Abstract

The invention discloses a zoom type infrared lamp and control method as well as an infrared camera, wherein the zoom type infrared lamp comprises a controller, a motor, an infrared lamp camera lens and a parallel infrared generating device which are sequentially connected, wherein the parallel infrared generating device is connected with the controller; the parallel infrared generating device is used for generating parallel infrared light; the infrared lamp camera lens comprises a first convex lens and a second convex lens, wherein the position of one convex lens is fixed, and the position ofthe other convex lens is adjustable, and the first convex lens and the second convex lens are sequentially arranged on a main optical axis at the direction of propagation of an infrared light way; and the controller is used for receiving the current zooming rate information of the infrared camera, and driving the first convex lens/ the second convex lens to move from left to right on the main optical axis to adjust the divergence angle of the infrared light ray according to the zooming rate information and the congruent relationship data information of the interval between the prestored zooming rate and the first convex lens as well as the second convex lens. By adopting the zoom type infrared lamp and the control method as well as the infrared camera provided by the invention, the divergence angle of the infrared light ray is simple and convenient to control accurately, and thus the infrared light ray is uniform, and the picture quality of the camera can be improved.

Description

technical field [0001] The invention belongs to the technical field of night vision camera monitoring, and in particular relates to a zoom-type infrared lamp, a control method thereof, and an infrared camera. Background technique [0002] With the continuous development of video surveillance technology and the needs of social development, more and more infrared cameras are used in camera surveillance system engineering. Infrared cameras play a more prominent role in night monitoring. They are not only used in important departments such as treasury, oil depot, armory, library, cultural relics department, prison, etc., but also widely used in general monitoring systems. Infrared camera technology is divided into passive and active. Passive infrared camera technology uses any substance that has infrared radiation above absolute zero (-273°C). The higher the temperature of the object, the more infrared rays it radiates. This principle is used to make The most typical camera is...
