Array-type infrared camera refers to the core of the infrared lamp is LEDIRArrayLEDArray refers to the light-emitting diode array, which is an efficient and long-lived infrared night vision equipment. Different from the traditional LED infrared lamp, the outstanding feature of the array infrared lamp is long service life, no significant attenuation of light within 2 to 3 years, uniform light, fine detail, and high resolution. The night vision image of the array camera is brighter than the infrared light. Little, no vignetting, no even dark corners of the image, largely solves the flashlight effect of the picture, can significantly improve the night vision effect of the camera, and at the same time greatly reduce the volume of the digital video file, saving the hard disk recorder space.
The main advantage of surveillance cameras array <br> <br> high brightness. Obviously, the higher the brightness is, the farther the light is irradiated. The output power of a single LED is generally 5~15mW. Although the brightness can be increased by increasing the current, the limitation of the material itself is the photoelectric conversion efficiency of infrared light. Not high, only 20% of light, the remaining 80% is thermal energy. Therefore, while increasing the brightness, more heat energy is generated, and it is obviously not feasible for the key device CCD of the camera, which requires strict working temperature. In addition, multiple LED multiple combinations use the PCB board as a carrier, and the heat dissipation performance is not good. The array of infrared camera light source, through the dozens of high-efficiency and high-power wafer by high-tech package on a flat surface, a good configuration of the heat conduction device. At the same time increase its photoelectric conversion efficiency, brightness is about 100 times that of a single LED.
Small size . Each LEDArray integrates up to 60 LED light crystals. The integrated volume is only the size of the fingernail cover, and the finished product volume will not be too large. Because LED-Arrays are highly integrated LEDs, they are much smaller than other products. As mentioned earlier, the array infrared uses a highly integrated advanced packaging technology, an array of infrared chips encapsulating dozens of wafers. Imagine the volume of a dozen individual LEDs combined together. The main advantage of the small size is that it is easy to use. If an infrared light source with a combination of dozens of individual LEDs is to be installed on a high-speed dome camera, the effect is conceivable. The light angle of ordinary products is generally 7°-10°, so a beam of light like a flashlight is formed. The angle of our luminous body can reach 180°. The entire space can be evenly illuminated indoors. The single LED's optical output is 5mw-15mw, while an LED-Array's optical output reaches 800mw-1000mw, and the volume is only a penny coin size. This shows that the LED-Array is clearer, brighter and more distant than the similar products on the market.
Long life . The life of common LED products is generally 6000 hours, and the lifetime of LED-Arrays is 50,000 hours. If the LED lamps are damaged, they are not covered by the warranty of the products, while LED-Array can provide two and a half years of warranty. The deadline is 9 times that of ordinary LED infrared cameras. The ordinary LED infrared camera places the LED light emitting tube and the camera in a cavity, and the heat of the LED tube cannot be effectively dissipated through the PCB board. The temperature problem seriously restricts the service life of the CCD. After 3 months of using ordinary LED infrared cameras, they begin to show signs of aging. The problems such as blurred pictures, whitening, lack of contrast, etc., have a direct impact on product use results, and even the entire camera is scrapped.
High efficiency . Determined by the characteristics of the semiconductor itself, its luminous efficiency and heat dissipation performance is a virtuous circle. The photoelectric conversion efficiency is increased by 30%, the consumption power of the same lumen is reduced by 1/3 of the heat, the better the heat dissipation performance, the lower the operating temperature, and the lower the operating temperature, the better the luminous efficiency. On the contrary, it is a vicious cycle of falling into efficiency. In addition, our power supply system uses its own patented high-frequency spike power supply to ensure greater efficiency. No attenuation, special packaging technology effectively solve the problem of heat dissipation High-performance array of light-emitting crystal array, after a special package, effectively solve the heat problem, is the light body at normal operating temperature, in a long time to get a stable power output.
Light evenly. As we all know, each ordinary infrared LED has a sphere in front of it, which is a separate optical design to change the size of the spot. When multiple infrared LEDs are combined around the camera lens, the emitted light is composed of multiple light spots overlapping. The overlapping part will have particularly high brightness, and at the same time form a circle, that is, "flashlight effect", and the night vision screen effect is of course It is uneven. The array infrared camera is equivalent to a large point light source. Through special optical design, the light is evenly irradiated to the monitored object, and the brightness of the middle and the surrounding of the obtained monitoring picture is the same. In addition, our array infrared cameras are further improved and improved based on the difference in the refractive index of infrared light and visible light passing through the lens, and the CCD's light-sensing characteristics. To ensure that the colors are true during the day and night and the focus is accurate and clear.
