Claim:
1. A light emitting device comprising: a submount; a flip chip type light emitting element having a first electrode and a second electrode oriented toward a bottom surface of a package, the light emitting element being mounted on the submount; a lead electrically connected to the light emitting element through a via provided in the submount, wherein the via is an opening in the submount; and a transparent resin layer and a phosphor layer coated on the light emitting element, wherein the light emitting device receives a driving bias from a bias generator and emits white light using a first light from the light emitting element and a second light from the phosphor layer, wherein a color temperature of the white light is varied by adjusting a level of the driving bias, wherein the light emitting element emits blue light, and wherein the phosphor layer includes a yellow phosphor which partially wavelength-converts the blue light from the light emitting element to emit yellow light and a red phosphor which partially wavelength-converts the blue light to emit red light, or a green phosphor which partially wavelength-converts the blue light to emit green light and a red phosphor which partially wavelength-converts the blue light to emit red light.
