Description

An infrared lighting device

technical field

The utility model belongs to the technical field of infrared lighting, in particular to an infrared lighting device for night vision monitoring.

Background technique

At present, the application range of monitoring equipment is becoming more and more extensive, and there is also a strong demand for night monitoring effects. The conventional method is to use visible light to illuminate, but visible light has the disadvantages of being unable to conceal and easily exposing the monitoring target, so it is rarely used; at present, the commonly used night vision monitoring for concealment is to use infrared supplementary light technology, which emits infrared lights that cannot be seen by the human eye but are invisible to the camera. Recognizable infrared light can realize the effect of night surveillance. With the continuous development and deepening of monitoring technology and demand, simple supplementary light can no longer meet the needs. For example, the single LED commonly used at present has the problems of low power and low electro-optical utilization rate. To achieve a satisfactory supplementary light effect requires a lot of high power and takes up a lot of space. Another type of array infrared lamp that is emerging is that many lamp elements are highly concentrated in a hole with a lens, which has a serious problem of wasting light energy. At the same time, the heat generated by the highly concentrated lamp elements cannot be dissipated in time. Affect the life of the infrared lamp.
