Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
As shown in fig. 1, the utility model provides a car light module, including light source 1 and convex lens 3, light source 1 with be equipped with fresnel lens 2 between the convex lens 3, the light that light source 1 sent is incited after fresnel lens 2 assembles on the convex lens 3.
The utility model discloses an adopt fresnel lens 2 to assemble the light that light source 1 sent, can make light source 1 directly expose, be favorable to improving the heat dispersion of car light module, improve light source 1's life. In addition, the Fresnel lens 2 has light weight, is planar, has small volume and low space requirement, so that the car lamp module has a simple structure and small space occupation, can realize the miniaturized design of the car lamp module, can also have more scope of play in assembly, is beneficial to designing more flexible and changeable car lamps, and ensures that the space utilization efficiency and the light distribution efficiency of the car lamp module are higher; and the Fresnel lens 2 has lower manufacturing cost, better light condensation effect, economy and practicality.
Wherein, work as when light source 1 is the passing light source, the car light module can regard as passing light car light module, work as when light source 1 is the distance light source, the car light module can regard as distance light car light module.
The utility model discloses an among the car light module, final car light module's spotlight effect has been decided to distance between fresnel lens 2 and the light source 1:
when the light source 1 is located at the focal point of the fresnel lens 2, a quasi-parallel light path as shown in fig. 1 is obtained;
when the distance between the light source 1 and the fresnel lens 2 is smaller than the focal length of the fresnel lens 2, as shown in fig. 2, a part of the light emitted from the light source 1 passes through the fresnel lens 2 to form a quasi-parallel light path;
when the distance between the light source 1 and the fresnel lens 2 is greater than the focal length of the fresnel lens 2, the fresnel lens 2 converges the light emitted from the light source 1 as shown in fig. 3.
Therefore, the distance between the light source 1 and the fresnel lens 2 can be adjusted according to actual conditions to meet different light beam requirements. Also, the size of the fresnel lens 2 may be changed according to the divergence angle of the light source 1 to achieve more light collection.
