Solid state lighting component
View Patent ↗An LED component comprising an array of LED chips mounted on a planar surface of a submount with the LED chips capable of emitting light in response to an electrical signal. The LED chips comprise respective groups emitting at different colors of light, with each of the groups interconnected in a series circuit. A lens is included over the LED chips. Other embodiments can comprise thermal spreading structures included integral to the submount and arranged to dissipate heat from the LED chips.
1. A white emitting light emitting diode (LED) package comprising an LED chip array and an overmolded lens over said array having a diameter greater than 5 millimeters, wherein said lens has a diameter being approximately the same as or larger than the width of said array.
2. The LED package of claim 1 , wherein said lens has a diameter of approximately 11 millimeters.
3. The LED package of claim 1 , wherein said LED chip array comprises 26 LED chips, each of which emits light at one of a plurality of colors.
4. The LED package of claim 1 , wherein said lens comprises a hemispheric lens having a diameter of approximately 11 millimeters.
5. The LED package of claim 1 , wherein the focal point of said lens is located in or below the horizontal plane created by the emitting region of the LED chips.
6. The LED package of claim 1 , wherein said lens comprises an aggregate of multiple optical elements.
7. The LED package of claim 1 , wherein said lens comprises an essentially flat optically transparent element.
