Patent ID: 8773612

Claim:
A light emitting module comprising: a module substrate; a metal reflective layer which is laminated on module substrate and has a light reflecting surface: a light emitting diode string comprising a plurality of light emitting diode elements, each of the light emitting diode elements comprising an anode element electrode and a cathode element electrode and having a rectangular shape that extends in a direction along which the element electrodes are aligned, and a plurality of bonding wires that electrically connect the light emitting diode elements adjacent to each other in series, the light emitting diode elements being fixed to the module substrate; a plurality of translucent die bond materials interposed between the plurality of light emitting diode elements and the light reflecting surface, the plurality of translucent die bond materials bonding the plurality of light emitting diode elements to the metal reflective layer; and a translucent sealing member laminated on the module substrate and configured to seal the light emitting diode string, wherein: the light emitting diode elements are arranged at intervals in a direction crossing the direction along which the element electrodes are aligned; the element electrodes having the same polarity are aligned to be adjacent to each other in an arrangement direction of the light emitting diode elements between the light emitting diode elements adjacent to each other; each bonding wire is obliquely wired with respect to the arrangement direction of the light emitting diode elements to connect the element electrodes having different polarities of the light emitting diode elements adjacent to each other; the plurality of translucent die bond materials are made of a resin material having lower gas permeability than a gas permeability of the sealing member; the plurality of translucent die bond materials protrude around the plurality of light emitting diode elements on the metal reflective layer; and peripheral portions of the plurality of translucent die bond materials are partially connected to one another.
