Detailed Description
The utility model will be described in further detail with reference to the drawings and the detailed description. The embodiments of the present utility model have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.
As shown in fig. 1-5, the technical scheme of the utility model is that the rear fog lamp comprises a lamp housing 1, an outer lens 2, an LED lamp 4 and a radiator 5; the outer lens 2 is arranged on the lamp housing 1 in a semi-wrapping mode, an installation space is formed between the outer lens 2 and the lamp housing 1, the LED lamp 4 is arranged on the lamp housing 1 and located in the installation space, the Fresnel pattern structure 3 is arranged on the inner surface of the outer lens 2, and the optical axis of the LED lamp 4 coincides with the center of the Fresnel pattern structure 3. The LED lamp 4 is combined with the radiator 5, LED light attenuation is reduced, the radiator 5 is fixed on the lamp housing 1 through screws at two ends, the outer lens 2 is welded on the lamp housing 1, and finally direct light of the LED lamp 4 is diffused through the Fresnel pattern structure 3 on the inner surface of the outer lens 2, so that a rear fog lamp function is realized.
The Fresnel pattern structure 3 is a plurality of groups of concentric ring assemblies. The width D1 of each circular ring is 0.8-3mm. The above arrangement can ensure uniformity of light source divergence, and meet light source divergence requirements of fog lamps.
The outer lens 2 is made of transparent plastic material, and has a smooth structure. As shown in fig. 4, the thickness L1 of the outer lens 2 is 2-4mm. The color of the outer lens 2 may be red or white.
The distance L2 between the LED lamp 4 and the Fresnel pattern structure 3 on the outer lens 2 is not less than 5mm. The distance can meet the requirement of light divergence without weakening the light source.
The LED lamps 4 are arranged along the length direction of the lamp housing 1 in a plurality, and the number of groups of the Fresnel pattern structures 3 is the same as the number of the LED lamps 4. The LED lamps 4 and the Fresnel pattern structures 3 arranged in a plurality of groups can meet the overall optical effect.
It should be noted that the optical structure of the present solution may also be suitable for reversing, steering lamps and braking.
It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art and which are included in the embodiments of the present utility model without the inventive step, are intended to be within the scope of the present utility model. Structures, devices and methods of operation not specifically described and illustrated herein, unless otherwise indicated and limited, are implemented according to conventional means in the art.
