<P>PROBLEM TO BE SOLVED: To provide a light emission diode lighting device in which color mixture of outgoing blue light and white light is suppressed. <P>SOLUTION: A light emission diode lighting device comprises: a support having a mount face on which a blue light source region and a white light source region are sequentially defined in a longer direction; a blue light source disposed in the blue light region and having a light emission diode for emitting blue light; a white light source disposed in the white light source region and having a light emission diode for emitting white light; and a lighting cover disposed on the support so as to cover the mount face, in which a plurality of grooves 301 extending in the longer direction and having a wave-shaped cross section along a shorter direction are formed in an incident face opposite to the mount face. In this lighting device, light emitted from the blue light source and the white light source enters the lighting cover from the incident face and the incident light penetrates the lighting cover and is outputted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
