A lighting module may be provided that includes a light emitting device module including at least one light emitting diode; and a heat sink radiating heat generated from the light emitting device module and including at least one partition wall formed on a base.

A lighting device and a gap member and a lens used in a lighting device. The lens may include a circular incident surface that has a furrow surface crossing a surface and prism surfaces formed at both sides of the furrow surface; and an exit surface that reflects and transmits light traveling inside through the incident surface to the outside. The gap member may include a ring-shaped reflective portion having a declined surface toward the center; and a ring-shaped wall extending downward coaxially with the reflective portion, and has a flat ring shape. The lighting device may include a substrate; a light emitting unit including a plurality of LEDs mounted on the substrate; a case body accommodating the light emitting unit; a lens disposed on the light emitting unit; a first waterproof ring disposed around the lens; and a case cover having an opening that exposes the lens, and combined with the case body and the first waterproof ring.

Gap member, lens and lighting device having the same

An illumination lens including a first part being free of prismatic patterns, a second part including prismatic patterns on both sides of the first part and configured to increase light distribution in the both sides of the first part, and a lens cover covering the first and second parts with the first and second parts being disposed on a substantially same plane under the lens cover.

Disclosed are a method for preparing a catalyst, which has excellent nitrogen oxide-removal performance and resistance over a wide temperature range, and the use of the catalyst. According to the disclosed method, the oxidation number and surface defects of the catalyst are changed by applying artificial high energy through mechanical ball milling during the preparation process of the catalyst, instead of applying the addition of a precious metal, the deformation of a support and the use of a co-catalyst in order to increase NOx removal activity, such that activation energy for inducing redox reactions can be decreased.
