The utility model relates to a side luminous touch key backlight structure, which comprises a panel, a reflective ring, a circuit board, a touch key and an LED (
Light Emitting Diode) lamp group. The panel is provided with a plurality of touch control areas, the touch control areas are provided with light-transmitting areas, the light-reflecting rings are arranged on the back surface of the panel, the plurality of light-reflecting rings are arranged, and the light-reflecting rings are in one-to-one correspondence with the touch control areas; the circuit board is detachably arranged on the back face of the panel, the touch keys are arranged on the circuit board and electrically connected with the circuit board, the touch keys correspond to the touch control areas in a one-to-one mode, the
LED lamp sets are electrically connected with the circuit board and correspond to the touch control areas in a one-to-one mode, each
LED lamp set comprises a plurality of
LED lamp beads, and the LED lamp beads are electrically connected with the circuit board and correspond to the touch control areas in a one-to-one mode. The LED lamp beads are arranged on the
peripheral side of the touch key in a surrounding mode and embedded in the inner side of the reflective ring. Light rays can be uniformly reflected and displayed on the front face of the panel, and the uniform backlight effect of the panel is achieved.
