Abstract
The utility model relates to a Fresnel lens which can decrease the dead weight of a lamp by approximately 3 percent and can improve the shock resistance and the service life of the lamp. The Fresnel lens comprises a containing structure and a sub-structure, wherein the containing structure and the sub-structure are fixedly connected together.
Description
Technical field
The utility model relates to a kind of Fresnel Lenses.Application example: car headlamp dipped beam projection lamp, LED dim head lights projection lamp etc.
Background technology
The development of Hyundai Motor light fixture is more and more faster, especially the headlamp technology is more and more higher, under the prerequisite of illumination, also carry out function conversion, in these technology the insides, the large percentage that projection lamp is used, and Fresnel Lenses is a necessary part in the projection lamp, but the material of lens is a glass at present, and glass is lower because of ratio of briquetting, along with the varying dimensions of thickness can become unstable, thereby cause functional lability even loss of function, and weight is heavier, also can causes the shock resistance of light fixture relatively poor.
Summary of the invention
The purpose of this utility model causes the size instability in order to solve present glass lens because of thickness exactly, thereby the problem of function reduction or loss of function when causing with other optics combination, a kind of Fresnel Lenses is provided, it is nearly 3% to utilize these lens can reduce the weight of light fixture itself, the shock resistance and the life-span of improving light fixture.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of Fresnel Lenses, it comprises subsumption architecture and minor structure, both are fixed together.
Described subsumption architecture and minor structure are connected together by supersonic welding.
Described subsumption architecture is a semisphere, and inside is step-like and lens combination is installed.
Fresnel Lenses of the present utility model is divided into altogether, a part is a subsumption architecture, another part is a minor structure, two parts utilize ultrasonic soldering (also can adopt other various existing welding manners, laser bonding etc. for example) method connects, the method of welding is the profile location, and inside dimension can arbitrarily cooperate, and is difficult for deviating from.
The beneficial effects of the utility model are: compact conformation, stable performance, weight saving.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1, subsumption architecture, 2, minor structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Among Fig. 1, subsumption architecture 1 adopts the special tooling location with minor structure 2, utilizes the method for ultrasonic soldering to weld, thereby guarantees its dimensional stability.
Claims (3)
1. a Fresnel Lenses is characterized in that, it comprises subsumption architecture and minor structure, and both are fixed together.
2. Fresnel Lenses as claimed in claim 1 is characterized in that described subsumption architecture and minor structure are connected together by supersonic welding.
