LED lighting apparatus having separate wavelength conversion unit
First Claim
1. An LED lighting apparatus having a separate wavelength conversion unit, comprising:
- the wavelength conversion unit, including an optical component having a surface, and a wavelength conversion layer formed on the surface; and
at least one LED positioned such that the wavelength conversion layer can be excited thereby, and including a base, an LED chip mounted on the base, and a lens formed on the base and covering the LED chip.

Abstract
The present invention provides an LED lighting apparatus having a separate wavelength conversion unit, which comprises the wavelength conversion unit and an LED. The wavelength conversion unit has an optical component and a wavelength conversion layer. The LED may be such positioned that the wavelength conversion layer is excited thereby. By forming the wavelength conversion unit at a surface of the optical component, the process of the LED can be simplified and the yield can be improved. Further, the present invention contributes to extending the application scope of the LED lighting apparatus by separating the wavelength conversion unit from the LED, so as to achieve optically desired light beams with evenness.
