Patent abstract

A white light source is obtained by converting short wavelength color light emitted from a light emitting diode (LED). The conversion is achieved by covering the LED chip with a fluorescent glue. The LED chip is mounted on a split substrate, and the outer ends of the substrate serve as terminals for the LED. A wall may be erected around the LED chip to contain the fluorescent glue, and another transparent glue may be used to cover the fluorescent glue for protection.
