LED LIGHT BAR, PLANAR LIGHT SOURCE INCLUDING THE SAME, AND METHOD FOR MANUFACTURING THE PLANAR LIGHT SOURCE

摘要

A light-emitting diode (LED) light bar (620) comprises a light bar substrate (660), at least one bonding layer (615), at least one LED chip (614), at least one first wire (681), at least one second wire (682) and at least one package unit (671). The light bar substrate (660) defines a receiving space (674) and comprises an intermediate metal plate (663), a first side metal plate (661) and a second side metal plate (662), which are insulated from each other. The at least one LED chip (614) is bonded to a light-reflecting surface of the intermediate metal plate (663) by the at least one bonding layer (615). The at least one first wire (681) and the at least one second wire (682) are coupled between positive and negative terminals of the at least one LED chip (614) and the first side metal plate (661) and the second side metal plate (662), respectively. The at least one package unit (671) packages the at least one LED chip (614).
