    摘要: A method for manufacturing a lighting device includes the steps of: preparing a substrate having at least one lighting chip, a frame for surrounding the lighting chip, and a cover body for covering one side of the frame; bonding the frame and the substrate so that the lighting chip is located within a region surrounded by the frame; and bonding the cover body and the frame so that the cover body and the frame cooperatively define a receptacle to cover the lighting chip. A bonding force between the cover body and the frame is configured to be smaller than a bonding force between the frame and the substrate so that when the cover body is separated from the frame, the bonding between the frame and the substrate is not destroyed.
