Mini IR Illuminator One is 4 to 8 chips, and the other is the array of light-emitting tablets, containing 10 to 30 chips. Why do long chips? The potential reality is: the infrared light irradiation interval is not enough because the energy is not enough, more chips together, of course, the energy is large, Mini IR Illuminator so usually the irradiation interval farther. If this can protect the infrared light of the reception rate, is right, but the reception rate can not be guaranteed under the premise that a lot of infrared light chip will only cause the operation of the high temperature through the impact of life, and can not really improve the infrared light irradiation interval.
Overall, the multi-chip IR camera in the performance or because of the common halogen lamp, but the multiple-chip led because of its inherent defects in the structure does not have a luminous focus, the light-emitting optical system is unreasonable, the light efficiency is also low. For example, Mini IR Illuminator array-type LED, current up to 1000mA above, the basis is only a penny coin size, heat dissipation becomes a problem. And we do know the technology, LED is the most afraid of high fever ah, the heat is not bad is not good. At the same time, multi-chip led production requirements are very stringent, each chip can not have a little difference in performance, or a chip broken words hurt is the overall chip led. Overall, the application of the explosion-proof infrared camera, Mini 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 calorific value, luminous optical system is reasonable, is to do an explosion-proof infrared camera infrared lamp ideal device, in fact, the application life of up to 100,000 hours. So naturally it is technically biased towards a single chip. But the single chip infrared lamp still has many restricting factors, for example, some LED chip level is very low, impurities exceeded, some production technology is not clearance, there is a leakage of the scene, some super power applications, rated 20mA, but the application of more than 50mA; some do not maintain the circuit, or circuit design unreasonable, Mini IR Illuminator these will incur a single chip LED infrared light quickly broken.
To protect the life of the infrared lamp, we must first choose the high grade LED chip. High-grade chip power, consistency, high luminous efficiency, heat is very small, a high grade led than the quality of ordinary led 10 times times better, of course, the price is also higher. Secondly, Mini IR Illuminator the optical system design should be reasonable, luminous to be uniform, high utilization rate, heat dissipation. Third, to strictly control the operating voltage. Led to the voltage is very sensitive, the voltage slightly higher led tube core will burn off, and the voltage slightly lower the luminous quantity will be greatly reduced. Best match the high quality switching power supply, AC input voltage from 170 volts to 270 volts can do a better voltage regulator, in order to fit the unruly power supply environment. Mini IR Illuminator Four, the input power cord is best to choose against high/low temperature, super soft resistance twists and turns. There is a manufacturer of infrared lights, input power cord can be used in Low-temperature $number, high-temperature 250d Normal application, minus 40 or 50 degrees of cable still like silk is generally soft, such products are trustworthy.
Therefore in the explosion-proof camera infrared lamp selection also has the skill, understands this knowledge, believed in the later explosion-proof camera's choice, will have the help to you.
