Background technology
The infrared inductor of Chu Shouing in the market, as infrared induction lamp or the antitheft monitor of infrared ray etc., the multiple-point focusing sheet of its use mostly is the focal region of diffusion type permutation and combination and is the stripe-shape plane resin film of the caustic surfaces that two row arrange for which is provided with by several concentric refraction arc surfaces, wherein each focal region all is equivalent to form by the multi-disc magnifier is superimposed, and for cooperating the installation of stripe-shape plane multiple-point focusing sheet, the fixed frame that existing antitheft monitor must be established a specific arc monitoring window and an arc hollow out at its front end is with fixing film and make it be the arcuation arch to improve its focusing effect, the alarm of this structure monitoring net monitoring range angle that not only it constituted only has 110 degree, so that night, the robber was easy to invade part often in its position, two avris dead angles that can't monitor, and its complex structure, volume is big, install very loaded down with trivial details, the production cost height.A kind of multifocal lens structure with the super wide-angle monitoring range of 180 degree is disclosed although the patent No. is the Chinese patent of ZL95213810, it adopts the left and right sides that original bar shaped is focused on the sheet outermost to be made as independently and its focus is positioned at the focal region of edge line central authorities, the fixed frame adapting device that again film is imposed appropriate deflection arc rate and specific arc monitoring window and arc hollow out during installation is on antitheft monitor, thereby enlarged the monitoring range of its monitor to a certain extent, but the scope that its weak point is it to be responded to only is a left side, the umbrella of right looses regional, and on, following direction is all blocked by shell, so its scope that can not respond to still less, the dead angle still is more, and can only hang on the wall and use, can not when inhaling the top, use, and loaded down with trivial details problem is installed in same existence.
Summary of the invention
The purpose of this utility model is to solve the problem of above-mentioned existence, provide a kind of infrared inductor that both can make to carry out comprehensive monitoring and effectively enlarge its induction range, and simple in structure again, easy for installation, the usable range multiple-point focusing sheet used of infrared inductor widely.
The technical solution of the utility model is achieved in that
The multiple-point focusing sheet that infrared inductor described in the utility model is used is characterized in comprising semisphere resin glue cup and is arranged at least one row on this resin glue cup inside surface being diffusion type by several concentric cambered surfaces and arranging the caustic surface that the focal region with refraction, reflection, optically focused effect form rearranges continuously.
Wherein, the arrangement mode of above-mentioned each caustic surface on above-mentioned resin glue cup inside surface can be varied, and as can being that above-mentioned each caustic surface is located on the inside surface of above-mentioned housing in regular turn, and the concentric cambered surface of its each focal region all be by gradually close inward shape outward and arranges; Also can be that each caustic surface is arranged in parallel and becomes " ten " word shape to be arranged on the inner bottom part of above-mentioned resin glue cup, and the concentric refraction arc surface in its each focal region be even shape and arrange or the like.
For making the utility model easy for installation, described resin glue cup is provided with can be with monitoring window adapting device on the inductor and positioning means for positioning.The structure of above-mentioned locating device also can be varied, can be for being equipped with the outer flanging of the band mounting hole on this resin glue cup openend as above-mentioned locating device; Above-mentioned locating device can also be for being arranged at the card ear on these resin glue cup openend both sides.
The utility model is owing to adopt by semisphere resin glue cup and be arranged at least one row on this resin glue cup inside surface and be diffusion type by several concentric refraction arc surfaces and arrange the focusing chip architecture that caustic surface that the focal region that forms rearranges is continuously formed, thereby make the utility model in the process of using, can wholely protrude from outside the infrared inductor housing, and the infra-red range that the focusing effect that infrared ray is produced by focal region on it can be responded to this inductor enlarges greatly, the induction of 180 degree scopes about infrared inductor can be carried out, but also can make it can carry out the induction of 180 degree scopes up and down, reduced the existence at sensing dead angle effectively, and it is simple in structure, installs simple and easy, production cost is low.And the infrared inductor that uses this focusing sheet both can hang on the wall and use, and also can use when inhaling the top, and usable range is extensive, and the utility model is specially adapted on home-use sense light or the antitheft monitor.
Below in conjunction with accompanying drawing the utility model is further described.
