The refractive index of the first lens is between 1.4 and 1.6, and the average curvature of the light-emitting surface of the first lens is between 1/36 (mm ^-1 ) and 1/43 (mm ^-1 ), when the incident light received by the first lens When it is the first light source with a light emitting angle of 120 degrees, the first lens has a light emitting angle within 70 degrees in the horizontal direction on the light emitting surface, and has a light emitting angle within 5 degrees in the vertical direction, and the size of the first lens in the short axis direction is not greater than 50 millimeter (mm), and the protruding height of the first lens on the light-emitting surface is not greater than 20 millimeters. When the light emitted by the second light source enters the second lens, the second lens has a light exit angle within 40 degrees in the horizontal direction and a light exit angle within 5 degrees in the vertical direction. When the light emitted by the third light source enters the third lens, the third lens has a light exit angle within 26 degrees in the horizontal direction and a light exit angle within 2 degrees in the vertical direction. Wherein the first lens, the second lens and the third lens are arranged in a straight line in order vertically to the ground, there is a first distance between the bottom end of the first lens and the top end of the third lens, and the first distance is not more than 200 mm.
