Abstract
A light emitting diode assembly with low thermal resistance comprises an LED, a circuit board and a heat-dissipating substrate. The LED has a die mounted on a heat-dissipating plate and pads connected to a printed circuit board. The LED is mounted on a circuit board and a heat-dissipating substrate, whereby the thermal resistance of the LED assembly can be advantageously reduced to enhance the performance of the LED assembly.
Claims7
A light emitting diode assembly with low thermal resistance, comprising:
- a light emitting diode having a heat-dissipating plate having a central recess formed therein, a die positioned in contact with said heat dissipating plate within said recess, a printed circuit board positioned atop said heat dissipating plate and having a central aperture formed therein and circumscribing said die, and a protective encapsulation formed atop the die;
- a heat-dissipating structure connected to the heat-dissipating plate;
- and
- a circuit board connected to the heat-dissipating substrate, said circuit board having a central opening formed therein and circumscribing said heat dissipating plate.
