Abstract
The invention relates to a camera, and provides a high-efficient infrared light harvesting device which is simple in structure, high in infrared utilization rate and good in imaging quality and matched with the infrared camera. The high-efficient infrared light harvesting device comprises an infrared light source which is arranged in a machine body, wherein a non-spherical lens is arranged between the infrared light source and an illuminating surface in the machine body, and the non-spherical lens is arranged in front of the infrared light source, so that the elliptical infrared emitted by the infrared light source is projected to the illuminating surface.
Description
Technical field
The present invention relates to video camera, particularly a kind of efficient infrared light collecting device that is matched with thermal camera.
Background technology
Thermal camera is exactly by the comprehensive all-in-one-piece watch-dog such as CCTV camera, protective cover, infrared lamp, power supply heat-sink unit in fact.In supervision control engineering, the most frequently used thermal camera is active infrared at present, by LED, send infrared ray, utilize CCD or CMOS can experience the spectral characteristic (can experience visible ray, also can experience infrared light) of infrared light, coordinate infrared lamp to carry out night vision imaging as " light source ".The infrared light that thermal camera projects is all round to shadow surface conventionally, and the imaging target surface of video camera is rectangle, corresponding to the object space imaging in rectangle frame, at infrared light during as light source, the circular infrared light projecting has just only utilized the video camera imaging target surface of circular infrared light rectangle in shadow surface to shadow surface, make the shadow surface of the circular infrared light that projects cause waste, infrared light utilance is low, and then has affected image quality.
Summary of the invention
Therefore, for above-mentioned problem, the present invention propose a kind of simple in structure, infrared light utilance is high, the efficient infrared light collecting device that is matched with thermal camera of good imaging quality.
For realizing above-mentioned technical problem, the solution that the present invention takes is: a kind of efficient infrared light collecting device that is matched with thermal camera, comprise the infrared light supply of being located in fuselage, in described fuselage, between infrared light supply and shadow surface, be provided with non-spherical lens, this non-spherical lens is located at infrared light supply the place ahead and is made infrared light supply project oval-shaped infrared light to shadow surface.
Further, described non-spherical lens is simultaneously curved surface, and definition be take horizontal direction radius that the origin of coordinates is point of contact and intersected lap as curved surface as 50mm spheroid and vertical direction radius as 30mm spheroid, and the curved surface of described non-spherical lens is towards infrared light supply.
Further, the curved surface external diameter diameter of described non-spherical lens is 15mm, and center of surface thickness is 3.2mm.
Further, described non-spherical lens is to be made with acrylic material.
By adopting aforementioned techniques scheme, the invention has the beneficial effects as follows: by non-spherical lens being set in the place ahead, infrared lamp source, make infrared light supply project oval-shaped infrared light to shadow surface, with traditional circular infrared light project shadow surface compare greatly improved infrared light utilance high, improved image quality, can wide popularization and application.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention theory structure schematic diagram;
Fig. 2 is the aspheric lens structures schematic diagram of the embodiment of the present invention.
Embodiment
Now the present invention is further described with specific embodiment by reference to the accompanying drawings.
With reference to figure 1 and Fig. 2, the disclosed efficient infrared light collecting device that is matched with thermal camera of the embodiment of the present invention, comprise the infrared light supply 2 of being located in fuselage 1, in described fuselage 1, between infrared light supply 2 and shadow surface 3, be provided with non-spherical lens 4, this non-spherical lens 4 is located at infrared light supply 2 the place aheads and is made infrared light supply 2 project oval-shaped infrared light to shadow surface 3, described non-spherical lens 4 one sides are curved surface, definition be take horizontal direction radius that the origin of coordinates is point of contact and is intersected lap as curved surface as 50mm spheroid and vertical direction radius as 30mm spheroid, the curved surface of described non-spherical lens 4 is towards infrared light supply 2, the curved surface external diameter diameter of described non-spherical lens 4 is 15mm, center of surface thickness is 3.2mm, described non-spherical lens 4 is to be made with acrylic material.
In the present invention, the curved surface of non-spherical lens can also be that other different spheroids intersect other curved surface overlapping, the specification that its size also can be different according to the big or small type configure of thermal camera.
Through many experiments, measure, existing infrared light supply is incident upon to 300mm place, the place ahead to be placed on the projection screen surface of 480 X360mm and carries out analogue measurement, 10000 light altogether, LED power 1W, existing circular Infrared irradiation face ray-collecting to 3967 (efficiency 40%), and oval Infrared irradiation face ray-collecting to 4552 of the present invention (efficiency 46%), rectangle is subject to face light intensity to increase by 15%, has greatly improved infrared light utilance.
The present invention is by arranging non-spherical lens in the place ahead, infrared lamp source, make infrared light supply project oval-shaped infrared light to shadow surface, with traditional circular infrared light project shadow surface compare greatly improved infrared light utilance high, improved image quality, can wide popularization and application.
Although specifically show and introduced the present invention in conjunction with preferred embodiment, within not departing from the category of the present invention that appended claims limits, can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
