First Claim
Patent Images
1. An insect trap comprising:
- a duct including a suction fan therein;
a UV LED lamp disposed in an air inlet portion of the duct, and including a printed circuit board (PCB) that has a UV LED chip; and
a trapping portion provided in an air outlet portion of the duct,wherein the UV LED chip includes;
an n-type contact layer;
a p-type contact layer; and
an active region located between the n-type contact layer and the p-type contact layer and including barrier layers including a first barrier layer located closest to the n-type contact layer,wherein the barrier layers include AlInGaN or AlGaN, andwherein the UV LED chip is positioned on a first side of the PCB and a second side of the PCB that is opposite to the first side of the PCB serves to dissipate heat generated from the UV LED chip, and wherein the insect trap further includes a transparent housing located at the first side of the PCB extending along an entire length of the PCB and including a material that allows UV light produced by the UV LED lamp to pass therethrough.

Abstract
The present disclosure relates to an insect trap using an ultraviolet light-emitting diode (UV LED) lamp, and more particularly, to an insect trap using, in place of a conventional UV light source lamp, a UV LED lamp that significantly increases the insect trapping efficiency. The insect trap according to the present disclosure includes: a UV LED lamp disposed in an air inlet portion of the duct, and including a printed circuit board (PCB) that has a UV LED chip mounted thereon; an installing portion for installing the UV LED lamp on; and a trapping portion provided near the installing portion.
