Abstract
The invention relates to the field of automobile parts, in particular to a light reflecting sheet in a car lamp. The light reflecting sheet which is stuck on the car lamp is of the shape of a bowl mouth. The bulb of the car lamp is arranged in the center A of the arc surface of the light reflecting sheet. Infrared reflecting coating layers are arranged at intervals from the center A of the arc surface of the light reflecting sheet. A transition layer for reflecting visible light is formed between every two adjacent infrared reflecting coating layers. The infrared reflecting coating layers are ring-shaped. The centers of the infrared reflecting coating layers are overlapped with the center of the bow mouth. The infrared reflecting coating layers reflect infrared light, the transition layers reflect visible light and the infrared reflecting coating layers and the transition layers are not mutually affected. Therefore, the car lamp acquires more images, the definition of the images is improved, a driver can observe a driving environment anytime and the driving safety is improved.
Description
Technical field
The present invention relates to the auto parts and components field, particularly be used for the reflecting piece in the car light.
Background technology
Along with growth in the living standard, to the lifting that vehicle safety requires, automotive lighting has been not only to satisfy the visual requirement of naked eyes; Night vision function has become one of main safe practice of present automotive lighting, and the automobile headlamp lamps with infrared reflection coating that adopt are realized night vision function more at present, but coating is too concentrated; The zone of reflect visible light is too little; Be unfavorable for gathering more, image more clearly, thereby influence the definition of image, leave potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of imaging and be used for the reflecting piece in the car light clearly.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: a kind of reflecting piece that is used in the car light, and the reflecting piece that is sticked on car light is bowl-mouth shape, and the bulb of car light is positioned at the A place, cambered surface center of reflecting piece; This reflecting piece is provided with infrared reflection coating at interval from A place, cambered surface center; Constitute the transition zone of reflect visible light between adjacent two infrared reflection coatings, it is circular that infrared reflection coating becomes, and its center overlaps with the rim of a bowl center of reflecting piece.
Since adopt above technical scheme, the infrared reflection coating reflects infrared light, the transition zone reflect visible light is independent of each other, and makes the more image of car light collection, improves the definition of image, and the driver can observe the environment of driving at any time, improves travel safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Like Fig. 1, a kind of reflecting piece that is used in the car light, the reflecting piece 10 that is arranged on the car light is bowl-mouth shape; The bulb 20 of car light is positioned at the A place, cambered surface center of reflecting piece 10, and this reflecting piece 10 is provided with infrared reflection coating 11 at interval from A place, cambered surface center, constitutes the transition zone 12 of reflect visible light between adjacent two infrared reflection coatings 11; 11 one-tenth of infrared reflection coatings are circular, and its center overlaps with the rim of a bowl center of reflecting piece 10, and infrared reflection coating 11 is equivalent to be set in endless belt on reflecting piece 10 outer walls; Infrared reflection coating 11 reflects infrared light wherein, transition zone 12 reflect visible light are independent of each other; Make the more image of car light collection; Improve the definition of image, the driver can observe the environment of driving at any time, improves travel safety.
The width of described reflecting piece 10 outside infrared reflection coating 11 of A from the cambered surface center reduces successively, that is to say that the width dimensions of the infrared reflection coating 11 nearest apart from light source is maximum, and is minimum apart from the width dimensions of light source infrared reflection coating 11 farthest.
The width of described reflecting piece 10 outside transition zone 12 of A from the cambered surface center increases successively.
The external boundary of the infrared reflection coating 11 of outmost turns is the first arc length L1 to the distance of the cambered surface center A of reflecting piece 10 on the described reflecting piece 10; The distance of the outward flange of reflecting piece 10 A to the cambered surface center is the second arc length L2, and wherein the span of L1 is 2/3～4/5 of L2.
The consistency of thickness of described infrared reflection coating 11.
Described infrared reflection coating 11 is followed successively by 1.2mm, 1.0mm, 0.75mm, 0.5mm, 0.25mm, 0.20mm, 0.15mm from the outside width of the cambered surface center of reflecting piece 10 A.
Described transition zone 12 is followed successively by 0.5mm, 0.75mm, 1.0mm, 1.25mm, 1.5mm, 8mm from the outside width of the cambered surface center of reflecting piece 10 A.
As shown in Figure 1, the reflecting piece 10 among the present invention is sticked on the inwall of car light, and bulb is positioned at the A place, cambered surface center of reflecting piece 10; Be provided with 4 infrared reflection coatings 11 on the reflecting piece 10 altogether, that is to say four annular infrared reflection coatings 11 of outside separation, and its width be followed successively by 1.2mm, 1.0mm, 0.75mm, 0.5mm from A place, cambered surface center; Then transition zone 12 is provided with three altogether, and its width is followed successively by 0.5mm, 0.75mm, 1.0mm, the consistency of thickness of four infrared reflection coatings 11; Therefore the degree of reflection to IR is consistent; This is simple in structure, and the regional space of reflected infrared ray and visible light is arranged, is independent of each other; Gather more image, improved the definition of image.
