Problems solved by technology
[0002] Most of the light sources on the existing automobile headlights are diffused through the lens and directly irradiated, which has a low utilization rate of the generated light, and some lamp bodies will also add a reflective cup around the light source for light concentrating. The cup body structure is A cylinder structure with a certain taper is placed around the light source to reflect the laterally diffused light, causing it to be emitted through the lens, but such a light utilization rate can only reach 50%-60%. High loss, poor overall effect

The invention discloses dual-reflecting cups with improved light utilization ratio for an automobile headlamp. The structure comprises main light sources realizing horizontally forward illumination, light-reflecting cups I cover the main light sources, each light-reflecting cup I is provided with a light-reflecting face I in the shape of a curved face, the light-reflecting faces I reflect light rays emitted by the main light sources to the side rear direction, and a plurality of virtual light-emitting points are formed through converging of the light rays. The structure further comprises light-reflecting cups II for receiving the virtual light-emitting points, and each light-reflecting cup II is provided with a light-reflecting face II for horizontally reflecting the virtual light-emitting points. The dual-reflecting cups have the advantages that the light utilization ratio is high, the light-reflecting faces are small, the integral function is perfect, and the practicability is strong.
Description
technical field [0001] The invention relates to a reflective cup, in particular to a double-reflective cup for automobile headlights with improved light utilization. Background technique [0002] Most of the light sources on the existing automobile headlights are diffused through the lens and directly irradiated, which has a low utilization rate of the generated light, and some lamp bodies will also add a reflective cup around the light source for light concentrating. The cup body structure is A cylinder structure with a certain taper is placed around the light source to reflect the laterally diffused light, causing it to be emitted through the lens, but such a light utilization rate can only reach 50%-60%. The loss is high and the overall effect is not good. Accordingly, the present invention proposes a double-reverse cup for automobile headlights that improves light utilization. Contents of the invention [0003] The object of the present invention is to overcome the s...
