Abstract: A LED chip is bonded on a large submount serving as a heat sink. The submount is punched out from a thin metal sheet together with two other sections of lead frames for the LED and held together with insulating material. The planar structure makes the package thin. A transparent lens may be mounted over the submount. More than one LED of same or different color can be mounted on the submount.

Abstract: A light emitting diode (LED) includes a LED chip, which can transfer electrical power to electric-magnetic wave. A set of lead frame is enclosed by electrical isolator material to form a cavity. An optics lens seats on top of the cavity and is bonded to said electrical isolator material. A submount to carry said LED chip is soldered or adhered to the lead frame and forms the electrical contact from said LED chip to lead frame. A high transparency material is utilized to enclosed the LED chip.

Abstract: A light emitting diode (LED) package is fabricated with protection circuit against static electricity. The protection circuit includes series connection of more than one Zener diodes which limit any voltage surge no higher than their breakdown voltage, and is connected in parallel with the LED chip. The breakdown voltage of the protection circuit in either direction is greater than the rated forward or reverse testing voltage. The series connection of the protection circuit can be made through printed circuit submount.
