Abstract
An LED bar module includes a lengthwise base and a number of LED chips. The lengthwise base includes a metal layer, a metal circuit layer, and an insulated layer between the metal layer and the metal circuit layer. The insulated layer has a groove in a central thereof to expose a part of the metal layer. The LED chips are placed in the groove and directly contact the exposed part of the metal layer. The metal circuit layer has two connecting portions electrically connecting with the LED chips. The LED chips are arranged in a line which is located between and juxtaposed with the two connecting portions of the metal circuit layer.
