The utility model provides a concealed LED flash lamp. The concealed LED flash lamp comprises a light guide plate, a circuit board and LED lamp beads fixed on the circuit board, wherein the LED lamp beads are mounted on one side surface of the light guide plate; a light-emitting surface of the light guide plate is a table top with a logo pattern; lattice points are distributed on a back surface opposite to the light-emitting surface of the light guide plate and are used for reflecting light. According to the concealed LED flash lamp, the required logo pattern is directly designed on the light-emitting surface of the light guide plate on which the lattice points are distributed, so that the product quality problem caused by bonding of a logo label can be solved. Meanwhile, the concealed LED flash lamp is applied to a logo of a mobile phone, so that a logo mark is more striking, a caller identification function can be realized, and the production cost of a product can be reduced.
