  • Publication number: 20230126937
    Abstract: A puddle lamp for a vehicle includes a light source unit including a plurality of light sources installed on a substrate to allow formation of a plurality of images on ground; a light condensing unit including a plurality of condensing lenses for condensing light generated from the plurality of light sources; an imaging unit for transmitting the light from the light condensing unit to form at least one of the plurality of images; and a holder disposed between the light source unit and the light condensing unit to fix positions of the light source unit and the light condensing unit. The holder includes a partition wall unit to allow the light generated from each of the plurality of light sources to be separated from one another and to proceed to the imaging unit.

  • Patent number: 8609242
    Abstract: The present invention relates to a non-flammable cushioning and sealing sheet and, more particularly to, a sheet having a sequential layered structure of an adhesive layer, a polyurethane layer, and a surface coating layer, the polyurethane layer containing melamine polyphosphate and diphenyl cresyl phosphate as a flame retardant. The present invention also relates to a method for preparing a non-flammable cushioning and sealing sheet that comprises: preparing a polyurethane layer containing melamine polyphosphate and diphenyl cresyl phosphate as a flame retardant; forming a adhesive layer on the one side of the polyurethane layer; and forming a surface coating layer on the other side of the polyurethane layer where the adhesive layer is not formed.
