Description
Technical Field
The utility model relates to a technical field of lamps and lanterns, in particular to headlamp module.
Background
The lighting effect of a motor vehicle headlamp module is generally divided into high beam lighting and low beam lighting, and the lighting effect is mainly related to two factors: luminosity and angle. But the high beam lighting of current headlight module often has illumination luminance not enough, the light range is far enough, the facula appears in the play plain noodles, the light-emitting is even soft scheduling problem inadequately, often can't fully illuminate the region in car the place ahead, luminous dark space appears in the plantago side easily, light utilization ratio is general, and luminous effect is not good, influences vehicle illuminating effect, has the potential safety hazard. In order to achieve sufficient luminosity and range, some existing headlamp modules employ white laser as a light source, and the white laser is an illumination light source technology for generating high-brightness white light based on laser. Strictly speaking, "monochromaticity" is one of the basic characteristics of laser light, and thus laser light itself cannot be white, because "white" itself contradicts "monochromaticity". The "white laser" is an illumination technique for converting a monochromatic laser light into white light. Because the laser is used as an energy source, the white laser naturally has the gene of the laser, namely the characteristics of high brightness and high collimation. The conventional white laser realization method comprises the following steps: the white laser is formed by a synthesis mode, and the white laser synthesized by the method has the same collimation as the laser, so that a white light ray with a long propagation distance can be realized. This white light beam is expanded to form a white illumination spot. However, the use of multiple lasers leads to very expensive production cost, difficulty in wide popularization and application and limited application range due to complex and complicated structure, high material cost and multiple processing procedures, and moreover, a white laser spectrum consists of three linear spectrums of red, blue and green, and is discrete, so that the white laser spectrum is very easy to separate due to dispersion in subsequent optical treatment, and the white light is separated into three colors of red, green and blue again.
Therefore, how to realize one kind and be equipped with white laser structure and come as the far-reaching headlamp illumination, luminous hi-lite, high collimation degree, illumination brightness is sufficient, light range is far away, the grading mode is reasonable, luminous no dark space, the light-emitting is even soft, the luminous effect is ideal, and the simple novelty in design of white laser structure, only need use blue laser and yellow phosphorus powder can form white laser, but greatly reduced material and production and processing cost, simplify product structure and production and processing process, and the spectrum is stable, the headlamp module that can not take place dispersion is the technical problem that waits in the industry to solve urgently.
