Abstract
An LED device comprises a white LED device and a red LED device. The white LED device has a substrate, a blue LED mounted on the substrate for emitting blue light, a transparent resin covering the blue LED and including phosphor particles. The phosphor particle has a quality to convert blue light to white light, if the particle contacts with the blue light. The red LED device has a substrate, a red LED mounted on the substrate for emitting red light, and a transparent resin covering the red LED device is disposed so that emitted red light mixes with the white light emitted from the white LED device.
