Lens unit and application thereof in multifunctional automobile lamp

Abstract

The invention provides a lens unit and application thereof in a multifunctional automobile lamp. The lens unit comprises a light incident surface and a light emitting surface; a light source is arranged on one side close to the light incident surface which is provided with a first light receiving area, a second light receiving area and a third light receiving area; the first light receiving area is particularly formed by multiple mutually parallelly arranged first light receiving raised lines protruding in the direction opposite to a light path; the second light receiving area is arranged on the first light receiving area, and particularly formed by multiple mutually parallelly arranged second light receiving raised lines protruding in the direction opposite to the light path, and the third light receiving area is arranged on the second light receiving area; light rays is refracted and spread to be emitted through the first light receiving area, the second light receiving area and thethird light receiving area from the light source. According to the technical scheme, one type of lens unit can meet many different requirements of European standard and American standard lamps simultaneously, and the lens unit is simple in structure and large in light emitting angle.

Description

technical field [0001] The invention relates to the field of automobile lamps, in particular to a lens unit and its application in multifunctional automobile lamps. Background technique [0002] At present, signal lights using traditional Fresnel lens structure can only meet the three functions of rear position lights, brake lights, and rear turn lights in the US regulations, but cannot meet the functions of rear position lights, brake lights, and rear turn lights in European regulations. , European regulations require a large angle of 80 degrees to emit light, and in addition, it cannot be shared to meet the function of the reversing light. Generally, a vertical stripe structure lens must be designed to make the reversing light. And the traditional Fresnel structure lens such as Figures 1 to 2 As shown, the pattern is complicated, there are more sharp corner processing requirements, the mold cost is high, and the light angle cannot meet the demand.
