摘要：The present invention relates to a lighting device for a button, in which light incident into a light guide is prevented from leaking to a spacing clearance between a button unit and a light guide by a reflection layer, thereby enabling a lighting through the light guide to shine cleanly and uniformly to the outside.

主权项：1. A lighting device for a button, the device comprising: a front panel; a push type button unit mounted on the front panel; a light guide placed on the circumference of the button unit and configured to radiate light incident through the rear to the front; and a light source unit placed at the rear of the light guide and configured to make light be incident into the rear of the light guide, wherein the button unit and the light guide are spaced apart from each other, the light guide includes: an incident unit formed at the rear of the light guide and configured to receive light incident through the light source unit; a radiation unit formed at the front of the light guide and configured to radiate the light incident through the incident unit to the outside; and a reflection layer plated onto the surface of a remaining lateral portion other than the incident unit and the radiation unit to reflect the light, and the light incident into the light guide is prevented from leaking to a spacing space between the button unit and the light guide by the reflection layer.
