Abstract

The present invention relates to a resin molded optical lens. The infrared ray for detecting object surface is assembled on a lens support section of the optical lens composed of resin and shaped size of the lens section, the shape and size of the lens section are limited in design because alive condition of such as injection molding. Resin molded product independently separated as infrared ray assembling lens section configured upper side and a support section mounted onto the an electrothermic detector is formed, the light assembling lens section and the support section are integrated into the optical lens after ultrasonic deposition. Further, according to the construction design of the infrared ray detection device, the upper side light assembling lens is changed, adjusted to be various lens having various infrared ray detection zones, thereby easily selecting separation or division of the infrared ray zones.

Description

technical field

[0001] The present invention relates to a resin-molded optical lens for converging infrared rays from a human body to an infrared light receiving element included in a pyroelectric infrared detector mounted on a human body detection device. Background technique

[0002] An infrared detection device using a pyroelectric infrared detector for the purpose of human body detection, etc., uses an optical lens that converges the emitted infrared rays from the detection target area to the infrared light receiving element arranged inside the pyroelectric infrared detector. The position is set in a manner consistent with that of the above-mentioned pyroelectric infrared detector, thereby constructing a design-divided infrared detection area. The above-mentioned optical lens generally uses a resin material made of an infrared-transmitting material. For example, when a certain range of detection object surface is divided into a plurality of infrared detection areas, it i...
