Monitor the Application of Ledled Lamp Beads in the Middle of the Infrared Lamp Beads

As the demand for night vision monitoring in the security video surveillance system is getting wider and wider, the sales of infrared monitoring are increasing day by day. In order to get good night monitoring quality, we can choose the following points when choosing infrared devices: 1. Infrared The choice of light source infrared is an unpredictable light of 780nm. 1. Plugs in the infrared light emitted by incandescent lamps or lamps. That is, the visible light filter is installed on these two types of lights, filtering the visible light, and only the invisible infrared rays are shot; 2. Use infrared light diode LED or LED array to produce infrared light. This device is infrared to produce infrared light through the composite acupoint of electrons and empty LED lamp beads in gallium arsenidized semiconductors;. However, it must put the electronic inspiration or pump to a higher energy state, and reverse through a small particle distribution to maintain the sharp radiation infrared light. The first light source is a hot infrared light source. The most advantage of its year is that it can be made into a relatively year -old power and the angle of radicals. The most shortcoming is the visible light ingredients, that is, there is a red storm, and the service life is short. If every day is 10 hours, it can only be used for more than one year. In order to improve the life of thermal radiation infrared light, the light control switch circuit must be used to reduce the time. In addition, the delayed switch circuit has also increased to prevent the interference of the environmental light. The second is the infrared LED lamp beads composed of semiconductor gallium arsenidal gel diode array. Its optical output reaches 800MW -000MW, and its luminous semi-power angle is within a range of 10-160 . Because the infrared LED lamp beads are small in size, they can be uniformly shined in the room, and their life span is 50,000 hours. Anyone, pay attention to the following points when choosing an infrared LED light source. A. When the infrared launch pipe distance is selected, there should be a difference in the infrared LED light source, and pay special attention to the gap between the nominal distance and the actual radiation distance. Because the visual distance of some production plants is every night, so actual testing should be performed when the infrared light radiation distance is selected, and there must be sufficient waste to make the illumination of the viewing scenes reliably reliable. B. The light source of the constant current drive should be used because the infrared LED lamp bead is a constant current drive component. Therefore, in order to connect the luminous intensity, the light source driven by constant currents must be selected. C. You need to choose a light source with good heat dissipation because the light emitting tube has the problem of heat and heat dissipation, especially the light source that is far away from the light source to heat the heat. --- The article comes from LED lamp beads, please indicate Tongjia (China) www.tongjialed.com
