Infrared lamps are the abbreviation of night vision monitoring of infrared lights. It is a light equipment that cooperates with the surveillance camera to collect images at night.The wavelength emitted by infrared lamps is 850nm and 940nm2, all of which are invisible light and have the characteristics of hidden and energy -saving. In the past 10 years, they have been widely used in the field of security monitoring.
Infrared lamp circuit
The circuit switch of the infrared lamp plate is a simple optical control switch. This optical control circuit is not complicated. It mainly controls the circuit to open and close the circuit through the resistance value of the light -sensitive resistance.The light -sensitive resistance is made of a special light -sensitive material. This resistor is particularly sensitive to light. When there is no light irradiation, its resistance value is small. When the light is illuminated, its resistance value will increase rapidly, making the current smooth.By lighting up the LED infrared light.
The wavelength of infrared lamp
The wavelength of infrared light is 830-950nm.The shining power of the infrared light is fixed. If the angle of light is large, it will naturally sacrifice the illumination distance. On the contrary, if the lighting distance is guaranteed, the angle will be sacrificed!The angle of choosing infrared lights is a very important issue.Using large -angle infrared lights with small angle lens, there is a waste of light.
Infrared lamp specification
Infrared light power
The power of infrared lights is generally 1.8 volt 600 mAh.
The role of infrared lamps
Infrared rays are generally used to heat.Selection and use of infrared lamps: The most important problem for the choice of infrared lights is the complete set of infrared lights and cameras, lens, protective cover, power supply power supply.Some people have bought cameras, lenses, protectives, power sources, and even considering buying infrared lights after installation. This is incorrect. When designing the plan, you should consider all equipment when designing the plan.Depending on the supervision and control system project, design.
