Description

Technical Field

[0001] The utility model relates to the technical field of laser headlights, in particular to a laser bi - optic lens vehicle lamp structure. Background Technique

[0002] With the continuous development and innovation of the automotive industry, in order to ensure safe driving at night, people have put forward higher and higher requirements for the safety of automobiles. As a major safety component of automobiles, automotive lamps have greatly improved the safety of night driving in the past decade with the development of solid - state lighting technology and the application of new vehicle lamp technologies. A laser headlight pumps a high - power laser beam to excite a Ce:YAG phosphor conversion material, and the transmitted blue laser and the yellow fluorescence generated by excitation produce a high - brightness white light source perceived by the human eye through the principle of optical color mixing.

[0003] In the prior art, CN117190114A discloses a laser headlight with a double - layer phosphor structure. The technical problem of "after long - term use, the phosphor structure at the laser focus point will be carbonized due to long - term laser heating and burning, and then lose the ability to react with blue laser, resulting in a significant decline in the overall lighting effect of the laser headlight and forming a safety hazard" is proposed in this solution. However, the solution proposed in this solution still has room for improvement. Secondly, in this solution, the same light source can only perform single - color illumination, and the aesthetics is not ideal.

[0004] Therefore, a laser bi - optic lens vehicle lamp structure is proposed, which has the advantages of preventing phosphor structure carbonization and double - light illumination, thus solving the problems in the above - mentioned background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a laser bi - optic lens vehicle lamp structure is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A laser bi - optic lens vehicle lamp structure, including a lamp base and a lamp cover. A laser light source is embedded and installed in the lamp base, and a lamp cover is installed corresponding to the laser light source at the right end of the lamp base. A first lens is embedded and installed at one end of the lamp cover close to the laser light source, and a second lens is embedded and installed at the end of the lamp cover far from the laser light source. A reflecting bowl is installed on the inner wall surface of the lamp cover. A reflecting disk is arranged between the first lens and the second lens, and a side rod is arranged on the side of the reflecting disk and is inserted and connected with the reflecting bowl. Fluorescent layers are coated on both sides of the reflecting disk, and annular rough surfaces are arranged at the edges of both sides of the reflecting disk. A through - hole is opened at one end of the side rod extending out of the reflecting bowl. Two fixing blocks are symmetrically installed on the outer side surface of the reflecting bowl corresponding to the side rod, and a threaded column is installed between the two fixing blocks through a nut. The threaded column is inserted and connected with the through - hole of the side rod.

[0007] As a further description of the above technical solution: A positioning post is welded to one end of the side rod away from the reflection disc. Positioning grooves are correspondingly formed on the surfaces of the two fixing blocks for the positioning post, and the positioning post extends into the positioning groove of one of the fixing blocks.

[0008] As a further description of the above technical solution: The reflection disc is installed on the emission path of the laser light source beam, and the fluorescent layers on both sides of the reflection disc are both made of YAG phosphor conversion material.

[0009] As a further description of the above technical solution: The concave surface of the reflector bowl is provided with a reflecting surface, and a through hole is correspondingly formed on the surface of the reflector bowl for the side rod.

[0010] As a further description of the above technical solution: An installation protrusion is provided at the right end of the lamp holder, and a sealant is filled at the connection between the installation protrusion and the lamp shade.

[0011] As a further description of the above technical solution: Threaded heads are provided at both ends of the threaded post, and a nut is threadedly connected to each threaded head.

[0012] The utility model has the following beneficial effects:

[0013] In the utility model, a reflection disc is installed on the emission path of the laser light source beam, and a side rod is provided on the side of the reflection disc and is inserted and connected with the reflector bowl. By removing the threaded post inserted between the two fixing blocks and the side rod, and then rotating the side rod 180 degrees, the carbonized fluorescent layer on one side of the reflection disc is turned away from the emission path of the laser light source beam, while the non-carbonized fluorescent layer on the other side of the emission disc continues to play the role of converting laser into white light. Compared with the prior art, it is not necessary to directly replace the entire headlight, and the convenience of maintenance is increased, avoiding the problem that the overall lighting effect of the laser headlight is greatly reduced due to the carbonization of the fluorescent layer, forming a safety hazard. At the same time, since fluorescent layers and annular rough surfaces are provided on both sides of the reflection disc, when the laser light source beam passes through the first lens and irradiates on the reflection disc, a part of the laser light reacts with the fluorescent layer of the reflection disc and is converted into white light, and the reflector bowl reflects the white light out. Another part of the laser light contacts the annular rough surface at the edge of the reflection disc to form diffuse reflection, and the reflector bowl reflects the laser light weakened by the diffuse reflection out, so as to form the effect of dual-light illumination on the basis of the same light source, with good aesthetics.

A first lens 4 is embedded and installed at one end of the lamp cover 2 close to the laser light source 3, and a second lens 6 is embedded and installed at the end of the lamp cover 2 far from the laser light source 3. A reflector bowl 5 is installed on the inner wall surface of the lamp cover 2. A reflector disc 7 is arranged between the first lens 4 and the second lens 6, and a side rod 8 that is inserted and connected to the reflector bowl 5 is arranged on the side surface of the reflector disc 7. Fluorescent layers 9 are coated on both sides of the reflector disc 7, and annular rough surfaces 14 are arranged at the edges of both sides of the reflector disc 7. A through hole 15 is opened at one end of the side rod 8 extending out of the reflector bowl 5. Two fixed blocks 10 are symmetrically installed on the outer side surface of the reflector bowl 5 corresponding to the side rod 8, and a threaded post 12 is installed between the two fixed blocks 10 through a nut. The threaded post 12 is inserted and connected to the through hole 15 of the side rod 8. Regarding the laser headlight, the parts not involved in this device are the same as the prior art or can be implemented by using the prior art;

[0022] In one embodiment, a positioning post 13 is welded to the end of the side rod 8 far from the reflector disc 7, and positioning grooves 11 corresponding to the positioning post 13 are opened on the surfaces of the two fixed blocks 10. The positioning post 13 extends to the inside of the positioning groove 11 of one of the fixed blocks 10. Through the arrangement of the positioning post 13 and the positioning groove 11, the side rod 8 can only rotate 180 degrees, which is convenient for rotation and positioning.

[0023] In one embodiment, the reflecting disc 7 is installed on the emission path where the laser light source 3 is focused, and the fluorescent layers 9 on both sides of the reflecting disc 7 both adopt YAG phosphor conversion materials. The fluorescent layers 9 on both sides of the reflecting disc 7 are used to rotate and replace the fluorescent layer 9 being talked about.

[0024] In one embodiment, a reflecting surface is provided on the concave surface of the reflector bowl 5, and a through hole is provided on the surface of the reflector bowl 5 corresponding to the side rod 8. The through hole is provided to facilitate the installation of the side rod 8.

[0025] In one embodiment, an installation protrusion is provided at the right end of the lamp holder 1, and a sealant is filled at the connection between the installation protrusion and the lamp cover 2.

[0027] Working principle:

[0028] When in use, when the user uses the laser headlamp, since the fluorescent layers 9 and the annular rough surface 14 are provided on both sides of the reflecting disc 7, when the laser light source 3 is focused and passes through the first lens 4 and irradiates on the reflecting disc 7, a part of the laser light reacts with the fluorescent layer 9 of the reflecting disc 7 and is converted into white light, and the reflector bowl 5 reflects the white light out. Another part of the laser light contacts the annular rough surface 14 at the edge of the reflecting disc 7 to form diffuse reflection, and then the reflector bowl 5 reflects the laser light weakened by the diffuse reflection out, so as to form the effect of double-light illumination on the basis of the same light source. When the fluorescent layer 9 on one side of the reflecting disc 7 is carbonized, by removing the threaded column 12 inserted between the two fixing blocks 10 and the side rod 8, and then rotating the side rod 8 by 180 degrees, the carbonized fluorescent layer 9 on one side of the reflecting disc 7 is deviated from the emission path where the laser light source 3 is focused, and the non-carbonized fluorescent layer 9 on the other side of the emission disc continues to play the role of converting laser into white light, without directly replacing the whole headlamp, reducing the maintenance cost.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
