Abstract
The utility model relates to an infrared camera for solving the problem of that the transmission film of the prior infrared camera reflects a part of infrared back to the camera lens so as to affect the shooting effect. The transmission film of the infrared camera of the utility model is divided into a first transmission film for protecting the infrared light and a second transmission film especially for protecting the camera lens; the first transmission film is provided with a camera hole, the taking lens comprises a non-translucent sleeve with a front opening and the light sensation components which are positioned inside the sleeve; the light sensation components are separated from the infrared by the sleeve, and which is extended to the first camera hole, the second tranmission film is positioned at the front-end opening of the sleeve. The structure can insure the transmission film that can not reflect the infrated back to the light sensation components, by which the shooting effect of the infrared camera can be enhanced further.

Be illustrated in figure 1 as the structural representation sketch of a traditional infrared video camera; this is one and simply analyses and observe design sketch; as can be seen from the figure; its middle shell 101 front ends are provided with opening; a plurality of infrared lamps 103 are housed on the circuit board 102 in housing; at the center of these infrared lamps are taking lenss 104, at the opening part of housing the light transmission piece 106 that shields are housed, and this light transmission piece is generally glass.This thermal camera integrates infrared illumination and shoot function, and is convenient and practical.
But, in this thermal camera, owing to the infrared light that each infrared lamp sent also penetrates not all vertically upward, after some infrared light wherein is mapped on the light transmission piece 106, can produce some reflections and enter taking lens 104, thereby can influence shooting effect; May occur the infrared light that subject reflects when serious and be weaker than the infrared light that light transmission piece 106 reflects on the contrary, cause the serious distortion of photographic images.
The utility model content
At the above-mentioned defective of prior art, the utility model will solve that light transmission piece in the existing thermal camera can be returned taking lens with the part infrared light reflection and the problem that influences shooting effect.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of thermal camera, comprise that front end is provided with the housing of opening; Openend in described housing is equipped with one or more infrared lamps, and the infrared shooting camera lens is housed; The light transmission piece that shields is housed at described opening part; Wherein, described light transmission piece comprises first light transmission piece that is exclusively used in the described infrared lamp of protection, is provided with camera aperture on described first light transmission piece; Described taking lens comprises that front end is provided with the non-printing opacity sleeve of opening, and is contained in the photosensory assembly in the described sleeve; Described sleeve will separate between described photosensory assembly and the infrared lamp, and extends to the camera aperture place of described first light transmission piece always.
In the utility model, described light transmission piece preferably also comprises second light transmission piece that is loaded on described barrel forward end opening part, is exclusively used in the described taking lens of protection.
In the utility model, preferably make described taking lens be positioned at the center, a plurality of infrared lamps are distributed in around it; Correspondingly, described camera aperture is located at the center of described first light transmission piece.
In the utility model, described sleeve can comprise the darkening ring that is positioned at the described first light transmission piece front portion and be positioned at the clamp nut at the described first light transmission piece rear portion; The front end of described darkening ring is provided with flange, and the camera aperture of described first light transmission piece is stretched in the rear end; The front end sleeve of described clamp nut is contained in the rear end of described darkening ring; Described second light transmission piece is greater than described camera aperture, and is loaded between described first light transmission piece and the clamp nut.
In the utility model, preferably also comprise the front end housing of a hollow structure, described first light transmission piece is fixed in the front opening place of described housing by described front end housing.
In the utility model, be preferably between the described front end housing and first light transmission piece, between the flange of described darkening ring and first light transmission piece and between described second light transmission piece and first light transmission piece, a waterproof apron be housed respectively.
As shown from the above technical solution, in the utility model, the photosensory assembly of taking lens is contained in the non-printing opacity sleeve, this sleeve will separate between photosensory assembly and the infrared lamp, and extends to the camera aperture place of first light transmission piece always.This structure can guarantee that light transmission piece can be to the photosensory assembly reflects infrared light, thereby further promotes the shooting effect of thermal camera.
