Abstract
An LED device has a light emitting chip covered by a pre-formed fluorescent plate for emitting white light. The light emitting chip is located in a chip holder. The pre-formed fluorescent plate is positioned above the light emitting chip and supported by the chip holder. Transparent resin is used to seal the void formed between the chip holder and the pre-formed fluorescent plate. Because the thickness and flatness of the pre-formed fluorescent plate can be easily controlled, white light emitted from the LED device has high quality as well as good uniformity.
