LIGHT EMITTING DIODE LAMP BAR AND MANUFACTURE METHOD THEREOF, LIGHT EMITTING DIODE LAMP TUBE

摘要

A light emitting diode lamp bar (102) includes a circuit board (110), a plurality of light emitting diodes (120), heat-conducting material (130), a heat-conducting insulating layer (140) and a heat-conducting plate (150). The circuit board (110) has the first surface (112) and the second surface (114) opposite to each other. The first surface (112) has a plurality of wafer configuring regions (115) arrayed to multiple rows, and at least one heat-dissipating through hole (116) is provided in each wafer configuring region (115). The light emitting diodes (120) are arranged at the wafer configuring regions (115) one to one. The heat-conducting material (130) is filled in the heat-dissipating through holes (116) and contacts the corresponding light emitting diode (120). The heat-conducting material (130) extending from the heat-dissipating through holes (116) in the same row's wafer configuring regions (115) is connected as a whole on the second surface (114). The heat-conducting plate (150) is pasted to the second surface (114), and the heat-conducting insulating layer (140) is configured between the heat-conducting plate (150) and the circuit board (110). The light emitting diode lamp bar (102) has good heat-dissipating effect. A manufacture method of the corresponding light emitting diode lamp bar (102) and a light emitting diode lamp tube (100) including the corresponding light emitting diode lamp bar (102) are also provided.
