LED lamp, manufacturing method of the same, and LED caption panel thereof

The present invention relates to a LED lamp, manufacturing method of the same, and its LED caption panel, wherein the LED lamp comprises a set of lead frames, a column-like transparent package body, and a block-like light diffusion package body. The set of lead frames comprises at least two pins, and the top of one pin is formed with a crystal cup, and a LED die is configured within the crystal cup and connected to another pin with a lead. The transparent package body encapsulates the top of the set of lead frames to completely encapsulate the crystal cup and the LED die. The light diffusion package body is formed on the top surface of the transparent package body such that the emitted light of the LED lamp is concentrated on the top for diffusion after lighting up. Accordingly, when a plurality of LED lamps are arranged on a substrate to manufacture a LED caption panel for usage, the light source can be prevented from excessively concentrating during light-up or excessively attenuating, and the problem of no
