Abstract:
1. A flip chip type LED lighting device manufacturing method comprising the steps of: providing a strip, said strip comprising a plurality of strip elements, said strip elements having a respective metal lead frame respectively electrically connected to one another, wherein each strip element comprises a depression on the bottom of each strip element; providing a submount and a plurality of flip chip LEDs (light emitting diodes) installed on said submount; forming a metal bonding layer between said strip element and said submount to bond said submount to said strip element to form a lighting structure, wherein the submount is bonded under the strip element and accommodated by the depression of the strip element; cutting the lighting structure thus obtained into individual flip chip type LED lighting devices based on each said strip element; and bonding a heat conducting/dissipating member to the submount of each said individual flip chip type LED lighting device, wherein said heat conducting/dissipating member is bonded to the bottom of said submount by means of a thermal interface material.
