Array camera - principle explanation
Array camera - principle explanation
Array camera - principle explanation
Look from exterior array infrared camera is different from traditional ordinary camera is the only one lamp, and ordinary infrared cameras are dozens of small infrared lamp aggregation around the lens, this is the different appearance, followed by the array type camera do not emit bright red light in the darkness.
The mainstream, the defects of infrared camera
The mainstream of the infrared camera by putting a single infrared LED encapsulation combinations, fixed in the camera around, like fill light initiative to provide for the cameras. As we know, a single LED infrared diode effective efficiency is about 20%, at the same time there is an obvious flaw, that is limited by heat treatment and luminous power greatly decreases, and that lighting distance reduced, often can not meet the nominal irradiation distance. Another is the volume of a product, in limited space, in order to meet the lighting needs and effective distance, have multiple LED tube assembly, due to increased volume, temperature also increases at the same time, not easy to heat dissipation and application. LED heat can't effective thermal conductivity, which leads to the machine temperature increase, the serious influence the performance of the CCD camera, a long time, it is easy to burn out the CCD and circuit board, which is why the mainstream infrared cameras on the market life is short, use after a period of time, obvious effects of the main causes of variation.
Second, array camera will solve this problem
First of all, based on the problems existing in the market and the urgent demand, infrared lamp Array on the basis of the original LED lamp, is improved, the Array infrared camera refers to the kernel for the cameras on the infrared lamp Array LED IR. LED Array (light emitting diode Array) is to integrate the luminescence unit height, but under the same brightness index than ordinary LED lamp products is small in size, quality and effectiveness of the far infrared lamp, traditional Array infrared night vision technology, the essence is the manner in which the transmission infrared light waves by the camera active night vision effect, but has adopted the advanced packaging technology, will be dozens of high power, high efficiency infrared wafer encapsulation in a plane. Infrared lamp array type of thoroughly solved the problems of ordinary lamp, greatly enhance the charm of the infrared camera.
Secondly, the array infrared camera biggest advantage is to solve the problem of the LED light source heat dissipation, high luminous intensity and luminous efficiency, the photoelectric conversion efficiency about 25% higher than that of ordinary infrared LED camera, efficiency can reach 45%, greatly reduce the energy consumption and at the same time increase the lighting distance, also prolong the service life of the camera, array infrared night vision camera, the biggest advantage is that its service life is commonly nine times the service life of the ordinary infrared camera.
The main advantage of the three, the array camera
Light even. As we know, in front of ordinary infrared leds are a small sphere. When combining multiple infrared leds around the camera lens, the light emitted is multiple spot of overlapping, overlap will be particularly high brightness, can produce what we call "flashlight effect", because the uneven illumination, so of course the night vision effect is uneven. The array infrared camera was quite a big point light source, through the special optical design, make the light even light monitored objects, makes monitoring in the middle of the picture and in the surrounding brightness is consistent.
Life is long. Ordinary LED effective life of 1200 hours, and the effective life of the LED Array is 10000 hours, if in terms of seven to eight hours a day using infrared lamp, LED can effectively use about half a year and LED Array can effectively use about four to five years. In life for ordinary lamp are seem to be very cost-effective.
Infrared distance. The higher brightness, the light irradiation distance is more far, although individual leds can increase the current to increase the brightness, but the material limitations, infrared photoelectric conversion efficiency is not high, only 20% of the light, the rest is heat. With improving the brightness, can produce a lot of heat energy, while a high working temperature of the CCD camera, is no good. And array infrared camera light source, with dozens of high efficiency and high power by encapsulation wafer by using technology in one plane, good heat conduction device. At the same time increase the photoelectric conversion efficiency, brightness is about 100 times that of the individual leds, and irradiation distance is farther.
