The invention discloses a carpet lamp. The carpet lamp includes a light guiding support and a carpet lamp module; the light guiding support is located under a front floor plate and fixed on the frontfloor plate and an A-pillar reinforcement plate; the carpet lamp module is fixed in the light guiding support and projects a light image; the carpet lamp cannot be seen through the shielding of side walls under a head-up or overhead visual angles; the carpet lamp is close to front wheel covers but maintains safe intervals with the front wheel covers; the carpet lamp is located outside the workingarea of a jack and projects the light image to the rear side on the sides of a vehicle body; and the projected light image can cover the areas with lengths of 2,200 mm and widths of 280 mm on the sides of the vehicle body. Through the carpet lamp, the carpet lamp module can be installed at the vehicle floor plate area which cannot be seen at a normal visual angle, and distances from the front wheel covers can be reduced as much as possible in structure, so that lamp sets can be guaranteed to arrange at the front part of a vehicle as far as possible, and light effects can be ensured to start projecting from the front part of the vehicle as close as possible; and the avoiding of technological structures such as the jack can be simultaneously considered.
