[0017] The utility model will be further described below with reference to the drawings.

[0018] The utility model discloses an inner roof lamp for automobile, which comprises a decorative cover 1, an arc-shaped brilliant inner lens 2, a base 3, a connector 6 and an LED (not marked), a plurality of first clamping buckles (not shown) and second clamping buckles (not shown) are formed on the side wall of the decorative cover 1 at intervals, a first clamping groove (not shown) is formed on the arc-shaped brilliant inner lens 2 opposite to the first clamping buckle, and the arc-shaped brilliant inner lens 2 is installed and fixed in the space surrounded by the decorative cover 1 through cooperation of the first clamping buckle and the first clamping groove. A second clamping groove is formed on the base 3 opposite to the second clamping buckle, and the base 3 and the decorative cover 1 are installed together through cooperation of the second clamping buckle and the second clamping groove, so that the base 3 and the decorative cover 1 are located on opposite sides of the arc-shaped brilliant inner lens 2 respectively.

[0019] The printed circuit board PCBA 4 is installed on the surface of the base 3 facing the arc-shaped brilliant inner lens 2 by a screw 5, and a protruding part (not shown) extending away from the arc-shaped brilliant inner lens 2 is formed on the printed circuit board PCBA 4. An opening part (not shown) is formed on the base 3 for the protruding part to pass through, and the protruding part extends out of the base 3 after passing through the opening part. The connector 6 is electrically connected to the protruding part extending out of the base 3. The LED is installed on the surface of the printed circuit board PCBA 4 opposite to the connector 6,
