a large magnification (if the magnification factor in the case of large magnification to see The object is relatively far away, the opening of the low beam for the ball machine to illuminate the object does not make any fill the role of light so it is closed);
Multi-chip LED also has two kinds of situation, one is contains 4 to 8 chips; the other is an array of light-emitting films, containing 10 to 30 chips. Why do the chip? The potential reality is: infrared light irradiation interval is not enough because the energy is not enough, IR Illuminator more chips together, of course, the energy is large, so the usual interval is more distant. If this can guarantee the infrared light of the light reception rate is right, but the receiver can not guarantee the premise, no more than the infrared light chip will only run the temperature is too high and affect the life expectancy, and can not really improve the infrared light The interval of exposure.
In general, multi-chip infrared camera in terms of performance or because of ordinary halogen lamps, but multi-chip LED due to its inherent defects in the structure is not the focus of light, light optical system is unreasonable, useful light efficiency is also low. For example, IR Illuminator array LED, the current up to 1000mA or more, the foundation is just a penny coin size, heat has become a problem. And we do know all the technology, LED is most afraid of the high fever, ah, heat is not bad is not bad ah At the same time, multi-chip LED production requirements are very strict, each chip can not have a little difference in performance, or a chip is broken, then the overall chip is the overall LED. In general, applied to the explosion-proof infrared camera above, IR Illuminator the existing multi-chip technology LED life is far from enough
Single-chip LED production process is simple, easy to protect the quality, 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, impurity exceeded; IR Illuminator 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, 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; and the voltage is slightly low will be greatly reduced the amount of light. 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, minus four or fifty degrees cable is still soft as silk, this product was trustworthy.
