Problems solved by technology

At present, there are two commonly used infrared lighting schemes: one is to turn on the corresponding infrared lights at different monitoring distances and viewing angles by combining several sets of infrared lights with different angles. This scheme cannot completely cover all distances and viewing angles, and The use of multiple sets of infr

Abstract

The invention discloses a searchlighting angle synchronously followed energy-saving infrared lighting system, which belongs to the field of optical mechanical and electronic integration and relates to an infrared lighting system used in the field of safety protection and monitoring. The system comprises an angle variable lens, an infrared light source, a stepper motor, a photosensitive resistor, a photocoupling switch, a radiating block and a control circuit board. In the system, a single infrared light-emitting diode (LED) with high light-emitting efficiency is matched with a dual-component zoom light-gathering lens, so that the synchronous following continuous variation between an infrared searchlighting angle and a camera zoom lens visual angle is realized, and the variation range of the searchlighting angle is between 60 and 3 degrees; and the system is an energy-saving infrared lighting system.

Description

technical field [0001] The patented technology belongs to the field of optomechanical integration, and relates to an infrared lighting system used in the field of security monitoring, in particular to an energy-saving infrared lighting system that follows the search angle synchronously. technical background [0002] With the continuous improvement of people's requirements for security night monitoring, we urgently need a more complete night infrared lighting system, which can meet the infrared lighting requirements of long and short distances, different viewing angles, and constantly changing monitoring conditions. At present, there are two commonly used infrared lighting schemes: one is to turn on the corresponding infrared lights at different monitoring distances and viewing angles by combining several sets of infrared lights with different angles. This scheme cannot completely cover all distances and viewing angles, and The use of multiple sets of infrared lamps has probl...
