Infrared light features of a new generation infrared camera
April 28, 2024
(1) The infrared laser beam irradiation distance of the infrared camera is independent of the number of wafers.
Infrared camera spot array infrared lamps use a special "wafer structure", "crystal growth process", "encapsulation technology", and the infrared camera's infrared lamp brightness standard is completely different. When the infrared camera was just born, in order to identify and monitor the distance 50 meters away, it would take 60 24-mil infrared lamps to achieve this. Due to the large size, high power consumption, and low heat dissipation, the lamp has a lifetime of less than one year. After the infrared camera adopts the second generation array infrared lamp, it is still 60 pieces of 24 MIL, the volume is reduced several times, the heat-dissipating ability is improved effectively, and the life span is extended by 5 to 10 times. Now infrared cameras use the third generation of dot-matrix infrared lamps, you only need a 42mil to get it, smaller size, longer life, and extend the recognition distance to 80 meters. The reason that a spot-array infrared lamp can illuminate such a long distance just because of an infrared lamp is mainly because of its extremely high photoelectric conversion efficiency. Because of this, the products assembled using this chip have extremely low heat and long life.
(2) The intensity of the infrared infrared light beam of the infrared camera is no longer based on power.
Infrared camera generation of LED infrared light, second-generation array of infrared light, people often use infrared chip points to distinguish between the strength of the infrared light, brightness and darkness. Since the conventional light-emitting chips have different sizes and powers, infrared lamps with large natural power have high brightness and a long irradiation distance. In addition, if you use this method to distinguish the infrared camera's infrared lamp is good or bad, you need the photoelectric conversion efficiency of the infrared lamp. The photoelectric conversion efficiency is different. It is difficult to assess the quality of the infrared lamp simply based on the infrared lamp power parameters of the infrared camera. After the introduction of the dot-matrix infrared lamp, this situation has been completely changed. People can completely disassociate themselves from the infrared lamp power evaluation method and distinguish the intensity, brightness and darkness of the infrared lamp through the optical output (mW).
People use the infrared camera infrared chip points to distinguish the intensity of the infrared light, light and dark. After that, due to the different sizes of the chips and the power is different, the input power is used to distinguish between the strength and the intensity of the infrared lamp. However, the input power to distinguish between bright and dark, the chip's "equivalent luminous efficiency is the premise. In the past, it is true that the luminous efficiency of each brand of chips is slightly the same, so that the comparison of light and dark methods is not controversial, but After the introduction of the company's newly introduced high-efficiency infrared chip, people will only be able to distinguish the intensity of the infrared lamp by its optical output (mW), and the brightness of the infrared lamp will be different from that of the infrared lamp. After the crystal method to the thermoelectric separation packaging technology, our light-emitting components are greatly superior to the traditional infrared light-emitting LED, and also break through the "light-emitting efficiency" that we have identified for a long time, thereby reducing heat generation. In this way, under the same brightness, In addition to low power consumption, the heat sink required for less heat is smaller, and the overall product volume can be made smaller. More importantly, because the temperature is not high, it is also harmful to other electronic components around it. This is not one of the advantages of the dot matrix infrared camera.
