Abstract

An illumination device is provided. The illumination device includes a heat sink coupled to a housing, and the heat sink includes at least one heat dissipation pin extending from an external surface of the housing. Vent holes that expose the external surface of the housing, an inside of the housing, or an inside of the illumination device to external air are formed on a side of the at least one heat dissipation pin. An upper edge of the housing and the heat sink may be spaced apart from each other, and the spaced region may include a gap that exposes the illumination device or the inside of the housing.

Description

[0001] This application claims the rights of Korean patent application No. 10-2014-0182550 filed at the Korean Intellectual Property Office on December 17, 2014, and the disclosure of the Korean patent application is incorporated herein by reference in its entirety. Technical field [0002] The present disclosure relates to a lighting device, and more particularly, to a lighting device in which at least a part of the upper edge of its housing is exposed. Background technique [0003] Lighting devices are usually used to ensure clear vision in dark places, express visual effects of advertisements, or present aesthetic purposes. The light source of the lighting device may include an incandescent lamp, a fluorescent lamp or a halogen lamp. In recent years, light emitting diodes (LEDs) are often used as light sources. [0004] The LED used in the lighting device can realize various colors of light by changing compound semiconductor materials such as GaAs, AlGaAs, GaN, and InGaInP. LED...
