(1) High brightness: Obviously, the higher the brightness, the farther the light shines. The output light power of a single LED is generally 5~ 15mW. Although the brightness can be improved by increasing the current, the limitation of the material itself is that the photoelectric conversion efficiency of infrared light is not high, and only 20% of the light is thermal energy.
(2) Small size: each LED array can integrate up to 60 LED luminescent crystals, and the integrated volume is only the size of a fingernail, so the volume of the finished product will not be too large. Because LED-Array is a highly integrated LED, its volume is much smaller than other products. As mentioned above, array infrared adopts highly integrated advanced packaging technology, and an array infrared chip packages dozens of chips. Imagine the volume of dozens of individual LEDs combined together. Small size is mainly convenient for application. If dozens of infrared light sources combined with single led are installed on the high-speed ball machine, the effect can be imagined. The light-emitting angle of ordinary products is generally 7- 10, so a flashlight-like beam is formed, and the angle of our luminous body can reach 180. The whole space can be evenly illuminated indoors. The light output of a single LED is 5mw- 15mw, while the light output of an LED array reaches 800mw- 1000mw, which is only the size of a coin. This shows that the LED array has a clearer, brighter and longer monitoring picture than similar products on the market.
3. Long service life: The service life of ordinary LED products is generally 6000 hours, and the service life of LED array is 50000 hours. Generally, the damage of LED lamps is not covered by the product warranty, while LED-Array can provide a two-and-a-half-year warranty period, and its service life is nine times that of ordinary LED infrared cameras. The common LED infrared camera puts the LED light-emitting tube and the camera in a cavity, and the heat of the LED light-emitting tube cannot be effectively dissipated through the PCB board, so the temperature problem seriously restricts the service life of the CCD. After three months of use, the ordinary LED infrared camera began to show signs of aging, such as blurring, whitening and insufficient contrast, which directly affected the use effect of the product and even scrapped the whole camera.
efficiency
4. High efficiency: determined by the characteristics of the semiconductor itself, its luminous efficiency and heat dissipation performance are a virtuous circle. The photoelectric conversion efficiency is improved by 30%, and the power consumption is reduced at the same lumen 1/3. The lower the heat, the better the heat dissipation performance, and the lower the working temperature, the lower the working temperature can better ensure its luminous efficiency. Instead, it falls into a vicious circle of declining efficiency. In addition, our power supply system adopts self-patented high-frequency sharp pulse power supply to ensure higher efficiency. No attenuation, special packaging technology can effectively solve the heat dissipation problem. High-performance light-emitting crystal array arrangement effectively solves the heat dissipation problem through special packaging, so that the luminous body is always at normal working temperature and obtains stable power output for a long time.
light
5. Uniform light: As we all know, there is a spherical surface in front of every ordinary infrared LED, which is an independent optical design to change the spot size. When a plurality of infrared light-emitting diodes are combined around the camera lens, the light emitted is composed of a plurality of overlapping light spots, and the overlapping parts will have extremely high brightness, and at the same time, a circle will be formed, that is, the "flashlight effect", and the night vision picture effect is of course uneven. Array infrared camera is equivalent to a large point light source. Through special optical design, the light shines evenly on the monitored object, and the brightness in the middle and around the monitoring picture is consistent. In addition, our array infrared camera has been further improved according to the different refractive indexes of infrared light and visible light passing through the lens and the photosensitive characteristics of CCD. Ensure that real colors and accurate and clear picture effects can be obtained day and night.
