[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] The present embodiment provides a compact UAV taxiing light using matrix-type SMD LED lamp beads, refer to 1-3, including a lower shell 7, a light source board 6 is installed at the front end of the lower shell 7, a light-emitting LED lamp bead is installed in the center of the light source board 6, a pair of first cross-slot pan head screws 5 are installed at the front end of the light source board 6, a waterproof sealing ring 4 is installed at the front end of the first cross-slot pan head screw 5, an optical lens 3 is arranged at the front end of the waterproof sealing ring 4, an upper shell 2 is arranged at the outer end of the optical lens 3, cross-slot countersunk screws 1 are installed around the outer end of the upper shell 2, mounting brackets 10 are installed at the left and right ends of the lower shell 7, a pair of second cross-slot pan head screws 11 are installed at the front end of the mounting bracket 10, an electrical connector 8 is installed at the rear end of the lower shell 7, and cylindrical cross screws 9 are installed around the rear end of the lower shell 7.

[0022] Please refer to 2-3, the second cross recessed pan head screw 11, the mounting bracket 10, the cylindrical head cross screw 9, the light source board 6, and the cross recessed countersunk head screw 1 are all made of steel, the lower shell 7, the electrical connector 8, and the upper shell 2 are all made of silicone rubber, the optical lens 3 is made of PMMA, the light distribution of the light source board 6 is a bat-wing distribution, the light type of the light source board 6 is a strip, the effective scattering angle of the light source board 6 has a horizontal range of at least twenty-five degrees, and the effective scattering angle of the light source board 6 has a vertical range of at least six degrees.

[0023] Please refer to 1-3. In this scheme, the light source board 6 is first connected to the lower shell 7 with two first cross-slot pan head screws 5, and then the waterproof sealing ring 4, the optical lens 3, and the upper shell 2 are installed on the assembled lower shell 7 in turn, and then fixed to the lower shell 7 with four cross-slot countersunk screws 1, and then the electrical connector 8 is fixedly connected to the lower shell 7 with four cylindrical cross screws 9, and a pair of mounting brackets 10 are fixedly connected to the lower shell 7 with four screws and second cross-slot pan head screws 11. The connection between the upper shell 2 and the lower shell 7 is connected by threaded matching. The overall installation is cheap and easy to maintain. The design mainly solves the requirements of the installation space for the external dimensions and the weight requirements during use. The light source board 6, the upper shell 2, and the lower shell 7 are made of aviation aluminum, which has the characteristics of light weight and strong environmental adaptability.

[0024] Heat dissipation is the path of conducting the heat generated in the light source board 6 to the air. Heat dissipation mainly adopts heat conduction and heat convection. For this reason, when designing the heat dissipation system, the surface of the lower shell 7 is designed to be a plurality of parallel heat dissipation ring grooves, and high-efficiency thermal conductive silicone grease is used between the light source board 6 and the lower shell 7 to ensure good contact. The heat generated by the light-emitting LED lamp beads when working is conducted to the light source board 6 and then to the lower shell 7 through the high-efficiency thermal conductive silicone grease, and then to the outside by the lower shell 7. The setting of the heat dissipation ring groove not only increases the contact area between the lower shell 7 and the air, and quickly dissipates the heat on the lower shell 7, but also, without affecting the volume, by adding the heat dissipation ring groove on the lower shell 7, the weight of the lamp can be reduced, and the heat dissipation area can be increased, so that the convection effect of the lamp is better.

[0025] The taxi light has a bat-wing distribution and a strip-shaped light pattern. The effective scattering angle is required to be at least twenty-five degrees horizontally and at least six degrees vertically. The light distribution design uses a combination of an optical lens 3 and a matrix light source. The distance between the optical lens 3 and the light source is adjusted to achieve the desired light pattern. The matrix light source is located in the light source panel 6.

[0026] In order to meet the above requirements, the design mainly includes the design of light source and optical lens. The light source adopts LED light source, and the optical lens adopts PMMA elliptical optical lens 3, with a long axis of 50mm and a short axis of 46mm. In order to achieve the required strip light distribution, the light source adopts a matrix integrated rectangular light source with a length of 5.8mm, a width of 3.6mm, aviation white color, a color temperature of 6400K, and a power of 30W. When in use, the long side of the rectangular light source is parallel to the long axis of the elliptical lens. The light output angle can be changed in the horizontal and vertical directions by adjusting the distance between the light source and the optical lens 3. After optical anti-fake and actual light distribution verification, the distance between the light source and the optical lens 3 is set to 17-23mm, which can meet the vertical angle of 6 degrees. The requirement of horizontal light output angle of 25 degrees.
