The invention relates to the technical field of automotive interiors, in particular to an automotive instrument desk atmosphere lamp which comprises a lamp holder and a lamp strip, wherein one end ofthe lamp strip is inserted into the lamp holder; the lamp strip comprises a strip body; a plurality of cutting grooves are formed in the side, back on to an opening of a light shield, of the strip body, and the cutting grooves are formed in the direction perpendicular to the central axis of the strip body. A large amount of light rays generate total reflection on the inner walls of the cutting grooves, the reflected light rays enable the brightness of a section of the strip body corresponding to each cutting groove to be increased, the brightness of a dark position of the strip body is compensated, the brightness change of the strip body which is bright originally after the original bright position of the belt body is supplemented with reflected light (human eyes feel) is small, and therefore human eyes can feel that the brightness is uniform in the length direction of the lamp strip. Due to the fact that reflected light on the inner wall of each cutting groove can supplement light tothe corresponding section of the strip body, the density of the cutting grooves farther away from the lamp holder is larger, the light supplement density (intensity) farther away from the lamp holderis larger, and the brightness of the strip body in the length direction can be uniform.

    本发明涉及汽车内饰的技术领域,尤其是涉及一种汽车仪表台氛围灯,包括灯头和灯带,灯带的一端插入灯头内,所述灯带包括带体,带体上背对遮光罩开口的一侧设有若干割槽,割槽沿垂直于带体中轴线的方向设置。大量光线在割槽的内壁处产生全反射,反射光线使对应于每个割槽的一段带体亮度增加,弥补了带体较暗处的亮度,而带体原先较亮处补充反射光后(人眼感觉)亮度变化较小,所以在人眼能够感觉到灯带长度方向上亮度均匀;由于每个割槽内壁上的反射光都会向对应的一段带体补光,而距离灯头越远处的割槽密度越大,所以距离灯头越远处补光密度(强度)也越大,因此能够使带体长度方向上亮度均匀。
