A safe and high-brightness LED lamp consists of a lampshade, a bulb mounting base, an LED module and a circuit board. The lampshade and bulb mounting base construct an inner space, which is allowable to store said LED module; the LED module consists of a heat-radiating block, an LED lamp panel and a reflective wall, where such LED lamp panel can be flat nestled up against the heat-radiating block at one end.
