[0023] In order to further understand the features, technical means and the specific purpose reached of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiment.

[0024] REFERENCE Figures 1 to 7 .

[0025] The utility model discloses a lamp structure realizing closed light ring around article, including mounting seat 11 and install at least one laser light source 12 of mounting seat 11 assembly space 21, first high frequency swing mirror device 19, second high frequency swing mirror device 18, main control circuit board, first high frequency swing mirror device 19 includes first drive motor 16 and first swing mirror 15, and second high frequency swing mirror device 18 includes second drive motor 13 and second swing mirror 14, and laser light source 12, first drive motor 16, second drive motor 13 all are connected with main control circuit board electricity, the rotation scanning direction of second swing mirror 14 and the rotation scanning direction of first swing mirror 15 constitute perpendicular relation, still including conical reflecting surface 17 and transparent face shield 10, mounting seat 11 is inlayed and is arranged in transparent face shield 10, and the top of transparent face shield 10 and assembly space 21 form laser reflection space 20, and laser light source 12 corresponds to install in the inside wall of assembly space 21, and first high frequency swing mirror device 19 is installed in the other inside wall opposite laser light source 12 of assembly space 21, and second high frequency swing mirror device 18 is installed in the bottom of assembly space 21 and is located between laser light source 12 and first high frequency swing mirror device 19, and conical reflecting surface 17 corresponds to fixedly installed in the top of transparent face shield 10 inner chamber and the position corresponds with the light scanning direction of first swing mirror 15. The light outlet of laser light source 12 is installed with beam expander, because the divergence angle of laser determines the beam diffusion degree, directly influences the size of light spot, and the embodiment is compressed divergence angle through beam expander, to control the thickness of light spot line.

[0026] In the embodiment, the laser light source 12 is set as a laser. The mounting seat 11 is set as a composite mounting seat reinforced by PBT resin and 30% glass fiber. The surface of the mounting seat 11 is formed with a polishing surface. The reflectivity of the mounting seat 11 is set as 3%, and the transmittance is set as 0%. The transparent face shield 10 is set as a PC2407 face shield. The transmittance of the transparent face shield 10 is set as 88%, and the reflectivity is set as 0%. The conical reflecting surface 17 is set as a PC2407 reflecting surface. The surface of the conical reflecting surface 17 is formed with an aluminum plating layer. The reflectivity of the conical reflecting surface 17 is set as 85%, and the transmittance is set as 0%. The first swing mirror 15 and the second swing mirror 14 are both set as quartz swing mirrors. The reflecting surface of the first swing mirror 15 and the second swing mirror 14 is formed with a reflective plating layer. The reflectivity of the reflecting surface of the first swing mirror 15 and the second swing mirror 14 is set as 90%, and the transmittance is set as 0%.

[0027] The conical reflecting surface 17 is used for changing the light-emitting angle of the closed light ring formed by the laser 22 emitted from the laser light source 12, the second galvanometer 14 and the first galvanometer 15 in sequence, and scanning to form the closed light ring reflected to the ground or the illuminated surface, that is, the laser 22 emitted from the laser light source 12 is changed in the horizontal direction light-emitting angle by the second galvanometer 15 rotating scanning, the laser 22 after the angle is changed is scanned and reflected to the first galvanometer 15, the first galvanometer 15 rotates to scan and reflect the laser 22 from the second galvanometer 14 again and changes the light-emitting angle of the laser 22 in the vertical direction, so that the light emitted by the laser is offset in the horizontal and vertical directions, and by controlling the rotating angle of the second galvanometer 14 and the first galvanometer 15, a circular light spot is output, and the circular light spot is reflected to the ground or the illuminated surface by the conical reflecting surface 17 to form a closed light ring. Since the laser naturally has a very small divergence angle, a larger area can be covered by fast scanning of the high-speed galvanometer, and the human eye will regard the fast-moving light spot as a continuous area light source effect. The range of the light circle on the ground can be changed by changing the conical angle of the conical reflecting surface 17 and changing the angle of the last light emission. When the lamp structure is placed on the top of an article, a closed light ring surrounding the article is formed, for example, the lamp structure is placed as a car ground light on the top of the car, and a light circle is formed around the car, and the light circle is continuous and the light spot is not separated due to the vibration of the car. On the basis of the structure of the embodiment, various customized patterns can be formed around the article by using the galvanometer principle.

[0028] As another preferred embodiment, the laser light source 12 can also be composed of three lasers and a light mixing system, and by such a structure, a color light circle can be realized. In actual use, red, green and blue three primary color lasers are adopted, the light is input into the light mixing rod group after being focused by the lens group, and the spatial differential light mixing is realized by total reflection. The light mixing rod can be equipped with a rotating mechanism to optimize the uniformity, and finally the beam shaping and projection imaging are realized by the secondary lens group and the DMD device.

[0029] The above-described embodiments only express the various embodiments of the present application, the description is more specific and detailed, but it cannot be understood as limiting the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
