The invention relates to a brake lamp for an automobile, and belongs to the technical field of brake lamps, the brake lamp comprises a control module, a light source, a spreadlight lens and a semi-light-guide strip, the spreadlight lens and the semi-light-guide strip are sequentially arranged in the light path direction of the light source, and the spreadlight lens is used for diverging light emitted from the light source; a polarizing plate is arranged between the spreadlight lens and the semi-light-guide strip, the polarizing plate is electrically connected with a control module, the control module adjusts the divergence degree of light emitted from the spreadlight lens by instructing the polarizing plate to rotate, and the control module is used for judging whether the vehicle speed exceeds a threshold value or not. The control module reduces the divergence degree of the spreadlight lens to the light emitted by the light source when the vehicle speed exceeds a threshold value, and improves the divergence degree of the spreadlight lens to the light emitted by the light source when the vehicle speed is lower than the threshold value.
本发明涉及一种汽车用制动灯,属于制动灯技术领域,包括控制模块、光源、偏光透镜和半导光条,所述偏光透镜和半导光条依次沿光源的光路方向设置,所述偏光透镜用于发散从光源射出的光;所述偏光透镜和半导光条之间设置有偏光板,所述偏光板与控制模块电连接,所述控制模块通过指令偏光板旋转调整从偏光透镜射出光的发散程度,所述控制模块用于判断车速是否超过阈值,所述控制模块在车速超过阈值时降低偏光透镜对光源射出光的发散程度,所述控制模块在车速低于阈值时提高偏光透镜对光源射出光的发散程度。
