Abstract
(EN)
The present invention relates to a directional infrared sensor using a pinhole phenomenon, wherein the directional infrared sensor is manufactured with a compact size and uses a pinhole phenomenon to increase the intensity of light irradiated to a sensing element while improving the directionality of the infrared sensor. To solve the above problems, the present invention provides a directional infrared sensor using a pinhole phenomenon comprising: a main body provided with first and second sensing elements which are arranged to be separated from each other in parallel on the front surface of the main body; a casing having a hollow hole provided in the forward and backward direction, wherein the main body is inserted into the hollow hole such that the rear surface of the main body closes the rear end of the hollow hole and a cover plate closes the front end of the hollow hole; and a pinhole formed in the cover plate of the casing. The first sensing element outputs a wavelength value of infrared rays sensed from a heat dissipation body as a positive value or a negative value, and the second sensing element outputs a signal having a phase opposite to the first sensing element. The main body includes a field-effect transistor built therein, the field-effect transistor outputting a sensing signal (SEN) according to output signals of the first and second sensing elements.

Le capteur infrarouge directionnel utilisant un phénomène de trou d'épingle comprend : un corps principal comportant des premier et second éléments de détection qui sont agencés pour être séparés l'un de l'autre en parallèle sur la surface avant du corps principal; un boîtier ayant un trou creux fourni dans la direction avant et arrière, le corps principal étant inséré dans le trou creux de telle sorte que la surface arrière du corps principal ferme l'extrémité arrière du trou creux et une plaque de recouvrement ferme l'extrémité avant du trou creux; et un trou d'épingle formé dans la plaque de recouvrement du boîtier. Le premier élément de détection délivre une valeur de longueur d'onde de rayons infrarouges détectés à partir d'un corps de dissipation de chaleur sous la forme d'une valeur positive ou d'une valeur négative, et le second élément de détection délivre un signal ayant une phase opposée au premier élément de détection. Le corps principal contient un transistor à effet de champ, le transistor à effet de champ délivrant un signal de détection (SEN) en fonction des signaux de sortie des premier et second éléments de détection.
