Title:
LIGHT-EMITTING DEVICE PACKAGE AND VEHICULAR LIGHT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2016/190706
Kind Code:
A1
Abstract:
A light-emitting device package according to an embodiment of the present invention comprises: a thermally conductive substrate provided with at least two mounting areas on which chips are mounted, and at least one bent area; a light-emitting device module comprising a light-emitting device arranged on one side of the mounting area; and a driving device module comprising a driving unit arranged on the other side, opposite to the one side, of the mounting area. The light-emitting device package according to an embodiment of the present invention has superb heat-dissipating characteristic since the light-emitting device module and driving device module are directly attached to the thermally conductive substrate, which is a heat sink, and the degree of freedom for design is significantly increased since the LED array module (LAM) and LED drive module (LDM) are integrated on both sides of a single substrate. Furthermore, a conventional heat sink, having a plurality of LED chips, an IC, a resistance chip and the like mounted thereon and provided with a cooling fin on the bottom, necessitated a large printed circuit board (PCB), whereas the embodiment of the present invention does not have a separate cooling fin, and resolves the issue of increased product cost stemming from additional processing cost by having the LAM and LDM disposed on the top and bottom, respectively, of the heat sink, and provides increased degree of freedom with respect to space in a device since the LAM and LDM are integrally disposed.
