摘要:
A unitary lead frame assembly having a plurality of lead frame sets each comprises a first lead frame unit. The first lead frame unit has a pair of first and second frame portions extending along a first direction and spaced apart from each other along a second direction different from the first direction. The lead frame set further comprises at least two second lead frame units disposed between the first and second frame portions and spaced apart from each other along the second direction. Each of the second lead frame units cooperates with the first lead frame unit to define at least one first die-bonding area therebetween.
摘要:
A light emitting diode (LED) module includes a lead frame having a number (N) of conducting arms spaced apart from each other, where N≧3, and at least one LED die mounted on one of any two neighbor conducting arms. Any two neighbor conducting arms are electrically coupled each other.

A light emitting diode (LED) includes an LED chip, a substrate structure, a fluorescence layer, and a lens. The substrate structure includes a cavity. The fluorescence layer covers on the LED chip and is configured in the cavity and covering the LED chip. The lens is installed on the substrate structure. The lens includes a curved lateral wall, a plane at the top, and a conical concave portion at the top center.
摘要:
The present invention relates to a package structure for light-emitting diodes (LEDs). The package structure includes a substrate, a heat-dissipating structure disposed on the substrate, and a plurality of LED chips uniformly disposed on the heat-dissipating structure. The heat-dissipating structure has a central portion and at least one peripheral portion surrounding thereof. The central portion is capable of dissipating more heat than the peripheral portion. Thus, the temperature difference between the LED chips disposed on the central portion and the LED chips disposed on the peripheral portion can be reduced.
